NHTSA Complaint #10959822 — 2015 CHEVROLET VOLT

2/24/17 WHILE DRIVING ON A PUBLIC BUSINESS 2 LANE ROAD WITH 30 MILES BATTERY LIFE AND 150 MILES GAS AVAILABLE, THE CAR DRIVING AT APPROXIMATELY 25 MILES PER HOUR ON A VERY SLIGHT DECLINING SLOPE WHEN IT COMPLETELY STOPPED IN THE MIDDLE OF THE "FAST" LANE OF TRAFFIC ON A FOUR LANE ROAD - TWO LANES IN EACH DIRECTION. THE WARNING "PROPULSION POWER REDUCED" AND CHECK ENGINE LIGHT WERE BOTH ON. I WAS ONLY SLIGHTLY ABLE TO CONTROL THE CAR BY FORCEFULLY TURNING RIGHT INTO A DRIVEWAY ACROSS ANOTHER TRAFFIC LANE WHILE ROLLING SLIGHTLY DOWNHILL. I WAS ONLY ABLE TO MAKE IT INTO THE DRIVEWAY BEFORE I STARTED ROLLING BACKWARDS AND I FORCEFULLY HAD TO KEEP MY FOOT ON THE BRAKE SO THE CAR WOULD NOT ROLL. WHEN I TURNED OFF THE ENGINE, THE HAZARDS WENT OFF SO I HAD TO TURN THE ENGINE BACK ON SO THAT THE HAZARD LIGHTS WOULD WORK. THE TOW TRUCK DRIVER WAS ABLE TO LOAD IT ONTO THE STAKE BED AND TOLD ME THAT IT WAS WORKING FINE. NO ERRORS ON DISPLAY. IT SAT OFF FOR ABOUT 5 MINUTES AND HE DROVE IT ONTO THE STAKE BED. THE SIERRA CHEVROLET IN MONROVIA CA HAD THE CAR FOR A WEEK, BUT SAID THAT THE CODES DID NOT SHOW UP WHEN THEY TESTED IT. AND THEY EVEN DROVE THE CAR AROUND TOWN FOR 70 MILES. I EXPLAINED TO THEM THAT THIS WASN'T THE FIRST TIME THAT THE CODE SHOWED UP BUT THE OTHER TWO TIMES, IT SHOWED UP THE CAR LOST POWER, WHILE DRIVING UP A HILL AT ABOUT 35MPH, BUT IMMEDIATELY RESTARTED ITSELF....AND THE CODE DISAPPEARED. I INFORMED THE DEALER THAT A FULL CHARGE FROM MY HOUSE USED TO BE MORE THAN 40 MILE RANGE, NOW IT IS DOWN TO 30 - 35 MILES...NEVER 40. I GOT THE CAR BACK WITH NO WORK DONE. ON THE FREEWAY IT HAD TROUBLE GOING MORE THAN 55 MPH SO OPTED FOR SLOW LANE RATHER THAN THE USUAL CAR POOL LANE AND IMMEDIATELY GOT OFF THE FREEWAY. THIS WAS A VERY STRAIGHT FREEWAY, NO INCLINES. PROBLEM STILL EXISTS, FEEL MANUFACTURER NEEDS TO BE NOTIFIED AS IT JUST STOPPED!
