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.

Anytime the wipers are set on intermittent, they completely stop at any given time. You can be driving along and the wipers will just stop with the blades positioned perpendicular to the base of the windshield. The wipers sometimes resume within a few seconds or there is up to a several second delay. I have to move the stalk to low or high to get the wipers to move again. I wouldn't normally complain because of the age of the vehicle, but it was recalled for wiper problems in its infancy due to water getting onto the circuit board. I can only assume the fix did not keep the water out and the circuit board was damaged.

It has the "memory" mirror option which includes featuring memory set options for driver 1 and driver 2, as well as rearview curb assistance (the mirrors will tilt down to your setting to help parallel park when in reverse). This option worked great for a while. Then, in 2003, the mirrors started acting crazy. They would click excessively, tilt towards the sky or down at the ground. The local Chevrolet dealership replaced the actuators (under warranty) to see if it corrected the problem. They worked again for a while. Then, the mirrors quit holding their memory, causing me once again to have to reset the mirrors every time I got in the car. Also, the mirrors appeared to move at some point while I was driving. On numerous occasions, I thought my mirrors were reset, and then I would look to change lanes and find my mirror tilted up towards the sky or some erratic place.

GM ignition switch recall needs to be expanded. My mother purchased a 2002 Chevrolet Trailblazer new. Approximately 5,000 miles into ownership, the car would "drop" various electrical components while driving down the road. For instance, while driving, the engine would continue to run, but the wipers would stop working, HVAC would turn off, air bag and ABS warning lights would illuminate, etc. Dealer had no idea how to fix. Eventually they replaced the ignition switch and the problem was solved. To my knowledge, GM never issued a recall, but I'm sure the issue is not isolated. These switches were unreliable across several vehicle lines, please investigate gmt 360 platform well.

All Trailblazer Tahoe and Envoy have the problem when you disconnect the battery it causes theses actuators to slam open and shut breaking them. The dealership is telling me almost 2000 dollars to fix this safety issue. This is a safety issue because I live in Michigan and depend on the heat to unthaw my windshield. Considering this is a manufactures problem and any mechanic knows to disconnect the battery to work on the vehicle. So what is this crap? do I have to retain a lawyer for this issue if someone could please contact me at [xxx] my name is [xxx] I would like to resolve this issue with a recall. Heat in winter I would say is a safety issue that needs to be recalled. I will be persistent with this.

There was a vehicle recall campaign regarding the wiper motor on my 2002 Chevrolet Trailblazer. Water would work it's way into the wiper motor on certain models and short the motor and circuit board out. General motor's fix was to inspect and reseal the motor. Not long after general motor's supposed fix, the wipers on my Trailblazer would stop in mid wipe and then restart again a few seconds later, which I regard as a serious safety related issue. I took the vehicle back to the dealer and was told the circuit board had shorted out and the wiper motor would need to be replaced at $332.67. This was the same problem the recall was supposed address. In my opinion, general motor's (fix) was a stopgap measure and not a permanent solution to the problem and a ongoing safety related issue. Not to mention the hundreds of dollars that customers have had to shell out for this repair over the years. I feel that the NHTSA should make general motor's recall this vehicle once again for a permanent solution to this problem. I also feel that anyone who has paid for this repair should be reimbursed for their out of pocket expenses.
