According to Electrek, GM has knowledgeable some Chevy Bolt EV homeowners that it’s going to exchange all of the modules of their batteries with new ones. This is the most recent step the automaker has taken to handle points in some Bolt EV fashions that make their batteries extra prone to catch hearth. As the publication notes, GM has recalled the Bolt EV twice in a little bit over a yr earlier than this and after over a dozen incidents whereby the car went up in flames because of battery-related points.

That warning got here after two Bolt EVs caught hearth within the US. Finally, in April, the automaker launched what’s supposed-to-be the ultimate software program repair for the difficulty. Clearly, that wasn’t capable of fully resolve the issue, and GM needed to discover one other answer.
Electrek says GM has knowledgeable some homeowners that they will be capable of begin reserving appointments to have all of the modules of their batteries changed beginning on August twenty third. Owners who undergo with the substitute may even get a brand new 8-year 100,000 mile guarantee.

Based on the autos that caught hearth, Electrek says GM will seemingly prioritize 2019 fashions adopted by 2017 and 2018 fashions. The firm may even exchange modules for homeowners who routinely do deep discharges.
GM instructed the publication that they are taking this step “out of an abundance of caution.” Further, GM and LG (the battery’s producer) will look at the changed modules and discover their defects. They’ll additionally attempt to determine if they will devise an in-situ detection technique that will enable homeowners to determine if their batteries are liable to catching hearth.
