WHILE DRIVING TO THE DEALERSHIP TO GET MY CAR SERVICED FOR NEARLY STALLING AT A STOP LIGHT MY CAR ENGINE KEPT TURNING ON AND OFF AND REVVING UP AND DOWN RANDOMLY. I WAS IN ELECTRIC MODE AND THE ENGINE SHOULD NOT HAVE BEEN COMING ON. THE CAR'S SPEED RANDOMLY FLUCTUATED AS THE ENGINE RANDOMLY REVVED UP AND DOWN. I PULLED IN TO A GROCERY STORE PARKING LOT WHERE MY CAR DIED. BEFORE DYING THE GAS RANGE INDICATOR CHANGED FROM 87 MILES TO 'LOW FUEL'. I CALLED THE DEALERSHIP TO HAVE MY CAR TOWED. AFTER 16 DAYS I GOT MY CAR BACK. THE DEALERSHIP REPLACED THE ENGINE CONTROL MODULE TWICE. THE FIRST REPLACEMENT FAILED WITHIN A 1 MILE TEST DRIVE BY THE MECHANIC.

VEHICLE'S LANE DEPARTURE FUNCTION AND CALIBRATION WAS REPROGRAMMED AFTER A RECALL SERVICE AND NOT FUNCTION DOES NOT WORK. FUNCTION WAS NOT ONLY A PREMIUM CHARGE OPTION, BUT ORIGINALLY WOULD MONITOR THE LANE LINES AND ADJUST THE ELECTRONIC STEERING SYSTEM TO KEEP THE VEHICLE WELL WITHIN THE ROAD LANES' PAINTED LINES. NOW, THE VEHICLE WILL (MORE TIMES THAN NOT) COMPLETELY CROSS THE TIRES WELL OVER THE PAINTED LINE, TRAVELING SEVERAL TENS OF YARDS BEFORE ONLY SLIGHTLY CORRECTING ITS DIRECTION BACK TOWARDS THE LANE. IN A BEST CASE SCENARIO, VEHICLE SYSTEM WILL BEGIN CORRECTING ITSELF APPROXIMATELY JUST AS THE FRONT TIRE MAKES CONTACT WITH THE LANE BOUNDARY LINES. THIS HAS BEEN OBSERVED IN LANES OF VARYING WIDTH AND CONFIRMED BY THE SERVICING DEALERSHIP. FURTHER, SYSTEM IS INCONSISTENT IN ITS DETERMINATION AND "CORRECTION" LANE BOUNDARIES, SOMETIMES CROSSING THE LEFT LANE LINE ENTIRELY THEN BARELY TOUCHING THE RIDE SIDE LANE, OR VICE VERSA. SYSTEM HAS ALSO BEEN APPARENTLY LESS SENSITIVE IN READING THE LINES AS THE INSTRUMENT PANEL INDICATOR WILL NOT LIGHT UP INDICATING THAT IT RECOGNIZES LANES, EVEN THOUGH LANES ARE CLEARLY AND BRIGHTLY PAINTED AND ILLUMINATED BY EITHER HEADLIGHTS, STREET LIGHTS OR SUNLIGHT. AS THIS VEHICLE IS A COMPLETE DRIVE-BY-WIRE SYSTEM (BRAKES, STEERING, AND THROTTLE HAVE NO MECHANICAL CONNECTION TO DRIVER'S INPUTS), I HAVE SERIOUS CONCERNS WITH REGARDS TO THE SENSORS CAPABILITIES IN ACCIDENT AVOIDANCE AND FEEL THAT IN AN EMERGENCY SITUATION, THE SYSTEM WILL FAIL TO OPERATE AS PROMOTED AND PROMISED BY THE MANUFACTURE. THIS WOULD BE ACCEPTABLE IF THIS PERFORMANCE WAS SIMILAR OR CONSISTENT TO PERFORMANCE FROM INITIAL OPERATION, HOWEVER, THE OEM HAS EFFECTIVELY AND DRAMATICALLY CHANGING THE VEHICLE'S DRIVING DYNAMIC AND SAFETY FUNCTION THAT I (AND ANY REASONABLE DRIVER) HAVE BECOME COMFORTABLE WITH AS A DRIVER, WITHOUT MY CONSENT.

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.

OTHER THINGS THAT DON'T WORK INCLUDE BLUETOOTH, RADIO, ON STAR, CONTROLS FOR THE VEHICLE SETUP AND CHARGING PARAMETERS, AIR CONDITIONING, ENERGY USAGE DISPLAY, AND SO ON. AFTER SEVERAL SERVICE VISITS AND CALLS TO GM, THEY DETERMINED THAT IF YOU LEAVE A PHONE PLUGGED INTO THE USB CORD FOR THE AUDIO SYSTEM, AND POWER THE CAR OFF WITHOUT FIRST UNPLUGGING THE PHONE FROM THE CHARGER AND EVEN THE CHARGER CORD FROM THE USB PORT (WITH NO PHONE PLUGGED IN) OR ELSE THE NEXT TIME YOU START THE CAR THE SCREEN AND FUNCTIONS ON IT WILL BE INOPERABLE UNTIL THE CAR IS POWERED OFF FOR SEVERAL MINUTES. WHETHER OR NOT I UNPLUG MY PHONE WHEN I TURN OFF THE CAR SHOULD PREVENT THE BACKUP CAMERA FROM FUNCTIONING NOR THE DETAILS ABOUT ELECTRIC CAR CHARGE USAGE. GM HAS TOLD ME THERE IS NOTHING MORE THEY CAN DO, THAT'S JUST HOW IT WORKS.

WHILE DRIVING THE VEHICLE ON A FREEWAY A LIGHT CAME ON STATING ALL SYSTEMS WOULD SHUT DOWN AND ALL SYSTEMS DID SHUT DOWN IMMEDIATELY. THERE WAS HARDLY TIME ENOUGH TO PULL OVER TO THE SIDE OF THE ROAD. EVEN THE ONSTAR SYSTEM WAS INOPERABLE TO CALL FOR ASSISTANCE. THE DOOR FOB WOULD NOT WORK TO OPEN THE CAR DOORS. THE CAR WAS TOWED TO THE NEAREST DEALERSHIP. THE TOW COMPANY WAS UNABLE TO PLACE THE CAR IN NEUTRAL SO SKATES WERE USED TO PLACE THE VEHICLE ON A FLATBED TOW TRUCK. THE CHEVROLET DEALERSHIP, SINGH, RIVERSIDE, CA THAT RECEIVED THE TOW VEHICLE STATED THE PROBLEM WAS DUE TO 3 DEFECTIVE FUSES THAT HAD SOMETHING TO DO WITH THE BATTERY SYSTEM OF THE VEHICLE. I WAS TOLD THAT THE FUSES WERE PRODUCED OVERSEAS AND THAT THERE WERE NO PARTS AVAILABLE FOR THE CAR AND NO ESTIMATED DATE WHEN THE PARTS WOULD BECOME AVAILABLE. THE SERVICE REPRESENTATIVE AT THE DEALERSHIP INFORMED ME THAT GMC HAD SENT OUT A FLYER RELATING TO THIS PROBLEM AND THAT IT WAS A KNOWN PROBLEM. AFTER 3 WEEKS I WAS TOLD THE CAR WAS REPAIRED AND I PICKED IT UP. THREE DAYS AFTER PICKING UP THE CAR I HAD THE SAME PROBLEM. THE CAR WAS TOWED BACK TO THE SAME DEALERSHIP. A GMC FIELD TECHNICIAN WAS DISPATCHED TO THE DEALERSHIP TO RUN DIAGNOSTICS ON THE CAR. GMC IS IN THE PROCESS OF RE-PURCHASING THE VEHICLE FROM ME UNDER THE CALIFORNIA LEMON LAW. THE CAR HAS BEEN AT THE DEALERSHIP FOR REPAIR OF THIS PROBLEM FOR 7 WEEKS.

2017 CHEVROLET VOLT EXTREME ENGINE HAZARD: ON 22-MAR-2016 I PURCHASED A 2017 CHEVROLET VOLT PREMIER, ALL SAFETY OPTIONS. DRIVING ON FREEWAY AT 65 MPH, STRAIGHT DRIVING, RELATIVELY LIGHT TRAFFIC, THE ENGINE LIGHT CAME ON YELLOW AND STEADY (EMISSIONS SYSTEM SERVICE WARNING) BUT THE CAR UNCONTROLLABLY DECELERATED. THE FREEWAY HAD NO SHOULDER DUE TO CONSTRUCTION. THE CAR SMELLED OF BURNING ELECTRICAL INSULATION CONFIRMED BY THE TOW TRUCK DRIVER. THE CAR, WITH LESS THAN 150 TOTAL MILES, IN CLEAR WEATHER, AT TWILIGHT, 76 DEGREES, CALIFORNIA AT SEA LEVEL, STRAIGHTAWAY, HAD A SUDDEN AND NEAR TOTAL LOSS OF ALL PROPULSION. THIS CAUSED A LACK OF CONTROL (OBVIOUSLY) IN THE FORWARD DIRECTION, CAUSING AN EXTREME HAZARD ON THE FREEWAY. I AM AN EXPERIENCED DRIVER: MAKE NO MISTAKE, THIS WAS A SERIOUS MANUFACTURE'S ERROR. I CHECKED, NO PARKING BRAKE, THE CAR WAS IN DRIVE GEAR, I HAD BOTH ELECTRIC RANGE AND OVER 7/8 TANK OF GAS SHOWING A GAS RANGE OF 360 MILES - AND I HAD JUST DRIVEN 60 MILES. THERE WAS NO BRAKE SMELL, AS I DID NOT NEED TO APPLY THE BRAKE BECAUSE THE ENGINE GAVE NO PROPULSION. MY HAND WAS OFF THE REGEN SWITCH. THE CAR HAD A MAJOR MALFUNCTION CAUSING AN EXTREME HAZARD, AND BASED ON THE SMELL, POSSIBLE FIRE HAZARD.

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.
