Check charging system and check brake light came on at 76000 miles driveing 65 MPH in the highway after 3 hours. Collant did not read hot, battery read dead. Vehichle quickly decellerated and I pulled over. Radiator blew neck off and several components of the cooloing system and hoses were melted there is a strong smell of fludge/fule based residue/combustion in cooling system that blew off neck. Battery so week I could not use the key to open a door or the trunk, or move seats. Coolant had just been topped of and system was flushed within 10,000 miles. Mechanic at kia dealership diagnosed tgat tge gead gasket/cylinder head leaded into the cooling system causing the neck to blow off the radiator and melting several sensors and components of the cooling system that would not have melted or blown from fumes of low coolant alone. Oil levels and quality was good. I photographed the dash lights at breakdown and the coolant levels did not read hot. Check charging system and check brake lights came on. Check brake lights check engine lights had been a problem before. Dealership for hyundai (coggins hyundai in deland) says they think a lack of coolant caused issue, but I know I had coolant in the car - they just want to not be responsible for warranty repair,as I am the first owner and have done proper maintainance. I have seen many other people complain of similar issues from when the car is new (check chargins system less than 3000 miles) and the car blowing up/catching fire, etc. Perhaps the reason mine did not catch fire was all the coolant that was released. One car owner insists that all hyundais will do this between 70,000 and 100,000 miles. Something big is going on with these cars - mine has had continual problems and it should be replaced at huyndai's cost. This should be studied further! Safty hazard!
