I have the 2018 GT and the only real issue I have had with it was the tires. Mine had about 22,000 miles on it when I bought it.I am a daily commuter so now it has 44,000 miles on it. I also bought it used re certified. Mine has the black interior and it seems to take a long time for the AC to cool it down inside. I can tell it's working ok because I feel the cold air. I attribute it to simply all of the heat when I get in it.
I wasn't aware of the fuel pump issue. If I were buying the 2018 I would make sure the latest software update is installed ( should be with a re cert car). I put in car play myself. The 2019s and onward already have it I think.
I guess only you can decide on your budget. Cars are gradually going to be going more electric and I see a pivot point in about 5 years as I am told battery tech will be much more advanced by then. I think it's still too early to buy an EV for me. This is only my opinion."IF" I were looking at a 2022 though, I might at least consider a hybrid. You could go from 28mpg standard CX-5 to low 40's mpg average with a hybrid small SUV.
If I'm dropping that kind of money and a hybrid equivalent exists for not much more, it would be a consideration(for me).
