NHTSA Complaint #11512914 — 2023 AUDI A4

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.
