Quick Reference
| Mileage | Service | Notes |
|---|---|---|
| 5,000 | Oil & Filter, Tire Rotation | First service is crucial for a new engine. |
| 10,000 | Oil & Filter, Tire Rotation | |
| 15,000 | Oil & Filter, Tire Rotation | |
| 30,000 | Oil & Filter, Tire Rotation, Cabin & Engine Air Filter, Brake Fluid Flush | First major service. Brake fluid is hygroscopic and absorbs water over time. |
| 60,000 | Oil & Filter, Tire Rotation, Cabin & Engine Air Filter, Spark Plugs, Brake Fluid Flush, Differential & Transfer Case Service | Spark plugs are replaced at this interval to maintain optimal fuel economy and performance. |
| 100,000 | Oil & Filter, Tire Rotation, Cabin & Engine Air Filter, PCV Valve, Accessory Belt | PCV valve replacement is critical for engine longevity. Accessory belt drives the alternator, water pump, and A/C compressor. |
| 150,000 | Oil & Filter, Tire Rotation, Cabin & Engine Air Filter, Coolant Flush, Transmission Fluid Service | First coolant flush. Transmission fluid service is recommended to ensure smooth shifting and a long transmission life. |
Severe-duty schedule
The severe-duty schedule is for owners who use their Forester for towing, live in dusty or cold climates, or frequently make short trips. Under these conditions, the oil and filter should be changed every 3,000 miles. The cabin and engine air filters should be inspected and replaced more frequently, and the differential and transfer case fluid should be changed every 30,000 miles. The transmission fluid should be changed every 30,000 miles as well.
Known issues by mileage
This generation of Forester is new, so there is limited data on known issues. However, based on previous generations, here are some things to look out for:
- 30,000 miles: Premature brake wear. Some owners have reported needing to replace their front brake pads and rotors sooner than expected.
- 60,000 miles: Wheel bearing failure. This is a common issue on Subarus, and it's a good idea to have them inspected at this interval.
- 100,000 miles: Head gasket failure. While Subaru has made improvements to their head gaskets over the years, it's still a good idea to have them inspected at this interval.
Estimated cost per service
- 5,000 miles: $50 - $100
- 10,000 miles: $50 - $100
- 15,000 miles: $50 - $100
- 30,000 miles: $200 - $400
- 60,000 miles: $400 - $800
- 100,000 miles: $200 - $400
- 150,000 miles: $600 - $1,200
