2018 Chevrolet Tahoe — what changed after 100k miles? — buyer question from Westchester

DealPilot472Community StarterMay 12, 20262018 Chevrolet Tahoe LTWestchester
The car has crossed 100k and still drives well. I want to stay ahead of age-related failures instead of waiting for roadside problems. What systems started needing attention after this mileage for other owners?

Owner notes beat generic advice here. On the 2018 Chevrolet Tahoe in Westchester, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “what changed after 100k miles? — buyer,” that was the fork that mattered for me. Not gospel, but it saved me a headache. That's my plan before I call anyone.
