As I was easing my 2024 BMW i4 xDrive40 onto Church Street from a cross street on May 11, 2026, my car suddenly accelerated and crashed into the car in front of me. The acceleration was "un-commanded." The accident occured a bit before 2:20 pm. Driving conditions were ideal. I had the car in Eco Mode, and I was using one-pedal driving (braking when one eases up on the accelerator pedal). When the car becan accelerating. I believe that I had time to depress the brakes, but it was to no avail. There were no reportable injuries and no police report. My car has automatic emergency braking, and on two separate occasions the car braked suddenly when "it" thought that I was approaching a car to quickly. It did not function in this instance to stop my car from crashing into the car in front of me. I had never previously seen the car behave like this. I had owned the car since its initial purchase in August of 2024.

On July 4th, 2026 we were driving home in a storm. The windshield wipers failed while in the automatic setting, completely shutting off, creating a safety hazard. We pulled to the side of the road and restarted the vehicle. Afther the reboot they had resarted, but agian failed within ten minutes. We pulled over again giving the car more time to cool/reset and contacted BMWs internal SOS service. They could not hear due to the rain coming down on the car. Eventually we were able to proceed home with the wipers on a low setting. We took the vehicle to the dealership. They were unable to reproduce the defect, calling it an anomally in one video. The BMW techs are the only one to have inspected the vehicle. As for warnings, there were none. It was just a system failure mid-storm with no proceeded or forwarned error codes.
