VEHICLE HAD 300 MILES ON IT. ALL POWER WENT OUT IN THE VEHICLE INCLUDING THE STEERING GOING STRAIGHT 45MPH WITH MY SMALL CHILD IN THE CAR.

I WAS STOPPED AT A STOP LIGHT WITH MY FOOT ON THE BRAKE FOR ABOUT A MINUTE WHEN THE CAR SUDDENLY ACCELERATED AND LUNGED FORWARD.I APPLIED MORE PRESSURE TO THE BRAKE,ALL THE WAY TO THE FLOOR , BUT THE CAR WOULD NOT STOP. THE CAR IN FRONT OF ME IS THE ONLY THING THAT STOPPED THE CAR ,AS HE WAS STOPPED TOO. THE CAR THEN BOUNCED BACKWARD AND TURNED OFF BY ITSELF. I WAS ON A MAIN STREET AT A LIGHT. IT WAS FORTUNATE THAT ANOTHER CAR WAS STOPPED IN FRONT OF ME BECAUSE IT STOPPED THE CAR AND PREVENTED MY CAR FROM HITTING PEDESTRIANS.

Owner report 11700173 · 2025-11-18 (November 18, 2025)
On 09/16/25, I was exiting the Florida turnpike onto Sawgrass Highway via the exit ramp on exit 71. As I decelerated from 60 MPH to 35 MPH to match the speed of the exit ramp, I was in the left most lane in the two-lane exit ramp. My car spun out and I lost control of the vehicle, which caused the vehicle to spin through the two lanes of the ramp several times and ended up drifting onto the edge of the retention pond on the left of the exit ramp. I probably had spun around over three times and my car hung off the edge of the retention pond with…

Owner report 11607009 · 2024-08-07 (August 7, 2024)
My 2018 bmw 320 stalls and cuts off when I come to a stop. Very dangerous. It has cut off in the middle of the road. I have checked online to see if this is a common issue. Other bmw owners have reported this same issue. There has been a recall on other bmw models with this same issue from 2014-2018 for fuel system and fuel pump that may cause this issue. Letters were sent out I. January of 2022. My 2018 bmw 320si has not been included in this recall for some odd reason. When car shuts off a warning message appears on screen. One message stat…
