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.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 29,000 miles


Left brake light shorted out at 29,000 miles. Service manager at dealership had indicated that this was very common in 2002 Trailblazer. If I didn't have someone behind me nice enough to tell me, it could have been a problem. Dealer indicated some type of circuit board needed to be replaced.

problem #2

Apr 202003

Trailblazer 6-cyl

  • Automatic transmission
  • 7,900 miles
Both left and right brake lights failed to operate. Vehicle was bought new 7.5 months ago and has about 8000 miles. Found the fuses good and the light bulb filaments good. While checking the light bulbs, I discovered that moving them slightly in the out direction, the lights would come on. Upon examination, it appears the metal connection tabs within light socket and/or the bulb wire- type connections may have been damaged by heat. There is some discoloration on both. Although the bulbs are not burned out, they will not work when fully seated into the socket - there is no electrical connection. They do work when pulled slightly out. I installed new bulbs which do work when fully seated. I now wonder how long it will be before this problem occurs again. I believe there may a design defect with either the socket or the bulb, where heat buildup in the connection was not taken into account.

Trailblazer 4WD

  • miles
Failure occurred in traffic in St. Louis, mo. A large truck following behind had to brake abruptly to avoid rear ending my vehicle. The other driver was kind enough to tell me that my brake lights were not working. I took the vehicle to the dealership and had them repaired. The service man told me that they have had to replace several of the switches in the steering column. I believe the company has a defective part if the service people are noticint a trend. I contacted cheverolet and the "started a file".
