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.

About 1 month ago we started smelling gas fumes and than we started to notice gas was leaking from our tank onto the ground. When we brought it into the mechanic they told us we had a leak in the fuel tank. Our car is a 2002 Trailblazer ltz and it just hit 52,000 miles. It has been garage kept the entire time. When we contact the dealer we bought it from they said it was no longer under warrenty and there was not tsb's out. After some research I found the tsb that was put out for this defect. I have not recevied a recall and am experiencing a difficult time getting this problem resloved.

I also had a noise from underneath vehicle getting louder over 3-4 days then smell of gas began and got very strong after a couple days. When it smelled bad we took it to a shop and the fuel sending unit and filter needed replaced. There was a small hole which was caused by corrosion that the mechanic said he had never seen this before. He said if I hadn't brought it when I did that the vehicle could have caught on fire.

: the contact stated while driving various speeds, the odor of fuel was noticed in the cab of the vehicle. It was driven to an independent repair shop, who replaced the synchronize valve, fuel sending unit and fuel filter. The consumer was told the problem was with the sending unit. The consumer had the problem repaired, however it resurfaced again. Updated 12/18/06.

Transmission does not shift smoothly and the vehicles seems to "skip" when driving, had checked and was told the transmission needs servicing. Also, several times the car has jumped from 2wd to 4WD on its own, while being driven. Thankfully only when going approximately 10 - 15 mph. Now the service 4WD light is on. Fuel filter needs replacing. Oxygen sensor needs replacing. This car is a 2002 with 71,000 miles.

Problems with air bag dash light, fast engine idle, air conditioner, rear hatch inner strap broke, etc... the airbag light was intermittent. The sir module was replaced, and there was poor terminal connection at the sir wiring harness, and was traced/repaired on the left side impact connector and the codes were cleared. The engine idled fast(especially at start up, and the fuel mileage was 13 mpg. The results of the evaluation and repairs were: Passenger impact connector was loose(repositioned/connected), idle within specifics, the emblem had fallen off, the rear hatch inner strap had broken, the transmission seemed to take long to shift into gear(happened sometimes when cold), and the PCM needed to be reprogrammed(J6355 power train controller PCM). There was a thumping sound in the rear differential when shifted, the A/C would blow out cold air when the A/C indicator was off, hot air would come out of the defroster area on the dash when the indicator was set for heater on the floor, the engine made a tapping sound, the lift gate weather strip had come apart, and the battery kept losing charge(3 occurrences).
