This vehicule has a drivers power seat, upon pulling out onto the road the seat broke loose from its mount. I did have both hands on the steering wheel at the time and was able to keep control of the vehicule as it lifted from the front left mounting bracket. After looking at the seat I discovered that the seat mounting bracket on the left side of the seat is bolted into thin sheet metal to the seat frame and not into the seat frame rail. This appears to be a design problem since the passenger seat frame rails are bolted to the seat brackets as should be. I contacted the dealer and he said they would fix it, but that I would have to pay for the new seat frame and labor as a normal service call. Contacted the customer assistance line and filed a report and was told it would be put on file as a complaint file # C01348445, have not heard anything in a week. I will be fixing the seat my self in the near future by taking 3/16 X 1 1/2 flat bar and bolting it to the seat support brackets and bolting the seat frame to the flat bar. Will try to take pictures of the problem before it is fixed and after it is fixed, anyway the damage part will still be there as the flat bar will just give it strength. What it appears to look like is the vehicule has a full size seat installed on support brackets made for a S10 size vehicule. If my seat broke I am sure there are others that have the same problem or will have the same problem as it is just a matter of time, they may not be so lucky as I was.

Driver's seat broke 3 times under warranty & was repaired. It has broken 2 or 3 times since and been repaired at owner's expense. Dealer now says owner needs to buy a new seat. We feel General Motors is responsible and should have replaced the seat back when it was under warranty. This seat continue to break under normal driving conditions. What would have happened in a collision" what will happen in a collision" the seat belt and air bags are useless if the seat breaks! the dealer says it is a piece of alloy metal on the seat brace that continues to break. We understand that several GM vehicles have had this problem, but there has been no recall. We went to the dealership in good faith while it was under warranty and were told the problem was fixed, more than once. Now they want us to buy a $500 seat to fix a problem we feel they are responsible for.

- Ames, IA, USA

Both passabger and driver seat frames/tracks have failed. Seats rock excessively and passanger seat somtimes releases and slides foward. 3 friends that have Chevy Tahoe's have had their seat frames replaced several times (one person has had 6 new seats) I believe that this amount of failures constitutes a manufacturer defect and is unquestionably a safety hazard (passanger seat sliding foward when brakes are applied abruptly, I almost sent my girlfriend through the front window). I am only 175lbs and my seats frames have no reason to fail. Please check any dealer repair history for this make and you may find an extraordinary amout of failures.

Vehicle experiencing problem with seat anchor torn from the bracket; causing driver's seat to rock back and forth which can lead to an loss of control if seat rocks too far back. Requesting NHTSA to look into this matter.

- Long Valley, NJ, USA

Drivers seat is loose causing slight rocking motion and clunking noise when stopping / starting. This seems common in 95 - 9? full size chev / GMC SUV's. I have read many NHTSA customer complaints for this same problem - some resulting in failure of the seat to remain upright and resulting in a dangerous situation. I do not believe I should have to pay to repair this defect which I hear may cost as much as $1,000 in parts and labor. This is an obvious and dangerous safety defect which requires correction by the manufacturer.
