There are 3 owner-reported electrical system complaints for the 2021 MINI Cooperin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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 day, rendering car unusable as driver has no other speedometer in vehicle. After sitting for half an hour, the instrument cluster will turn on when the car is turned on next, only to go out again after a few minutes of driving. Other electronics in car do not appear affected and car operates normally.

Neighboring cars were not damaged. The car has been totaled.
