I drove an automatic 2013 certified MINICooper off the lot with 33K prior miles. After less than a week, and after only driving a total of 254 miles, the accelerator failed in the middle of an intersection. I did not loose all power, the gas pedal just quit responding while I was driving. All other systems in the car seemed fully responsive/operational with exception to the accelerator. The engine did not rev and the car did not respond to the accelerator even when it was pushed fully down. My car was manually pushed out of the intersection/traffic with help by the person behind me. After safely to the side of the road, I turned off the car. After about 5 minutes I restarted the car and the gas pedal was operational. The following day I drove the car back to the dealer without incident. They re-checked the certification items and were not able to diagnose the problem. Their error readers did not detect any codes. Perplexed- they sent the information to their technical engineering department. The engineers claim that it is a needed software update that caused the accelerator failure while the vehicle was in motion. The engineers are asking that the MINIservice department update the software and drive a bit to test the vehicle. The situation that the needed software update caused is dangerous. I have seen posts from other MINICooper drivers who have/are experiencing this issue- yet there are no recalls or known service bulletins for the hazardous problem. I did notify MINIusa (corporate) of the accelerator failure. Notes: The car was very recently fully serviced/certified with no know problems, I had fuel, I was in drive, the car was in motion, I was attempting to make a left turn in a residential intersection, I was in the process of accelerating when the gas pedal failed to respond further- I was immobilized in the middle of an intersection.
