Electrical System, Unknown Or OtherNHTSA complaint 11765027 · Sep 17, 2026
2021 Audi e-tron, 44,749 miles. Right after a scheduled service at Audi [XXX] on XXX, I noticed a loud droning/humming noise from the drivetrain while driving. The noise tracks with vehicle speed - it gets louder and higher-pitched as the car goes faster. I called the dealership to report it as soon as I got the car back in late XXX. Nobody responded. The noise is still present today, roughly five months later, at about 48,000 miles. The symptom matches Audi's own technical service bulletin 2047920 (rev 7), which covers 2020-2025 Audi vehicles including the e-tron: a humming/booming noise…

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…

Electrical System, EngineNHTSA complaint 11731663 · Apr 16, 2026
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…

Electrical System, StructureNHTSA complaint 11606580 · Aug 5, 2024
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…
Electrical System, EngineNHTSA complaint 11569181 · Feb 1, 2024
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…

Forward Collision AvoidanceNHTSA complaint 11541700 · Aug 30, 2023
While on the highway, the car threw the following error message: "Electrical system: malfunction! Safely stop vehicle" I was able to drive for a mile or so to pull into a residential street and at that point, the vehicle just wouldn't move. It was essentially stalled, and I had to call roadside assistance to have it towed. After a few days, I receive an update from the dealer that the motor needs to be replaced - this car has done like 19,000 miles and the motor has apparently died abruptly. On further research, I noticed that there have been other etron owners that have had to deal with…
