Started hearing a ticking noise coming from top part of the engine very next day the spark plug blew out of the cylinder head number 3, resulting in a cylinder head replacement . After reading all of the forum complaints that this is a defect, thank god mine was covered under warranty, still left with out a car for a week , no loaner or ental provided by dealer and I couldnt afford one.
