2021 Audi E-Tron Powertrain (other) Problems

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.

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.

Repeated sudden loss of forward propulsion power associated with multiple warning messages about drive system and electrical system malfunction. Because the problem is sudden and the car has no forward propulsion power the car is left blocking traffic with occupants still inside. This has occurred multiple times over the last 6 months and no cause has been identified yet.

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 similar issues, often happening abruptly and while their car was in use. I'm glad that I was able to pull over to safety and there was no other serious injury - this could have ended very differently.

My vehicle has 13,090 miles on it. I have had two electrical issues that affected the A/C button not working on the panel display, which were both fixed by the dealership. Last week, after dropping my children off at school, a warning sign came on my display that said "Electrical system malfunction - Safely Stop the Vehicle." I wasn't in a spot to stop the vehicle safely so I started to drive to a parking lot where I could. While trying to take off at an intersection after the red light turned green, the car completely stopped with the nose of my car sticking out into the crosswalk/intersection. The accelerator would not respond and I could not move. I had to ask some people standing by to help me push my car off into a parking lot where I had the vehicle towed to the dealership. After being at the dealership for 6 days, they let me know that it has been verified that a motor is going to need to be replaced and they put an order in for it. They said they aren't sure on when the vehicle will be ready for me to pick it up.

Had multiple instances as I approached intersection stops of the vehicle suddenly jerking and the drive train becoming disengaged. The car maintained electrical power and had working steering and braking as I coasted to a stop. This occurred 5 times over the course of 3 miles as I attempted to make my way home, and I would estimate that each occurrence happened at a speed under 10 mph. The car was near full battery charge level when this occurred. With each occurrence, the vehicle would generate a series of warning messages (indicating failures of one system after another, ranging from electrical system, to drive train, to collision avoidance, to tire pressure monitor, etc.) and would indicate the car was disabled, should be pulled over safely, and that I should call the dealer for support. For about 30 seconds, the car could not be put back into "drive" mode, but after that time I could restart the car and was able to resume driving. Fortunately, this all occurred when I was driving on neighborhood streets during a non-busy period, and I was able to carefully make my way back home. But having a car suddenly and randomly disabled while in motion could obviously be a significant safety issue. The following day I had the car towed to my local Audi dealer and at this point have received no indication of what the problem might be or even when it might be assigned to a technician for diagnosis. In looking online at Audi owner forums, it's clear that others have experienced the same problem I experienced, along with an array of other significant electrical failures. I've spoken to the Audi Customer Experience support desk and they say the problem I experienced is not one they've been made aware of.

Vehicle traveling when electrical systems malfunction message came on. Said pull over safely and call for service. After car was slowed to a stop, the vehicle was disabled with no forward or reverse drive possible. The car was stranded close to the middle right of the street. Car had to be towed to the nearest dealership around midnight. Problem has been confirmed with the dealer and they are still looking into the problem. Prior warnings messages of headlamp malfunction, Audi emergency assist unavailable, high beam headlight faulty were present about a month prior but did not disable the vehicle.

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. Car was towed to local Audi Dealership and they informed me that coolant had infiltrated the front motor and needed to be replaced. Then other hoses and parts had to be replaced. I am at 4 weeks without my vehicle. The car had 9800 miles on it and was roughly 9.5 months old. Upon searching the internet, there's MANY complaints of coolant infiltrating the motors after a long road trip or after many miles. This kills the motor and some owners report horror stories of having no electrical power in the middle of traffic and in the middle of streets. This is apparent that it is a not a stray issue - but it is a routine issue with the Audi Etron Sportback. And with two motors, and each one costing about $15,000 each - it is likely a very serious and expensive problem that Audi doesn't want to be known. Loss of drive ability (along with other systems) in an EV in traffic or highways is an extremely dangerous and terrible activity, especially for first responders and hazard workers that assist an owner in a vehicle that is very difficult to move when in this state.
