general problems of the 2010 Mini Cooper S Clubman

6/21/2018, my 2010 Mini cooper clubman s developed serious defects. I drove my car on the leftmost lane of three-lane boston turnpike. Close to a traffic light, I braked to decelerate vehicle but the engine suddenly died without warning, while car was in motion. Both battery and starter worked. I tried multiple times to restart the engine in failure. I blocked traffic during rush-hour. Several cars took across road curb and passed to my left. It made me and my son in dangerous situations. Until a truck driver came to help me to push my car off road. After diagnosis and analysis in local auto shop, mechanic found out the vehicle computer engine control module (ecm) was faulty, not supplying power to the ignition coils. I was charged $2298. 13 to replace defective ecm and $150 for the towing service. The warranty has expired but I believe I am still entitled to a free repair because the existence of such a serious defect in a car which has only run a low mileage of 47,812 miles indicates it was not of acceptable quality. I am a careful and conscientious owner, as the general condition of the car shows. I have not done anything to the car to cause this defect. The defective component is not moving mechanical parts. It is supposed that it has much longer life time. The defect forced me to spend thousands of dollars on replacement costs. To obtain BMW reimbursement in full, I called 1. 866. Ask. Mini (275-6464) and talked to a representative and an escalation manager. The escalation manager emphasized that my car was not repaired at a Mini service center (dealer). If my car was repaired at Mini center, they would arrange a solution however my broken car was far from dealers in either peabody or boston. I file a defect petition to NHTSA. I request the agency do a basic review of my concern and provide a written decision on whether it will begin the in-depth investigation.
