I WAS DRIVING MY 2013 CHEVROLET VOLT AND I RECEIVED A LOSS OF PROPULSION MESSAGE ON MY DASHBOARD AND IMMEDIATELY FOLLOWED BY A CHECK ENGINE LIGHT. MY CAR SHUT DOWN AND SLOWED DOWN ON THE FREEWAY AS I WAS DRIVING. IT WAS VERY DANGEROUS BECAUSE IT WAS ALSO DARK. I WAS ABLE TO GLIDE TO EXIT THE FREEWAY. MY CAR CAME TO A COMPLETE STOP IN THE EXIT LANE OF THE FREEWAY. I PRESSED THE POWER BUTTON TO TURN OFF THE CAR AND THEN I WAITED ABOUT 30 SECONDS AND I TURNED THE POWER BUTTON BACK ON AND THE CAR CAME ON AS ONLY POWER MODE. I WAS ABLE TO MOVE THE CAR VERY SLOWLY SOMEWHERE MORE SAFE. I CALLED TOW TRUCK AND I TOWED IT TO DEALERSHIP. THE VOLT WAS STILL ABLE TO MOVE SLOWLY UP THE TOW TRUCK AND WHEN I ARRIVED AT THE DEALERSHIP, IT WAS STILL ABLE TO MOVE SLOWLY TO THE ENTRANCE OF THE SERVICE STATION. CHECK ENGINE LIGHT WAS ON, BUT LOSS OF PROPULSION LIGHT WAS GONE. SERVICE ADVISORS TOLD ME THEY WOULD FIX MY CAR AS IT WAS COVERED UNDER THE RECALL EVEN THOUGH MY CAR WAS SALVAGED. THE ESTIMATE WAS $145. LATER ON THEY CALLED ME THAT MY CAR HAD 8 CHECK ENGINE LIGHTS ON AND THAT I NEEDED A TRANSMISSION BECAUSE THEIR WAS A WHINING SOUND AND ALSO LOSS OF PROPULSION STILL ON. I WENT TO GO LOOK AT MY CAR A COUPLE DAYS LATER AFTER I FILLED A COMPLAINT WITH GM HEADQUARTERS BECAUSE THIS SHOULD BE COVERED UNDER THE RECALL. WHEN I WENT TO GO CHECK OUT MY VEHICLE, IT WAS IN A WORSE CONDITION THEN WHEN I DROPPED IT OFF. MY CAR WOULD NOT EVEN TURN ON. WHEN I PUSHED THE POWER BUTTON, IT WOULD SAY ENGINE NOT AVAILABLE AND IT WOULD ALSO SAY LOSS OF PROPULSION AND CHECK ENGINE LIGHT STILL ON. I WAS NOT ABLE TO MOVE MY CAR AND THE BATTERY STILL HAD 8 MILES LEFT. IT WAS WEIRD AS TO WHY MY CAR IS GETTING WORSE WHILE BEING IN THE DEALER. DEALER TOLD ME THEY ARE DONE WITH THE UPDATE AND IN ORDER TO DIAGNOSE THE VEHICLE, I HAVE TO PAY $430 AND MORE THAN LIKELY THOUSANDS OF DOLLAR TO FIX IT.

I HAVE HAD MY CAR FOR 2 YEARS AND HAVE NOT EXPERIENCED ANY ISSUES WITH THE BATTERY OR PROPULSION CONTROL SYSTEM. I GOT A RECALL NOTICE TO FIX "LOSS OF PROPULSION DUE TO LOW CELL VOLTAGE". THE SERVICE TEAM WAS VERY NICE, I SAT IN THEIR WAITING ROOM FOR ABOUT TWO HOURS. THEY SAID IT WAS DONE SO I THEN WENT TO WORK FOR A COUPLE HOURS. WHEN DRIVING HOME I GET TO THE POINT WHERE THE INITIAL ELECTRICAL BATTERY IS DEPLETED AND THEN IT TURNS ON THE GAS GENERATOR. I IMMEDIATELY GET AN ALERT "LOSS OF PROPULSION" AND THE CAR STOPS ACCELERATING AND DRIVES VERY DIFFERENT. LOW ACCELERATION, AC TURNS OFF. I MAKE IT HOME AND THEN THE CHARGING SYSTEM SAYS IT IS NOT WORKING. I TRY TO TURN THE CAR BACK ON AND IT DOESN'T LET ME PUT IT IN GEAR. I CALLED ON STAR AND THEY SCHEDULED A TOW TRUCK TO COME AND HAVE IT TOWED BACK TO THE DEALERSHIP. WILL LET YOU KNOW HOW IT GOES.

WHILE ON THE HIGHWAY AND THE MAIN HIGH VOLTAGE BATTERY IS DEPLETED, I HAVE A SUDDEN REDUCTION IN SPEED AND ZERO ACCELERATION. I GET A DASHBOARD ALERT "PROPULSION POWER REDUCED". "REDUCED" IS AN UNDERSTATEMENT! THE GAS ENGINE TRIES TO KEEP UP WITH SPEED BY RAMPING UP THE RMPS. THE SUDDEN LOSS OF SPEED FORCES OTHER CARS TO AVOID ME AND I CANNOT INCREASE MY SPEED IF NEEDED. I EXPECT I WILL BE REAR ENDED OR LOSE CONTROL WHEN THIS HAPPENS AGAIN. ENGINE REVS EXTREMELY HIGH. I USUALLY PULL OVER AND TURN OFF VEHICLE- SOMETIMES A RESTARTS FIXES IT. I HAVE ALSO WAITED (5 MINS?) WITH THE ENGINE RUNNING AT HIGH RMPS HOPING THE BATTERY WOULD RECOVER, BUT NO. I ALSO FEAR THE GAS ENGINE WILL OVERHEAT. THE CAR CAN NO LONGER DRIVE AT HIGHWAY SPEEDS SAFELY AFTER DEPLETION AND CANNOT ACCELERATE SUFFICIENTLY EVEN IN A 30MPH ZONE. THIS IS A CONTINUING ISSUE AND HAS HAPPENED FOR THE PAST SEVERAL DAYS. THE DEALERSHIP SAYS THE HIGH VOLTAGE BATTERY IS BAD, BUT THE MAIN BATTERY CHARGES AND DRIVES FINE UNTIL IT IS DEPLETED. I NOW DON'T DRIVE FARTHER THAN WHAT THE EV BATTERY CAN ACHIEVE. (ALL OTHER CURRENT RECALL ISSUES, SOFTWARE UPDATES HAVE BEEN ADDRESSED)

2013 CHEVY VOLT STOPPED ACCELERATING AND RECEIVED A LOW PROPULSION WHILE DRIVING ON A STATE ROUTE IN OHIO. OUR SON WAS DRIVING THE VEHICLE AND COULD HAVE BEEN KILLED IF THIS WAS ON A HIGHWAY. THE VOLT WOULD NOT MOVE AND HE HAD TO TRY TO GLIDE OFF THE ROAD SINCE IT HAD NO POWER. HE PUSHED THE CAR OFF THE ROAD SO IT WOULD NOT BE HIT. IF THIS SITUATION WOULD HAVE OCCURRED WHILE DRIVING ON THE HIGHWAY, OUR SON COULD HAVE BEEN KILLED. THIS PROBLEM HAS OCCURRED TO OTHER VOLT OWNERS IF YOU LOOK THIS ISSUE UP ON THE INTERNET. WHY HASN'T GM FIXED THIS ISSUE SO PEOPLE ARE SAFE WHEN DRIVING THIS VEHICLE? WE BROUGHT OUR VOLT INTO THE SERVICE DEPARTMENT, THIS CAR IS NOW GOING ON 3 WEEKS AND WE STILL DO NOT HAVE OUR CAR BACK. THEY FIRST SAID IT WAS A SHORT IN THE ELECTRICAL MODULE, AND REPLACED PARTS. NOW THEY ARE STATING THAT IT DID NOT WORK AND IT IS THE TRANSMISSION. I AM NOT SURE THEY KNOW WHAT IS REALLY WRONG WITH THIS VOLT. THEY ARE NOW ASKING US TO PAY $3661 TO HAVE THIS TRANSMISSION REPLACE AND GM WILL PAY 2000 OR IT WOULD BE 5661. THIS CAR IS NOT EVEN WORTH THAT MUCH AT THIS POINT HAS 83000 MILES ON IT AND THE TRANSMISSION SHOULD HAVE NEVER WENT OUT. GM TRIED TO SAY IT WAS THE SHORT, NOW THEY ARE SAYING IT WAS NOT A SHORT. I DO NOT CARE WHAT IT IS I JUST WANT A SAFE CAR FOR MY SON TO DRIVE. IT SEEMS LIKE THEY ARE BACK PEDALING TO TRY TO NOT PAY FOR SOMETHING THAT THEY (GM) SHOULD PAY FOR. ESPECIALLY SINCE THIS ISSUE IS NOT A NEW ISSUE FOR THE CHEVY VOLT. GM NEEDS TO STAND BY THEIR PRODUCTS AND FIX THIS VEHICLE.

ON SEPT. 5TH 2018 I HIT THE CENTER ISLAND WHILE TURNING ON THE CITY STREET AT ABOUT 15MPH. THE IMPACT WAS SO SLIGHT THAT THE AIR BAGS DIDN'T EVEN DEPLOY. I WAS ABLE TO GET IT TO THE DEALERS ON IT'S OWN POWER. MY INSURANCE COMPANY SENT THEIR APPRAISER ,JEREMY , TO INSPECT THE DAMAGE. I HAD TO GET SOME ITEMS OUT OF MY CAR BEFORE THAT. THE MECHANIC HAD THE CAR ON THE RACK SO HE COULD SHOW ME. THE ONLY DAMAGE I READILY NOTICED WAS THE RADIATORS WERE CRUSHED, A 2 1/2" SQUARE FRAME CROSS MEMBER HAD A 1 1/2" DENT WHERE IT HAD IMPACTED THE ISLAND , AND SOME PANELS- NOTICEABLY THE FRONT UNDERSIDE AND DRIVER SIDE FRONT WHEEL WELL WERE DAMAGED. LATER JEREMY CALLED ME AND TOLD ME THE CAR WAS A TOTAL LOSS.HE SAID THE ENTIRE FRAME WAS BENT OUT OF SHAPE. I COULDN'T BELIEVE IT. IN HIS REPORT HE ITEMIZED THE PARTS BUT ABOUT THE PROPULSION SYSTEM HE WROTE, CONDITIONS EXIST THAT THE ELECTRICAL MOTORS COULD START UP THE GAS ENGINE AND FLOOD THE PASSENGER COMPARTMENT WITH CO. WELL IF THAT'S THE CASE, WHY DON'T THEY SIMPLY REPLACE THE COMPONENTS THAT WOULD LEAD TO THAT CONDITION OR IF IT WAS INHERENT IN THE CAR, WHY DOESN'T THE DOT DECLARE THE CAR A ROAD HAZZARD AND RECALL ALL VEHICLES? LN CONSUMER REPORTS THEY DECLARED THE VOLT SCORED 5 OUT OF A POSSIBLE 5 RATING ON COLLISION SURVIVAL. WHAT? THE CAR RUNNING AT 15 MPH GETTING TOTALLED BY HITTING A BUMP IS A 5? I THINK MR. JEREMY IS PADDING ALL HIS ESTIMATES AND SHOULD HAVE AN INDEPENDENT APPRAISER REVIEW THE CAR. EITHER HE IS LYING OR THE CAR IS ACTUALLY A LEMON. I WOULD LIKE YOUR ADVICE ON WHAT LEGAL COURSE I SHOULD TAKE.

Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
PE19013 · Passenger Sensing System
Opened Sep 17, 2019 · Closed Jul 2, 2021
Status: closed (inferred from source dates) · Air Bags:sensor:occupant Classification:front Passenger
In September 2019, the Office of Defects Investigation (ODI) opened PE19-013 to assess the potential safety related effects of a malfunction of the Passenger Sensing System (PSS) in 2012-2013 Model Year (MY) Chevrolet Volt vehicles. Consumers reported that due to a malfunction of the PSS, the air bag system malfunction indicator light (MIL) was activated. Many of the complaints noted the malfunction occurred after the warranty period expired and mentioned high repair costs as a major deterrent to the repair of the vehicle.The PSS sensor mat is embedded in the front passenger seat cushion and is intended to detect child seats and small statured occupants who could be harmed by deployment of the frontal passenger air bag. The PSS may develop a malfunction due to bunching of the sensor mat in the seat trench. The bunching of the sensor mat could cause the mat to repeatedly fold in the same location. Over time, the repeated folding can cause an increased resistance in the sensor mat. An increased resistance in the PSS sensor mat is detected as a fault in the air bag system diagnostic. If this fault is detected, a diagnostic trouble code will be stored in the air bag control unit and the air bag MIL will illuminate.Further, if the fault is detected, the passenger frontal and knee air bags will be suppressed in a crash of sufficient severity to warrant a commanded deployment regardless of the nature of size of the occupant of the front passenger seat.The report counts shown above include only those reports that specifically address the issue covered by this investigation, failure of the PSS sensor mat. Reports alleging only that the air bag light is on with no cause stated, or where a different cause was otherwise identified, were excluded as the air bag light could be illuminated for system faults other than a PSS malfunction.The subject vehicles have been in service for approximately ten (10) years. An analysis of General Motors (GM) warranty data for the subject vehicles, including a comparison with other agency and manufacturer data pertaining to similar occupant detection system failure investigations, indicates the subject vehicles experience a comparatively low complaint rate for this issue given the number of years the vehicles have been in service.GM has instituted a cost reduction program for the repair/replacement of the PSS in the subject vehicles. Based on this cost reduction program as well as:1) a comparatively low warranty rate; 2) no reported injuries, deaths or asymmetric deployments; and 3) the age of the vehicles; ODI is closing this Preliminary Evaluation. The closing of this investigation does not constitute a finding by NHTSA that a safety related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers in a separate attachment.
