Service Brakes, Hydraulic · Volkswagen Group of America, Inc.
Details
What's wrong: 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 fix: Dealers will replace the brake booster, free of charge. Owner notification letters were mailed September 30, 2021.
