I hope you're right about that, but these reports of Bolts catching fire have been in the mainstream news. I'm no GM fan either but I want to see public acceptance of all EVs and from afar, the Bolt looked like one of the best EV values out there. Even though this isn't applicable to the current year's model, people shopping the new Bolts will be aware of what happened with the older models and many of them will feel like it's too risky to trust GM with a battery powered car that they want to charge in their own garage.
Like the ignition scandal from just a few years ago, this is potentially another PR black eye for GM and this time it's kind of a shame. LG made those batteries, not GM, and they deserve some of the blame for this.
