2016 Chevrolet Volt Electrical Problems

I purchased the above-listed 2016 Chevrolet Volt through Carvana, relying on the contractual promise that the BECM was covered under Special Coverage N232432680 for up to 15yrs or 150k miles. The vehicle has suffered persistent, severe mechanical and electrical issues resulting in a prolonged loss of use: 1. Initial Breakdown and Delivery: The vehicle originally had a Reduced Propulsion Power Alert on Monday [XXX] around 8pm and nearly caused me to be rear ended on a major road due to accelration issues. It then officially broke down on Tuesday, [XXX]. It was then delivered to Vic Koenig Chevrolet (1040 E Main St, Carbondale, IL 62901) via Tow By Freedom Towing the following Friday, May 29, 2026. 2. Delayed Work Start & Shop Stay: Vic Koenig Chevrolet was able to officially begin diagnostic and repair work on Wednesday, June 3, 2026. The facility held the vehicle for several weeks to address the failures. 3. Brief Release and Immediate Re-Breakdown: I picked up the vehicle upon its supposed completion on Tuesday, June 16, 2026. Then less than 24 hours later, on Wednesday, [XXX], the vehicle suffered a recurring breakdown and had to be returned to the dealership immediately. 4. Wrongful Coverage Denials: On Thursday June 19, 2026, Silver Rock claims representatives issued explicit coverage denials to me via text message. That same day, service representatives from Vic Koenig Chevrolet phoned Silver Rock multiple times to provide diagnostic evidence, But SilverRock repeatedly issued oral denials over the phone. They stated the PCM and BECM were not included in the contract, screenshots of the vontract state the opposite. SilverRock sent this refusal via email to me on June 19. I also contacted GM by phone on Wednesday 5/27/26 and so did the dealership and they refused to cover my vehicle under the Special Warranty for the known issue. I tried to request a cost reduction and they denied it again on 6/22/26. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2016 Chevy volt. It had to be towed to a Chevy dealership because it will not drive. The BECM module has failed, as is apparently the case with so many volt owners. GM, as a result of lawsuits about this car, extended the warrantee to fix the issue, but my vin number is not included in the case. The gar is a brick, and there is no way to fix it now. GM doen't even replace these batteries any more, and most often just buys back the bad vehicles. I still owe 9k on this car and it is useless now. I need help. These are the codes is is throwing.

While I driving in the past week, a warning that "propulsion power reduced" appeared on my dashboard several times. The last time that I had driven the car, the heater would not turn off, and the smell of burnt rubber filled the car and then dissipated soon after. The car would only run in it's gas engine mode, and not switch over to electric mode, as it usually would. The next morning, the car would not start. The dash board would light up as if the car started, but when I shifted into drive, a warning appeared on the dash, "Shift to park", as it would when the car is not running. I could not start the vehicle. After plugging the vehicle in, a warning appeared on the console stating that "Charging is not available". The car was towed to the dealership. Their diagnosis showed that the Battery Energy Control Module had failed and must be replaced. They later confirmed that an electric cable needed to be replaced that was "corroded", but they could not confirm the cause of the corrosion because the cable was disposed of already. After researching online, I found that GM issued a Special Coverage bulletin: N232432680, citing a common malfunction of the Battery Energy Control module in 2016 to 2018 Chevy Volts that "causes a reduced power mode, a no start condition, or a no charge condition." The Special Coverage was to extend the warranty to 15 years or 150,000 miles. After inquiring the dealer about the Special Coverage, they claimed that our car is not covered under the warranty. After calling customer service, they claimed the coverage comes from NHTSA, and GM only issues orders by VIN, and therefore cannot cover the issue. After calling NHTSA, I was told the special coverage is not a national recall, and is internal to GM. The GM dealership still claims that the control module on our car is not covered under the warranty, and have denied the request for a manager inspection or investigation.

Battery Energy Control Module Malfunction. It is a known issue with this system failing on the chevy volt. There is a service bulletin on this problem. 18-NA-261 is the service bulletin. The car will not start and when it does start it has loss of power while driving. Chevy is only fixing certain VIN numbers even thou it pulls up the same codes in their bulletin. Chevy only gave extended warranties to certain VIN numbers also. Extra warranty bulletin N232432680. This is a major component for the high voltage battery which drives the vehicle. The dealership wants $5000.00 to repair this.

Driving at 75 MPH on the freeway the power completely cuts off an a message appears on my dash "Propulsion Power is Reduced" - Pressing the gas barely gives any power, Imagine being in the middle of flowing traffic doing 75 mph to close to 20 mph. Research shows me this is a KNOWN issue with GM and the problem is with the BECM control module. There is also the issue of the EGR valve which apparently is tied into the BECM. I brought to the Chevy dealer and they said the BECM NEEDS to be replace ASAP because GM knows this is a dangerous situation and GM extended the warranty on this part to 150,000 miles. My vehicle is at 152,400 miles and they will not cover this. This is a serious issue that should be a recall that forces GM and Chevy to pay for this fix as it is something they have been aware of for years and it is a major accident waiting to happen. Please make them issue a recall for the BECM fix.

•Vehicle lost power while driving on the highway at speed. The vehicle would not run with gas engine power or EV charge basically died on the road in traffic. After coming to a stop safely but not without some close calls vehicle would not start even with car having fuel of two types in it. •The battery charge would not register, and the car would not start for a little while. Display showed nothing and was only making a dinging sound. Around half hour later the vehicle started, and I drove it to my home and parked it. I have not been driving it as it seems like a safety concern with the battery system and not feeling reliable. I had tried to charge it after the initial event and it did not charge. I did only a little research on cost for battery issues and the cost made me very put off even looking at the car. The car has been sitting sense August of last year. I took the car into a GM repair shop a week ago and the shop told me that the BECM module is weak. I looked this up and found that there is a lot of people having the same issue! Also, there are 19000 cars just like mine who got a recall or Special coverage. I am told I don’t meet the requirements for the coverage even though my car has the issues. They say my VIN is not on the list, clearly this special coverage did not go far enough. There appears to be some gaps in the coverage of this issue there are tons of people having this issue a full recall should be investigated and enacted there is clearly a problem that should be addressed. The fact that most cases do not happen when the car is running seem to put this on everyone’s back burner but people are being harmed financially while GM uses loop holes to not address an issue that could cost people there time, hard earned money, lost wages, even there life if this malfunction causes accidents. There was and is clearly enough to warrant action. Letting GM get away with a half Hearted attempted at fixing this is a crime.

While driving the car displayed “reduced propulsion power” on the dash and then I lost all drive power and could not switch the plug in hybrid from electric to gas engine mode. The vehicle had to be towed to the dealer who stated that the battery electronics control module and perhaps the battery needed to be replaced. The check engine light came on slightly before the incident.

On [XXX] the check engine light turned on in my 2016 Chevy Volt (VIN: [XXX] miles 145,xxx). I was 2 hours from home in the freezing cold snow but thankfully the vehicle allowed me to drive home without any issues (no reduced propulsion power). When I returned to the vehicle to have a diagnostic check the error light disappeared and I was unable to check for error codes. Still no issues driving under EV/gasoline. Later that day, the car stopped going completely, no shifting out of park either. EV range was reporting 0 miles despite having full charge. I plugged in the charger but it would not work (first time this happened), " Not able to Charge" message displayed. After cycling power the EV range was full range and I was able to shift into drive again. These issues were intermittent over 3 weeks, frequently standing me temporarily. After cycling power, opening and closing the door, cycling power again, the car would function normally and I could drive under battery or gasoline power. I managed to capture these error codes while the MIL light was on: U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623, U2624 [XXX] my vehicle no longer drives or shifts out of park, "Not able to charge" message displayed, CEL light on. A class action lawsuit revealed a technical service bulletin 18-NA-261 released in 2018 (see attached) accusing GM of continuing support of the known faulty module. The result of the case was Special Coverage Bulletin N232432680 which acknowledges and addresses the above mentioned issues by replacing a faulty BECM common to ALL Chevy Volt models years 2016-2018. My VIN is EXCLUDED from coverage due to being a CARB compliant vehicle despite exhibiting the same behaviors, error codes, and sharing the same faulty BECM. Of the 60,000 Volts sold in 2016-2018, only 19,000 (~33%) qualify under the special coverage terms. 100% of the vehicles that qualify for coverage are NON-CARB compliant.

Vehicle had the Battery Energy Control Module fail at about 87,000 miles. Vehicle will not start and will leave you stranded when this happens. This is a known defect and GM issued a special coverage to extend the warranty for this specific component, but for some reason only applies to a handful of VINs. Mine was not one of them, so I got stuck with a $2500 repair bill. I love the car and am not mad that they are breaking, engineering is hard. I am mad that even after a requirement from the NHTSA, Chevy is refusing to repair a known defect with their vehicles that can leave the owner stranded and is making the owners foot the several thousand-dollar repair bill. This was my first Chevy, and due to the poor way this has been handled, probably my last.

My experience is proof for the investigation on “loss of motive power, including a stall, reduced power state, and/or a no-start condition due to the Battery Energy Control Module (BECM).” My safety and the safety of others were affected because the reduced engine propulsion caused me to drive at a max speed of around 50 mph, and eventually the car left my stranded a few weeks later when it would not start at all in a parking lot. The gas engine would run at an extremely high RPM to make up for the failure of battery propulsion. The dealer covered the work under warranty. The work was performed during the pandemic chip shortage in 2022 and my car was at the dealership for two months from about August to October. The check engine light would come on sporadically before the problem started, and when the failure would occur, I would get a “Propulsion reduced” message in the driver screen and the gas engine would kick on to an extremely high RPM even when the car should have been running on battery. Accelerating from a stop to a normal speed would sound like you are flooring down the accelerator to get on a highway on-ramp. I no longer have the paperwork to confirm this, but it was performed at the Fort Collins (Colorado) Dellenbach Chevrolet dealer, it may be possible for me to get the paperwork, but I no longer live in Colorado. The process went all the way up to corporate Chevrolet before the warranty was honored, and I was compensated with company points.

My 2016 Chevrolet Volt loses power while driving and the "propulsion power reduced" warning message appears. This has happened multiple times in the past few weeks and it is very dangerous losing power while traveling. After taking it to a Chevy dealer for service, they advised that it was an internal failure of the BECM (battery energy control module) and that it would need replaced. After searching online it appears that this is a common issue with the Chevy Volt models from 2016 - 2019. So much so that GM extended a special warranty to cover this failure up to 15yrs and 150,000 miles. Unfortunately for reasons I still don't understand, I was informed that my vehicle is not covered under this special warranty despite it specifically being the year and model that is affected. My vehicle currently has 93k miles and was purchased in 2016. So I am just outside the original 8 year 100k mile warranty but thought I was covered under this new special coverage given that this is an issue that GM is clearly aware of. I was also shocked to find out that there apparently was never a recall for this issue. My wife and child normally take this vehicle across town at highway speeds and I'm lucky the issue only happened to me. I fear for those who brought their vehicles and are not aware of the issue and will be told that theirs isn't covered as well.

Took the car in for service to Simi Valley Chevrolet on 8/16/2023 due to the check engine light illuminated on dashboard. They determined that the EGR valve had internally shorted so they unplugged it so as not to take down the rest of the system and placed a special order for the valve. It has now been over one year and they still don't have the replacement part. The car runs rough and occasionally stalls and sputters. I'm concerned that the car could stall while driving and is unsafe.

Driving to work one morning, I noticed an engine light with a "Propulsion Power Reduced" on my 2016 Chevy Volt. Upon closer arrival to work, the car was behaving quite erratically with constant "Propulsion Power Reduced" errors on the dash. The A/C stopped blowing cold and immediately fogged up the front window, making me unable to see the road. After arriving at work, I could smell what could be described as a burning electrical smell coming from the vehicle, although no fires were seen. Upon checking diagnostic codes, the car had a list of codes pointing to the failure of the Battery Energy Control Module (BECM.) I researched the issue and discovered "N232432680 - Special Coverage Battery Energy Control Module Malfunction" listed by GM and the NHTSA. My Chevy Volt is within the model years (2016-18) and mileage (<150,000) for the special coverage warranty from March 2024. Upon checking with the local GM dealer, they said that my VIN is not included in the special coverage and I must pay out of pocket, even though I have the exact problem described in the warranty and my Volt satisfies other conditions (model year and mileage). I am scheduling a service appointment this week with the local dealer to formally diagnose and repair the issue.

The car has experienced a ‘BECM’ failure, which is very common on the Chevy volt. When it fails the car becomes undrivable and will slow down into reduced propulsion mode. It will not start and required us to have it towed to the dealer. The 2016-2019 Chevy volt BECM issue has been investigated by the nhtsa and gm. It is a common enough issue that gm has voluntarily issued ‘special coverage N232432680’. This covers the becm failure on 2016-2019 volts for free for up to 150k miles 10 years. We have a 2016 volt with 144k miles so we assumed it would be covered. The dealer said it wasn’t covered based on my vin but they didn’t know why our vin was left out of the coverage. Obviously if they thought our car didn’t have a suspect becm, they were wrong because it failed during the special coverage time. The repair is $2600 and gm will not assist us with this repair. I have attached a copy of gm special coverage and the bill. This seems to be a clerical error that our vin and maybe others were missed despite the fact our car falls right in the special coverage criteria. I believe this should be a full recall or 2016-2019 volts, especially if the becm has failed.

The EGR valve in the 2016 Chevy volt will fail blowing fuse 3 which will also take out the engine oil pressure control solenoid, the evap emission purge solenoid valve, the engine coolant thermostat heater, and the oxygen sensor 1 as they all share the same fuse. The car will tell you that the engine is unavailable and, if you are out of hybrid battery power, will leave you unable to move the vehicle. In my particular situation it left me stranded blocking one lane on a two lane s-bend road on a 5-9% grade mountainside with no cellphone reception. Thankfully the car stopped far enough away from the previous bend that people had time to see me and I didn't get rear-ended. If I had stopped 20 feet sooner that likely would not have been the case. The replacement part for the EGR valve is impossible to find as it is back ordered everywhere and places that will let you back order it will try to charge $1927 just for the part (no installation service included). If you live in a state without emission checks then you can unplug the EGR valve and replace the fuse but that means your producing more pollutants. Until GM gets their act together and offers affordable replacement parts I don't see another alternative.
