Should I stay away from 2015 Fiesta ST for head flaw?

[Vinnyzilla]

I'm going to purchase a ST.

Is it best to get a 2018 Fiesta ST with newer head design or is a 2015 okay if factory recall is performed (band aid fix) and well maintained? I have one in my area that is really clean but it's a 2015 but it does have a lot of cool upgrades and a programmer w a clean title. The other STs I can afford are salvaged but under 100k 2017 and 2019. They all have aftermarket intercoolers and various goodies but none like the 2015 I want to buy with the programmer and multiple tunes come with it.

Is the head flaw enough to push me to choose 2017 or 2018 with the improved head design if salvage is a non issue?

This 2015 has everything tastful and super maintained. Your thoughts?

Thank you in Advance,

Anthony

I have a full bolt on 2015 with over 100k miles. Tuned since 29k miles, big turbo since 40k miles. No issues at all even with the factory radiator. YMMV

What is the head issue you are mentioning? I have two 2016's and so far so good. Both are stock though.

115k on a ’15 here. I’ve done 40k+ miles & nearly a dozen track days on it in the last year. Its tuned for e85 or 91 octane. Just did the timing belt & another ~$5k of major maintenance on it. I wouldn’t sweat the pre 2016 head design at all.

Damn what else did you do?

My 2014 is on 114,000 with NO engine problems. Timing belt done at 107,000 along with other items as a precaution. I'm happy!

I guess I should see if I could explain myself better with the data AI provided me.

I bought a full mod 2017 97k I don't even know what I bought yet but this is loaded. The amount the first owner paid for the clutch assy I was told today I'm sure I heard it wrong but was more than I paid for this ST.

Thank you for the information. That is quite the problem in the head design.

Since I’ve been melting ball joint & caliper boots, all the knuckles, hubs, bearings, studs, inners/outers, LCAs, BBKs

Updating the cooling system seems to cure any issues with the head when driven hard. The car was impossible to drive hard before that, it would get hot climbing hills or sitting in traffic on triple digit days. Radiator & 180 thermostat fix that

Still needs an oil cooler if it’s over 85 degrees ambient for a full 20 min session.

No one actually worries about this stuff. AI is making a mountain out of a mole hill, as usual.

AI can be wrong. These guys in here know what's up real true life facts data. AI can lean towards negative Nancy narratives

The bandaid fix Ford offered to me is so they didn't have to swap out the head I get that.

I'm gonna use my best oil of choice Redline Racing Oil but the seller was Royal Purple guy. I've never used it but I know it's one of the best. I feel ill be changing the oil in a higher frequency over my other Lexus sedan or SUVs type vehicles. There is some considerable heat generated in this ST and that's the root cause of required frequency imo. Chevron 91 and regular Techrolene treatment I'm thinking the norm on direct injection gig I have now. I'm so excited to own a ST.
