The contact owns a 2018 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The check engine warning light illuminated. Shortly afterward, the message "Reduce Propulsion, Engine will not Start" was displayed on the instrument panel. The vehicle was towed to a local dealer where it was diagnosed with a defective EGR valve. The contact was informed that the EGR valve needed to be replaced. The vehicle was not repaired due to the cost and lack of parts availability. The vehicle was towed to the residence. The contact believed that the cause of the failure was related to high temperatures. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

Driving on gas on the highway, the adaptive cruise control suddenly disabled with a "Reduced Propulsion" message on the dash and a check engine light. The car started struggling in its propulsion. We found an AutoZone and scanned the codes, and multiple were returned. A Google search pointed us to the "walk home" fuse, which indeed had been blown. Replacing that fuse and disconnecting/reconnecting the battery eliminated the errors. Less than a week later during highway driving (the next time the battery charge was used up and it switched to the ICE) I got another check engine light, but this time without the "reduced propulsion" message. Scanning at AutoZone again revealed a P0404 message referencing the EGR valve. Due to the limited availability of the part I have called into Covert Bastrop (Bastrop, TX) and am waiting to hear back on their ability to fix the car.

The issue started with a forward push while lowering my speed while coming to a stop. It then progressed to a trembling engine. Then it progressed to the car struggling to effectively switch from electric to gas and back. It then would only be usable on electric range and the engine would not start and would be greyed out. Now, it only works on engine mode, it uses fuel like a pick up truck, it loses power while driving due to trying to switch to electric mode and back, and it struggles to accelerate. It will do it while idle as well as while driving 45mph and up. It barely has any propulsion power and I have to turn my hazards on any time I am going to accelerate. If I brake hard the engine will shake violently and then shut off. I then have to switch gears from drive to park or neutral to park to drive to reengage the engine. Recently it has turned on all the accessories but the ev and the gas is greyed out and there is zero propulsion power. I replaced the 12v battery thinking it might have been dying and it still has the same issue. I read about the class action lawsuit for the BCEM and have made an appointment the dealership but when I told them what was wrong with it the said we need to wait for the diagnostics.

On [XXX], while driving on [XXX] in Virginia, the check engine light came on in my Chevy Volt. A message on dash said that there was reduced propulsion, and the gas engine quit running. The car switched to battery power, which would not have lasted long enough to get us home. At this point, we were stranded on a very busy highway which seemed quite dangerous. Using battery power, we were able to get off the highway. We then made arrangements to have the car towed, approximately 150 miles to a car dealer/repair business in Frederick MD. The vehicle was checked out by the car dealer who identified the EGR valve as the problem. However, they did not know when the part would be available , and still, 4 weeks later, do not have any date for availability of the broken part.

On 9/18/24 I was driving my Chevrolet 2018 Volt on a freeway, traveling at approximately 55 mph while starting to exit the freeway. In the middle of fast-moving traffic, on the freeway offramp and starting to decelerate, the car suddenly displayed a message saying "Propulsion Power is Reduced." A micro-second later, the displayed message changed to read "Action Required: Shift to Park" and in that moment I lost control of the car's powertrain. I continued to break, coming to a slow stop in the middle lane of a multi-lane offramp, with other cars speeding past and around me. I attempted to power the car down and reboot it, moving the gear shift into "Park" position as instructed, but nothing changed. The car remained totally inoperable. I was on a slight decline and noticed the car moving forward pulled by gravity, so I steered the car to the farthest right of the offramp/parallel street, where I put my hazard signals on and requested the car be towed to a mechanic. I was endangered because the car lost entire propulsion while in the middle of fast-moving freeway traffic, and fellow motorists were endangered as well. I have learned that this same behavior occurs routinely with 2nd generation Volts; that there is a special bulletin related to the car's BCEM *and* a related class-action lawsuit posed against GM/Chevrolet. I requested Chevrolet take preemptive action to repair the BCEM, as I am fearful the issue will repeat and cause additional danger to myself and fellow motorists, but Chevrolet says they cannot repair the part until it is diagnosed as defective... which will occur when/if the part fails again, and I'm already in danger.

PE23022 · 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.
