“We purchased this 2008 Ford f-250 super duty new at the Ford store in san leandro, ca on july 21, 2007 and continue to be the original owners. This vehicle is equipped with a 6.4 turbo-diesel engine. This vehicle is subject to TSB 07-26-2 (wiring harness defect on hpfp) issued august 2007. On the morning of march 27, 2015, while accelerating onto a freeway and at an approximate speed of 50 MPH, the engine shut down without any warning. I lost all acceleration and the engine died. Braking and steering were also diminished. …”

“When starting my 2008 Ford f-250 I began having to try it more than once, which was very unusual for my truck. Then the next day the check engine light came on. I took it to my Ford dealer, they hooked it up to their diagnostic machine and informed me that the error code indicated that either I or someone else has attempted to modify the PCM (processor) unsuccessfully and that resulted in the PCM being ruined. I assured the service advisor that in no way have I or anyone else done that. He basically called me a liar and said it would be around $1000 to repair. …”

“2008 Ford F-250 SD diesel no warning driving 55 on the freeway towing a trailer the truck shuts down no power. This is the 3rd time this truck has shut down on the freeway with no warning. How can Ford sell their customers a truck as what one other person states: a $55,000.00 truck that is advertised to be super duty and should last 400000 to 500000 miles with only miner engine repairs, this should not be happening. Ford knows for a fact that they have a faulty motor and faulty internal parts on all the 2008 thru 2010 6.4 l diesel motors. …”
