1) ABS and E-brake light continually come on; unsure if ABS system is functional; I have had the computer tested and it returned no faults 2) side windows work intermittently; no explanation; windows will not roll down for days at a time and then they work fine for days at a time 3) sunroof no longer functional; Chevy dealer said the "heat" warped the internal parts and they broke as I rolled it back; weather was mild and the breakage happened at 0500 in the am; I don't believe it was heat related 4) rear of vehicle is has drastically fallen below the front; I have no explanation as to why; it looks as if the vehicle front suspension was raised and the rear was lowered; drives fine, but feels unsafe all of the above happened shortly after the warranty expired, between 40000-50000 miles.

The parking brake falls to the floor when the driver presses down on it, causing the vehicle to move slightly. The consumer is concerned that the vehicle is not secure, and could cause it to roll and cause an accident. The parking brakes had to be adjusted 3 times in 2 years. The brake would eventually go down to the floor board again. The consumer believes there is either a design flaw or the parts were defective at the time of assembly. The last adjustment, the parking brake was within one inch of the floor board.

Parking brake does not hold. Adjustments made starting at 20000 miles and three other services. Now at 38000 miles we are told that the brake needs to be replaced. The brake has never held well and now not at all. I have noted many others with the same experience in online chat rooms. This is a real problem, GM is aware of it and it is dangerous.
