Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

NHTSA ID 11510859 · filed Mar 8, 2023

My son drives this car and the power steering went out twice on him while driving. I need to get the pump replaced via the recall, but the nearest location is 200 miles from me. It is not safe to drive this car that far and I would have to drop it off and make another trip to pick it up. Towing that far would cost a small fortune. I called every number and was transferred to several people to help with this issue. They say they can not and won't help me till I get the car to a dealership to fix it. One person from Mini told me I might be able to go to a certified mechanic but when I asked the next person they said it had to be a dealership. I spent two days on the phone with several people from Mini and no one was willing to offer a solution. I drive this car to get the recall fixed and something happens and the car wrecks, or worse someone is killed, who would it be on then? No happy about this at all.

The transmission will cycle first through third and when it tries to go into 4th it slips and will not operate higher gears it caused me to lose my forward drive momentum as I was switching lanes and the car I was getting in front of almost ran into me.

MY 2005 MINI COOPER CONVERTIBLE NEEDS THE TRANSMISSION REPLACED. MY CAR HAS ONLY 92,000 MILES AND IT IS UNFAIR THAT ALREADY IT HAS TO BE REPLACE AT A RIDICULOUS COST. THERE WAS A CLASS ACTION LAW SUIT WITH BMW/MINI FOR THE TRANSMISSION THAT WENT WRONG. THERE ARE MANY PEOPLE BESIDES MYSELF WHO WHERE NOT NOTIFIED OF THIS AND WERE LEFT OUT. MINI COOPER SHOULD RECALL THE TRANSMISSIONS .THERE ARE MANY FORUMS OF MINI COOPER OWNERS WHO ARE OUTRAGED AND HAVE SIMILAR SITUATIONS. PLEASE CONSIDER AND MAKE THIS COMPANY RECALL THE TRANSMISSIONS. THANK YOU *TR

HI, I'M WRITING TO REPORT THAT MY 2005 MINI COOPER, WITH LESS THAN 43K MILES IS IN NEED OF A THIRD TRANSMISSION. I NEARLY DID NOT MAKE IT HOME ONE EVENING BECAUSE THE JERKING MOTION THE CAR WAS MAKING AND BECAUSE THE ENGINE JUST FELT LIKE IT WAS GOING TO SHUT OFF. I NEARLY STALLED ON THE HIGHWAY, WHILE IN TRAFFIC. THE FIRST TRANSMISSION, WHILE UNDER WARRANTY WAS REPLACED IN NOVEMBER 2007 AT 28K MILES. ON 12/16/08, I HAD AN ACCIDENT WHERE THE TRANSMISSION PAN AMONG OTHER THINGS HAD TO BE REPLACED. IT WAS THE ONLY KNOWN DAMAGE CAUSED TO THE TRANSMISSION. THE AUTO BODY AND PAINT SHOP THAT I CONTRACTED WITH DID NOT KNOW HOW TO FILL THE TRANSMISSION FLUID AND THEREFORE THE CAR HAD TO BE TOWED THE LOCAL MINI COOPER DEALERSHIP. THEY PERFORMED THAT PIECE OF IT. NOW, THE DEALER IS TELLING ME I NEED A NEW TRANSMISSION AND THE CAR IS OUT OF WARRANTY. THE DEALERSHIP ALSO STATES THEY DON'T KNOW IF THE TRANSMISSION DAMAGE WAS A RESIDUAL OF THE ACCIDENT OR NOT AND THEREFORE, WERE TRYING TO OPEN UP THE OLD INSURANCE CLAIM FROM JANUARY 2009. HOWEVER, MY INSURANCE COMPANY DOES NOT WANT TO PAY FOR THE NEW TRANSMISSION BECAUSE THEY STATE THE REPAIRS FROM THE ACCIDENT $7,888.70, PLUS THE COST OF A NEW TRANSMISSION, AROUND 8K WILL BE MORE THAN THE VALUE OF THE CAR. SO, WHO SHOULD PAY FOR THIS NEW TRANSMISSION, THE DEALER, THE AUTO BODY SHOP (WHOM DID NO WORK ON THE TRANSMISSION, SEEMINGLY) OR ME? HOW DO I KNOW, THIS IS NOT JUST ANOTHER BAD TRANSMISSION? THERE IS NO WAY TO TELL ON A MINI COOPER (NO WAY TO CHECK) TRANSMISSION FLUID AND NO INDICATOR LIGHT CAME ON. *TR
