CarComplaints.com Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

I brought this car on August 14, 2004. At 2 months the vehicle stop working. I call the dealership and told them what was happening. They told me that it was a battery problem and the insurance I had got with them did not cover it. So then I decided to purchase a insurance that would cover that. They charged me one thousand dollars. Later they called me to tell me that I did not qualified for the insurance. They didn't return me the one thousand dollars I had gave them. Since the beginning the sales person lied to me. He told me that the vehicle was 2003 but it is really a 2002. The transmission to my vehicle does not work. I want to cancel the purchase of this car.

Problems with air bag dash light, fast engine idle, air conditioner, rear hatch inner strap broke, etc... the airbag light was intermittent. The sir module was replaced, and there was poor terminal connection at the sir wiring harness, and was traced/repaired on the left side impact connector and the codes were cleared. The engine idled fast(especially at start up, and the fuel mileage was 13 mpg. The results of the evaluation and repairs were: Passenger impact connector was loose(repositioned/connected), idle within specifics, the emblem had fallen off, the rear hatch inner strap had broken, the transmission seemed to take long to shift into gear(happened sometimes when cold), and the PCM needed to be reprogrammed(J6355 power train controller PCM). There was a thumping sound in the rear differential when shifted, the A/C would blow out cold air when the A/C indicator was off, hot air would come out of the defroster area on the dash when the indicator was set for heater on the floor, the engine made a tapping sound, the lift gate weather strip had come apart, and the battery kept losing charge(3 occurrences).
