2022 Audi Audi A4Transmission & drivetrainEngine & cooling

My wife drove back home from work around 5:45 PM EST on March 2, 2026 and parked the car in the garage as always. She parked and turned off the car and got out to check the mail from the mailbox across the street. The music stopped when she turned off the car ignition after putting the transmission in park position and opened the door to get out. She walked to the mailbox and heard a loud bang. She turned around and found the car in the swale between our and our neighbor's property against our neighbor's tree. The...

She drove it back into the garage and parked again. She turned it off and waited in the car for few minutes to check. She got out of the car keeping the garage door open and waited for few more minutes before closing the garage door.

I leased a 2023 Audi A4 with 0 miles. At ~10,000 miles my car automatically shut down electronically I have photo evidence of this. This happened again recently at ~45,000 miles, I almost got into a severe car accident and possibly died. This happened on the highway driving in the left lane. I tried to remedy this situation before and was ignored by Aud's service center. I am scared I can die on the road and am taking in the car for repeat service tomorrow.

Since I bought this car in June 2023, I've had two instances where the presence feature malfunctioned when there was no danger of any accident. I've had one instance when all of the safety sensors illuminated at the same time while driving. Finally, this past Saturday, my car malfunctioned and died/ turned off while I was driving. It took a minute or so to get the car started. A malfunction notice illuminated. The area traffic is congested, so people honking at me but nobody hit me. Luckily, I was not on the freeway.

2023 Audi Audi A4Engine & cooling

My brand new car stalled in the middle of traffic; as I proceeded to step on the gas peddle after yielding -- the car completely stoped as is I hit a wall, it jerk roughly and completely stopped. At first I thought someone rear-ended me, but that wasn't the case, the car just stalled, and the "Audi Pressure Sensor" warning flashed across the screen in Bright Big Letters for a few seconds, and once the waring went away, the car turned back on. This event happened twice, about 40 days apart. My life was at risk...

because if I was on the expressway, the complete stop of vehicle could have cause an accident. The car completely stoped, it doesn't slow down, it just stoped roughly, very dangerous situation. I called the dealer and I have an appointment in 2 days, meanwhile I won't take the car on the expressway, or drive it if I don't have to. I'm frighted the 3rd time I won't be so lucky and someone may hit me from behind.

2022 Audi Audi A4Engine & cooling

Engine auto start / stop engages before vehicle comes to complete stop and when on a road with an incline the engine shuts off and all forward momentum is lost causing the vehicle to roll backwards. The closest description I can think of is that it feels like the automatic transmission is slipping which should not happen on a car with 2,000 miles on it. I previously drove a 2019 A4 and the older model did not have this issue. Safety issue is that engine shuts off prematurely and when on an incline the car can...

roll backwards. Component is available for inspection and there is warning light/indication. Has not been taken to dealer yet but plan to next week. Reporting it now due to: 1) how jarring it is 2) it has happened multiple times since taking possession of the car in December 3) I have not experienced this with older Audi's I have owned or driven as service loaners 4) there is no way to permanently disable auto start/stop offered by Audi USA and requires after market software changes
