2017 CHEVROLET VOLT Power Train Problems

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,...

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving approximately 35 - 40 MPH, the message stating that the propulsion was reduced was displayed, and the check engine warning light was illuminated. The contact continued to drive the vehicle, and the vehicle unintendedly decelerated. The contact arrived at the destination and parked the vehicle, and the message “Shift to Park” was displayed even though the gear shifter was in park(P). The message “Charging Unavailable” was displayed. The contact stated that while charging the vehicle, the mileage was reduced from 72 miles to approximately 29 miles during the winter months, and 42 miles during the summer months, while still indicating a FULL charge. The “Shift to Park” failure had occurred twice the previous year, and the vehicle was turned off and restarted to correct the failure. The vehicle was taken to a certified mechanic, who diagnosed that...

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...

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...

My 2017 Chevy Volt is having Battery Energy Control Module (BECM) issues. I receive the occasional error message of "propulsion is reduced" and engine fault codes of P1E00, U2619, U2620, U2621, U2622, U2623, and U2624. GM issued a Special Coverage bulletin (N232432680) extending the warranty for the Battery Energy Control Module (BECM) on 2016-2018 Chevy Volts to 15 years/150,000 miles. My Chevy Volt is within this year and mileage range, but for some reason my Chevy Volt VIN is not included in this Special Coverage (N232432680), which means that this special coverage for some reason doesn't apply to my 2017 Chevy Volt, even though it has the same issue. Is there a way that my 2017 Chevy Volt VIN can be added to this Special Coverage bulletin (N232432680) so that I can get warranty repairs? Thank you.

The engine light starts blinking and telling me propulsion power reduced, and then I cannot use the cruise control after that turns on, and it starts losing power, driving on I 70 after work all of a sudden it turned on and wet from going 76 miles an hour to 52 on highway I 70 where the speed limit was 75. This problem was a recall problem which was fixed and now is happening again on the same part and having the same problems.

The vehicle losses power at times. Will not take a charge. It states it is in reduced power mode. It appears to be the becm however my vin is not reported to be on the special coverage.

While driving my Chevy Volt lost power as it disconnected from a full charged battery to gas as the check engine light lit on. The car would then hesitate after stopping at a light/stop sign, losing and regaining power as it gained momentum (which was very dangerous), and would no longer charge. The issue was confirmed by Sun Devil auto repair (diagnosis attached) that this was a known issue with Chevy Volts 2016-2018 and would be covered. I was advised that my VIN was not covered and paid Freeway Chevrolet $2,301.62 (invoice attached with BECM replacement) and would like to be reimbursed. The Chevy Volt's Battery Energy Control Module (BECM) warranty was extended by GM to 15 years or 150,000 miles, from its original 8-year/100,000-mile Volt Component coverage, for 2016-2018 models. This Special Coverage N232432680 addresses potential BECM malfunctions causing reduced power, no start, or no charge conditions. Details of...

My 2017 Chevrolet Volt is experiencing "a malfunction involving the battery energy control module (BECM)" as diagnosed by the Davis-Moore dealership. This failure of the BECM has now caused "a reduced power mode, a no start condition, or a no charge condition". The car currently does not start or charge. My vehicle has be diagnosed as needing a BECM replacement at a Chevrolet dealership. The vehicle is currently inoperable as it will not charge, it will not engage the electric drive mode, and it will not engage the range extender (engine). The car does not start. GM is showing that there is no active recall or special warranty for my vehicle, however, I believe special warranty N23243268 should apply.

I am writing regarding my Chevrolet Volt, which suffered the very common Battery Energy Control Module (BECM) failure that your office already investigated and which resulted in GM being required to extend coverage under special warranty reference: MC-10251431-0001 . Despite this, Chevrolet is refusing to cover my repair. Their reasoning: because my Volt was originally purchased in California, they claim it falls under CARB rules—but now that I live in Arizona, they insist neither California’s coverage nor the NHTSA-ordered special coverage applies. In effect, my vehicle has been trapped in a paperwork loophole GM is exploiting to avoid responsibility. This response is not in the spirit of your findings. The defect was not caused by geography, state lines, or ownership history. The BECM is a manufacturer defect, and it failed for the same reason thousands of others have failed: poor design and inadequate durability. Whether the car was first sold...

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.

The contact owns a 2017 Chevrolet Volt. The contact stated while attempting to turn off the vehicle, the vehicle failed to respond as needed while shifted into park(P). The contact manipulated the gear shifter until park(P) was recognized and the vehicle turned off. No warning light was illuminated. The contact stated that an appointment with the dealer was scheduled to inspect the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 114,000.

Vehicle: 2017 Chevrolet Volt Purchased: March 2017, new from Quality Chevrolet, Escondido, CA I am reporting a persistent and worsening issue with the “Shift to Park” system in my 2017 Chevy Volt. The problem began approximately three months after purchase (mid-2017) and has continued to worsen over time. Initially, the issue occurred intermittently, but it now happens every time I attempt to turn off the vehicle. The vehicle fails to recognize that it is in Park, displaying a “Shift to Park” message on the dashboard even when the gear selector is correctly positioned. This prevents the car from shutting off properly and poses a safety and battery drain risk. I brought the vehicle to Quality Chevrolet for service on the following dates: June 2017 April 2018 August 2020 Despite these visits, the dealership failed to diagnose or resolve the issue. On July 9, 2025, I returned to the same dealership,...

The contact owns a 2017 Chevrolet Volt. The contact stated that after arriving at the destination and moving the shifter into park(P), the message "Shift to Park" was displayed. The contact became aware that with the message displayed the vehicle would not start. The contact disconnected and reconnected the 12-Volt battery to reset the system, enabling the vehicle to start. The contact stated that after starting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the Battery Energy Control Module. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 96,000.

My experience required me to tow my 2017 Chevy Volt from a parking garage, where the BECM died, to 2 different dealerships back and forth to my home. I have been charged over $1,000 in towing and diagnostics at my local dealerships. As usual they informed that I need a new $10k battery. I did my own research and the error codes (U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623, U2624 and P1E00) clearly indicate that my BECM failed. I was able to check the health and status of the traction battery and it functioning correctly. On my 3rd trip to my local dealership service department with the Special Coverage Program N232432680 in hand, the dealership informed me that yes my BCM had failed and there was a Special Coverage Program for 2016-2019 Chevy Volts, but that MY VIN NUMBER WAS NOT COVERED. There were a limited...

The contact owns a 2017 Chevrolet Volt. The contact stated that upon arriving to his destination and moving the shift lever into park(P), the warning message " Shift to Park" was displayed, preventing the vehicle from turning off. There was no warning light illuminated. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who diagnosed a failure with the gear position sensor. The vehicle was not repaired. After investigating the failure, the contact related the failure to Technical Service Bulletin: 19-NA-206. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 85,000.

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.

There is a part that fails on a lot of GM vehicles due to getting clogged (an EGR valve). It prevents the vehicle from reaching high speeds on the highway and can fail while driving (which happened to me). I could have lost control of the vehicle on the highway and crashed or gotten rear-ended. GM refuses to pay for repairs involving this part despite so many people reporting the issue that they needed to do another production run of the part after discontinuing it. Here are many others that experienced this problem: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Chevrolet Volt. The contact stated while the vehicle was parked, the message "Shift to park" was displayed, and the vehicle failed to turn off. The vehicle was taken to the dealer, where it was diagnosed that the gear shifter had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 81,000.

The contact owns a 2017 Chevrolet Volt. The contact stated that occasionally, while attempting to park the vehicle, the vehicle failed to recognize that the gear shifter was in park(P). The message “Shift to Park” was displayed, and the contact was unable to turn off the vehicle during the failure. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the gear shifter was faulty and needed to be replaced. The vehicle was not repaired. The contact referenced Technical Service Bulletin: 19-NA-206; as a possible cause for the failure. The manufacturer was notified of the failure. The approximate failure mileage was 46,000.

I will turn my car on and drive my car and then I will place the car into park and turn off the vehicle as soon as that is done a error message pops up and states that I need to shift to park, but it is in park, and I have to move up the gear shifter slightly and the car turns completely off.

Vehicle slows at times and provides message "Propulsion Power Reduced." At times vehicle will not start and cannot move transmission shifter out of Park.

The contact owns a 2017 Chevrolet Volt. The contact stated that upon arriving to the destination and moving the gear shifter into park(P), the vehicle failed to turn off. The contact stated that the message "Please Shift to Park" was displayed. The contact became aware that the gear shifter failed to return to drive(D). After several attempts over 40 minutes, the vehicle returned to normal functionality. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the gear shifter assembly. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 24,000.

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.

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.

While operating my Chevy Volt on a Los Angeles Freeway, warning lights came on informing me to park immediately, and that the power propulsion was reduced. The Check Engine light also came on. At that point the “Shift to Park” message came on. My car is experiencing the “Shift to Park” issue. I already had this happen previously in 2023. The repair cost $1,200. There are many, many references to this issue on the Internet. The “Shift to Park” defect is well known in the Chevy Volt community. When this happened the SECOND time, ([XXX]), I was stranded on the side of an LA freeway. The car will not start. It will cycle through the “Shift to Park” message on the dashboard and it will not go anywhere. The car initializes, so there is power in the vehicle, but no propulsion.

Just purchased and not a week in it dies after I have charged it. I was in drive, at a red light when all of a sudden the car dies. No warning whatsoever. Was not able to turn it on afterwards. Had to get towed to my local Chevrolet dealership that has not been able to fix it for the last month with no ETA on a fix.

Vehicle began exhibiting issues with BECM, reduced propulsion/limp home mode with range-extender activation. Car unexpectedly stopped running in the middle of the road, came to a complete stop and unable to move off road under car's propulsion.

Purchased the '17 Chevy Volt for my Daughter on [XXX] with 58,867 miles. On [XXX], 60,600 miles; She was driving on the interstate when the engine temperature spiked, followed by a check engine light and a warning message: "Engine unavailable." The vehicle suddenly lost power when she reduced pressure on the accelerator, causing a rapid reduction in speed. nearly causing her to lose control. The vehicle's OBD Codes were scanned at a nearby auto parts store resulting in 30 DTC appearing. I found hundreds of complaints and posts about the F3UA fuse blown and a faulty EGR valve. A service bulletin for this issue was published by GM in Feb 2023. I notified the dealership of the issues and the vehicle was brought to Deacon Jones Chevy of Clinton, NC on July 16th. The service department informed me that the 12V Battery was bad and needed replacement to "correct" the...

EGR valve/cooler fails and makes engine coolant temperature climb above normal operation, leaving you stranded on the side of the road (engine shuts down). I still had battery miles available to pull to the side safely. This is a common issue for these vehicles and GM has not issued a recall or warranty extension for this item like the BECM issue.

While driving, a warning message came on: "Engine unavailable." I was able to drive a few more blocks but then the car stopped on its own. This happened despite the fact that the car had almost a full tank of gas. If this had happened on the highway, it would have been very dangerous. Luckily, I was on a fairly empty city street and I simply pulled to the curb. This is a known problem with the Chevy Volt (2017). An independent service center confirmed that the original problem is that the EGR valve needs replacing. When this is an issue, a fuse often blows and this fuse stops the car from moving. The vehicle has not been inspected by the manufacturer, police, insurance rep or others. There was a message that came on a few days before the incident that said "propulsion power is reduced." An independent service center...

While making a 90 mile drive on 7/20, after having depleted the primary battery charge and switched to hybrid mode, a "propulsion power is reduced" warning appeared on the console, along with the Check Engine Light. Other than somewhat reduced power (max displayed of ~40-50 kW), performance otherwise seemed unimpeded. Contacted local dealership to schedule service for earliest available date of 7/26. Car made return 90 mile trip on 7/21 without issue additional issue ("propulsion power is reduced" message remained.) Service identified "numerous codes", but replaced a fuse known to result in the above issue and observed no other issues. Car was driven purely on battery at that time, and for the intervening time until a 170 mile drive on 8/2, where the message and Check Engine Light reappeared, again after battery charge was consumed and car switched to hybrid power mode. Dealership was again contacted to schedule service, slated...

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.

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.

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.

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 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...

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.

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...
