– A failure of the Chevrolet Volt battery energy control module caused the National Highway Traffic Safety Administration to open an investigation in November 2023 after the agency received at least 61 complaints.
These complaints indicate that in 2016-2019 Chevrolet Volt cars are stalling, losing power, and sometimes not starting due to a failure of the battery energy control module.
The BECM is located in a high-voltage electric vehicle battery pack and should monitor the voltage, current and temperature of the battery.
NHTSA knows that GM has issued a technical service announcement for the 2016-2019 Volt BECM failure (TSB 18-NA-261). The government knows that module failure causes these diagnostic fault code settings: U2603, U2604, U2605, U2606, U2617, U2617, U2618, U2619, U2619, U2621, U2621, U2622, U2622, U2623, U2623, U2623 and U2624.
GM dealers were told that internal battery energy control module problems could be fixed by replacing modules.
NHTSA has closed the investigation as General Motors released its special underwriting plan for Chevrolet Volts in March 2024 N232432680 for March 2016. Clients were notified of the plan and how BECM would offer warranty extensions from 8 years/100,000 miles to 15 years/150,000 miles.
General Motors noted that battery energy control module replacement will not fail and will come from other suppliers.
According to NHTSA, if things change, safety regulators may reopen investigations.
