Not a Santa Fe, but a 2011 Sonata with the same 2.4L engine. Died at about 62K miles and was replaced free of charge by Hyundai

. Took about 5 weeks for the replacement -- this was about 4 to 5 years ago, and I believe
lots of engines were failing. During the down time, Hyundai provided a free rental vehicle (Mazda) which had lots of features the Sonata did not have. We continued to drive the Sonata without issues for about another 6K miles, but all the time thinking about those Mazda features, especially "blind spot detection". We then found a used (10K miles repo) 2017 Santa Fe Sport
with those features and more, bought it, and sold the Sonata. The purchaser was happy to get a car with only 6K miles on the engine; I think that actually
increased the value of the Sonata...
