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.

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.

SERVICE BRAKES — Filed 01/11/2025

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.
