What Happened
The lock nut on your vehicle's rear axle is a crucial part that keeps the suspension components in place. In some 2021 Audi models and certain 2019-2021 models, this nut can crack due to corrosion.
Risk if Unfixed
If the lock nut breaks, the rear axle could misalign, making it harder to control your vehicle. This could lead to a loss of control and increase the risk of a crash.
Free Fix
Your Audi dealer will replace the lock nut and any damaged bolts for free. You should schedule the repair as after confirming availability with your dealer as possible after receiving the recall notice. This timing describes the original 2021 filing; contact your dealer now to confirm the free repair is available.
