2019 Audi A6

Yellow battery indicator light came on while driving car in 35 degree weather after a week of sitting in garage (holidays). I pulled over, read the manual and it said this could cause battery light to illuminate. I called the dealership service to ask them, they said possible reason. I decided to drive across city to dealership, 25 minutes away. On HOV lane, red warning lights flashing to pull over then 5 seconds later everything went black. No electrical, no engine, car died. VERY DANGEROUS!! Read later that this has been happening on Audi A6 (& other models) for 2+ years. Towed to dealership and they have had 1.5 weeks and still not fixed.

After heavy down pour, the car was driven while the streets were still very wet. The car was driven through a 2 - 3 inch puddle of water that lasted less than 1 second, which caused a splash to the passenger side of the car, (the middle of the street did not have an accumulation of water) and within 30 secs caused the power steering warning light came on. This was not a flooded street, just the normal accumulation of water on the side of a residential curbed street. The steering immediately started to stiffen up and required increased effort to turn the steering wheel. The first warning lamp was yellow and stated that continued driving was still allowed, but after about 3 min the lamp turned red, and the message indicated "Steering malfunction, Do not drive vehicle". This occurred on a street where the speed limit was 30 mph, so safety at that time was not a big issue, but if this had happened on street where increased speed and more turning was required, safety could be a big issue if this happened suddenly. I was able to get the car to a nearby shop within 5 min, and the next day moved the car to the Audi West Houston. Audi has identified the power steering rack as faulty is in the process of replacing the electric power steering rack assembly. This car is a 2019 AUDI A6 with only 41k miles.

The car couldn't start and stopped abruptly on the way through bunches of errors on the dashboard with check engine light and steering was firm and could not lock the Car or open the door Here are the warning list for 2019 Audi A6: Electrical system malfunction Electrical system malfunction Parking aid malfunction Transmission malfunction Rear spoiler malfunction Drive system: malfunction Traction control malfunction Tire pressure monitoring system malfunction Parking brake malfunction Automatic start/stop system malfunction Start/stop system malfunction

This is my SECOND entry/complaint regarding the same EXTREMELY DANGEROUS steering malfunction. While driving my 2019 A6 (this time alone) in heavy rain the same warning message was displayed. The warning stated: steering malfunction, please stop the vehicle!. At which point the power steering locked-up & the engine powered down. As a result, I was unable to steer the vehicle. One again I was able to exit the highway safely. Being close to home with only a few turns, I was able to “limp” the car home, parked in my driveway and contacted Audi. Currently it’s at Nyack Audi awaiting service on Monday 9/11. This is a huge safety issue and needs to be addressed. Doing a bit of online research & reading countless Audi blogs, I found out this to be a common issue with other Audis while driving in the rain. Fist time this occurred was 6/16/22, driving a 2016 S6. Tracking # for that entry is 11543563

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.

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.

The car displayed a warning that the electrical system had a fault and to contact service. I then contacted service and they said to drive it to the dealer as it sounded like a known issue with the generator/starter and 48V system. On the way to the dealership, the warnings continued and then various systems began shutting down, including the steering and the transmission. I was going at a relatively slow speed on a side street at the time, which was fortunate, as the car locked up all four wheels and had no steering and the engine quit. Thankfully it was a side street. If this was a major street or highway, it quite likely could have caused a serious accident or injury. In contacting Audi USA, they do not have parts available to fix this issue, and the dealership confirmed that they are unable to fix the car at this time.
