Subaru Solterra Maintenance: A Complete Guide

Maintaining the electric powertrain of your Subaru Solterra is essential for ensuring optimal performance, longevity, and safety. As Subaru’s first all-electric vehicle, the Solterra combines innovative technology with Subaru’s renowned reliability. To keep your Solterra running smoothly, it’s important to follow a comprehensive maintenance plan that addresses the unique aspects of its electric powertrain. In this guide, we’ll explore key maintenance practices, the recommended service schedule, and the benefits of utilizing the Hello Subaru Temecula Service Center, part of the Hello Auto Group, for your Solterra’s care.

Understanding the Subaru Solterra’s Electric Powertrain

The Subaru Solterra features an advanced electric powertrain comprising a high-capacity lithium-ion battery pack, electric motors, and associated electronic components. Unlike traditional internal combustion engines, electric vehicles (EVs) have fewer moving parts, which can lead to reduced maintenance needs. However, specific components require regular attention to ensure optimal performance.

Battery Maintenance

The heart of the Solterra’s powertrain is its lithium-ion battery pack. Proper battery maintenance is crucial to maximizing range and longevity.

• Regular Inspections: Periodic checks of the battery system are essential. Subaru recommends inspecting the traction battery coolant at 18 months or 15,000 miles, and then every 30,000 miles thereafter.
• Coolant Replacement: The traction battery coolant should be replaced at 120,000 miles and every 50,000 miles to maintain optimal thermal management.
• Software Updates: Ensure that your Solterra’s battery management system is up-to-date with the latest software. This can improve efficiency and address any manufacturer-recommended updates.

Charging Practices

Proper charging habits can significantly affect the health and performance of your Solterra’s battery.

• Use Recommended Chargers: Always use Subaru-approved charging equipment. The Solterra is compatible with Level 1 (120V) and Level 2 (240V) chargers.
• Avoid Frequent Fast Charging: While DC fast charging is convenient, frequent use can accelerate battery degradation. Reserve fast charging for long trips or when necessary.
• Maintain Optimal Charge Levels: Keeping the battery charge between 20% and 80% can help prolong its lifespan. Avoid letting the battery deplete completely or remain at 100% for extended periods.

Electric Motor and Drivetrain Maintenance

The Solterra’s electric motors and drivetrain components are designed for durability but still require attention.

• Regular Inspections: Inspect the e-Transaxle fluid at 36 months or 30,000 miles and replace it at 72 months or 60,000 miles.
• Monitor for Unusual Noises: Be attentive to any unusual sounds during operation, as they may indicate issues with the electric motors or drivetrain components.

Brake System Maintenance

The Solterra utilizes regenerative braking, which reduces wear on traditional brake components. However, regular maintenance is still necessary.

• Brake Inspections: Inspect brake pads and discs every 6 months or 5,000 miles to ensure they are in good condition.
• Brake Fluid Replacement: Replace the brake fluid as the maintenance schedule recommends to maintain braking efficiency.

Tire Maintenance

Proper tire maintenance is crucial for safety and efficiency.

• Tire Rotations: Perform tire rotations every 6 months or 5,000 miles to promote even wear.
• Alignment Checks: Regularly check wheel alignment to prevent uneven tire wear and ensure optimal handling.

Subaru EV Maintenance Schedule

Adhering to the manufacturer’s maintenance schedule is vital for the longevity of your Solterra. The recommended maintenance intervals include:

• 6 Months/5,000 Miles: Inspect brake pads and discs, steering linkage, suspension components, and perform tire rotation.
• 12 Months/10,000 Miles: Repeat the 6-month service checks.
• 18 Months/15,000 Miles: Inspect heater coolant, traction battery coolant, brake lines and hoses, and steering gearbox.
• 24 Months/20,000 Miles: Repeat the 6-month service checks.
• 36 Months/30,000 Miles: Inspect e-Transaxle fluid and replace the air conditioning filter.
• 72 Months/60,000 Miles: Replace e-Transaxle fluid and repeat previous inspections.
