Some of these issues are also true with EVs. I’m not sure where you live but around me chargers are very often out of order, or vandalized/stripped by drug addicts, or don’t charge at the advertised rates. It is far worse than what I gather the experience is for hydrogen.

I didn’t have maintenance issues other than minor ones, but I do have friends who had their EVs in the shop for several months at a time. Tesla was nice enough to provide replacement cars but I’ve not heard of months long issues for typical gas vehicles (outside of pandemic supply chain problems).
