The 2021 Crosstrek at 5 Years: Cheap to Own, With One Catch

At $545 a month all-in, the 2021 Subaru Crosstrek is one of the cheaper compact crossovers you can own right now. That number, from our five-year ownership calculator, covers depreciation, fuel, repairs, maintenance, insurance, and registration on a typical used example doing 12,000 miles a year. The question is not whether that number is low. It is. The question is whether the used market is pricing these cars high enough to eat that advantage before you even get the keys.

Right now, a clean 2021 Crosstrek with 50,000 to 65,000 miles is listing in the $21,000 to $25,000 range depending on trim, according to Kelley Blue Book and Edmunds. That is still expensive for a five-year-old economy crossover with a 152-horsepower engine. If you can find one at $20,000 or below, buy it. If the dealer is asking $24,000, walk unless it is the Sport or Limited trim with documented service history. The base and Premium trims are not worth $24,000 in 2025.

The One Engine Decision That Changes Everything

The 2021 Crosstrek came with two engines: the 2.0-liter flat-four in the base, Premium, and Sport trims, and the 2.5-liter flat-four in the Limited. Buy the 2.5 if you can afford the premium. Not because the 2.0 is unreliable, but because it is genuinely underpowered, and Subaru's 2.0-liter boxer has a well-documented oil consumption problem.

Some 2.0 owners report needing a quart of oil every 1,500 to 2,000 miles. Subaru considers consumption below one quart per 1,200 miles acceptable. That is not a typo. The 2.5-liter in the Limited does not have this reputation. If you are buying a 2.0-liter Crosstrek, you need to confirm the specific car's oil consumption history before purchasing. More on how to check that below.

For recalls, check the NHTSA recall database for this model year. The 2021 Crosstrek had recalls related to the fuel injector and a separate one involving the EyeSight driver assistance cameras. Both are dealer-corrected under recall at no cost, but verify the VIN to confirm the work was done on the specific car you are considering.

What the $3,332 in Repairs Actually Looks Like

Our five-year repair estimate of $3,332 works out to roughly $667 a year. That is not bad. RepairPal rates the Crosstrek above average for reliability and puts annual repair costs around $516, which is consistent with a low-mileage used example.

But mileage matters a lot here. Here is a realistic breakdown by mileage band:

Under 50,000 miles: You are mostly looking at maintenance, not repairs. Budget $400 to $600 per year for repairs. The main surprise at this stage is oil consumption on the 2.0, which costs nothing to fix if you catch it early but can damage the engine if ignored.

50,000 to 100,000 miles: This is where the Crosstrek starts showing its actual failure modes. Expect wheel bearing replacements ($300 to $500 per corner), potential CVT fluid service if the previous owner skipped it ($150 to $250), and the beginning of suspension wear. Budget $800 to $1,200 per year for repairs in this range. Some owners also report issues with the EyeSight system giving false alerts or disabling itself, which can involve camera realignment or sensor replacement at $200 to $600.

Over 100,000 miles: The CVT transmission is the biggest unknown. Subaru's CVT is not the disaster it is on some other brands, but neglected fluid changes accelerate wear. A CVT rebuild or replacement on a Crosstrek runs $3,500 to $5,000. If you are buying a high-mileage example and there is no record of CVT fluid changes, price that risk into your offer. Also budget for timing chain tensioner noise on the 2.0, which starts appearing around 100k on high-consumption engines. Annual repair budget at this stage: $1,200 to $2,000.

What You Will Actually Spend on Fuel

The EPA rates the 2021 Crosstrek at 27 mpg city and 33 mpg highway for the base 2.0-liter, with a combined rating of 29 mpg. The 2.5-liter Limited drops to 25 combined. You can verify those numbers at fueleconomy.gov.

At 12,000 miles per year and $3.50 per gallon, the 2.0-liter costs about $1,448 in fuel annually. The 2.5-liter costs about $1,680. Our five-year fuel estimate of $9,144 lines up with the 2.0-liter figure, which is fair for a typical buyer. These are not impressive numbers. A Toyota Corolla Cross or a Honda HR-V will do better. But for a car with standard all-wheel drive, the Crosstrek's fuel cost is reasonable. You are paying a gas penalty for the AWD system that comes standard on every trim.

Note that the Crosstrek requires premium fuel only if you want it. It runs fine on regular 87 octane, which keeps that $9,144 from climbing.

Nine Things to Check Before You Buy This Specific Car

1. Oil consumption test on the 2.0-liter. Ask when the oil was last changed, add it to full if needed, then drive 1,000 miles and check the dipstick. If it is noticeably low, you have a consumer. Budget for top-offs or walk away depending on severity.

2. CVT transmission fluid condition. Pull the dipstick if accessible, or ask for service records. Dark brown or burned-smelling fluid on a car over 60,000 miles means the previous owner skipped Subaru's recommended fluid change interval. A flush at purchase is cheap. A new CVT is not.

3. Head gasket history. The older 2.5-liter Subaru engines were notorious for head gasket failures. The 2021 version of the engine is significantly revised, but check the coolant reservoir for a milky or oily residue, and look for exhaust smoke on cold starts.

4. EyeSight recall completion. Pull the VIN through the NHTSA database and confirm both the EyeSight camera recall and the fuel injector recall were completed. If not, any Subaru dealer will do it free, but confirm before you buy.

5. Rear differential fluid. All-wheel drive is standard, but the rear differential fluid is a separate service item many owners skip. Check the records. If it has never been done on a car over 60,000 miles, budget $150 and have it done immediately.

6. Subframe and underbody rust. These cars are popular in northern states and the Pacific Northwest, both wet climates. Get under it and look at the subframe, control arms, and brake lines. Surface rust is normal. Scaling or flaking rust on structural components is a problem.

7. Wheel bearing noise. At highway speeds, listen for a low hum that changes pitch when you change lanes. Crosstrek wheel bearings start wearing between 60,000 and 90,000 miles. Not a dealbreaker, but price it in.

8. Infotainment touchscreen response. The Starlink system in this generation has a reputation for sluggish response and occasional freezing. It is annoying rather than dangerous, but there is no cheap fix. Test it thoroughly before buying.

9. Brake pad and rotor condition. Subaru Crosstreks are frequently used for light trail and mountain driving, which accelerates brake wear. Check pad thickness and look for grooved or scored rotors. A full brake job is $400 to $700 if it is needed soon.

The $9,240 Depreciation Number and What It Tells You

Our five-year depreciation estimate is $9,240, which means this car loses roughly $1,848 per year in value from the point you buy it. That is actually decent for a crossover in this segment. The Crosstrek holds value better than many competitors because demand has stayed strong and Subaru's AWD reputation pulls buyers in.

The flip side is that high residual value means you pay more upfront. You are not getting a bargain on the purchase price just because the car is five years old. The market knows the Crosstrek holds value, and dealers price accordingly. You get the benefit on the back end when you sell, but you pay for it now.

Two Other Crossovers Worth a Look at This Price

2021 Mazda CX-30: Similar pricing, more refined interior, and Mazda's reliability record is competitive with Subaru's, making it a genuine alternative if you do not need AWD in truly difficult conditions.

2021 Honda HR-V: Often available $2,000 to $3,000 cheaper for comparable mileage, with better fuel economy and a simpler drivetrain that carries lower long-term repair risk on high-mileage examples.

Where This Car Makes Sense, and Where It Does Not

The 2021 Crosstrek is a smart buy at $20,000 or under, with under 70,000 miles, on a car with documented service history and confirmed recall completion. At that price and mileage, the $32,681 five-year total gives you reliable, all-wheel-drive transportation for $545 a month. Above $22,000, you are overpaying for what you get unless it is the 2.5-liter Limited trim. Above 90,000 miles, the CVT risk changes the math enough that you need to either verify fluid history obsessively or negotiate a lower price to cover the possibility of a transmission service or early replacement. The 2.0-liter with no oil consumption history and a price north of $23,000 is not a deal. It is a gamble at full retail.
