Good morning, CHARLES OUTCALT JR.,

If your vehicle is still under a powertrain warranty, you should get it from the dealer and keep your receipt. If you end up having an issue with the powertrain or the cooling system in general, you will want proof you put the Hyundai part number into your system. If not, Hyundai might not cover the cost for the repairs under warranty.

Hyundai does say your vehicle takes 50/50 pre-mix of Ethylene Glycol Antifreeze and water. Which is exactly what Prestone Platinum is made with. So technically yes you could use it, but I don't recommend mixing coolant especially if a vehicle is under a manufacturer warranty.

When I worked at Nissan, we had to use the actual Nissan oil, coolant, transmission fluid and so forth part number if the vehicle is under warranty otherwise a warranty claim could be denied.

Hope this helps.

Thank you,
Brendon
