This has been the best car I have ever owned however at 120,000 miles the camshaft sprockets began to make terrible noise on cold start. I had them replaced but the engine had to be torn apart to get at them. I have changed the oil every 3,000 miles and take care of this car like a baby. It shouldn't have happened and even the dealer said as much. Unfortunately the warranty was long over and it cost me $4300. These sprockets had extruding bolts on them and the replacement sprockets were redesigned without the large bolts extruding. Has anyone else experienced this?
