I came here to put my name into the list of people affected by this issue.
2015 BEV with 35,000 kilometers. I've owned the car for a little over 2 years. It was bought used from a BMW dealership just out of its 4 year warranty, CPO not offered. The AC failed in winter 2021, and the car threw a code for the HV cable. After the first 3 weeks were spent working on the HV issue, the dealership quoted me 3k to replace the compressor based on their diagnosis. When they went to perform the replacement they found the metal shavings, and got back to me with a quote around CAD$24,000 to repair. For the moment, I've asked them to reassemble it with the broken compressor.
The service manager offered to resolve my situation by forwarding me to the sales department. At the same time I've just paid $6000 to resolve the HV cable problem. I don't have any written documentation from BMW yet.
I budgeted that owning a BMW EV might have some expensive repairs, but not a repair that exceeds the price I paid for the car, and not for a car with such low mileage that was serviced on schedule.
