Service schedule
All 5 of these items come from Tesla's own published schedule. Manufacturer rows link to Tesla's own schedule, Independent rows to a service shop or parts retailer's published guide.
| Service | Interval | Source |
|---|---|---|
| Cabin air filter Replace the cabin air filter every 2 years to prevent pollen, industrial fallout, and road dust from entering the HVAC vents. | 2 years | Manufacturer |
| Tire rotation | 6,250 mi | Manufacturer |
| Brake fluid Test brake fluid for contamination and general health every 4 years; replace if necessary. | 4 years | Manufacturer |
| Coolant loops The battery and drive unit coolant (G-48 or HTF-LS) does not require scheduled replacement under normal circumstances. | No scheduled replacement | Manufacturer |
| Brake service | 12,500 mi / 1 year | Manufacturer |
Intervals are for normal driving; towing, short trips, extreme heat or dust shorten them. Services we could not find an interval for are left off rather than guessed.
