THE CAR WILL GO BACKWARDS WHILE IN PARK, SPECIALLY WHEN THE BATTERY IS DEPLETED. LATE AT NIGHT I HAD PARKED THE CAR IN THE MIDDLE OF THE STREET GOT OUT AND WAS GOING TO MOVE A TRASH CAN OUT OF THE WAY WHEN THE CAR STARTED ROLLING BACKWARDS. I TRIED TO STOP IT BUT COULD NOT SO I HAD TO JUMP IN AND PUT ON THE BRAKES JUST IN TIME BEFORE IT HIT THE NEIGHBORS CAR. I GOT A BRUISE ON MY KNEE TRYING TO GET IN TO THE CAR. I WAS ABLE TO REPEAT THE PROBLEM AND VIDEO TAPE IT AS PROOF. GM ENGINEERING HAD SOMEONE COME OUT FROM RAYTHEON AND CHECK OUT THE CAR AND HE ALONG WITH THE MECHANIC AT MOSS BROTHERS CHEVY CONFIRMED THE PROBLEM. THEY SAID THEY COULD NOT REPAIR THE PROBLEM, AND THEY WANTED THE CAR BACK AT GM TO RUN FURTHER TESTS ON IT. THEY OFFERED TO REPLACE THE CAR BUT I WAS NOT SATISFIED WITH THE PRICE DIFFERENCE I HAD TO PAY FOR THE REPLACEMENT. THEY HAD TO DELIVER THE CAR ON A TOW TRUCK BECAUSE IT WAS DEEMED TOO DANGEROUS TO DRIVE. THEY TOLD ME THEY WILL NOT REPAIR IT UNDER WARRANTY THE SERVICE MANAGER SAID HE COULD NOT TOUCH IT AT GM ORDER. I AM STILL TRYING TO FIGURE OUT A WAY TO REPLACE THE CAR BECAUSE IT IS UNPREDICTABLE HOW THE PARK AND REVERSE GEARS WILL ACT I HAVE MANY EXAMPLES OF THE PROBLEM ON YOUTUBE AND ON ONE OCCASION THE CAR WOULD NOT GO BACKWARDS IN REVERES AND AFTER A FEW MINUTES IT SUDDENLY JERKED BACKWARDS AT HIGH SPEED SCARING ME AND MY FAMILY. HERE IS THE LINK I PROVIDED TO GM BEFORE THEY TOOK THE CAR IN. HTTPS://WWW.YOUTUBE.COM/PLAYLIST?LIST=PL7ETUGMNBO_7JQP6QEVYDSKWI7OOQF5_D I DON'T WANT SOMEONE TO DIE LIKE THE STAR TREK ACTOR WHO GOT PINED BY HIS CAR. ALL THIS HAPPENED A FEW DAYS AFTER I HAD PURCHASED THE CARD. THE DEALERSHIP HELD MY CAR FOR 30 DAYS BEFORE THEY RETURNED IT TO ME. THEY DID GIVE ME A LOANER FOR THE 30 DAYS.

WHILE SLOWING DOWN APPROACHING A RED LIGHT WITH THE GEAR IN L (REGENERATIVE BRAKING), THE CAR WAS IN ELECTRIC MODE AND TRAVELING AT A LOW SPEED (UNDER 10MPH AND LIKELY LESS THAN 5MPH) WHEN THE PASSENGER SIDE FRONT TIRE WENT INTO A LARGE BUT SHALLOW POT HOLE AT WHICH TIME THE CAR FELT LIKE IT ACCELERATED (AT THE VERY LEAST DECELERATION ENDED). MY FOOT WAS ALREADY ON THE BRAKE PEDAL (NOT SURE IF I WAS PRESSING IT); HOWEVER, I IMMEDIATELY MASHED THE BRAKE PEDAL DOWN AS FAR AS IT WOULD GO. AT FIRST THIS DID NOT SEEM TO HAVE ANY EFFECT. AFTER A MOMENT, THOUGH, IT FINALLY KICKED IN AND THE CAR STOPPED IMMEDIATELY. I DO NOT BELIEVE I HIT THE CAR IN FRONT OF ME (WHICH WAS COMPLETELY STOPPED). HOWEVER, THAT DRIVER WASN'T SURE IF I DID AND ASKED FOR MY INFORMATION (THERE WAS NO PAINT TRANSFER OR ANY MARKS ON MY CAR--THERE WAS A MARK ON THE OTHER VEHICLE WHICH I BELIEVE WAS ALREADY THERE AND THE OTHER DRIVER WASN'T SURE AND WANTED TO TALK TO HER HUSBAND ABOUT IT). NOTE IN THE LATER SECTION THAT ASKS "WAS THERE A CRASH?" I AM MARKING NO AS I DO NOT BELIEVE THERE WAS A COLLISION NOR IS THERE ANY PHYSICAL EVIDENCE ON MY CAR OF A COLLISION. HOWEVER, THE OTHER DRIVER MAY DISPUTE THAT.

THIS HAPPENED TWICE, SEEMINGLY RANDOMLY, WHEN THE VEHICLE WAS STATIONARY IN A PARKING LOT AND TURNED OFF.

BUT SINCE I SAW THAT I WAS NOT THE ONLY ONE WHO HAD HAD THIS PROBLEM, I THOUGHT IT SHOULD BE REPORTED.

VEHICLE BRAKES FAIL TO FULLY ENGAGE INTERMITTENTLY. WHEN SLOWING DOWN ON MULTIPLE SEPARATE OCCASIONS, THE BRAKES WORK INITIALLY, THEN, THE CAR FEELS LIKE IT'S SLIDING ON ICE (DRY SUMMER ROADS) THEN THE BRAKES ENGAGE AGAIN. THE BRAKE PEDDLE GENERALLY FEELS NORMAL AT FIRST, THEN GOES SOFT AND SINKS. I'VE TAKEN THE VEHICLE TO THE DEALERSHIP ON MULTIPLE OCCASIONS WHO'VE STATED THERE'S NOTHING THEY CAN DO. THIS IS A SERIOUS SAFETY CONCERN TO JUST SEND SOMEONE ON THEIR WAY WITH. I'VE ALSO BEEN WORKING WITH GENERAL MOTORS. WHILE WORKING WITH GM, THEY RECOMMENDED I TAKE THE VEHICLE TO A DIFFERENT DEALERSHIP FOR A SECOND OPINION. THE NEW DEALERSHIP FOUND ERROR CODES OUTLINING THE TRACTION CONTROL MODULE IS MALFUNCTIONING AND ELECTRICAL GROUND ISSUES EXIST.

THEY RETURNED TO THE CAR, UNLOCKED BUT DID NOT REMOTE START, & PLACED THEIR PACKAGES IN THE HATCH BEFORE SITTING IN THE CAR & CLOSING THE DOORS. MY WIFE TRIED TO START THE CAR & GOT THE MESSAGE OTHERS HAVE GOTTEN ABOUT THE KEY FOB NOT BEING RECOGNIZED. THEY TRIED AGAIN TO START THE CAR & GOT THE MESSAGE AGAIN & COULD READ ENOUGH BEFORE IT DISAPPEARED TO PUT THE KEY FOB IN THE CENTER CONSOLE. THEN THE DOORS LOCKED WHILE THE WINDOWS WERE UP & THEY STILL COULDN'T START THE CAR. I HEADED TO THEIR LOCATION, ABOUT 15 MINUTES AWAY, PREPARED TO BREAK THE WINDOW. I WAS ABOUT TO TELL THEM TO CALL 911 WHEN THEY SAID THE CAR WAS FINALLY ABLE TO START & THEY DROVE HOME WITHOUT FURTHER INCIDENT.

THE CAR LITERALLY JUST STOPPED WORKING AS I WAS TURNING ON A BUSY ROAD, SO I WAS STUCK RIGHT IN THE MIDDLE OF THE ROAD WITH CARS NEARLY SMASHING INTO THE BACK OF ME. THE STEERING WHEEL LOCKED UP. THE ACCELERATOR STOPPED WORKING. I COULDN'T TURN IT OFF OR ON- IT WAS KIND ON JUST STUCK IN AN ALTERNATE MODE. THERE WAS AN ORANGE ENGINE SYMBOL THAT WAS LIT UP AND IT KEPT SAYING "SHIFT TO PARK" BUT I WOULD SHIFT AND NOTHING WOULD HAPPEN. I COULDN'T PUT IT IN NEUTRAL SO I COULD PUSH IT TO A SAFER LOCATION. NOTHING. THE TECHNICIAN ON THE PHONE DIDN'T KNOW WHAT WAS WRONG WITH IT, BUT SOMEONE WHO STOPPED TO HELP SAID HE USED TO WORK ON THESE CARS AND SAID IT HAPPENS QUITE OFTEN AND IT THERE WAS ABSOLUTELY NOTHING I COULD HAVE DONE TO FIX IT (I THOUGHT I REMEMBER HIM SAYING SOMETHING ABOUT AN ENGINE SWITCH PROBLEM, BUT I WAS SO FRAZZLED I WASN'T REALLY LISTENING TO HIM) . IF THIS HAD HAPPENED ON A HIGHWAY I COULD HAVE BEEN KILLED. I DON'T KNOW HOW THESE CARS HAVE NO BEEN RECALLED.

2PE23022 · 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.
