Volkswagen Group of America, Inc. (Audi) is recalling certain 2019-2023 Audi E-Tron Quattro, 2020-2023 Audi E-Tron Sportback, 2024 Q8 E-Tron, Q8 Sportback E-Tron, SQ8 E-Tron, and SQ8 Sportback E-Tron vehicles. The fastener that connects the brake pedal and the brake booster may have been improperly assembled during manufacturing, which can cause the brake pedal to detach from the brake booster.
Consequence: Brake pedal detachment can cause a loss of brake function and increase the risk of a crash.
Remedy: Dealers will inspect and tighten the pushrod screw joint as necessary, free of charge. Owner notification letters were mailed on April 28, 2026. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 46P7. This recall expands previous NHTSA recall number 24V621. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on April 17, 2026.

The component that failed is battery cell 6 within the internal high-voltage traction battery pack assembly. The vehicle is currently experiencing a severe high-voltage isolation/safety breakdown, flagging diagnostic trouble code B1D9EF1 while running on manufacturer software version 0490. The vehicle and its high-voltage battery pack are currently located at an authorized dealership and remain fully available for inspection upon request. The failure of an internal high-voltage battery cell creates an imminent risk of a sudden, uncommanded hig…

Multiple times and at random times the vehicle reports "Central locking: malfunction! See owner's manual". When this happens, the driver's door is completely locked and driver cannot exit the vehicle. Door cannot be opened from outside either. So far this has only caused real delays, but this is a safety issue. I have reported the problem to Audi dealer but they advised that Audi has instructed them to apply software updates and not replace any parts.
