I hate my 3.5L twin turbo in my 2018 F150. Yes there are maintenance issues: cam phaser, oil leaks, coolant leaks, turbo failure, while at highway speeds it tells me the emergency brake is on, etc. But that isn't what bothers me. I absolutely hate the lag with turbo's. I have almost died more than a handful of times when waiting for the turbos to spool up. Not having instantaneous power is dangerous. If I didn't come from a 5.8L Tundra the turbo's may not be a problem. But when you are used to the instantaneous power and then lose it, well, it sucks. If I had it to do again I would definitely get a 5.0 if I bought a F150.
