What Happened
The lock nut on your rear axle is a crucial part that keeps the wheel connected to the suspension. In some 2021 Audi models, this nut can break due to corrosion, which can cause problems with the rear wheel.
Risk if Unfixed
If the lock nut breaks, the rear wheel could become misaligned, making it harder to steer and increasing the risk of a crash. You could lose control of your vehicle, especially when driving at high speeds or on winding roads.
Free Fix
Your Audi dealer will replace the faulty lock nut and associated bolts with new ones, free of charge. This repair is a precautionary measure to ensure your vehicle is safe to drive.
