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.

The car was purchased in 2019, brand new from Audi dealership. Last service showed a serious issue: REPLACE WATER PUMP VACUUM LINES WITH SOLENOIDS AND VACUUM RESERVOIR. Dealership claims out of warranty and wants to charge $5000. VW settled class action lawsuit with consumers due to faulty water pump, and there is a Technical service bulletin dated 11/21/2023 that states the water pump leaks coolant and needs to be repaired. Consumer should have been made aware that vehicle was at risk of faulty water pump that could have been replaced at time of bulletin issue because it would have been under the 4 year mark.

Rearview camera (or various combinations of between 1 and 4 of the surround view cameras -- no rhyme or reason to which camera(s) fail in a given incident) frequently fails and displays a black screen instead of rearward facing view. This happens roughly one of every ten times I start my car, and is resolved only after I turn my car off, lock it, and leave it alone for several minutes. This has been the case since the car was new to me (I am the second owner of the vehicle, having purchased it 8 months and 10k miles after the original owner). This severely compromises rearward visibility and is in direct violation of Federal Motor Vehicle Safety Standard No. 111. Without the mandated backup camera, I am unable to see immediately behind my vehicle, increasing the risk of a collision with a pedestrian, another vehicle, or an animal/other object. The problem has been reproduced by two separate Audi dealers (Audi Marin and Audi Palo Alto), but they have been unable to resolve the issue upon repeated inspection of my vehicle. There are no warning lamps or errors prior to the failure. The only indication of failure is when I shift into reverse and see a black screen. This issue is consistent with other owners' experiences (see [XXX] ) who own vehicles on the same infotainment infrastructure (2019-2020 Audi A6/A7/A8/Q7/Q8). Similarly, it is consistent with the issue underpinning Compliance Recall 91DZ, affecting the same vehicles of the 2021 model year onward.

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.
