The cars are young, so failure data is thin, but a few themes recur: the air suspension can feel stiff in Dynamic and is a long-term cost item (the GT switches to coilovers); carbon-ceramic brakes are a spec to confirm; and tunes/exhaust mods can void warranty. Importantly, low miles do not guarantee health — at least one abused, tuned example showed bore scoring with almost no mileage, so an inspection still matters.
