Tesla Model 3 Parts, Specs and Maintenance Guide

The Tesla Model 3 is the car that made EVs mainstream in America, and from a parts-and-maintenance standpoint it splits cleanly into two eras. The original car (2017–2023) launched as a Long Range RWD sedan and grew into a three-powertrain lineup, single-motor Standard Range/RWD, dual-motor Long Range AWD, and Performance, picking up a heat pump, powered trunk, and double-pane glass in the 2021 refresh and an LFP battery on the base RWD in 2022. The 'Highland' refresh (2024–2025) reworked the body, suspension, and interior but kept the same service items.

There is no engine oil, no spark plugs, and no dealer service schedule. Tesla's official list is just tire rotations every 6,250 miles, cabin filters every 2 years, a brake fluid health check every 4 years, and winter brake-caliper cleaning. What owners actually look up: the 12V battery gotcha (cars built through roughly November 2021 use a small 85B24LS lead-acid battery that dies every 3–4 years; later cars use a lifetime 16V Li-ion pack), tire sizes and the universal 42 psi placard pressure (heavy EV + XL-rated tires means fast tread wear), the two-stage cabin filter replacement behind the passenger footwell, and a recall history that is almost entirely fixed over-the-air, window pinch (22V-702), heat pump software (22V-050), TPMS light (24V-935), plus the long-running phantom-braking complaint file (NHTSA PE22-002, closed without a defect finding).
