It is indeed a fantastic car. You only ever hear of the very few problems some people have with new cars and never hear of the vast majority of happy motorists!
Having said that, my one goes in for a recall in a couple of days for the charging module. Usually the dealership wants to check the car over after a few months to make sure everything is ok.
They are gonna give the Ioniq a once over, check the module is good and should take 40 minutes. If it needs changing it will take 3 hours.
