general problems of the 2018 Chevrolet Volt

It was the xxx recall for the dtc p0442/check engine light code. The dealership said that the recall had been satisfied in 6/2020 by putting a buffer in to separate the 2 lines but not replacing the part. Now the exact same code dtc p0442/check engine light in the exact spot that occurred for the original recall. The dealership originally quoted $5,093, then after me complaining that it is the same recalled problem they dropped the cots to $2384. I believe that is an agreement that the manufacturer should cover this. Of course I will have to pay to get my car but I would like the manufacturer to reimburse me for it seeing it was a manufacturer default. I spoke to the manufacturer they flat out refused to cover it. I obviously disagree. Would like you to pressure them to change their decision.

The contact owns a 2018 Chevrolet Volt. The contact stated that the battery module became inoperable. While attempting to start the vehicle, the message "engine unavailable - service soon” was displayed. The contact was unable to use the vehicle. The contact stated that the tpms warning light was illuminated. The contact associated the failure with technical service bulletin: 18-na-261. The contact called the local dealer and was referred to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 111,000.

My wife and I were on a 200 mile trip and the engine failed about 150 miles into the trip. Was driving and the instrument panel indicated that the engine was in reduced power mode. I switched over to battery power but had only approximately 10 miles of range left so after a couple of miles I switched back to engine power and was almost immediately informed by the instrument panel that the engine was in failure mode. Was fortunate that there was an exit nearby and was able to use the remaining battery power to exit the highway and pack the car before there was no power. The car was towed to a dealer and we were told that the egr valve and cooler had failed. They were replaced and I was told that they were not covered by the federal emissions warranty so the cost would be $4000. The car was driven with the vast majority being electric power.

On may 26, the car was running in electric mode and switched to gas because the power batteries were depleted. Shortly after switching to gas mode, lights came on the dash board saying engine not available get service immediately. I was on a highway at the time and fortunately had just enough left to get off and the car would not move any further. Turning the car on and off did not resolve the problem. It had to be towed to a chevy dealer. Even after an hour, the messages would come on when trying to start the car. The next day, the dealer called and said they could find no problems with the car and it works fine. This happened once before, but that time there was enough charge in the battery to get home and then later it would start without the message.

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.

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.

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.

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.

In June of 2023 the car experienced propulsion power reduction. The car was at the dealer awaiting repair for 3 weeks. On Dec. 14,2023 the same thing happened again. The car was also unable to accelerate once mobile. The car has about 90k miles on it.

The vehicle will lose power without warning on a regular basis. The vehicle will also accelerate unexpectedly when switching from battery to engine power at speeds under 50 mph. I have taken the vehicle to the dealer and have been informed there is nothing they can do for me, the vehicle does not have any faulty components.

The battery energy control module needs to be replaced (becm). The car is available to be inspected at key Chevrolet in south burlington, vt. The car was parked when it failed. The car wouldn't start (lights on the dashboard came on) and it wouldn't turn off. I got a "shift to park" error message, regardless of which gear I was in. The car wouldn't go into drive to go forward with either the drive battery or the gas generator. I had the car was towed to the dealership. It was inspected and diagnosed by them. When they did the diagnosis, they said the becm had failed and there were cells in the drive battery that needed to be replaced. The becm failure is a common problem with Chevrolet Volts and is covered by the Voltec warranty. There were no warning lights or other warnings (e. G. , reduced propulsion) whatsoever. The car had shut off like normal but would not start or turn completely off. I was fortunate to have had the becm fail while the car was parked. My understanding is that becms can fail while the car is moving and the power will stop and you won't have any control.

Car died while driving down road. Has engine codes to service high Voltage system although it showed a full battery it only had 1 mile range and the gas motor wouldn't run.

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 November 8th 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 November 15th 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 December 4th, 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 December 27th, 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, Dec. 30th @ 8:29 am (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 final solution on Jan. 3rd of $1500 off a new gm brand car so they weren’t in any rush to contact me about the final solution. They should repurchase the car from me and pay for damages. Car feels extremely unsafe and there should at least be some type of diagnosis… Chevrolet cant fix their own cars, unreal!!!!.

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 9th, 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 22nd 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 were going to charge me for, even though the original repair did not fix the defect. Fairway performed the diagnostic and stated they need to clean the engine bay and run a separate diagnostic of the brake system. These total more than $1. 6k out of pocket and are not related to the power deactivating while in motion. My car is still at fairway as they have not started the repairs and I am still self paying for a rental car. Fairway is uncooperative and refuse to check into the propulsion.

While driving my 2018 chevy Volt I received a reduced propulsion error. I pulled over to assess and turn off the car and turn it back on only to find when I turned it back on I received an enginer failure error and the car would not drive forward or reverse. I had to have it towed to a chevy dealership for evaluation. I understand from research and talking to service experts this is a common failure among the 2017 and 2018 chevy Volt and it is abhorrent that chevy has not issued a recall on a common failure that compromises the safety of the driver and other drivers around them.

To begin, I will set the scene of my experience. I was traveling east bound on 84 in northeast PA on my way to long island for work meetings that day. I was about one hour and a half away from my home at roughly 6am. I was traveling at apx. 70 mph when my car suddenly says "engine unavailable, reduced propulsion. " and the fueld tank turned yellow in color on my dashboard. Then a sign said "service soon. " my car then completely stopped working. My speed fell from 75 mph or so to 0 in a matter of a minute, I had no idea what was happening because there were no appropriate warnings such as, "pull over immediately" or "safety concern please get off the highway" -I would have taken anything to know that this was an actual emergency and I needed to at least get to a shoulder. I luckily was able to come to a stop mostly off the highway in a shoulder. I was located around a bend, in the pitch black, unable to stay in my car out of fear I would be smashed by a tractor trailer or car that did not see my car suddenly stopped. The car would not go in neutral or anything other than park and I left the hazards on (they eventually failed). I called my husband who drove to me while I stood on the side of the highway for an hour and a half in 30 degree weather. I called the police who were eventually able to put up flares and mark me as a hazard on the road. If there was a car traveling behind me, I would have been killed or seriously injured because I slowed so suddenly and had no way of knowing that this was an absolute emergency. The worst part is that this is the second becm failure in my Volt and I have driven less than 1000miles since it was repaired the first time (which took >5 months). The first time this happened my car was on a quiet town road and my brother who was driving just parked and had it towed. He hadn't thought there were any warnings but he wasn't sure. This time, I could have been smashed on the hwy with little to no warning. I can't believe im alive.

Reduc d propulsion power warning while driving in ev mode. Ice started and was able to make it 1/2 mile home. Failure diagnosed to a faulty becm. Has been at the dealer for 1 month today with no word on when the part or repair will be done.

Becm failed upon startup. Pressed start and vehicle appeared to turn on. Shifted into reverse but there was no motor power and I began to roll backwards down the driveway. Started the vehicle again and then the engine came on and a reduced propulsion message appeared.

When the gear shift is placed into park and the power button to turn the car off is pushed, I get an alert that says “shift to park” and cannot turn the car off. I have to attempt to turn the car off and on several times before I can actually turn the car off and leave it.

When attempting to turn the vehicle off after parking, the driver's console displayed the message "action required: shift to parlk". The shifter was already firmly in the "park" position. Moving the shifter back to "d" and then back to "p" did not resolve the issue. Pressing the power button twice more resolved the issue this time without further moving the shifter. This is a well-known and well-documented issue with "gen 2" chevy Volts.

When I stop and shift vehicle into park and try to turn off vehicle. The vehicle does not recognize the vehicle is in park and will stay running. This had happened numerous times and is ongoing. Have read there is even a class action suit because of this problem with numerous different gm vehicles. Why has a recall not been issued?.

The dealer reported having repaired an emissions recall for a fuel vapor leak, however the repair was ineffective and the vehicle still reports the leak as a fault code "slow" and "fast" emissions leak. The dealer refused to recheck their work without payment. Recently I came into possesion of a borescope camera and was able to photograph the dealer's "repair". The photos clearly show the parts for the emissions repair are located in the wrong place as compared with gm's own service bulletin. Therefore the dealer did not do the repair, or failed to do the repair, and refused to check there own work without compensation when informed of the continuing problems and left me to do their recheck of their work at my own expense. I have provided photos of the gm prescribed parts placement and the incorrectly placed parts in my car as well as the resulting damage. We never experienced the relief intended to be provided by the repair service. They claim to have performed the necessary recall service, but that is a false claim. See Chevrolet TSB n192273600. Not performed correctly so failed. The dealer, haselwood Chevrolet, bremerton washington, was contacted by phone and email but offers no response. They have the pictures of the botched repair job. Additionally the car needs warranty service for a bad park switch which service they refuse to perform without my agreeing in advance to pay for that in warranty repair.

Shift to park defect. When I try to turn my car off it won’t completely shut off, a notification on my dash says “shift to park” but my gear shift is in park already. It takes 5-10 times of me cutting car off and on for it to finally completely shut off.

Car will not shift to park. Will not allow the car to be turned off.

General: when I would shift to park, the display would indicate I was in park, but the car would not turn off. I sometimes had to spend 10 minutes trying. The safety issue was if the car is left on it because the engine system would not recognize park, it could run from gas and create deadly fumes. 1. Shift stick and harness. I do not have the part. 2. Confirmed by dealer and part replaced. $491. 33 3. Unsure if it was inspected. Google search has multiple listings for this issue 4. No warnings, no lamps prior to. Warning message when shifted to park and trying to turn off.

Vehicle will not turn off on a regular basis. . Receive a message that reads: �action required. Shift to park. � when this occurs, the vehicle can not be turned off or locked. Researched this problem on the internet and discovered that it is a very common problem that affects nearly all 2016, 2017 and 2018 Chevrolet Volts. A recall should be implemented!.

Car is consistently making a burning smell and the dealer is refusing to acknowledge it. I went there 2000 miles ago, they claimed it was a break in smell. The smell is still there and once again they are calling it a break in smell. I mean the car has 8400 miles. How long does it have to break in for? NHTSA, please step in and help us. Gm is creating this possible fire hazard and their franchises are not helping.

When my gas engine is warmed up and up to operating temperature, there would be this burnt plastic smell coming from under the hood. It's been happening like this for the past 3000 miles or so. It's a clear burnt plastic smell from under the hood, and it is always after the engine is completely warmed up. I use my gas engine all the time. The dealership claims it is normal for hybrid to burn stuff off as it isn't run all the time, but the car has 6700 miles. It's a stretch to blame it on break in oil. Some of the smell gets into the cabin when I am stopped, but it is very strong when I get out the car and walk by. It's been happening for a few months now.

While driving the vehicle at around 60 mph, the �check engine� light came on and a message saying �shift to park� appears on the dashboard. Once the vehicle was stopped at the traffic light, the driver shifted to park and was not able to pull down to drive again. Vehicle was stranded in the middle of the road while cars were approaching from behind with high speed. After repeated attempts to press the vehicle �start� button, we finally were able to pull down to neutral and pushed the vehicle to the side of the road. Vehicle needed to be towed to dealership for diagnosis.
