NHTSA Complaint #11461619 — 2018 CHEVROLET BOLT EV

INTERMITTENT EXTREME VIBRATIONS OF THE VEHICLE WHEN DRIVING. THIS ISSUE COME AND GOES WITH OUT ANY WARNING LIGHTS DISPLAYING. THE VIBRATIONS ARE SO EXTREME THAT I MUST SLOW DOWN TO 30 MILES PER HOUR OUR LESS TO MAINTAIN CONTROLL. I TOOK THE VEHICLE TO THE LOCAL DEALERSHIP AND LEFT IT FOR A EWEEK AND THEY COULD NEVER REPRODUCE THE PROBLEM. THE PROBLEM HAS OCCURED SEVERAL TIMES SINCE TAKING THE VEHICLE TO THE DEALERSHIP EARLY 2022. IF YOU DRIVE THE VEHICLE LONG ENOUGH IT WILL USUALLY STOP THE VIBRATIONS AND IF YOU TURN OFF THE VEHICLE AND LET SIT OVERNIGHT; THE VIBRATIONS ARE NOT PRESENT WHEN YOU DRIVE THE VEHICLE THE NEXT MORNING. IF YOU TURN OFF THE VEHICLE FOR JUST A FEW MINUTES THE VIBRATIONS ARE STILL THERE, BUT MNAY STOP IF YOU CAN DRIVE IT LOGER. I CAN NOT TELL IF THE PROBLEM IS THE BRAKES OR THE DRIVE TRAIN. I DO NOT KNOW IF THE VEHICLE MAY JUST LOCK UP IN THE MIDDLE OF TRAFFIC.
