Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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.

The contact owns a 2002 Chevrolet Trailblazer. The contact stated that the steering wheel cover that covers the air bag appeared to be cracking. On February 11, 2009, the air bag warning indicator illuminated. The dealer will be notified because the contact feels that this is a serious safety hazard.

2002 Chevrolet Trailblazer with problems with car radio customer wants reimbursement for repairs* some type of electrical problem caused a loud pop to come through the speakers. The caused the radio to short out and the speakers to blow. The radio and speakers had been replaced several times. The amplifier also had to be replaced. The vehicle has been taken to the dealer on numerous occasions but they have been unable to correct the problem. The middle seat belt in the second row locked up as soon as it was fastened into the buckle. When the defroster was used the consumer heard a clicking noise. The dealer replaced the mode actuator and mode valve per tsb 04-01-38-002. The quarter panel on the roof seam sealer cracked and was rusted. The pull down strap on the rear hatch broke. The sway bar broke. A grinding noise was heard coming from the left front wheel when making sharp left turn. The dealer determined that suspension was misaligned and caused shield to touch rotor. The instrument cluster gauge was inoperative. The rear wiper did not touch the rear windshield. There was a high pitched noise coming from the right side tire whenever in motion. The dealer indicated it was improperly sealed.

Have had many of the problems I read on posted complaints: New engine required within nine months-one year of owning new vehicle, inside driver door panel replaced three times, change oil and service engine lights staying on, hood not closing properly, back glass needing replacement, fabric problems in back seat, etc., etc. And this morning it is a $200 problem with the headlight switch. Too many things to even remember or name, but Chevy has a pretty thick file on me and my vehicle.

Noises coming from underneath the SUV, check engine light constantly came on and one night I was going around 55 mph my 15 yr old daughter, we heard a loud pop it sound like we had hit something in the road so I stop to see what it was, we saw nothing but the squeaking sound from under the SUV got louder some day later jumped in the car started the car and there was that loud sound again only this time the SUV would not move in reverse I could hear some spinning like noise so I took it to a shop and I was told that the transmission was striped out in reverse, and that some shaft had broken or something, the mechanic also told me that he had several people come in with the same problem the same model Trailblazer 2002 what hurt me so bad is this was my first brand new car, I only had it for two years, and if I every buy another car it want be from GM, I also had problems with my tailgate lamps, windshield wipers, steering column.

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).
