Have you been to your dealer for Warranty work on your 07? Whats your list

[AV-03/07]

My list,

Power steering fluid leak, Replaced-Steering RACK

Engine oil leak, back of engine.
Transmission problem, slipping during upshifting Trannyman !

whats your list?

[AVcop]

I guess I've been fortunate. The only warranty work I've had is the dead battery problem resolved, and that's it.

[Firehunter]

Only thing has been the aspirator for the auto climate control.  It is located right above the driver and was vibrating/rattling like crazy.  Fixed now. . .Much better

[brianm]

Mine is in right now for a couple of things.  The drivers side mirror glass was vibrating and they could not tighten it so they are replacing the entire mirror.  Also I had developed a  whine in the power steering pump.  There was supposedly a GM bulletin about flushing and replacing the fluid with synthetic.  They did that with no improvement so they are now replacing the entire pump.  There is also an occasional creak in the right side of the dash that happens mostly when cold outside so of course with it being 90 degrees they cannot pinpoint the problem.  The tec heard it a couple of times but cannot get it to happen enough to figure out where it is coming from.  Doing the battery recall (although I have not had a problem) and the flex fuel update while it is there. They did the BCM update for the phantom wipe on my second oil change.  Besides those things that is the only issues.  I have just under 20k miles.

I also have that (Buzz) in the power steering pump, thought i was the only one, guess not.

I thought i would deal with the more serious issues first, then the really irritating ones when i have spare time.

[alex_lee88]

ya i have it too, but they said it wasnt that that was making the noise...... 

[mike socal]

4100 miles, 5.3 liter Z71:    rear seal & seal from rear of block to trans housing leaking engine oil, and front differential plug gasket replaced...   front sway bar passenger side bolt attachement was 2 threads away from falling out also....

[07blueLTZ]

07 LTZ with 15,000 miles and the tranny went out....I was at a light and pressed the gas and there was a loud clank noise and next thing I had no reverse, drive, or 2nd gear just   first...

[Cabinetman]

I've got just under 10k miles and so far I have had it in for a dash rattle that has yet to be fixed and to have the rear end rebuild due to gear whine which came back less than 1k after the rebuild.  I really like the Av, but if they don't get my rattles fixed I'm going to buy something else.

[msdinsp]

mine hasn't gone back in yet, but when it does, the trim on the drivers door under the window, isn't clipped on. Raises up about 1/2" when you close the window, and can be pulled off with no effort.

[steve841]

I had my trim replaced... then someone here mentioned to just pull off the trim, grip the inside mounting areas and squeeze them time ...    waste of time at the dealer for this one.

I figured it's an easy fix, but I'll have them do it when I have to take it in for something else.

[oilfieldtrash]

I've had mine for eleven months, 9200 miles, zero problems.   

[USA1fan]

I had my trim replaced... then someone here mentioned to just pull off the trim, grip the inside mounting areas and squeeze them time ...    waste of time at the dealer for this one.

Yep.  My passenger side front door trim was doing the same thing, so I mentioned it the last time I had the Av in for the oil change.  The guy took half a second to pull it off, squeezed it a bit (metal underneath or something, so he says- I never checked), then put it back on.

Ta-Da!  Problem gone, just like that.

[chadman2815]

Remote start/dead battery
Windshield wiper scratched the hell out of window
Phantom Airbag light
Wind noise from drivers side window
Thumping noise when turning left
Rear main seal leaking as I type this haha

Hmmm our Av's must of come off the assembly line in order, I have the mirror problem and the power steering wine along with an A/C compressor chatter when it first starts...will bring it to the dealership after the nationals as I cannot have it tied up at this time.

Took it in the shop today for brake squeal (Fixed) A/C compressor chatter (Fixed), Drivers side Mirror twitches on the freeway (work in progress) Power Steering Pump Wine (Work In Progress) A/C switch sticks (Work In Progress)

[AV-03/07]

I really like the Av, but if they don't get my rattles fixed I'm going to buy something else.

Rattles! I wish I had rattles, I would rather deal with that than my oil leaks and slipping tranny any day!

Hmmm our Av's must of come off the assembly line in order,

This is something i can agree with!

[mike socal]

Took it back  two weeks after they replaced rear main seal....seems they removed the exhaust system to replace rear seals...then the exhaust manifold gasket at the header pipe is leaking. Got it back today, they said they stripped a bolts and broke one trying to get it off and had to remove entire exhaust manifold & replace gasket and put in all  new bolts...I looked at it when I got home, one bolt holding the heat cover is  missing and the flange bolt still looks stripped and they put a nut on the top which is only 1/2 threaded onto the bolt! Left a bitchy message on the service departments message line as they were now closed.  The studs are supposed to be threaded in from the bottom side of the header to flange connector into the header.  I get it back and see a nut, with the threads of the stud only 1/2 of the way into the nut threads at best on the top side of the joint.   I have a strong suspicion some lunkhead tried the easy way to fix the gasket leakage problem by putting an air wrench with 200 psi onto it and tried to tighten it, but managed to strip it and break the other bolt.  Can anyone advise am I right that the exhaust manifold is the threaded side of this connection?  Let you know what they have to say....

Just an update on mine.  The power steering pump was replaced and the whine is gone.  The creak in the right side of the dash was not the dash.  It turned out to be a little tab that is on the hood hinge on that side.  The tab was rubbing against the inner cowl when the temperature (expansion/contraction) was right.  A little bend by the tech and the creak has vanished.

The mirror on the other hand they are working on again.  They actually replaced the entire mirror.  It was in the shop for two days while they waited for the paint shop to color match the new mirror and then reinstall.  The paint work came back horrible with all kinds of junk in the paint and the new mirror vibrated worse than the one they replaced.  So I just took it back in for them to try again on that one.  This is the second day in the shop this time and I still do not have a call to come pick it up.  They did put me in a rental so I am not picking it up until its fixed.  Funny that the 2007 Silverado that I am renting has the same mirror and no vibration. 

[DarrenRD]

Leaky sunroof (been in 3 times, new seal to be installed tomorrow).
Drivers side mirror vibration (adjusted, still vibrates, replaced mirror, still vibrates, has to go back in tomorrow).
Power locks stopped working (needed reprogrammed).

Love the truck but getting tired waiting for something to break next.   I thought my Silverado was a pain. . .

[madandru]

Mines is in right now.  .  .  

First - ECM upgrades and Driver door lock fell into the door.

Second (now) - Airbag Swap (Dunno what thats about) and replaced bad O2 censors @ 14K

That reminds me.  .  .   The side mirror on the right side doesn't auto-dim at night and hasnt since delivery its one of those things that arent so important but notice every now and then.   I'll send an email about that one.

I dont believe the right side mirror is meant to dim ....  only the left.

[AV-03/07]

Power steering fluid leak, Replaced-Steering RACK, REPLACEMENT rack leaks worse than original!

Engine oil leak, back of engine, Fixed-Replaced Crank Pos sensor.


Transmission problem, slipping during upshifting under load  ,Trannyman ! STILL SLIPPING

[izzypop]

LTZ 4x4:
Truck running rough at idle and rattling under hood
#7 cylinder misfire faulty spark plug
What sucks is no "warning lights" at all I had to take it to the dealer and show them the problem. While sitting in the dealer service parking lot showing them the problem a warning light flashed for a couple seconds "service traction control"
You would think there should be a check engine light or something. The person borrowing my truck yesterday did say "it did feel way slower than my 98 silverado at take off" I said "It's always been like that"

[USA1fan]

The person borrowing my truck yesterday did say "it did feel way slower than my 98 silverado at take off" I said "It's always been like that"

That's the difference between the 5.7 powerband (+ the 98's lighter weight overall) and the 5.3's.  My father said the same thing when he compared his 98 Chevy pickup to his 04.

[goatboy]

mine must have been built on a weds, only thing i needed was a bad bed cover panel, humped up in the heat, thats it, no drips or lights or anything, love love love my truck

[Denman]

The AV is going in for Sticking A/C controller button, the part was ordered and ready to be installed, brake squeal, Drivers side mirror oscillation (known issue GM is NOT issuing any new mirrors as it is an actuator problem which is being worked on) this will be a down the road fix. A/C compressor squeal/chatter sounds like a compressor clutch but it is intermittent (investigation continues). Moreover, the power steering is a little noisy.

[lteeples]

It sucks that this topic has more post here than any other I have read.  I feel very fortunate that my truck has not had any problems.  Except rattles, but that comes standard with GM products.  Rest asure, no body makes a decient vehicle.  I have givin them all a chance now.

Dead battery problem.

Traced to the updated programming which was discovered to have not been done properly.

All in all, very enjoyable experience other then this minor problem which was quickly diagnosed and resolved.

[chevyconvert]

HOLY COW...Sounds like the '70's GM products alll over again.
Hopefully some of these things have been solved on my '08......
although window wind noise, and my driver's side mirror image vibrates...

Geez, they make 'em in Mexico you'd think they would be well assembled


Hopefully, there's lots of people with ZERO problems......Hmmm...

This bulletin is being revised to update warranty information.  Please discard Corporate Bulletin Number 05-06-01-034D (Section 06 -- Engine/Propulsion System).
--------------------------------------------------------------------------------
Condition
Some customers may comment on an engine oil leak.

Cause
Upon initial diagnosis, it may be determined that the leak is coming from the rear cover gasket.  This condition may be caused by engine block porosity on the sealing surface.  This issue pertains to aluminum block applications only.

Correction
Follow the steps for Oil Leak Diagnosis in SI to determine the source of the leak.  If the leak has been diagnosed as coming from the engine rear cover assembly, refer to Engine Rear Cover Replacement in SI and remove the engine rear cover assembly.  Inspect for engine block porosity where the engine rear cover mates to the engine block.  If porosity is found anywhere on the sealing surface, use the following procedure to apply RTV to repair the engine block porosity.  Refer to the illustration below.

Important: Clean any residual oil from the block and cover before applying the sealant in the next step.

Wipe a small amount of RTV, P/N 12378521 (in Canada, use P/N 88901148), onto the surface using a plastic scraper to fill the porosity.
Remove any excess RTV material, especially from inside the high pressure oil passage.  Refer to #1 in the above illustration.
The joint may be closed immediately after applying the RTV.  Total joint time after the RTV has been applied must be under 20 minutes.
Important: Refer to Engine Rear Cover Replacement in SI and follow the tightening specifications and sequence.

Reinstall the engine rear cover using a new gasket and a new crankshaft rear main seal.  Refer to Engine Rear Cover Replacement in SI.

2007 LTZ

Transmission at zero miles (factory forgot a seal and it burned up on the way home from the dealership)
Wiper arm squirted water straight up in the air (Split hose)
Missing clips in rear glass weatherstrip (hung down)
Navigation system screen rolled (failed diagnostic test and was replaced)
Battery died
Traction light - no code - blamed on battery
Brake squeal like a city bus
Dash rattle

Has only been to the dealer twice. All was fixed and all seems well otherwise. 12 mpg and lovin it!

Love the truck.

[izzypop]

and another one for me today....
rear seal & seal from rear of block to trans housing leaking engine oil

[AVnFun]

Fianally, I have to go to the dealer for something.. My storage lids won't lock, I never tried to lock them before, they seem to be stuck.

 

[Motordawg]

Dead battery problem.

Traced to the updated programming which was discovered to have not been done properly.

All in all, very enjoyable experience other then this minor problem which was quickly diagnosed and resolved.

Update on my own post here.

No problem since the programming was redone correctly. The dead battery problem, not having changed any of my routine, has not surfaced again.

[Silver07]

4700 miles and no problems.  Put in gas, drive, listen to XM radio and enjoy so far!

[mtmac57]

07 LTZ. . 7500miles. . . battery problem killed it. . . did not recvd recall notices. . had service bull work done--battery/flex fuel/remote start reprogram. . . . also the window outside moldings falling off--dealer ordered replacement--will try the squeeze method.

[07AvySS]

Had my 07 LS just under 2 months, 2500 miles...so far so good.

Except it now automatically steers into the nearest gas station...lol

[1Fastrider]

Tire sensors.  Delivered not working.  Dropped it off to fix and worked for about 10 miles and not working again.  They say to come in again but I now hate this dealer.

[plutnicki]

I bought mine as a demo with 9k miles on the clock.  It's now got just under 11k.

It was delivered with one tire plugged and the other tire had a slash in it.  Didn't know it until the plug started leaking.  Dealer replaced both front tires, but forgot to balance one.  Returned and upon balancing all 4 tires, found another wheel out of line and replaced the wheel.  Picked it up and truck still vibrated, so I had the tires rebalanced at a tire store.  It's better now, but I think it still might vibrate more than it should.   Possibilities in my mind include:

Mine has the 20 inch wheels, and with so little sidewall, do you expect a rougher ride than otherwise?

[Motordawg]

The tire sensors never worked when I picked up mine, new off the lot.

This should have been an indication that the reprogrammed ECM failed. But, I didn't know that at the time. I then started to have battery charging failure.

Now I know that this WAS an indication that the ECM programming did not take.

Take your Avy back to A dealership and have them completely go through the ECM programming. The tire sensors not working is an indication that the ECM programming was done incorrectly, or failed.

You will start to experience battery failure, as I did, if you don't get the ECM programmed correctly. I was advised that the tire sensors not working is an indication that the ECM updating failed.

I have had my Avy for nearly six months. Other then this battery failure, attributed to improper ECM reprogramming, I have had no problems and really enjoy my Avy.

I have an LTZ with 20's and the ride is absolutely smooth - no vibration. It sounds like you may have one or more bad tires.

Your comment about "so little sidewall" gives me the impression that you have aftermarket tires and wheels?  Correct?

I have OEM 20" tires and rims and the ride is totally sweet. I have not lowered the rear, as I don't want to change the comfortable ride.

[plutnicki]

No, my tires/wheels are bone stock 20s.  Biggest I've ever had for a truck, seems like hardly any sidewall to me (as compared to 15s, 16s and 17s...).

On smooth roads, it's great, but seems like any rougher pavement causes a vibration, but from your descriptions, sound like there may still be something up...  Really don't want to go back to the stealer, I'm convinced the balance is right..

[2007CSI]

I would go to a Discount Tire store and get an opinion from them. I even took mine there when it was new and bought the "certificates" from them for road hazard coverage. They have found many issues over the years with tires that the dealer seemed to ignore. On my 2002 Avy, all of the steel belts started poking out of the sidewalls at about 16,000 miles and they got me some credit from Goodyear that I put towards Michelins. In any case, an independent opinion may be more useful at this point. 

[plutnicki]

I did have the tires balanced by a local tire shop (didn't think of buying a road hazard from them).  They found the dealer completely messed up and rebalanced everything.  So, I'm fairly certain the tires are now balanced right.

It's a wierd vibration, because it's not constant or steady, and really only occurs on older roads (fresh pavement is fine).

I've spoken to the dealership's GM about the fact that the couldn't balance a tire, and he's offered me that the next time I need work to call him personally to give them the chance to make it right.  Maybe I'll take him up on it.  I suppose the 2 remaining older tires (with the full 11k on them) could be bad, or could have been messed up by the poor balance for the first part of their life.

[2007CSI]

I had an allignment done a while back on another car and it kept pulling to the right. They checked the settings and even biased it a bit left and it still pulled to the right. The mechanics were baffled. The manager went out to the shop and swapped the left and right front tires to the opposite sides and it drove perfectly. Tires can be odd that way.

Belt shift. Still not an uncommon issue if tires are swapped side to side; especially if they've been run in one direction for quite awhile. Swapping them back usually fixes it, as it did with yours.

[Avalanchin_in_WV]

Had to have driver inside door handle replaced (chrome has seam at top that split and cut me several times).  Console cupholder replaced (friction tabs missing) and steering wheel out of alignment (they said this was by design and not a defect...)  Has anyone else heard the same?  I don't like the feeling that the airbag, were it to deploy, may not fully protect me and I certainly don't like sitting crooked in the seat just to be centered on the column.  Also, XM reception is poorer on AV on exact same stretches of road than aftermarket XM with the little magnetic antenna that came with it.  Also some problems with Onstar reception and cutting out, but I do live in WV, which is mountainous and would explain some of the reception problems, but not all.

Cheers,
Avalanchin_in_WV

[Rocky07]

Had my '07 LTZ since August 2006.  Now have 30,383 miles.  I guess one of the first assembled.  Several problems to report:

1. Vibrating driver's side mirror (mirror only, not housing) as reported by others-not yet fixed
2. Rear engine old seal leak....about to take it in for replacement
3. Torn shifter boot at 10K miles (my '02 did the same thing)-fixed
4. Nagging rocker arm tap or possible collapsed lifter.  Shows up on cooler/cold mornings.  Dealer refuses to get into it unless they hear it themselves.  Left it 3 times with them.  I have two 30+ second audio recordings that I have played for them.  I'm caught between The General's Warranty repair criteria and a Dealer who won't act.  Gonna jump some a---holes on this one soon!
5. XM Radio quits and all other Display and Communications features are also affected....OnStar, Phone, etc.  I have a written a blow-by-blow narrative regarding this entire experience that I gave the dealer.  OnStar has issued Trouble Reports on the matter on my behalf.  Dealer replaced the XM unit 3 weeks ago.  Problem remains and not yet resolved.  If someone else is experiencing these problems, I will be happy to post the narrative for your review, comparison, and use as needed.

Happy with the truck, love the ride, great MPGs, loads of features, unrivalled comfort.....but, very dissatisfied with the MX problems thus far and the (lack of) the dealer's concern and performance.   Driven nothing but Chevys since 1972 and this one has had more warranty issues than any other.

[DaMaine1]

Hey All,

I've had my '07 LTZ since December 2006 so far two major problems

1. Rear main oil seal leaked at 2400 miles- fixed
2.  Forward Sprag clutch went out at 28850 miles - Transmission rebuilt.

One more major problem and Japan here I come!

[Rocky07]

Yep....I know how you feel.  Frustrating...ain't it?    My '07 has had more irritating warranty issues than all of my previous Chevy trucks combined since my first in 1972.  If I don't get the dealer to agree to fix this tapping problem soon, I'm going to drive it up his backside where the sun doesn;t shine.  My rear main seal oil leak is very minor.  Just a slight residue showing up between oil changes with no drop on the dipstick.  I've been waiting to see if it would get worse over time.  With my dealer, it seems I need to push it in by hand to convince them something is wrong...

The General has the dealers hands tied behind their backs on warranty repair reimbursement that all of them have had training at the University of Excuses.

Not to    but,

My wife's Tahoe 07 LTZ 8k (same engine as AVA) has been returned for:
-Drivers mirror same as everybody else here.
-Rear defroster didn't work.
-Air bag sensor came on took it to the dealer and they said the sensor on the driver side floor was defective replaced it and no problem.
-Third row seats wouldn't stay down, dealership replaced both seats first set that came in were wrong color next set came in had a tear in one of the sides.  Mechanic took off bottom and switched them and problem solved.

[liftedlt2]

had mine in for
creaking weather stripping around all 4 doors
dash rattle
broken speaker
tire sensors (three times)
blown rear end
shifty mirrors on both sides

[brianm]

Here is my list now that I have just over 30k on it.  I am not impressed with all of the issues I have had.  Fortunately no ugly transmission issues.  I still love my Avy but am worried about issues after the 3/36 warranty.

-BCM update for phantom wipe
-E85 Update
-Battery rundown update
-Creaking noise from right side of hood at cowl
-Rattling instrument cluster
-Whining power steering pump (replaced entire pump)
-Front bumper popped out away from fender
-Twitching driver side mirror glass (adjusted multiple times entire mirror the replaced better now but still moves some)
-Window trim coming up after rolling windows down (been in once before, still happening in again now)
-Drivers side heated seat literally burning up the seat cushion
-Pinging just before switching from V4 to V8 (seems to happen in warmer weather, been to dealer twice and they cannot duplicate)

Only thing has been the aspirator for the auto climate control.  It is located right above the driver and was vibrating/rattling like crazy.  Fixed now. . .Much better

Same exact problem.  Im also on my second radio, about to be my third i think.  Here's my problem as posted in its own thread:

the main problem im having is my clock keeps deleting itself.  about three weeks ago it just vanished but the tab for it in the right hand corner was still there, just empty.  replaced my radio yesterday under dealerships advice.  everything works, set the correct time (in the parking lot of course), couple hours later- no clock, no tab.  cant find it under menu or anything.  when i turn it off, the screen goes completely blank.  it used to be blank with only the time showing in the center.  now nothing.  disconnect the batter and still no clock.  i dont know what to do.  any ideas?

p.s. i have the nav/radio

[k15goose]

found answer to the clock problem and posted in:

[champ150]

in for ;
bad wipers/washers- they ice up severely- did not/could not fix
rear main engine seal at 6700 miles
dash rattle
rear window fell apart the 1st week
snow and ice collected on rr tail light wires and pulled them out of tail light
wish I would have kept the 04 Silverado, that was never in!
defrosters do not keep ice and snow from building up the bottom 6 inches  of the windshield

[plwtwo]

   LTZ 1654 miles in for Bad Shifts/slipping/sticking ..They claimed nothing wrong,yet kept it 4 days....and it doesn't do it anymore...  Fluid smelt burnt when it was dropped off and was really dark...checked it in their parking lot and it wasn't dark anymore and smelt freah/normal.  They say however they didn't change it..  I do know the first 10 hours they had it all they did was hook it to the PCM reader...
  They blamed the problems on the Cold Air Intake.

[07Z71]

On my list @ 21000 miles.  .  .  .  .  .  .  .  .  .  Dash rattle and Nav system problem.    Nav screen goes blank, resets area of country for searches and looses 1 hour of time on the clock.    Pretty happy other than those items and the fact that I have 51 payments left.  

[malligood50]

570 miles - mine goes in Tuesday for Gatorback

[k15goose]

does it need gatorback?  and youre getting this under warranty?

[Captn Morgan]

Good topic!

- 4WD issue.  I believe it stayed stuck in 4WD for a bit.  They replaced a solenoid or something, can't remember exactly what it was right now.  That was probably around 10-12K miles.
- Transmission/Sprag issue - just like a lot of other, suffered this trans failure at 20K miles, and they had to rebuild it.

Some issues that I still need to bring it in for...
- IP message area displays "Service 4WD System" somtimes
- Key Fobs don't work after vehicle sits for a bit, or after I manually unlock the doors
- Cargo covers don't lock (I saw this in some else's reply here and realized I have that issue.  Thought maybe I'm doing something wrong)

[diablo078]

Just took it today, heres the list: Check Engine light  bad O2, chrome on inside door handle peeling off, odor in the AC system, Gatorback coating as per TSB, Front Fasica being replaced due to having cracks under both headlights, transmission downshifting problem, also before had front brakes done with upgraded pads per TSB. thats all i had done so far.

[obe-kenobe]

I have an 08.  I noticed some oil leaks at 1400miles and finally took it in a week ago.

- oil leak from front engine galley plug.  They also added dye to the engine oil as
   the rear main seal might be leaking as well.  (knock on wood, its dry so far)
- rear passenger side storage box hinge was rusted due to paint chipped.
  Hinge was replaced.
- the bed weather seals for the 3 bed panels were not aligned right.  They
  replaced the weather seals on both sides.  The seals go all the way around
  the rear window.  They had to take apart both c-pillars and the 3rd brake
  light panels.

Second post in this thread.

07 - 5.3 - 2wd - 28,600 miles

Today I got a new water pump and the front rotors resurfaced.

That extended warranty offer from GM is starting to look like more of a necessity than a luxury.

[Avalanchin_in_WV]

21K on my Avy now and the protective coating on the grill surround and front bumper is peeling like a bad sunburn.  Anyone else see this with the '07?  If so, what's GM doing to correct it?

[Rocky07]

Should be under warranty.  If you run into problems, ask the dealer to show you where it says on the "Options" list where it says, "Peeling Chrome Trim Feature"

[CHEQ6]

I just got mine back today.

Bad alternator for P0700 and P0977 codes.
Bad Rainsense sensor.
Bad key fob.

I'd have to look at the history (I have it) from the previous owner for any other repairs.

[AV-03/07]

I thought about starting a new thread, but i guess i will end my own.

Problems

1, Tranny-Lousy-after several visits and  finally a total rebuild at 9k, the tranny shifted better but still slipped intermittently between 2nd & 3rd, and after the rebuild it started leaking fluid between TC and front pump!  Never fixed!

2, Engine-Oil leaks-after several visits & several oil leaks fixed one remained at the back of block (can you say tranny removal-AGAIN)  Never fixed!

3, Engine-Lifter noise-random at first then constant at the end, Never fixed! A bad case of cold knock-noticeable below 30.  worse gas mileage 2/5 less MPG depending on the drive than my 03 AV

4, Front and Rear facia-Damaged-while pushing vehicle in and out of repair bay for tranny removal and replacement.  FORCED to fix! 

5, DIC-Service STBTK/Service 4X4/Service PKNG ASSIST.  error messages would come and go-mostley in humid and rain conditions.  no codes stored/no resolution, Never fixed!  

6, Power Steering Rack-leaking-after several visits, Two racks and then a
rebuild of the new (replacement) rack.  Fixed.

Strike Three.  its gone

P.S.  I never had the dead battery/remote fob issue though,  that would have been a real bummer.

buy back, or you sold it?

[AV-03/07]

buy back, or you sold it?

 

Would have liked a buy back, but they considered my problems average for the vehicle.

Would have never sold it privately.

Would have traded it in (at my chevy dealer) but they low balled the AV big time,  25k (max) for an LT2 with 20s with only 19k-Not my dealer any more

Traded in for an 08 F-150 FX4 and they gave me the best trade 29k!

don't blame you for not using them anymore 
hopefully you'll have better luck with the new ride

[AV-03/07]

Thanks,  So far so good.

I know every now and then a troubled one gets out, I just can't believe the difference between my 07 and 03-which was never at the dealer!

[vrf201]

Current list:

1. One new body mount, two front struts according to GM.
2. Transmission repaired twice at 26,000 miles
3. One new front head light assembly.

[Denman]

AV back in the dealership for Service Airbag message issue got a rental car at least, also looks like they will have it through the labor day weekend:(

[msdinsp]

Getting new wheels for mine, looks like the clear coat is starting to seperate.

[OhOneWS6]

Took my 07 LT2 in today for a number of issues. The most annoying issues happen when I try to start the truck.

(1) When you are attempting to start the truck and you release the key, the engine will start but the starter stays engaged.  The only way to disengage the starter is to turn the key back to the off position.  At first I thought the key cylinder itself was actually sticking in the start position and not returning to the run position after releasing the key.  This however, is not the case.

(2) When you are attempting to start the truck it takes several seconds for the truck to start.  This reminds me of my old carbureted 72 Chevy Cheyenne Super when it has been sitting for a few weeks without starting it.

Of course both issues are intermittent and the dealer can not duplicate.  The dealer is going to replace the fuel pump and the injectors.  They did not have the injectors in stock so I have to take it back next week sometime.

The other issues were rattling glove box door, sticky ac vent dial in the center vent, pop under the drivers floor board and really crappy gas mileage.  (~10.3 on E85, ~13.8 on Gas)

There are some threads about this problem in this forum somewhere. GM made it so the starter keeps cranking until the computer thinks the engine is running. If a sensor is not reading that the engine is running, it just keeps cranking. Like I was saying, someone else went through this a while back - do a search and you will find the answer.

Check out the thread that SNI+PER created.  He describes the same problem.  Dealer changed his injectors....wasn't the problem.  Personally, I believe this issue and others described elsewhere as a starter switch issue.

[AVundecided]

Well until yesterday mine hadn't been to the shop...But now its for something major...the Tranmission went out or is going out.  That really sucks.  I LOVED my Avalanche up until now.  Now I'm scared they won't fix it right and I will be stuck with a lemon.  We will see.  The dealer did come and tow it and they are offering me a rental car.
Other than this a few rattles here and there but nothing really worth taking in for.

[CntrySngr72]

Getting new wheels for mine, looks like the clear coat is starting to seperate.

How did you swing that one?  I think mine are doing this too!  Wonder if I can have mine replaced under warranty when I take it in for the front bumper clearcoat issue.

[k15goose]

I don't think you get your wheels replaced.  At least, you're not supposed to.  The dealership is supposed to send them off and they resurface them.  About a two week process, I'm told.  If I'm wrong let me know...

[jtdchevy]

So far went back for the heated wiper recall, fuel gauge sensor, oil leak

[Jackdiesel]

Other than the factory recalls

-driver seat heater
-back side of passenger seat clips broken
-steering wheel coating peeled off
-gm headrest dvd has engine hum when listening over the external speakers (still not fixed)
-rear window out of align (leaking)
-front driver sensor
-passenger seat lever knob (to move seat)
-shakes bad over 155 mph   (just kidding)

I bought it used w/29k on it. Not sure what was done before I bought it. Motor and tranny good so far. Think I gunna hold my breath on that though. (Still love this truck anyway).

[Denman]

Avalanche is in the shop again this time no 36,000 warranty... but I did purchase the gmpp major guard and hopefully it covers a bad steering gear... that is the diagnosis

Note: GMPP covered steering gear replacement otherwise it would have been a grand to fix out of pocket..

[Aussie Red]

Not much problem with the Pearl.

Service air bag light
Maf sensor ( turns out did not need to be replaced)
Fuel pump


So overall am quite happy with him.

[jtdchevy]

Lets see. 1. Intake manifold gasket  2.pcm fried. 3. transmission wire harness fried.  4. vent valve Solenoid  5.fuel level sensor 6.fuel pump.   1 and.2 covered under warranty.  3,4,5,6 wallet warranty covered those. 

[Rocky07]

RockyII going in for shocks on all four corners.  No warranty on this repair at 71K miles.  The LTZ has the electronic monitoring up front and air in the rear.  This visit is going to be expensive.....but, my company pays the tab!

Anyone notice how much more expensive GM repairs are since the Bankruptsy?  Government Motors repair costs should be an indication of how expensive a national healthcare program will be.

[wrpfctr7]

Took my 2007 Av in for a new fuel pump.  It was covered under warrenty, so that's a good thing!

[1Fastrider]

Had my spare tire hoist assembly replaced

[Rocky07]

Got all four new shocks yesterday.  Feels like a brand-new AV again.  What a LTZ ride!........

[05sunburst]

08 LTZ. 11,600 miles. Finally front rotors replaced after being resurfaced twice. Then one day all of my electronic were going crazy. Lights flashing, windows opening and closing, dash lighting up like a xmas tree. It had to be towed to dealer. Drum roll, the culprit was a loose battery cable.  :E:Dealer blamed factory because their a TBS for it

[old skool]

24,000 - 25,000 miles...No problems. Knock on wood. 

[ttamrettus]

2007 Avy 4x4 Z71, 54,000 miles, FUEL PUMP BAD.   

[old skool]

24,000 - 25,000 miles...No problems. Knock on wood. 

Spoke too soon...factory battery went out today...new replacement from AutoZone, $166.00. 

[05sunburst]

Brakes   Its has gone back to dealer seven time for this same issue. Vibration, pulsation, and a thump thump as the brakes are applied. It all started at 2,000 miles and now the truck has 12,316. the dealer finally replaced the front rotors two weeks ago after I came in for the fifth time and having them cut twice. But I still have the thump thump and pulsation. I'm so fed up. I have started the NJ lemon- law process. I'm sick of this issue. Gm better take this truck back.
