Scotty I have a 2005 Hyundai Tucson. I just hit 100,000 miles never did anything besides change the oil , alternater and brakes. What should I do for maintenance at this milage?
Follow the guidance provided in your owner’s manual.
Given that all the components are aging, I'd shorten the interval for fluid changes -- oil, atf, coolant, power steering fluid, (which you can refresh via a turkey baster, in many cases), brake fluid. None of that is new, anymore.
And preventive test some other components (don't replace them, just monitor, because OEM is often better than any aftermarket) such as the alternator and serpentine belts.
Generally, maintenance of cars is a lot like maintaining people as they older. More attention has to be paid to what used to be taken for granted.
I have a 2009 Kia Sportage as well. The owners manual goes into detail about what you should do. We did the timing belt at 90k miles if you didn't do that yet you should get that done. Other than that, refer to the maintenance section of the manual.
