2006 Mini Cooper S with 66000 miles had a transmission failure that resulted in unsafe driving condition due to loss of forward propulsion while driving on highway.
Purchased 2006 Mini Cooper S brand new at a Mini dealer in boston. The vehicle has 108k highway miles. I had serviced the vehicle at the dealer until warranty ran out and transitioned to a national car care chain. I began to notice the vehicle slipping between second and third gear when traveling in stop and go traffic. I brought the car to my regular mechanic and they indicated that I should bring it to a transmission shop. Delivered the car to the shop and have been informed that my cvt transmission had failed and would need to be re-manufactured. I was also informed that my power steering pump is leaking and failing. The power steering fan had seized and was likely the cause of the power steering failure. The Mini dealership quoted me over 10k for the transmission replacement only did not inquire about power steering and there were no programs for customers in this situation. This cost is more than the car is worth. The transmission shop will do the repairs for 6k.
