2021 Subaru Forester: True Cost of Ownership (5-Year Breakdown)
The 2021 Subaru Forester is a compact SUV built for drivers who want all-weather confidence, strong safety ratings, and practical utility without a luxury price tag. With standard symmetrical all-wheel drive and a spacious cabin, it appeals to young families, outdoor enthusiasts, and commuters in snow-prone regions. At a used price of around $23,000, it sits in a competitive sweet spot for the segment.
Monthly cost breakdown
The 2021 Forester retains value reasonably well for a compact SUV, typically losing around 37-42% of its value over five years — slightly better than average for the segment thanks to Subaru's strong brand loyalty and AWD demand in northern states.
Pros
- Standard AWD is included at no extra cost, a significant value-add versus competitors that charge $1,500-$2,000 for it
- Strong IIHS Top Safety Pick+ rating reduces insurance risk and long-term liability
- Relatively affordable routine maintenance — oil changes, filters, and brake service are competitively priced at independent shops
- Above-average resale value cushions depreciation compared to segment rivals like the Ford Escape or Chevrolet Equinox
Cons
- Fuel economy of roughly 28 MPG combined is decent but trails non-AWD competitors and hybrid alternatives, keeping fuel costs elevated
- CVT repair costs can exceed $3,500-$4,500 out of warranty, representing a notable financial risk after 100k miles
- Required premium 87 octane is fine, but oil consumption means more frequent top-offs between 5,000-mile oil change intervals
- Insurance costs trend slightly higher than the class average due to the high rate of windshield claims on this model
Common problems to watch for
- Oil consumption issues on the 2.5L FB25 engine are a known concern — check oil level regularly between changes
- EyeSight driver-assist system can be overly sensitive and occasionally triggers false braking alerts
- CVT transmission can feel sluggish under hard acceleration and has shown long-term reliability questions beyond 100k miles
- Windshield stress cracks are disproportionately reported due to the steep rake angle and EyeSight camera placement
- Infotainment system (StarLink) receives poor usability reviews and can lag or freeze on older software versions
The verdict
The 2021 Subaru Forester is a sensible, cost-competitive ownership choice — especially if purchased in the $22,000-$24,000 range where depreciation has already done most of its early-year damage. Watch for oil consumption and budget for a possible CVT service beyond 100k miles, but day-to-day running costs are manageable. For buyers who need AWD reliability and strong safety scores, the Forester delivers genuine long-term value.
Best for: The 2021 Forester is ideal for a buyer in a four-season climate who drives mixed city and highway miles, values safety technology, and wants a practical all-wheel-drive SUV without crossing into luxury pricing territory.

Does the 2021 Subaru Forester have oil consumption problems?
Yes, the FB25 2.5L engine in the 2021 Forester has a documented tendency to consume oil between changes. Subaru considers up to one quart per 1,200 miles acceptable, so check your dipstick monthly and keep a quart in the trunk.

How long does a 2021 Subaru Forester CVT transmission last?
With proper fluid changes every 30,000-60,000 miles, the Lineartronic CVT can last well past 150,000 miles, but neglected units have shown failures in the 80,000-100,000 mile range — a $3,500+ repair.
Is the 2021 Subaru Forester a good value compared to a 2021 Honda CR-V?
The Forester undercuts the CR-V slightly on purchase price and includes AWD as standard, but the CR-V's 1.5T turbocharged engine offers better fuel economy and a more refined CVT, making it a close call depending on your priorities.
What scheduled maintenance does a 2021 Subaru Forester need in the first 5 years?
Key services include oil changes every 6,000 miles (~$60-80 each), a cabin and engine air filter replacement around 30,000 miles, brake fluid flush at 30,000 miles, and a spark plug replacement near 60,000 miles — totaling roughly $1,200-$1,500 in scheduled maintenance over five years under normal driving conditions.
