ACTION REQUIRED SHIFT TO PARK APPEARS ON THE DASH WHEN I ALREADY HAVE THE CAR IN PARK AND ATTEMPT TO SHUT IT OFF. THIS DOESN'T ALLOW ME TO TURN THE CAR OFF OR LOCK IT AND I HAVE TO TURN THE CAR ON AND OFF MULTIPLE TIMES FOR THE SENSOR TO READ. THIS HAPPENS EVERY TIME I ATTEMPT TO PARK AND TURN THE CAR OFF AND CAN TAKE UP TO 20 MINUTES TO GET IT TO STOP. IT MAKES ME FEEL UNSAFE TO BE IN MY CAR WHEN THE CAR DOES NOT READ THAT IT'S PARKED CORRECTLY, ESPECIALLY IF I AM PARKED AND CAN'T GET THE CAR TO TURN OFF. *TR

WHEN MERGING ONTO THE HIGHWAY, I PRESSED THE ACCELERATOR, BUT THERE WAS A SIGNIFICANT LAG TO GET UP TO HIGHWAY SPEEDS. WITH THE WHEELS BEING POWERED BY THE ELECTRIC ENGINE, THE RESPONSE HAD ALWAYS BEEN INSTANT, UNTIL TODAY. AFTER ARRIVING AT MY DESTINATION, I TURNED MY CAR OFF AND BACK ON, BUT THE CHECK ENGINE LIGHT CAME ON AND THE DASH READ "SHIFT TO PARK," EVEN THOUGH THE CAR WAS IN PARK.I TURNED THE CAR OFF AND ON AGAIN, AND THIS TIME I WAS ABLE TO SHIFT THE CAR TO DRIVE, BUT THE CHECK ENGINE LIGHT REMAINED ON. THE ACCELERATOR DID NOT PROPEL THE CAR AND THE STEERING WHEEL WAS LOCKED. I AGAIN SHIFTED TO PARK AND TURNED OFF THE CAR. I WAITED A FEW MINUTES AND STARTED THE CAR BACK UP, AND THE FUEL ENGINE TURNED ON THIS TIME, BUT I RECEIVED A MESSAGE SAYING THE CAR WAS NOT CHARGING. I WAS ABLE TO DRIVE IT, BUT THE ENGINE WOULD NOT SHUT OFF, AS IT USUALLY DOES AFTER THE BATTERIES ARE SUFFICIENTLY CHARGED. I DROVE ABOUT 3 MILES ON SURFACE STREETS AND THE FUEL ENGINE REMAINED ON THE ENTIRE TIME. THERE WAS A SIGNIFICANT AMOUNT OF LAG IN RESPONSE TIME BETWEEN PRESSING THE ACCELERATOR AND THE BATTERIES CHARGING UP ENOUGH TO PROPEL THE CAR, CAUSING AN UNSAFE RESPONSE TIME IN MERELY GETTING THE VEHICLE GOING AFTER STOPPING AT A LIGHT AND TURNING ONTO A NEW STREET.

TODAY IT DIDN'T LET ME SHUT IT OFF EVEN AFTER SHIFTING IT TO A GEAR THEN BACK, WIGGLING THE SHIFTER, I EVEN TRIED TO LEAVE THE CAR WITH THE KEYS AND IT WAS STILL ON WHEN I WENT BACK OUT. (I HAD LOCKED THE DOOR WITH THE REMOTE). AND THE LIGHTS WERE STILL ON. I GOT IN THE CAR AND BACKED IT OUT AND TRIED IT AGAIN AND THANKFULLY THIS TIME THAT WORKED. THIS IS TRULY A PROBLEM THAT NEEDS TO BE FIXED AND IT LOOKS LIKE OTHER ARE EXPERIENCING IT, TOO. IT SOUNDS LIKE IT ONLY GETS WORSE. PLEASE DO SOMETHING SO THIS DEFECT IS RECALLED. *TR

MY VOLT PRODUCES AN ERROR MESSAGE: "ACTION REQUIRED: SHIFT TO PARK" AFTER PLACING THE CAR IN PARK AND TAPPING THE POWER BUTTON. AS A RESULT, I CANNOT TURN OFF THE VEHICLE WITHOUT A SERIES OF TURNING THE CAR ON AND OFF AGAIN WHILST SHIFTING BACK AND FORTH FROM DRIVE TO PARK. MY CONCERN IS THAT THIS EXTRA ACTION WILL ONE DAY PRODUCE AN UNINTENDED ACCELERATION INTO A PERSON OR STRUCTURE THAT MAY CAUSE DEATH, DAMAGE OR DISMEMBERMENT TO MYSELF OR OTHERS. I'VE FOUND NUMEROUS REPORTS ONLINE THAT THE ISSUES STEMS FROM A KNOWN PROBLEM INVOLVING THE SHIFT ASSEMBLY BUT MY LOCAL DEALERSHIP REFUSED TO INSPECT THE VEHICLE WITHOUT CHARGING A $160 DIAGNOSTICS FEE THAT MAY INCREASE BASED ON THE ISSUES AT HAND, WHICH I DECLINED. I'VE MENTIONED THAT THIS WAS HEAVILY CATALOGUED ON GM FORUMS AND MY SERVICE ADVISOR AGREED BUT MENTIONED THEY ONLY OFFER NO COST REPLACEMENTS WHEN THE ISSUES HAPPENS UNDER 36K MILES AND I AM AT 44K MILES. A RECALL SHOULD BE INITIATED FOR THE REASONS MENTIONED ABOVE. *TR

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.

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.
