“Driving on the interstate in my june 2003 production Bmw Z4 3.0i roadster. The car suddenly dies at 65 MPH. The eml light comes on, brake lights come on, RPM needle surges, throttle is unresponsive, and the foot brakes are frozen and cannot be depressed. I was barely able to swerve off the interstate, across the service road, and into a parking lot where I had to use the hand brakes to get the car to stop completely.”
