The vehicle suddenly, and unexpectedly lost propulsion while driving. The vehicle is no longer able to turn on or drive. I contacted several Chevy official dealers and took the car in for repair. They said it is a problem with the hybrid battery system. But the car is no longer manufactured and parts are no longer available. So I am now stuck with a car that is non-operational and not repairable.

I pull into a parking space. Place the gear in Park and then attempt to turn the car off by pressing the Power button. I then receive a warning message informing me: Action Required Shift Car to Park The car gear is already in Park and the driver display console also shows the car is in “P” (Park). The car will not lock. I have to turn the car on and off and switch the gear back and forth placing back into P (Park) several times until the car realizes it’s in Park and allows me to turn it off. This started happening when the car hit about 36,000. The car has approximately 40,000 miles now.

I have owned my 2017 Volt since November of 2016. I drive about 200 miles a week and currently my mileage is at 109,000 (9,000 miles PAST the warranty period). My car did not start one morning and had to have it towed to my local GM dealership. They diagnosed it with a bad BECM and a repair bill of $1,400. They have no estimated time on when the part will be shipped. It is unacceptable to not have an ETA for a critical part or the vehicle. I have read on many forums that the BECM is a known failure for the 2017 Volt.

Vehicle went to low propulsion mode and would not move at a stop light during rush hour traffic. After many trial and errors restarting the car it finally moved under low propulsion mode. We were almost hit from behind many times because of people at the last minute turning around a stalled car... GM diagnosed the issue as a bad BECM (battery energy control module). Our service rep said it is a very common issue with this car and that they have a few others waiting for a replacement part. I am at month 2 waiting for my vehicle to get fixed.

Diagnosed with a failure of Battery Energy Control Module 24296900. Multiple complaints of the same issue from other owners. 5 other same model cars at dealership waiting for the same part. Estimated arrival is 8-12 weeks. This has been a well documented problem since 2018, and Chevrolet has released a TSB acknowledging the issue, and potentially loss of control and stranding.

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.
