 My 2004 PSD F-250 has been in repair for 50% of the time with transmission and accelerator control problems, including an accident caused by loss of accelerator control.   It has had a new wiring harness, two new computers, a rebuilt transmission, new accelerator pedal, engine sleeve, and other issues, and now needs a new transmission that Ford says will take 70 days to deliver.  My F-250 SD has been a nightmare to own, and Ford has been virtually non-responsive to my complaints. Their customer interface stinks, to but it nicely.  I almost never tow with this truck, never take it off road, and never abuse it, yet the transmission failed three times. Once minor, twice major.
