2019 AUDI E-TRON Forward Collision Avoidance Automatic Emergency Braking Problems

Dear Audi Product Safety Division and NHTSA Office of Defects Investigation, I am writing to formally document a safety defect in my 2019 Audi e-tron Prestige (VIN [XXX] ), which exhibits the same brake-system failure described in Audi’s brake-booster recall – Campaign 46P6 / NHTSA Recall 24V-621, despite Audi’s system not listing my VIN as covered. Vehicle Details Make/Model: 2019 Audi e-tron Prestige VIN: [XXX] Build Date: 05/19 (per manufacturer label) Mileage: [insert current mileage] Primary Location: Lynwood, Illinois Defect Summary My vehicle repeatedly displays: “Parking Brake Malfunction” and “Brake System Fault” warnings. A clicking noise or resistance when pressing/releasing the brake pedal. The brake pedal occasionally fails to return fully to its normal position. On one occasion, the vehicle rolled slightly while parked. These symptoms match those described in Audi’s recall 46P6, which involves improper assembly of the bolt connection between the brake-pedal input rod and brake-booster actuator rod....

Going about 50-55mph on dark road I have driven on for last six months in all conditions. Last night was normal dry conditions. I had cruise control and audi presense set to early detection. Suddenly the brakes engaged hard for a split second and then stopped. While this happened the cockpit display said "Audi pre sense" with a red circle icon below. After this the vehicle continued to drive without further incident. This is a common problem in various Audi models that would present various dangers. In particular I can't imagine what would happen if my pregnant wife was buckled in and the brakes suddenly slammed hard.

In a parking lot after backing out from the spot and entering car in drive mode - there was spontaneous, sudden, uncontrollable acceleration and spinning of 360 degree on extreme speed bringing the car in the same spot and stopped only with colliding with other parked vehicle on passanger side , pushing it further and damaging another parked car. During the spin process it front of the car first collided rear end of the car parked on driverside, than curb ,than the back of the car parked on passanger side. This entire event happened in fraction of a second without knowledge of the driver , immediately after the car was put in D mode from R mode . Suspecting some sort of TECHNICAL/ MECHANICAL FAILURE that should be further investigated for general safety. The car was regularly serviced at Audi dealership and there was on going issue with SOS SYSTEM...

I was traveling down a dip in the road and the Audi Pre Sense initiated emergency braking. There was no vehicle in front, the road ahead was totally clear. The vehicle behind me nearly ran into the back of my car.
