general problems of the 2017 Chevrolet Volt - part 1

Becm failure. My car is available for inspection upon request. This car has unexpectedly stopped adequately accelerating all of a sudden while on the road! this problems has been confirmed by the dealership. The manufacturer has not inspected it. Not much warning. I found out some not all Chevrolet Volt 2017 users got their becm replaced without cost because it is a well known issue with the car. Chevrolet did not provide extended warranty for all Chevrolet Volt users even though it is an issue with most Volts. I do drive much. I got the car when it was brand new and in 8 years accumulated 77k miles. If I had known all of the cars would have had this safety issue I would not have bought the car in the first place. Chevrolet expects me to pay 2500 out of pocket for something they know is faulty and dangerous in their vehicles.

Failure of battery energy control module (becm), within the high Voltage battery. Vehicle is unable to charge and sets “reduced power” message. Gm released special coverage bulletin for this issue (n232432680), but this vehicle is not listed due to which state it was registered. Continued failure of the becm will lead to inoperability of the vehicle.

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, 2024, the check engine light illuminated again, and on February 12th, 2024, November 25th, 2025, January 11th, 2026, and February 12, 2026 while driving to work, both times I experienced a loss of propulsion power on the highway, placing my safety at risk and lost all power in a traveling lane of traffic. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. The reduced propulsion power while driving on the highway, coupled with the illumination, I urge the national highway traffic safety administration (NHTSA) to investigate this matter thoroughly to ensure the safety of chevy Volt drivers and passengers. It is imperative that general motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

Three separate high-voltage battery section failures within one year, each causing complete loss of propulsion. Two occurred at freeway speeds on [xxx]. Failure 1 ([xxx]): vehicle lost propulsion. Dealer diagnosed dtc p0afa (low Voltage), failed cell in battery section 3. Section 3 replaced under gm special coverage n232432680 (becm, 15yr/150k). Vehicle out of service approximately six months awaiting gm authorization and parts. Failure 2 ([xxx]): vehicle lost propulsion on [xxx] at night at freeway speeds. Required towing. Dealer diagnosed dtc p0afa, cell 85 at 1. 85v in battery section 1 (different section). Section 1 replaced under same special coverage. Vehicle returned Jan 28, 2026. Failure 3 ([xxx], ~300 miles after failure 2 repair): vehicle again lost propulsion on the freeway with check engine light, then progressed to no-start condition. Towed to dealer. Diagnosed Feb 20, 2026: dtc p0afa, cell 57 at 1. 5v in battery section 2 (gm minimum spec 2. 5v). Third distinct section failure. Vehicle remains at dealer awaiting gm repair authorization as of filing date. Safety concern: loss of propulsion at freeway speeds is an immediate safety hazard. During the Nov 2025 event, the vehicle lost power on [xxx] at night in active traffic. The progressive failure pattern (three different sections failing sequentially in the same pack, identical dtc) suggests a systemic defect rather than isolated component failures. Prior section replacements have not resolved the underlying problem. Vehicle has been usable approximately 20 total days in the past 12 months. All repairs performed or pending under gm special coverage n232432680. Gm case [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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?.

Following a day trip involving sub-freezing temperatures and full depletion of the traction battery, the vehicle was plugged in at home and appeared to be charging. The following morning, I enable the preheat via the remote before leaving the house for work, and notice the cel/mil before starting the car. Car was cold, charging indicator was flashing green as if it was accepting charge. I went to investigate and was met with the following list of codes: p1e00, u2603, u2604-u2606, u2617-u2624, p1fd2, p1fd3, p3042, c326c, p0096. Car turns on but seems to only be accessories; no power steering. Seems like the state of charge indication kept transitioning from empty to full. I unplugged the car to see if it could still drive, but no luck. Getting "shift to park" when I put it in drive. Switching to hold does not engage the engine. After plugging it in again, the car no longer receives charge and simply holds the orange charge indicator light. In an attempt to get the car into limp mode, I tried clearing the codes, but no luck. After reading the codes again in the afternoon, the following codes posted: p1e00, u2622, u2623, p1fd4, p0afa. These codes and behavior are consistent with the following ntsb service documents, which call for the replacement of the becm: special coverage n232432680 technical service bulletin 18-na-261 however, the vehicle in question does not appear to be one of the 19,000 vehicles covered under the special coverage, per gm’s warranty look-up. The vehicle has not yet been serviced for the above events, but it is assumed the becm is failing, which is available for inspection. My safety was not put at risk this time, but it is possible for the becm to fail in an unsafe manner. Additionally, the associated repairs are costly since the becm is not easily accessible, requiring lifting the car and removing the entire traction battery.

My 2017 chevy Volt stalled, wont charge, safely concerns. Safety-related special coverage is being denied by local chevy dealer. Check engine light codes u2603-06, u2623, well known issue in chevy Volt community, that points to chevy faulty becm. Chevy replace these to some selected 2016-2018 vehicles, but they wont cover mine, while I have same exact issue. Please help to push on chevy to cover all 2016-2018 chevy Volt by recalls repairs with no cost to owner. Thanks.

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 shifter had been replaced (or repaired?) for an earlier shift to park failure per TSB 23-na-119. The dealer kept the becm as a core. I have pictures of the core. The dealer or gm should have that core. The above described warning lamps and messages and systems first appeared at the time of the event that lead me to take it other dealer ASAP. Note the condition and model year is described in gm special coverage letter "n232432680 battery energy control module malfunction". Nhtsa investigation pe23022 lead to this coverage letter. Per gm, while my vehicle experienced the conditions and is in the model year coverage of the letter, its VIN is not covered. I think NHTSA should re-open the investigation and consider a recall. There could be other vins susceptible this failure condition. There could be operators of those vins who cannot afford the expense (~$3000 or more) or downtime of the repair, and will keep operating the vehicle, putting people at risk again. If a recall is not supportable, I'd request that the VIN list be expanded to cover all possible defective becms.

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 contact owns a 2017 Chevrolet Volt d2. The contact stated that while attempting to turn the vehicle on the vehicle did not start. The contact stated that vehicle restarted after an hour. The contact stated the during the second occasion the vehicle did not restart. The vehicle was towed to a dealer where it was diagnosed that the battery energy control module needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was approximately 75,000.

The high-voltage heater control module (also known as the ptc coolant heater / k10 heater module) has failed. This component controls cabin heat and windshield defrost when the vehicle operates in electric mode. The authorized Chevrolet dealer diagnosed the issue, confirmed the failure, and attempted to order the correct gm part. Gm informed the dealer that the part is no longer manufactured or available through gm channels. As a result, there is currently no gm-approved repair path. This failure prevents the vehicle from providing windshield defrost while operating in ev mode, which is required for safe winter visibility. I live in new hampshire, where winter temperatures routinely require functioning cabin heat and defrost for safe operation and compliance with state visibility laws. Because this is a high-voltage thermal management component, there is no safe aftermarket repair option. The inability to obtain an oem replacement part for a safety-related system prevents the vehicle from operating safely in intended ev mode.

The becm failed, engine light on, car is at reduced power or doesn't run at all. A message states that there are no ev miles available when it is full to to place the shifter into park. There is a free extended warranty for it (xxx- special coverage--battery energy control module malfunction - ) but my Chevrolet dealership in wenatchee, washington says that it's not covered. I want to know why they said this. I have been stranded without an operable car, unable to get to and from work. If I don't go to work, I can't pay my mortgage. I don't have another car to drive or the means to rent one. It needs to be towed 90 miles to a dealership which that price will be astronomical on my poverty level income. I have cancer and need to get to my treatments. The cost to replace the becm is $2100-$3000 out of pocket not including towing. The error code was read as a failed becm by a diagnostic reader and it's having all the symptoms of a failed becm. It has the following code: p1e00 $07e8pd initial symptoms in the prior week before the car wouldn't operate, was that I got a message to put the car into park when it was already in park. Sometimes the display wouldn't work. Sometimes the heater wouldn't turn on in the preceding 2 months. Global safety field investigations dcs6812 urgent - distribute immediately reads that 2016-2018 Chevrolet Volt models are covered. I've attached this letter.

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 car failed again due to the dealership not correctly diagnosing the issue, which appears to be the becm, a failure related to bulletin n232432680. Due to this issue, I was left stranded on a busy highway for several hours on multiple occasions, and have not have a working vehicle since 10/14, meaning I have had to call off of work on multiple days, losing non-trivial amounts of income and undue economic hardship, due to this issue. Neither the dealership nor general motors have offered any kind of help or support, and have generally attempted to avoid responding to my repeated phonecalls. Prior to this issue, there were no warnings or symptoms that I observed.

Approximately 3. 5 weeks ago my 2017 Chevrolet Volt (105k miles) would not start and then, when it did, was in "reduced power mode". I had to drive home 25+ miles in this low power mode. I brought to my local mechanic (not a Chevrolet dealership) first. They did a diagnostic and told me the issue was "battery energy control module" - a known issue in 2016-2018 Chevrolet Volts affecting 19,000 vehicles for Chevrolet provided extended warranty coverage for up to 15 years/150,000 miles. See special coverage n232432680. I was not able to get an appointment for 9 days at the Chevrolet dealership in oxford PA. The vehicle needed to be towed there because it wouldn't start. Chevrolet dealership said it was not the battery energy control module but rather the 12v battery. They replaced battery, I picked up vehicle and paid $525+ for diagnostic and new battery. By the next day, the vehicle wouldn't start again. I brought the vehicle back and they did diagnostic again and this time determined it was the battery energy control module. Dealership said Chevrolet has not included your VIN in the special coverage and didn't know why not. I called Chevrolet/gm customer service (800-222-1020) and spoke with two people including an escalation supervisor and both said the VIN for my vehicle was not included because it was determined that would not be part of the special coverage they've offered. We went round and round and no one will give an answer as to why there is a known issue for 2016-2018 Chevrolet Volts yet my vehicle is being excluded. They said they have no ability to change it and include it in the special coverage. If months or years down the road, they determine it should have been included then they'll reimburse me. That answer is unacceptable. Between repairs, initial misdiagnoses and repair and rental car fees, I'm out over $5,000.

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 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.

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.

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.

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.

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 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 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 number of vins that received warranty extensions for becm, but mine was not.

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.

More than two weeks ago, my 2017 Chevrolet Volt lt showed becm codes. The local dealership service center said they would order the parts for a complete replacement. 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 11517042. The warranty coverage number from Chevrolet's bulletin in regards to this failure n232432680.

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.

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.

The contact owns a 2017 Chevrolet Volt. The contact stated while the vehicle was parked, the vehicle stalled; the contact stated that the vehicle was jumpstarted and the vehicle to returned to normal operation; however, the failure reoccurred on several occasions. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the battery energy control module (becm) needed to be replaced. The vehicle was not repaired. The vehicle was towed to a dealer where it was diagnosed that the 12-volt battery needed to be replaced. The vehicle was repaired; however, the check engine warning light illuminated again. The manufacturer was not notified of the failure. The failure mileage was approximately 107,000.

Vehicle slows at times and provides message "propulsion power reduced. " at times vehicle will not start and cannot move transmission shifter out of park.

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.

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!!.

Dear NHTSA officer, I am writing to report a serious safety incident involving my 2017 Chevrolet Volt. On November 9, 2024, while driving with my family, our vehicle unexpectedly lost power without any warning. The details of the incident are as follows: incident: the car powered off suddenly. Passengers: myself, my wife, and our two children were in the vehicle. Aftermath: we were unable to restart the car despite multiple attempts. Resolution: it took two hours and assistance from neighbors to push the car back to our driveway. Upon researching this issue, I discovered that other 2017 Chevrolet Volt owners have reported similar symptoms, which appear to be related to battery energy control module (becm) failures. Furthermore, I found that gm issued technical service bulletin (TSB) 18-na-261 addressing "an internal issue within the battery energy control module" for Volt models. This incident has raised serious concerns about the safety and reliability of our vehicle. I am requesting immediate attention to this matter, including: a thorough inspection and repair of our vehicle information on any recalls or extended warranties related to this issue assurance of the vehicle's safety for future use given the potential danger posed by sudden power loss while driving, I believe this issue warrants urgent attention and possibly a wider recall. Thank you for your prompt attention to this critical safety matter. I look forward to your timely response and resolution. Sincerely,.

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.
