NHTSA Complaint #11651509 — 2025 BMW I4 EDRIVE40

On March 23, after driving approx 2 miles, I was at a red light. The light turned green and I began accelerating. There was a loud "bang" from under the car toward the rear, the car abruptly halted, the displays turned red with a message (all caps) DO NOT DRIVE. I power cycled the car a few times and the error cleared, but my state-of-charge had dropped from 77 to 59%. I drove the car the 1 mile home and called BMW Roadside Assistance. The rep asked for permission to pull logs from the car, told me he would be sending a flatbed Monday morning and advised me, in no uncertain terms, DO NOT DRIVE THE CAR. I asked if I could pull the car out of the driveway and he said no; he would send skids with the driver. Friday afternoon I was advised there was nothing wrong and to pick up the car. The work order is blaming an LA DWP 50KWh charger I had used 2 days prior to charge from 65 to 81% and recommends avoiding this charger. Just to be clear, I charged 15% on 3/21 and the car went "bang" on 3/23, and that was the fault of the charger.
