My car has been really reliable since new but I've recently found myself doing a lot more maintenance on it because it's no longer a low km car and it's also getting a bit older now (7yrs old). Here are some things I look for when I have it on a hoist. Most of the items are related to reliability of the engine and drivetrain so that I won't get stranded on the side of the road. Some are nit-picky things I do to keep my car in tip top condition. Others are stuff I check because there are known issues w/ those components.

Notes:
- I didn't bother listing anything that can be checked from inside the car while driving. This is a list of stuff to check because these things can't be done from the driver seat.
- I didn't specify fluid change intervals because my list is just a checklist that I use to supplement the honda maintenance schedule.

7th gen maintenance check list:

Fluids (check levels, color)
Battery (load test, signs of cracking, fluid level, terminal corrosion)
Compliance bushings (signs of cracking)
Struts (leaks, cracked dust boots)
Brakes (pad/shoe thickness, rotor/drum thickness, fluid leaks at caliper, brake line damage)
Vacuum hoses (signs of cracking)
Motor mounts (rips or signs of cracking)
Air filter
Axles (torn or leaking dust boots)
Door hinges & door checker (grease hinges & door checker)
Exhaust manifold (signs of cracking)
Engine (noise, oil/fluid leaks, oil sludge seen through oil cap, spark plugs, drive belt damage)
Radiator (cracks on radiator, cracking hoses)
Lower ball joint (excess play)
Tires (cracks, punctures, uneven wear, air pressure)
Exhaust (rust)
Sway bars (worn bushings)
Endlinks (broken or excess play)
Headlights (oxidation, aim, melted harness)
Tie rod ends (check for play, torn dust boots)
Micron air filter (clog ones could cause the a/c transistor to overheat)
OBDII scan (just to see if there are any pending codes or abnormal sensor data)


feel free to add anything i missed...again, the list is mostly for stuff that can't be checked/noticed while driving the car.
