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.

Print this page 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.

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.

In November of 2002, jn automotive has reversed the odometer on my vehicle and I believe they are in violation of the federal odometer law. I just want to find some resources that will help me resolve this situation.

My vehicle has been in the shop for these reasons and more. Faulty back light- dvd systems. On top of all these it has had three recalls in the nine months I've owned it. Bought it new!
