About ten days ago, my 2025 Countryman ALL4 SE had exhibited a "jerking action" during low-speed acceleration. I was advised by Mini Customer Support to have my dealer run a computer diagnosis, as they had no other information on this type of behavior. I was advised that the scan found several faults in the front motor sensor. The remedy was to order a new sensor and a low-voltage battery cable. The dealer is waiting for the parts to arrive since they do not have them. I've had a loaner vehicle now for a week, and I'm being told the parts will arrive this week.
