2016 CHEVROLET VOLT Complaints

The Battery Energy Control Module (BECM) on my 2016 Chevrolet Volt has failed. The vehicle and the component are currently located at my home address and are available for inspection upon request. As of writing this now. This failure caused the vehicle to enter a "reduced power mode" and subsequently resulted in a no-start and no-charge condition. The sudden loss of propulsion power presents a severe safety and crash risk, as the vehicle can lose motive power and stall unexpectedly while in transit. Prior to the complete failure, the vehicle displayed a Check Engine Light and a "Reduced Propulsion Power" message on the dashboard. The local Chevrolet dealership has inspected the vehicle, pulled the associated diagnostic trouble codes, and officially confirmed that the BECM has failed. General Motors has already acknowledged this specific safety defect through Special Coverage Bulletin N232432680, which extends BECM warranty coverage to 15 years or 150,000 miles to prevent sudden loss of propulsion. However, GM corporate and the dealership are refusing to honor this bulletin. They are denying coverage due to an administrative database flaw because my vehicle's under-hood VECI label designates it as an original California (CARB/PZEV) vehicle, GM's system excluded my VIN from the Special Coverage bulletin automation. Furthermore, because the vehicle is currently registered in a non-CARB state (Texas), the original CARB warranty is considered void. GM is using this internal database loophole to deny repairing a documented safety defect.

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)

My 2016 Chevy Volt started experiencing the "Propulsion Power is Reduced" issues associated with a faulty BCEM unit. I brought my vehicle in for service at a Chevy dealer and they confirmed that the BCEM needed to be replaced. This is a known issue resulting in special coverage under N232432680. Chevy is not honoring the special coverage for my vehicle despite my vehicle being less that 15 years old and having fewer than 150,000 miles. According to the service manager after talking to someone higher up the food chain at Chevy, "they're no longer covering this service."

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.

Vehicle displayed reduced propulsion and shift to park while driving on highway then suddenly stopped. Dealer said battery failed after a year of diagnosing issue. Issue may be BECM which has extended warranty service but dealer not addressing the issue of car stalling but instead other costly minor issues leaving the vehicle a safety concern. Replacing battery with a bad BECM would lead to exact same issue

After experiencing loss of power and loss of propulsion on the highway, took the car to Tropical Chevrolet in Miami Shores, FL. after diagnosing the car for $287.37 (credited to the estimate total of $3101.20), the dealership replaced the Battery Energy Control Module and bled the battery pack cooling system. We paid the bill ($2665.89). On January 4, 2026 the check engine light came on again when the propulsion was reduced again, while driving on a highway. Tropical reported that the cause of the failure was their failure to replace or do the original repair at all. They replaced the exhaust gas recirculation valve and refilled the cooling system. The parts should be covered by warranty. We filed a claim with GM 2 months ago and still have not been reimbursed.

The engine light came on, but the car would run and so took it to the dealer. They determined that the EGR valve had failed and would cost $2400 to repair. Apparently, this is a common failure point for Generation 2 Chevy Volts. If it might trigger a forced recall, I'd like to add this to the list.

In May 2025, the EGR (Exhaust Gas Recirculation) valve failed on my 2016 Chevy Volt with approx. 60,000 kms / 40,000 miles on it - that cost me approximately $3,000 to fix. In my opinion that should have been covered under warranty given that it is a common failure point on second generation Volts. Note that the EGR value (OEM - Original Equipment Manufacturer) is a readily available part. In October 2025, my BECM (Battery Energy Control Module) failed. Luckily, due to significant Volt owner complaints, GM was forced to provide a special warranty on this item, so the work that would have cost me approximately $4,000 was covered under this special warranty. The BECM is covered for my 2016 Chevy Volt until 2030. Note again that the BECM is a readily available OEM part. In December 2025 my Chevy Volt check engine light went on again, and this time the Chevy Dealership is telling me that the main hybrid battery needs to be replaced. However, GM decided in their infinite wisdom to discontinue production of the Chevy Volt battery, and so they can't even sell me a new hybrid battery, a critical component on this vehicle. My understanding is that the 2016-2019 Chevy Volt battery is the same part #24060122. The Chevy dealership has asked me to see if I can find a battery on my own, as their parts department cannot source one (GM used "York Electronics" in Canada). As a result, I am now left with trying to find a used/refurbished hybrid battery. If my Volt was a 2019 (the last year GM made the Volt), then this battery would be covered under warranty (8 years from in service date), yet GM wouldn't even be able to fix a 2018 or a 2019 Chevy Volt because they stopped making the battery for ALL Volts. How can a manufacturer get away with not even providing parts for 10 years (in my case), or 7 years (2019 Volt)? My only option seems to be to send a perfectly maintained car to the junkyard at 60,000 kms/40,000 miles. Never again will I buy GM.

GM is not honoring coverage from N232432680 for CARB vehicles in non-CARB states. They have failed to tie CARB vehicle vins to the coverage in N232432680.

This vehicle has had multiple incidents of surging of the propulsion system both on battery power and when powered by the internal combustion engine, causing loss of propulsion and sudden acceleration almost causing collisions multiple times. We have paid for over $4,000 in repairs that are not covered under the propulsion system warranty, and these repairs have not remedied the issue.
