  Initially was receiving intermittent “Recieved Propulsion Power” warning and no check engine light. Did it about every 2 weeks but became worse. Received Reduced Propulsion power warning on a road trip from East TN to Charlotte then showed a check engine light. I continued to Charlotte I had 4 miles left on battery and was running on gas engine when “Engine Not Available” warning came on leaving me with a nearly dead battery for propulsion. Fortunately, there was a very nearby GM dealership in Charlotte which I was able to drop off and flew out of town for the week. I was told by the dealership that it was an O2 sensor and they had replaced it. Picked up the car the next week. I began the 3 hour trip back to East TN and about 30 miles into the trip I received the Reduced Propulsion Power AND Engine Not Available. I had about 10 miles left on the battery so I stopped and stayed at a hotel with a car charger overnight. Resumed trip home that am, but same code was displayed and engine would not come on. Rented a uhaul w/trailer and towed it home. Dropped it off at Champion Chevrolet in Johnson City and they diagnosed it as a faulty EGR valve. I learned that the part has been back ordered and looking at web forums I see people have described the same problem and they have been waiting many months for an EGR to be available. So, nature of complaint is: I got lucky in that I did not get stranded. Fortunately I was in the right place at the right time. I could have easily totally lost propulsion were my battery were fail and don’t know if I could have gotten off the roadway.

  When attempting to turn the vehicle off after parking, the driver's console displayed the message "Action required: Shift to Parlk". The shifter was already firmly in the "Park" position. Moving the shifter back to "D" and then back to "P" did not resolve the issue. Pressing the power button twice more resolved the issue this time without further moving the shifter. This is a well-known and well-documented issue with "Gen 2" Chevy Volts.

  When trying to turn off car while shifter is in park, Car state “shift to park”. Dealer supposedly fixed it last year, but the issue is still occurring.

• 12/22/2025· POWER TRAIN

  My 2018 Chevrolet Volt frequently fails to recognize when the vehicle is shifted into Park. The dashboard displays “Shift to Park” even though the gear selector is already in Park. When this occurs, the vehicle will not power off, requiring multiple attempts to move the shifter before shutdown is possible. This creates a safety risk because the vehicle may be left powered on unintentionally and may not properly secure itself in Park. In one occasion, the vehicle moved backwards even when shifter was in Park, which created a collision risk. This is a known defect affecting many GM vehicles, including the Chevrolet Volt, and has been widely reported by owners. I am concerned about unintended vehicle movement, battery drain, and driver safety.

  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.

  On Dec 3, 2023 I got the message "Propulsion Power is Reduced" and the gas engine started even though there was about 53 miles left in the battery. I was able to continue on to my destination use the gas engine. On Dec 8, 2023 I drove the car to La Quinta Chevrolet and they diagnosed the problem as a failed BECM (Battery Energy Control Module). On Dec 11 I got the car back and was told the BECM is on backorder and there is no estimated delivery date. Also on 12/3 when I tried to start the car after getting it home I started getting the message "Shift to Park" The dealer was able to fix this before I got it back on 12/11. I've been told I don't qualify for a loaner vehicle so I am left with a car that could stop at any time.

• 12/19/2024· ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM

  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.

  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.

  On June 27, 2025, while driving, the vehicle displayed a "Propulsion Power Reduced" warning message and a Check Engine Light illuminated. I immediately experienced a loss of power. I brought the vehicle to an authorized Chevrolet dealer the same day. On July 1, 2025, the dealer diagnosed the failure as a faulty Battery Energy Control Module (BECM) and high-voltage system fault (Code P1E00), requiring a full replacement of the high-voltage battery pack (Part #24296900). The manufacturer (GM) was contacted, and the replacement battery was ordered on July 2, 2025. As of December 2025, the vehicle remains in dealer possession (over 5 months) with no repair completed. The manufacturer has stated the part is on indefinite backorder with no ETA. The failure of this component renders the vehicle inoperable and presents a safety risk due to sudden loss of propulsion power while in motion. The manufacturer has confirmed the failure but is unable to provide a remedy within a reasonable timeframe.

• 12/09/2023· POWER TRAIN,VISIBILITY/WIPER

  In August 2023, while driving on I-93 in Boston, car switched from Battery Mode to Engine Mode, and Driver Information Screen reported "Reduced Propulsion". Propulsion Battery charge and gasoline fuel levels were adequate such that this should not have happened. In this Reduced Propulsion state the environmental systems, i.e. Heat/Defrost/AC, become inoperative. A thunder storm overhead was pouring cold rainwater on the windshield and it became fogged inside from condensation. Because windshield Defrost was not functioning my passenger and I had no recourse but to frantically grab whatever we could to wipe away the condensation and keep some small amount of road visibility. This problem is intermittent. Car is available for inspection upon request. Reduced visibility in a moving vehicle is a safety hazard to the driver and all those in their vicinity. A dealer or service center has not been alerted. The vehicle has not been inspected for this problem. The intermittent problem of vehicle entering "Reduced Propulsion" Mode first occurred in July of 2023. I have an On Board Diagnostic (OBD) reader that always reports Diagnostic Trouble Code (DTC) P1E00 when the problem occurs.

  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.

  On 8/3/ 2023, my 2018 Chevrolet Volt lost propulsion power while I was camping in the Lassen National Forest near Susanville, CA. I was leaving my campsite when I was on the way to Bend, OR when the car lost power and went into limp mode. It was a two lane road on CA 36 without a shoulder, so I was stuck on a travel lane. I was able to turn the car off and on for a few seconds where I would reach a maximum speed of about 15 mph for about 5-10 seconds before the car would go into limp mode again. I did this for about 20 to 30 times until I reached an incline and the car did not have enough power to inch up the hill, so I had to push the car down the travel lane to the nearest open space I could find that would not block the travel lane. After walking two miles to get cell phone reception, I was able to contact AAA where then towed my vehicle two hours south to the nearest Chevrolet dealership in Reno, NV (Champion Chevrolet). I had to rent a car to continue my trip and eventually get back home. On 8/21/2023, I was contacted by Champion Chevrolet and was told that the issue was the issue was the Battery Energy Control Module (BECM) and that was going to be covered under warranty. However, they noted that the BECM was on national backorder and that there was no ETA for when they would receive the part. Because of this, I had to extend my rental for the month at a cost of about $1,800 to be able to get home to Los Angeles. As I write this on 12/1/2023, I have still not received my vehicle from the dealership and the part is still not available. I've now lost almost 4 months of use of my car and still make payments on it, after I purchased it at lease end. The car had about 55,000 miles on the odometer when the car stopped working and the BECM issue was discovered. The status on the part for my car is still backordered with no ETA. After reading GMs claims they have sufficient replacements in supply, I write this complaint to call their bluff, as no parts are available.

  Although the battery showed fully charged, the vehicle was not using battery power. At various points I would receive a "propulsion power reduced warning" and the car would lose power. I was driving on 2-lane windy country roads with no passing zones and lots of hills. At one particularly steep hill, I received the warning light and the car started lowing power again. By the time I reached the crest, the car had nearly come to a complete standstill. I have no doubt had I not reached it at that point, the car would have lost all power and begun rolling backward. The speed limit on this road is 55mph with several blind curves and hills, so the potential for a serious collision was great had it begun to roll back. When I reached my destination and turned off the car and restarted it again, it would only shift to neutral. It is now at the dealership where it was diagnosed as needing the BECM replaced.

  To begin, I will set the scene of my experience. I was traveling east bound on 84 in northeast PA on my way to Long Island for work meetings that day. I was about one hour and a half away from my home at roughly 6am. I was traveling at apx. 70 mph when my car suddenly says "engine unavailable, reduced propulsion." and the fueld tank turned yellow in color on my dashboard. Then a sign said "service soon." My car then COMPLETELY STOPPED WORKING. My speed fell from 75 mph or so to 0 in a matter of a minute, I had no idea what was happening because there were no appropriate warnings such as, "Pull over immediately" or "SAFETY CONCERN PLEASE GET OFF THE HIGHWAY" -I would have taken anything to know that this was an actual emergency and I needed to at least get to a shoulder. I luckily was able to come to a stop mostly off the highway in a shoulder. I was located around a bend, in the pitch black, unable to stay in my car out of fear I would be smashed by a tractor trailer or car that did not see my car suddenly stopped. The car would not go in neutral or anything other than park and I left the hazards on (they eventually failed). I called my husband who drove to me while I stood on the side of the highway for an hour and a half in 30 degree weather. I called the police who were eventually able to put up flares and mark me as a hazard on the road. If there was a car traveling behind me, I would have been killed or seriously injured because I slowed so suddenly and had no way of knowing that this was an absolute emergency. The worst part is that this is the second BECM failure in my volt and I have driven less than 1000miles since it was repaired the first time (which took >5 months). The first time this happened my car was on a quiet town road and my brother who was driving just parked and had it towed. He hadn't thought there were any warnings but he wasn't sure. This time, I could have been smashed on the hwy with little to no warning. I can't believe Im alive.

NOW I HAVE A VOLT AT THE BODY SHOP FOR THE 5TH WEEK (LACKING AN AC LINE FOR REASSEMBLY), AN OVER 55% INCREASE IN MY INSURANCE PREMIUMS (PER THE RENEWAL NOTICE I JUST RECEIVED) AND WHAT REALLY HASN'T BEEN A GOOD EXPERIENCE. WHILE I'M WAITING FOR THE RETURN OF MY VOLT I HAVE RECEIVED THE IMPORTANT SAFETY RECALL INDICATING THE BRAKING PERFORMANCE MAY BE REDUCED. IF THE CAR HAD BEEN ABLE TO STOP TWO FEET SHORTER I'D HAVE AN UNDAMAGED THREE MONTH OLD VOLT AND MY INSURANCE STANDINGS UNTARNISHED. THAT TWO FEET ENDED UP COSTING OVER $17,500 TO THE CAR. TURNS OUT VOLTS ARE ALSO EXPENSIVE TO REPAIR. I'M A 55 YEAR OLD MALE, NO WILD KID. STILL STUNS ME THAT IN 2018 GM CAN'T GET BRAKES RIGHT...THE MOST IMPORTANT OF SAFETY SYSTEMS.

  Chevy had done an update for the Propulsion Power being reduced. In 2024, I had to do another update when the check engine light came on. After that the electric battery power decreased, I am only getting 17 miles per charge. August 2025, the check engine light came on again. I had it check and no codes came up. While driving home on the freeway, the Propulsion Power being reduced warning came up. I had to pull off the freeway. Once I turned my vehicle off, I was unable to drive my car. There was not any acceleration. I had to have my car towed 50 miles home. A mechanic was able to repair it at that time. On 10/7/2025 the check engine light came on again and once again no codes appeared, on 10/14/25 the Propulsion Power being reduced warning came on again. I was able to get home safely, but I got off the freeway and took side streets home. At this time, the vehicle will not accelerate.
