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.

When decelerating at a red light which turned green, attempted to accelerate with no throttle response, even when pushed to the floor for approximately 2 seconds or more (several similar incidents). Second incident, car stalled at a slow speed. Third incident, after accelerating the engine rpms stay reving high after taking foot off the gas for several seconds, and this has happened on several occasions and as recently as 9-16-15. These incidents all occured before and after a complete GM dealer reprogrammed the computer.

This vehicle has a push button engine shut off button. I went to a shopping mall and forgot to shut off the engine. When I returned approx. 1 hour later, the engine was still running. I am concerned should this happen when I park the auto in my closed garage which is located directly below a bedroom. The engine will be running all night and the bedroom will be filled with carbon monoxide resulting in death to the occupants. The vehicle needs a time delay shut off should the driver forget to shut off the engine. The time delay could be set by the manufacturer and should be approximately 15 to 20 minutes otherwise the engine will run forever.

Impala 4-cyl

As a rental vehicle to use while warranty repairs where being performed on my traverse; I had been rented a 2014 Impala. To my surprise the following morning I came to a stop and the engine quite, there was a clear lane within site that I figured I could push the dead vehicle to. I opened the door, while keeping my foot on the brake and positioned myself in the door frame to push. Then I removed my foot off the brake to reach in and place it into neutral and start pushing. To my surprise the vehicle started by its self and accelerated away from me, the door frame almost knocking me down, yet luckily I was able to catch the car and get back to the brake before the car crashed. I came to find out that this was an economic feature on that vehicle. I feel great concern that this car started when my seat belt had been removed and door opened, would they have at least considered some sort of precaution from this occurring. Please take this serious, I know that I was not advised of this feature, and had I not caught the car or gotten knocked down and run over, the outcome would have been much more serious.

Impala 6-cyl

  • 2,770 miles
At 70 mph vehicle slowed on its own. Vehicle information center read "stabilitrak and engine power is reduced". got yellow traction control system light on the instrument panel with a "malfunction indicator light" below the speedometer.engine running rough at ashland, va exit.engine was shut down then restarted with same warnings as before.approximately 45 mins later restarted to have a local Chevrolet dealer look at the car. On restart, all warnings and indicator lights except for the "malfunction indicator light" were out and engine ran guessed that it was probably a "glitch" and it was probably ok to drive.the 800 or so miles to sarasota were without problems. On 8/5/2013 took car to local dealer approximately 3 miles from my home. On entering the dealer's parking lot at approximately 10 mph the problem reappeared I.e. "engine power reduced with stabilitrak" with warning lights as before. This is a safety issue as it can happen at any time!!
