## What is wrong

Issue:

On certain vehicles, the lock nuts for the rear trailing arm bolts may be defective. If a nut breaks, there could be sudden changes in rear wheel alignment. This can cause a loss of vehicle stability.

Safety Risk:

Reduced vehicle stability could cause a loss of control and increase the risk of a crash.

Corrective Actions:

Audi will notify owners by mail and instruct you to take your vehicle to a dealer to replace the rear trailing arm lock nuts. If necessary, the associated bolt\(s\) will be replaced as well.
