Traveling from Mexico, we just got into yuma Arizona heading towards the 8 freeway when my volt displayed reduced propulsion and the engine light came on and the car lost power while driving on the road we had to let the car drift into a parking lot. We let the cat sit for a several minutes and the engine started up but was running hard. After that it ran a little so we decided to rent a uhaul and car hauler to get the car home. Before this happened We were about to head back to California and we were stranded there until we got an Uber to the uhaul place and rented a truck and car hauler, the car would stay on long enough for us to drive it up on the ramp so we had to push the car to get it up there. We finally did and 24 hours later we made it home hauling the cars a 3 hour ride home was turned into a nightmare. Apparently this is serious problem if the car would have stopped a while we were driving through Joshua Tree we would have been stranded on the side of the narrow road in the dark, Or on a major free way, This problem is a safety hazard to all Volt owners and it has been known and reported to happen countless of times so why is there no recall of these vehicles for this problem, people's lives are in danger, this could have turned out way worst, thank God He saved us from what could have happened. My dealer says that they are not sure what caused it and that we may have to pay for repairs. This is unacceptable because there is an obvious problem with this vehicle

At approximately 61,500 miles my Chevy Volt would not start. I had it towed to a repair facility who determined the problem was a faulty BECM (Battery Energy Control Module), but that it would still be covered by the manufacturer's warranty. So I had the vehicle towed to a dealership. The vehicle has been at the dealership for six weeks as of the time I write this, but report they have yet to diagnose the problem or offer a solution. Doing research online I have found that BECM failure is a common problem among the Chevy Volt, of all model years. And due to "supply chain disruptions" people are having to wait weeks to months for their vehicle to be repaired. Fortunately my vehicle did not fail in a dangerous location, however the BECM failure could happen randomly at any time at any mileage and appears to be a design flaw. Fortunately my vehicle is still covered by the manufacturer's warranty, but in my opinion, repair should be extended to all Chevy Volts.

BECM failure caused vehicle to lose propulsion. Could have stopped working in a dangerous situation such as an intersection, steep hill, or railroad tracks.

This is related to a long-standing issue with the failure of the Battery Energy Control Module (BECM) (part #242969-00) for the 2017 Chevrolet Volt, as well as a lack of availability of the replacement part. This is a documented problem in the NTSA database since 2016. The vehicle error messages on the dashboard include -??unable to charge-??, -??shift to park to start-??, -??reduced propulsion acceleration may be limited-??. The internal combustion engine engages even with a full battery charge on an intermittent basis. Only after turning the car off and on several times or later the next day, would the problems resolve. In several instances, there was a lack of power transfer to the wheels when in drive mode and traveling on roadways, and the car had to be turned off and on to resolve this problem. The car has been inspected by a Chevrolet dealer to confirm the BECM is failing and needs to be replaced. The replacement BECM was ordered by the dealer 7 June, 2022, and neither GM or the dealer will provide a delivery date for the part. A number of postings on www.gm-volt.com reported 2017 Volts would no longer turn on or would lose power when being driven, could not be driven, and had to be towed. The NTSA database indicates approximately 250 complaints have been filed for 2017 Volts that include vehicle error messages on the dashboard for -??unable to charge-??, -??shift to park to start-??, -??reduced propulsion acceleration may be limited-?? and loss of power while driving. Although no accidents or deaths were reported, this is clearly a serious safety issue that NTSA should address immediately with a mandatory safety recall.

When attempting to engage the vehicles drive system, it would occasionally fail to recognize the propulsion system battery. This could potentially leave someone stranded in dangerously high or low temperature environments without food or water. Powering off the vehicle and then powering the vehicle back on would sometimes fix the issue. The issue occurred very randomly and was unable to be reproduced once working again. It would continue to happen more frequently and require more tinkering to get it working until almost complete failure. This appears to be a common issue and found to be the result of a failed BECM (battery energy control module). It triggers the check engine light and a series of trouble codes. It is estimated that the replacement of this module takes roughly five hours. Unfortunately, supply chain issues have recently resulted in owners being without their vehicle for multiple months with no loaner vehicles available and no additional compensation.

Our VOLT yesterday had a complete Battery Electronic Control Module Failure. This is apparently a VERY common problem with 2017 models. The car is not drivable once this happens are parts are back ordered. I read 1 dealer had 4 just sitting there waiting for the part. Some people over the past year have been waiting up to 100 days for the part. Yesterday at Keys Chevrolet in Van Nuys, CA we were told it would take at least 1 month to get the part is. If the problem is this prolific GM needs to produce more parts or issue a recall for these cars. All these customers should not be without their car for months at a time because parts are not available.

My car had the Shift to Park and Battery Control Module go out while on a family trip with the family in the car, on the highway. The car was in the left lane of 2 lanes on the highway with no propulsion or way to move it except to push push the car off the side of the highway. Thankfully some people stopped to help. My car had stopped with no way of moving on a 55 mph 2 lane highway. We were at risk of cars not seeing my hazards and hitting us from behind. We had to push the car across the right lane to get it off the road. We had two cars stop to help direct traffic away from us while we pushed it to safety. But when we were on the side of the road, we were stranded in 100 degree heat along side a busy highway and the car was not able to use the HVAC because of the issue. This is a known issue and has been for years. A google search of VOLT Shift to Park Battery Control Module will result in THOUSANDS of complaints. It has become general knowledge that if you own this model, you WILL have this issue. They ALL will, it's just a matter of WHEN. It can happen at 30,000 miles or in my case, 111,000 miles. Chevrolet knows this as well as the dealerships. I have read many other stories of people being left stranded because of this. Chevy covers it under warranty. But my car was 11,000 mile past warranty. So I had to pay full price. Every dealership I called to see if they had the part to fix my car said that they didn't have the part AND they had 1 or more of my type of car in their dealership currently with this issue at any given time FOR YEARS. Thankfully since my car wasn't in a wreck, there was no police or insurance paperwork filed. Once the shift to park issue happened while I was driving and we were stranded, the check engine light came on. It was not on when I started the trip up until the car died. Then the check engine light came on.

On 2 difference occasions over the past 3 weeks, my car has malfunctioned while I was driving. There were no warning lamps, messages or other symptoms prior to this. All of the lights on the dash came on, the power steering went out, the brakes would not work properly and I could not accelerate. I had my child in the car and we narrowly avoided being hit by other cars both times since I couldn't control the vehicle. I couldn't even power the car down initially but was finally able to turn it off and back on and function resumed after several cycles. I was driving on electric battery that time. The first time, the dealership stated that the following codes were present: P1e00 and P16BA. They replaced the g1 a/c compressor. The incident occurred again a week later when I was driving on gas. At that time, there were history U codes present for every module, per the technician but no current codes to identify the problem. The problem has not been able to be reproduced since. The 2nd incident occurred out of state and my car was towed back to Texas where I live. The dealership there refused to investigate the incidents since they couldn't reproduce them and there were no current codes showing. It has subsequently been towed to a different dealership where they are still trying to identify the issue. I contacted General Motors and was contacted by a rep who escalated the issue. The next rep escalated it again greater than 48 hours ago and I have received no further contact from GM. The 2nd rep informed me that since the dealership that it was originally at says that it's safe to drive that they can't do anything. This car is NOT safe to drive.

BECM shut car down and has gone into low propulsion mode causing danger in traffic.

- North Canton, OH, USA

I was driving 65 miles per hour on the freeway and suddenly my car lost propulsion. A light came on that said the car had lost propulsion and I had no power to keep driving on the freeway. Luckily, I was able to get to the side of the road without getting hit by other cars, but it was a close call and very scary. I had it towed to the dealership and they could not find any problem with it after investigating for an entire week. They gave it back without any repairs because it was apparently working fine for the dealership. This same problem happened again about 6 months later as I was driving up a long hill. Again, it was a scary close call to get to the side of the road safely. This time I just turned the car off and let it sit for awhile. Then I turned it back on and everything seemed to be running just fine. This is a major safety problem. I-??m now afraid to drive this car and no one seems to know how to fix the problem!

Shift to Park alert. Vehicle does not think it's in park when it is actually in park.

- Orting, WA, USA

Went into a store to pick up a snack and the cashier noticed that my driver side door was on fire. The entire indoor panel was melted and burned. It looked like the fire started on the inside of the door panel where the wiring is. The car was turned off at the time of fire

- Springfield, VT, USA

Car couldn't be turned off. Dash would say "shift to park" when it was already in park. The problem was intermittent but the number of times needed to get the car to shut off was increasing. GM was aware of the problem but said it hadn't risen to Recall status. I saw over 500 of the same complaint online. They charged $800 to replace the switch and wiring. GM has stopped making Volts, so that could be why no recall"?"

I am having a shift to park error message when I am in park

- Encino, CA, USA

The car suddenly started starting problem, then the electrical charging component to refuel the power from an electrical charging outlet was unable to charge. Now it does not start at all. I brought the 2017 Chevy Volt to a dealer, it has been more than a week and they said that the part to fix the problem is not available yet and I have to wait. They do not have any idea when they will get the part.

BECM (Battery Control Module part # (24296900)) on my 2017 Chevrolet Volt failed. When the failure occurred the instrument display showed a -??Propulsion Reduced-?? warning. At the same time the engine started (the traction battery was fully charged at the time) and the check engine light came on. I subsequently received an email from General Motors that they had detected a lithium ion battery problem with the car and to have it serviced within 7 days. The GM dealer subsequently diagnosed the issue as a failure of the BECM module. Although an online search of this issue shows that there have been hundreds of failures of this module there are no replacement parts currently available. The car has been sitting at the dealer for several weeks with no estimate of when a replacement part will be available. The dealer has recommended not driving the car until it is repaired. I was able to drive it to the dealer on electrical power after the failure occurred.

I received a 'Reduced Propulsion' message along with a check engine light and that progressed to a 'Engine not Detected" message and stranded along the interstate in a dangerous situation. Had it towed to a dealership which had a technician which could work on a volt - he replaced the Engine Control Module fuse which "fixed" the car for about 15 miles and then the 'Reduced Propulsion' error with the Check Engine light appeared. Technician said something must be shorting out the fuse. Dangerous situation.
