2017 CHEVROLET VOLT Complaints

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?

My car started having issues with the hybrid system, with fault alerts related to the drive motor control module, hybrid powertrain control module, and battery energy control module in the transmission, and the vehicle is available for inspection if needed. The engine light had been on for about a week, and I was waiting for availability at work to take it to a mechanic. While driving around 70 mph on the highway, a “Propulsion Power Reduced” message suddenly came on and the car started limiting its speed. As I kept driving, the power continued to drop, making it unsafe to stay at highway speeds and putting both me and other drivers at risk since the car couldn’t keep up with traffic and could slow down unexpectedly. I took it to an independent mechanic who confirmed the issue and warned me it was dangerous to drive because the speed would keep decreasing as power dropped. So far, only an independent mechanic has inspected it. After doing some research, I found this is a very common problem with 2016–2018 Chevy Volts, with many people reporting similar situations where their cars lost power or started jerking at high speeds and they had to pull over.

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

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, and January 11th, 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.

Experiencing intermittent propulsion system failure with multiple simultaneous warning messages on 2017 Chevrolet Volt at approximately 59,000 miles. WARNINGS DISPLAYED: - "Propulsion Power Reduced" message - "Check Tire Pressure Monitoring System" (false alert - all tires properly inflated and recently replaced) - Multiple dashboard warning lights including exclamation point indicators - Vehicle exhibits abnormal driving characteristics PATTERN: Issue occurs intermittently while driving. Vehicle can be restarted and may operate normally afterward, then fault returns unpredictably. SAFETY CONCERN: This matches documented Battery Energy Control Module (BECM) failure pattern referenced in GM investigation N232432680/PE23022 and Customer Satisfaction Program 17228 recall N172096420 for reduced propulsion power in 2016-2018 Volts. Review of owner complaints shows other 2017 Volt owners experiencing sudden complete loss of propulsion while driving at highway speeds, creating dangerous situations requiring evasive action by other drivers. RISK: Loss of propulsion power while driving with dependent passengers creates serious crash risk. Vehicle is used for daily transportation of minor children. REQUEST: Vehicle exhibits known defect pattern but manufacturer has not extended recall coverage. Request investigation into whether recall should be expanded to cover additional affected vehicles.

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.

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.

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.

My 2017 Chevy Volt is having Battery Energy Control Module (BECM) issues. I receive the occasional error message of "propulsion is reduced" and engine fault codes of P1E00, U2619, U2620, U2621, U2622, U2623, and U2624. GM issued a Special Coverage bulletin (N232432680) extending the warranty for the Battery Energy Control Module (BECM) on 2016-2018 Chevy Volts to 15 years/150,000 miles. My Chevy Volt is within this year and mileage range, but for some reason my Chevy Volt VIN is not included in this Special Coverage (N232432680), which means that this special coverage for some reason doesn't apply to my 2017 Chevy Volt, even though it has the same issue. Is there a way that my 2017 Chevy Volt VIN can be added to this Special Coverage bulletin (N232432680) so that I can get warranty repairs? Thank you.

I was driving in stop and go traffic on a relatively busy road when I was cut off. I braked hard to avoid a collision. Immediately afterwards, the car would not respond to the accelerator and would not go forward. I was in the middle of the road and the car would not respond. It could have caused an accident. I put the car into park and then back into drive and it seemed to work again. But I am now worried about the car.
