the timing Chain tension broke on my 2006 Mustang with 68,000 mi. Ford will not warranty the problem, I believe that a timing chain assembly should last longer than 68,000 mi.
Ford has the ability to assist in the cost of the repair but they declined the me and dealer, livermore ford. Prior to this problem, the transmission had to be replaced at 40,000 miles. Sounds like a quality issue with the particular vehicle. I had a 2000 Jeep grand Cherokee with 165,000 and never had a problem other than normal maintenance.
This is the last Ford product I'll purchase, buyer beware.
