 Bought used at 40k mi. Engine lunched at 115k. If you buy or own, change the darn timing belt @ 70k. Belt is made of pressed fiber of some sort. The Korean v6, unlike American v6, is an interference engine - meaning if the timing belt goes, the pistons and valve beat the engine to death - unlike a non-interference engine. We run Mobil one synthetic from day one. We have two American cars - both v6 - one at 180k the other at 225k. Never changed the timing belt. Both run. The xg350 had a rattle in the driver side trunk. It cruised smoothly and easy on long trips but about as much fun to drive as an Abrams tank. Do not recommend and will never buy another Hyundai. Your mileage may vary
