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.

IT IS AN ONGOING ISSUE AND THAT HAPPENS INTERMITTENTLY. WHEN ARRIVING TO A STOP (AT TIMES) THE CAR STILL ADVANCES FORWARD ABOUT A FOOT, EVEN WHEN THE BRAKE PEDAL IS BEING USED AS FAR AS IT CAN. ALSO THE VEHICLE CLAIMS TO BE LOSING PROPULSION, OFTEN, AND SEEMS STRAINED WHEN OPERATING WHEN THE MESSAGE APPEARS.

WE OWN TWO 2017 CHEVY VOLTS. BOTH HAVE TWO ISSUES: 1) OFTEN CRUISE CONTROL DOES ALWAYS STAY ENGAGED DUE TO BRAKE PEDAL SLIPPING TO A VERY SLIGHT DEPRESSED POSITION. 2) SHIFT-TO-PARK- CARS WILL NOT PROPERLY GO INTO PARK SOMETIMES AND THUS CANNOT BE TURNED OFF. THESE TWO ISSUES ARE CLEARLY MANUFACTURER DEFECTS AS BOTH CARS WERE BOUGHT NEW AND WITHIN A MONTH OF EACH OTHER. I WILL ENTER THIS FOR MY OTHER VIN NUMBER AS WELL. THESE HAVE BEEN ONGOING ISSUES THAT WE ARE HAVING TO SPEND MONEY TO CORRECT AND THERE ARE MANY REPORTS OF THESE BEING ISSUES, YET THERE IS NO RECALL. WE PURCHASED BOTH CARS BRAND NEW WITHIN A MONTH OF EACH OTHER. BOTH ISSUES HAVE BEEN ONGOING AND HAVE OCCURED MORE THAN ONCE.

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.
