2013 AUDI Q5 with 70290.0 miles
Incident date: 5/9/20 mileage: 70,290 miles summary: i reversed out of parking space, shifted my car into drive, and my car abruptly hesitated, decelerated, resisted, and jerked upon engaging the gas pedal; a series of multiple warning/indicator lights simultaneously flashed on the obd screen while my car was in motion. The car continued to decelerate, jerk & hesitate.Messages referenced hybrid, malfunction, electronic, inoperable, loss of ability to control steering, steering power, danger, hazard, engine, stabilization, driving, power. I attempted to accelerate from a stop sign to cross a 4 lane intersection of moving traffic. Upon pressing the gas pedal to cross the traffic intersection, my car would hesitated to accelerate, and more abruptly jerked and hesitated - like i was driving a manual transmission that was stalling out/stuck in the wrong gear.The more i tried to accelerate across the 4 lanes of moving traffic, the more severely the car resisted, jerked, hesitated, and fluctuated in power. I could've been t-boned by another vehicle and seriously injured, as the speed limit on both sides of this traffic intersection is 45mph. I was informed by the Audi dealership that i need a brand new transmission due to 'internal parts failure.' i was also informed the 'condition and level of transmission fluid' requires an entirely new transmission. The following diagnostic codes were provided by the dealership: P0AB900,P060A00,P279700,U040200. According to Audi, my car now needs a whole new transmission and has 'burned' transmission fluid due to an 'internal parts failure' at 70,290 miles.The transmission replacement and labor is approx $27k. I recently learned the transmission mechatronics was replaced by another Audi dealership in aug 16' and the mileage was approximately 22kmiles. I purchased the vehicle in jan 17', with approx. 26kmiles. More detail in pdf.
