Brake pads OEM Subaru or Tesla

my 2015 Model S is still on the original brake pads, never had an issue, and I'm at like 125k miles.

Several teslas, both S and 3, and never had to replace them. I got used to one pedal driving. My 3 has almost 60k and brakes are almost new.

2014 MS P85D 102,000 miles still on factory pads and rotors.

I have about 50k miles on my 2018 M3. Pads still seem to have plenty of life left.

I’m my 2019 Forester, I hit 70k miles without changing either fronts and rears. The fronts now need to be done. Hard to argue against OEM with that performance.

I was hugely disappointed, because the pads are great. TBH, it's basically a low- to mid-tier race pad, so the price is not that ridiculous. I put quite a few track days on them and after trying out some other aftermarket pads, I actually went back to the OEM pads for 3-season street use.

I as well just replaced the oem brakes after almost 7 years. Other than a warrantied sensor, I've not had any issues. Still a blast to drive after 7 years, it still feels new.

What type of maintenance do they need? Can you get parts for them (say brake pads) easily?

The brake pads suck.

IMHO, the brakes are also awful.
