Loss of motive power due to the battery energy control module. Closed mar 3, 2025.

NHTSA summary
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 ce

Pedestrian alert sounds. Closed aug 7, 2023, led to recall 22V-063.

NHTSA summary
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.

Post-crash ev fire hazard. Closed jan 20, 2012.

NHTSA summary
The subject vehicles, which employ emerging technology, are range-extended electric vehicles that utilize a high voltage (HV) battery to provide energy for propulsion. The HV battery is lithium-ion based technology that has a nominal full charge of 390 VDC, a 16 kWh capacity, and a control system that incorporates liquid (antifreeze) cooling and various electronic devices (control modules, sensors, wiring, etc) to monitor and manage the HV battery. The HV battery, portions of the cooling system, and the control system are contained within a common enclosure.During an NCAP oblique side pole impact test conducted by NHTSA in May 2011, the pole struck and deformed the sill plate under the driver's door at a location where there is a structural member. The lateral member displaced inward, pierced the HV battery enclosure and battery, and caused a battery coolant leak. Thereafter, the Agency conducted a rollover test (the rollover test consists of four 90-degree rotate-and-hold movements about the vehicle's longitudinal axis). In that test, the HV battery and electronics were exposed to coolant that leaked as a result of the crash. The vehicle fire that occurred three weeks later and the additional testing NHTSA conducted are discussed in a report titled 2011 Chevrolet Volt Battery Fire Incident Report a copy of which is available in the public file. The report indicates that intrusion induced coolant leakage, and subsequent rollover that saturates electronic components, were the

What owners wrote

“2018 Volt will not shut off. Shift to Park displayed on console. Problem has been diagnosed at dealer. Problem is under Service Bulletin 19-NA-206, Voltec (Electric and Hybrid Vehicle) Warranty. Dealer and GM refuses to repair. Problem has been occuring for several weeks.”

“When car is put into park, system does not show vehicle is in park and will not shut off. It takes multiple times of pushing the start button and moving the gear shift back and forth before the car finally realizes and confirms the vehicle is in park and will turn off.”

“Vehicle displays "shift to park" when it is already in park, and will not shut off. I had to leave it on, and despite nothing apparently on (electric vehicle, no motor running), it drained the12 volt battery and would not start up the next day.”

“When car is stopped and shifted to park a message comes onto the dashboard telling me to Shift To Park. The car does not completely shut off nor do the lights, and you can not lock the car.”

Should you keep driving it?

This page can't tell you that. 0 of 55 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
