Following reports last week that GM might have to extend the shutdown of its Bolt EV production until at least mid-October, the company announced on Monday that it has "outlined a comprehensive action plan to ensure that customers can safely and confidently drive, charge, and park the Chevy Bolt EV and EUV," according to a GM press release. Both LG plants at Holland and Hazel Park, Michigan have resumed production and dealer deliveries are expected to begin by mid-October. 

The battery fault that led to a model-wide recall of the electric vehicles beginning in August turned out to be a pair of issues. Manufacturing defects caused both for anodes to tear and cathode-anode separators to fold. Should both of these defects manifest within the same battery cell, it would have a higher chance of catching fire.

"LG has implemented new manufacturing processes and has worked with GM to review and enhance its quality assurance programs to provide confidence in its batteries moving forward," the GM statement read. "LG will institute these new processes in other facilities that will provide cells to GM in the future." 

GM has established a notification process to inform impacted customers as to when their replacement battery modules will be available. The company has also developed a diagnostic software suite designed to "detect specific abnormalities that might indicate a damaged battery in Bolt EVs and EUVs by monitoring the battery performance," per the release. The software has to be installed at the dealership but will enable Bolt EV owners to exceed the current GM-enacted 90-percent charge limit should their batteries pass muster.
