Which Subaru Forester Is Most Reliable? Best Years

The Subaru Forester has built a strong reputation for practicality, all-wheel-drive capability, safety, and long-term durability. However, not every Forester model year offers the same level of reliability. Some generations have experienced expensive engine or transmission problems, while others have established themselves as dependable family SUVs.

So, which Subaru Forester is most reliable?

If we're shopping for a used Subaru Forester, the 2023 Subaru Forester with the naturally aspirated 2.5-liter Boxer engine is one of our top recommendations. The 2022 and 2024 models are also excellent candidates, offering a proven powertrain, modern safety technology, and generally favorable reliability records.

However, there are other model years worth considering, especially if we're working with a smaller budget.

In this guide, we'll compare the most reliable Subaru Forester years, identify generations with known problems, examine engine and transmission durability, and explain what to check before buying.

What Is the Most Reliable Subaru Forester Year?

The 2023 Subaru Forester is our overall pick for the most reliable used model year, although the 2024 and 2022 versions are close alternatives.

By 2023, Subaru had several years to refine the fifth-generation Forester, originally introduced for the 2019 model year in North America.

The 2023 model benefits from a mature platform, a well-established naturally aspirated Boxer engine, and improvements made throughout the generation.

It also avoids some of the better-documented problems associated with earlier fifth-generation models.

Why the 2023 Subaru Forester Stands Out

Several factors make the 2023 Forester particularly attractive:

• Proven engine: Its naturally aspirated 2.5-liter Boxer engine does not require a turbocharger.
• Established transmission: Subaru had accumulated substantial experience with its Lineartronic CVT.
• Modern safety systems: Subaru EyeSight driver-assistance technology is standard on US-market models.
• Standard all-wheel drive: Excellent traction in rain, snow, and slippery conditions.
• Practical interior: Comfortable seating, excellent visibility, and useful cargo space.
• Positive reliability evidence: Consumer Reports rates the 2023 Forester above other vehicles from the same model year for reliability.

That does not mean every 2023 Forester will be trouble-free. Previous maintenance, driving conditions, accident history, and mileage still matter.

Nevertheless, for buyers who want reliability without sacrificing modern equipment, the 2023 Forester offers a particularly appealing combination.

Most Reliable Subaru Forester Years Ranked

Based on available reliability assessments, known mechanical issues, model maturity, and ownership considerations, these are the Forester model years we would prioritize when shopping used.

This is a buying recommendation rather than a standardized statistical reliability ranking. Individual vehicle condition can change the order considerably.

1. Subaru Forester 2023: Best Overall Choice

The 2023 Forester combines relatively modern equipment with a powertrain that had already been used for several years.

In the United States, it comes with a 2.5-liter naturally aspirated four-cylinder Boxer engine producing approximately 182 horsepower, paired with a continuously variable transmission.

The engine delivers sufficient performance for daily commuting, highway driving, and family trips.

Its greatest advantage is not outright acceleration but predictable operation and a relatively straightforward powertrain compared with turbocharged alternatives.

We particularly appreciate that the 2023 model belongs to an established generation rather than the first year of an entirely new design.

Best for: Buyers seeking a modern Forester with a favorable reliability record.

2. Subaru Forester 2024: Best Late-Generation Model

The 2024 Subaru Forester is another excellent option.

It represents the final model year of the fifth-generation Forester in the US market, giving buyers a vehicle developed over several production years.

The main mechanical components are similar to those in the 2023 model.

Advantages include:

• Familiar 2.5-liter Boxer engine.
• Established Subaru Lineartronic CVT.
• Standard symmetrical all-wheel drive.
• Advanced driver-assistance features.
• Spacious and practical cabin.

Consumer Reports also rates the 2024 Forester as more reliable than other vehicles from its model year.

The main drawback is purchase price. Because the 2024 model is newer, it may cost noticeably more than a comparable 2022 or 2023 example.

If the price difference is small and both vehicles have excellent maintenance histories, the 2024 Forester is a sensible choice.

Best for: Buyers who want a relatively recent Forester without moving to the redesigned sixth generation.

3. Subaru Forester 2022: Best Value Alternative

The 2022 Forester is another model year we would strongly consider.

It received a mid-generation refresh, including styling updates and improvements to certain features.

Under the bonnet, US-market versions retained the familiar 2.5-liter Boxer engine and CVT combination.

One of its biggest advantages is that it can offer much of the functionality of a 2023 or 2024 Forester at a lower used-market price.

The 2022 model also avoids the specific 2019–2021 Forester thermo control valve warranty-extension group identified by Subaru of America.

However, we should never assume that a newer vehicle is completely immune to cooling-system problems.

Best for: Drivers who want reliability, all-wheel drive, and modern safety features without paying the highest used-car prices.

4. Subaru Forester 2021: Worth Buying With Checks

The 2021 Forester can be a reasonable alternative when priced appropriately.

By this point, the fifth-generation model was no longer brand-new, and its mechanical design was well established.

Nevertheless, the 2021 model falls within Subaru of America's thermo control valve warranty-extension program.

A failed thermo control valve can trigger engine warning lights or affect the cooling system.

Before purchasing a 2021 Forester, we recommend checking whether this component has already been replaced and whether the vehicle remains eligible for warranty coverage.

A properly maintained example with verified repair records can still be a worthwhile purchase.

5. Subaru Forester 2018: Older Budget Option

The 2018 Forester is the final model year of the fourth generation.

Although being a final-year model can be advantageous, the 2018 Forester is not automatically more dependable than newer alternatives.

Some examples experience CVT problems, wheel-bearing wear, suspension repairs, or engine oil leaks.

These concerns become more important as mileage increases.

Still, a well-maintained 2018 Forester with documented repairs may be more attractive than a neglected 2021 vehicle.

We would focus on the naturally aspirated engine for buyers prioritizing lower mechanical complexity.

Best for: Budget-conscious buyers who can obtain a thorough pre-purchase inspection.

Which Subaru Forester Generation Is Most Reliable?

Subaru has produced several Forester generations since the late 1990s.

Each generation introduced improvements in comfort, safety, engine technology, and fuel economy.

However, each also has different maintenance requirements and potential weaknesses.

First Generation: 1998–2002

The original Forester was relatively simple compared with modern SUVs.

Its compact dimensions, mechanical all-wheel-drive system, and practical body design made it popular among drivers who wanted something between a traditional wagon and an SUV.

Today, its biggest challenge is age.

Common inspection concerns include oil leaks, head gasket issues on applicable engines, corrosion, aging suspension components, and neglected timing-belt maintenance.

A carefully maintained example can still be useful, but we would not recommend this generation to someone whose primary goal is avoiding repairs.

Second Generation: 2003–2008

The second-generation Forester improved comfort and overall refinement while retaining much of the original vehicle's mechanical character.

Are Subaru Foresters Reliable in Australia?

Many examples use naturally aspirated EJ-series engines, while some markets offered turbocharged versions.

These vehicles can achieve substantial mileage when properly maintained.

However, potential head gasket repairs, cooling-system deterioration, timing-belt service, and age-related problems deserve attention.

For buyers who prefer older vehicles with conventional automatic or manual transmissions, this generation may be appealing.

Nevertheless, a 2008 Forester in 2026 is an old vehicle. Maintenance history matters far more than its original reputation.

Third Generation: 2009–2013

The third generation offered a larger cabin and more traditional SUV proportions.

Different engines were available depending on the market and model year.

Some earlier engines retained timing belts, while newer FB-series engines introduced timing chains.

Potential concerns include:

• Excessive oil consumption in certain FB-engine applications.
• Head gasket problems on some older EJ-engine variants.
• Wheel-bearing wear.
• Suspension deterioration.
• Oil leaks and cooling-system maintenance.

The 2011–2013 period requires particular attention to oil consumption.

A car with complete service records and stable oil consumption may still provide good value, but an inexpensive example with an unknown history could become costly.

Fourth Generation: 2014–2018

The fourth-generation Forester brought notable improvements in fuel economy, interior space, and safety.

However, this generation also has a mixed reliability history.

Earlier model years attracted complaints involving oil consumption, while certain CVT-equipped vehicles were included in Subaru warranty extensions.

Later examples may be preferable in some respects, but they are not free from mechanical concerns.

We would approach this generation with careful attention to the transmission, engine condition, wheel bearings, and suspension.

Fifth Generation: 2019–2024

The fifth-generation Forester is our preferred generation for most used-car buyers, particularly the 2022–2024 model years.

It benefits from improved structural rigidity, modern safety technology, comfortable seating, and a well-established naturally aspirated powertrain in the US market.

The earliest years are less appealing because of reported issues involving windshields, electrical components, and thermo control valves.

The later years offer a better balance of model maturity and ownership experience.

However, we would not treat the entire 2019–2024 generation as equally reliable.

Sixth Generation: 2025–Present

The redesigned Forester arrived for the 2025 model year in North America.

It offers improved refinement, updated styling, additional technology, and a quieter cabin.

Subaru has also introduced hybrid versions in certain markets.

The challenge is that newer vehicles have less long-term ownership history.

Consumer Reports currently characterizes the 2025 Forester's reliability as approximately average relative to other vehicles from that year and expects the 2026 model to have approximately average reliability.

This does not mean the sixth-generation Forester is unreliable.

It simply means we have less evidence about how these models will perform after many years and high mileage.

For buyers who prioritize proven long-term reliability over having the latest design, a well-maintained 2023 or 2024 Forester remains especially attractive.

Which Subaru Forester Years Should You Avoid?

Not every Forester model year deserves an outright warning.

However, some years have enough documented concerns that we would investigate them particularly carefully before purchasing.

2014–2015: Oil Consumption Concerns

Excessive engine oil consumption is one of the best-known concerns associated with certain older Forester models.

The 2014 Forester stands out in owner-complaint databases for oil consumption reports.

Potential symptoms include:

• Needing additional oil between scheduled services.
• Low-oil warning lights.
• Unusual engine noises when oil levels fall.
• Increased operating costs.
• Internal engine wear if low oil levels are ignored.

Not every 2014 or 2015 Forester suffers from excessive oil consumption, but the issue is important enough to justify checking maintenance records and monitoring the oil level.

A vehicle with documented engine repairs may deserve consideration if the work was completed correctly.

2016–2017: CVT and Suspension Issues

Certain 2016 and 2017 Forester models were included in a US-market CVT warranty-extension program.

Subaru extended applicable CVT coverage to 10 years or 100,000 miles, whichever came first, subject to the program's terms.

Importantly, the warranty extension did not mean that every affected transmission was defective.

Nevertheless, when buying one of these vehicles today, we should examine the transmission carefully.

We would look for hesitation, shuddering, unusual noises, warning lights, fluid leaks, and inconsistent acceleration.

Worn control-arm bushings and wheel bearings are additional concerns worth investigating.

2019–2020: Early Fifth-Generation Problems

The 2019 and 2020 Forester models deserve additional scrutiny because they were produced early in the fifth generation.

Reported concerns include cracked windshields, electrical problems, and thermo control valve failures.

These models can still be reliable when maintained and repaired appropriately.

However, if prices are reasonably close, we would generally prefer a 2022 or 2023 Forester with comparable mileage and service history.

Are These Subaru Forester Years Always Bad?

No.

A model year with a higher complaint rate can still contain thousands of vehicles that operate reliably.

Likewise, a model year with an excellent reputation can contain poorly maintained examples.

We should use reliability trends to create a shortlist, then evaluate individual vehicles before making a purchase.

Which Subaru Forester Engine Is Most Reliable?

Engine selection plays an important role in long-term ownership costs.

Subaru has used several Boxer engines in the Forester, including naturally aspirated petrol engines, turbocharged engines, diesel engines in selected markets, and hybrid systems.

For most buyers prioritizing reliability and relatively low mechanical complexity, the naturally aspirated 2.5-liter FB25 engine in the 2022–2024 US-market Forester is our preferred choice.

2.5-Liter Naturally Aspirated Boxer Engine

The 2.5-liter engine used in recent US-market Foresters produces around 182 horsepower.

Its horizontal cylinder arrangement is part of Subaru's traditional Boxer engine design.

Advantages include predictable power delivery, no turbocharger, and widespread familiarity among Subaru service technicians.

However, naturally aspirated does not mean maintenance-free.

Subaru Forester vs XV Australia: Which Is Better?

Oil changes, cooling-system condition, ignition components, and proper lubrication remain essential.

Potential problems can include oil leaks, sensor failures, and other age-related wear.

The exact FB25 variant also matters. We should not assume every engine bearing the FB25 name has identical reliability characteristics.

2.0-Liter Naturally Aspirated Boxer Engine

Some Forester markets offer 2.0-liter naturally aspirated petrol engines.

These engines can be attractive for buyers who value modest performance and mechanical simplicity.

However, reliability depends on the particular engine generation, maintenance history, and operating conditions.

We should compare a specific 2.0-liter model with its direct alternatives rather than assume it is automatically more reliable because of its smaller displacement.

Turbocharged Subaru Forester Engines

Turbocharged Foresters offer stronger acceleration and can be enjoyable to drive.

Older XT variants are particularly popular among Subaru enthusiasts.

However, a turbocharged engine introduces additional components, heat, and maintenance considerations.

Potential expenses include turbocharger repairs, related oil-system problems, and higher costs associated with neglected maintenance.

For someone purchasing primarily for performance, these trade-offs may be worthwhile.

For someone whose main priority is long-term dependability and predictable expenses, we would generally favor a naturally aspirated Forester.

What About the Subaru Forester Diesel?

Diesel-powered Foresters were available in some markets, including Australia and Europe.

They offer appealing fuel economy and torque characteristics, but certain Subaru Boxer diesel applications have experienced expensive mechanical problems.

Issues involving emissions equipment, particulate filters, and engine-related components can significantly increase ownership costs.

Because engine specification and production year matter greatly, we would recommend a specialist inspection before purchasing an older diesel Forester.

Is the Subaru Forester CVT Reliable?

The continuously variable transmission is one of the most discussed components among Subaru owners.

A CVT operates differently from a conventional stepped automatic transmission.

Instead of selecting a series of fixed mechanical gear ratios, it continuously adjusts its operating ratio to suit driving conditions.

This can improve efficiency and help deliver smooth acceleration.

However, CVT repairs can be expensive.

Common Subaru Forester CVT Problems

Symptoms worth investigating include:

• Hesitation when accelerating.
• Shuddering or vibration under load.
• Whining or other unusual transmission noises.
• Delayed engagement when selecting Drive or Reverse.
• Transmission temperature warnings.
• Sudden changes in engine speed without corresponding acceleration.

These symptoms do not always indicate a failed transmission.

Engine problems, sensors, mounts, and other components can produce similar behavior.

A qualified Subaru technician should determine the actual cause.

Are Newer Forester CVTs Better?

The Lineartronic CVT has been used and developed over multiple Forester generations.

The 2022–2024 models benefit from the extensive production history of this transmission family.

That is one reason we prefer these years over some older CVT-equipped examples.

Nevertheless, we would still check for evidence of proper transmission maintenance and ensure that the vehicle drives smoothly during a thorough road test.

How Can We Protect a Forester CVT?

Appropriate driving and maintenance habits can help minimize unnecessary wear.

We recommend following Subaru's transmission service instructions for the specific model and market, checking for fluid leaks, and addressing unusual behavior promptly.

If the vehicle has been used extensively for towing, mountain driving, or other demanding conditions, we should discuss the appropriate maintenance schedule with a qualified technician.

CVT fluid requirements differ by model, and using the wrong fluid or an incorrect servicing procedure can create serious problems.

How Long Does a Reliable Subaru Forester Last?

A well-maintained Subaru Forester can remain useful well beyond 150,000 miles (approximately 241,000 kilometers).

Some examples exceed 200,000 miles, or roughly 322,000 kilometers.

However, those figures should be understood as possible outcomes rather than guaranteed lifespans.

The distance a Forester can travel depends on several factors.

Maintenance History

Regular maintenance is one of the most important factors affecting longevity.

A Forester that receives timely oil changes, cooling-system inspections, and appropriate fluid services has a better chance of lasting many years.

Driving Conditions

Long highway journeys often place different demands on a vehicle than frequent short trips in heavy traffic.

Repeated cold starts, mountainous terrain, towing, and severe weather can affect wear and maintenance needs.

Previous Repairs

A Forester with 120,000 miles and comprehensive service records may be a safer purchase than one with 70,000 miles and no documented maintenance.

Mileage alone does not reveal whether important repairs have been neglected.

Owner Behavior

Checking fluid levels, responding to warning lights, and investigating unusual noises can help prevent relatively small problems from developing into expensive failures.

The way a vehicle has been driven and maintained can matter as much as its model year.

Subaru Forester Reliability After 100,000 Miles

Buying a Forester with more than 100,000 miles is not necessarily a bad decision.

However, we would focus more heavily on wear-related components.

Important inspection areas include:

At higher mileage, we would also budget for normal wear items such as tires, brakes, suspension components, and the battery.

A good pre-purchase inspection can identify many of these concerns before they become our responsibility.

Which Subaru Forester Trim Is Most Reliable?

Trim levels generally have less influence on reliability than the engine, transmission, maintenance history, and model year.

For example, US-market 2023 Forester Base, Premium, Sport, Limited, Touring, and Wilderness models all use a naturally aspirated 2.5-liter engine, although equipment and certain drivetrain specifications vary.

Subaru Forester Base and Premium

These trims are particularly attractive for buyers prioritizing practicality.

They offer the essential Forester characteristics without every available comfort feature.

Fewer optional electronic components may reduce the number of potential accessory-related repairs, although this does not automatically make them mechanically more reliable.

Subaru Forester Sport

The Sport trim adds visual and equipment differences while retaining the basic naturally aspirated powertrain in the US market.

Subaru Forester Best Years Australia: Most Reliable Models and Years to Avoid

For many buyers, this is a good balance between appearance, equipment, and everyday usability.

Subaru Forester Limited and Touring

Higher trims add comfort and convenience equipment.

These features can improve the ownership experience, but some may introduce additional repair costs as a vehicle ages.

If we want the lowest possible long-term expenses, we should decide whether every extra feature is necessary.

Subaru Forester Wilderness

The Wilderness version is designed for drivers who want additional capability on rough roads.

It uses modified gearing and off-road-oriented equipment compared with standard models.

It can be an excellent choice for outdoor activities, but off-road use and additional mechanical demands should be considered when inspecting a used example.

For mostly urban and highway driving, a regular Forester Premium or Sport may make more financial sense.

Subaru Forester Reliability in Australia

Australian buyers should be aware that Forester engine options and equipment can differ from those sold in the United States.

Australia has offered petrol, diesel, and e-Boxer hybrid variants across different generations.

Consequently, reliability conclusions based on US-market Foresters cannot always be applied directly to Australian vehicles.

For Australian drivers, we would generally prioritize a well-maintained 2022–2024 naturally aspirated petrol Forester, while also considering the vehicle's exact engine specification and service history.

A petrol model may appeal to buyers seeking a conventional drivetrain, whereas an e-Boxer version offers different efficiency and driving characteristics.

Neither should be declared universally more reliable without comparing the relevant model years and component histories.

Australian buyers should also check Subaru Australia's recall information and any market-specific service campaigns.

Is a Subaru Forester More Reliable Than a Toyota RAV4?

The Toyota RAV4 is one of the Forester's closest competitors.

Both vehicles are popular for family use and have established reputations for practicality.

However, the more reliable purchase depends on which model years and powertrains we're comparing.

Toyota offers conventional petrol and hybrid RAV4 variants, while Subaru focuses heavily on symmetrical all-wheel drive and Boxer engines.

The Forester stands out for its visibility, spacious cabin, and standard AWD in markets such as the United States.

The RAV4 may appeal to buyers who prefer Toyota's engine and transmission options, especially its established hybrid system.

Rather than assume one nameplate always wins, we would compare specific model years, independent reliability records, maintenance expenses, and individual vehicle condition.

How to Choose the Most Reliable Used Subaru Forester

Even if we've selected one of the most desirable model years, there are several checks worth completing before purchasing.

Check the Service Records

We should look for evidence of routine oil changes and other scheduled maintenance.

Unexplained gaps in service history deserve investigation, particularly on high-mileage vehicles.

A complete history does not guarantee reliability, but it helps us understand how the car has been maintained.

Inspect the Engine for Oil Leaks

Boxer engines can develop leaks at various seals and engine joints as they age.

Some repairs are relatively simple, while others require substantial labor.

We should inspect underneath the engine and ask about any history of oil consumption.

Test the CVT Thoroughly

During a test drive, we should evaluate acceleration, stopping, reversing, and steady highway cruising.

Unusual transmission behavior should never be dismissed without diagnosis.

Check the All-Wheel-Drive System

Subaru's AWD system depends on components operating together correctly.

We should inspect the differentials, axles, driveshafts, and tires.

Tires should meet Subaru's requirements for matching size, type, wear, and rolling circumference.

Significant mismatches can place unnecessary stress on AWD components.

Review Recalls and Warranty Campaigns

In the United States, recall information can be checked using the vehicle identification number.

We should also ask Subaru whether any applicable warranty extensions or technical campaigns remain relevant.

A completed safety recall is not the same thing as a manufacturer warranty extension, so both categories deserve attention.

Arrange an Independent Inspection

A qualified mechanic familiar with Subaru vehicles can identify problems that may not be obvious during a short test drive.

This is particularly important for vehicles with accident histories, high mileage, or incomplete maintenance records.

Is It Better to Buy a New or Used Subaru Forester?

A new Forester offers a manufacturer warranty, current safety technology, and the peace of mind of beginning with a vehicle that has not accumulated years of wear.

However, a newer design does not automatically have a stronger proven reliability record.

A used 2023 or 2024 Forester may offer better value because depreciation has already occurred and substantial ownership experience is available.

The right choice depends on our budget and priorities.

If we value the latest equipment and warranty coverage, a new model may be appropriate.

If we prioritize a proven design and lower purchase price, we would lean toward a carefully inspected late fifth-generation Forester.
