NHTSA Complaint #11710743 — 2008 FORD F-350

I have had multiple incidents of my truck shutting off completely while driving. The latest incident resulted in a "catastrophic engine failure". In the latest incident occurring in April 2025, I was driving on [XXX] . [XXX] is a two-lane highway with no divider, navigating through mountainous terrain. I was driving up a hilly area when my truck shut off, and I lost all power steering. There is no shoulder on this part of the freeway, with an approximate 40-foot embankment. I was able to navigate the vehicle to the side of the road and position it just before the beginning of a guard rail beginning allowing me some grace. Due to no shoulder space, I was effectively parked on the white containment line of the road. I had my [XXX] daughter and wife in the car. I had to wait for a break in traffic to be able to open the driver's door due to the proximity to the active highway. I was safely get the truck towed to the nearest FORD dealership, where it was determined the engine was in "catastrophic failure" due to oil engine overfill. I informed FORD that my last oil change was with the FORD dealership and within the recommended time frame. I was informed by a technician that there is an ongoing issue with this engine make (6.4-liter, diesel). The technician stated that FORD is aware of the issue. The technician stated that fuel gets mixed with the oil and causes an "engine oil overfill". None of these issues stems from negligence but rather an unakknowledged issue by FORD. There was a check engine light that appeared at the time of failure. The check engine light had come on, at which point I contacted a mechanic to schedule an appointment. When I arrived for my appointment, the check engine light had disappeared, and I was told that no codes would alert if the actual check engine light was not on during the inspection. That same scenario occurred on approximately 3 occasions. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
