Is the 2018 Subaru Outback reliable?

Owners rate it 4.67/5, a strong signal of long-term satisfaction.

The owner feedback points to a vehicle people tend to trust and keep, with repeated praise for its smooth ride, strong safety features, and overall practicality. The expert evaluation also emphasizes the Outback’s durable, go-anywhere character and its ability to handle rough weather and light off-road use with confidence.

The 2018 model’s dependability is reinforced by its all-wheel-drive setup and the sense that it’s built for long-term utility rather than short-term novelty. For used buyers, the main ownership risk is making sure the specific vehicle has been maintained well, since a practical all-weather car can still become expensive if neglected.

What should I look for when buying a used 2018 Subaru Outback?

At 69.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a thorough pre-purchase inspection, especially if you’re considering a higher-mileage example or one with visible wear. Focus on condition, maintenance records, and whether the car’s safety and convenience equipment works as expected.

Key things to evaluate:

• Trim level: The base model comes with standard all-wheel drive and a CVT, while the 2.5i Premium, 2.5i Limited, 2.5i Touring, 3.6R Limited, and 3.6R Touring add equipment and refinement. The base trim is the one most likely to leave you wanting more, especially if you want the available driver-assistance package.
• Powertrain: The 2.5-liter 4-cylinder makes 175 horsepower and 174 lb-ft of torque, while the 3.6-liter 6-cylinder makes 256 horsepower and 247 lb-ft of torque. The 6-cylinder is the better choice if you want stronger acceleration and more relaxed passing power.
• Safety package: EyeSight is the named driver-assistance suite, and it includes adaptive cruise control with stop-and-go capability plus lane-keeping assist. It is available on every Outback except the base trim.
• Infotainment: The larger 8-inch Starlink display gets faster start-up and response times, better voice recognition, new on-screen apps, and over-the-air software updates. The system is described as more smartphone-like and more natural to use.
• Fuel efficiency: The 2.5i is rated at 28 mpg in combined driving, while the 3.6R is expected to get 22 mpg. Real-world testing showed 21.9 mpg for the 2.5i.

Which 2018 Subaru Outback trim should I buy?

The 2018 Subaru Outback is offered in 6 trim levels: base model, 2.5i Premium, 2.5i Limited, 2.5i Touring, 3.6R Limited, 3.6R Touring.

Here's the short version:

• base model: This is the least expensive way into the Outback, but it’s also the one that skips EyeSight. If you want the lowest entry price and can live without the available driver-assistance suite, this is the most basic choice.
• 2.5i Premium: This is the best-value trim because it adds more equipment while still keeping the Outback relatively affordable. It’s the trim the cost-effectiveness guidance points to if you want the strongest balance of price and features.
• 2.5i Limited: This trim adds more upscale content and is a better fit if you want a more polished cabin and more comfort-oriented equipment.
• 2.5i Touring: This is the most feature-rich 2.5i trim, so it makes sense if you want the nicer appointments without moving to the 6-cylinder lineup.
• 3.6R Limited: This is the entry point for the 6-cylinder engine, and it’s the right pick if you want stronger power. It’s the minimum trim you need if the 6-cylinder matters to you.
• 3.6R Touring: This is the top-end choice if you want the strongest engine plus the most upscale trim content.

EyeSight is available on every Outback except the base trim, so that’s an important safety-package note to keep in mind.

Is now a good time to buy a used 2018 Subaru Outback?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 33.9% of listings are priced as good or great deals.
• Inventory: There are 2,431 listings available.
• Price trend: Prices have softened 6.92% compared with last year.
• Clean inventory: 69.3% of listings are accident-free.

If you find a listing below $15,931, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Subaru Outback's resale value?

The current average of $15,938 sits slightly below last year's $17,123.

That decline suggests the market has become more favorable for buyers, but it also means sellers may need to price competitively to move a used Outback. If you’re planning to sell later, the current trend shows that values have softened, so holding out for a premium may be harder than it was a year ago.

Even so, the Outback’s broad appeal as a practical, safe, all-weather vehicle should help support demand. Models with strong equipment, clean history, and good condition are likely to remain easier to sell than less desirable examples.

Vehicles with strong owner satisfaction ratings, like this model year's 4.67/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 Subaru Outback safe?

The 2018 Subaru Outback earns five-star ratings across the board from NHTSA except for rollover resistance, which rates four stars. It also earns a Top Safety Pick+ rating from IIHS.

It earns a 10/10 safety score from our experts.

EyeSight is the named driver-assistance suite, and it’s available on every Outback except the base trim. Its standard functions include adaptive cruise control with stop-and-go capability and lane-keeping assist, and the car also offers reverse automatic braking.

The main caveat is the rollover result, which is lower than the other federal crash ratings because of the Outback’s raised suspension.

Should I buy a 2018 Subaru Outback or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 33.9% of listings are priced as good or great deals.
• At 69.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.92% compared with last year.
• Owners rate it 4.67/5 — a strong satisfaction signal.
• The 2018 model brings updated styling, a quieter cabin, and improved Starlink infotainment with faster response and over-the-air updates.

The bottom line: If you want a used Outback with strong safety, solid owner satisfaction, and a softer price than last year, the 2018 is a sensible choice. If you’re especially price-sensitive, you may want to compare it with nearby years, but the 2018 stands out for its mix of value, safety, and everyday usefulness.
