BYD to Update Almost 90,000 Plug-In Hybrids to Fix Battery Pack

BYD Co. will push a software update to almost 90,000 plug-in hybrid vehicles in China after the national regulator said manufacturing defects in battery packs pose safety risks.

The action involves a total of 88,981 Qin Plus DM-i sedans produced between January 2021 and September 2023, according to a statement posted by the State Administration for Market Regulation on Friday. It was initiated after Chinese authorities launched an investigation into the matter.
