Introduction

Owning a Tesla in Australia means embracing cutting-edge technology and sustainable transportation. But it also means understanding a different approach to vehicle maintenance. Your Tesla vehicle does not require annual maintenance or regular fluid changes – a significant departure from traditional car ownership.

However, this doesn't mean your Tesla is maintenance-free. Regular care and attention to certain components will ensure optimal performance, extend your vehicle's lifespan, and potentially save you thousands of dollars in service costs. The good news? Many essential maintenance tasks can be safely performed in your own garage or driveway.

This comprehensive guide will walk you through everything you need to know about DIY Tesla maintenance, from simple daily checks to more involved procedures like tire rotation and brake caliper lubrication. We'll also clearly outline what you should never attempt yourself and when professional service is essential.

Understanding Tesla Maintenance: How It's Different

The Electric Advantage

Unlike gasoline cars, Tesla vehicles require no traditional oil changes, fuel system maintenance, spark plug replacements or emission checks. Even brake pad replacements are rare because regenerative braking returns energy to the battery, significantly reducing wear on the brakes.

This fundamental difference means:

• No oil to change or filters to replace

• No transmission fluid to service

• No spark plugs to swap

• No emissions testing required

• Minimal brake pad wear due to regenerative braking

What Still Needs Attention

Despite these advantages, your Tesla still has components that require regular maintenance:

• Tires and wheels

• Brake fluid and calipers

• Cabin air filters

• Windshield wipers and washer fluid

• 12V battery

• Cooling systems (though not user-serviceable)

• Software updates

Essential DIY Maintenance Tasks

1. Daily and Monthly Checks

These simple inspections help catch issues early and maintain optimal performance:

Daily Checks (When Practical):

• Tire Condition and Pressure: Check the condition and pressure of each tire. Look for abnormal wear patterns, cuts, or bulges

• Exterior Lights: Verify all lights, horn, turn signals work properly

• Dashboard Alerts: Check for any unexpected indicator lights or vehicle alerts on the touchscreen

• Unusual Deposits: 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)

Monthly Maintenance:

• Brake Function: Because Model 3 uses 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

• Autopilot Cameras: Tesla recommends that drivers clean their Autopilot cameras on a weekly basis during wet weather and monthly during the dry season

• Software Updates: Check for and install any available updates

2. Tire Maintenance and Rotation

Proper tire care is crucial for safety, efficiency, and longevity.

Tire Pressure Management

• Always remember to check the pressure of your tires—including the spare, if you have one—using a digital tire pressure tester

• Check pressures when tires are cold (stationary for over three hours)

• Refer to the Tire and Loading Information Label on your driver's door jamb

• Tesla recommends 42 PSI for most configurations, but verify for your specific model

DIY Tire Rotation

Tesla recommends rotating your tires every 6,250 miles or if the difference of tread depth between two of your tires is 2/32 inches or greater, whichever comes first.

Rotation Pattern:

• Same-size tires: Move front tires to opposite side in rear. Move rear tires only to front

• Different-size front/rear: Only rotate side-to-side on the same axle

• Directional tires: Move front to rear on same side only

Important: After rotation, reset the TPMS through the touchscreen:

1. Enter Service Mode

2. Navigate to Chassis > Alignment & Tires > Reset Learned Tire Values

3. Run the routine and allow it to complete

Consider investing in quality floor mats to protect your interior while performing maintenance.

3. Cabin Air Filter Replacement

The cabin air filter removes allergens, dust, and other pollutants from the air within the cabin. The cabin air filter should be replaced every two years, or as needed.

DIY Replacement Steps:

1. Access the filter location (usually behind the glovebox)

2. Remove the old filter, noting its orientation

3. Install the new filter in the same direction

4. Ensure proper fitment before reassembly

4. Windshield Wiper and Washer Fluid

These are among the most straightforward maintenance items.

Wiper Blade Replacement:

• Check for streaking or poor visibility

• Lift wiper arms away from windshield

• Release the old blade and install the new one

• Tesla provides specific instructions in their DIY guides

Washer Fluid Top-Up:

• Simply open the frunk

• Locate the washer fluid reservoir

• Fill with appropriate washer fluid for your climate

Protect your vehicle's exterior with a quality car cover when not in use.

5. 12V Battery Replacement

The 12V battery typically lasts 3-4 years and can be replaced at home with proper precautions.

Safety First:

• Wear appropriate personal protection equipment (such as safety glasses, leather gloves when handling the lead-acid battery)

• Ensure the vehicle is in Park

• Lower all windows and leave a door open

Basic Procedure:

1. Power off the vehicle via touchscreen (Controls > Safety > Power Off)

2. Disconnect the negative terminal first
