On my way to work, my car alerted me to an electrical malfunction and told me to call for service. When I called my Audi dealership, they told me to bring it in for service the following week. After asking if the car was safe to drive, they told me they wouldn't know unless they looked at the car. After pleading with them, they agreed to an appointment that day. On my way to the dealership - about 10 minutes into the trip on a highway, driving at highway speed, all electrical systems in the car started shutting down, and quickly - air conditioning, all safety features like lane keep assist, collision avoidance, etc. The steering became very heavy, the brakes were underperforming. After slowing down safely, the car shut down and was completely immobile and inoperable.

Starter warning followed by electrical system malfunction, these were followed by Multiple warning lights (Lane departure, adaptive cruise control, collision avoidance, etc) then 1 minute later transmission failure and engine failure imminent.... pull over immediately and contact dealer. I turned into a road off main highway within a minute of the last two warnings and as I turned, my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop.

Massive safety liability here. My 2019 Audi A6 was on the highway traveling at 75mph on 4/25/2023 at noon when with no prior warning, all of the electrical systems started failing rapidly. In the course of 90 seconds, there was an electrical malfunction warning, quickly followed by malfunction warnings for steering, brakes, and cascading shutdowns of all systems like the transmission, ABS, Collision Warning, Lane Departure, lights, hazard warning lights, instrument screens/clusters, HVAC, windows- literally everything. A complete failure of every component and safety system while driving highspeed is extremely dangerous. Had this happened at night, I would have been bricked in the middle of the road without headlights, hazard lights, airbags, etc. The car had to be towed away to the dealership and is available for inspection. The dealer is aware of this issue and called it a 48 volt starter/ alternator issue which is apparently systemic/ widespread with 2019-21 Audi 48 volt architectures; parts are generally backordered for months. Please take note: There is an extremely high risk that someone will be killed and seriously injured as a result of this defect. The vehicle is awaiting inspection and repair at an Audi dealership. It is under extended manufacturers warranty at 50,700 miles. No other diagnostics/ inspections/ or reports have taken place yet.

I suffered a complete failure of the vehicle's electrical system. First, I received a warning that the electrical system malfunctioned. This warning went away after two power cycles. Two days later the warning came back and a warning that the battery level was low. I was driving the vehicle approximately 1 mile on the highway when the warning became progressively dire. First the Adaptive cruise control systems became failing one by one, adaptive lane keep, lane departure etc. Then I got yellow warnings about failures in the transmission and the engine. Finally those errors became dire that I must stop the vehicle. I next lost all electrical screens within 2-3 minutes of the cascading dire warnings just as I was pulling off the highway onto side streets. Within 30 seconds I lost power steering and most braking force. I was able to pull over into a bus stop, but with difficulty. I lost all hazard lights, all vehicle lights. I lost the ability to unlock the doors temporarily but this recovered. I could not turn the car back on, I could just hear the started struggling to turn over. None of the screens in the vehicle worked. No lights or horn worked. Thankfully this happened in the late afternoon while the sun was still out. The extreme danger posed by not having emergency lights, power steering and minimal braking capability made this an extremely scary situation. I was advised by Audi Queens that this was confirmed alternator/generator failure.

On December 16, 2022, the alternator on the vehicle failed, which prevented the battery from charging. Luckily, I had just parked the car when all the electronics shut off - otherwise I would have been driving on a busy street with the potential for an accident. The vehicle was towed that day to White Allen European Auto Group in Dayton and is still there and available for inspection. Today is Feb. 6, 2023, and they are still unable to get the required alternator parts and we don't have an ETA. To my knowledge the vehicle has only been assessed by their technician, not anyone else. There were electrical issues prior to the failure. I took the vehicle to White Allen on Nov. 22 due to warning lights for Lane Departure Warning and Lane Keeping Assist turning on and off, as well as issues with the engine shutting off at traffic lights and being unable to get the car to move without turning it completely off and back on again. When I took it to the dealership, they performed many vehicle recalls and repairs including multiple software updates, reworking the transmission wiring harness, servicing the start/stop system, airbag inspection, battery load, control module update, MMI software update, etc. I picked up the vehicle on November 30, 2022. On December 5, 2022, I had to take it back to White Allen because the bottom display screen was not functioning properly. (When starting the car, the top half of that screen was scrambled and the bottom half was dark. After driving for a while, the screen would begin functioning properly). They diagnosed it as a hardware issue with the top screen that controls the lower screen. I was told they would replace the top screen, and the parts should be available by December 29. I asked if the car is safe to drive, and they said I could continue driving it as the lower screen doesn't control anything that might be a safety issue. On December 16, the car stopped working and I had it towed back to the dealership.

They have seen several in this year for A6 and A7's with mild hybrid engines. I'm lucky to be in low volume traffic as there was no power to indicate to drivers around me that my engine quit and not even turn signals worked.

August 25, 2020 traveling wb on I-90 [mass turnpike] passing and 18 wheel tractor trailer with an unmarked white box trailer. Truck 'weaved' to the left into my driving lane as I was overtaking it. I swerved to the left to avoid contact of my 2019 audi a6 premium plus at about the a pillar and the rear wheel area of the box trailer. In my evasive action the car's lane keeping assistant activated as I was about to cross the lines on my left side to avoid the truck, the car took control of the steering and aggressively steering the car back at the tractor trailer. I braked the car as hard I could to avoid collision with the box trailer. None of the collision warning system activated and the car's sensors and cameras did not recognize that I was trying to avoid a high speed collision with the tractor trailer. I brought the car to the dealership [audi albany, latham ny] after return from my trip to have safety systems checked. No fault codes were detected.

Car has a lane keeping assistant which is aggressive. Car doesn't allow you to pass parked vehicle such as a ups delivery truck, pedestrians or bicyclists without trying to steer you back toward the object, vehicle or bicyclist you're trying to pass by pulling to the left toward center roadway lines. Almost struck a ups truck after car abruptly steered car back toward the stopped truck, also occured twice while passing bicyclists and once with a pedestrian. I also had trouble merging onto an interstate highway at high speed, signal lights did not override the llanekeeping assist and I literally had to fight with the steering wheel to enter the highway...car finally crossed the lines at a point where I was running out of ramp. Car has been returned to dealership numerous time, found fault codes with cameras and car was reprogrammed. Problem is not resolved and very dangerous. Audi corporate unresponsive. I have manually disabled the system. Note: reported date below is the date the car would not merge onto i87 south in albany ny. Numerous other occurences over the last several month. Audi albany service department has numerous repair orders. Car is in audi corporate remedation as a lemon but no conclusion yet. Car should be investigated and recalled serious hazard to pedestrians and bicyclists.
