NHTSA Complaint #11365989 — 2012 CHEVROLET VOLT

WHILE DRIVING SUDDEN LOSS OF POWER HAVING TO BASICALLY DEPRESS GAS PEDAL TO MAINTAIN SPEED WHILE SIMULTANEOUSLY RECEIVING "REDUCED PROPULSION ERROR". DEALER CLEARED ERROR AND DID A REPROGRAM. AFTER PICKING UP VEHICLE RANGE WAS REDUCED APPROXIMATELY 1/3RD BUT CAR RAN. SHAME ON ME FOR NOT BEING MORE FORCEFUL ABOUT RANGE REDUCTION BECAUSE THIS BATTERY WAS DEFECTIVE. THIS SUMMER JUNE 2020 COMPLAINED ABOUT REDUCED RANGE AND DEALER DID MORE PROGRAMING. NOW IN OCTOBER 2020 REDUCED PROPULSION ERROR CAME BACK AND HYBRID BATTERY IS BAD. WARRANTY RAN OUT IN MAY 2020 AND GM REFUSING TO ACKNOWLEDGE 2018 DATE OF DEFECTIVE BATTERY.
