2021 AUDI A4 Recalls

Published by Reclia Safety Desk | June 25, 2026

Recall Summary
The 2021 Audi A4 is subject to four distinct safety recall campaigns conducted by Volkswagen Group of America, Inc. (Audi). These recalls address issues related to rear seat belt retractors, rear axle alignment, rear axle lock nuts, and the rearview camera display. Each recall was initiated after the manufacturer identified non-compliance with Federal Motor Vehicle Safety Standards (FMVSS) or a safety defect that could increase the risk of a crash or injury. The recalls are documented by the National Highway Traffic Safety Administration (NHTSA) under campaign numbers 21V606000, 22V034000, 21V295000, and 22V742000.

Affected Vehicle
The affected vehicle is the 2021 Audi A4 sedan and A4 Allroad. Depending on the specific recall, the vehicle may be included alongside other Audi and Volkswagen models from model years 2019 through 2022. Owners should verify their vehicle’s eligibility by checking the NHTSA recall database or contacting an Audi dealer using the vehicle identification number (VIN).

Recalled Components

1. Rear Seat Belt Retractors (NHTSA 21V606000) – The rear seat belt automatic locking retractors may deactivate prematurely. This prevents a child restraint system from being secured properly, violating FMVSS No. 208 (“Occupant Crash Protection”). An unsecured child seat increases injury risk during a crash.

2. Rear Axle Alignment (NHTSA 22V034000) – After repairs for a prior recall (21V295000), the rear axle alignment may not have been inspected. Misalignment can cause premature or uneven tire wear, increasing the risk of a crash.

3. Rear Axle Lock Nuts (NHTSA 21V295000) – The lock nut on the trailing arm of the rear axle may break due to stress corrosion. A broken lock nut can misalign the rear axle, potentially causing loss of vehicle control and increasing crash risk.

4. Rearview Camera Display (NHTSA 22V742000) – A software issue may cause a blank or black screen instead of the rearview camera image when the vehicle is placed in reverse. This violates FMVSS No. 111 (“Rear Visibility”) and reduces the driver’s rear visibility, raising the risk of a crash.

What Owners Should Do
Owners of a 2021 Audi A4 should take the following steps:

– Check for open recalls – Visit NHTSA.gov/recalls or call the Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). Enter the vehicle’s 17-character VIN to see all unrepaired recalls.

– Contact an authorized Audi dealer – Schedule an appointment to have all open recalls performed. Repairs are free of charge. For recall 21V606000 (seat belts), dealers will inspect and, if necessary, replace the middle-rear seat belt assemblies. For 22V034000 (alignment), dealers will inspect the rear axle, adjust alignment, and replace any unevenly worn tires. For 21V295000 (lock nuts), dealers will replace the lock nuts and associated bolts if needed. For 22V742000 (rearview camera), dealers will update the infotainment unit software.

– Owner notification letters – Audi mailed notification letters for these recalls on the following dates: August 27, 2021 (21V606000), June 4, 2021 (21V295000), March 3, 2022 (22V034000), and October 25, 2022 (22V742000). If you did not receive a letter, your vehicle may still be affected.

– Customer service – Owners can call Audi customer service at 1-800-253-2834. Refer to Audi’s internal recall numbers: 69CS (seat belts), 42L1 (lock nuts), 42L5 (alignment), and 91DZ (rearview camera).

– No immediate parking action required – None of these recalls require the vehicle to be parked immediately or outdoors. The recalls do not involve over-the-air updates; all repairs must be performed at a dealership.

Owners should address all open recalls promptly to ensure the vehicle meets federal safety standards and to reduce the risk of injury or crash.
