When I first purchased the car (used around 30,000 miles), I began to have electrical and propulsion issues where the engine would turn off. After Chevy refused to warranty or lemon the car, eventually the electrical/hybrid issue repeated and caused cooling issues with the car and then water pump went bad. while chevy still refused to fix the hybrid and battery issues, that continued issue and then the water pump failing from it then caused overheating that then broke the head gasket

The contact owns a 2017 Chevrolet Volt. The contact stated while driving 30 MPH, the message “Loss Of Power Proportion" was displayed, and the vehicle stalled. The contact was able to veer to the side of the road. The vehicle was able to restart. The contact was able to drive to the residence; however, the vehicle failed to restart while in the garage. The contact stated that upon investigating the failure online, he became aware that the failure mostly occurred in cold weather. As the weather became warmer, the contact was able to restart the vehicle. The vehicle was taken to the dealer, where it was diagnosed that the Battery Energy Control Module (BECM) had failed and needed to be replaced; however, the part was not available. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part was not available. The failure mileage was approximately 36,436.

Loss of power propulsion while driving Eventually vehicle completely stoped. After doing some research this is a common occurrence. Highly dangerous and it seems the manufacturer is aware but ignoring the problem. This problem can cause accidents and also leave people stranded in isolated areas.

When I got home at 11:50 am at March 4, 2023. The shift-to-park error message came up and prevented shutoff and driving. The car kept running in my garage which pause great danger to my house and my family. The weather is freezing cold with rain and snow. We are scare to stay in the house and afraid of explosion. I contacted Chevy and its dealers. All could not find tech to support. Then I searched on websites. There are tons of complaints that Chevy knows the problem in multiple car modes but resist to make a recall. Also Chevy lost a case due to damage by shift to park error.

BECM failure. Initially, it caused the vehicle to operate in a low propulsion state. However, it now prevents the vehicle from starting. Likewise, I have heard it has stopped the engines from working/shut down the engines while people are driving on the highway.

On Sunday night, I was driving around 65 mph on the 405 freeway to take my friend to the airport. I noticed that the car started to give a weird feedback sensation on the pedals and had started to jerk us forward. As I merged onto the two-lane on ramp to the 10 freeway, the car started to rapidly lose power and then completely died and went dark. I was unable to use the hazard lights as the car had just gone dark but then it turned back on but would not let me shift it into drive. As I was on a two-lane on-ramp with no shoulder in the dark, we just had to pray that no one would hit us. In doing research, I suspect that this was yet another BECM failure that has been repeatedly happening with this year of Chevrolet Volts. There was most recently a class-action lawsuit filed for this very issue. The car is currently at the dealership awaiting inspection but I am terrified to drive that car again if it even becomes drivable. Especially since there were no warning lights or signs on the vehicle to indicate that this could be an issue and to have it die on the freeway in the way that it did, putting my life and many other lives at risk, I am shocked that there hasn't been a recall for this issue.

Vehicle experienced an unexpected loss of power when the check engine light came on and we had to immediately pull off the road. The vehicle is currently at the dealership waiting on the Battery Control Module (BCM) P/N: 24296900 and we have a Case open with [XXX]. We are told the part is not available, only 14 in stock nationwide, and are not being released as they are reserved already. No expected delivery date for the module. Noticed a class action lawsuit may be in the works.

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.
