This 2021 Audi SQ8 vehicle was purchased new. The vehicle features an automatic engine stop/start feature which is intended to enhance vehicle fuel economy. The incident(s) include: (1) multiple instances when slowing to a stop and the stop/start feature turned off the vehicle engine before the vehicle has come to a stop, leaving the vehicle to "coast" to a complete stop but without the aid of power steering, full braking capacity and ordinary functionality of a running engine; (2) one instance when parking and the /start feature turned off the vehicle engine, in a drive aisle of a busy plaza parking lot, after I stopped and moved the transmission to reverse in order to back into a parking space; and (3) multiple failures to quickly start and permit required fast acceleration when the start/stop feature would not turn on the engine on demand to permit quick acceleration needed to safely cross a 2 lane roadway in front of approaching traffic from the opposite direction.

MMI system stops working all of a sudden. This has happened multiple times and especially when it takes updates on its own. When called customer service they referred to the dealer stating they cannot do anything. Right after my call with them the car starts functioning back to normal. When I took it to the dealer for service and the problem, Dealer mentioned Audi has received complaints about the new models being affected and is aware of the problem but there is no software patch released yet. Its dangerous to drive as all functions are are turned off including cameras, Bluetooth, collision warning, blind spot, lane departure, music and more (except the engine running). Another issue is with its auto engine stop function, is when you are at a red light with a complete stop and when the light turns green and you are ready to move, the car takes a second or two to get the engine started and pulls back a little. Also the transmission pulls rough at that time of start. Am not sure why this is happening. The car pulls back even when the auto engine stop function is turned off.
