 At 75,000 miles had the spark plugs and timing belt replaced at a cost of $900! The intake manifold has to be removed to get at the spark plugs and the timing belt is very difficult to get to. There could be two reasons for this: 1) Thoroughly incompetent engine design engineers, or 2) Hyundai management dictated poor design for maintainability as a way of enriching their dealerships.  The unfortunate owner has to spend a lot of money for what should be simple and inexpensive replacements. Spark plugs at least should be a do it yourself project. And then there are those engine and cruise control glitches; my Santa Fe seems top have more glitches than the space shuttle.
