THIS IS AN UPDATE TO MY ORIGINAL COMPLAINT #:11299056 FOR UN-COMMANDED ACCELERATION ON 1/13/2020. THE CHEVY DEALERSHIP WORKED WITH GM CORPORATE ENGINEERS AND WERE UNABLE TO DUPLICATE THE PROBLEM AFTER SEVERAL DAYS. THE RETURNED THE CAR AND BLAMED IT ON THE FLOOR MAT. THIS IS NOT LIKELY SINCE THE MAT IS A OEM HEAVY RUBBER MAT AND THE ACCELERATOR PEDAL DOES NOT REST ON THE FLOOR BOARD. SINCE THE CAR WAS RETURNED AND DRIVING FOR WEEKS, I NOTICED THE BATTERY RANGE WILL NOT CHARGE MORE THAN 49 MILES OF ELECTRICAL CHARGE WHEN IT OFTEN CHARGED UP INTO THE 50-60 MILE RANGE PRIOR TO THE INCIDENT. I'VE BEEN DRIVING THE CAR IN SLOWER HEAVY TRAFFIC LATELY AND THIS DRIVING STYLE OFTEN INCREASES ELECTRIC MILEAGE RANGE AFTER A FULL NIGHTS CHARGE. IT WILL NOT DO SO ANYMORE EVEN THOUGH THE ECONOMY MANAGEMENT SCREEN INDICATE MAXIMUM RANGE ECONOMY OF OVER 250 MPG. I'M A RETIRED GAS TURBINE MECHANIC AND I KNOW A PROBLEM WHEN I EXPERIENCE ONE. I SUSPECT THAT A BATTERY CELL MAY HAVE HAD AN UNCONTROLLED DISCHARGE AND IS NO LONGER ABLE TO ACCEPT A RECHARGE. I HAVE RELAYED THIS INFORMATION TO THE DEALER. NO RESPONSE YET.

UN-COMMANDED VEHICLE ACCELERATION UNDER FULL ELECTRIC DRIVE MODE (TWICE). WHILE DRIVING STEADY AROUND 65 MPH ON THE FREEWAY (NO CRUISE CONTROL USED), A SLIGHT STEP ON THE ACCELERATOR, CAUSED THE CAR IMMEDIATELY ACCELERATED UP TO 88 MPH (DASH SHOW LARGE ELECTRICAL DRAW OF BATTERY POWER). STEPPING ON THE BRAKE, USING THE REGEN PADDLE ON THE STEERING WHEEL AND REPEATED PRESSING THE CRUISE CONTROL POWER DIDN'T DISENGAGE THE POWER SURGE. CAR WOULD ACCELERATE WHEN BRAKE PRESSURE WAS LIFTED. AFTER REPEATED HARD PRESSING OF THE BRAKE PEDAL, THERE WAS A "CLACK" SOUND FROM BELOW THE DRIVER CONSOLE AND THE CAR RETURNED TO NORMAL. BEING ON THE FREEWAY, I WAS NOT ABLE TO PULL OVER AND RESTART/REBOOT THE CAR. I CONTINUED TO DRIVE CAUTIOUSLY, MONITORING THE CAR AND LEFT THE FREEWAY FOR SURFACE STREETS. EVERYTHING SEEMED TO BE OKAY UNTIL I CAME TO A COMPLETE STOP BEHIND TRAFFIC. WHEN TRAFFIC STARTED MOVING AGAIN, I LIGHTLY DEPRESSED THE ACCELERATOR PEDAL AND THE CAR BEGAN ACCELERATING QUICKLY ON IT'S OWN. SEVERAL HARD PRESSES OF THE BRAKE PEDAL AND THE CAR RETURNED TO NORMAL. THIS SECOND INCIDENT WAS NOT AS VIOLENT AND THE FIRST AND THERE WAS NO "CLACK" SOUND FROM BELOW THE DRIVER DASH AS WITH THE FIRST. THIS IS WORRISOME AND CANNOT BE RELATED TO THE CRUISE CONTROL SINCE IS WAS AT A STOP AND CC ISN'T SUPPOSED TO ENGAGE UNDER 25 MPH. THE REST OF THE SEVERAL MILES TO MY WORK WAS UNEVENTFUL. I'VE CONTACTED THE DEALER ABOUT THE SAFETY OF DRIVING IT OR HAVING IT TOWED. WAITING FOR THEIR RESPONSE. I IMAGINE THE ON-BOARD COMPUTER WOULD'VE STORED TODAY'S DRIVING DATA.

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.

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.
