2016 Chevrolet Volt transmission problems

Filed Mar 20, 2026 · Electrical, Transmission · UT

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 the federal safety agency, and GM only issues orders by VIN, and therefore cannot cover the issue. After calling the federal safety agency, 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.

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 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 federal safety agency, 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.

The contact owns a 2016 Chevrolet Volt. The contact stated that while starting and driving at an undisclosed speed, the "Reduced Propulsion" message was displayed. Additionally, after parking the vehicle, the "Shift To Park" message was displayed, and the vehicle failed to turn off. The contact pressed the Start/Stop button and then opened and closed the front driver's side door to turn off the vehicle. The vehicle later failed to charge and start as needed. The vehicle was towed to the dealer, where it was determined that the Battery Energy Control Module (BECM) needed to be replaced; however, the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 83,574. The VIN was unavailable.

Faulty micro-switch from factory, causes power surge. Flawed microswitch in transaxle shift cable. Incomplete connection of microswitch resulting higher voltage to PCM.(power control module) This irregularity, shows a DTC code reducing power propulsion during movement. The car will loose power & ability to shift. During driving movement. Quite a safety concern. A "shift to park" error displays on driver display screen. An OBD2 scanner will clear code & after a few attempts remain operational. However intermittent & unpredictable when to expect the loss of traction power.

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.

The vehicle loses power when trying to accelerate when driving in electric mode, and the gas engine kicks on after a second at which point acceleration returns. It occurs when the battery power is high or low. Sometimes a warning pops up on the dash saying speed is limited to a specific MPH.

I was driving in clear weather (with my ICE engine as propulsion) when an Engine Warning Fault light appeared on my dash and the vehicle slowed to 5mph with no response from the throttle pedal. I pulled into a parking lot, had the vehicle towed to an independent service shop, and had them check the codes. There were a dozen faults stored, but they found the 'Non Walk Home' fuse had blown, and faults pointed to the EGR Valve as having faulty electronics. They could not find an EGR valve for sale so they unplugged the EGR Valve and replaced the fuse, which allowed the engine to drive normally again, but with the Check Engine Light on at all times. I called my local Chevy dealer and they told me the EGR I needed was Part Number 12691147 for $243, but they were backordered and there were dozens of people in front of me for their dealer alone. Now, 11 months later, I'm still waiting on the part, I have found hundreds of other Volt owners online with the same issue, and the Part Number has been changed by GM to 19436113, with a price increase of 1100% to $2642. And the part is still not available because of "high demand" on a car that was discontinued five years ago.

On [XXX], this Volt was towed to the Dealer because the Volt would not start, would not charge, and the engine light was on. The Dealer claimed that the problem was the Chevrolet Volt Battery Energy Control Module (BECM), GM Part # 24296900, which was covered under the GM hybrid VOLTEC warranty (8 years, 100,000 miles). On [XXX], 2024, this Volt (VIN [XXX] ) was towed to the Dealer again because the Volt would not start, would not charge, and the engine light was on. The Dealer claimed that the hybrid battery connectors were corroded, the disconnect relay should be replaced, and the BECM should be replaced again at a total cost of $5,005.58. On [XXX], GM issued special coverage warranty N232432680 (15 year, 150,000 miles) to cover BECM replacements for a malfunction involving the BECM. Plaintiff checked the VIN at the GM Recall and Warranty Center website. The Volt at issue is covered under special coverage warranty N232432680, according to the GM website.
