What Happened
The lock nuts on your vehicle's rear axle are like the nuts that hold the wheels in place. In certain Audi models, these nuts can break due to corrosion, which could cause the wheels to become misaligned.
Risk if Unfixed
If the lock nut breaks, it could cause your rear wheels to shift out of place while driving. This could make it difficult to control your vehicle, increasing the risk of a crash.
Free Fix
Your Audi dealer will replace the lock nuts and any affected bolts with new ones, at no cost to you. This repair is part of the recall, and you should schedule it as soon as you get the recall notice.
