Anybody had any problems with the cylinder head cracking, my 3.0 V6 started puffing smoke from the engine compartment, had it looked into and the head is cracked. As you look into the engine bay it is the one on the right. I have logged it with customer care that are looking into it, they have informed me they will talk with the dealer and then with the technical department and get back to me with their outcome. The car is out of warrantee but with full dealer service 4years 4 months old, 70,000 miles, light use only most of the time only me in the car. I did not expect this to happen. Does anybody have any thoughts?
