What Happened
The lock nut is a critical part that keeps the rear axle of your vehicle stable. In some 2021 Audi models and certain 2019-2021 models, this lock nut can break due to rust and corrosion.
Risk if Unfixed
If the lock nut fails, the rear axle can become misaligned, causing your vehicle to pull to one side while driving. This can make it difficult to control your vehicle, increasing the risk of a crash.
Free Fix
Your Audi dealer will replace the faulty lock nut and any associated bolts with new ones, at no cost to you. You should schedule the repair as soon as you receive the recall notice, and it's free of charge.
