The electric motor of the new Cooper SE/Aceman range (U-series) is built on a newly developed EV platform and is considered very reliable according to early test reports. Reported issues are limited to software error messages and occasional charge flap sensor failures; mechanical drivetrain issues have not been documented so far.
E-MINI of the new era
184 hp electric motor with instant torque — in Go-Kart Mode a sporty soundtrack and sharper steering. Low centre of gravity compensates for the extra weight.
Engine Weaknesses 2
After several consecutive DC charging sessions, power output is throttled to 10–60 percent of rated power without any dashboard warning. The cause is overheating of the power electronics. Primarily affects long-distance journeys with multiple fast charges.
Symptoms: Noticeably reduced acceleration after DC charging on long trips, power recovers only slowly during normal driving
Early reports on U-era electric MINIs (Cooper E/SE F66, Aceman, Countryman E U25) show occasional charging issues and software errors that are addressed via OTA updates. Long-term reliability not yet established.
Symptoms: Error message during charging, reduced charging power, infotainment software crashes
Vehicle Weaknesses 4
Signal faults in the Continental MK-C2 integrated braking system can, in very rare cases, lead to increased brake pedal resistance and failure of ABS and DSC. Free system replacement.
The new infotainment system changes saved settings without user input. The problem is documented and is being resolved over time through software updates.
Owners report noticeably more hard plastic in visible areas and reduced convenience due to fewer physical controls. The perceived quality is below the predecessor F56.
The standard seats offer only limited lateral support and no extendable thigh support. The short seat cushion is particularly felt as uncomfortable on longer journeys.
