A mixed bag!
Overall in the day to day the car is fantastic. We love the way it drives, how comfortable it is and at sensible highway speeds it is pretty efficient.
However, we have been very disappointed by the number of recalls and the major issues with the ICCU. We had this fail, stranding us while on holiday, and while a "local" Hyundai dealer was able to fix the car in 5 days we were unable to claim the cost of a rental, Hyundai simply denied the claim... When the car was towed to the dealer we were reassured a replacement car or rental would be covered as the ICCU failure was a manufacturing fault. We are now very worried the ICCU might fail again and strand us somewhere with a new born baby!... Very disappointing for a brand new expensive car. It makes it very hard to recommend to others.
The lack of clear communication from Hyundai on this issue is also frustrating! It seems like the recalls have simply replaced ICCUs with the same unit again so we have no confidence it won't fail in the future.
In addition to the above it is very hard to get an appointment at a Hyundai garage so services and recalls take ages to get sorted.
We also really struggled with the NACS adapter (we still haven't received one...) Having to ensure one hidden button is toggled on the website was annoying at first, then the email came through with an old address despite Hyundai having our new address for other post. We then couldn't update our address on the website, and multiple requests to customer services didn't get a reply or a resolution. It would have been better if you'd simply let people buy them from you at low cost rather than go through this annoying performance. The logistics must have cost Hyundai a fortune!
Finally having to use the Hyundai maps for battery preconditioning is frustrating to the point we don't use it. The maps are often out of date, don't know the latest traffic and it is very hard to put in the correct charging station to activate the preconditioning. There needs to be a way of using preconditioning and Android Auto! We would switch car brands for a feature like this in the future.
