Component
SUSPENSION:REAR:AXLE:NON-POWERED AXLE ASSEMBLY
Manufacturer
Volkswagen Group of America, Inc.
What Happened
The lock nut on your vehicle's rear axle helps keep the suspension in place. In some 2021 Audi models, this nut can break due to corrosion, causing damage to the axle.
Risk if Unfixed
If the lock nut breaks, the rear axle can shift out of place, making it harder to steer and control your vehicle. This could lead to a loss of control and potentially increase the risk of a crash.
Free Fix
Your Audi dealer will replace the faulty lock nut and any damaged bolts, free of charge. You should schedule the repair as soon as you receive the recall notice.
