EXCESSIVE CONDENSATION FROM WATER LEAK BELOW THE FRONT PASSENGER FLOOR. IT WAS WITHIN THE BUMPER TO BUMPER WARRANTY, BUT 3 SEPARATE CHEVY DEALERS DID NOT DIAGNOSE OR FIX PROBLEM UNTIL AFTER WARRANTY EXPIRED. ONE DEALER EVENTUALLY FOUND A BAD WELD RESULTING IN A WATER LEAK AND SEALED IT. UNFORTUNATELY, THE LEAK HAS RETURNED AND THERE IS A LOT OF WATER BELOW THE FLOOR AGAIN. THIS REQUIRES REMOVING THE SEATS, TRIM, CARPET, AND FINDING ANOTHER BAD WELD.

WHEN ATTEMPTING TO TURN OFF THE CAR IT SAYS "ACTION REQUIRED: SHIFT TO PARK" AND WILL PROCEED AS BEING LEFT ON, DESPITE BEING IN PARK. THIS OCCURS ABOUT 70% OF THE TIME THE CAR IS DRIVEN AND TAKES SEVERAL TRIES OF TURNING ON THE CAR, MOVING, PARKING, AND TURNING BACK OFF BEFORE THE ENGINE SHUTS OFF WITHOUT THIS WARNING.

THE VEHICLE DOES NOT RECOGNIZE IT HAS BEEN SHIFTED INTO PARK, WHICH DOES NOT ALLOW THE VEHICLE TO BE TURNED OFF. DASH DISPLAY STATES 'ACTION REQUIRED, SHIFT TO PARK'. THIS HAPPENS CONSISTENTLY AND IS A KNOWN ISSUE BY CHEVROLET. YET THEY HAVE NOT ISSUED ANY RECALL. IT IS KNOWN AS THE 'SHIFT TO PARK' ISSUE. THERE IS NO WORK-AROUND FOR THE ISSUE OTHER THAN SHIFTING BACK AND FORTH INTO GEARS, SOMETIMES HUNDREDS OF TIMES, BEFORE THE ERROR CLEARS. FOR EXAMPLE: MY WIFE TOOK MY DAUGHTER TO AN EMERGENCY ROOM AND COULD NOT GET THE VEHICLE TO TURN OFF. SHE TRIED TO CLEAR THE ERROR A FEW TIMES BEFORE HAVING TO LEAVE THE VEHICLE RUNNING IN THE PARKING LOT.

KEEP GETTING ACTION REQUIRED MESSAGE "SHIFT TO PARK" EVEN THOUGH THE CAR HAS BEEN POWERED OFF. IT TAKES ABOUT 5 TRYS NOW TO ACTUALLY POWER OFF THE CAR, HAVE TO REPEATEDLY TURN THE CAR ON AND OFF TO ACTUALLY POWER OFF THE VEHICLE.

IF I PUT THE SHIFTER BACK INTO THE "L" POSITION SEVERAL TIMES, EVENTUALLY IT WILL SHUT OFF. THIS PROBLEM IS GETTING WORSE BY THE DAY. NOW I NEED TO REPEAT THIS PROCESS OF SHIFTING BACK AND FORTH MANY MANY TIMES TO GET IT TO SHUT OFF. THIS IS THE 2ND TIME IT HAPPENS TO THIS CAR. GM REPLACED THE SHIFT ASSEMBLY ONE YEAR AFTER I PURCHASED THE CAR TO FIX THIS EXACT SAME PROBLEM. THE CAR WAS PARKED WHEN THIS HAPPENED.

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.
