2018 Subaru Crosstrek: True Cost of Ownership (5-Year Breakdown)
The 2018 Subaru Crosstrek is a compact crossover built on the Impreza platform, offering standard all-wheel drive, 8.7 inches of ground clearance, and a reputation for reliability that appeals to outdoor enthusiasts and daily commuters alike. At around $16,500 on the used market, it hits a sweet spot for buyers who want SUV versatility without full SUV running costs. It's especially popular in snow-belt states and among buyers who want a capable, fuel-efficient vehicle that holds its value unusually well.
Monthly cost breakdown
The 2018 Crosstrek retains value exceptionally well for its segment — Subaru crossovers consistently rank among the top 20% for resale value, and a 2018 model purchased at $16,500 is projected to be worth roughly $9,500–$10,500 after five more years of ownership. Much of the steepest depreciation has already been absorbed by prior owners, making this a relatively stable used buy.
Pros
- Depreciation curve has largely flattened at this price point, meaning you lose far less value per year than buying new
- Standard AWD is included at no extra cost, unlike many competitors where AWD adds $1,500–$2,000
- Fuel economy of 27–29 MPG combined is competitive for an AWD crossover, keeping fuel costs reasonable at typical US gas prices
- Subaru's parts ecosystem is well-supported and independent mechanics can service it easily, keeping repair costs below average for the segment
Cons
- The 2.0L naturally aspirated engine produces only 152 hp, which feels underpowered on highway merges and requires more throttle — slightly increasing real-world fuel consumption
- Insurance costs are slightly above segment average due to the EyeSight system making repairs more expensive after even minor front-end incidents
- CVT maintenance and potential replacement (estimated $3,500–$5,000 out of warranty) is a meaningful tail risk on higher-mileage examples
- Cargo and interior space is tighter than true compact SUVs like a RAV4 or CR-V, limiting utility relative to running costs
Common problems to watch for
- CVT transmission can feel sluggish and has reported shuddering or hesitation issues, particularly in early 2018 models — verify service history and test drive carefully
- Oil consumption between changes is a known concern on the 2.0L FB20 engine; check for blue exhaust smoke and ask for oil consumption records
- Windshield stress cracks are disproportionately common on Subaru models from this era due to the steeply raked angle — budget for possible replacement, which can run $400–$800 with EyeSight recalibration
- Head gasket issues, while more prevalent on older Subaru engines, should be watched on higher-mileage examples; verify coolant condition and look for milky oil
- EyeSight driver-assist camera calibration can be expensive after windshield replacement or front-end repairs — expect $150–$300 for recalibration alone
The verdict
From a pure cost-of-ownership standpoint, the 2018 Crosstrek is a smart used buy — the worst depreciation is behind it, fuel and maintenance costs are predictable, and Subaru reliability keeps unplanned repair bills manageable for most owners. The main financial risk is CVT longevity on higher-mileage units, so prioritize examples under 70,000 miles with documented service history. If you can verify a clean maintenance record and pass a pre-purchase inspection, this vehicle offers genuine value at $16,500.
Best for: The 2018 Crosstrek is ideal for a budget-conscious buyer in a cold or mountainous region who drives 10,000–15,000 miles per year and wants a reliable, all-weather vehicle with low long-term ownership risk.

How it compares
Frequently asked questions
How reliable is the 2018 Subaru Crosstrek long-term?
The 2018 Crosstrek scores above average for reliability in its class, with most owners reporting minimal issues under 100,000 miles when oil changes are performed on schedule. The main long-term concerns are CVT durability and oil consumption on the FB20 engine.
What is the fuel economy of the 2018 Crosstrek in real-world driving?
EPA ratings are 27 MPG city and 33 MPG highway, with real-world averages typically coming in around 28–30 MPG combined depending on driving style. At $3.50/gallon and 12,000 miles per year, expect to spend roughly $1,400–$1,500 annually on fuel.
Is the 2018 Crosstrek CVT a problem?
The CVT is functional but has known reports of shuddering or sluggish response, especially in early production 2018 units. It's not a universal failure, but a thorough test drive and pre-purchase inspection should specifically assess CVT behavior.
How much does it cost to insure a 2018 Subaru Crosstrek?
National average full-coverage insurance for a 2018 Crosstrek runs approximately $1,200–$1,500 per year, or roughly $100–$125 per month, depending on your location, driving record, and coverage level. The EyeSight system can push repair costs — and therefore premiums — slightly higher.
Does the 2018 Crosstrek have head gasket problems like older Subarus?
The FB20 engine used in the 2018 Crosstrek is a newer design and does not have the same head gasket failure rate as the older EJ series engines. However, it's still worth checking coolant condition and looking for signs of overheating on any used example.
What should I look for when buying a used 2018 Crosstrek?
Prioritize examples under 70,000 miles with documented oil change history, check for signs of oil consumption, test the CVT for shuddering, inspect the windshield for cracks, and get a pre-purchase inspection from a Subaru-familiar mechanic. Avoid any example with a history of front-end collisions due to EyeSight recalibration costs.
