2021 Audi e-tron Electrical System Problems

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 condition. I took the vehicle to an authorized Audi dealership. The dealer cleared the fault codes and returned the vehicle to me without replacing any high-voltage battery components or performing repairs. I was not advised that the vehicle was unsafe to drive. A few weeks later, the high-voltage battery warning light returned. I brought the vehicle back to the dealership, where I was informed that a high-voltage battery module had failed. The dealer has now recommended replacing the battery module at an estimated cost of approximately $12,000. I am concerned that the vehicle was returned to me after a reported high-voltage battery fault was simply cleared rather than repaired. I am also concerned that replacing only a single battery module may not address the underlying issue. Additionally, I am aware of high-voltage battery recalls involving other Audi, Porsche, and Volkswagen electric vehicles, and I believe this failure should be evaluated to determine whether it represents a similar safety defect. This issue presents a significant safety concern because it involves the high-voltage battery system, loss of regenerative braking, reduced vehicle range, and a reported battery thermal-related fault. I am requesting that NHTSA investigate whether this is a broader safety issue affecting 2021 Audi e-tron Sportback vehicles.

I own a 2021 Audi e-tron with approximately 58000 miles. Beginning in March 2026, the vehicle developed intermittent Virtual Cockpit/instrument-cluster problems with blank display. I reported the condition to Audi dealer of Princeton NJ. The vehicle subsequently experienced two dead 12-volt battery incidents and became inoperable. The second 12 volt battery was new. Following the most recent incident, the Audi dealer diagnosed the Virtual Cockpit/instrument cluster as causing a drain on the 12-volt battery and recommended replacement at a cost of approximately $3,500. The replacement part is unavailable, and Audi has provided no estimated delivery date. The vehicle has remained out of service since July 03rd 2026. This condition presents a potential safety concern because failure of the instrument cluster may prevent the driver from reliably viewing speed, warning indicators, vehicle status, range, and other safety-related information. The recurring 12-volt battery discharge may also leave the vehicle unexpectedly disabled. The vehicle is additionally showing an indicated range of only approximately 160 miles at 100% charge. Audi has not established whether this is related to the instrument-cluster failure, high-voltage battery condition, battery-management system, software, or another electrical defect. Audi has not provided documentation of a comprehensive high-voltage battery health and capacity evaluation. Audi issued a recall or service campaign affecting other 2021 Audi vehicles for substantially similar Virtual Cockpit/display problems. However, Audi states that my VIN is excluded and has not provided a technical explanation identifying a different component, part number, software version, supplier, or failure mechanism. I request that NHTSA evaluate whether the recurring instrument-cluster failure and 12-volt battery discharge constitute a broader safety defect and whether the existing Audi recall or service-campaign population should include this car.

Audi dealership charged fee for a repair that they the,selves acknowledged is under a technical service bulletin and despite my having extended warranty that is supposed to cover such repairs. This is for the main media interface going blank repeatedly every ~5 minutes or so while driving. Audi charged me for a repair that is a known safetyissue and is covered under warranty.

Tied with NHTSA Recall 25V900 - Review Camera Software. Dealer was unable to complete the recall due to internal malfunction of USB Interface on vehicle. Dealer quoted a non itemized Repair Estimate of $1,045.50 to replace the interface in order to be able to complete the open recall. No visible user caused damage to interface and prior Technical Support Bulletin (2066315) for issues with USB covering specific vehicle. Given the dependence on software within our vehicles, the USB interface used to perform required recall work should be covered when failure is internal to the interface module.

What component or system failed or malfunctioned, and is it available for inspection upon request? - While on highway the vehicle loosed all Power indicating Electrical Malfunction How was your safety or the safety of others put at risk? It happened on I-35 Freeway twice putting me in danger of 18 wheelers around me. I am afraid to be in the vehicle even if they return it to me. Based on records this issue has been present on the car since it rolled off manufacturing. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes and Dealer has reproduced it and has the car with them for 5 Plus months. Have replaced many components and are not able to resolve it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? South Austin Audi Dealer has been working with Audi Corporate Technical team and have replaced 5 parts to no resolution. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Electrical Malfunction - Red light flashing to pull the care over to the emergency lane but there is no acceleration - you are left to depend on whatever momentum is left on the car. Based on records this issue has been present on the car since it rolled off manufacturing. Based on records this issue has been present on the car since it rolled off manufacturing.

The contact owns a 2021 Audi E-Tron. The contact received notification of NHTSA Campaign Number: 23V867000 (Electrical System). The part to do the recall repair was not yet available. The vehicle was taken to the dealer, where it was diagnosed, and determined that the battery module had failed and needed to be replaced. The dealer confirmed that parts were not yet available. 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 issue, and a case was opened. The contact had not experienced a failure.

The vehicle's central locking system does not properly communicate with the keyfob resulting in the doors not unlocking as intended. I have had my child in the car seat in the back and if i accidentantly touch the handle the wrong way the doors will lock and I am unable to use the unlock feature to get my kid out. This could be a serious safety issue if someone becomes trapped in the rear seat and the central locking system does not allow unlocking of the doors.

My Audi E-tron has a consistant problem with the MMI (Multi Media Interface, the main computer for the car). When I am driving, all the screens will go blank, I cannot see my speed, I have no HVAC controls, I am basically driving blind. To fix the issue, I have to pull over, turn off the ignition, open the driver door, close the driver door, put my foot on the brake, start the car again. Sometimes this happens in the first few minutes of driving, othertimes it happens when I am on the highway which poses a huge safety risk. This saftey issue has presented itself at least 5 times in the last 12 months. I have told Audi about this issue several times and they completely deny it exists. This is my 3rd Audi in 15 years and like every other Audi issue I have had, Audi will completely deny there is a problem until there is a recall forced on the company. It happened with the brakes of my last 2017 q7 and Audi kept telling me there was no issue, it finally got settled with a recall on the vehicle. The MMI has been an issue on this car since day 1. The MMI shutting off and putting everyones lives at risk has been going on for the last 12-18 months.

This issue occurred with my Audi a year after purchasing it and the vehicle had 19,282 miles on it at the time. I received an "Electrical System Malfunction - Please contact service" error message (in yellow) on my 2021 Audi etron vehicle display. The message was displayed for a few minutes as I was traveling home from work and then disappeared. The following day, I was on my commute into work on the highway, traveling 70 mph, and received an "Electrical System Malfunction - Safety stop vehicle" error message. The vehicle immediately started displaying other error messages and the motor turned off, while the vehicle was in motion. Luckily, I was able to move to the shoulder of the highway safely. The experience was frightening as I was traveling 70 mph and experienced a complete vehicle shut down with little to no warning. The Audi etron had to be towed to the dealership to be repaired. The dealership had my vehicle for 3.5 weeks while they repaired the car. They inspected the vehicle and determined it was a front motor failure and it had to be replaced. I am extremely concerned about the safety issues the Audi etron has created for me and others, especially given that it is a newer vehicle with low mileage.
