When putting my car in park and shutting it off the dash board tells me to shift to park, and car does not fully shut off.

- Belleview, FL, USA

Driving on gas on the highway, the adaptive cruise control suddenly disabled with a "Reduced Propulsion" message on the dash and a check engine light. The car started struggling in its propulsion. We found an AutoZone and scanned the codes, and multiple were returned. A Google search pointed us to the "walk home" fuse, which indeed had been blown. Replacing that fuse and disconnecting/reconnecting the battery eliminated the errors. Less than a week later during highway driving (the next time the battery charge was used up and it switched to the ICE) I got another check engine light, but this time without the "reduced propulsion" message. Scanning at AutoZone again revealed a P0404 message referencing the EGR valve. Due to the limited availability of the part I have called into Covert Bastrop (Bastrop, TX) and am waiting to hear back on their ability to fix the car.

The issue started with a forward push while lowering my speed while coming to a stop. It then progressed to a trembling engine. Then it progressed to the car struggling to effectively switch from electric to gas and back. It then would only be usable on electric range and the engine would not start and would be greyed out. Now, it only works on engine mode, it uses fuel like a pick up truck, it loses power while driving due to trying to switch to electric mode and back, and it struggles to accelerate. It will do it while idle as well as while driving 45mph and up. It barely has any propulsion power and I have to turn my hazards on any time I am going to accelerate. If I brake hard the engine will shake violently and then shut off. I then have to switch gears from drive to park or neutral to park to drive to reengage the engine. Recently it has turned on all the accessories but the ev and the gas is greyed out and there is zero propulsion power. I replaced the 12v battery thinking it might have been dying and it still has the same issue. I read about the class action lawsuit for the BCEM and have made an appointment the dealership but when I told them what was wrong with it the said we need to wait for the diagnostics.

Due to the failure, the vehicle was towed to an independent mechanic where it was discovered that the BECM (Battery Engine Control Module) was defective. The mechanic discovered that the vehicle was under warranty and contacted that the local dealer for assistance. The mechanic drove the vehicle to the dealer who acknowledged the failure; however, the dealer stated that the failure was not covered under warranty. The manufacturer was also notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 100,000.

On [XXX], while driving on [XXX] in Virginia, the check engine light came on in my Chevy Volt. A message on dash said that there was reduced propulsion, and the gas engine quit running. The car switched to battery power, which would not have lasted long enough to get us home. At this point, we were stranded on a very busy highway which seemed quite dangerous. Using battery power, we were able to get off the highway. We then made arrangements to have the car towed, approximately 150 miles to a car dealer/repair business in Frederick MD. The vehicle was checked out by the car dealer who identified the EGR valve as the problem. However, they did not know when the part would be available, and still, 4 weeks later, do not have any date for availability of the broken part.

While driving our 2018 Chevy Volt, dashboard warning message -??Propulsion Power Reduced-?? displayed. Vehicle performance was not otherwise affected. Subsequent diagnosis from our Chevy Dealer was, among other things, a faulty Exhaust Gas Recirculation (EGR) valve. We were informed that our vehicle was -??no longer safe to drive in this condition-?? and the vehicle has been sitting on the Dealer-??s lot awaiting a replacement part for 2 months and counting, with no expectation of near-term resolution of our problem. We are aware that this is a widespread problem on 2017-18 Volt models, with many dissatisfied owners.

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.

- Irvine, CA, USA

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.

After getting some repeated "propulsion power is reduced" display warnings, my 2018 Chevrolet Volt literally died without warning while I was driving it on New Year's Eve and could not be restarted.

- Lakewood, CA, USA

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.
