On [XXX] while driving with my son in IN on [XXX] to my niece's wedding in PA, a reduced power warning sounded on the driver's console. Was able to stop and get gas at the eastbound travel plaza near mile marker [XXX]. Getting back on the road and accelerating toward 70 mph, suddenly lost all drive power. The fuel gauge side of the console was lit in yellow and said something like "No fuel detected." Pulled over to the shoulder and found the engine would start, run, and then die. An IN State Police Officer was kind enough to offer us an escort to the next exit near mile marker [XXX]. Noticed that the engine would remain running for longer periods and finally stayed on continuously. While being escorted, was able to run the speed up to 55 mph and made it safely to the interstate exit. During this time my son was checking online and found that the problem might be due a blown fuse. At the [XXX] exit we found a Pilot station that carried fuse sets. One of the sets had the fuse we needed. We bought two sets. We replaced the fuse--it had blown--and the car ran well again. This fuse is called "No walk home." We were able to continue on at 70 mph until stopping at a friends home in western PA for a few hours rest. While at our friend's home we partially charged the Volt's battery giving us about 20 miles of electric range. While in electric mode we stopped for gas. We drove through the mountains without incident then stopped for gas again in central PA at the Cumberland Valley Service Plaza. Filled the tank and while accelerating from the plaza again lost power and had to pull over. Replacing the fuse solved the problem once more. It appeared that turning off the engine while in gas mode and then turning the engine back on leads to the fuse blowing. That Sunday on the return trip to IL, I never turned the car off when refueling. This got me back home without incident.

Chevy Volts from 2016 - 2019 all have a manufacturing defect which can prevent the driver from powering - the error message is "Shift to Park". GM released a Volt Service Bulletin in May 2021 but offered no assistance to replace the defective part. On [XXX] I was driving home on [XXX] headed [XXX] from Santa Cruz in fair weather in the afternoon. This highway can be dangerous with limited shoulders and poor visibility, making it an unsafe place to pull over. While traveling at about 55 mph, the car made an alert sound and illuminated the check engine light and presented a message "Shift to Park". I was running out of room on the shoulder to pull off safely so I had to make the quick decision to pull off to the left-hand shoulder. I followed the instructions on the display which said to shift into park, followed by shifting back into drive. During this time I had my foot on the brake, but after removing my foot from the break, the vehicle began to roll towards traffic, so I put my foot back on the break. I tried powering the car off/on multiple times and tried to get the car to go back into drive but was unsuccessful. Eventually, I put the car back into park, called a tow truck driver, and waited for over an hour to have my car safely towed off [XXX]. Prior to this, I had not experienced any of these or similar symptoms. An OBD code scan was done (screenshot attached). Once at the Chevy dealership, they confirmed that the car could, at that time, shift into park and were not able to reproduce the "Shift into Park" issue. However, they reported that the car was revving high and the transmission would not shift into the proper gear ratio. The dealership was not able to fully diagnose the problem and instead suggested to replace the entire transmission as assembly and then continue investigating. We reached out to the manufacturer, Chevrolet/GM, about the issue(s) and were ed case # [XXX] while they work with the dealership to investigate further.

My 2018 Chevy Volt has experienced the GM knows BECM issue. There are several Volt Owners that have experienced this issue. I would like to bring this to the attention for GM to post a recall/mandatory service repair as my car stopped working, would not start, was displaying false information on the electrical module, etc. Issue: 1. Car would not start 2. Battery stated fully charged with solid green light but display showed only 1 electric mile available 3. Tried to shift car to Reverse press gas nothing happened 4. Tried to shift car to Drive press gas nothing happened. 5. Car engine light is on 6. Utter confusion as stress as I-??m stranded with no way to get my car working 7. Chevy dealership has had my car for one week now with the only update of ordered BECM module. No ETA on when this will be fixed 8. No indication of what caused the issue

After recent repair of hybrid transmission, experienced a loss of power, MIL, and several trouble codes related to the battery control module (BECM). This affects safety as the loss of propulsion unexpectedly causes deviations in speed from typical traffic flow. The problem was confirmed by OnStar and a manufacturer representative was advised with a dealer appointment scheduled when they next open. There were no lamps or other symptoms prior to this MIL and loss of power. Restarts after shut down have not been attempted until able to take the vehicle to the dealership.

My 2018 Chevy Volt was at a Chevrolet dealership in Burbank and they have been running tests on my car to re-create the problem which they have not been able to do. On [XXX] my car suddenly stopped and shakes violently after I turned it on after about driving 15 feet, and my screen was telling me -??engine not available, service needed soon-?? so I got it towed to the dealership (no prior warning signs on dash or anything). On [XXX] they told me they were not able to find the fix or recreate it and also said -??This is definitely very rare. Drive it around and bring it back in if it happens again-?? which felt like they really didn-??t care for my safety at all. On [XXX], the same exact problem happened with my car, -??engine not available, service needed soon-?? and shook violently (my girlfriend witnessed it) after 100 yards of driving it and then towed my car back to the dealership. On [XXX], 23 DAYS LATER, the Chevy dealership calls to tell me they still haven-??t been able to recreate the problem or find a solution again. I haven-??t been able to drive my car this whole time. I have had a case open with GM this whole time where they have been extremely spotty on communication and pretty much just ignoring me the alot of the time. They called me on Saturday, [XXX] (when they-??re -??closed-??) to tell me their solution but I missed the call, I called Monday and Tuesday but can-??t get in contact with my advisor until finally Wednesday, I call and they are able to connect me and they gave me a final solution on [XXX] of $1500 off a New GM brand car so they weren-??t in any rush to contact me about the final solution. They should repurchase the car from me and pay for damages. Car feels extremely unsafe and there should at least be some type of diagnosis-?? CHEVROLET CANT FIX THEIR OWN CARS, UNREAL!!!!

My BECM failed pulling in to my grandpas house. I was able to park the car, but unable to start it afterwords. Prior to failure, the engine would switch between electric, then back to gas, then back to electric This is a very common issue on these vehicles.

Chevy Volt lost power while driving on the highway. No warning. The car has been at the dealership for 3.5 months and they have yet to tell me what the issue is, I have asked every time. Seems as though they don't want me to know. HIghly likely it is is BECM issue. Also, I scheduled the car to be looked at via their app, the day I arrived for the appointment no technician was available, and said I needed to reschedule and bring it back in a week. I just left the car there because it was incredibly unsafe.

Vehicle is 2018 Chevrolet volt with approx 91000 miles, purchased new in California with both PZEV and Voltec warranties in place. Vehicle produced MIL in December, in Colorado, with exterior temperatures ~30 degrees, after attempting to remote start. The resulting OnStar Codes P1AEE, P1AEF, and P0AC4 indicating "the electric propulsion system is not performing as expected. Please service immediately." Drove the vehicle to the nearest dealership assuming there could be an unexpected loss of power. Identified PIC6285B as trouble shooting aid for the dealership. The dealership stated they contacted their GM TAC representative and the service foreman and TAC agreed the vehicle needed a transmission flush. No indication that the work would be covered by the bulletin found. Customer contacted Chevrolet EV advisor and confirmed vehicle did not qualify for any warranty as the diagnostics indicated a category 4 issue associated with the bulletin but the repairs required were a transmission flush. This was contrary to the published bulletin, other customer reports, as well as the specific DTCs expected. Customer believes diagnostics would be covered by bulletin or warranty given a repair was identified based on the trouble codes that were pulled. Dealership and GM did not agree with customers belief. Customer forced to pay in order to recover vehicle after 1 week.

The Battery Energy Control Module needs to be replaced (BECM). The car is available to be inspected at Key Chevrolet in South Burlington, VT. The car was parked when it failed. The car wouldn't start (lights on the dashboard came on) and it wouldn't turn off. I got a "shift to park" error message, regardless of which gear I was in. The car wouldn't go into Drive to go forward with either the drive battery or the gas generator. I had the car was towed to the dealership. It was inspected and diagnosed by them. When they did the diagnosis, they said the BECM had failed and there were cells in the drive battery that needed to be replaced. The BECM failure is a common problem with Chevrolet Volts and is covered by the Voltec warranty. There were no warning lights or other warnings (e.g., reduced propulsion) whatsoever. The car had shut off like normal but would not start or turn completely off. I was fortunate to have had the BECM fail while the car was parked. My understanding is that BECMs can fail while the car is moving and the power will stop and you won't have any control.

My 2018 Cheverolet Volt stopped charging via the PHEV port, the check engine light came on, and "Propulsion Power Is Reduced" read on the driver display. Car acceleration began to lag and I called the dealership service department immediately. I took it to the service dept and they said the repair is under warranty but the part is back-ordered with no ETA on when I will get my car back, but I should keep it there to prevent from getting stranded. They will provide no loaner car. It is currently at the dealership and I have no transportation. This appears to be a BECM issue.

The vehicle failed to restart after being parked in a garage all day while at work. On board diagnostics returned multiple codes concerning the EV battery and vehicle integrated control module. Specific descriptions include: The Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicles battery pack charge level; Vehicle network communication code. The network provides a communications link between systems inside the vehicle and when the network is disrupted a code can be set. If vehicle functionality is impacted please seek service soon. Dealership indicates the Battery Module needs replacing and part is back-ordered with unknown delivery time. There had been no warning or other diagnostic codes visible prior to the failure.

While Driving my 2018 Chevy Volt from Payson Utah to Provo Utah going north on the I-15 Freeway the car Lost Power and came to a stop. Luckily I was in the outside lane and was able to coast to a stop on the shoulder and wait for a tow truck to take the car to the nearest dealer in Spanish Fork Utah. My safety could have been seriously affected if I had remained stalled on the freeway. The car would no longer start or Turn off. The display only showed that the car should be shifted to park even though I had already completed that request. The car has been inspected by the Dealer for GM. No one else that I know of has inspected the car. No Previous warnings or messages appeared before the incident occured.. The Dealer is Telling me the car-??s battery energy control module needs to be replaced and that it could take months to get a part. This is way to long for a car to wait to get repaired if the manufacturer claims to still be making the part.

A Shift to Park message displayed while the vehicle is in park. The car will not turn off and continues to run. The issue is well documented through GM/Chevrolet, as they have a service bulletin (19-NA-206) for it. That document specifically states that the Voltec Warranty covers this issue, but Chevrolet is refusing to service my car based on its VIN number, despite identifying it as the same issue. And for the last question, no lights initially came on but then the check engine light came back on. When the car was finally turned off at the dealership, it turned back on with no issue lights or messages.
