2017 CHEVROLET VOLT

FUEL/PROPULSION SYSTEM

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 the freeway I might not have been able to make it to the shoulder potentially putting myself and others on the road and a possibly fatal situation.

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 in California, Colorado, or Kansas is irrelevant—the failure is GM’s, and the repair obligation should be GM’s as well. By denying coverage on a technicality, Chevrolet is undermining the very purpose of the extended coverage you required: to protect owners from footing the bill for a well-documented, widespread, and unsafe defect. Their position leaves me, and others like me, bearing the costs of GM’s engineering failure. I ask that NHTSA review GM’s handling of these claims and require them to honor the extended coverage as intended, without hiding behind jurisdictional loopholes.

FUEL/PROPULSION SYSTEM

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

ENGINE

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 year. Fortunately for me, even though the CEL came on for the reduced propulsion I was able to reach my destination. However, when I went to leave, the car left me stranded as the ICE would shut down after a few minutes of running. The propulsion system is reduced and the engine becomes unavailable. Only the battery power will allow the car to drive. The F3 fuse in the EGR circuit blows if the engine is activated, and has happened multiple times already confirming the EGR issue. I have additional check engine lights that are a result of the EGR failure to circulate coolant properly. Below is a list of all the CEL codes that were pulled: P06DB P0030 P0031 P0403 P0405 P0443 P0458 P0489 P0597 P0598 P06DA P0AC4 P0135 P0AC4 P16E0 Looking into this issue I found that this is an one of the most common failures in the Chevy Volts but is no longer covered under the vehicle warranty and no bulletins posted for an extended warranty other than the BECM failure. This failure is so prevalent that I am surprised it is not.

VEHICLE SPEED CONTROL

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.

SEAT BELTS

Component or System Involved: The rear passenger-side seatbelt (right side from the driver’s view) on my 2017 Chevy Volt Premier malfunctioned. Specifically, the automatic locking retractor (ALR) mechanism failed and would not release tension, even after fully retracting the strap. The cut portion of the seatbelt is still in my possession and can be made available for inspection upon request. Safety Risk: This failure posed a serious safety risk. The seatbelt had been secured around a child car seat base, and once it locked, it would not release. After more than 30 minutes of troubleshooting — including fully retracting the belt and manually pressing the emergency release button inside the seat — it still would not disengage. The car seat base could not be repositioned or removed safely, which would have compromised the proper installation of a child safety seat. With no other option to ensure safe transport, I was forced to cut the seatbelt free. The problem has not yet been reproduced or officially diagnosed by a dealer or independent service center. I have not yet reported it to GM or visited a dealership, but I plan to do so soon. The component has not been inspected by the manufacturer, police, or insurance representatives at this time. However, this closely mirrors recall 18V673000, especially since that recall affected Volt models 2018-2019 and mine is a 2017. There were no warning lamps, dashboard messages, or advance symptoms before the failure occurred. The seatbelt functioned normally until it was engaged with the car seat, at which point the retractor locked and failed to release.

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, and they finally diagnosed the problem as a faulty jumper harness and switch contact, quoting $586 plus tax for the repair. I requested a goodwill repair from GM, given that the issue began within the warranty period and has been ongoing for years, but my request was denied. This is a known and widespread issue affecting many GM vehicles, and I believe it represents a design or manufacturing defect that should be subject to a recall or broader investigation. I am requesting that NHTSA investigate this issue further to ensure consumer safety and accountability.

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 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 number of VINS that received warranty extensions for BECM, but mine was not.

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 push it out of traffic. I turned on my hazard lights and a person came out from his house to assist in directing traffic away from my car for about an hour while I waited for a tow truck to arrive. The kind bystander who directed traffic and I were very concerned about a car accident happening due to my stopped vehicle. A police officer stopped by to check on us and try and get my vehicle into neutral but he was unable and said he was on his way to a 911 dispatch so he did not write a report of any kind that I could see. He told me the vehicle placement was not safe and I agreed with him. The tow truck came as he was leaving. The dealership I sent my car to said it is likely a short circuit in the 12v battery but I know the BECM in the Chevy Volt is known to cause similar behavior. Dealership refused to service the BECM when asked about it.

My 2017 Volt reported a "Propulsion Power is Reduced" message on the display. When I took the car to the dealership for service, they stated that a new EGR valve was needed. The part alone is $1847. The total service with labor would have been over $3000. Looking online, it is a very common issue for the gen 2 Volts. Unfortunately, the dealership is saying this repair is not covered under warranty.

The work and parts are covered under warranty as this has been a common issue. The BECM and coolant arrived within a few days, but the remaining parts are back ordered! After two weeks of waiting GM has failed to send the parts and I and my family are in need of our vehicle for both work and safety reasons. The part number for the parts that still need to be sent is: 11517042. The warranty coverage number from Chevrolet's bulletin in regards to this failure is: N232432680.

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)

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 fix the HPCM2 software bug. After I told them that the maintenance items were complete, they called me back an hour later to tell me I needed other maintenance repairs that are less common. When I gave them the description of the recall and re-explained this is identical to my car's symptoms and that this manufacturing issue may have affected other vehicles like mine that were outside of the recall batch, they told me it was impossible to apply this diagnosis as long as my VIN number was outside of the recall batch. Can you please add my VIN to this recall or have my car reviewed by someone who can debug the software?

I am submitting this complaint regarding a recurring and potentially hazardous issue in my Chevrolet Volt 2017.The vehicle frequently displays a “Shift to Park” warning message even when the gear shifter is correctly in the Park position. This malfunction prevents the car from shutting off properly, posing both safety and operational concerns. This issue is widely reported among Chevrolet Volt owners, and General Motors has acknowledged it in Technical Service Bulletin (TSB 19-NA-206). Despite this, no formal recall has been issued to ensure a permanent solution for affected drivers. My Volt currently has 138000miles, and although it is outside of the Voltec Warranty period, this is clearly a manufacturer defect—not a result of normal wear and tear. The problem affects the safe operation of the vehicle and may lead to battery drain, inability to power down the car, and driver confusion. I strongly urge the National Highway Traffic Safety Administration (NHTSA) to investigate this issue and consider initiating a recall to protect drivers and ensure accountability. Thank you for your time and attention to this matter.

FUEL/PROPULSION SYSTEM

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.

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.

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 the nature of the EGR Valve blowing the fuse all the time and that it affects the safety of the vehicle a nationwide recall needs to be done on these vehicles to force GM to start making the part again. This is a dangerous flaw that will cause the vehicle to stall and create a safety hazard. This has been ongoing for quite some time with these Volts, and something needs to be done about it ASAP.

When moving the shifter to the "P" position after parking, the car will refuse to turn off with the message on the dash: "Action Needed: Shift to Park". Shifter is in Park position but car will not recognize this and does not turn off. The issue can sometimes be resolved by pressing the shifter knob button repeatedly, or by pulling the shifter all the way back to drive and forth to park multiple times until the message is cleared. This happens about 4/10 times that I drive, There is currently a bulletin posted by Chevy for a fix. However, the fix is only covered under a "warranty" and the Chevy repair center at the dealership quoted $400 to complete the repair out of warranty.

I am lodging a complaint about General Motors in dealing with a warranty repair to my 2017 Chevrolet Volt. On 9/11/2024 had low propulsion warning and took the vehicle to a local dealer. I though it may have been the power module, but the Dealer stated: “The module would not be replaced because it is not failing. Your high voltage battery is made up of multiple sections that control the power of the vehicle, one of those sections of your battery has a failure so rather than replacing the whole high voltage battery, GM will usually authorize replacement of the failed section.” On 9/13 GM authorized replacement. Weeks passed and I was told the battery section would come Q4 (2024]. The dealer has been very responsive about keeping me with loaner vehicles. I have issues only with GM. I asked GM to buy back the vehicle in January 2025. The request was verbally denied since for some undisclosed reason it does not fall within the California Lemon Law parameters. Later I was told by GM the part is expected “Q2”. GM has a representative call em every week or so just to check in. This was a safety issue as the car went to low power and might have caused significant problems in traffic. All the while I have been unable to drive the car, sell the car, or otherwise enjoy freedom of ownership. Now we are looking at at least 6 months in the shop, potentially 7-9 months or more. This is an unreasonable timeframe for repairs and hence this complaint. Please advise how I might proceed from this point to get the matter resolved soon.

Battery Energy Control Module failed and left my daughter stranded.

Yes this vehicle can be made ready for inspection upon request. According to the registered Chevrolet dealership who inspected my vehicle and gave me the diagnosis - The cars EGR valve control board is shorting out Fuse #3 which leads the car to enter “reduced propulsion mode” and keeps you from using the generator engine due to being in this mode. This happened as I was driving home from work one day and the car notified me of this issue and entering into this mode. This could leave people stranded if low on battery charge, or in danger due to reduced propulsion. Chevy no longer manufactures this unique EGR valve and thus the repair requires obtaining back ordered parts from a manufacturer outside of the US for thousands of dollars. Alternatively you can drive without the EGR power cord connected, which means greater emissions and environmental risk/damage. This is not covered under warranty. This is a known faulty part that many Volt owners complain about, which makes it a good candidate for recall.

The car has a Check Engine Light and "reduced propulsion" warning. Based on OBDII errors, the EGR on my chevy volt failed. I am not in a CARB state (i'm in Hawaii, though I bought my Volt in CA, which is a CARB state). The EGR issues plague all Gen2 Chevy Volts, and tends to break around 40-70k miles into the life of the car. EGR spare part availability is very limited. Given the frequency with which this car breaks for this issue, and the negative impact on emissions, this should be a recall issue nationwide, not just for states that keep CARB requirements.

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 to start the parked car. I had the 12V battery replaced as the local mechanic where it was towed thought that that might be the cause.) I turned the car off and back on and when I tried to shift to D or R the dash stated "Return to P" AAA made us a priority tow as we were on a major thoroughfare. We were at risk, but thankfully we were relatively safe. I called GM to say that it seemed that the EV battery had died suddenly. I was advised to bring it to the dealer. I called the dealer and they quoted me the cost of replacing the EV battery. They mentioned nothing of National Highway Traffic Safety Administration investigation into the model year 2016 through 2019 Chevrolet Volt amid complaints about the hybrid’s battery energy control module, or BECM, some of the complaints indicating that drivers had little to no warning before the car lost operating power or entered reduced power mode, which was exactly what had happened to me.

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!!

FUEL/PROPULSION SYSTEM

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 of motorists.

ENGINE

My car's check engine light went on and after a while started blinking. The car would not go. When I got it towed and checked by the dealership, they said my EGR Valve had an issue and needed to be replaced. They said the part was on backorder and it could take months and tried to charge me $2,000 up front to "reserve the part." It seems like GM has deprioritized this part and is putting drivers like myself at risk of not being able to use our cars and not being able to pass emissions inspections required in my state. This was originally diagnosed in spring 2024 and I have been unable to get a replacement as of January 2025

UNKNOWN OR OTHER

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.
