We'll see more data on this when the bZ4X actually hits the road.
EVs are a new technology with questionable reliability. Currently, there is a 10-year/150,000-mile battery warranty requirement on plug-in hybrids thanks to California but nothing on battery electric vehicles. Hopefully, this will change soon and a 10-year warranty on EV batteries will also be required. OEMs are fighting it hard, as a battery costs $20,000 or so, making the vehicle a total loss when the battery fails. I remember in the 1990s, junk yards were full of brand-new-looking Hyundai Excels because they were so unreliable and it was not worth fixing their drivetrains when they failed. Don't be surprised if the junk yards are full of Hyundai Ioniq 5's in a few years from now. Toyota has the right approach by being conservative with battery charging.
EVs are far from new technology, but those without a track record or have a poor track record so far should be considered questionable.
