“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. …”
NHTSA complaint #11569181, filed 2024-02“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? …”
NHTSA complaint #11731663, filed 2026-04“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. …”
NHTSA complaint #11489296, filed 2022-10“E-Tron with 9300 miles, received Electrical Malfunction: Contact Service. Audi service said to bring vehicle in. On way to dealer, warning changed to Electrical Malfunction: Pull over safely and then, before being able to do so, the vehicle jerked and died while in traffic. Fortunately, I had decided not to take the freeway and had enough momentum to coast to the side of the road, but the experience certainly stressed my nerves, especially since I could have chosen to be on the freeway in heavy, fast, multilane traffic. …”
NHTSA complaint #11466552, filed 2022-05“While I was on vacation a couple states away, I drove the Audi Etron Sportback for the first time since three days before when I drove to the vacation destination. After several minutes driving I got an ELECTRICAL SYSTEM MALFUNCTION - PLEASE CONTACT SERVICE notification. Several minutes later I got very large red alert that said ELECTRICAL SYSTEM MALFUNCTION - STOP VEHICLE . I immediately pulled over to the side of the road into a parking lot just before the electric motors shut down completely. This put myself and my dog in danger. …”
