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.

The contact stated the check engine light came and the engine started missing. The air reflector on the bottom of the throttle bottle plate disintegrated; the air reflector has gone through the motor. The plate was embedded in the pistons, broke two spark plugs, and bent push rods. He changed the spark plugs. He then pulled the vehicle in and realized the push rods and lifters were bad. He contacted the dealer they offered no free remedy.

The vehicle experienced sudden acceleration going up to a speed of 80 mph. This was an ongoing problem because each time the vehicle was fixed the problem would occur again. (re: ODI#10013779)

On three different occasions my 2001 Chevrolet Blazer has nearly caused me to have a terrible accident. Twice while just driving along at a normal rate, the motor sped up to probably 70 or 80 mph creating a very dangerous situation. It was very lucky that there was nothing in front of me. This has been an ongoing defect with this vehicle. The service manager states that this a very dangerous defect in my car. I am afraid to drive it as each time they say it is repaired, it has happened once again. This is a very serious situation which could easily lead to a dreadful accident and loss of life. It is my opinion that General Motors should offer me a new vehicle in place of the very dangerous one I now own. I could not, in good faith, consider selling it knowing how dangerous it is. Fortunately there has not been an accident with it, but I feel that it could easily happen. On all three occasions, my dealer, buzz chew, southampton, NY has been apprised of this defect and attempted to fix it, but it is only a temporary fix. It is also a know fact that other vehicles of the same make have had the same ongoing defect.

problem #1

Mar 242001

Blazer 4WD

  • Manual transmission
  • miles
Whenever foot was removed from accelerator pedal vehicle failed to slow down without depressing on brakes. Vehicle had manual 4WD. Sometimes would increase due to gravity. Had taken to dealership 4 times for this problem, but it was not resolved. Consumer states when you take your foot off the gas, sensors detect error signals, that cause the systme to inject more gas and air so the vehicle does not slow down.
