2021 F150 2.7 Ecoboost Lariat

I just bought this with 64k miles. It was a certified with just a 6 month powertrain warranty. I actually got it about 4k below book. Anyway, they're offering me a 3 year 36k bumper to bumper warranty through Ford for about $2,900. Is that worth it? I can afford pretty much any repair, but the finance manager was talking about all the electronics and how his wife's f150's engine had to be replaced at 47k miles. From what I've been reading, the 2.7 seems to be a solid engine. I usually only keep cars about 2 or 3 years and have never had an issue that would cost me more than $2,900.
