Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Have been having major trouble with the front end. Had it checked multiple times at the dealer and at a local mechanics shop and the ball joints and bushings had to be replaced. Even the the warranty was finished, the dealer did not charge me for this, but unfortunately I thought that this would take care of the noise on the front end, but it is still there!! Also yesterday, april 24, 2007, I had to have the fan clutch replaced. This vehicle only has 35,000 miles. …”

“The taillights are delayed when needing to turn on. If you apply the brake, blinker or place vehicle in reverse, the lights will not come on until a few seconds have passed. Also condensation builds up on the inside lens. It happens ever time I drive or use the vehicle. A previous recall on the taillights did not cover the delay or condensation according to the dealer and GM. So far I have not taken any corrective steps, I am going to try replacing the assembly and hope that resolves it. The light is not cracked or damaged in any way, and vehicle has never been in an accident.”

NHTSA complaint #10272536, filed 2009-06, 92,000 miles

“This problem concerns a repeated lighting systems failure. This incident occurred when I was notified by another motorist that when I had the brakes on while stopped at a stop light that both the left and right tail stop lamps were not lit although the center high mounted stop lamp did light to indicate the brakes were on. I had had to have both of these lamps replaced only about 3 months ago when they both burned out within a short period of time, perhaps simultaneously as they might have last week. …”

“I have a 2002 trailblazer with multiple taillight / brake light failures. The dealership has resolved my problem, however I thought this information might be helpful to your open investigation. In november 03 my brake lights failed and my dealership replaced the bulbs under my then existing warranty. Again, in january, they failed again and I took the vehicle in to have the bulbs replaced. While sitting at the counter, I was speaking to a man behind the parts counter and explaining my problem to him. I hadn't finished explaining when he told me I must have a trailblazer. …”

“Pulled into driveway, lights would not go off, a few minutes later smoke was coming out from under hood and it smelled like burning plastic. Popped hood and fuse block and relay we smoking and melting! Got fire extinguished and pulled the head light relay switch, but it had melted through the block!!!!”
