I have a 2017 Tesla Model S (100kwh). I had my first maintenance issue this year. The 12v battery needed replacing (it runs the aux systems, just like an ICE vehicle) but didn’t keep me from driving while it was sending the error code. 107k miles and it’s mostly been wiper fluid, wiper blades, and 2 tire changes. I need to replace my windshield, but electrically and mechanically speaking… no major issues.
