What Happened
The lock nut on your vehicle's rear axle is a small part that keeps the axle in place. In certain Audi models, this nut may break due to corrosion, which can cause problems down the line.
Risk if Unfixed
If the lock nut breaks, it can cause the rear axle to shift out of place. This can lead to a loss of control, making it harder to steer your vehicle and increasing the risk of a collision.
Free Fix
Audi will replace the faulty lock nut and any affected bolts at no cost to you. You should schedule the repair as soon as you receive the recall notice, and it will be done free of charge.
