Three incidents in the last few weeks. My 2017 Chevy Volt today has about 84,000 miles. First incident, While driving on an interstate at about 50 mph I suddenly lose ability to accelerate. There was some beeping, dashboard turns yellow, I get a low fuel warning and I cannot accelerate. I pull over on interstate. Re-start vehicle and car restarts. Second incident, driving about 20 mph leaving a neighborhood. I have 4 passengers, all kids. The same exact error happens. I’m unable to accelerate though I’m pushing down on gas, fuel light turns yellow. Low fuel light. I pull over. I restart vehicle. Car starts normally. Car goes into shop. Chevy dealership says it’s the catalytic converter. About a week later, 3rd incident. Entering highway at about 60 mph, trying to accelerate and merge into traffic doing 70 mph. I cannot accelerate past 60 mph, I hear the beeps, fuel gauge turns yellow, low fuel warning. Check engine light turns on. Several days prior to this, I had a low propulsion error on dashboard momentarily. But it went away when I restarted vehicle. Safety of myself, passengers and other drivers were out at risk as there was no warning that I would lose ability to accelerate. There was a no fuel warning but my gas tank was mostly full.

The EGR valve had an electrical short, causing the 15A F03 fuse to blow. This causes a "reduced propulsion" message to appear and also causes the vehicle to start overheating.

The EGR valve had an electrical short, causing the 15A F03 fuse to blow. This causes a "reduced propulsion" message to appear and also causes the vehicle to start overheating. The faulty EGR valve is available for inspection. This failure occurred while we were on the interstate driving 70mph. We were also at least an hour from home/family. The EGR valve short is a known problem with Gen 2 Chevy Volts. Online message boards are filled with posts about this issue. The vehicle was inspected by a Chevy dealership (we had to have it towed). However, the EGR valve is on national backorder with no ETA on when they would be available again. We are currently driving the car with the valve unplugged. However, this causes the engine to run less efficiently and at higher temperatures, so we cannot run it for long periods of time. There were no warnings before the problem occurred, it just suddenly happened while we were driving on the interstate. Luckily we were near an off ramp and a hotel; since the problem occurred on Easter weekend, there weren't any dealerships open.

While driving down the highway a "reduced propulsion" message appeared on the dashboard and the drive became very rough if speed changed, also the engine temperature increased but it did not overheat before we could stop. This was diagnosed as an Exhaust Gas Recirculation (EGR) Valve failure. I spoke to multiple dealers and did research online as well and this is a very common issue on this vehicle. So common that the part is impossible to get and has an eight month wait which means I cannot drive my vehicle. What component or system failed or malfunctioned, and is it available for inspection upon request? EGR Valve How was your safety or the safety of others put at risk? My car had reduced propulsion, engine temperature increased and it suddenly lost speed quickly on highway when my foot was removed from gas pedal. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, Chevrolet is aware of this issue and say we just have to wait 8 months for the part. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No pre-warning a "reduced propulsion" message and a check engine light turned on at the time of the EGR valve failure.

Driving at freeway speeds when suddenly the cars propulsion power failed and I went from 75mph to 45mph with no warning and no way to accelerate. Happened multiple times even after pulling over and turning the car on and off. I was told by the dealership that was a gas engine part and that I could drive it on the electrical engine only. When attempting to drive on the electrical engine, I received a notice of engine failure and had to coast into the driveway of a dealership. I was told the engine “could explode” if I continue to drive it

This would be my second time replacing the EGR valve if the parts were available but they are not and there is no anticipated delivery date. The parts are covered in CARB states (those that have adopted California's emission rules) but not my state of NC.

2PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025

On November 29, 2023, the Office of Defects Investigations (ODI) opened PE23022 to investigate allegations of a loss of motive power, including a stall, reduced power state, and/or a no start condition due to the Battery Energy Control Module (BECM) in model year (MY) 2016-2019 Chevrolet Volt passenger car vehicles manufactured by General Motors (GM). The BECM is located within the high voltage electric vehicle (EV) battery pack and monitors the temperature, current, and voltage of the high voltage battery cell groups. GM stated that the root cause was identified as an internal failure leading to a loss of communication within the BECM and does not pose a risk to motor vehicle safety. GM further stated that the failure cannot result in a complete stall, only a reduced power mode, no start condition, or a no charge condition. GM additionally stated that if these conditions occur, the driver will be warned via a Malfunction Indicator Lamp (MIL) and/or a reduced-propulsion message in the Driver Information Center (DIC). Data received and analyzed by ODI from all sources indicates that nearly all related BECM failures caused conditions aligning with GM’s predicted outcomes. Despite the large number of warranty claims, nearly all failures were not safety-related, i.e., not a stall or reduced power mode. ODI isaware of a single minor crash and no injuries or deaths. In March 2024, GM issued Special Coverage N232432680, which was mailed to consumers, addressing BECM failures in certain MY 2016-2018 Chevrolet Volt vehicles. This special coverage provides an extension of the warranty coverage for the BECM from 8 years / 100,000 miles to 15 years / 150,000 miles for all 2016-2018 Chevrolet Volts. Additionally, GM stated that replacement components are sourced from a different supplier and not susceptible to the failure. In view of the Special Coverage issued by GM, the existing warranty coverage already in place, and the low number of safety-related occurrences, ODI is closing this Preliminary Evaluation (PE). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
