ODI #11341298

Incident: July 23, 2020 · Filed: July 24, 2020

LOSS OF ALL VEHICLE POWER WHILE TRAVELING ON THE FREEWAY AT HIGHWAY SPEEDS. VEHICLE CHECK ENGINE, POWER LIMITED, AND ELECTRIC MOTOR OVERHEAT WARNING LIGHTS COME ON. THE COMBUSTION ENGINE WILL NOT START, AND BATTERY POWER AVAILABILITY GOES TO ZERO. THIS IS VERY DANGEROUS TO PUBLIC HEALTH AND SAFETY DUE TO INSTANTANEOUS LOSS OF COMBUSTION ENGINE AND ELECTRIC BATTERY POWER WHILE IN FAST-MOVING HIGHWAY TRAFFIC. THERE ARE SEVERAL INSTANCES OF THIS SAME PROBLEM OCCURRING IN MANY CADILLAC OWNERS FORUMS, SO GENERAL MOTORS KNOWS THERE IS A PROBLEM WITH THEIR CT6 PHEV TRANSMISSIONS. THE FIX SEEMS TO BE REPLACING THE TRANSMISSION DUE TO A BAD CLUTCH PACK, BUT PEOPLE COULD GET HURT IF THIS ISSUE IS ALLOWED TO CONTINUE WITHOUT A PERMANENT SOLUTION.
