I've been very pleased with the reliability of my '12 Power Stroke with 163k miles and almost 7 years old. To date I've had to replace the Nox sensor, all EGT sensors, and passenger side hub all after 100k miles. I had one emission recall flash performed and no safety recalls to date. My engine, transmission, and differentials are all bone dry. Front suspension still has the factory alignment with only replacing the shocks twice.
I consider my Super Duty to be a very economical truck to own.
Having said that I wouldn't mind stock 500HP and 1,010 ft/lbs of torque under the hood. :B
