09 LT1, Drivers electric seat rocks back and then forward when accelarating and stoping it doesnt move much but i can feel it. I weight 240 and I like the front of the bottom cushion raised high, my wife does not experience the same problem when she drives. Dealers says it's normal anybody else have this problem? ???

It's not normal; I had the seat tracks replaced on my Acadia for the same condition; I would go back and ask your dealer if there are any TSB's for this condition

Does not happen to me on my LT1 and I'm 230lbs.

This was a hit and miss issue on 07's and 08's

They replaced our seat back assembly for movement, but the whole seat didn't move, just the seat back. I noticed it before we got rear ended, but it was slightly worse after getting rear ended. My dealership replaced it with no question (although it did take them almost 3 weeks to get the part).

I kind of blame it on a 3 year old that sits behind the seat and likes to push on the seat with his feet, but we'll see if this one gets loose.

My '09 seat was squeaking extremely loudly under the same conditions once. I tried to grease it to fix it but couldn't. My dealer fixed it easily and under warranty.
