Driving at highway speeds, check engine light came on with a warning of "reduced propulsion power" and sudden loss of speed in heavy traffic. Dealer diagnosed issue as failed EGR valve but is unable to source repair part due to frequency of failure causing years-long backorder.
check engine light has been on since Oct of 2023 due to needing EGR valve. Dealership placed order for part number 12691147 in Oct and says it has been on backorder from GM with no estimated delivery date. I just placed an order for the same part via GM parts center. Again, says on backorder. Is there anyway to get a hold of GM parts to escalate getting this? We cannot get the car inspected with this issue and are worried about the safety of the car.
Battery Energy Control Module (BECM) loss of power or reduced power mode occurred came with little to no warning. Hybrid battery wouldn-??t accept a charge in its battery.
The contact owns a 2017 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the vehicle suddenly lost motive power, after which a message displayed, "Propulsion Power Reduced". There was no warning light illuminated. The vehicle was taken to the dealer, who determined that the drivetrain fluid needed to be replaced. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 78,000.

On [XXX] while traveling at highway speed my Chevrolet volt abruptly lost propulsion and an alert was displayed to pull over and turn car off. I was on [XXX] in California a 4 lane highway forced to cross 3 lanes of traffic at an exceptionally slow speed in heavy traffic. It is a miracle a crash did not occur. Fortunately other drivers were aware and able to stop or quickly change lanes. AAA towed directly to Stewart Chevrolet in Colma Ca. It was diagnosed and I was advised it is under warranty HOWEVER parts are on back order. Today [XXX] ~ the car still has not been repaired and I have been advised parts will not ship until September 2024. This is both dangerous and unacceptable.

My car is lurching very dramatically while on battery-only. Especially over 35-40 miles an hour. I was run off the road last week and am becoming fearful for my safety in this car. I have heard that there may be something wrong with the battery or. BECM.
The EGR valve had failed, causing a check engine light, which turned into a blown fuse. The fuse blowing left the vehicle stranded until I unplugged the EGR valve and replaced the fuse. I drove it to a shop, where they replaced the valve and the car has been functional since then.
I am writing to report a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the Provo Utah Chevrolet dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. However, upon arriving for the appointment at 4:00 PM, I was informed that the hybrid mechanic had left for the day, and I was asked to return on another day. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024, while driving to work, I experienced a loss of propulsion power on the highway, placing my safety at risk. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. I urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly to ensure the safety of Chevy Volt drivers and passengers. It is imperative that General Motors addresses these issues promptly and implements appropriate measures to prevent further incidents.
Was driving home from work and my car just stopped check engine light came one the engine came on but then went off and i was stranded my issurance came threw with a tow but from all good to a complete stop sucks
Car would not start, lose power, or show propulsion reduced message. This seemed to have been an ongoing issue related to cold weather (bought in July 2019) and would occasionally get temporary check engine lights. Dec 2022 and Jan 2023 cold weather seemed to aggravate w car no starting on occasion. Eventually by January car started propulsion reduced error. Turned out to be BECM (which had been under service bulletin in 2019). Other related repairs like shift to park issue and drained 12 volt battery also repaired at MY personal cost of nearly $4,000. The propulsion issue almost led to some accidents when it would happen pulling into road or on highway driving.
BECM failure on car confirmed at 128,000 miles. While driving the car's check engine light came on; immediately followed by a message of reduced propulsion and the EV range dropping to 0. Vehicle switched to gas and ran very rough for a short distance to an available stop. Have been informed by dealership that the vehicle is now unsafe for driving due to a potential stall.
same issue as PE23022 and TSB 18-NA-261 Called 51 parts wharehouses and Chevy dealers to locate part. They all report the same: part is not available and no idea when it will be come available. vehicle is not mobile without working part. Vehicle has lost propulsion while driving. Twice I was lucky no one was behind or on the side of me that I could pull off to the side of the road or a parking lot.
1 month ago was driving on toll and Population power is reduced came on, vehicle was reaving high and felt like power was being reduced/speed, was going 70 and had to immediately decrease speed and get off toll and found closest Chevy shop. Looked at dash and vehicle should have had at least 10 energy miles but it had immediately dropped down to 0. Before taking to Chevy, I had a quick inspection done by a Valvoline shop and they told me the battery had to be replaced. Carvana (Silverrock) warranty refused to do the repair under their coverages as -??batteries were not covered under warranty-?? Had it towed from Valvoline to Chevy. Found out Chevy battery was under warranty so it was taken there. Vehicle was checked in and didn-??t have an eta as hybrid battery was on back order with no ETA. 3 weeks later the part was received and it was a control module not a battery as the -??battery was not failing at the time-??. Service called and said vehicle was ready for pick up. Had vehicle for 1 week and was at work starting it up and after 9 hours sitting started it up and low population came back on and vehicle started idling higher than before then after a minute looked at back of car and a large cloud of while smoke started forming from back of vehicle. Immediately turned off car and called gmc roadside assistance to have vehicle towed to another dealership where is it sitting again for diagnosis with no eta.
While driving in 60 degree weather, the vehicle-??s check engine light lit on the dash and the vehicle abruptly stopped. I was able to push the vehicle safely in heavy traffic. I contacted Onstar who gave me the vehicle diagnosis. Onstar advised the following codes appeared POACA (Hybrid/ electric vehicle powertrain control module requested malfunction indicator lamp illumination), P1AEE ( the electric propulsion system is not performing as expected. Please service immediately), and P1AEF (the electric propulsion system is not performing as expected).
Car stopped operation while out doing errands. Car had to be parked and restarted and made it back home. Car would not start again. Had to have it towed to dealership, BECM needs replaced for $2000. Warranty should cover, but part is backordered. Not sure when it will be fixed and with the recent freezing temperatures could have been dangerous.
Vehicle stopped running, will not restart. ODB codes show failure of the BECM. Check engine light illuminated, READY indication turned off. Vehicle does not display battery or fuel status. We were left stranded by this failure.
While driving the car in electric mode, a chime came on and flashed 'propulsion power is reduced', then it went into engine mode and the car decelerated quickly from posted 70mph speed to less than 40mph even though I pushed the accelerator pedal and reved the engine high. While in this low power driving mode, a warning came on saying the collision detection system was disabled. The concern is the person behind me had no warning since my brake lights did not come on. He sped around me with a bit of road rage. The problem temporarily goes away when you turn the ignition off and back on. I took it to the dealer and the said it needed a new EGR Cooler 4 hours labor $1500. Chevy Dealer pulled two codes P0401 Exhaust Gas Recirculation "A" Flow Insufficient Detected P1E00 Hybrid/EV Powertrain Control Module 2 I paid them the $165 diagnosis fee and got my car back and just plan to restart when it occurs. In another instance, I was pulling out from a parking lot into a busy road in electric mode and the car lost ALL power leaving me exposed in the line of traffic. Error messages on the dash said to 'service BECM' and 'shift to park'. The car was not drivable and had to be towed. Call me if you need any more information.
