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.

#1. on 2 occasions last week, my Trailblazer suddenly lost most of its power, and the engine light reduced engine power came on! I pulled over, cut the car off, then restarted it, and was able to drive home. #2. the seat belts on the front passenger and rear right sides lock up tightly the moment you buckle up. It locks up so tightly that you cannot move if you wanted. These problems showed while driving on miami streets. #3. on 2 or 3 occasions a strong smell of gasoline came into the car while driving. The smell seemed to be coming from inside the back of the car, but I was unable to locate any gasoline back there. On another occasion, I smelled gas outside in the area of gas tank.

Oil pressure gauge drops to 0 when motor is idled up oil pressure returns to normal. This has been an intermittent problem and does not occur all the time. It has happened over the last 2 to 3 weeks and only when I come to a stop. Truck idles fine and shows no other problems
