The EGR valve in my Volt suddenly failed with NO warning while driving 70 mph on the highway. I had to pull over before the engine overheated and I stopped on the side of interstate in a very tight shoulder on a curve with traffic and semi trucks passing by very closely. I’ve now been waiting over one year for repair as Chevrolet is unable to make this part for a repair that is still covered under warranty. Very disappointed and I hope this report will help push a larger message through that Chevrolet is being irresponsible with making parts for the needed warranty repairs.

SERVICE BRAKE BOOSTER EMITS A SEMI CONTINUOUS TAPPING/CLICKING NOISE. CHEVROLET STATE THAT IT IS NOT A SAFETY ISSUE AND DOES NOT REQUIRE REPAIR. HOWEVER, IT IS DIFFICULT TO HAVE CONFIDENCE IN THE BRAKING SYSTEM WHILE THIS SOUND PERSISTS AND IT IS A CONSTANT DISTRACTION WHILE DRIVING. PLUS, THE ABILITY TO SELL OR TRADE THE VEHICLE IN THIS CONDITION IS DIMINISHED. ELIMINATION OF THE NOISE INVOLVES COSTLY REMOVAL AND REPLACEMENT OF THE BRAKE BOOSTER ASSY. CHEVROLET FIXED AN APPARENTLY IDENTICAL ISSUE ON THE BOLT MODEL WITH A SOFTWARE UPDATE, BUT CURRENTLY HAVE NO INTENTION TO DO ANYTHING SIMILAR FOR THE VOLT MODEL.

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 car stalled at a high rate of speed on a freeway because of EGR failure. Engine check light is on, along with a warning about a critical problem with emissions system that requires immediate attention. The part is out of stock in all dealership within a reasonable reach. The problem is under warranty, but I have made multiple attempts to fix this issue with no success.

EGR valve failed. This can cause the Volt to stall in traffic. No ETA on replacement. The situation seriously limits driving ability. Reduced propulsion and engine light came up. f3 fuse blew related to failed EGR. This is a known issue with Chevy Volts. It was checked out by dealership in Aug. They replaced fuse and basically said can only drive on electric. If turns over to gas it could cause major problems.

The EGR valve had failed, causing a check engine light, which turned into a blown fuse. The fuse blowing left the vehicle stranded until I unplugged the EGR valve and replaced the fuse. I drove it to a shop, where they replaced the valve and the car has been functional since then.

The EGR Valve on the vehicle went bad, causing the vehicle to display 'propulsion reduce' and 'engine not available' errors on the dashboard before the vehicle came to a stop while driving on an interstate. Searching this issue for the Chevrolet Volt online yields a significant amount of similar issues experienced by other Volt owners. Vehicle was inspected and repaired by a Chevrolet dealership, but seems to be a recurring issue with very limited parts supplied by GM, leading to potential of very long delays in repair time.

2PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025
Status: closed (inferred from source dates) · Electrical System; Electrical System:propulsion System; Electrical System:propulsion System:traction Battery:management System/energy Control Module (bms/becm)
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.
