This is the E-mail I sent to GM regarding the problem with the back seat and how I feel this is a safety issue. They did not respond to my E-mail so by the 8th day I called and they said they closed the case based on what the dealer said, "condition does not represent a safety hazard." I strongly disagreed and pursued it further getting the same answer. Here is the E-mail: I have a 2007 Sierra GMC with a back seat that has movement (play) in it due to what GM calls a "rattle clip" breaking. I questioned the dealership when taking the vehicle in for a different repair and was told that it was just a rattle clip. I have called GM regarding the safety issue and was given an authorization for a covered diagnostic on the truck. Again, the dealership said, "found 2 seat back rattle clips broken. Condition does not represent a safety hazard." I declined the repair based on the fact there is no known cause for the failure of these clips except for the simple fact they are cheap plastic. I do not feel replacing a plastic clip with another plastic clip will fix the problem. It will only be a matter of time before they fail and the seat has play in it. I question if they would even hold in the event of an automobile accident. When strapping in a child's car seat there is to be no movement in it in case of an accident for obvious safety reasons. I do not see how a back seat that has a 1 1/2 inch or more of play in it is not considered a safety issue. I have a video I would like to E-mail you so you can determine this for yourself. I am requesting they address this safety issue so my family and any other passengers can be safe while riding in my GMC. I would like to point out although they named this part a "rattle clip" it serve more of a purpose than to just stop a rattle nose. It secures the back of the seat to the frame of the truck so there is no movement.

The contact owns a 2007 GMC Sierra 1500(na). The original seat covers were replaced because they absorbed lint very rapidly. The vehicle was taken to the dealer, and replacement covers were installed. The replacement mats exhibited the same failure. The manufacturer was notified, but no assistance was provided. The failure mileage was 2,000. The current mileage was 24,000.

Cloth seats accumulate pollen and dust creating a potentially dangerous problem for people with breathing conditions - this problem is acknowledged by GM via a tsb numbered subject: Excessive lint accumulation on cloth seats (replace seat covers) #07-08-50-018 - (08/28/2007) and then again with document id# 2023269. I know this typically does not qualify as a safety concern but the situation is relatively extreme to the point where after a while that using a vacuum cleaner is no longer effective for individuals with breathing problems.
