Power train
14 reports1 related recall
“Engine motor mount sheared, allowing motor to interact with and bounce directly on the frame, and stressing the other connections and components. Dealer indicated this is a very common problem for this car model and is likely a design issue, and even had another example of a sheared mount on display in order to show others with the same issue.”
Engine
11 reports
“The fuse box JBE module has a Quality Assurance problem with a solder connection to the NEC low pressure fuel relay. This is a known issue with BMW/Mini. The car suddenly stalls without warning. If the driver is not keen or if traffic patterns do not allow, the car can be left in very dangerous situations on the highway or in the middle of intersection. The repair for this problem is widely distributed online via blogs and YouTube, but replacement modules are $1500 (part only) and these modules are not available until at least October 2023. There are no warning lights or other warnings prior to the incident. While I am not aware of any serious injuries, it is only a matter of time before someone is t-boned at an intersections. This part MUST be immediately recalled due to the safety risk. The images below show the JBE fuse box housing as well as the PCB where the cold solder joint can be seen. I have circled the cold solder joint in the close up picture.”
Electrical system
8 reports1 fire
“The contact owns a 2014 Mini Cooper. The contact stated that the front driver's side and passenger’s side doors and windows failed to properly close. The vehicle was taken to the local mechanic who diagnosed the vehicle and determined that the failure was caused by a faulty foot well module which caused the electrical power windows to malfunction and the doors to not properly close. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 23V337000 (ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 80,000.”

“PASSENGER AIRBAG SENSOR ISSUE, I HAVE SEEN THIS REPORTED IN OTHER MINI COOPERS THAT WERE RECALLED BUT MY SPECIFIC MODEL WAS NOT. I WANT TO BE SURE ALL APPLICABLE VEHICLES ARE INCLUDED IN THE RECALL FOR THE SAFETY OF MYSELF AND OTHER MINI OWNERS. I HAVE NO AIRBAG FUNCTION RIGHT NOW AND BOTH MY DRIVER AND PASSENGER SIDE AIRBAG LIGHTS ARE ON. MY MECHANIC STATED THAT I WOULD NEED TO REPLACE THE PASSENGER SEAT SENSOR AT THE LEAST.”
