Nope, mine only shifts when my wife mashes her unlock button while we're getting in. Instant lack of leg-room.

Mine does not shift...although it sqeaks quite a bit when my bodyweight shift. Of course I push the scales at about 275 so what can you do.

Nope my av does not have this problem

Mine does not shift. However, it is very uncomfortable and without an orthopedic device, is quite painful.

I've never noticed this.

Mine shifts slightly. Planning to check bolts to see if loose. Just noticed within last 1000 miles. Total miles 35,000.

yeah i noticed it this morning. i saw this post and thought i would start paying attention to it. sure enough it shifts when i start to pull off from a stop.

That is exactly what happens to me. The dealer has checked twice and says it is bolted and torqued to factory specs.

It almost feels like the base alone shifts from the rear right corner? My observation!

I sometimes feel just a slight little movement when starting from a stop or hitting the brakes. In my case, it doesn't feel like the whole seat moves, just the backrest. It's as if there is just the slightest amount of play in the reclining latch.

What seats do you who it feels like it is moving a bit have?

Maybe it is slack in the motorized mechanizm thingys?

I had some old crappy cars where the seat bolts tight but the frame underneath had slop in it

A very good question, why didn't I think of that! D'oh!

Anybody who has felt anything, post the details of your seats, and let's see if we can find a pattern.

I have the '02 cloth buckets, and it feels like it might be in the manual recline mechanism.

I have leather captins chairs!
With heated seats and all power.

I have full power seats with butt warmers and them things are tight and do not move...................well except when I hit the button thingys.....

 

[02-Z66]

good question. not sure if it is the right base or recline pivot point. but, it is definitely in one of those areas.

I have the cloth buckets and it seems like the little movement comes from the left side of the seat moving back. It "MAY" be in the power slide rail

 

[02-Z66]

still trying to decide where this movement is from. i will try again today while fixing the material on the front of the drivers seat. it comes undone whenever i sit on it. has anyone come up with a solution yet? btw, i have the cloth seats.

MY 2002 AV DOES NOT HAVE THIS PROBLEM HOWEVER I HAD A 1998 GMC YUKON AND IT HAD THE SAME PROBLEM.I TOOK IT TO THE DEALER SEVERAL TIMES AND THE PROBLEM WAS NEVER SOLVED.THEY REPLACED A PIECE CALLED A SEAT RISER TWICE AND THE PROBLEM WAS STILL THERE.

 

[TLB]

I don't notice any movement in my seat of my 03 AV and didn't see any in the 02 AV that I had before, But I had some in the 97 Silverado before my AV's.

If all of the mounting bolts are tight, any movement in the seats is likely to come from the recliner mechanism first, then from the adjusters be they manual or power.

The recliners have more tolerance built into them due to the fact they pivot on bushings, which are typically plastic. Power adjusters will be more prone to movement than manual because they are more complicated and have more pivot points.

It will all boil down to the luck of the draw. If you happen to get a seat that was built with components that are at the outer limits of the design specifications, it will have some slop in it. Based on my experience building OEM seats for the past 17 years, this only happens very occasionally.

I had shifting seats on my suburban. It is the slop in the recline worm gear that causes this problem... I am assuming that GM hasn't improved this mechanism and is using the same thing in the AV. My dealership changed both the drivers and the passengers in the burb. So far...sooo good with my av.
