2017 Chevrolet Volt fuel system problems

Filed Oct 9, 2026 · Electrical, Fuel system · NC

My 2017 Chevrolet Volt, with 97,758 miles, experienced a failure that rendered the vehicle inoperable. The vehicle would not start or operate normally. The vehicle was taken to an authorized Chevrolet dealership for diagnosis. After several days, the dealership confirmed that the Battery Energy Control Module (BECM) had failed. The dealership quoted approximately $2,500 for replacement, including parts and labor. This failure presents a serious potential safety concern because BECM malfunctions can result in loss of propulsion, reduced power, or an inability to restart the vehicle, potentially leaving drivers stranded in unsafe locations. General Motors has previously recognized BECM failures in certain Chevrolet Volt vehicles and established a special coverage adjustment for affected vehicles. However, despite my vehicle experiencing the same diagnosed component failure, GM informed me that my VIN was excluded from the coverage program. I contacted General Motors directly and opened a case. GM confirmed that my repair would be considered an out-of-pocket expense and advised me to report the failure to the federal safety agency. I believe this failure warrants investigation because vehicles experiencing the same defect should be evaluated regardless of whether their VINs are currently included in GM’s existing special coverage program. The failed BECM has been diagnosed by an authorized Chevrolet dealership. The vehicle’s current repair status and availability for further inspection can be confirmed with the servicing dealership.

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.

2017 Chevy Volt, lost propulsion and stalled on a highway in 3 separate instances. GM Case # XXX: The first instance, in late 2021, resulted in a BECM replacement. The following instances, XXX and SXXX, had the exact same symptoms: loss of propulsion on highway, shift to park, full charge but 0 range, check engine light. GM Case # XXX: In March the vehicle was towed to Haselwood Chevrolet in [XXX] and they told to check for BECM issues. The dealership refused to include the customer description of the failure on the highway, or acknowledge there was a possible BECM issue, since they said there was no BECM code. The failure presented as a classic intermittent BECM thermal failure. They failed to follow GM's diagnostic tree for an intermittent communication loss, as per GM Technical Service Bulletin PIP5812. Because of that diagnostics failure, I am now completely disabled, again, at [XXX],191 miles, 6 months later. This is a single, continuous warranty failure spanning from March through Sept 2026. GM Case # XXX: Due to previous misdiagnosis, I am awaiting GM’s pre-approval or referral for a rental car as covered by GM Special Coverage Program XXX, before having the car towed to Ruddell Chevrolet in [XXX]. I live a 2 hr round trip from [XXX] and am stranded without a loaner or rental. The tow truck is my way to the dealership to get a rental. If the BECM was recalled, these last two instances could have been prevented and I would not have had to fight tooth and nail with dealerships and GM for coverage, towing, and rental reimbursement, yet again. Please issue a recall on the Volt 2017 BECM and any BECM replaced before the soldering issue on these parts was corrected to prevent future dangerous failures and high levels of customer inconvenience and frustration.

While driving down highway rapidly slowed to 15mph. "reduced propulsion" was displayed with significant battery and gas left. Caused cars to swerve and pile up behind me. The car was inspected by dealer and received a variety of U26XXX codes. Dealer states its a faulty BECM. There was no warning lights on before the incident and have had no issues till then. We were lucky this was during the day. Nighttime would have been a terrible accident with oncoming traffic. Dealer is not wanting to cover BECM repair from GM Special Coverage Bulletin N232432680 that was investigated by your organization a couple of years ago.

In March 2026, our 2017 Chevrolet Volt (89,300 miles) would not charge nor start, and had to be towed to an authorized Chevrolet dealership in Portland, Oregon. The dealership diagnosed an internal fault in the Battery Energy Control Module (BECM) producing U26XX diagnostic trouble codes, per GM bulletin #18-NA-261, and replaced the BECM under GM Special Coverage N232432680 — GM's field remedy for a known BECM defect affecting 2016–2019 Volts that causes reduced power, no-start, or no-charge conditions (the subject of the federal safety agency investigation PE23022).The remedy failed immediately. On the day the vehicle was returned to us (March 26, 2026), the check engine light illuminated while driving home on public roads, and the vehicle failed to charge that same night — the identical condition it had before. It was towed back to the dealership. The dealership's second work order confirms in writing that the vehicle "will not start after previous repairs and is having the same issues," and attributes the failure to the high-voltage battery contactor. The dealership informed us the part is no longer produced and cannot be obtained, advising that the vehicle be scrapped. Safety concerns: (1) after the repair, the dealership returned the vehicle to us as fixed, and we drove it approximately 26 miles home on public highways in traffic, unaware the defect was still present — the check engine light illuminated during that drive. This defect is the subject of the federal safety agency investigation PE23022 into sudden loss of propulsion, we unknowingly operated a defective vehicle in conditions where that failure could have occurred at highway speed; (2) GM's official field remedy for this known defect (Special Coverage N232432680) failed within hours of being performed; and (3) the parts required to complete the remedy are reportedly discontinued, leaving a known safety defect permanently unrepairable.

While driving at highway speeds over 100 miles away from home with my child in the vehicle, the car experienced a sudden, catastrophic loss of propulsion power and entered 'Propulsion Power Reduced' mode, dropping vehicle speed immediately and creating an extreme hazard with high-speed highway traffic. A full computer scan revealed active diagnostic codes U2603 through U2624, confirming an internal hardware communication failure of the Battery Energy Control Module (BECM). This matches GM Technical Service Bulletin 18-NA-261. The vehicle has over 150,000 miles, but I have only owned the car since January. This is a known, systemic manufacturing defect (cracked internal circuit board solder joints) that creates a critical safety liability regardless of vehicle mileage. GM has refused to remedy the safety defect due to the mileage limit.

I was not going to put in a complaint about this failure but after learning about GM creating a special extended warranty program for this issue, I felt it should be addressed and treated as a recall. The battery energy control module (BECM) failed on my 2017 Chevrolet Volt at exactly 170,000 miles in December of 2024, leaving me in a dangerous position on the roadway and almost causing me to be rear ended due to losing the ability to accelerate. I had no choice but to have the vehicle towed to a dealership where it was eventually repaired with an out of pocket cost of $1900. My vehicle was not eligible for the extended warranty program which I find to be unacceptable.

Failure of Battery Energy Control Module (BECM), within the high voltage battery. Vehicle is unable to charge and sets “reduced power” message. GM released special coverage bulletin for this issue (N232432680), but this vehicle is not listed due to which state it was registered. Continued failure of the BECM will lead to inoperability of the vehicle.
