Three days ago I was driving my 2014 mini Cooper s with 140,000 miles on it As I was driving it was losing power every time I stopped at a light it’s stalled but then it would immediately start again I finally made it home the Next day I went to start the car to take it to a mechanic I had no power the only electrical component that worked was the domelight that’s it I tried jumpstarting it it did not work I hooked up a charger to it left it for about three hours nothing I proceeded to remove the battery brought it to AutoZone to have it tested it was 89% What could the problem be?
RepairPal Certified shops can diagnose and repair your 2014 Mini Cooper Countryman. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
I'm only concerned that maybe during jump starting something happened to blow some fuses? Stalling and immediately restarting OK sounds more like engine performance issues rather than a problem with the battery and starting system. It's all really hard to know until you start checking things hands on.
AutoZone is not necessarily a great resource for testing batteries, but I guess it's all you have at the moment. And "89%" doesn't mean that the battery has the ability to sustain a load, just that it's the current state of charge.
I'd say you have multiple concerns, currently with the starting system -- maybe from the battery itself, and then also something engine performance related that will require troubleshooting.
