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.

I own a 2002 trail Blazer ext. I bought it brand new and I have had many many problems with it. I finally have had it and decided to see if the internet reported any similar problems and to my amazement there are many people out there with the same problems, but here is my story. I have had to have the brake lights electrical system on both sides replaced, molding around the license plate frame repaired, oxygen sensor replaced, sway bars replaced, windshield wiper motors replaced, left side passenger window motor broke twice, gas tank replaced because it was leaking gas and now it is back in the shop once again because the engine light came on and I had the onstar system do an engine analysis and they said something is wrong with my power train. I took it to the dealership and they call to tell me the gas tank is leaking gas and needs to be replaced. I told them I just had it done in October 2003. They told me I could not drive my vehicle. I see there was a recall done on some 2002 trailblazers due to a problem like this, but they say my vehicle is not one of them. Why? I am having the same problems with the gas tank. This is the second one. I am lucky I took it in or something may have happened if it is this dangerous. I would appreciate a response back. Thank you, kathy yates.

The brake lights on my 2002 trailbalzer have either burned out or failed to function 3 times in the past 2 years. A serious issue since I was notified by other drivers while driving in heavy traffic. Once the bulbs were replaced at the dealership and the other times at local mechanics while I was traveling. Enough of an issue to make me consider trading vehicles.

I have a 2002 trailblazer with multiple taillight / brake light failures. The dealership has resolved my problem, however I thought this information might be helpful to your open investigation. In November 03 my brake lights failed and my dealership "replaced the bulbs" under my then existing warranty. Again, in January, they failed again and I took the vehicle in to have the "bulbs" replaced. While sitting at the counter, I was speaking to a man behind the parts counter and explaining my problem to him. I hadn't finished explaining when he told me I must have a trailblazer. I told him yes, and asked him why. He reached under the counter and took out a box with no less than 20 taillight "circuit boards" and told me they were all from trailblazers.

Brake lights continuously fail in my 2002 trailblazer. The dealer replaced them a couple of times while I was having other cheap made inferior parts repaired or replaced under warranty or recall. The problem is the contacts in the bulb socket are to far apart and do not make a secure connection with the bulb contacts and also do not have electrical grease in them to protect against moisture.

This problem concerns a repeated lighting systems failure. This incident occurred when I was notified by another motorist that when I had the brakes on while stopped at a stop light that both the left and right tail stop lamps were not lit although the center high mounted stop lamp did light to indicate the brakes were on. I had had to have both of these lamps replaced only about 3 months ago when they both burned out within a short period of time, perhaps simultaneously as they might have last week. After the incident last week I put in new bulbs but, unlike the first incident 3 months ago, the lamps would not light properly when the brake pedal was depressed. I will notify the dealer where I bought the vehicle next week when their service department is open again that this problem with my vehicle needs attention.
