2017 CHEVROLET VOLT Fuelpropulsion System Problems

Several years ago, when I was driving the vehicle, I got a sudden "reduced propulsion alert" and the onboard coolant temperature gauge showed a significant spike in temperature. To avoid overheating, I had to pull over on the side of the highway. In the onboard fuse box, there was a blown F3 fuse. I replaced the fuse and the same issue happened again last year. After some online research, it is clear that the EGR valve failed. Unplugging the valve and replacing the fuse has returned the vehicle to normal operations, but it's now out of compliance with local emissions regulations. GM has failed to properly produce replacement parts. As of Feb 11, 2026, a local GM dealer in Bloomington, IN quoted a backorder and unclear wait time on a replacement part and quoted me at $2,000+ just for the part. If not for my quick thinking, this part failure...

There is a ongoing problem with the BECM on 2016-2018 volts. Mine is one of them. Contacted Chevrolet and they say my vin isn’t under the extended coverage. I believe it should be and can’t stand they won’t cover my car under warranty. Is there anything you can do?

My car started having issues with the hybrid system, with fault alerts related to the drive motor control module, hybrid powertrain control module, and battery energy control module in the transmission, and the vehicle is available for inspection if needed. The engine light had been on for about a week, and I was waiting for availability at work to take it to a mechanic. While driving around 70 mph on the highway, a “Propulsion Power Reduced” message suddenly came on and the car started limiting its speed. As I kept driving, the power continued to drop, making it unsafe to stay at highway speeds and putting both me and other drivers at risk since the car couldn’t keep up with traffic and could slow down unexpectedly. I took it to an independent mechanic who confirmed the issue and warned me it was dangerous to drive because the speed would keep...

Experiencing intermittent propulsion system failure with multiple simultaneous warning messages on 2017 Chevrolet Volt at approximately 59,000 miles. WARNINGS DISPLAYED: - "Propulsion Power Reduced" message - "Check Tire Pressure Monitoring System" (false alert - all tires properly inflated and recently replaced) - Multiple dashboard warning lights including exclamation point indicators - Vehicle exhibits abnormal driving characteristics PATTERN: Issue occurs intermittently while driving. Vehicle can be restarted and may operate normally afterward, then fault returns unpredictably. SAFETY CONCERN: This matches documented Battery Energy Control Module (BECM) failure pattern referenced in GM investigation N232432680/PE23022 and Customer Satisfaction Program 17228 recall N172096420 for reduced propulsion power in 2016-2018 Volts. Review of owner complaints shows other 2017 Volt owners experiencing sudden complete loss of propulsion while driving at highway speeds, creating dangerous situations requiring evasive action by other drivers. RISK: Loss of propulsion power while driving with dependent passengers creates serious crash risk. Vehicle...

The BECM (Battery Energy Control Module) failed. The vehicle illuminated the MIL and the driver display to show a "Reduced power". When restarted, the display showed "shift to park", which I did several times. After a couple of restarts it displayed the "Reduced power" message, but would not go into drive. THE MIL was illuminated the entire time. Through numerous key cycles I got the VIN operable and took it to the dealer for repair. The BECM part is at the dealer or on its way back to GM as a core return. While this occurred while I was leaving my garage, it could have occurred in traffic, which would put me or others at risk. The problem was investigated by my local dealer (Currie Chevrolet in Forest Park, IL) and it was determined to be both a bad Battery Energy Control Module (BECM) and a bad shifter assembly. The...

On 10/14, I was driving the car to my job, when the car suddenly switched from its electric battery power to its internal combustion engine. The vehicle's information screen only showed that the battery was unavailable. I was able to operate the car on only the internal combustion engine to arrive at work. However, when I went to leave several hours later, the car would not start. The car was towed to a dealership and apparently repaired after about a week. However, the repair, a software reset, did not fixt the underlying issues, and on 10/27, after having the car for five days, the car again failed on my way to work, displaying a "Shift to Park" message and not starting. I towed the car to the same dealership, and they had it until 11/04. I recovered my car and drove it again to work that same day, but the...

I was driving in stop and go traffic on a relatively busy road when I was cut off. I braked hard to avoid a collision. Immediately afterwards, the car would not respond to the accelerator and would not go forward. I was in the middle of the road and the car would not respond. It could have caused an accident. I put the car into park and then back into drive and it seemed to work again. But I am now worried about the car.

I am reporting 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 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. Subsequently, on February 11th,...

Vehicle propulsion system failed. According to Chevy dealer the Battery Energy Control Module and A/T Control Park Switch and harness failed. Warning lights came on when the failure happened. Failure happened just past the extended 150k mile warranty. But car in only 8 years old.

My EGR system caused a check engine light. P0401 This is an extremely well documented issue on Gen2 Volts, especially 2017 models. Simply searching "EGR" on the Volt subreddit or forums returns hundreds of related threads. This issue can lead to a clogged EGR valve, causing further damage. A temporary resolution is unplugging the EGR valve, which i have not yet done. But this leaves the CEL illuminated, and without daily scanner, I wouls not know if other issues arise, causing a significant safety hazard.

EGR Valve failed in this vehicle <55,000 miles. The EGR valve has an electronic component that, when fails, can cause the car to shut down by blowing the "walk home" fuse. This is a safety issue. This is a well documented problem (internet) and Chevrolet refuses to fix it, leaving the owners with an expensive replacement quoted at $3900 (Sept 2025). Recommend that it be covered by the emissions warranty, which was recently extended to 150,000 miles and 8 years for other problematic emissions components. An electric vehicle that cannot be driven because an EGR valve is faulty - it's a joke.

Check engine light came on car was able to start but the cluster started reading the battery being full with a charge. And was having trouble starting. Fast forward a day I get a propulsion system reduced warning on the dash as I’m entering the highway and the car fails to stay on I’m able to pull it to the shoulder and I cannot get the car to start. Get towed home throw it on the charger and the dash says unable to charge. swap the 12v (checked it and it died) thinking that might fix the problem since the car was able to power on but not start. To no avail through my code reader and code p1e00 code. Took it to my local dealer and was told id need replace the becm… and was quoted 33xx for the repair. Had any of this happened while I was on...

Propulsion power reduced and check engine light came on my 2017 Chevy volt - been happening a few times now the last week

I was driving my car from Houston to Dallas when I got the "reduced propulsion" message and a check engine light. When I first saw the reduced propulsion issue I thought it might be related to the BECM issue again since I had already experienced that problem before. In the last few minutes of my trip the AC started to get hot and when I checked the coolant temperature I noticed it was around 240 - 255 F. I hadn't noticed it since there was no warning light for high temperature which I am used to with other cars. I'm not sure of the full extent of the issues yet, but I know for certain that the EGR valve has failed completely at about 71,500 miles. This is with very few miles on the actual ICE. I typically only use the ICE for a few hundred miles of driving each...

While driving approximately 65 MPH on an interstate highway, the vehicle's check engine light illuminated. Very shortly after, the dashboard screen displayed the message "propulsion power reduced," and the internal combustion engine turned on. The vehicle's power was significantly reduced, almost causing an accident when another car started merging without checking their blind spot, forcing me into the left lane in front of a third vehicle that had to brake sharply to allow me to accelerate to keep up with traffic in that lane. Upon scanning the vehicle with an OBDII reader, codes P1E00, P1F06, U2603, U2604, U2605, U2606, U2617, and U2618 were present. Together, these codes indicate an issue with the Battery Energy Control Module (BECM). The vehicle is currently at a Chevrolet dealer, awaiting replacement of the BECM under the applicable warranty extension.

Portion message car stalled on hey

Driving on interstate doing 65 and suddenly warning pops up and car dies immediately. I was lucky to get over to the edge and not wreck or cause an accident. Found that the 12 volt battery was not being charged without warning until failure. Found a 15 amp fuse blown in the high voltage relay module.

I got a warning from my car a little over a week ago (around 6/1, unsure of exact date) that I needed to service the battery charging system, but then the check engine indicator light shut off and so did the warning light. The hybrid battery took a charge with no issues after that. Then, I left work the evening of 6/9 and drove home. On my way home, the check engine light came back on, followed by warnings that I needed to shift to park. Before I could pull over, my car stopped moving. Cars had to stop abruptly behind me and navigate around me into incoming traffic. I shifted to park, then tried to turn my car off and on again. I tried to switch between the gas engine and the battery, I tried to move my vehicle in any way. I couldn't get it into neutral to...

While driving the vehicle, the car shut down. Thankfully I was coming to a yield at a round about after exiting the Interstate. I was finally able to get it to restart and proceeded on my way. If this had happened on the Interstate myself, and other drivers would be at risk due to unassisted steering and braking. I also have experienced intermittent periods of "Reduction of Power" while on the interstate and other 55MPH plus highways. This presents a hazard to myself and other drivers as well. These issues ARE covered for similar vehicles under Special Warranty Coverage N232432680 as required by NHTSA on March 6, 2024. My vehicle also exhibits all of the primary symptoms described in that coverage, but GM claims that my vehicle is NOT covered. CEL is on. Can't charge condition Reduced power No start condition

There was a recall for the HPCM2 where the propulsion power reduced warning would come on whenever the car's cell battery was depleted. This happened with my car and there were several times it slowed on the freeway and on exit ramps as I tried to safely get my car off the road. It first happened on 4/13/25. I took my car to a regular mechanic who charged me 3k of repairs on basic maintenance, new tires, etc but were unable to fix this issue. They advised it was a manufacturer issue and to go to a hybrid specialist or a dealership. I called a hybrid specialist who found the faulty code and advised the same. I took my car to Felix Chevrolet (3330 S. Figueroa St. LA, CA 90007) and they offered to do many maintenance service items that I had done earlier this week in an attempt to...

Unknown My car has been accelerating and decelerating on it’s own while I’m driving.I got it checked with Fix Finder and states that my EGR Valve and ABS System failed. I brought it to a mechanic for a repair and I was told that the valve was unplugged so they plugged it back in and cleaned it , and said that everything was fine it said it might also be the cause of the failed ABS System but everything looks fine. After I got it fixed, it’s doing the same again and it’s worse this time. The car is accelerating on it’s own faster than what it did but the dashboard is saying 0mph. I was driving in the highway when it happened and it’s scary so I had to pull over.

P0401 code caused the car to say “propulsion power is reduced”. I was on the highway and had to pull off to find a safe place.

Vehicle lost all motive power while driving on the Highway. Vehicle is part of GM Special Coverage program number N232432680 for BECM issues up to 150,000 miles. Vehicale currently has 109350 miles. Failure on highway while driving is unacceptable and should have been a recall instead of special warranty. GM support is not helpful with service or transportation (one month out for service only at select locations). Vehicle will not restart and had to be pushed from the roadway.

Battery Energy Control Module Failure There is an existing NTHSB issue related: N232432680 I was told my VIN is not included in this issue, so the failure is not covered under warranty by GM. That said, the same failure and symptoms occurred (prompt multiple battery cell failures leading to electric drive inoperable). I was told, by others with Volt's who had same issue, that my VIN was not included because it was under a PZEV warranty since it was originally sold in California. I do not live in California, so the extended 150K mile / 15 year warranty does not apply to me. Car is currently at the dealership, and I was told the same repairs as in this NTHSB issue are needed at a price of > $2,500. As such, I am asking to have my VIN added to this issue for reimbursement.

EGR Failed, which blew out the walk home fuse. THAT IS A SAFETY ISSUE. GM DISCOUNTUNUED VOLTS AND THE EGR VALUE IS NOT AVAILABLE WORLDWIDE.

My Chevy Volt went into Reduced Propulsion System Power Mode, the Engine light came on and the vehicle stalled while sitting at a traffic light on [XXX] at [XXX] in Tyler Texas. Checking the computer and the complaints online I found that my 15 AMP #03 fuse (No Walk Home) had blown. I replaced the fuse and the next day on [XXX] the same thing happened again after driving 30 miles. The vehicle stalled at an intersection outside of Tyler Texas. The EGR Valve is known to cause the fuse to blow, so I had no choice but to unplug the EGR Valve and replaced the fuse and has not blown the fuse since. This is BOTH a safety issue and an emissions issue, but the replacement part cannot be found anywhere to purchase anymore so I am having to drive this vehicle with this ongoing safety issue. Due to...

My car needs an Egr valve replacement and this is a known and common problem with this car and now they are trying to charge me outrageous prices for an issue that they know is defective. The becm , the Egr valve, and the shift to park. need to be recognized as recalls

On December 2023 the vehicle lost power and lost control while driving speed limit 55 Mph followed by check engine light associated codes due to known issue with BCEM controller failing. June 2024 Vehicle experienced the same issue with duplicate check engine codes associated with prior issue. Dealer states the vehicle has a bad battery pack and has been there for over 8 months. Vehicle has a BECM warranty due to a law suite filed and also has a battery pack warranty from GM that was extended for 150,000 miles or 10 years.

The EGR valve failed. This caused the vehicle to have insufficient propulsion while driving. The dealer has confirmed the EGR valve is the problem. The vehicle is at the dealership. The check engine light came on. The dealer is now stating the replacement EGR valve is a $4000 part because GM stopped making the part when they discontinued the Volt. An EGR valve should cost $250-$400 not $4000. The current trade-in value of my vehicle is only $7000. I cannot get my vehicle fixed due to the cost and the vehicle is too dangerous to drive due to the power loss issues.

The EGR Valve and EGR Cooler went out on the vehicle while driving on the highway, causing my propolsion power to decrease or rendered unusable. This also caused inconsistent engine pressure and caused my engine to overheat, having to pull over multiple times while driving. The problem has been diagnosed by a Chevorlet certified repair center. There were no warning lamps or messages until the problem began abrubtly while driving.

I was driving effortlessly down [XXX] between san francisco and santa cruz when suddenly i seemed to be losing power. Pressing the accelerator/gas pedal was not obtaining the usual result and I was going slower and slower by what felt like the second. I also noticed that it switched to gas although it said there were around 12 miles on the EV battery which was a sign that something was wrong. Fortunately there was a break and traffic was going at a speed which allowed me to make it across three lanes of traffic in just enough time for an alert posted on my dash saying something about loss of propulsion (not sure what it said exactly, because, i was driving!) and i coasted onto the shoulder, but barely. By that time it indicated that there were zero miles on the EV battery. (2 weeks prior I had been unable...

I was driving at about 50mph all of a sudden I got a propulsion error and my car stopped working it had no power! People had to swerve around me and I was almost hit. My car would not drive I shut it off and back on multiple times. Finally it started but would not go above 25 it was so scary. I went to the dealership they said it’s known issue since 2016 and that my miles were too high so it would not be covered to fix the total amount it almost 3,000 this seems unfair that Chevy would continue to sell a vehicle knowing it had issues with a energy control module and not fix it for free. Especially when you could be killed while driving it!!

N232432680 / PE23022 On some 2016-2018 model year Chevrolet Volt vehicles, a malfunction involving the battery energy control module (BECM) may cause a reduced power mode, a no start condition, or a no charge condition. The above safety issue required an extended warranty recall for *all* 2016-2018 Chevrolet Volts due to a known issue with failing battery energy control modules (BECM). The warranty was not extended to vehicles sold in CARB states, as the Partial Zero Emissions Vehicle (PZEV) warranty is the same as the extended warranty granted by the NHTSA investigation which resulted in the extended warranty noted above. (N232432680) However, it GM's practice to decline warranty coverage for a CARB vehicle with the PZEV warranty if it is not longer registered in a CARB state, thereby skirting around the special coverage from the NHTSA investigation. This is a circumvention of the findings by the NHTSA and the safety...

Propulsion Power Reduced and car had trouble breaking and would stall for a moment. Will not let me use the EV range even though the ev battery is at fully charge.

On [XXX] my 2017 Chevy Volt was having propulsion issues, and later would not start at all. This was not the first instance of propulsion issues, fortunately I was able to pull the vehicle into parking lots. The vehicle was towed to Midway Chevrolet, 2323 W Bell Road, Phoenix, AZ 85023. On Friday [XXX] the dealership called me to let me know the vehicle was ready for pickup. After my arrival at Midway the car was driven one last time and must have experienced trouble, so it was checked out. Midway then informed me that one of the 32 Battery Energy Control Module (BECM) was not producing enough voltage to propel the vehicle and not drivable. Midway ordered the replacement BECM and when I inquired several days later I was told the BECM was on backorder and they hoped to have the BECM in September 2024. In September I was...

Power surge I hit the gas to cross the highway and lack of power then got home the next morning started the car and it started serging in the driveway then it shut down altogether.

Problems with EGR valves still in defects, and engine gaz motor loose power. GM don’t have enough parts to resolve them.

This is a safety issue for Chevy Volt. After seven years of good operation, our 2017 Chevrolet Volt stopped running in traffic while we were driving on [XXX]. The Check Engine Light was on, and "Reduced Propulsion" Message on dashboard panel. We brought it to the dealer from whom we purchased the vehicle. Tech Report paraphrased, Customer states CK Engine Light is on and "Reduced Propulsion" Message on dash Fault Codes: P0030, P0031, P0054, P0135, P0403, P0405, P0443, P0458, P0489, P0597, P0598, P06DA, P06DB Found fuse [F03] blown for EGR valve Likely EGR Valve sticking and causing fuse to blow. The technician stated the Exhaust Gas Recirculation (EGR) Valve is defective, and needs to be replaced. Replacements are scarce, on backorder, and can be many weeks or months to wait for a part. Many report their Volt unusable, sitting idle, waiting for EGR replacement. EGR valve replacement cost is quoted...

My car stopped all of a sudden and lost power while my wife was driving. She could've been in a major accident since the car lost power. This has happened a few times in the past. Luckily she wasn't on the freeway or she could've been rear ended at highway speeds. There were warning lamps that said check engine and "Lost Propulsion". This should be looked at closely as my safety as well as the safety of others was at risk. VERY DANGEROUS SITUATION! I had my car towed to the nearest auto repair shop where it is being looked at.

The vehicle tells me to "stop and shift to park" while I am driving, and power was lost to accessories such as the climate control. Since the EGR was identified as the cause of the problem, the car remains on "Propulsion Power Reduced" mode. The EGR has been backordered for months, if not years, and aftermarket third-party EGR valves are not readily available either. However, there is no recall, and this is clearly a common problem on these vehicles as attested on GM-Volt forums. The EGR failed about one year ago, but now the message on reduced propulsion power is presented every time I start the vehicle.

On November 8, I was on a 5 hour drive and after 4 hours while driving on the gas engine since the 43 mile electric range was already depleted, a warning suddenly appeared on the dashboard screen - Shift to Park, something about reduced propulsion and the check engine light came on. I was driving 55 mph on a highway and immediately had no propulsion whatsoever. Tried to pull over and barely got to the edge of the highway with cars and trucks speeding behind me and then around me. On the roadside, the car would turn on and off and I could change gears with the shifter, but no matter what I did the propulsion to move the car would not work. The car had to be towed to the nearest dealership for repairs where it remains.

Was driving on highway when given error ""Propulsion Power Reduced." This resulted in less power available, which is a safety hazard. Then after a while of driving (on the highway) I received the error "Engine Not Available," which caused me to have to continue on electric only power. If I did not have any battery left in the traction battery, I would have had to maneuver to the shoulder. The error code revealed by a scan with the OBD device P0403 relates to a failed EGR valve. There are no replacement parts for this valve, according to GM, so future failure is likely.

Currently, two two issues are ongoing with my 2017 Chevrolet Volt Premier. I took my Volt to Epic Chevrolet in Sacramento, CA, on August 9, 2024, because the "Propulsion Power Is Reduced" warning and the "Service Park Assist System" warning came on with the "Check Engine" light. After diagnosis I was informed that the "EGR Valve" has failed; however, Chevrolet cannot procure the EGR Valve to repair my Volt and it is now October 14. I have been coordinating with Chevrolet Customer Assistance who continue to inform me that they are looking for the part but cannot provide it - apparently this part has been redesigned. This is the third time in 12 months that the Volt has been in for repair, all under warranty, for charging and propulsion related issues. On August 23, 2023, the Volt was in the shop for 15 days getting the "Battery Energy Control Module"...

Mil came on for egr malfunction. Part not available.

At least 4 times in the past 1.5 years, my car has given the message “propulsion power is reduced” at random times. Each time after receiving this message, the car engine begins making a loud noise and the acceleration is greatly reduced, forcing me to drive at a slower speed until the message goes away. The most recent time it happened, in Aug 2024, it was late at night in an area with little to no cell service and I was genuinely terrified the car would just shut down, as I knew this model has done the same to other Volt owners. Thankfully, I did make it home, but this is something that has happened more times than I’m comfortable with, and I fear the day it happens again and puts others at risk. It has not received any further inspection other than the yearly state inspection, which is up...

Automation-On 10.1.24 my car stopped working. It would turn on, but would not shift. It was also showing my EV was fully charged but the EV miles read 0. My husband came and plugged my car in and saw that when I turned the car on it read "shift to park" Also the codes from my OnStar app read "Lithium Ion Battery"- Issue found in High Voltage battery. "12 volt battery needs attention" 10.2.24 we called GM to report issues and referenced N232432680 (BCEM). We were informed that even though we can read diagnostic reports on OnStar it needed to be confirmed from a certified GM dealership that they could not confirm this is the warranty issue if they did not 1st had the certified dealership share their diagnostic report. Bergstrom shared it sounded like BECM that is under warranty. They continued to share it didnt look good and the...

While driving on the highway there was sudden power loss with a message on the display stating "propulsion reduced" and had to pull over.

As I understand it, the EGR valve failed causing the car to shut down suddenly on the highway. Apparently by blowing the "walk home" fuse. The EGR valve has been unavailable from GM worldwide since Oct 2023 and there is no estimate when it will, if ever, be available.

Reduced propulsion message appears on the dash and car lost propulsion on the highway. The EGR blew a fuse and the car enters the walk home mode. This problem should be covered under warranty but my dealership says it is not covered. This issue causes the car not to be able to drive. Chevy is back ordered for the part and there is no estimate of when the part will be available. They apparently do not make the part anymore and there is no fix. Th EGR seems to have bad soldering and blows the fuse #3.

While driving on high-speed devided highways including stretches where traffic was 2-way (single lanes separated by concrete barrier during road maintenance) Chevy Volt indicated "reduced propulsion", and in 2 cases forced shut-down of electric and gas engine where the single-lane travel had cement barriers on both sides of the driving lane.In at least one case, the engine forced 30-40 mph travel until a break in the right-hand cement barrier was interrupted and I could get off the highway. In another case, the engine and fuel propulsion shut down but there was a breakdown lane on the right allowing traffic flow but exposing me to risk due to how close 65 mph traffic was passiing me. In each failure case, after turning off and re-starting the vehicle, the vehicle seemed to have re-set propulsion control and I could continue the trip at normal speed until another warning but not complete faillure...
