 I have a 2011 F-150 3.5 twin turbo Eco Boost, I bought it with 50,000 miles from Bob Maxey Ford dealer in Detroit Michigan in 2013. It cost $29,000 I thought I had something.  It road good for the first 6 month. I mad sure I kept my oil change because my brother have the same vehicle and had problems with his Timing chain which was costly.  In November of 2015 my Truck stopped and would not run in the middle of Southfield Rd, Southfield MI, so I had it towed to Avis Ford.  They wanted $1945.00 to diagnosis the engine because they could not till me what was wrong from the initial survey.  I called Ford customer service because my warranty was over after 60,000 mile.  I only had a little over 100,000 mile on this Built Ford Tough Truck.  Ms. Jane stated that Ford would have nothing to do with the tear down of this truck and they may help me if I took it to a ford dealership.  I went to the Veteran Administration for monetary help, and tried to qualify for their trust funds, they recommended several auto shop but I did not qualify. They said that I could afford to pay for my repairs.  I has this truck towed to AAMCO They gave me a good price of $2388.00 for labor and parts, there is a Technical Service Bulletin on the Truck TSB1 and TSB2.  Ford is very aware of the problems with the Timing Chain on this make an model of this truck.  AAMCO repaired the timing chain issue and did a pressure test only to find that the pressure on cylinder 2 3 6 was 65 70 70 and should be 130 in order to be in spec.  Now the head has to be sent to a shop for repair and the 4 valves per cylinder replaced.  at least another $1500.00. I am hurt.  paying on a Ford truck that broken down on me and my 13 year old son and I must still pay the truck note. I am communicating with Ford customer services but will not receive and help because it is not a Ford dealership.  I am pissed because Ford Motor Company knows about this timing chain issue, they have a TSB explaining this issue, and this may cost me $4000.00 that I don't have. Built Ford Tough!!!!
