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 owns a 2011 Chevrolet Impala. The contact stated that there was a knocking noise heard from under the hood. The contact took the vehicle to the dealer where it was determined that the air conditioning orator had failed. The VIN was not available. The failure and current mileages were 50,000.

Driver side window switch would not operate ( intermittent) at times. The switch was replaced by the dealership (young Chevrolet). During the past month (6/13) the same type of condition has occurred. This problem sounds much like what is happening with NHTSA id - 13V248.

Impala 6-cyl

  • 80,000 miles
I own a 2011 Chevy Impala and for the past couple months on 6 different occasions as I am driving down the freeway my engine power is reduced and "service stabilitrak" light appears. As I have researched and have found that this is a common and very unsafe problem among GM vehicles. I have also found that there is no clear solution to why this is happening with many mechanics stumped and replacing parts in which the problem recurs only a short time later. I have also found replacing what the diagnosis of code P2135 says the problem still may not be solved. As one can imagine that driving down the freeway with a semi, heavy traffic, etc. And losing engine power may lead to significant negative results. I have not installed any parts other than tires after purchasing of vehicle.
