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.

2011 Chevrolet Impala Owner Comments

problem #1

May 062013


  • 42,000 miles


When my Impala was 4 years old and 42000 miles(April or may of 2013), both rear door locks refused to lock or unlock. I contacted my dealer and he stated that it was out of warranty. I then contacted gms customer service which reiterated the same thing. After investigating online, there are quite a few blogs with customers who have the same problem. To replace these locks costs approximately $800. I contacted your organization this morning and they told me to contact Chevrolet at 1-800-222-1020. When I contacted them, I was informed that the serial number did not fall under any recalls. However, Chevrolet does have a door lock recall.
