“WHEN VEHICLE IN MOTION ON MAJOR ROADWAY, LOSS OF POWER AND GOES INTO LIMP MODE. YELLOW WRENCH LIGHTS UP. VEHICLE DOES NOT RESPOND TO THROTTLE. I HAVE TO SHUT OFF VEHICLE AND TURN IT BACK ON . THERE IS NO DTC CODE WHEN CHECKED. I WAS ALMOST REAR ENDED WITH MY CHILDREN IN THE VEHICLE AT TIME OF INCIDENT. CAR LOSES POWER AND RAPIDLY DECELERATES WITHIN 5 SECONDS. THERE IS ZERO TIME TO PULL OFF THE ROAD WHICH PUT US AT HIGH RISK OF BEING REAR ENDED. THIS IS A LIFE/ROAD SAFETY HAZARD”
