What's wrong?
The high voltage battery housing on the 2020-2024 MINI Cooper Se is the case around the electric drive battery. It protects the battery cells and electrical connections from road splash, rainwater, and other moisture. It also helps keep the high voltage system isolated from the rest of the vehicle.
On affected vehicles, the sealing compound around the housing was not applied correctly during production. That leaves the joint between the housing halves vulnerable to water entering the battery. Moisture inside the battery can create isolation faults, meaning high voltage electricity is no longer contained where the system expects it. BMW linked the concern to thermal events after reviewing field incidents and production records.
If an isolation fault occurs, the vehicle displays a warning message to the driver. That message warns of the fault and tells the owner to have the vehicle inspected by a MINI service center.

What happens at the repair
At the MINI center, a MINI technician inspects and leak tests the high voltage battery housing, then repairs the battery as needed. The recall repair is free, with parts and labor covered. Out of pocket repairs already paid are handled through the MINI New Vehicle Limited Warranty program, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork for this battery issue.
