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.

53000 miles. When car is in motion. Car goes to low power more and check stabili-track message comes on. Car shakes bad at idle, idles too high, (almost to a point where brakes won't hold at a stop). Sh*t down and restart car goes back to normal conditions for short puerile of time. Check engine light comes on and code for throttle body malfunction is detected. Called Buick service number and was told it would be under warranty. Made appointment with dealership checked code and determined same code issue and it was not covered under warranty. Did. Not have them fix it yet. Cost is excessive and was told under warranty by manufacturer. Waiting on customer service call back. Car is unsafe to drive. Have seen many similar complaints but have seen nothing done by Buick or ntsb.

The vehicle lost most of its power, the engine light came on and it would not even accelerate to 40 mph. This is a very dangerous situation on the highway where the minimum speed is 45 mph. Apparently, this is not uncommon with that engine. I am now paying $611 to replace the throttle body that apparently is the source of the problem on this essentially new car.

Timing chain and water pump chain and all the other good things that go along with this needed to be replace on my 2011 Buick Regal 2.4L engine just under 25000 milesthis should not have happened at this mileage. What if this decided to go while I was on the highway..this seems like a problem that needs to be investigated.
