only about 45,000 on it . Great Running except , when at a light in gear or in neutral after the car is running a while , the engine is making a sound that is reminiscent of a washing machine . It is something that sounds like a repetitive noise every few seconds . Annoying and disconcerting. Dealers mechanics say it is normal, I do not buy it. Has anyone else experienced this noise ??? Any suggestions as to what it could be ?
