No incident occurred. On October 18th we received a high voltage battery recall notice for this car. Apparently there were some thermal events (fires) and BMW has released software to help protect the car from such an event. We have been trying to get in touch with MINI, and just recently found that the dealer closed. They left their answering machine online for about a month after. The local BMW dealer says that they cannot perform the update (MINI USA requested we ask them). MINI USA now says that the car must be trucked 300 miles away to the closest dealer. The car cannot even be driven…
Digital instrument cluster of electric Mini SE (includes speedometer and battery/range information) turns off without warning while driving and does not turn back on until car is powered down for over half an hour. This has happened more than ten times. Vehicle was inspected by MINI dealer locally and no obvious equipment defect was identified, although they were able to replicate it happening. After disassembly and reassembly by dealer, issue stopped for about two weeks after car was returned to owner. Now it has begun again, to the point of turning off within a few minutes of driving every…
The car completely lost steering in traffic. I brought it back to the Mini dealership, they informed me this is a known issue for Mini Coopers equipped with the click-and-play system, and they needed to re-wire the click-and-play to fix it. However Mini decided this should not be a recall. I strongly disagree with Mini's assessment considering losing steering on the road could cause severe accidents.
After work, I started the car in a parking lot. Before leaving, a fire started under the hood behind the passenger side headlight. After using the jaws of life to take off the hood, the fire department contained the fire. No injuries. There was extensive damage to the right front. The contents were all smoke damaged. Neighboring cars were not damaged. The car has been totaled.
On October 4, 2022, the Mini Cooper hardtop 4 door was hit in a head-on collision by a driver who was going at least 40 MPH, possibly more. The car that hit the Cooper was a Toyota Prius. All the Prious' airbags deployed. No airbags deployed on the Mini Cooper hardtop 4 door. None. The Mini Cooper, after assessment, was considered to be a total loss.
Tire model is: Hankook Ventus S1 Evo Z 225/35R18 87Y. Failure started when vehicle turned the "CHECK TIRE PRESSURE" alert on while driving. Pressure started to drop from 32 lbs to 16 lbs in about 15 minutes. Worth to note: no pot hole or any other object was hit during the day of the incident; or even previous days. After stopping, I noticed that the failure occurred in the inner face of the tire. Inner face was pretty degraded and inner treads were visible. A 15 inch long breakage line was visible. Car has 18k miles on it. When comparing the tire that failed to the rest, its degradation was…
The night of October 24th, while I was driving my CID back screen went to black and there were messages displayed in white color. Bootloader 11.035.000/ FFW 1.8.3 Dec 5 2017 Next line is displayed HWEL:42E5 2.1.5 Followed by a large white bar This display stays on even after lock the car.

Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports. To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
