Owner reports

Selected complaints filed with NHTSA by 2022 Audi e-tron owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2022 Audi E-Tron. The contact received notification of NHTSA Campaign Number: 23V867000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated while charging the vehicle, the contact noticed that the charging outlet was burned and melted, and the juice box, the plug, and the charging cable had melted, nearly causing the contact's residence to catch on fire. The vehicle was taken to the dealer, where the onboard diagnostic software was installed on the vehicle and an unknown kit was replaced as an interim repair. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 13,000. VIN tool confirms parts not available.

CATASTROPHIC ELECTRICAL FAILURE - SMOKE IN CABIN While driving with passengers, dashboard displayed "ELECTRICAL FAILURE - PULL OVER WHEN SAFE" followed by loud explosive POP and cabin filled with SMOKE. ROOT CAUSE: Prior undisclosed collision damage. Dealer (Morrie's Golden Valley Cadillac) removed front bumper in June 2025 (Repair Order #78683), then sold vehicle as "no accidents" in August 2025. Subsequent inspection revealed cut wiring and improper repairs (Invoice #94609). CURRENT STATUS: Vehicle inoperable 3+ months. Audi corporate technicians have repaired major problem however vehicle still has charging issues that happened right before the catastrophic failure unable to repair. SAFETY CONCERN: Smoke-filled cabin endangered occupants. Potential fire hazard.

The contact owns a 2022 Audi E-Tron. The contact stated that while driving at various speeds, the vehicle independently switched to SAFE Mode and failed to properly accelerate while depressing the accelerator pedal. Additionally, the mileage range was reduced, and the battery recharging time increased. The failure started after the vehicle was repaired under the NHTSA Campaign Number: 23V867000 (ELECTRICAL SYSTEM). The vehicle was taken to the local dealer, but no failure was found with the vehicle. The vehicle was later taken to an independent mechanic who reported that the amperage of the battery had been reduced from 400 amps to 130 amps. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 16,000.

The contact owns a 2022 Audi E-Tron. The contact stated while driving at an undisclosed speed, the rotors were pulsating and shaking. The contact stated while driving 65 MPH, unknown sensors engaged without an object or vehicle nearby. The contact had set the system to the lowest sensitivity. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the front rotors were worn. The vehicle was repaired, but the failure recurred. The dealer informed the contact that the vehicle had not been driven properly and was a maintenance issue. The manufacturer was contacted and opened a case. The approximate failure mileage was 15,000.

No incident occurred. However, Audi recalled my EV (2022 Audi E-tron) months ago, stating there exists a fire hazard associated with these vehicles. Audi has not provided any effective remedy. The sole advice offered was to refrain from charging the battery beyond 80%. However, Audi has not substantiated the claim that this measure is protective, and it also restricts the performance and intended range of the affected vehicles. I contacted Audi of America and my local Audi dealer, but both entities have been unhelpful and unable to offer any reassurance or scientific data. Battery monitoring software is allegedly scheduled to be released this quarter (originally promised in the final quarter of 2024). This proposed solution appears insufficient. Thermal runaway could potentially lead to a fire without sufficient warning to protect consumers, even with software in place. …

Purchased a used 2022 Audi E-Tron GT with an open NHTSA safety recall for high-voltage battery fire risk (Recall 24V726 / Audi 931A). The recall remedy had not been performed at time of purchase. The selling dealer completed a pre-delivery inspection two weeks prior to sale with full knowledge of the open recall. Within 7 weeks of purchase, the vehicle entered limited performance mode (turtle mode) while driving and had to be towed. A high-voltage coolant pump was diagnosed faulty and replaced. Days later, the vehicle powered down completely while driving. Fault codes indicated an implausible signal from the HV battery controller. The battery management controller (J840) was replaced. After replacement, additional faults were found. The HV battery switch box (SX6) was also diagnosed faulty and replaced. The vehicle was out of service approximately 18 days for this event alone. …

The vehicle is experiencing an intermittent but active 'Electrical system: malfunction!' safety alert on the dashboard and myAudi app, caused by an internal high-voltage battery cell circuit fault (Diagnostic Trouble Code P0DB400 / U04A300) and a failure in the battery thermal runaway detection system. When the fault occurs, the vehicle suffers a complete loss of regenerative braking, severely affecting stopping predictability and vehicle handling. An authorized Audi dealership (Audi West Chester) confirmed the internal module failure under TAC Case NF-1675032 and directed a full battery module replacement. Diagnostic scans have confirmed two highly critical manufacturer trouble codes: P0DB400 (Hybrid/EV Battery Cell Balancing Circuit "C") and U04A300 (Invalid Data Received From Hybrid/EV Battery Interface Control Module "C"). …

While driving, the vehicle displayed three simultaneous warnings - "Drive system malfunction, safely stop vehicle," "Electrical system malfunction, restart not possible, contact service," and "All-wheel drive malfunction, limited stability" - and lost propulsion completely. This occurred on at least two separate occasions while driving. After each event, the vehicle would not restart for approximately 15 minutes, after which it began working again temporarily. The vehicle was taken to an authorized Audi dealer, which found no coolant in the front drive motor and diagnosed a fault in the SX6 high-voltage battery switching module, which controls connection of the high-voltage battery. The SX6 module was replaced. …

First time in November the sign came on that there was an electrical system failure. We took the car to the shop, in Audi Raleigh and they said that they fixed the issue. Although, we had to wait for an available appointment for over a month. This time, after 3 months, the same sign came on, electrical system failure, plus all wheel drive faiture. While driving to the dealership the car stopped abbraptlly on the highway and we had to call a tow truck. This was scary because the car stopped and just would not move,. Audi knows that all 2022 -tron models have this issue and disregards the safety of the customers.

I was driving on the interstate freeway in normal conditions when my 2022 Audi E-tron suddenly showed a message "Electrical system malfunction!" and lost all power to the motors. Thankfully I was in the rightmost lane already and I was able to steer and coast over to the shoulder even while pressing the gas pedal had no effect. If I had been in another lane it could have led to a major accident if my car stalled in the middle of a busy freeway. I had the vehicle towed to the local Audi dealer service center, but so far they have not been able to diagnose the problem.
