The automated emergency braking randomly kicks in.. This has happened two times in the past 3 months. Nothing was around to cause the aeb to activate. This could have caused a serious accident if someone was driving behind me at the time. It jolted passengers in the car. The car came to a complete stop and nothing in the vicinity, no oncoming traffic, no pedestrians, no animals....

This issue has been happening since I got the car and is getting worse by the day. The car only has about 11,000 miles and I bought it when it had almost 10,000 miles. Something in the dashboard and behind the instrument panels (A/C Controls and User Screens) makes a lot of Vibration Noises/Sounds as the car is slowly accelerated or as we drive over some uneven road. It seems like there is something loose. And this is getting worse by the day.

The contact owns a 2020 Audi A6. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The brake, transmission, and several other unknown warning lights were illuminated. Additionally, the windows inadvertently rolled up and down while driving. The vehicle was towed to the dealer where it was diagnosed that the driver's and passenger's side rear seats sustained water damage, which caused an unknown electrical system component to malfunction.
