I don't think Ford's issues are engine specific. My 2019 5.0 has been in the shop 42 days this year. It's been in for more unscheduled repair visits in 33,000 mi than my previous 5 vehicles in a combined 250,000+ miles. Nothing catastrophic, except for that one rainy morning where the entire dash and everything controlled by it failed...no horn, no wipers, no headlights, no tach or speedometer, no radio, no ability to change climate control settings or defroster. It threw trouble codes for every major module; the dealer reset the modules and called it good. A couple months later it started throwing codes for running rich. At first it was intermittent, then steady. It turns out the truck wasn't sure what kind of fuel was in it - it thought the fuel ethanol content was 60%+ (I've never run e85). Once again, the solution was to reset a module. It just seems like Ford has some real QC issues in recent years. I still like the truck and think the F150 is a terrific platform for our use, because unlike so many manufacturers, Ford doesn't limit a lot of key hardware options to specific trim levels or packages, giving the user the opportunity to truly customize their truck for their usage. However, after this recent experience, I'm seriously considering whether or not to replace this truck, maybe with another F150, maybe with a current generation Tundra. All manufacturers build a problem child every now and then; some build more than others.
