Well, I just hit over 13,000 miles and my Check enging light came on. Right away I suspected A new head was in my future. I started reading threads on this forum and noticed how many people have been given the run-a-round by their dealer with this isssue.
Dropped off at dealer before they opened for a 2 PM appt on a Saturday. Much to my suprise they called me at about 9 AM with the news. I was in need of a new left head, new lifters on the left side, and they were going to replace the board that runs the radio screen, ( the clock was slow, lost 5 minutes a month).
They said they would need to have the jeep until Tuesday. Heck I think that is not bad. Drop off on Sat. pick up on Tuesday.
Hats off to my dealer - Gator CDJ in Melbourne FL.
