“This is totally dangerous I could've lost my life period I'm on freeway and my wheels just started sticking and my car was smelling like electricity or electrical fire so I go google of course and youtube low and behold recall on bad fuse boxes on theses particular cars”
NHTSA complaint #11319102, filed 2020-03, 109,000 miles“I am reporting this because I see other models with the same engine having the same problem. My valve cover gasket leaked oil onto the alternator and caused it to fail prematurely. This has happened in april of 2014 and has now happened again in june of 2015. Other models utilizing the same engine have been recalled due to this problem. Will this model be recalled?”
NHTSA complaint #10731138, filed 2015-06, 80,000 miles“This car has the front valve cover gasket leak that other Hyundai vehicles with the v6 engine. It only leaks right in the same corner as all the others and it leaks right on to the alternator. I am on my second maybe third alternator. I ahve been lucky enough to have it not cause any injury's so far.”
NHTSA complaint #10903837, filed 2016-09, 120,000 miles“Oil leak from valve cover gasket dropped on alternator. Damage to alternator caused vehicle to shut off while going 60mph on an interstate. Multiple lights on the dash illuminated (including the engine and battery lights, the seat belt light started flashing), I lost power to the radio and the lights inside the car stopped working, quickly after these two issues started I lost the ability to accelerate (again, while going 60mph on an interstate). …”
NHTSA complaint #11184175, filed 2019-03, 140,000 miles“Valve cover leaks onto alternator, can cause sudden power loss and premature alternator failure. I've been researching this issue and other people have had this exact thing happen. Apparently once you get the valve cover gasket fixed, it will fail again in another year or so. There is a defect either in the gasket or the valve cover mating surface. Currently my car is only at the stage of oil leaking from cover gasket and getting onto the alternator. No further failure has happened yet. My car has 67,000 miles.”
