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.

2012 Chevrolet Impala Owner Comments

problem #1

Jan 032012

Impala 6-cyl

  • 120 miles


Engine makes a ticking noise or knocking noise while accelerating, I'm very concerned with this being that this noise started the next day after I had the car home from the dealership. I'm hoping this isn't a safety concern but it sure is a customer dissatisfaction. The dealer has tried to isolate the noise and could not and said I would have to wait for the manufacturer GM to figure out what is wrong. I'm very depressed about this having spent good money on a new car just to have it make more noise that a 40 year old car, and then being told I have to wait till someone complains enough to see if it can be fixed. I been told that this is a new engine in the Impala and now am wondering if this engine is going to become a problem for thousands of people like myself. I have read some major concerns from people about the 06 Impala and hope this isn't where my car is headed. Any help that I could get would be very appreciated, thank you.
