Tesla recommends the following maintenance items and intervals, as applicable to your vehicle, to ensure continued reliability and efficiency of your Model 3.
Brake fluid health check every 4 years (replace if necessary)*.
A/C desiccant bag replacement every 4**Â years.
Cabin air filter replacement every 2 years.
Clean and lubricate brake calipers every year or 12,500 miles (20,000 km) if in an area where roads are salted during winter.
Rotate tires every 6,250 miles (10,000 km) or if tread depth difference is 2/32 in (1.5 mm) or greater, whichever comes first.
**A/C desiccant bag replacement can be extended to 6 years on vehicles manufactured between approximately 2017-2021.
*Heavy brake usage due to towing, mountain descents, or performance driving — especially for vehicles in hot and humid environments — may necessitate more frequent brake fluid checks and replacements.
Note
Any damage caused by opening the Battery coolant reservoir is excluded from the warranty.
Note
The above intervals are based on typical driving behaviors and scenarios. Depending on various circumstances such as driving behavior, usage, environmental conditions, etc., the above maintenance items may need to be performed more or less frequently than specified. Additionally, the above list should not be considered comprehensive and does not include consumable parts such as windshield wipers, brake pads, low voltage battery (if applicable), etc.
Note
Damages or failures caused by maintenance or repairs performed by non-Tesla certified technicians are not covered by the warranty.
Scheduling a service visit through the mobile app is easy. After touching Service, select the type of service needed and follow the directions in the mobile app. Provide as much detail as possible to better help the Service team identify the cause of concern, such as:
Photos, sound recordings, or videos.
Date(s), time(s), and time zone when the issue occurred.
Country of use and location.
Approximate speed the vehicle was traveling (if applicable).
Check that all exterior lights, horn, turn signals, and wipers and washers are working.
Check for any unexpected indicator lights or vehicle alerts on the touchscreen.
Check the operation of the brakes, including the parking brake.
Note
Because Model 3 uses regenerative braking (see Regenerative Braking), the brake pads are typically used less frequently than those in traditional braking systems. To avoid the accumulation of rust and corrosion, Tesla recommends frequently pressing the brake pedal to apply the mechanical brakes, which dries the brake pads and rotors.
Check the operation of the seat belts (see Seat Belts).
Look for abnormal fluid deposits underneath Model 3 that might indicate a leak. It is normal for a small pool of water to form (caused by the air conditioning system’s dehumidifying process).
Look around the exterior of Model 3 and immediately remove any corrosive substances (such as bird droppings, tree resin, tar spots, dead insects, industrial fallout, etc.) to prevent damage to the exterior (see Cleaning).
Weekly Checks
During wet weather, clean Autopilot cameras weekly (see Cleaning a Camera). Otherwise, clean them monthly during dry weather.
In addition to cooling the interior, the air conditioning compressor also cools the Battery. Therefore, in hot weather, the air conditioning compressor can turn on even if you turned it off. This is normal because the system’s priority is to cool the Battery to ensure it stays within an optimum temperature range to support longevity and optimum performance. Also, even when not in use, you may hear Model 3 emit a whining noise or the sound of water circulating. These sounds are normal and occur when the internal cooling systems turn on to support various vehicle functions, such as maintaining the low voltage battery and balancing the temperature of the high voltage Battery.
Fluid Replacement Intervals
Battery coolant and brake fluid levels should only be checked by Tesla or a professional automotive repair shop. Specific service information is available in the Service Manual.
Battery coolant:Â Your Battery coolant does not need to be replaced for the life of your vehicle under most circumstances.
Note
Any damage caused by opening the Battery coolant reservoir is excluded from the warranty.
Brake fluid:Â Do not top up your brake fluid.
Software
Updating software is important to ensure proper operation and longevity of your vehicle’s components. You must install a software update at the earliest opportunity. See Software Updates.
Tesla may update or reinstall your vehicle’s software as part of the normal diagnostic, repair, and maintenance process within Service.
