I'm not sure if they can reset the maintenance intervals. All the cars I've owned or worked on, those are reset through menus or other means.

Also 100% agree on modern cars. One of my dads vehicles needed a special factory tool to change the sparkplugs. It's complete bullshit.

2014 - it has no dipsticks

That's wild, but it's a problem with specific models/manufacturers, not the entire industry. i have a 2018 car and a 2022 motorcycle and both are pretty maintenance friendly.

Don’t you typically reset the dash lights through codes in the cab? Like, my maintenance light resets by doing something like turning the key five times and pushing a button, I can’t remember because it’s been a few years.
