I was driving on the freeway and the engine turned off. I was able to continue driving as the hybrid system still had some charge to continue powering the car. I had to get the EGR valve replaced. No warning lights prior to this occuring but had check engine light after. Car would not shift into drive nor would it accept a charge for the main drive battery. Had to be towed to a shop and resulted in getting the Battery Energy Control Module (BECM) replaced.

The car started stating "put in park" every time I would try to put the car in drive. I would shift back and forth from park to drive over and over and I could get it to clear. One time it lost all power and had zero control. Sat on the side of the road for an hour. Shifting back and forth until it stopped and let me engage the drive. The last time it happened in a parking lot and it would just say"shift to park" I couldn't get it out of park. Had to have the car towed. Tow driver had to drag the car on the flat bed with a wench because it was stuck in park. Had the vehicle repaired. Replaced an electronic control module that had previous service bulletins on but GM would not cover the repairs. I was lucky I was not injured our involved in a wreck when I experienced these issues. I was not aware I could file a report about this until I read there was an open investigation on the same issue I had.

The contact owns a 2017 Chevrolet Volt. The contact stated that the vehicle failed to start up after multiple attempts. Due to the failure, the vehicle was towed to a local dealer where the mechanic informed the contact that the 12-volt battery needed to be replaced. After the battery was replaced, the contact stated while driving 65 MPH, the Propulsion Power reduced message was displayed. The vehicle was towed to AutoNation Chevrolet West Colonial (3707 W Colonial Dr, Orlando, FL 32808) where the contact was informed that the battery had failed for a second time within two weeks and needed to be replaced. After the second 12-volt battery replacement, the vehicle started making an abnormal cranking sound while the vehicle independently surged and then lost power. The contact stated that an unknown power failure message was displayed on the instrument panel.

Sudden loss of electric propulsion on the freeway while my wife (pregnant at the time), my son (1 year and a half) and I were driving. The car was still driving but was unstable when steering and with weak braking. The dealership identified the issue as BECM failure and the part was changed. 3. A couple of months later the car would not start at all leaving me stranded at work. The car was towed to the repair shop. The dealership diagnosed BECM failure again. 4. There was no warning indication or message prior to these issues. 5. The vehicle was only inspected by the dealership to the best of my knowledge.

My Volt will suddenly lose propulsion. The air conditioner will stop working and the car will not properly accelerate. There has also been multiple occasion where the car will not power on. Additionally, there has been multiple occasions where the car won’t charge. The failed component is most likely the battery engine control module. My safety and that of others is at risk because of the sudden loss of power and inability to maintain highway speeds. The issue was confirmed at the dealer. The check engine light goes on even after erasing codes, and there are 13 permanent codes related to this issue with no direct resolution. This is a recurring problem.

The car will occasionally lose power when driving on battery. In my experience this most often occurs after turning, but can occur seemingly randomly at other times. It's a frightening experience because you just don't know when it will occur, what you'll be doing, and how it will impact other drivers. I spent $8k trying to fix the issue and took it to two dealership issues who said the transmission needs to be replaced. We got the transmission replaced, but the issue persists. The issue happens daily. I don't know what component failed, but yes, it is available for inspection. Safety is put at risk because the car randomly loses power while driving and switches to gas mode. Yes, the problem has been seen by a local dealer. No, the vehicle or component has not been inspected by the manufacturer, police, or insurance rep. No, there are no indicators of the failure before or after the loss of power.

Sometimes when the vehicle powers on, it will not engage to drive in gas or electric mode when fully charged or with a full gas tank. Also sometimes while driving, it will say "gas mode not available propulsion limited". It frequently says "charging not available" as well. This is an on going, intermittent, problem.

I was making a left turn at a light and the vehicle suddenly popped up “shift to park” warning on the dash and simultaneously lost power. The vehicle would only roll under what momentum was generated prior to the warning. Luckily I was able to get through the turn and coast safely off to the side of the road. Chevy volt is currently at the dealership being assessed. They are telling me I will need a new 12v battery and new gear shifter for $1100.00. These were replaced, but the dealership called and told me I will now need a new ECM, or something like that, for an additional $2400.00. Car is currently at Ricart Chevrolet in Dublin,OH waiting on my decision. And I’m being told the part needed is on backorder and may be a month to arrive. After researching this, it seems Chevy knows about this issue and seems very irresponsible to knowingly put volt owners in harms way. Needless to say I’m not happy and feel something should be done by Chevy to rectify the situation.

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.
