From what I've found, the Hyundai version is reliable but.... The big issue is that many people expect and even want it to work like a normal automatic transmission; they don't want to "relearn how to drive." So you'll see plenty of complaints about how the DCT operates, that it can be slow from a stop (because you have to ease the power, just like a manual transmission with a clutch, so it doesn't slip), doesn't work properly in stop and go traffic, etc.As the Ioniq has been running for a few years now has anyone found trouble with the dual clutch. After VW problems with their dry clutch I wonder if the Hyundai version is less problematic and what is the life expectancy of the clutch plates.
We have taken ours out to Laughlin, NV this last weekend in the middle of the day at 104 degrees. Ran great, averaged 55.9 for the entire trip and had no issues running through the mountains, in fact it ran better over the mountains than our Elantra GT did!. Its just that there are warnings in the manual about resting the transmission when overheating the transmission messages are shown, particularly when pulling away on a hill or in stop go traffic.
