“Vehicle is 34 months old with 47,000 miles. Radiator has to be replaced due to leak in the left front area of the radiator. I know I'm over the regular 3year/36,000 mile warranty, but the drive train warranty is still valid. Ford will not cover it. Radiator should not have to be replaced at this age of the vehicle. Isn't radiator part of engine/drive train? I understand this is an on going problem with these trucks. Ford should at least pay for parts. Thank you!”

NHTSA complaint #11073562, filed 2018-02, 47,000 miles

“Exhaust regeneration causes engine shake and loss of power. The last incident occurred when towing uphill and a semi almost took out the back of my trailer. Ford indicates this is normal, however, it did not do this when new. It occurred after approximately 6,000 miles and continues to happen. The dealer indicated they have not seen this before, so I don't believe normal applies here. If this is normal, then Ford engineers need to go back to school.”

“I have noticed on several instances while traveling on the freeway between 60-70 MPH when the truck goes into regen mode I get a loud valve clatter and a loss of engine power. This could be very dangerous.”

“I have a 2015 Ford f-250 super duty with a 6.7l diesel. I started having this problem intermittently and only noticed it on hot days while at slow speeds, but it has continued to get worse to the point that it happened with every re-gen, at any outside temperature and almost any speed. It all starts with the notification on the screen of clearing the exhaust filter and has an ok in the corner of the screen. Not sure why the ok, since you have no choice on whether to start the process or not. …”

“I was heading from cibolo, tx to kingsville, tx. (distance 181 miles) upon arriving at destination I shut down my truck. After approximately one hour, I started my truck and the check engine light came on. I connected my obd reader and it identified the fault code p21b0 (I did not clear any codes). From my research it relates to the 'reductant level sensor 'c' circuit high'. After researching more information I started looking through the information center under the vehicle setting and noticed the def level was below half (I never got a pop up or notification from the information cluster). …”
