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

Major electrical problems inside the vehicle. I have owned it less than a year.the vehicle has been in the shop twice in the past two weeks. Exiting the freeway the I had a complete power failure. The vehicle completely stopped and locked up and there was a semi truck behind me! my vehicle was moving and in "drive" when this happened. I had two of my toddlers in the car with me! the vehicle was taken into a local dealer and unfortunately they could not find anything wrong with it. Apparently, when the vehicle is restarted it erases the codes in the engine as to what caused the problem. Well, it happened to me again this evening. Same problem. This will be my 5th time of bringing this vehicle in for electrical problems in less than a year. I only have 9400 miles on the vehicle and bought it brand new. I do not feel safe driving this vehicle with my 5 children as passengers. Is there a way GM can get me a better running vehicle? I paid a lot for this vehicle and am very unsatisfied with it's performace. There always seems to be something wrong with it. The connell Chevrolet service here in killeen has been very helpful. I feel sorry for them because they did not sell me this vehicle but they are the ones nice enough to try and fix the multiple problems.

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.
