Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When driving 40 MPH or more, the engine stalls and the unit in the dashboard that contains the odometer and speed, begins to turn white in color. It appears the software error within the engine control unit causes the vehicle to stall when driving at a certain speed or when I am coasting to a stop, such as at a traffic light. My vehicle begins to shut-down in the mist of my driving at 40 MPH or more, however, when I put my foot on the brake, the engine picks up speed. …”
