There was no specific event that led up to the problems. I bought the car brand new and problems began after about 4 months. The car "bucks" or "jerks" when gas pedal depressed to accelerate. Also when pulling out or when car is in reverse (ie for parking,etc). The first time I took the car to the dealership where it was purchased and they simply reset the computer. The problem persisted so I returned to the dealership. The second time we were told the problem was the clutch packs and they were replaced. The problem continued and the third time the mechatronic unit was replaced. The problem is still ongoing and I just dropped it off to the dealership again.
