2017 CHEVROLET VOLT Electrical System Problems

Starting June 2024 my car started s displaying the check engine light with the message “Propulsion power is reduced” when driving on electric. When the message is displayed it switches to gas even if it has a full charge. Since June 2024 the check engine light is mostly on but sometimes turns off when electric is depleted and it’s running on gas. The message is randomly displayed when I accelerate

Car had not properly charged for the last 2 nights despite saying it was charging the entire time. When leaving my residence the car suddenly stopped working and I had to pull off to the side of the road with no power. The car was then stuck in park and would not turn off.

While driving my 2017 Chevy Volt on the highway, a “Propulsion power is reduced” message appeared accompanied by the CEL. Prior to this there had been no indication that anything was wrong. The warning was quite vague and it wasn’t at all clear what it actually meant so I continued driving. Shortly after this, I began to notice a bit of a “chuggle” or lurching sensation (particularly on hills). This made the acceleration slightly unpredictable, and at one point even triggered the forward collision warning when the car accelerated a bit after I took my foot off the gas pedal (coming up behind another car at a traffic light). I pulled over and attempted to figure out what the issue was. I had a notice regarding the BECM recall in my glove box which listed a reduced power mode as a potential symptom, so I scheduled a service appointment (figuring...

My BECM (battery energy control module) failed. Chevy recalled this for “some” Volts of my year, but not mine. It cost $3k to fix. How can they say my BECM was not defective if it failed? They knew it wasn’t working and recalled it for some, but not all. They need to recall all Volts becm. This feels very shady.

[XXX], while driving on [XXX], check engine light came on with reduced propulsion warning. Continued driving to destination without incidence. Did not drive again until [XXX]. [XXX] while driving using "hold" method of propulsion using internal combustion engine, check engine light remained on, after the engine warmed up, all of the sudden, there was a noticeable reduction of power, followed shortly by the internal combustion engine shutting off while I was entering onto an interstate highway ramp. Fortunately I was able to pull off to the side of the road and back down the ramp without incidence and return home under grossly reduced battery propulsion. July 8, took vehicle to Chevrolet dealership (Baierl Chevrolet, Wexford PA) under battery power. Was told ECM module was bad. ECM module was replaced, error codes cleared, vehicle ran as expected. after driving approximately 50 miles, check engine light with reduced propulsion warning returned. Turned...

I had the BECM fail as part of many 2017 volts with this issue at around 40K miles. This failure has caused multiple near accidents with immediately losing power at highway speeds. The last time this happened (after the BECM was replaced) was a couple of weeks ago. They said the reason for the failure was a programming issue, and they have updated it. It is flabbergasting to me that a programming issue can result in such a dangerous result. The car reduced propulsion on the highway and got stuck on the offramp while trying to pull over on the busy highway. Not only were we left stranded on the highway with me being 8 and a half months pregnant, but my husband almost got into an accident twice while trying to make it over safely. Chevy needs to be accountable for these significant failures that seem to continuously happen...

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.

On a recent trip on a highway on our 2017 Chevy Volt, the Exhaust Gas Recirculation [EGR] failed and caused "low propulsion" errors. We ended up with a surprise bill of more than a thousand dollars to replace the EGR cooler assembly, but the problem was not resolved. The dealership then said we need to replace the EGR Valve which is estimated above $2700 plus labor. Upon checking the GM-Volt users community this is a reoccurring issue on several thousands of vehicles and the inflated price is due to the fact that GM redesigned the EGR valve to fix their original faulty design. We as consumers shouldn't be responsible for such an outrageous cost and mainly safety due to a design flow by GM. This issue should warrant a recall by GM to fix the issue once and for all.

The EGR valve had an electrical short, causing the 15A F03 fuse to blow. This causes a "reduced propulsion" message to appear and also causes the vehicle to start overheating. The faulty EGR valve is available for inspection. This failure occurred while we were on the interstate driving 70mph. We were also at least an hour from home/family. The EGR valve short is a known problem with Gen 2 Chevy Volts. Online message boards are filled with posts about this issue. The vehicle was inspected by a Chevy dealership (we had to have it towed). However, the EGR valve is on national backorder with no ETA on when they would be available again. We are currently driving the car with the valve unplugged. However, this causes the engine to run less efficiently and at higher temperatures, so we cannot run it for long periods of time. There were no warnings...

Driving at freeway speeds when suddenly the cars propulsion power failed and I went from 75mph to 45mph with no warning and no way to accelerate. Happened multiple times even after pulling over and turning the car on and off. I was told by the dealership that was a gas engine part and that I could drive it on the electrical engine only. When attempting to drive on the electrical engine, I received a notice of engine failure and had to coast into the driveway of a dealership. I was told the engine “could explode” if I continue to drive it

The car stalled at a high rate of speed on a freeway because of EGR failure. Engine check light is on, along with a warning about a critical problem with emissions system that requires immediate attention. The part is out of stock in all dealership within a reasonable reach. The problem is under warranty, but I have made multiple attempts to fix this issue with no success.

Intermittently, I can't shut off my Volt. The following message is displayed: "Shift to Park"

Driving at highway speed car would slow down on its own and go into "Reduced Propulsion Mode"

The contact owns a 2017 Chevrolet Volt. The contact stated that while his daughter was driving at an undisclosed speed, the check engine warning light illuminated. The contact stated that the next morning when he attempted to start the vehicle, the vehicle made an abnormally loud sound. The contact shifted into reverse and the vehicle stalled. The vehicle was towed to the dealer. The vehicle was diagnosed with a battery malfunction. The vehicle was repaired; however, the check engine warning light remained illuminated. The contact related the failure to Manufacturer Communication Number: 10251431 (Electrical System) and TSB Number: N232422680 (Special Coverage Battery Energy Control Module Malfunction). The manufacturer was made aware of the failure and the contact was informed that the vehicle was not included. The failure mileage was approximately 142,974.

My service engine light came on. After that happened, my engine started to get hot. It got up to 230degF, received a reduced propulsion message and wanted to shut down when going 70mph on the interstate (depended on the construction). Quick reaction on my side before the engine shut down I had "held" the battery (which i do for long trips to ensure options in event of emergencies). Meaning i still had energy in the battery that could be used to propel the vehicle. I was able to shut down the engine by unholding the battery before losing control of the vehicle due to no propulsion. The electric propulsion took over and I could get off the freeway. Conditions were: I was driving in a rain storm on a very busy interstate around Eau Claire wisconsin right around 5-6pm with lots of road construction. If I would have lost the...

While car will turn on as normal, wheb put I to drive is says "Action Required - Shift to Park". The CEL code indicates, among other things, "EV/Hybrid Battery ppsitive contactor circuit stuck closed". I've read this has happened to may owners. Reading online seems to indicate

Shift to park warning comes and car will will not shut down I have already had this repaired in 2019

Had to replace EGR valve after losing power on the highway back in 2022. Lost power steering and reduced engine power while driving at highway speeds, luckily was able to get off the highway and limp the car back to my house. I almost crashed due to loosing engine power and power steering. It's appears to be a BECM issue.

We bought the car for our son when he began to drive. We liked the idea that it was gas and electric. At the time, our son was into electric vehicles. At 44, 000 miles, 7/10/20 the car was taken to the dealership. The engine light was on at this point, the message displayed "Propulsion Power is Reduced". Once the diagnostic was done it was said that the EGR valve needed replacing. Of course, this is during the of COVID. Everything was shut down. No one is working. It is now a wait game. Prior to this our Chevy Volt has been in and out of the dealership with either recall or something else. We enjoy the car because of how it operates with gas and electric. Fast forward it is 80,000 miles now, and the car is at the dealership again. It has currently been there for almost a...

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving at approximately 60 MPH, the Battery Range Zero Miles message displayed, and the check engine warning light illuminated. The Propulsion Power Reduced message was then displayed, and the engine inadvertently shut off. The contact coasted the vehicle to the side of the road and shifted the transmission into park(P) when the Shift to Park message was displayed. The vehicle was towed to the dealer, who reprogrammed the power inverter module, and cleared the DTC codes. The failure recurred 60 days later, and the vehicle was towed to Chevrolet Van Nuys (5949 Van Nuys Blvd, Van Nuys, CA 91401), where the 12V battery was replaced and the DTC codes were cleared; however, the failure persisted. The vehicle was towed back to Chevrolet Van Nuys (5949 Van Nuys Blvd, Van Nuys, CA 91401), but the vehicle was not yet...

On 2/11/23, our 2017 Chevrolet Volt displayed a check engine light and the engine started to overheat, as determined by the driver from the dash coolant temperate display, while driving down the interstate after 1 hour of driving. The car was pulled over to the side of the road and towed home. Upon inspection of the Chevy Volt later, the F03 15 amp mini-fuse(referred to as non-walk home fuse) in the main engine fuse block had blown, which had likely caused the electronically controlled thermostat to close and the engine to quickly overheat, due to lack of coolant. The reason why the F03 15 amp mini-fuse blew is because the control board for the EGR valve catastrophically failed and overloaded the fuse of this important shared electrical circuit. The electronic thermostat is part of this shared circuit, in addition to the EGR valve and possibly other important vehicle functions. I...

50 miles into a 500 mile trip, my Volt displayed a warning message, "propulsion power reduced." It operated almost normally for the first 250 miles and we were able to reach our destination, but the propulsion battery was not able to recharge from the engine power as efficiently as usual. An auto shop at the destination who does not specialize in EVs examined the car and found a fault in the engine control module, but the car was otherwise in drivable condition. On returning home, the car was required to climb a long steep hill. It gave the message "engine unavailable" on the freeway and began running on its battery reserves, which were barely enough to reach the nearest exit. If the car had run out of battery reserves where pulling over to stop would be unsafe, a dangerous situation would have resulted. The car had to be towed home....

WE WERE DRIVING IN TRAFFIC. THE BATTERY HAD PLENTY OF CHARGE. SUDDENLY, THERE WAS A WARNING NOTICE ABOUT PROPULSION POWER PROBLEM AND THE CAR CONVERTED TO GASOLINE MODE. WE CONTINUED TO DESTINATION AND PARKED. WHEN WE WENT TO START THE CAR, IT WOULD NOT START AT ALL. HAD CAR TOWED TO OUR LOCAL CHEVROLET DEALERSHIP (ALL SERVICE DONE THERE) AND THAT IS WHERE IT IS STILL SITTING. THE PART NEEDED (BATTERY) IS ON BACK ORDER. THIS OCCURRED ON JULY 21, 2023. TODAY IS MARCH 13, 2024! AS OF TODAY....APPROACHING 250 DAYS SITTING IN THE DEALERSHIP OPEN LOT,

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.

Propulsion error, steering wheel locked up today, last week shut off to dead stop while idling, trouble restarting. Speed and sudden battery drop issues. 14 miles without any power steering. Unsafe.

Took Vehicle into the local auto store to scan a engine alert and the error came up as P1E00 Hybrid Powertrain Control Module or the BECM (battery energy control module). After looking the error code up and researching online, found that many of the same symptoms are happening. The car wonts start intermittently and a message saying there is a power loss. last night the message came up and even though the battery showed full charge, it was running on Gas and only capable to speeds around 40-45 mph.

EGR valve failed, and car stopped driving on the highway.

I was traveling at 75 mph with the cruise control on when a message came on about reduced purpulsion. My vehicle lost all power and rapidly decreased speed, the gas pedal did nothing until my speed had dropped under 60 mph. I was on the freeway and could have caused an accident. Chevrolet says a programming update was needed to fix the problem but my BECM is now also out.

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.

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.

Vehicle lost power on highway and on local streets. “Propulsion power reduced” warning. Car brought to dealer 7/2023. EGR valve ordered at that time. The EGR valve has not been available since that time. No time frame for availability has been given.

My vehicle shut down in the middle of the road. GM diagnosed it as a faulty BECM.

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...

Car won't start show codes U2622, U2621, U2620, U2619, P0AFA.

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...

First, the electrical system did fail suddenly in August 2023. Luckily, I was parked and so was not injured. I did report the electrical failure to the Hendrick Chevrolet dealership in Durham. But this Chevrolet Volt also does not fill up with gas. At the pump, gas just spills out of the tank. I've seen online that many people have this same problem. At the suggestion of Hendrick Chevrolet dealership in Durham (and after paying $210 for a diagnostic), I replaced the vent valve solenoid. The car filled up with gas twice. But once again, gas starts spilling out of the tank if you try and fill it up. The car only has about 25,000 miles on it and hasn't been driven extensively so it doesn't make sense that it is malfunctioning.

We were driving on the highway (my wife and younger son were passengers, and my 17 year old son was driver). He was in electric mode and then the engine propulsion reduced message came on and the check engine light came on. Car was still running, albeit slower. We stopped and filled up the gas, and got an engine unavailable message. Vehicle switched back to battery mode on its own and because there was no charge, the vehicle stopped ON THE HIGHWAY. The car lost all control and power abilities and it was very dangerous. They were able to pull over into the break down lane and they called a tow. Took the car to Mike Reichenbach Chevrolet in SC and they removed and replaced the EGR valve. However, within the last couple of weeks, my son has received the loss of propulsion message again and the car is violently...

Upon starting vehicle and shifting to drive, vehicle gives message to "shift to park" and will do nothing else. Also, while battery is fully charged, vehicle will display "unable to charge" and show no mileage left on EV mode - then at times (but not always) upon starting vehicle, mileage increases to what it expected.

The Volts BECM has failed. There are warning lights constantly warning about Engine and low Propulsion. There are multiple symptoms. Most serious is that car has stalled while driving 3 times. If I pull over, put in park, then turn off; I can restart the engine using battery mode. It does not drive well in gas mode where gas fuels generator to charge battery for propulsion. It is now very loud and often won't allow you to drive faster than 30 MPH. The mileage diagnostics (MPG) are just over 50% of what they were before problem started. It often randomly switches from battery mode to gas. This is undesired. My problem is that the only certified tech is on other side of Island Volcano. I have no confidence that I can drive it to dealer, given the distance and power required to climb mountain. So, I am stuck with no...

Vehicle suddenly would not function. All systems became inoperable. When serviced it was determined to be a sudden failure of the BECM module which required total replacement. Part was on national back order leaving vehicle unusable for weeks.

My Chevy Volt has been having spotty pop-ups stating that "Propulsion Power is Reduced" for about a month, but I was not sure how reliable the pop-up was as there were plenty of days the pop-up would not come on when starting the car. On the day of my incident in October 2023, I once again received the "Propulsion Power is Reduced" pop-up when I started my car. While driving, I stopped at a stoplight, and my battery drained. When the battery is drained, I usually don't have anything to worry about, as the Volt is an EV hybrid, and I can use the gas until I can charge my vehicle again. But the Check Engine Light came on when the battery drained this time. When the light became green, I started to drive like normal, but I suddenly got a pop-up on the screen regarding the engine no longer...

Failure of the BECM and “Shift to park” message. The vehicle will spontaneously produce a shift to park message when starting up the vehicle and turning it off. The vehicle will also show a 0 mile EV range and use the engine where a message saying “propulsion power reduced”. This will also cause the car to shut off randomly. The vehicle has not been inspected by a shop or the dealership. There is no warning or message when this happen. Check engine will appear once the vehicle has these issues.

so we inspected your vehicle and it needs a battery module, that part is on back order and we have no ETA when it will come in. That is what the dealership sent me. There are people on Chevy Volt forums saying it's the EGR valve and they've been waiting months with non-working cars. Is anyone doing their job around here?

EGR valve failed. Dealer supplied part has been on back order for more than five months.

I was driving and then the car turned off and was unable to restart. There was no warning. The car was fine and then it wasn't. The power steering also stops working. Fortunately I was at a red light and not in the intersection yet. The check engine light wasn't on. The BECM (battery control module) failed. I had to get the car towed to the dealership for the repair. The dealership repaired the issue for free since I was still under warranty.

All of a sudden while braking on a freeway offramp, the check engine light came on and a reduced propulsion warning came on my screen. The car ran weird for about a day, then it wouldn't start. I had it towed to a dealer, they diagnosed the BECM went bad, now my car has been there 2.5 weeks and there's no estimated ship date for the part, much less repair date. If they said they had enough parts for BECM failures, they're either lying to you or they're lying to me.

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving approximately 65 MPH, the vehicle suddenly lost power and decelerated to 35 MPH. During the failure, the message "Reduced Power" was displayed. After turning off and restarting the vehicle, the failure remained, and the vehicle was driven to the residence at a reduced speed. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted. The failure mileage was 26,000.
