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.

What this page does not include

NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
