Sounds unnecessary. I’d put a can of Seafoam in the tank to clean the injectors though.
You're right to be suspicious. The warranty is based on the manual's recommended service items. Anything else is the dealer trying to get you to pay for added maintenance. If it is not a recall or service bulletin item I would not get it.I have a 2020 model year bought new in March ‘21 with 28K miles.
I just took it in for an oil change per the oil life sensor and the dealer rep is recommending a fuel system service that costs $400ish “because it’s recommended at 25k” as well as a bunch of stuff at 30k.
I looked in the manual and it says nothing except an air filter change at 30. Dealer rep says “yeah but it depends on where in the country you are,” sounds like BS to me but New England is hard on vehicles.
Truck runs fine and I only put top tier gas in it. I did buy Ford extended warranty and I’d usually assume that they’d require anything that matters to retain the warranty. I don’t mind spending money to maintain properly but I get suspicious when I see stuff like this.
