started with lights not going off once i cut car off, then windshield wipers would come on it's on, then check engine warning lights, check fuel pump and check rear bulbs lights and several other warning lights would stay on, finally it got to it wouldn't crack until after three or four tries, then it started cutting off while driving, then I would have to wait for 30 min. or more, then it would crank back up. now it won't crack at all. I've been waiting on this recall since 5/12/23 recall #23V337. Please advise and Help!!

This car was maintained, by Mini and BMW authorized mechanics and only had OEM parts installed and followed management of vehicle as directed by manufacturer, throughout its history. It was always driven and kept in moderate weather conditions, no extreme heat, cold, wet, or speeds. Used almost daily for 30-60 minute commutes. Just after 100K miles, total engine failure was suddenly experienced on the freeway, due to combustion in two valves, damaging two cylinders and sudden leaking of the exhaust system under the hood. The manufacturer, BWM, has been shown evidence of malfunctioning of the four cylinder engine and will not show evidence of their grounds for why they will not take responsibility.

HANDBRAKE HARNESS NOT ROUTED AS DESIGNED. FROM THE PICTURE YOU CAN SEE THE HARNESS NOT INSIDE THE CLIP. THIS MAKES THE HANDBRAKE HARNESS SHORT FROM POINT TO POINT. WHICH WILL LEAD TO MY REAR PASSENGER SIDE BRAKE ALWAYS ON. AND ALSO, IT WILL CAUSE A SERIOUS SAFETY ISSUE IF I WANT TO USE MY HANDBRAKE TO STOP MY VEHICLE. THE FORCE APPLIED ON PASSENGER SIDE IS WAY MORE THAN DRIVE SIDE ( IT WAS INSTALLED CORRECTLY ) . AND IT MAY LEAD MY PASSENGER SIDE HANDBRAKE WIRING HARNESS BROKEN ( BECAUSE OF THE INCORRECT ROUTING ) I FOUND IT OUT WHEN MY BRAKE LIGHT IN ON. MY FRONT BRAKE STILL WORKING FOR ANOTHER 1100 MILES WHILE MY REAR BRAKE SENSOR TELL ME I NEED TO CHANGE MY BRAKE . WE CHANGE THE REAR PASSENGER BRAKE AND FOUND OUT ITS DIFFICULT TO CLIP THE HANDBRAKE WIRING HARNESS TO RIGHT HOLE. THEN WE TRACK THE WIRING DONE. IT'S SHOCKS ME . THE ROUTING IS 100% INCORRECT. YOU CAN SEE THE CORRECT HANDBRAKE HOLE IS EMPTY.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Mini Cooper Hardtop verdict →
