2025 Subaru Solterra Maintenance Schedule

The Subaru Solterra marks an exciting milestone as Subaru’s first all-electric vehicle (EV). Although proper maintenance is key to ensuring optimal efficiency, EVs, such as the Solterra, have unique needs compared to traditional gas-powered cars. In this article, your team at Huffines Subaru Corinth discusses the Subaru Solterra’s maintenance schedule and explores how to keep your EV in top condition.

Detailed Subaru Solterra Maintenance Schedule

Subaru has designed a comprehensive maintenance schedule for the Solterra to keep it in optimal condition.

Every 6 Months or 5,000 Miles

This basic check-up includes the following:

• Brake pad and disc inspection
• Steering linkage check
• Suspension and drive shaft examination
• Tire rotation
• Chassis bolt tightening
• Battery health check — both the 12V and main traction battery
• Fluid level checks

This helps to identify any potential issues early, ensuring your Solterra’s safety and efficiency on the road.

Annual Service — 12 Months or 10,000 Miles

In addition to the six-month checks, your annual service will include the following:

• Cabin air filter inspection
• Brake fluid inspection
• Coolant level checks
• Wiper blade inspection and replacement, if needed

This more comprehensive service helps to maintain your Solterra’s comfort and safety systems.

18 Months or 15,000 Miles

At this milestone, your Solterra will receive additional attention to its cooling and braking systems, including the following:

• Heater and traction battery coolant inspection
• Brake line and hose examination
• Steering gear box inspection

These checks are crucial for maintaining your EV’s performance and safety, especially as it ages.

24 Months or 20,000 Miles

This service includes all previous checks, as well as the following:

• Brake fluid replacement
• Comprehensive suspension system check

Regular brake fluid replacement is essential for maintaining your Solterra’s braking performance, even though EVs typically experience less brake wear due to regenerative braking.

36 Months or 30,000 Miles

At the three-year mark, your Solterra will need the following:

• Air conditioning filter replacement
• Comprehensive electrical system check

These checks help ensure that your Solterra’s systems continue to function optimally.

48 Months or 40,000 Miles

This service includes another brake fluid replacement and a thorough coolant system inspection. Regular coolant checks are vital for EVs such as the Solterra, as proper cooling helps maintain battery health and performance.

60 Months or 50,000 Miles

At five years, your Solterra will undergo the following checks:

• Comprehensive battery system inspection
• Thorough suspension system check

These in-depth inspections help ensure your Solterra continues to perform well as it ages.

72 Months or 60,000 Miles

This major service includes the following:

• e-Transaxle fluid replacement
• Air conditioning filter replacement
• Comprehensive vehicle systems check

This service is crucial for maintaining your Solterra’s long-term health and performance.

Long-Term Maintenance — Beyond 72 Months

To ensure the long-term health of your Solterra, it will need the following:

• Heater and traction battery coolant replacement at 120,000 miles and every 50,000 miles after that
• Air conditioning refrigerant refill every 96,000 miles

These long-term maintenance tasks help ensure that your Solterra continues to perform well for many years to come.

The Importance of Regular Maintenance for Your Solterra

Adhering to a maintenance schedule significantly impacts your car’s safety and performance, as well as your wallet.

Safety First

Regular maintenance of your Solterra’s brake system, tires, and suspension is crucial for safety. Even though EVs, such as the Solterra, use regenerative braking, which reduces wear on brake pads, regular inspections are still important. Proper tire rotations and alignments ensure even wear and optimal regenerative braking performance.

Optimal Performance

Regular maintenance of your Solterra, especially its battery system, ensures its optimal performance. Proper care can help maintain battery performance and longevity. The coolant system, which manages battery temperature, also needs regular attention to ensure maximum range and efficiency.

Financial Benefits

While maintenance does come at a cost, it can save you money in the long run. Regular check-ups can identify small issues before they escalate into expensive problems. A well-maintained Solterra will likely have a higher resale value. A properly maintained EV is also more energy-efficient, potentially saving you money on charging costs.

Maintenance and Your Warranty

Adhering to your vehicle’s maintenance schedule is also important for your warranty. Although Subaru offers a comprehensive warranty for the Solterra, you must follow the recommended maintenance schedule. Make sure to keep all your service records since you’ll need them if you ever make a warranty claim.

Tips for Keeping Your Subaru Solterra Running Smoothly Between Service Visits

While regular professional maintenance is crucial, the following will help you keep your Solterra in optimal condition between services:

• Regularly inspect your car’s exterior and undercarriage for any obvious issues.
• Keep your Solterra clean — proper cleaning helps preserve the paint and can reveal potential problems.
• Check tire pressure regularly and adjust as needed.
• Top up windshield washer fluid as needed.

Try to adhere to the following best practices when charging your vehicle:

• For daily use, try to keep your battery charge between 20% and 80%.
• When storing your Solterra for a long period, aim for a 50% charge.
• Use fast charging sparingly — it’s convenient, but frequent use can impact battery longevity.

Your driving habits can also impact your Solterra’s longevity. Try to use regenerative braking efficiently, avoid extreme acceleration and braking, and be mindful of battery temperature management, especially in very hot or cold conditions.

When To Seek Professional Service Ahead of Schedule

While the maintenance schedule provides a good guide, sometimes your Solterra may need attention sooner. Watch out for warning signs such as unusual noises, handling issues, or changes in battery performance. If you notice anything out of the ordinary, it’s best to have it checked out by a professional.

Software updates are another important aspect of EV maintenance. While many updates can be done over the air, some may require a visit to the dealership. Stay informed about available updates for your Solterra.
