I’ve had my Ioniq5 for almost 2 years and finally did my first longish trip. NYC area to Boston and immediately back. First time relying on DC fast charging and at first was kind of nervous but I can say it was flawless. Went thru two Electrify America stops and got high charge rates both times. Experiences no lines or charging issues at all. Also was free. Will not hesitate to do it again.
It seems non-Tesla charger reliability/availability is very regional dependent. It sounds like the coasts have decent coverage but the middle of the country can be a crap shoot.
I suspect this is why we see Colorado (Out of Spec) and Michigan (Other half of Motor Trend office) based EV reviewers being the loudest about charging reliability problems where as the coastal based reviewers complain about charging congestion.
