The National Highway Traffic Safety Administration (NHTSA) has announced an investigation into Chevrolet Volt plug-in hybrid cars due to reports of power loss and other issues. The investigation covers model years 2016 to 2019, and focuses on the battery energy control module (BECM). Some drivers have reported a sudden loss of power without warning, while others have experienced reduced power mode. The NHTSA has stated that if affected vehicles are unable to move with the flow of traffic or cannot be restarted, it could pose a safety risk.
According to complaints received by the NHTSA, some Chevrolet Volt owners have faced delays of several months in obtaining replacement battery modules. General Motors (GM), the parent company of Chevrolet, has reassured that it has an adequate supply of replacement parts. However, some owners have expressed frustration at being unable to obtain the necessary replacements.
GM previously issued a technical service bulletin suggesting that if a vehicle fails to restart, the BECM may need to be replaced and reprogrammed. However, the company has not yet issued a recall for the affected vehicles. GM has stated that it is cooperating with the NHTSA's investigation and has taken measures to address customer concerns related to the battery energy control module.
The Chevrolet Volt, a plug-in hybrid, was discontinued by GM in early 2019. The investigation by the NHTSA is ongoing, and GM has pledged to support the agency's review of the matter.
In summary, the NHTSA has launched a preliminary investigation into Chevrolet Volt plug-in hybrid cars due to reports of power loss and other issues. The investigation focuses on the battery energy control module and its potential impact on vehicle safety. Some owners have experienced delays in obtaining replacement parts, while others have expressed frustration at the inability to restart their vehicles. GM has stated that it is cooperating with the investigation and has taken steps to address customer concerns.
