What Happened
The lock nut on your rear axle is a critical part that keeps the suspension stable. In some 2021 models, this nut can weaken and break due to corrosion, which can cause big problems on the road.
Risk if Unfixed
If the lock nut breaks, the rear axle can become misaligned, making it harder to steer 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 faulty lock nut and associated bolts with new ones, at no cost to you. They'll also let you know if any additional work is needed during the repair. You should schedule the repair as soon as you receive the recall notice.
