Yes, repair under Warranty as there's no way Honda could apportion blame to ANY rapid charge provider, a rapid charger is a rapid charger at the end of the day.
I have used CCS regularly in the time I've owned the Honda e, using numerous charging providers, without any issue whatsoever.
The red light of doom at the charge port appeared when I ended the charge using the Tesla App, and before I'd unplugged. The Honda e clearly wasn't happy with something; only time will tell if this will be a recurring issue for Honda e owners.
I shall be steering clear of Tesla Superchargers for the foreseeable future, it's a shame but such is life.
