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.

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.

The spare tire release cable on my 2002 Chevrolet Trailblazer became twisted and could have broke releasing the spare tire as the vehicle drove down the road. The spare tire had never been removed from compartment and so it would appear to be a manufacturer defect.

The spare tire hoist cable system tangled or jammed and would not allow the spare to lower further or raise. I had to use rope to tie the spare tire to the frame to make sure it would not fall down while I was driving which clearly could have thrown the back of the vehicle upward. The dealer had to cut the cable and replace the entire hoist assembly: $176.54. The hoist had been used successfully on three other occasions.

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.

It appears the truck is suffering from a major computer defect. With all fuses in tact, many functions no longer work (remote access, radio functions after ignition turn off, automatic volume increase on radio when accelerating). Additionally, the 4X4 torque converter switch does not light up and appears to be nonfunctional, the airconditioning quits and after alleged repair, stays on all the time regardless if set to air or vent, the rear hatch is defective and can't be opened, the tail lights have burnt out three times and two headlighrs have burnt out.

This vehicle is equipped with "memory" mirrors that are supposed to return to the last stored position when the remote keyless entry is used. Instead they drive to an extreme position, make a loud clicking noise, and stay that way. Many times I've been trying to make a lane change and found the mirrors pointing toward the pavement. The manufacturer is aware of the defect and has fixed it in the 2003 model. However, they refuse to fix my vehicle. This problem exists in all 2002 Trailblazers and GMC Envoy. There is an internal service bulletin at Chevrolet that explains it.

My vehicle has a squeek sound in it. The dealer has replaced everything possible under the vehicle and is now at a loss as to what the problem could be. I am wondering what my next step is to do. This is an ongoing problem since I purchased this vehicle. It has been to the shop a dozen times or so for this.

Upon starting vehicle, the electrical system malfunctioned, causing the headlights, radio, and the dashboard lights to short out. This happened several times. The consumer had taken the vehicle to the dealer and they changed the sensors, however it did not solve the problem. There was noise in the steering wheel. The consumer was told that the problem was a characteristic. The hatch lock did not work, and the rear windshield wiper did not work. The oxygen sensor was changed twice along with the seat belt switch, the key lock on the driver door, battery, and the wiring harness. Also the cup holder broke.

Wiring harness burned up. Caused damage to control panel, dash, computer system. Entire vehicle gutted to replace wiring. A door panel was broken in process. Several rattles now exist. We were told there was no way of knowing if electrical problem would occur again. GM agreed for repurchase. However, they delayed procedure so that 0% financing can not apply. Also wanted us to pay out of pocket, buy back amount said we would be reimburced, but would not put it in writing.

Not your ordinary safety defect but an unsafe condition nonetheless. I live in Arizona, a place that tends to get a little warm. When the vehicle heat soaks in the sun the remote keyless entry fails.the dealer has replaced the main receiver board and the ( 2 ) entry transmitters with no effect other than modifying the failure characteristics. The ( 2 ) key transmitters also do not operate the entry system in an identical manner. One will operate all entry system functions, the other ( transmitter #2 ) will not. This will create a severe problem if immediate access is required to the vehicle and you cannot rely on the system to have the vehicle unlocked when you get to it. My brother, also the owner of a 2002 Trailblazer, is complaining of the same problem.
