2020 Subaru Outback Factory Maintenance Schedule

Quick reference

Severe-duty schedule

The 2020 Outback, like most modern vehicles, has a maintenance schedule designed for "normal" driving conditions. However, what constitutes "normal" may not reflect your driving habits. If you frequently tow, drive in dusty or dirty conditions, make short trips in cold weather, or live in a climate with extreme temperatures, you should follow a severe-duty schedule. This typically involves more frequent fluid changes and inspections.

For the 2020 Outback, this means changing the oil and filter every 3,000 miles instead of the usual 5,000. Additionally, the transmission fluid, differential fluid, and transfer case fluid should be inspected more frequently and changed as needed, often as early as 30,000 miles. The engine and cabin air filters will also require more frequent replacement, depending on the severity of the dust and debris you encounter.

Known issues by mileage

The 2020 Subaru Outback is part of a generation known for its reliability. However, like any vehicle, there are a few common issues that may arise as the miles accumulate.

• 5,000-15,000 miles: Some owners have reported infotainment system glitches, including screen freezes and unresponsive touch controls. These are often resolved with software updates from the dealership.
• 30,000-60,000 miles: Premature battery failure has been noted by some owners. If you experience slow starting or electrical issues, have the battery and charging system tested.
• 60,000-100,000 miles: Wheel bearing failure is a possibility at higher mileage. A humming or grinding noise from the wheel area that changes with speed is a common symptom.
• 100,000+ miles: While the FB25 engine's timing chain is designed to last the life of the vehicle, the chain tensioners and guides can wear, leading to a rattling noise on startup. If you hear this, have the timing chain system inspected by a qualified technician.
