2016 Mazda CX-5 with 110K+ miles.
It's still a young pup. Still in fantastic condition, mechanically. Looks like a 20Kmi vehicle. Power windows are a tad slow in the extreme cold, so it's time to re-do the window rails ... and looking for issues while I'm in there. A few paint chips and nicks, here and there, requiring rust-proofing and refinishing those spots. But aside from minor stuff like that, it's running strong.
Preventive measures are what I've always tried to do: stay ahead of the maintenance curve. While I don't believe the maintenance schedule is an absolute, it's a fair guide. That plus usage and a small dose of luck ends up driving what maintenance I tackle. Had the chassis underside and wheel wells coated against rust and corrosion. Have kept up with the fluids, brakes, filters, belts. And I always seem to be doing one thing or another with it.
It's time for the fuel filter. It'll soon be time to replace the suspension shocks, at which time I'll also do the ball joints and tie rod ends. At that point, I'll do the accessory belt again. I keep up with the fluids, brakes, filters, belts. I've swapped the "lifetime" oil in the transmission, diff, transfer case. It's time to clean the throttle body and MAF sensor. Once a few warmer days come along, I'll clay bar, polish and seal the paint. After which, I'll fully clean and detail the interior. And before all that's done I'm sure it'll be time for something else. Everything's a maintenance item at some point, of course.
