2018 Chevrolet Volt complaints

The contact owns a 2018 Chevrolet Volt. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the EVAP pipe was rubbing against the air conditioning hose connector. The dealer informed the contact that the vehicle was previously repaired under GM Campaign Number: N192273600; however, the failure persisted. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 84,800.

EGR valve clogged and failed on a long trip, bricked the car and had to tow many miles back to home shop. now have been waiting 9 months and still no idea when the part will be available from Chevrolet. My shop and I have claims to Chevrolet for the part for service but still nothing and is getting so we are inconvenienced in travel.

Randomly getting Propulsion power is reduced and loss power while driving. Been force to pull over to the side on the freeway to restart the car.

The contact owns a 2018 Chevrolet Volt. The contact stated that while the vehicle was parked and shifted to park(P), the message "Shift to Park" was displayed on the instrument panel and the vehicle was inoperative. The contact stated that the vehicle was operative while in low power mode; however, the vehicle intermittently failed to charge in low power mode. No warning light was illuminated. However, the vehicle displayed the full battery icon on the display, but 1 EV Mile. The vehicle was taken to an independent mechanic where it was diagnosed that the battery energy control module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 11,000.

The BECM (Battery Electric Control Module) failed in November of 2023. Mountain Chevrolet has had my vehicle since then, claiming to be unable to find replacement battery module. The vehicle is available for inspection at Mountain Chevrolet (it has been left unlocked, unprotected, and exposed to the elements for almost 15 months now). When the BECM failed, the vehicle lost virtually all power and slowed dramatically from highway speeds to ~20 mph. There were no warnings prior to the failure.

When putting my car in park and shutting it off the dash board tells me to shift to park, and car does not fully shut off.

The contact owns a 2018 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The check engine warning light illuminated. Shortly afterward, the message "Reduce Propulsion, Engine will not Start" was displayed on the instrument panel. The vehicle was towed to a local dealer where it was diagnosed with a defective EGR valve. The contact was informed that the EGR valve needed to be replaced. The vehicle was not repaired due to the cost and lack of parts availability. The vehicle was towed to the residence. The contact believed that the cause of the failure was related to high temperatures. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

Driving on gas on the highway, the adaptive cruise control suddenly disabled with a "Reduced Propulsion" message on the dash and a check engine light. The car started struggling in its propulsion. We found an AutoZone and scanned the codes, and multiple were returned. A Google search pointed us to the "walk home" fuse, which indeed had been blown. Replacing that fuse and disconnecting/reconnecting the battery eliminated the errors. Less than a week later during highway driving (the next time the battery charge was used up and it switched to the ICE) I got another check engine light, but this time without the "reduced propulsion" message. Scanning at AutoZone again revealed a P0404 message referencing the EGR valve. Due to the limited availability of the part I have called into Covert Bastrop (Bastrop, TX) and am waiting to hear back on their ability to fix the car.

The issue started with a forward push while lowering my speed while coming to a stop. It then progressed to a trembling engine. Then it progressed to the car struggling to effectively switch from electric to gas and back. It then would only be usable on electric range and the engine would not start and would be greyed out. Now, it only works on engine mode, it uses fuel like a pick up truck, it loses power while driving due to trying to switch to electric mode and back, and it struggles to accelerate. It will do it while idle as well as while driving 45mph and up. It barely has any propulsion power and I have to turn my hazards on any time I am going to accelerate. If I brake hard the engine will shake violently and then shut off. I then have to switch gears from drive to park or neutral to park to drive to reengage the engine. Recently it has turned on all the accessories but the ev and the gas is greyed out and there is zero propulsion power. I replaced the 12v battery thinking it might have been dying and it still has the same issue. I read about the class action lawsuit for the BCEM and have made an appointment the dealership but when I told them what was wrong with it the said we need to wait for the diagnostics.

Took my 2018 chey volt to the dealer after trying to start the car and shifting into reverse a Action Required and shift to park massage appears. Towed the car to the Chevy dealership of on 11-19-2024 and on 12-17-2024 after the dealership has been talking with GM they tell me the car needs a new battery pack and there are none to be found. Car is still under GM warranty! Service adviser recommends calling GM to buy back or get a Lemon law Attorney

The contact owns a 2018 Chevrolet Bolt. The contact stated while driving at a moderate speed, the check engine warning light illuminated, and the “Propulsion Power” message was displayed. The contact pulled over and upon an attempting to restart the vehicle, the vehicle failed to restart. Due to the failure, the vehicle was towed to an independent mechanic where it was discovered that the BECM (Battery Engine Control Module) was defective. The mechanic discovered that the vehicle was under warranty and contacted that the local dealer for assistance. The mechanic drove the vehicle to the dealer who acknowledged the failure; however, the dealer stated that the failure was not covered under warranty. The manufacturer was also notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 100,000.

I was driving and a message "engine popuslison reduce" appeared and i was not able to drive at the speed of traffics which was unsafe.

On [XXX], while driving on [XXX] in Virginia, the check engine light came on in my Chevy Volt. A message on dash said that there was reduced propulsion, and the gas engine quit running. The car switched to battery power, which would not have lasted long enough to get us home. At this point, we were stranded on a very busy highway which seemed quite dangerous. Using battery power, we were able to get off the highway. We then made arrangements to have the car towed, approximately 150 miles to a car dealer/repair business in Frederick MD. The vehicle was checked out by the car dealer who identified the EGR valve as the problem. However, they did not know when the part would be available , and still, 4 weeks later, do not have any date for availability of the broken part.

On 9/18/24 I was driving my Chevrolet 2018 Volt on a freeway, traveling at approximately 55 mph while starting to exit the freeway. In the middle of fast-moving traffic, on the freeway offramp and starting to decelerate, the car suddenly displayed a message saying "Propulsion Power is Reduced." A micro-second later, the displayed message changed to read "Action Required: Shift to Park" and in that moment I lost control of the car's powertrain. I continued to break, coming to a slow stop in the middle lane of a multi-lane offramp, with other cars speeding past and around me. I attempted to power the car down and reboot it, moving the gear shift into "Park" position as instructed, but nothing changed. The car remained totally inoperable. I was on a slight decline and noticed the car moving forward pulled by gravity, so I steered the car to the farthest right of the offramp/parallel street, where I put my hazard signals on and requested the car be towed to a mechanic. I was endangered because the car lost entire propulsion while in the middle of fast-moving freeway traffic, and fellow motorists were endangered as well. I have learned that this same behavior occurs routinely with 2nd generation Volts; that there is a special bulletin related to the car's BCEM *and* a related class-action lawsuit posed against GM/Chevrolet. I requested Chevrolet take preemptive action to repair the BCEM, as I am fearful the issue will repeat and cause additional danger to myself and fellow motoris

While driving my vehicle when the outside temperature is 50 degrees Fahrenheit or below I turn my defrost on and for 30 plus seconds my front window completely fogs up and I am unable to see out of my front window and have zero visibility which caused me to crash.

On 8/30/2024 I had driven my 2018 Volt (purchased new on 3/27/2019), with about 45,000 miles on it, on a normally 5 hour trip. About 3 hours into my trip on I-94 my car suddenly slowed down with a "Reduced Propulsion" message and a check engine light that came on. (The engine probably has run less than 25,000 miles of the total miles I have driven it, with the rest being purely on battery.) I was extremely fortunate to have been in the slow lane when the car suddenly stopped accelerating. This could have easily turned out very, very bad. The next day I had a dealer diagnose the car for a little over $400 - they told me there was a problem with my engines EGR valve and that the parts were back ordered so they couldn't give me an indication of when it could be repaired. I got the car back to my home dealer and they charged me another $200 to re-diagnose the problem and came the same conclusion of a bad EGR valve. They too have been unable to get a valve from GM. They have quoted me about $4,000 to have a new valve installed when they can get one. Heck, the car only has 45,000 miles on it!!

While driving our 2018 Chevy Volt, dashboard warning message “Propulsion Power Reduced” displayed. Vehicle performance was not otherwise affected. Subsequent diagnosis from our Chevy Dealer was, among other things, a faulty Exhaust Gas Recirculation (EGR) valve. We were informed that our vehicle was “no longer safe to drive in this condition” and the vehicle has been sitting on the Dealer’s lot awaiting a replacement part for 2 months and counting, with no expectation of near-term resolution of our problem. We are aware that this is a widespread problem on 2017-18 Volt models, with many dissatisfied owners.

Lost power when battery power used up and gas engine would not switch over on highway. car would not re-start and died in the middle of highway

I think this is an EGR or BECM issue. Yes, the car is available for inspection. I plan on calling the local dealership soon. The car loses speed and does not respond to the accelerator. It must be turned off and back on again to function properly. This is very dangerous when it happens in traffic. The check engine light comes on, and a reduced propulsion message has appeared. This has happened several times over the past couple of weeks. Each time, I was driving in normal mode, using electric power. Suddenly, the electric range displayed zero miles left, the gas engine turned on, but the car lost speed and would not respond to the accelerator. I have not had it inspected because I don't know how to force it to replicate. I don't want to pay for the dealership to diagnose a problem they won't find.

The Exhaust Gas Recirculation (EGR) value has failed after only 20,000 miles of engine usage in my hybrid car. This is a highly-common part that fails and when it fails it shuts the engine down while driving; which leaves the driver stranded. General Motors does not have the part available to purchase and has been on backorder for nearly 4 years. They do not have a resolution and they are not recognizing the GM Service Bulletin that was released 21-NA-116 in Feburary 2023. This is unacceptable. The dealership wants thousands of dollars for a $150 part (that you can't purchase).

Car has shift to park error where the shifter is in park but the car not does not recognize and refuses to shut off. Chevrolet has issued multiple service bulletins in regards to fix but dealership is not adhering to bulletin. Chevrolet then provides no support to the consumer in regards to correcting and places warranty information within service bulletin which is not standard procedure as told by multiple reps

I have had 3 separate "Low Propulsion" warnings pop up, in combination with a check engine light, in the last 9 months. Everytime I take it to the dealership, they say it was a same code, and something to do with the oil valve. They repair it, and 3 months later it happens again. Going in for my 4'th repair soon, but I just saw there was a recall issued on the BCEM, but apparently it only applies to certain VINs? I have seen online posts from people saying they had to call GM to get them to approve the recall for their vehicles. Why would it only be certain vins?

Reduced Power/Low Propulsion warning, Check engine light. Car may experience reduced power. Could be hazardous at high speed. Dealer diagnosed vehicle and found bad EGR valve. Part is on back order with consumers waiting months even years for replacement part

Failed EGR Valve. While I was driving, I got a "Propulsion Power Reduced" message and "Engine Unavailable." My car slowly began losing power, leaving me with about 30 seconds to safely pull over. I had it towed to the dealer and they diagnosed a faulty EGR valve. This seems to be a widespread problem with the Chevrolet Volts. To make matters worse, the replacement part is extremely hard to find, with many people waiting on backorder for over a year.

Our Volt EGR valve has gone bad and car not drivable. They claim these have been on back order (very expensive) for a year! They also say it's NOT part of emissions! WTH? Car gas 36k HELP!!

On [XXX] while driving with my son in IN on [XXX] to my niece's wedding in PA, a reduced power warning sounded on the driver's console. Was able to stop and get gas at the eastbound travel plaza near mile marker [XXX]. Getting back on the road and accelerating toward 70 mph, suddenly lost all drive power. The fuel gauge side of the console was lit in yellow and said something like "No fuel detected." Pulled over to the shoulder and found the engine would start, run, and then die. An IN State Police Officer was kind enough to offer us an escort to the next exit near mile marker [XXX]. Noticed that the engine would remain running for longer periods and finally stayed on continuously. While being escorted, was able to run the speed up to 55 mph and made it safely to the interstate exit. During this time my son was checking online and found that the problem might be due a blown fuse. At the [XXX] exit we found a Pilot station that carried fuse sets. One of the sets had the fuse we needed. We bought two sets. We replaced the fuse--it had blown--and the car ran well again. This fuse is called "No walk home." We were able to continue on at 70 mph until stopping at a friends home in western PA for a few hours rest. While at our friend's home we partially charged the Volt's battery giving us about 20 miles of electric range. While in electric mode we stopped for gas. We drove through the mountains without incident then stopped for gas again in central PA at the Cumberland Valley Servi

The contact owns a 2018 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the message "Engine Not Available" was displayed and the vehicle stalled. The vehicle was not able to be restarted and was towed to a local dealer where a reset of the engine code was performed. The contact stated that the failure reoccurred, and the vehicle hesitated while accelerating. The contact was able to pull the vehicle to the side of the road, and the vehicle was towed to the local dealer where it was advised that the battery of the engine control module needed to be replaced. The vehicle was not repaired. The contact related the failure with the Technical Service Bulletin: 18-NA-261 (Malfunction Indicator Lamp Illuminated and/or Intermittent No Start with Battery Circuit DTCs Set); however, the vehicle was not included. The manufacturer was made aware of the failure; however, no assistance was provided. The failure mileage was approximately 150,000.

Shift to park issue. Known issue with 2018 Volts but dealer is charging diagnostic fee when they know it is the issue because it displays shift to park when you try to shut car off. There is a bulletin stating this 19-NA-206. It states the Voltec warranty covers this but dealer states it is not. Dealer is West Herr Chevy, East Syracuse. Had to wait two weeks with the problem and then they left me stranded at the dealer ship because they did not fix it. This dealer had computer issues and sent service home early and left me without a ride home when I returned. GM needs to notify these dealerships that this problem is covered.

While driving on the highway, the EGR valve in my car malfunctioned, initially causing my dashboard to read "Propulsion Power is Reduced". After continuing to drive the car, the dashboard read 'Engine not available, service soon', where it stalled and we had to restart the car. After restarting, the car went into EV mode with significantly reduced speed. Our safety was put at risk due to the initial stalling and subsequent reduced speed on the highway. The problem has been reproduced since the initial incident and our dealership confirmed the problem relating to the EGR valve which continues to blow fuses when the engine is over-exerted while using gas. The dealership said that this is covered under warranty however, there has been a 5-year back-order on the part and they are refusing to offer any loaner car or compensation for a rental car.

The contact owns a 2018 Chevrolet. The contact stated that on several occasions while driving at various speeds, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was steered to the side of the road and restarted each time, but the failure persisted. The vehicle was taken to the dealer where it was diagnosed that the EGR valve needed to be replaced and 40 unknown DTC codes had been retrieved. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 55,000.

When attempting to power down car after shifting into park, message states shift to park. Car cannot be locked or secured.

While driving in August 2023, the vehicle seemed to lose acceleration power and a warning regarding the reduced propulsion appeared. The vehicle was taken in to the dealership and the diagnosis was that the EGR valve needed to be replaced. Still waiting on the issue to be resolved as GM doesn't seem to have the part required to fix the problem.

The "module" that controls the engine's charging of the battery failed and the car quickly went into reduced power mode and then quickly shut down altogether this happened within a mile or so. Fortunately this happened on a parkway where I could get to the curb safely. However, I had just come off [XXX] in St. Louis with very heavy 65 MPH traffic, and had it shut down a few miles earlier I would have been in real trouble. I understand the NHTSA has opened an investigation into this type of problem with the Volt, but I have also heard that G M is reporting they have the parts to fix cars that are affected. This is not true! I live in Lenexa, KS, and my Volt is at ELCO Chevrolet in Baldwin MO. The service representative told me on [XXX] the part I need is "on backorder" and he has no idea when the part might be supplied to him. Apparently, GM does not have this part anywhere in the world, a part without which the car will not move. This is inexcusable!

My 2018 Chevy Volt displayed a warning message of "Propulsion Power is Reduced" on the dash when I started the car in a parking garage on Saturday, March 9th around 10am. The car would not drive normally and made a strange noise. I had to stop and start the car six or so times before it drove normally for me to get home. Had this happened at high speed, it could have caused an accident or worse. I contacted the local Rockville, MD Chevrolet dealership and they ran the diagnostic test on the BECM and HPCM2 systems and performed battery capacity reset. I do not believe this software reset will correct the technical issue. According to the dealership records, such a software reset was performed in 2021 by the previous owner before we purchased the car second hand in July, 2022. The dealer would not replace the BECM unit but there is supposedly a special coverage bulletin issued by General Motors. We need the unit replaced ASAP for safety.

Ten mile trip with 60% battery charge (about 30 mile range indicated, full tank of gas). Check engine light appeared. "Propulsion Power Reduced" appeared and cleared after restart at traffic light. Total loss of power at highway speed, "Shift to Park" appeared. "Power Off" appeared on energy display, coasted to shoulder and was unable to restart vehicle after multiple attempts.

While driving, an engine warning "Reduced propulsion Message" came on. Then it said " Engine Unavailable". The car would not go to gas engine. We panicked as we were 20mi from home and only had a few miles of electric left. I was able to drive to the nearest Chevrolet Dealership. It has been sitting there parked for 2 months. Uncharged. We are told that the problem is the EGR valve but no part is available anywhere. It is a known problem but GM has no parts available to fix. I am not getting any answer as to how long it may take to get the part. Meanwhile, I am without a vehicle. I only have approx 25,000 on the car. We have not been given a replacement car or been given any clear response from GM or the Dealership as to how long this may take to locate a part.

Main Issue: Ongoing issue with stuck caliper causing the pads and wheels to overheat increasing the tire pressure to dangerous levels. The regenerative braking system is actually very effective in slowing the car when driven in L mode. If driven smartly, driver rarely have to use a lot of force using the physical brakes and rotors. Three times now, I have had issues where the front calipers were seized and the brakes were stuck causing the wheels to have visible smoke, odors and extreme temps. Perhaps they are not being used as much as normal brakes but service was done at the dealership on both cases, only to have the issue return within a year on a low mileage car. Looking at online forums, this appears to be a common issue with the Volt. Often the High Pressure Accumulator (HPA) is not properly reset during a brake job. [XXX] I have had other non EV cars with regular brakes that worked fine for > 50k miles before service, so there is clearly an issue here. Ironically, as these brakes caliper/pistons/rotors are less used due to regen, the chance of them getting stuck seems to be an issue when they are actually engaged leading to dangerous conditions.

Chevy Volts from 2016 - 2019 all have a manufacturing defect which can prevent the driver from powering - the error message is "Shift to Park". GM released a Volt Service Bulletin in May 2021 but offered no assistance to replace the defective part. On [XXX] I was driving home on [XXX] headed [XXX] from Santa Cruz in fair weather in the afternoon. This highway can be dangerous with limited shoulders and poor visibility, making it an unsafe place to pull over. While traveling at about 55 mph, the car made an alert sound and illuminated the check engine light and presented a message "Shift to Park". I was running out of room on the shoulder to pull off safely so I had to make the quick decision to pull off to the left-hand shoulder. I followed the instructions on the display which said to shift into park, followed by shifting back into drive. During this time I had my foot on the brake, but after removing my foot from the break, the vehicle began to roll towards traffic, so I put my foot back on the break. I tried powering the car off/on multiple times and tried to get the car to go back into drive but was unsuccessful. Eventually, I put the car back into park, called a tow truck driver, and waited for over an hour to have my car safely towed off [XXX]. Prior to this, I had not experienced any of these or similar symptoms. An OBD code scan was done (screenshot attached). Once at the Chevy dealership, they confirmed that the car could, at that time, shift into park and were not a

Abs system failure due to defect The cause of the condition may be a fracturing of the front half shaft anti-click washer (1) and possible collateral damage to the ABS wheel speed sensor (WSS). this defective $5 part causes thousands of dollars of repair this should be a recall as there are numerous reports of these parts failing and causing the vehicles braking system to be impaired this failure has happened to this vehicle 2 times with in the last 60 days

Early on the week of November 9th my car displayed a message that there was "Low propulsion power - engine not available." Upon returning home and parking the car it started without incident the following day. On November [XXX], my vehicle stated "Low propulsion power - engine not available" but this time the car shut down completely leaving me unable to return home. I had the car towed to Fairway Chevrolet for repairs. The service technician indicated that the catalytic converter needed to be replaced and the part was out of stock and would take 3 weeks to become available. No rental or loaner car was provided. On November [XXX] I was told that my car was fixed and it would be able to be picked up. I picked up the car and parked it at home and drove the car I was currently renting to California for the Thanksgiving holiday. Upon returning home, I returned my rental and returned to my car. The car behaved normally but after driving down a busy roadway for less than 2 miles the "Low propulsion power - engine not available" message reappeared and the car shut off IMMEDIATELY. This is horrifyingly dangerous especially considering the speed and location of where I was driving. I had the car towed to Fairway Chevrolet but didn't speak to anyone until the morning. In the morning I called in and explained what happened and stressed the safety fact that my car was returned and malfunctioned in a very dangerous way. The tech said that they were going to perform a diagnostic which they

Lost propulsion power went from doing 75mph to 35mph on the fast lane with no warning vehicles swerving to avoid hitting me..very scary and dangerous 3rd time this happens I now try to avoid fast traffic.. please look into this someone going to get hurt if no action taken..

My 2018 Chevy Volt has experienced the GM knows BECM issue. There are several Volt Owners that have experienced this issue. I would like to bring this to the attention for GM to post a recall/mandatory service repair as my car stopped working, would not start, was displaying false information on the electrical module, etc. Issue: 1. Car would not start 2. Battery stated fully charged with solid green light but display showed only 1 electric mile available 3. Tried to shift car to Reverse press gas nothing happened 4. Tried to shift car to Drive press gas nothing happened. 5. Car engine light is on 6. Utter confusion as stress as I’m stranded with no way to get my car working 7. Chevy dealership has had my car for one week now with the only update of ordered BECM module. No ETA on when this will be fixed 8. No indication of what caused the issue

My 2018 Volt had a reduced propulsion power message and stopped running on its ICE in early Oct 2023 and because the battery was dead the vehicle wouldn't run at all. The next day 10-3-23 I was able to charge the battery and then brought the vehicle to the dealer for diagnosis. The problem seems to be with the EGR valve and the dealer ordered one at that time. It's been 3 1/2 months and there is no sign of the part. The car is only usable for its 55 mile all electric range which is often not enough but our family by borrowing cars and getting taxi rides and taking buses. This is by most measures unacceptable.

After recent repair of hybrid transmission, experienced a loss of power, MIL, and several trouble codes related to the battery control module (BECM). This affects safety as the loss of propulsion unexpectedly causes deviations in speed from typical traffic flow. The problem was confirmed by OnStar and a manufacturer representative was advised with a dealer appointment scheduled when they next open. There were no lamps or other symptoms prior to this MIL and loss of power. Restarts after shut down have not been attempted until able to take the vehicle to the dealership.

My 2018 Chevy Volt was at a Chevrolet dealership in Burbank and they have been running tests on my car to re-create the problem which they have not been able to do. On [XXX] my car suddenly stopped and shakes violently after I turned it on after about driving 15 feet, and my screen was telling me “engine not available, service needed soon” so I got it towed to the dealership (no prior warning signs on dash or anything). On [XXX] they told me they were not able to find the fix or recreate it and also said “This is definitely very rare. Drive it around and bring it back in if it happens again” which felt like they really didn’t care for my safety at all. On [XXX], the same exact problem happened with my car, “engine not available, service needed soon” and shook violently (my girlfriend witnessed it) after 100 yards of driving it and then towed my car back to the dealership. On [XXX], 23 DAYS LATER, the Chevy dealership calls to tell me they still haven’t been able to recreate the problem or find a solution again. I haven’t been able to drive my car this whole time. I have had a case open with GM this whole time where they have been extremely spotty on communication and pretty much just ignoring me the alot of the time. They called me on Saturday, [XXX] (when they’re “closed”) to tell me their solution but I missed the call, I called Monday and Tuesday but can’t get in contact with my advisor until finally Wednesday, I call and they are able to connect me and they gave me a fina

My BECM failed pulling in to my grandpas house. I was able to park the car, but unable to start it afterwords. Prior to failure, the engine would switch between electric, then back to gas, then back to electric This is a very common issue on these vehicles. I am fortunate this did not occur on the highway, as I had just exited I 94

"Propulsion power reduced" message along with check engine light, loss of propulsion power from battery, loss of ability to charge battery. OBD2 scanner reveals P1E00, and 12 U26xx fault codes relating to Battery Energy Control Module failure.

The BECM on my 2018 Chevrolet Volt has failed and I am being told it may be months before the dealership will have the part to fix the issue.

After getting some repeated "propulsion power is reduced" display warnings, my 2018 Chevrolet Volt literally died without warning while I was driving it on New Year's Eve and could not be restarted.

Chevy Volt lost power while driving on the highway. No warning. The car has been at the dealership for 3.5 months and they have yet to tell me what the issue is, I have asked every time. Seems as though they don't want me to know. HIghly likely it is is BECM issue. Also, I scheduled the car to be looked at via their app, the day I arrived for the appointment no technician was available, and said I needed to reschedule and bring it back in a week. I just left the car there because it was incredibly unsafe.
