SWITCHING FROM ELECTRIC TO GAS MOTOR WHILE DRIVING APPROXIMATELY 60 MILES PER HOUR, TOTAL LOSS OF POWER. DASHBOARD INDICATOR SAYS TO PLACE IN PARK. WHEN STATIONARY, UNABLE TO TURN VEHICLE OFF. REPEAT START BUTTON AND SHIFTING, UNABLE TO DISENGAGE ENGINE TO RESET AND RESTART ENGINE. HAD TO TOW VEHICLE. CHEVY TECHNICIAN NECESSARY TO DISENGAGE/TURN OFF VEHICLE. RESTARTED WITH GAS. LOSS OF POWER WHEN VEHICLE SWITCHES FROM ELECTRIC TO GAS HAPPENS OFTEN. GENERAL MOTORS/ CHEVY IS UNABLE TO FIX. VECHICLE ONLY HAS 7500 MILES. HAD A COMPLETE SWAP OF TRANSMISSION WITH ONLY 5 MILES ON THE VEHICLE, THE FIRST TIME THIS HAPPENED. COMPLETE LOSS OF POWER ON HIGHWAY IS A HUGE SAFETY ISSUE. UNRELIABLE VEHICLE BEYOND 40 MILES ON ELECTRIC BATTERY. 4 TIMES IN LESS THAN 2 YEARS COMPLETE LOSS OF POWER. 3 TIMES ON HIGHWAY, ONCE CITY STREET. TOWED TWICE. TWICE I WAS ABLE TO TURN OFF THE VEHICLE AND RESTART WITH THE GAS MOTOR. THE OTHER 2 TIMES I WAS NOT ABLE TO TURN OFF THE VEHICLE AND WAS UNABLE TO REGAIN POWER; HAD TO BE TOWED TO NEAREST DEALERSHIP WHERE THE TECHNICIAN SPECIALIST WAS REQUIRED TO DISENGAGE AND RESTART THE VEHICLE WITH THE GAS MOTOR ( AT THIS POINT THERE WAS NO MORE POWER IN THE BATTERY).

ADAPTIVE CRUISE CONTROL UNAVAILABLE RANDOMLY OCCURS WHILE DRIVING USING ADAPTIVE CRUISE CONTROL. PRESENTS A LARGE DANGER OF HITTING OTHER VEHICLES IF THE ADAPTIVE CRUISE CONTROL IS USED TO COME TO A COMPLETE STOP AS IT WILL RANDOMLY DISENGAGE WHILE COMING TO A STOP. CRUISE CONTROL ONLY WORKS 4/10 TIMES ATTEMPTED AND WAS "FIXED" BY THE DEALER WITH LESS THAN 500 MILES ON THE ODOMETER. HOWEVER THE PROBLEM RECURRED WITHIN A DAY. LOOKED IT UP IN FORUMS AND IT IS NOT AN UNCOMMON PROBLEM. HOLDING FOOT UNDER THE BRAKE PEDAL ALLOWS CRUISE CONTROL TO WORK BUT IS MORE DANGEROUS THAN RANDOMLY CUTTING OFF. NO ONE IN VOLT FORUM HAS GOTTEN A COMPLETE FIX TO DATE. WHEN THEY DO I WILL BE GETTING MINE REPAIRED ARMED WITH THE CORRECT INFORMATION. BUT IT IS DANGEROUS.

LIKE OTHERS, INCLUDING THE INCIDENT IN RANCHO CUCOMONGA, CA ON THE SAME DAY, APRIL 25TH, I WAS DRIVING ON THE HIGHWAY AT HIGH SPEED. I WAS IN THE CARPOOL LANE ON THE 210 FREEWAY. I THINK I ALSO WAS TOLD TO PUT THE CAR IN PARK. I LOST THE ABILITY TO ACCELERATE ON AT A VERY DANGEROUS TIME, WHILE I WAS THE FURTHEST TO THE LEFT IN THE LATE AFTERNOON. MIRACULOUSLY, THERE WAS ONLY 1 CAR QUITE FAR BEHIND ME. SO, AFTER DECELERATION WAS FORCED UPON MY CAR, I BEGAN TO STEER THE CAR TO THE RIGHT THROUGH 5 LANES - ONE OF THE WIDEST PARTS OF THE HIGHWAY AT THAT POINT. HERE IS WHAT I NOW THINK. I HAVE BEEN THROUGH LOSS OF POWER IN MY 2014 VOLT. I HAD ACCIDENTALLY TURNED IT OFF WHILE BEING ON THE HIGHWAY. THEY FIXED THAT DESIGN FLAW IN THIS 2017 MODEL. I HAVE SHARED MY THEORY WITH GM. GM/CHEVY HAS 3-WAY CALLED ME WITH THE "STOLEN VEHICLES DEPT". THEY AGGRESSIVELY DESCRIBE HOW THEY WON'T ISSUE A SLOW-DOWN THROUGH THE ON-STAR UNLESS THEY HAVE A REQUEST THROUGH POLICE, THE POLICE ARE BEHIND, THE LIGHTS BLINK, ETC. BUT, THEY'RE RELUCTANT TO SHARE WHAT HAPPENS NEXT. THEY'VE BEEN RELUCTANT TO SHARE HOW THEY TRACK YOUR VEHICLE THROUGH THE VIN AND GPS TRACKING. THEY'RE RELUCTANT TO SHARE THAT THIS SYSTEM CAN BE HACKED. IT IS EVIDENT THAT MUCH CAN GO WRONG ONCE THE ABILITY TO CONTROL YOUR CAR IS PLACED IN OTHER'S HANDS -- WHO AREN'T IN THE CAR DRIVING IT. THE DEALERSHIP COULD SEE THE CODE OF THE SLOW-DOWN. OF COURSE THEY WERE SURPRISED. THIS WASN'T JUST A "FAILURE". THIS IS A "FEATURE" IN THE CAR...BUT SOMEONE ELSE USED IT WITHOUT OUR PERMISSION. I WANT THE ON-STAR CONTROL DISABLED IN MY CAR!!! IT COULD HAVE KILLED MY DAUGHTER AND ME. IT COULD HAVE KILLED THE OTHERS WHO REPORTED A SIMILAR SITUATION.

MY CAR HAS HAD ELECTRICAL PROBLEMS SINCE ALMOST THE FIRST DAY OF OWNERSHIP. MY CAR HAS HAD CONSTANT ELECTRICAL PROBLEMS. I CONTACTED GM AND EVEN SHOWED THEM A VIDEO THAT SHOWED WHAT MY CAR WAS DOING AS FAR AS NOT TURNING OFF WHEN I PRESSED THE BUTTON TO SHUT THE VEHICLE OFF. I WOULD APPEAR TO SHUT OFF ONLY TO TURN BACK ON REPEATEDLY. GM DID ABSOLUTELY NOTHING TO FIX MY ISSUES EXCEPT RUN IN CIRCLES AND CLAIM THEY COULDN'T/WOULDN'T DO ANYTHING ABOUT IT CAUSE THE DEALER COULDN'T DUPLICATE THE PROBLEM. EVEN THOUGH I HAD VIDEO PROOF OF WHAT MY CAR WAS DOING TO ME. IT ONLY HAPPENED AT RANDOM AND WAS VERY SPORADIC. MY CAR HAS NOW CAUGHT ON FIRE AND BURNED TO ALMOST NOTHING AND I AM OUT A LOT OF MONEY. JUST TAKE A LOOK AT MY SITE WWW.CHEVYVOLTSUCKS.COM TO SAY I AM PISSED AT GM IS AN EXTREME UNDERSTATEMENT. NUMEROUS COMPLAINTS WERE MADE AND ONLY PROVED TO BE A TOTAL WASTE OF TIME AND GIVEN LAME EXCUSES. I ALSO HAD REPEATED PROBLEMS OUT OF THE RIMS BENDING CAUSING REPLACEMENT OF THESE RIMS ON AN EXTENDED CONTRACT I HAD THAT COVERED THE RIMS AND TIRES. I HAVE OWNED NUMEROUS CARS OVER THE PAST 30 YEARS AND HAVE NEVER BENT A RIM IN MY LIFE UNTIL THIS CAR AND IT WAS OVER 4 RIMS BENT IN TOTAL IN LESS THAN A YEAR OF OWNING THIS CAR.

AFTER TOW TRUCK CAME, THE CAR STARTED AGAIN AND I WAS ABLE TO DRIVE TO DEALER FOR REPAIR. DEALER FOUND TWO ERROR CODES IN THE HISTORY P0AC4 AND P0604. ALTHOUGH THE CAR IS WORKING FINE AT THIS MOMENT AND SEEMS LIKE IT WAS JUST SOME SORT OF COMPUTER CRASH, HOWEVER IT WAS VERY DANGEROUS TO LOSE PROPULSION ON THE FREEWAY AND STUCK ON A HEAVY TRAFFIC OFF RAMP.

I WAS TRAVELING AT HIGHWAY SPEEDS (70+) ON THE GAS BACKUP MODE THIS WAS THE FIRST TIME DRIVING AT THESE SPEEDS ON 0 BATTERY AFTER PICKING UP MY CAR FROM THE DEALERSHIP IT HAS BEEN 4 DAYS SINCE THE INCIDENT AND I AM UTTERLY DISAPPOINTED THAT NOBODY FROM GM HAS REACHED OUT TO ME REGARDING THIS INCIDENT.

PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module

Opened Nov 29, 2023 · Closed Mar 3, 2025

Status: closed (inferred from source dates) · Electrical System; Electrical System:propulsion System; Electrical System:propulsion System:traction Battery:management System/energy Control Module (bms/becm)

On November 29, 2023, the Office of Defects Investigations (ODI) opened PE23022 to investigate allegations of a loss of motive power, including a stall, reduced power state, and/or a no start condition due to the Battery Energy Control Module (BECM) in model year (MY) 2016-2019 Chevrolet Volt passenger car vehicles manufactured by General Motors (GM). The BECM is located within the high voltage electric vehicle (EV) battery pack and monitors the temperature, current, and voltage of the high voltage battery cell groups. GM stated that the root cause was identified as an internal failure leading to a loss of communication within the BECM and does not pose a risk to motor vehicle safety. GM further stated that the failure cannot result in a complete stall, only a reduced power mode, no start condition, or a no charge condition. GM additionally stated that if these conditions occur, the driver will be warned via a Malfunction Indicator Lamp (MIL) and/or a reduced-propulsion message in the Driver Information Center (DIC). Data received and analyzed by ODI from all sources indicates that nearly all related BECM failures caused conditions aligning with GM’s predicted outcomes. Despite the large number of warranty claims, nearly all failures were not safety-related, i.e., not a stall or reduced power mode. ODI isaware of a single minor crash and no injuries or deaths. In March 2024, GM issued Special Coverage N232432680, which was mailed to consumers, addressing BECM failures in certain MY 2016-2018 Chevrolet Volt vehicles. This special coverage provides an extension of the warranty coverage for the BECM from 8 years / 100,000 miles to 15 years / 150,000 miles for all 2016-2018 Chevrolet Volts. Additionally, GM stated that replacement components are sourced from a different supplier and not susceptible to the failure. In view of the Special Coverage issued by GM, the existing warranty coverage already in place, and the low number of safety-related occurrences, ODI is closing this Preliminary Evaluation (PE). 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 future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
