The engine has high reliability and durability, but fuel consumption is quite high. From 1999 to 2001, there was a defect in the cylinder head, it cracked around the 3rd or 4th cylinder. Many have encountered cracks in the exhaust manifold due to sagging support. On high mileage, the rear crankshaft seal often leaks, and its replacement is expensive.
