While driving my 2021 Audi e-tron Sportback Prestige, the high-voltage battery warning light illuminated on the dashboard. At the same time, regenerative braking stopped functioning, resulting in reduced energy recovery and a noticeable decrease in driving range. Before taking the vehicle to an Audi dealership, I had the diagnostic trouble codes read by an independent repair shop. The technician advised me to take the vehicle to Audi because the diagnostic information reportedly indicated a potential high-voltage battery thermal runaway condit…

Recall history

2 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

25V900000 · Back Over Prevention: Sensing System: Camera

Reported: 2025-12-19 (December 19, 2025)

Volkswagen Group of America, Inc. (Audi) is recalling certain 2019-2026 vehicles. Please see the recall report for a complete list of models. A software error may prevent the rearview camera image from displaying as intended. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

Consequence: A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.

Remedy: Dealers will update the software, free of charge. Owner notification letters were mailed January 14, 2026. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 90TV. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on December 23, 2025.

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.
