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: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

The vehicle has stalled out 3 times in the past month. Check engine light came on and then reduced engine power light. We could only go 10 mph. Thankfully we were in a residential area and not on the freeway. Dealership said it was a faulty accelerator position module and the PCM needed to be reprogrammed. Lucky us we are over in miles and this is not covered by the warranty.

The caller said that when she would be at a light the vehicle would stall. She would hit the gas pedal and the vehicle would hesitate before taking off. Engine service light came on/off. On July 25, 2005 dealer checked and reprogrammed automatic transmission control module( PCM). On July 29, 2005 dealer checked and replaced the PCM again, and on August 1, 2005 dealer replaced a 02 sensor. Dealer said they could keep and drive vehicle to see if that fixed the problem. Dealer would not give her a temporary vehicle to drive while she waited for her vehicle to be worked on. Dealer said the 02 sensor was the problem. Would not offer an extended warranty. Dealer will not give her enough money for it as a trade in.

On 4 separate occasions vehicle stalled. When this occurred consumer tried to restart vehicle, but it wouldn't restart. Also, keys were stuck in the ignition. As a result, battery was drained. Dealership has replaced automatic transmission shift lock control, battery fuses, programmed the calibration for the engine control module, the starter, and its relay switch.
