I have a friend with a 2017 Hyundai Elantra GT that blew the engine. The 8th digit on the VIN is "H" vs "F". I can find a variety of "F" coded engines but few "H" coded 2.0 engines. What is the difference? I have done a lot of research with no luck. Vehicle is out of warranty at 61000 miles due to him being a 2nd owner which decreases the warranty from 100000 to 60000..
