According to GM, two Chevy bolts caught fire after receiving a recovery repair


General Motors said Wednesday that two recent Bolt EV fires occurred in vehicles that had already been repaired to prevent the battery from igniting and raise new questions; return announced last year. Meanwhile, the automaker warns bolt owners in 2017-2019 not to charge electric cars overnight and park them outdoors if they catch fire.

GM recalled nearly 69,000 Bolt EVs in November 2020 after a handful of reports of fires that apparently started in electric vehicle batteries. The company warned owners at the time to park outside their bolts until it was able to find out the cause of the fires and settle for repairs, but it said nothing at the time about not charging overnight. GM also released a temporary software update that limited the maximum capacity of Bolt’s batteries to 90 percent to reduce the risk of fire.

GM was only in May this year eventually shared his plans to fix the problem caused by the fires. After all, Chevy dealers had to inspect batteries, replace suspected battery modules, and install new software designed to “detect problems with changes in battery module performance before problems can develop.” This software will also be installed on the upgraded Chevy Bolt and Bolt EUV.

Now the problem is that this fix may not work. Two recent fires occurred in vehicles that had received new software and had been inspected by a dealer – including one in a vehicle owned by the Vermont state legislature. Another fire happened this week in New Jersey, the company told CNBC. GM says it will continue to investigate the fires and ask owners who have not received repairs to take the bolts to the dealer regardless. At least nine fires have been documented and the company has started buy back some bolts.

GM has stayed up to date on what causes fires throughout the process, but these bolts from the previous model use the same LG Chem cells that use the Hyundai Kona EV, which is also reminiscent of several fires and canceled directly in South Korea.
