Have you checked the manual, which has a specific section in it with the answer to this question (this is a rhetorical question, since if you had checked the manual you likely would not have created this thread).

Maintenance Service Intervals
Service Intervals
Your vehicle should generally be serviced on an as-needed basis. However, Tesla recommends the following maintenance items and intervals, as applicable to your vehicle, to ensure continued reliability and efficiency of your Model Y.
For more do-it-yourself maintenance procedures and information, see
Do It Yourself Guides | Tesla Support.
For more information on vehicle alerts, see
Troubleshooting Alerts.
- Brake fluid health check every 2 years (replace if necessary) or, if the vehicle is used for towing, replace the brake fluid every 2 years.
- A/C desiccant bag replacement every 4 years.
- Cabin air filter replacement every 2 years (or 3 years for HEPA and carbon filters, if equipped).
- HEPA filter replacement every 3 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
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. However, Model Y should generally be serviced on an as-needed basis; depending on various circumstances such as driving behavior, usage, environmental conditions, etc., the above maintenance items may need to be replaced 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 lead-acid 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.
Schedule Service
Scheduling a service visit through the mobile app is easy. After touching Schedule Service, select the type of service needed and follow the directions in the mobile app. Provide as much detail as possible, 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).
- Environmental conditions (rain, snow, cold, etc.).
- Road name and type of road (if applicable).
- Quality of lane markings (if applicable).
- Applicable vehicle settings.
- Identifiable symptoms.

Daily Checks
- Check the Battery’s charge level, displayed on the touchscreen or mobile app.
- Check the condition and pressure of each tire (see Tire Care and Maintenance).
- 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.
- Check the operation of the seat belts (see Seat Belts).
- Look for abnormal fluid deposits underneath Model Y 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 Y and immediately remove any corrosive substances (such as bird droppings, tree resin, tar spots, dead insects, industrial fallout, etc.) to prevent damage to the paint (see Cleaning).
Monthly Checks
Note
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 Y 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.
Warning
Contact Tesla immediately if you notice any significant or sudden drop in fluid levels or uneven tire wear.
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: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: 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.
High Voltage Safety
Your Model Y has been designed and built with safety as a priority. However, be aware of these precautions to protect yourself from the risk of injury inherent in all high-voltage systems:
- Read and follow all instructions provided on the labels that are attached to Model Y. These labels are there for your safety.
- The high voltage system has no user-serviceable parts. Do not disassemble, remove or replace high voltage components, cables or connectors. High voltage cables are colored orange for easy identification.
- If a collision occurs, do not touch any high voltage wiring, connectors, or components connected to the wiring.
- In the unlikely event that a fire occurs, immediately contact your local fire emergency responders.
Warning
Always disconnect the charge cable before working underneath Model Y, even if charging is not in progress.
Warning
Keep your hands and clothing away from cooling fans. Some fans operate even when Model Y is powered off.
Warning
Some fluids (battery acid, Battery coolant, brake fluid, windshield washer additives, etc.) used in vehicles are poisonous and should not be inhaled, swallowed, or brought into contact with open wounds. For your safety, always read and follow instructions printed on fluid containers.
Replacing the Low Voltage Lead-Acid Battery
This procedure is intended for vehicles in North America only.
CAUTION
To avoid damage that is not covered by the warranty, replace your low voltage lead-acid battery with the same type of battery. The low voltage lead-acid battery for North American vehicles is
AtlasBX / Hankook 85B24LS 12V 45Ah. You can purchase a new lead-acid low voltage battery that is compatible with your vehicle from your local service center.
Perform the following procedure to replace the lead-acid low voltage battery. Wear appropriate personal protection equipment (such as safety glasses, leather gloves when handling the lead-acid battery, etc.).
Removal:
- Prepare the vehicle to remove the low voltage lead-acid battery:
- Ensure the vehicle is in Park.
- Lower all windows.
- Open the front trunk.
- Leave a door propped open so you can get back into the vehicle if needed.
