 I've owned 2 Santa Fe's (2001 & 2004). Both had engine failures and had to have their small blocks replaced at around 60,000 miles.  Both failed on the freeway.  Both had all their regularly scheduled maintenance performed by the book.  These 2 freeway failures placed me in very serious safety conditions.  The 2004 failed at night in the middle of the Arizona Desert- I was driving at 70 mph when the engine lost power & made a terrible noise. I end up getting towed over 150 miles to Hyundai Dealer. Small block failed (60,068 miles  68 miles past the warranty).  Hyundai initially refused to pay for the repair; but, after a tremendous amount of effort on my part; they finally cover 30%
