Elevated severity
This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.
What the defect is
Volkswagen Group of America, Inc. (Audi) is recalling certain 2021 Audi E-Tron Quattro and E-Tron Sportback Quattro vehicles. Corrosion in the brake booster may cause the Anti-Lock Brake System (ABS), Electronic Stability Control (ESC), speedometer display, and brake assist to stop functioning.
Why it matters
A loss of braking assist, ABS, and ESC will increase the effort and distance required to stop, increasing the risk of a crash.
The remedy
Dealers will replace the brake booster, free of charge. Owner notification letters were mailed September 30, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 47R7.
