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.

  • 12,000 miles
For about 6 months I have been having problems with stalling after slowing and then accelerating. The first 3 times were not as frightening as the one that occurred on 7-7-2014.returning from a trip to new orleans, as I exited the interstate and began to ramp off, the car stalled to the point of no control of the steering. It lurched to regain speed and finally recovered. We took it to the dealer on 7-10-2014 and they did diagnostic check and found no obvious problem which is difficult to do when the problem is intermittent. I am afraid of driving the vehicle until it is repaired. The dealer said to bring it back if the problem occurs again. My question--what if the next time it causes a crash? can you please help me get resolution as my warranty expires in Feb. 2015.

The contact owns 2012 Buick Lacrosse. The contact was driving 25 mph when the vehicle suddenly stalled without warning. The contact shifted into neutral and was able to restart the vehicle. The failure recurred three times. The vehicle was taken back to the dealer who attempted to inspect the failure for over ten days, as well as perform several test drives but was unable to duplicate the failure. The manufacturer was notified who advised the contact that they would send a representative to further inspect the failure. The vehicle was not repaired. The failure mileage was 1,300 the consumer sold the vehicle back to the dealer, because they were unable to determine the problem. Updated 06/01/12
