I work for GM and a 2019 bolt battery will cost you $8500 plus 12 hours of labor at $125 an hour so another $1500 that factor warranty is 8 years/100k miles so it would be awhile before you hit that. There is a huge recall on those batteries due to fire hazard. They tell you not to park in your garage so your house don’t catch on fire. There is a back log on batteries for the recall of about 30k infilled units. There is a major shortage of nickel so the line is moving slow.
