Hi. I believe your Hyundai has a blown head gasket. This failure mode may not contaminate engine oil with coolant as sometimes occurs. The lost coolant may go into the cylinder or the exhaust instead. A slightly sweet smell from the exhaust pipe, with or without white smoke/steam would confirm this diagnosis. A certified technician from YourMechanic can come to your car’s location to inspect the overheating problem and pinpoint any faults that need repair.
