   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.

   Moisture build-up in the high-voltage electrical system through a faulty seal on the charging socket, which can cause a short circuit and significantly increase the risk of a vehicle fire. If you get a warning light saying "electrical system: fault," you should stop driving immediately, park outdoors away from structures, and not charge the vehicle. Braking problems caused by sub-standard welding within the ABS rotor and shaft. High-voltage battery modules that may overheat, also increasing the risk of fire. An infotainment unit that can become internally damaged when the vehicle is shut off, resulting in an inoperative rearview camera display a federal safety standard violation. This clearly shows the vehicle was badly manufactured, during a chip shortage in 2020. This vehicle is a complete failure by Audi and puts so many innocent peoples lives at risk.

   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.

   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.

   I was driving on the highway and my sunroof spontaneously exploded. Nothing hit it, but there was a loud noise like a gunshot and the roof exploded outwards. Shards of glass landed in front of the car behind me who swerved to avoid them.

   On five separate occasions across two separate drivers, we have experienced a partial brake failure in this vehicle. We strongly believe this to be a software defect and not a mechanical fault. On the e-Tron, the first portion of the brake pedal swing typically activates the regenerative braking. About mid-way through pressing the pedal, it changes to "real" mechanical brakes. When this brake failure occurs, we get to that midway point and the car lets off the regenerative braking but does NOT apply the mechanical brakes, so the end result is that the more you press the brake pedal, the less it works. Three of these five occasions occurred in one day, so by the time the third time came around, I was really paying attention and I'm very confident this wasn't driver error. In at least one case, the only reason that a crash was avoided is because the automatic braking / forward collision system activated. The vehicle has been inspected by a dealer, who found "No Repairs Recommended". We requested an update to the ABS module software, as this software update is known to resolve multiple other problems with the braking system (see TSBs 2072977, 2061906) but we were denied the update.

    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.

    Twice in the span of 3 months my 2021 Audi eTron with less than 25K miles shutdown while driving with an error message "Electrical system: malfunction! Safely stop vehicle." At this point the drive train is completely disengaged and all that can be done is coast to a stop with limited ability to steer or control the vehicle. The vehicle must then be towed to a dealership. If this had happened on a busy multi-lane highway, there is a high probability of an accident occurring putting occupants of the car and other cars at risk. In both cases there was no prior warning of any problem with the vehicle. The first repair in July required Audi to replace the master controller located in the battery pack and replace the front engine due to a fluid leak. This took 6+ weeks to complete. I had the car back 5 weeks after the first repair when it happened again. I am still waiting diagnosis on second repair.
