I have already contacted the BBB, here is the list of problems I have had with the truck to date.
Current vehicle problems are preceeded by an "*".
How much oil consumption? Do you have any smoke on start up? Do you have dieseling on start up or bad piston slap? When did the oil consumption start? There are a couple of TSB's specific to this issue.
You've noted problems with your horn below with fuses blowing out. I've run through the list but it does seem you have an electrical problem in your Avalanche. Can you explain pulsating?
*condensation in headlights
*condensation in foglights
There is a TSB specifically on this issue. Look, if you take a clean dry glass, seal it tight with plastic wrap and sit out in the sun SOME condensation is going to form. With the basic end of seal beamed headlights light condensation is normal. The TSB covers this. Light condensation is described as water droplets smaller than 1 MM - a light mist. If you have large drops or standing water than yes you have a problem and the TSB clearly states the housings should be replaced. If you have just the light misting with tiny little drops this is normal. Switching to a "hotter" bulb, especially in the foglights will be a big help. I recommend the 899 or 885 bulbs. 899 if you live in an area with a lot of fog, snow, smoke or rain, 885 if you want more of a driving light.
Under what circumstances? My 4WD whines too if I'm going over 55 MPH, but if conditions warrant 4WD or Auto Trac you probably shouldn't be going 60 or 65 MPH. When are you using the Auto Trac and the 4WD? BTW - Auto Trac is not the same as AWD - but it is pretty darn close. Also although there is no TSB on the issue it is established that the quality of the front differentials leave a lot to be desired. The odd thing is a failed differential because of the drive line design can manifest itself in many different ways. As a matter of fact a combination of problems you outline when combined all point to a differential problem.
This actually may not be an Auto Trac issue but a transmission issue. If memory serves me right there is a TSB on this issue. I know that under cold conditions on very rare occassions when I go into reverse first thing in the morning there is a clunk but not something frightening. I also know that according to the owners manual the Avalanche does funky things on cold starts (and I mean that in a positive sense) so that the engine and transmission will warm up faster. However if you're getting a clunk on start up everytime in Auto Trac the two questions I have are why are you in Auto Trac? Secondarially it once again points to a failed differential.
horns failed(kept blowing fuses), almost causing 3 accidents,
How has this almost caused three accidents? Of the problems you've outlined this tied with the pulsating dash lights points to some sort of electrical problem under the dash. Of all the issues you list, this is the second biggest IMHO.
*Anti freeze leak on side of motor
This IMHO could indicate along with the oil burning the most serious problem. Anti freeze leak plus oil burning equals bad head gasket in my book, but there could be other issues. Are there any signs that oil has contaminated the coolant or vice versa? Do you smell anti freeze from your EXHAUST (of course if it's leaking you'll smell it off the manifold).
*Occasional popping noise from steering wheel while turning
Can you say bad differential. Your complaints on the 4WD system, start off and the popping on steering all point to a bad front or rear differential. Not to be critical but if you've been using Auto Trac or 4WD on clean dry pavement for a while that is a major "no no" in a part-time 4WD system. It will eat those differentials alive in no time.
*Windshield rattles on highway
Well established issue with more than one TSB. Rare on models that don't have a bug shield installed, quite common on those that do. Can manifest itself on non-bug shield equipped Avalanches (and Tahoes, Suburbans, Silverados) when there is a cross wind. Willing to bet it starts up above 50 MPH. Your windshield IS NOT rattling on the highway. The outer trim is. The fix is documented in a TSB...further how to fix it yourself for under 5 bucks and under 30 minutes is outlined on this site in the Fun Stuff section - March 2002 issue of CAFCNA Magazine. If you have a bugshield that the dealer installed - shame on the dealer for not doing the tape.
Alignment off on delivery , dealer notified on test drive
This is also a well established issue. When the Avalanche is cranked down on the trucks for delivery the suspension can be pulled out of alignment. The dealer will give you a courtesy alignment at no charge from 500 to 7,500 miles. The other possibility is although the OEM GoodYear tires have come a long way in quality, they aren't the best and you can have a tire out of round or with belt issues. I had to have the dealer cross rotate my tires at 1,250 miles on my Avalanche because it was pulling right. After that there were no issues.
*Body rattles when door is closed
Where is it rattling? What do you mean by the body rattling? When does it rattle? At idle? When driving all the time? Driving on smooth pavement? Rough pavement? Only when you hit a bump? Is it coming from "the body" or is a trim issue?
I know some are very minor, its just to prove a point that many minor problems = a big problem for me, Thanks for the advise.

Frank,
Honestly based on the list of complaints above it sounds like the issues you are having are far more related to an unresponsive dealer than your Avalanche. Are you having some worse than average luck with a number of documented issues. Absolutely. However as I noted above there are TSB's on many of your complaints, and the combined complaints on steering and transmission all point to a bad differential, which is also a known issue. It was known enough that the General made changes to the differentials up front on the 2003 models. If you have a locking rear-end the Eaton differential is an awesome piece of hardware.
It doesn't appear to me, but I'm not lawyer that you have a lemon. It does appear to me that because the dealer has not addressed some glaring issues your vision is a bit tainted on your Avalanche and what is a real problem and what is the way things are.
Seriously, I would take a few deep breaths first. Second, if you have OnStar push the button and talk to customer service. I had to do that once with one small problem with my Avalanche and it was fixed so fast I was shocked. Heck they even called me back to follow up that I was satisfied.
Keep us posted and if you want my help on this I'm willing to assist. Just take a few deep breaths. Once you get the above addressed I'm sure you'll be happy. Again, of all the issues above the leaking anti-freeze is the one I'd be jumping up and down over - the rest is easily fixed if you have a dealer that even remotely gives a poop.
