What Happened
The lock nut on your vehicle's rear axle helps keep the wheels aligned. In certain 2021 models, this nut can break due to corrosion, causing the wheels to misalign.
Risk if Unfixed
If the lock nut fails, your rear wheels could become misaligned, making it harder to steer and control your vehicle. This could increase the risk of a crash, especially on the highway.
Free Fix
Your Audi dealer will replace the faulty lock nut and any associated bolts with new ones, free of charge. You should schedule this repair as soon as you receive the recall notice.
