Hi folks. I’m looking to buy a 2018 F-150 diesel. Any owners here with high mileage on your truck? Say above 125,000 miles? What has your experience been as far as reliability? What are the common failure points?

I have an idea how the F-150s last but what about the 3.0? Thanks in advance!

There is a guy on youtube with a channel called ArmyProperty. He is an expediter who added a diesel F-150 to his fleet. He recently posted a 5,000 mile review, and is racking up 1,100 miles/week. So in two years you will probably have your answer.

There is also this thread:

I have a 2019 with 160,000 km so 100,000 miles. Have literally done nothing to this truck other than oil changes and fuel filters. Have owned 5 different F150s with the 4.6, the 5.4, the 3.5 and the 2.7. This is easily the best engine. I cant figure out why Ford didnt push them a little harder and discontinued them. At my dealer it was like they didnt even exist.

2018 with 78k. Just had the little rubber seal that lives in the oil cooler below the cartridge filter break and move causing low oil pressure at low RPM. Ford said it’s not a warranty part and said $2,000 parts and labor. If you don’t have this issue now, you probably will and the four dealers around me didn’t have a clue. I found it on a forum and brought it to their attention.

Ahh, you have been bitten by the nub. If you haven't read it yet take time to read all about our experiences with your issue. Sadly there is no easy way out since no one sells the $1.50 part that needs to be replaced.

Read this thread Here

There are several threads about this but I think this one covers it best.

Of note is that whoever changes your oil caused the breakage. In my case it was me. It is a case of Read The Manual! which obviously I didn't and neither did your mechanic. By the way, welcome and hopefully your future posts can have better reports, this one is certainly a downer but you are in good company.

Yes, and it probably was me. Hard to say because I go back and forth from having ford do it when it’s in for a recall or something trivial and myself when I don’t have time to sit at Ford for three hours. I’d love to know if anyone gets somewhere with Ford on a recall or better solution than $2,000…
