Basic Motors stated Monday that it’s going to begin swapping new batteries into Chevy Bolt EVs in October in response to no less than a dozen fires that triggered an enormous recall. GM didn’t say when it’ll restart manufacturing of brand name new variations of the electrical automotive.
The information comes as LG is as soon as once more making batteries for the Bolt after stopping in August. GM says it labored intently with the South Korean conglomerate to ensure the brand new cells are freed from defects which have led to at lest a dozen fires within the automaker’s electrical automobile and an enormous recall.
Homeowners of older Bolts (mannequin years 2017 to 2019) may have all of the modules of their battery packs swapped for brand new ones. Homeowners of newer fashions might solely get particular person modules modified out, GM stated.
GM stated Monday that it’s going to even have sellers begin putting in new diagnostic software program on Bolts within the subsequent 60 days. The software program will frequently scan the battery packs for indicators of defects. If none are discovered, the software program will finally enable homeowners to as soon as once more cost their automobiles to 100%, and abandon a few of the different security pointers GM has put in place whereas it labored out the recall.
The preliminary repair for the recall, introduced in Could, concerned an earlier model of this diagnostic software program, although no less than two automobiles that acquired it nonetheless caught hearth. GM didn’t go into a lot element Monday about how this new software program differs.
Within the meantime, Bolt homeowners are alleged to proceed adhering to that steerage. GM says homeowners ought to park outdoors and away from their properties after charging, and that they need to not cost their automobiles indoors in a single day. Homeowners shouldn’t cost their Bolts past 90 p.c, and keep away from depleting the battery beneath 70 miles of remaining vary.

GM first issued a recall for the the sooner fashions of the Bolt in November 2020 after a handful of fires. However it wasn’t till July of this yr that it introduced what the issue was. In uncommon circumstances, some cells that LG made had two totally different defects — a torn anode and a folded separator — that, when mixed, made it doable for a Bolt’s battery pack to catch hearth whereas charging.
LG shut down manufacturing of the cells in August, round when GM determined to recall all mannequin years of the Bolt. GM stated Monday that manufacturing resumed at two places it runs with LG in Michigan, however that factories in South Korea had been nonetheless not again on-line.
The recall has already price GM some $2 billion. The automaker has stated it intends to recoup some or most of that quantity from LG — although the 2 corporations are working collectively on GM’s next-generation Ultium batteries, and can function a number of new battery factories within the US.
