FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The Audi Pre-sense is activated by weather. I was driving during a thunderstorm and Audi Presence activated causing the car to come to a hard stop due to precipitation. It happened again backing out of my driveway the Audi Pre-sense was activated and the car came to a hard stop. I thought I had back into another vehicle. This is very dangerous.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
The car has had multiple issues with warning lights and malfunctioning systems. Including : 1.Child locks 2.Every single component of the ADAS 3. Emergency services being activated at least a few times a month - this is an SOS for emergency 911 service. The repeated, continuous and mostly false warning lights are a driving distraction that can easily cause an accident. I have photos of all warning lights coming on in the vehicle. The dealership has repeated stated that they couldn't reproduce the problem even though pictures were provided and the car is still under the original warranty period. The latest attempt to fix the vehicle was to replace the sensors on the front of the vehicle. This solution was only attempted after the 4th report of the problem to the dealership where the car was serviced under the original manufacturers warranty

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Camera system does not work sometimes or only some of the cameras work sometimes. Dealer agrees there is a problem, but no fix is currently available. I have noted that other 2022 Audi A6 models have been recalled for this reason. The problem first occurred about 2 months ago. Sometimes the cameras are working and sometimes you get a black screen or a partial black screen. The problem is that when the cameras don't work, you also don't get a visual indication of cross traffic when backing out of a parking space.

ELECTRICAL SYSTEM
Vehicle had electrical system malfunction. Vehicle provided an electrical system malfunction and vehicle starting system malfunction warning message a few days prior to the incident. Vehicle has approximately 20.5K miles on odometer. Before I was able to bring it to service, the electrical system malfunction message became more severe and turned from yellow to red. While driving, the vehicle progressively shut down ABS, lane departure, and other systems and gave a transmission warning message. Eventually, the car lost power and I was left stranded at the side of the road.

STEERING, ELECTRICAL SYSTEM, ENGINE
Car reported an engine restarter issue (with battery symbol) and recommended to contact the dealer. Car next shut down automatic restart system, and air conditioning stopped working. Within a short period of time (same day), the car listed a red battery symbol and advised to stop the car. After doing so and contacting the Audi roadside, the car was listing a series of issues on multiple symptoms while also saying in the warning message "still okay to drive". These systems included steering, braking, and what seemed to be other sensors the car powers. Finally (and within 5 minutes of the previous message of being okay to drive), the warnings were continuous and started including the transmission. The car stopped accelerating (we were on the expressway) and we thankfully got to the side of the road. This was an enormously dangerous situation as the car became fully disabled and we were subject to limited options of relief from a major traffic area. Within 30 minutes of being disabled, no electrical charge was present in the car, including emergency flashers, making the situation more dangerous as it was nighttime, so we had to abandon the car and walk down the expressway to find a hotel. Could not even put the car in neutral for the tow. Service is initially reporting a failure of the restart generator. This appears to be an alarmingly common issue with Audis.

ELECTRICAL SYSTEM
Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, electrical system, start/stop, etc) then 1 minute later transmission failure and engine failure imminent. After a minute or two 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 in the center median of an expressway and contacted the dealer. Flatbed towed to dealer who stated most likely the generator between the lithium battery bank and gas engine failed. They have seen several in this year for A6 and A7's with mild hybrid engines. I was 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. After having car towed to Audi dealer, they proceeded to tell me it was the starter/generator and the part was on back order for two to three months.

STRUCTURE:BODY
Sunroof spontaneously shattered while driving. No other cars around when this occurred. Caused a very loud BANG. Was driving on the freeway when this occurred. Dealer would not confirm issue was spontaneous - felt something must have hit the car to cause this. No defined impact location on roof. Also, roof glass was pushed up in the middle instead of down like would be expected if something hit it from the outside. No warning before it occurred.
