Shift to park issue. Known issue with 2018 Volts but dealer is charging diagnostic fee when they know it is the issue because it displays shift to park when you try to shut car off. There is a bulletin stating this 19-NA-206. It states the Voltec warranty covers this but dealer states it is not. Dealer is West Herr Chevy, East Syracuse. Had to wait two weeks with the problem and then they left me stranded at the dealer ship because they did not fix it. This dealer had computer issues and sent service home early and left me without a ride home when I returned. GM needs to notify these dealerships that this problem is covered.

While driving, an engine warning "Reduced propulsion Message" came on. Then it said " Engine Unavailable". The car would not go to gas engine. We panicked as we were 20mi from home and only had a few miles of electric left. I was able to drive to the nearest Chevrolet Dealership. It has been sitting there parked for 2 months. Uncharged. We are told that the problem is the EGR valve but no part is available anywhere. It is a known problem but GM has no parts available to fix. I am not getting any answer as to how long it may take to get the part. Meanwhile, I am without a vehicle. I only have approx 25,000 on the car. We have not been given a replacement car or been given any clear response from GM or the Dealership as to how long this may take to locate a part.

My 2018 Volt had a reduced propulsion power message and stopped running on its ICE in early Oct 2023 and because the battery was dead the vehicle wouldn't run at all. The next day 10-3-23 I was able to charge the battery and then brought the vehicle to the dealer for diagnosis. The problem seems to be with the EGR valve and the dealer ordered one at that time. It's been 3 1/2 months and there is no sign of the part. The car is only usable for its 55 mile all electric range which is often not enough but our family by borrowing cars and getting taxi rides and taking buses. This is by most measures unacceptable.

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!!!!

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.

2PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025
Status: closed (inferred from source dates) · Electrical System; Electrical System:propulsion System; Electrical System:propulsion System:traction Battery:management System/energy Control Module (bms/becm)
On November 29, 2023, the Office of Defects Investigations (ODI) opened PE23022 to investigate allegations of a loss of motive power, including a stall, reduced power state, and/or a no start condition due to the Battery Energy Control Module (BECM) in model year (MY) 2016-2019 Chevrolet Volt passenger car vehicles manufactured by General Motors (GM). The BECM is located within the high voltage electric vehicle (EV) battery pack and monitors the temperature, current, and voltage of the high voltage battery cell groups. GM stated that the root cause was identified as an internal failure leading to a loss of communication within the BECM and does not pose a risk to motor vehicle safety. GM further stated that the failure cannot result in a complete stall, only a reduced power mode, no start condition, or a no charge condition. GM additionally stated that if these conditions occur, the driver will be warned via a Malfunction Indicator Lamp (MIL) and/or a reduced-propulsion message in the Driver Information Center (DIC). Data received and analyzed by ODI from all sources indicates that nearly all related BECM failures caused conditions aligning with GM’s predicted outcomes. Despite the large number of warranty claims, nearly all failures were not safety-related, i.e., not a stall or reduced power mode. ODI isaware of a single minor crash and no injuries or deaths. In March 2024, GM issued Special Coverage N232432680, which was mailed to consumers, addressing BECM failures in certain MY 2016-2018 Chevrolet Volt vehicles. This special coverage provides an extension of the warranty coverage for the BECM from 8 years / 100,000 miles to 15 years / 150,000 miles for all 2016-2018 Chevrolet Volts. Additionally, GM stated that replacement components are sourced from a different supplier and not susceptible to the failure. In view of the Special Coverage issued by GM, the existing warranty coverage already in place, and the low number of safety-related occurrences, ODI is closing this Preliminary Evaluation (PE). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
