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.

2013 Audi S4 Owner Comments

This vehicle is known for having a faulty mechatronics unit. The mechatronics unit does not work correctly, and causes jerking and instability to the dsg transmission. I have almost rear ended other vehicles at red lights because the transmission will jerk forward unexpectedly and lunge me forward toward the vehicle ahead. This is not only an issue that a prestigious name like Audi should not have, but it is a huge safety issue. Audi of America is aware of this problem, but chooses to ignore it for the sake of not having to cover repairs for all the vehicles reporting this issue. A simple google search will yield results of just how common and widespread this issue is.
