2012 Chevrolet Volt Fuel System Problems

2012 Chevy Volt, has been stalling out on the highway since it was brand new, every 6 months. It has been to the Chevrolet dealer many times and they just reset it and move on. In every case the car works for a short time, 6 to 8 months max and dies out again. They have updated the software many times, but nothing has changed it. It keeps stalling out on the interstate with high speed traffic, a severe hazard. Chevy dealerships have never been able to get to the core of the issue. The last time it died, the dealer said they did not know what else to do and told me to call GM. I have every receipt of this happening. The last time this happened is today, 9/29/2021 and has happened 3 times in the last month now. My wife and kids life was at risk several times with this car. It is an extreme safety hazard.

[XXX] 2012 CHEVROLET VOLT THE VEHICLE HAS BEEN STOPPING AT THE END OF A BATTERY CHARGE WHEN IT'S SUPPOSED TO SWITCH TO THE GASOLINE MOTOR. THE HYBRID BATTERY MANAGEMENT HAS A LOSS OF PROPULSION MESSAGE CAUSED BY THE BATTERY VOLTAGE IN VARIOUS CELLS NOT BEING BALANCED. THERE WAS A RECALL AND THE ONLY CHANGE IS WHEN THE CAR STOPS IT IS ABLE TO LIMP OFF THE ROAD INSTEAD OF COASTING IN NEUTRAL. THE ORIGINAL PROBLEM WAS NOT FIXED Y THE RECALL. ALSO THE RECALL WAS APPLIED TO THE 2013 AND NEWER AND NOT TO THIS VIN. THE NEWLY RECALLED SETTINGS ARE NO BETTER THAN THE ORIGINAL ISSUE AND THE SAME CONDITION IN SOFTWARE IS CAUSING A POWERTRAIN FAILURE WHILE DRIVING. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

COMPLETE LOSS OF PROPULSION WHILE DRIVING AT HIGHWAY SPEED IMMEDIATELY AFTER TRANSITION FROM BATTERY TO FUEL. ABLE TO COAST OFF OF INTERSTATE AND COME TO A STOP ON A BUSY FRONTAGE ROAD, NOT ABLE TO ACCELERATE FURTHER TO MOVE OUT OF TRAFFIC.

MY 2012 CHEVROLET VOLT SHUTDOWN WHILE DRIVING WITH A FULL TANK OF GAS WHEN THE ELECTRIC BATTERY REACHED ZERO RANGE. THE CAR WENT INTO NEUTRAL ON THE FREEWAY AT 65MPH AND WOULD NOT MOVE UNDER ITS OWN POWER. THE CAR WOULD NOT JUMP START OR CHARGE. THE HPCM2 HAS DISABLED CHARGING AND CAUSED A CHECK ENGINE LIGHT WITH ALL 4 BATTERIES IN LOW VOLTAGE LOCK OUT. THIS IS THE SAME PROBLEM AS ANOTHER RECALL WHICH GM WILL NOT PERFORM BECAUSE THE VIN WAS NOT INCLUDED. NHTSA CAMPAIGN NUMBER: 18V397000 I HAVE A UNSAFE CAR THAT IS NOW LOCKED OUT UNTIL THE RECALL IS APPLIED BUT THE FACTORY WILL NOT APPLY THE RECALL.

VEHICLE HAS BEEN TO THREE DIFFERENT GM DEALERSHIPS ALL WITH A FAILURE OF ACCELERATION AND THE MESSAGE THAT APPEARS ON THE DASH OF "PROPULSION POWER IS REDUCED." TODAY IT ALMOST CAUSES AN ACCIDENT AS MY DAUGHTER PULLED INTO TRAFFIC TO MAKE A LEFT TURN WHEN THE VEHICLE DID NOT ACCELERATE CAUSING THE OTHER DRIVER TO TAKE EVASIVE ACTION TO AVOID A TRAFFIC CRASH. DO PEOPLE NEED TO DIE BEFORE THIS ADDRESSED BY GENERAL MOTORS?

WARNING MESSAGE SAYING I HAD LIMITED PROPULSION CAME ON WHEN DRIVING NORMALLY IN NEIGHBORHOOD.. NO WARNING LIGHT CAME ON WITH IT. I COULD NO LONGER ACCELERATE. I PULLED OVER AND TURNED OFF THE CAR. TURNED IT BACK ON AND MESSAGE AND PROBLEM WERE GONE. THIS IS SECOND EVENT LIKE THIS.

TAKATA RECALL: THIS HAS HAPPENED SEVERAL TIMES OVER THE LAST 2-3 YEARS. I BELIEVE IT HAPPENS MOSTLY AFTER THE CAR HAS BEEN SITTING FOR AN HOUR AND AFTER THE ENGINE IS ON GAS ONLY. I WILL DRIVE A FEW MINUTES AND THE WARNING LIGHT COMES ON THE "PROPULSION POWER IS REDUCED." I HAVE TO STOP AND PULL OVER. THE CAR WILL NOT ACCELERATE. IT HAS HAPPENED IN ALL TEMPS AND ALL TIMES OF DAY. THE ENGINE RUNS ROUGH AND MY GAS MILEAGE PLUMMETS. THE LAST 2 TIMES THE BATTERY HAS RECHARGED WHILE I DROVE IT WITH ADDITIONAL BATTERY ONLY TIME OF UP TO 5 MILES. IT HAS HAPPENED AT LEAST 6 TIMES OVER THE LAST 3 YEARS AND THE LAST TIME I WAS ALMOST RUN OVER BY A LARGE DUMP TRUCK. IT HAS HAPPENED 3 TIMES MERGING ONTO A BUSY HIGHWAY. I HAVE BROUGHT IT TO THE DEALER 4 TIMES FOR THIS PROBLEM AND THEY CANNOT REPRODUCE IT SO THEY SAY THEY CAN'T FIX IT. THE LAST CLOSE CALL SCARED ME SUFFICIENTLY THAT I HAVE ASKED THE DEALER SERVICE REPAIR TO NOTIFY GM AND THEY SAID THERE IS NOTHING THEY CAN DO WITHOUT A CODE. I DON'T HAVE THE DOCUMENTS FROM THE LAST VISIT TO SERVICE AS IT IS STILL IN THE SHOP.

SERVICE HIGH VOLTAGE CHARGING SYSTEM CHECKED RESERVOIR AND IT IS BELOW COLD LEVEL MARK SYSTEM WILL NOT CHARGE NOW

GM SENT ME THE FOLLOWING LETTER DATED SEPT. 2016: "THIS LETTER IS INTENDED TO MAKE YOU AWARE THAT SOME 2012 MODEL YEAR CHEVROLET VOLT VEHICLES MAY HAVE A CONDITION WHERE THE ACCELERATOR PEDAL CAN BREAK AT THE STALK JUST BELOW THE HOUSING DUE TO THE DRIVER ENTERING OR EXITING THE VEHICLE WITH THEIR FOOT RESTING ON THE ACCELERATOR PEDAL. IF THE PEDAL BREAKS, IT WOULD NOT BE POSSIBLE TO OPERATE THE ACCELERATOR ONCE THE STALK HAS BROKEN OFF. THE VEHICLE WOULD RETURN TO IDLE REGARDLESS OF TRANSMISSION GEAR POSITION. DO NOT TAKE YOUR VEHICLE TO YOUR CHEVROLET DEALER AS A RESULT OF THIS LETTER UNLESS YOU BELIEVE THAT YOUR VEHICLE HAS THE CONDITION DESCRIBED ABOVE...IF THIS CONDITION OCCURS ON YOUR 2012 VOLT WITHIN 10 YEARS OF THE DATE YOUR VEHICLE ORIGINALLY PLACED IN SERVICE OR 120K MILES, WHICHEVER OCCURS FIRST, THE CONDITION WILL BE REPAIRED FOR YOU AT NO CHARGE." IN OTHER WORDS, GM WILL NOT RECALL THE VEHICLE AND REPAIR THE PEDAL IN ADVANCE. IF IT BREAKS, THEY'LL FIX IT, BUT THE CAR WILL BE INOPERABLE SO IT WILL HAVE TO BE TOWED TO A DEALER. THIS IS NOT ONLY DANGEROUS, IT COULD HAPPEN IN A REMOTE LOCATION. I SPOKE WITH A VOLT REPRESENTATIVE TODAY WHO CONFIRMED THAT GM WILL NOT RECALL THE CAR AND WILL ONLY MAKE THE REPAIR IF NEEDED, AND ONLY WITHIN 10 YEARS OR 120K MILES. THIS IS A SERIOUS PROBLEM AND GM SHOULD BE REQUIRED TO ISSUE A MANDATORY RECALL AND MAKE THE REPAIR QUICKLY AND FREE OF CHARGE. THE LETTER IS SIGNED BY TERRY INCH, EXECUTIVE DIRECTOR, GM GLOBAL CONNECTED CUSTOMER EXPERIENCE. THE LETTER PROVIDED A CUSTOMER SERVICE NUMBER OF 1-800-222-1020.

WHEN FILLING THE GAS TANK: BACK PRESSURE IS SENSED BY GAS STATION PUMP AND STOPS THE FLOW OF GAS AFTER A QUICK MOMENT. CONTINUING THESE SHORT BURSTS CAN TAKE A LONG WHILE. IF TRYING TO FUEL SLOWLY BELOW THE THRESHOLD OF THE BACK PRESSURE BEING SENSED BY THE PUMP, IT COULD RESULT IN GASOLINE FLOWING AND SQUIRTING OUT OF THE GAS TANK OPENING, ONTO: THE CAR, TIRE, BRAKES, UNDERSIDE OF CAR & THE ATTENDANT FILING THE GAS TANK.

THE POWER (PROPULSION) SYSTEM HAS DISAPPEARED FROM SCREEN WHILE DRIVING SWITCHING TO FUEL ONLY. SCREEN GOES BLANK AND ALL ELECTRIC MILES DISAPPEAR. NOTE THIS HAS HAPPENED FOUR TIMES IN THE LAST FEW MONTHS, SENDING SEVERAL ERROR CODES EACH TIME AND THE DEALER KEEPS IT FOR A WEEK OR MORE TO RESET ENGINE AND BATTERY ICON. CORPORATE OFFICE TECH'S HAVING PROBLEMS WITH ANSWERS, TOOK MY CONTROLS AND BATTERY BACK FOR TESTING AND REPLACED WITH NEW ONES. STILL HAVING THE SAME PROBLEM. *TR
