I am reporting a suspected Battery Energy Control Module (BECM) failure in my 2017 Chevrolet Volt. My vehicle has experienced multiple symptoms consistent with the known BECM defect documented by General Motors, including intermittent failure to start, reduced propulsion power, and failure to operate on electric power despite the high-voltage battery being fully charged. When the vehicle did start, it would run using the gasoline engine instead of the fully charged battery. The vehicle also experienced reduced propulsion power, limiting acceleration and creating a serious safety concern, particularly when merging into traffic, crossing intersections, or driving at highway speeds. The intermittent starting failures also create a risk of becoming stranded. My vehicle has generated multiple diagnostic trouble codes associated with these malfunctions, which are available for review. These symptoms are consistent with those identified in GM Technical Service Bulletin 18-NA-261 and Special Coverage Program N232432680. GM established extended BECM warranty coverage of 15 years or 150,000 miles for eligible 2016–2018 Chevrolet Volts. However, despite my vehicle being a 2017 model and experiencing the same documented failures, my VIN is excluded from this coverage. the federal safety agency previously investigated this defect under PE23022 and closed its investigation following GM’s implementation of extended coverage. I am requesting that the federal safety agency investigate why my vehicle is excluded despite exhibiting the same known safety-related symptoms and whether GM’s coverage should be expanded to include similarly affected vehicles.

3rd failure of EGR valve (GM part 12691147, superseded by 19436521) on this vehicle. 10/10/2019 at 11,336 mi: Check Engine Light and Driver Information Center displayed "Loss of Propulsion" message; EGR valve diagnosed as cause and replaced by dealer under warranty at no cost. 11/2023 at approx. 30,000 mi: EGR valve failed again; dealer stated OEM part was no longer available from manufacturer due to supply shortage and installed a third-party replacement part; repair not covered, paid out of pocket. 8/26/2026 at 49,864 mi: EGR valve failed a third time; a used, refurbished part was sourced due to continued unavailability of a reliable new OEM part, with repair scheduled for 9/14/2026, again paid out of pocket. This is a known, recurring failure on 2016-2019 Chevrolet Volts, referenced in GM Technical Service Bulletin 19-NA-206. The failure does not present only as an emissions fault — it triggers a "Loss of Propulsion" driver warning, indicating a direct impact on the vehicle's ability to be safely driven. Sustained unavailability of the OEM part is forcing owners toward third-party or used/refurbished parts of unknown long-term reliability, at repeated cost to the owner, in order to keep the vehicle operable.

Received "reduced propulsion" message, with no engine detected. Car slowed to a near stop while driving on the Interstate highway. Very dangerous to have that suddenly happen. Message popped up randomly with no prior warning.

Brought car into Chevrolet dealership for intermittent “miss” when driving. Dealer diagnosed it needed an EGR valve replaced at a cost of around $4,000.00 which is a significant portion of the cars value.

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving at an undisclosed speed or while starting the vehicle, the check engine warning light was unexpectedly illuminated. Additionally, there were several error codes provided through the Mobile App for engine-related failures. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the federal safety agency Hotline for assistance. The approximate failure mileage was 92,000.

I am reporting a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024, November 25th, 2025, January 11th, 2026, and February 12, 2026 while driving to work, both times I experienced a loss of propulsion power on the highway, placing my safety at risk and lost all power in a traveling lane of traffic. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. The reduced propulsion power while driving on the highway, coupled with the illumination, I urge the federal safety agency to investigate this matter thoroughly to ensure the safety of Chevy Volt drivers and passengers. It is imperative that General Motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

Several years ago, when I was driving the vehicle, I got a sudden "reduced propulsion alert" and the onboard coolant temperature gauge showed a significant spike in temperature. To avoid overheating, I had to pull over on the side of the highway. In the onboard fuse box, there was a blown F3 fuse. I replaced the fuse and the same issue happened again last year. After some online research, it is clear that the EGR valve failed. Unplugging the valve and replacing the fuse has returned the vehicle to normal operations, but it's now out of compliance with local emissions regulations. GM has failed to properly produce replacement parts. As of Feb 11, 2026, a local GM dealer in Bloomington, IN quoted a backorder and unclear wait time on a replacement part and quoted me at $2,000+ just for the part. If not for my quick thinking, this part failure could have overheated my vehicle causing extensive damages. GM has failed to produce enough replacement parts and given the safety issues associated with a blown fuse and overheating, the federal safety agency should order a recall on this part and force GM to replace the parts for owners. This is a widespread problem documented among Volt owners, and the only stopgap issue is to drive the vehicle out of compliance with local emissions rules.
