What Happened
The part that connects your rear wheels to the rest of your vehicle is the non-powered axle assembly. In some 2021 Audi models, a small lock nut on this assembly can break due to corrosion.
Risk if Unfixed
If the lock nut breaks, it can cause the rear axle to misalign, which could make your vehicle unpredictable to steer and increase the risk of a crash.
Free Fix
Your Audi dealer will replace the lock nut and any affected bolts for free. You should schedule the repair as soon as you get the recall notice, and it won't cost you anything.
