2017 Chevrolet Volt Owner Complaints

I would like to file a formal complaint. 2017 Volt suffered an EVAP purge line hole due to the failure of the remedy applied under NHTSA Campaign ID 19V891000. Recall #N192273600 was completed on my vehicle in 2020 by installing a protective bumper. That bumper failed by shifting out of place, and the A/C line has now rubbed a hole completely through my EVAP purge pipe—the exact failure the recall was designed to prevent. I called GM and asked for a Goodwill Policy adjustment, and they refused as my dealer had already offered me a $500 reduction to the repair. The total cost of the repair is over $2700.

3rd failure of EGR valve (GM part 12691147, superseded by 19436521) on this vehicle. 10/10/2019 at 11,336 mi: Check Engine Light and Driver Information Center displayed "Loss of Propulsion" message; EGR valve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.

Chevrolet is denying that my car is included in Special Coverage Bulletin N232432680, because of where it was built. The car is now in Kentucky, which is not a CARB state. Was the reason for a vehicle not to be included in the bulletin because it would be included under CARB? It seems like a loophole they are using not to fix my car. Am I wrong?

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 NHTSA 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 NHTSA 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. Supporting documents uploaded: dealer repair orders, and the GM warranty history of the N232432680 repair

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.

BECM failure. My car is available for inspection upon request. This car has unexpectedly stopped adequately accelerating all of a sudden while on the road! This problems has been confirmed by the dealership. The manufacturer has not inspected it. Not much warning. I found out SOME not ALL chevrolet volt 2017 users got their BECM replaced without cost because it is a WELL KNOWN ISSUE with the car. Chevrolet did not provide extended warranty for all chevrolet volt users even though it is an issue with most volts. I do drive much. I got the car when it was brand new and in 8 years accumulated 77k miles. If I had known all of the cars would have had this safety issue I would not have bought the car in the first place. Chevrolet expects me to pay 2500 out of pocket for something they know is faulty and dangerous in their vehicles.

Coolant was found inside the Lithium-Ion battery module when the dealership opened it to repair a different issue. They condemned the battery on the spot. There was no damage to the battery module. All PMs were performed at Chevrolet dealerships throughout the life of the car. All recalls were fixed. Including the BECM replacement the car is known have problems with. Car had 127,000 miles on it. One of the service reps even admited that he's seen it on multiple cars and that it is a manufacturing problem. Dealership said the repair is $29,000. The car was $35000 new 10 years ago. Thank God there was no fire, I drove my family around in that car for years. The dealership won't even let me see the diagnosis report online anymore...

Three separate high-voltage battery section failures within one year, each causing complete loss of propulsion. Two occurred at freeway speeds on [XXX]. FAILURE 1 ([XXX]): Vehicle lost propulsion. Dealer diagnosed DTC P0AFA (low voltage), failed cell in Battery Section 3. Section 3 replaced under GM Special Coverage N232432680 (BECM, 15yr/150k). Vehicle out of service approximately six months awaiting GM authorization and parts. FAILURE 2 ([XXX]): Vehicle lost propulsion on [XXX] at night at freeway speeds. Required towing. Dealer diagnosed DTC P0AFA, Cell 85 at 1.85V in Battery Section 1 (different section). Section 1 replaced under same Special Coverage. Vehicle returned Jan 28, 2026. FAILURE 3 ([XXX], ~300 miles after Failure 2 repair): Vehicle again lost propulsion on the freeway with check engine light, then progressed to no-start condition. Towed to dealer. Diagnosed Feb 20, 2026: DTC P0AFA, Cell 57 at 1.5V in Battery Section 2 (GM minimum spec 2.5V). Third distinct section failure. Vehicle remains at dealer awaiting GM repair authorization as of filing date. SAFETY CONCERN: Loss of propulsion at freeway speeds is an immediate safety hazard. During the Nov 2025 event, the vehicle lost power on [XXX] at night in active traffic. The progressive failure pattern (three different sections failing sequentially in the same pack, identical DTC) suggests a systemic defect rather than isolated component failures. Prior section replacements have not resolved the underlying problem. Vehicle has been usable approximately 20 total days in the past 12 months. All repairs performed or pending under GM Special Coverage N232432680. GM Case [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 National Highway Traffic Safety Administration (NHTSA) 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, NHTSA 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.

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving approximately 35 - 40 MPH, the message stating that the propulsion was reduced was displayed, and the check engine warning light was illuminated. The contact continued to drive the vehicle, and the vehicle unintendedly decelerated. The contact arrived at the destination and parked the vehicle, and the message “Shift to Park” was displayed even though the gear shifter was in park(P). The message “Charging Unavailable” was displayed. The contact stated that while charging the vehicle, the mileage was reduced from 72 miles to approximately 29 miles during the winter months, and 42 miles during the summer months, while still indicating a FULL charge. The “Shift to Park” failure had occurred twice the previous year, and the vehicle was turned off and restarted to correct the failure. The vehicle was taken to a certified mechanic, who diagnosed that the hybrid power train control module had failed. The vehicle was not repaired. The manufacturer was notified on the website, and a case was filed; however, a representative was not reached. The failure mileage was approximately 26,500.

There is a ongoing problem with the BECM on 2016-2018 volts. Mine is one of them. Contacted Chevrolet and they say my vin isn’t under the extended coverage. I believe it should be and can’t stand they won’t cover my car under warranty. Is there anything you can do?

Jan 24, 2026

My car started having issues with the hybrid system, with fault alerts related to the drive motor control module, hybrid powertrain control module, and battery energy control module in the transmission, and the vehicle is available for inspection if needed. The engine light had been on for about a week, and I was waiting for availability at work to take it to a mechanic. While driving around 70 mph on the highway, a “Propulsion Power Reduced” message suddenly came on and the car started limiting its speed. As I kept driving, the power continued to drop, making it unsafe to stay at highway speeds and putting both me and other drivers at risk since the car couldn’t keep up with traffic and could slow down unexpectedly. I took it to an independent mechanic who confirmed the issue and warned me it was dangerous to drive because the speed would keep decreasing as power dropped. So far, only an independent mechanic has inspected it. After doing some research, I found this is a very common problem with 2016–2018 Chevy Volts, with many people reporting similar situations where their cars lost power or started jerking at high speeds and they had to pull over.
