2018 Subaru Forester: True Cost of Ownership (5-Year Breakdown)
The 2018 Subaru Forester is a compact SUV that blends all-wheel-drive capability with practical cargo space and strong safety ratings, making it a favorite among families, outdoor enthusiasts, and commuters in snowy or rainy climates. At around $19,000 on the used market, it sits in a sweet spot for buyers who want reliability and versatility without a new-car price tag. This guide breaks down the true cost of owning one over five years so you know exactly what you're signing up for.
Monthly cost breakdown
The 2018 Forester retains value reasonably well for a compact SUV, having already shed the steepest portion of its depreciation curve — expect it to lose roughly $4,500–$5,500 over five more years of ownership from a $19,000 purchase price. Subaru's strong brand loyalty and AWD demand help prop up resale values compared to two-wheel-drive competitors.
Pros
- Already past the steepest depreciation drop, so your out-of-pocket loss per month is relatively modest at roughly $195
- Standard symmetrical AWD adds genuine all-weather capability at no extra ownership cost versus competitors that charge for it
- Maintenance costs are below the compact SUV average — routine services average $60–$100 at independent shops familiar with Subarus
- Strong parts availability and a large DIY community keep repair costs competitive
Cons
- Fuel economy of roughly 26 MPG combined (2.5L non-turbo) lags behind some competing crossovers, adding up over 60,000 miles
- Insurance runs slightly above average for the segment due to the cost of EyeSight sensor recalibration and AWD repair complexity
- CVT fluid service is often skipped by previous owners, creating a hidden risk expense of $2,000–$5,000 if the transmission needs work
- Oil consumption on higher-mileage examples can quietly add $100–$200 per year in unplanned top-off costs
Common problems to watch for
- Oil consumption issues on the 2.5L FB25 engine — check dipstick regularly and budget for top-offs between changes
- CVT transmission can be costly to repair or replace if neglected; always verify fluid service history before buying
- Head gasket seepage is a known long-term Subaru concern, though the FB-series engine is less prone than older EJ engines — still worth a pre-purchase inspection
- Windshield stress cracks are disproportionately common on Foresters due to body flex; EyeSight camera calibration adds cost to replacements ($400–$600 total)
- Rear differential and AWD components can wear prematurely if tire sizes are mismatched or rotation schedules are skipped
The verdict
At $19,000 with its depreciation largely absorbed, the 2018 Forester is a genuinely smart cost-of-ownership choice — provided you get a pre-purchase inspection and confirm CVT fluid and oil consumption history. Its all-in monthly cost of roughly $621 is fair for a capable, safe, all-wheel-drive SUV in this class. Buyers who maintain it diligently can expect reliable, low-drama ownership through 150,000+ miles.
Best for: The 2018 Forester is ideal for a budget-conscious buyer who regularly drives in snow or rain, needs practical family or cargo hauling space, and plans to keep the vehicle long enough to amortize the AWD premium across many years.

Frequently asked questions
How many miles is too many for a used 2018 Subaru Forester?
A well-maintained 2018 Forester can reach 150,000–200,000 miles. Under 80,000 miles is a comfortable sweet spot, but up to 100,000 is acceptable if service records confirm CVT fluid changes and no oil consumption complaints.
Does the 2018 Subaru Forester have head gasket problems?
The newer FB25 2.5L engine used in the 2018 Forester is significantly improved over the older EJ series and is not widely known for head gasket failures. It's still worth a coolant condition check during a pre-purchase inspection, but it's not a primary concern at this age.
What is the average insurance cost for a 2018 Subaru Forester?
Most drivers pay between $1,500–$1,800 per year (roughly $125–$150/month) for full coverage on a 2018 Forester, though rates vary by location, driving history, and coverage limits.
Is the CVT transmission in the 2018 Forester reliable?
The Lineartronic CVT is generally reliable when properly serviced — Subaru recommends fluid changes every 25,000–30,000 miles under severe conditions. Skipping this service is the leading cause of premature CVT failure, so always verify the history before buying.
How much does it cost to replace the windshield on a 2018 Subaru Forester with EyeSight?
Expect $400–$650 total for a windshield replacement on an EyeSight-equipped Forester, since the dual cameras mounted to the glass require recalibration after installation — roughly $150–$200 more than a non-EyeSight model.
What is the resale value of a 2018 Subaru Forester after 5 more years?
Purchased at $19,000 today, a 2018 Forester in good condition with average mileage could realistically be worth $13,000–$14,500 in five years, reflecting Subaru's above-average resale retention driven by AWD demand and brand loyalty.
