Subaru Forester Issues: Common Problems, Reliability, and Years to Avoid

The Subaru Forester has earned a strong reputation for practicality, all-wheel-drive capability, excellent visibility, and everyday comfort. Whether we're driving through snowy roads, exploring mountain trails, or commuting around town, this compact SUV offers plenty of reasons to consider it.

However, Subaru Forester issues are worth understanding before purchasing a used model or deciding whether to keep an older vehicle.

Like most vehicles, the Forester has experienced mechanical and electrical problems across different generations. Some are relatively minor, such as infotainment glitches and worn suspension components. Others, including excessive oil consumption, continuously variable transmission (CVT) failures, and cooling system problems, can become expensive.

The important detail is that not every Forester suffers from the same faults. Reliability varies considerably depending on the production year, engine, transmission, mileage, and maintenance history.

In this guide, we'll explore the most commonly reported Subaru Forester problems, identify the model years that deserve closer inspection, explain warning signs, and discuss ways to reduce long-term repair expenses.

Are Subaru Foresters Reliable?

Overall, the Subaru Forester is a reasonably dependable compact SUV, particularly when maintained correctly.

Its standard all-wheel-drive system on most markets' conventional petrol models, practical cabin, and capable suspension make it attractive to families and drivers who regularly encounter challenging weather conditions.

Nevertheless, Forester reliability isn't identical across every generation.

Older examples may develop head gasket problems, while certain vehicles manufactured during the early 2010s experienced excessive engine oil consumption. Some fourth-generation models have generated complaints involving their CVT transmissions, and early fifth-generation vehicles experienced thermo control valve problems.

Subaru Forester Reliability Ratings

RepairPal gives the Subaru Forester a reliability rating of approximately 3.5 out of 5 and estimates average annual repair and maintenance expenses of around $632 in the United States.

This suggests that ownership costs are manageable overall, although individual repairs can be expensive.

We should remember that an average maintenance figure doesn't guarantee inexpensive ownership. A well-maintained Forester might require little more than routine servicing in a given year, while another vehicle could need a major transmission or engine repair.

What Makes a Subaru Forester Reliable?

Several characteristics contribute to the Forester's reputation:

• A well-established all-wheel-drive platform.
• Naturally aspirated petrol engines in many popular versions.
• Practical mechanical construction and good parts availability.
• Comfortable suspension designed for everyday driving.
• Strong aftermarket and specialist repair support.

However, regular oil changes, cooling system maintenance, proper tyre care, and transmission servicing remain essential.

Most Common Subaru Forester Issues

Although the exact problems depend on the model year, several complaints appear repeatedly in owner discussions, technical bulletins, and vehicle repair records.

These are areas to investigate, not proof that every vehicle in the listed years will experience a failure.

Let's examine each problem more closely.

1. Subaru Forester Engine Problems

Engine-related complaints are among the most significant concerns when evaluating a used Subaru Forester.

While many engines deliver long service lives, certain generations have experienced oil consumption, leaks, overheating, or component failures.

Excessive Engine Oil Consumption

One widely discussed Subaru Forester issue involves engines using more oil than expected between scheduled services.

Certain Foresters built between 2011 and 2015 were included in a US class-action settlement involving allegations of excessive oil consumption. Eligibility depended on factors including model year, transmission type, and vehicle identification information.

Possible symptoms include:

• The engine oil warning light illuminating.
• Frequent top-ups between oil changes.
• Oil levels dropping unexpectedly.
• Engine noise caused by insufficient lubrication.
• Increased exhaust smoke in some cases.

Oil consumption can occur without a visible external leak, making it particularly important to check the dipstick regularly.

What Causes Excessive Oil Consumption?

Several mechanical conditions can allow engine oil to enter the combustion chamber, including worn piston rings, cylinder wear, or problems involving the crankcase ventilation system.

Early FB-series engines attracted attention for oil-control-related concerns.

However, we shouldn't assume that every low-oil complaint has the same underlying cause. A proper oil consumption test and inspection help distinguish internal consumption from external leakage.

How Can We Prevent Engine Damage?

We recommend checking oil levels regularly, particularly on an older Forester with an uncertain maintenance history.

If the engine consistently needs topping up, record how much oil is added and the distance travelled. A qualified mechanic can then assess whether the consumption is excessive.

Ignoring low oil levels can result in accelerated engine wear or catastrophic failure.

Subaru Forester Head Gasket Problems

Head gasket failure is another well-known issue associated with older Subaru boxer engines.

It is particularly relevant to older naturally aspirated EJ25 engines, including Foresters manufactured before the introduction of the newer FB25 engine in many markets.

The head gasket seals the connection between the engine block and cylinder head, preventing coolant, oil, and combustion gases from entering the wrong passages.

When the gasket deteriorates, fluids can escape externally or leak internally.

Symptoms of Head Gasket Failure

Common warning signs include:

• Engine overheating.
• Persistent coolant loss.
• Visible oil or coolant leakage around the engine.
• White exhaust smoke in certain types of failure.
• Bubbles in the cooling system.
• Unexplained pressure buildup in the coolant reservoir.
• Milky or contaminated engine oil in severe cases.

Not every head gasket failure produces every symptom.

Older Foresters can experience external gasket leaks without immediately overheating, which is why a careful inspection is important.

Are Newer Subaru Foresters Affected?

The head gasket problems commonly associated with older Subaru engines should not automatically be attributed to modern Foresters.

Later FB-series engines use a different design and don't share the same widespread historical head gasket pattern.

Nevertheless, overheating, poor coolant maintenance, or other mechanical damage can still cause head gasket failure in virtually any vehicle.

2. Subaru Forester CVT Transmission Issues

The continuously variable transmission is one of the most important components to examine when purchasing a used Subaru Forester.

CVTs operate differently from conventional automatic transmissions. Instead of using a fixed number of traditional gears, they continuously adjust their drive ratios.

This helps provide smooth acceleration and fuel efficiency.

However, some Subaru owners have reported transmission hesitation, jerking, unusual noises, and expensive repair requirements.

Common Symptoms of CVT Problems

Potential warning signs include:

• Hesitation when accelerating.
• Jerking or shuddering at low speeds.
• Delayed engagement when selecting Drive or Reverse.
• Whining or unusual transmission noises.
• Transmission temperature warnings.
• Engine revs increasing without a corresponding increase in vehicle speed.
• Unusual vibrations while driving.

A small amount of characteristic CVT behaviour doesn't automatically indicate failure.

However, repeated hesitation, shuddering, or transmission warning lights should be investigated.

Which Subaru Forester Years Have CVT Problems?

The fourth-generation Forester, particularly vehicles manufactured between 2014 and 2018, deserves attention when assessing transmission condition.

Subaru introduced warranty enhancement programmes for certain CVT-equipped vehicles in various markets.

In the United States, qualifying vehicles received extensions covering their transmissions for up to 10 years or 100,000 miles, depending on the applicable programme.

These extensions do not mean every affected vehicle has a defective transmission.

They also don't guarantee that a particular used Forester still qualifies for free repairs.

How Expensive Is a Forester CVT Repair?

Repair expenses depend on the component involved.

A transmission problem might require electrical diagnosis, valve body replacement, wiring repairs, or more extensive mechanical work.

Complete transmission replacement is substantially more expensive than correcting a minor electrical fault.

For this reason, we recommend avoiding a used Forester with unexplained transmission symptoms unless a qualified specialist has diagnosed the problem and the purchase price properly reflects the required repair.

How to Reduce CVT Problems

Good habits include:

• Following the applicable Subaru maintenance schedule.
• Using only the correct transmission fluid specification.
• Avoiding excessive towing loads.
• Addressing transmission overheating warnings promptly.
• Inspecting fluid leaks.
• Investigating abnormal driving behaviour early.

When buying used, transmission service history can be especially valuable.

3. Subaru Forester Thermo Control Valve Failure

One of the most noteworthy issues affecting newer-generation Subaru Foresters involves the thermo control valve, often abbreviated as TCV.

This component helps regulate coolant flow and manage engine operating temperature.

Certain 2019, 2020, and 2021 Subaru Foresters experienced failures associated with the valve assembly.

Symptoms of Thermo Control Valve Failure

Owners may notice:

• Check engine light illumination.
• Engine temperature management problems.
• Poor cabin heater performance.
• Multiple dashboard warnings.
• EyeSight driver-assistance functions becoming temporarily unavailable.
• Diagnostic trouble codes related to the thermo control valve.

The appearance of several warning messages at once can be concerning, but those messages don't necessarily mean that every indicated vehicle system has failed independently.

Is the Subaru Forester Thermo Control Valve Covered?

Subaru of America issued service bulletin 09-119-24, extending thermo control valve warranty coverage to 15 years or 150,000 miles for eligible 2019–2021 Forester vehicles.

The bulletin also describes an improved replacement component.

Coverage depends on eligibility, vehicle history, market, and warranty conditions.

If we're buying a 2019–2021 Forester, checking whether the valve has already been replaced is an excellent precaution.

4. Subaru Forester Battery Drain Problems

Battery-related complaints appear across several Forester model years.

Drivers sometimes report that their vehicles struggle to start after sitting unused, even when the battery seems relatively new.

Signs of Electrical or Battery Problems

Typical symptoms include:

• Slow engine cranking.
• Clicking sounds when starting.
• A completely discharged battery.
• Interior lights behaving unexpectedly.
• Electrical warning messages.
• Stop-start functionality becoming unavailable.
• Electronic accessories resetting.

Although these symptoms may indicate a weak battery, other explanations are possible.

Why Does the Battery Keep Dying?

Potential causes include:

• An ageing or defective battery.
• A charging system malfunction.
• Excessive electrical consumption while parked.
• Poor electrical connections.
• Short driving journeys that don't adequately recharge the battery.
• A malfunctioning electrical module.

Some vehicles with automatic engine stop-start systems may require batteries with specific capabilities.

Subaru Forester Boot Not Opening? Causes and Fixes

Installing an unsuitable replacement can create additional problems.

How to Fix Battery Drain

We suggest having the battery and charging system tested before purchasing a replacement.

If the battery repeatedly discharges while the vehicle is parked, a parasitic draw test can help identify whether an electrical component is consuming excessive power.

Replacing the battery without identifying the underlying cause may provide only temporary relief.

5. Subaru Forester Windshield Cracking Issues

Windshield damage has been a prominent complaint involving certain newer Subaru Foresters.

Some owners have reported cracks developing with little or no obvious impact.

Complaints have been particularly notable among 2019–2022 Forester models.

Why Is Windshield Replacement Expensive?

Modern Foresters may include Subaru's EyeSight driver-assistance technology, which uses forward-facing cameras mounted near the windshield.

Replacing the windshield can require careful attention to glass specifications and camera calibration.

This makes some windshield replacements more involved than those on older vehicles without advanced driver-assistance features.

Is There a Windshield Warranty Extension?

In the United States, a class-action settlement involving certain Subaru vehicles, including 2019–2022 Foresters, resulted in provisions for qualifying windshield-related claims and extended coverage.

Specific eligibility criteria apply.

Before paying for a replacement, we recommend checking whether the vehicle qualifies for any available warranty or settlement benefits.

6. Subaru Forester Oil Leak Problems

Oil leaks are another concern worth investigating, particularly on older or higher-mileage Foresters.

Because Subaru uses horizontally opposed engines, certain seals and sealing surfaces can require significant labour to access.

Common Oil Leak Locations

Possible sources include:

• Valve cover gaskets.
• Cam carrier sealing surfaces.
• Timing cover areas.
• Oil pan seals.
• Oil pressure switches.
• Crankshaft seals.

Not all oil leaks require major repairs.

A small amount of seepage may be manageable, while an active leak that causes oil loss or contacts hot exhaust components should receive prompt attention.

How to Identify an Oil Leak

We can inspect the ground beneath the parked vehicle and look for fresh oil deposits.

Other warning signs include a burning oil smell, visible smoke from the engine compartment, or oil collecting around the lower engine.

A mechanic may need to clean the engine and use leak-detection methods to determine the exact source.

It's important not to confuse a cam carrier leak with a head gasket failure, because the diagnosis and repair procedures are different.

7. Subaru Forester Suspension and Wheel Bearing Problems

Suspension components gradually deteriorate with mileage, road conditions, and driving habits.

The Forester is often used on rough roads, gravel tracks, and uneven surfaces, making suspension maintenance particularly important.

Common Suspension Complaints

Potential issues include:

• Worn control arm bushings.
• Noisy wheel bearings.
• Deteriorating sway bar links.
• Damaged shock absorbers.
• Uneven tyre wear.
• Steering vibrations.
• Knocking noises when travelling over bumps.

How to Recognise a Bad Wheel Bearing

A failing wheel bearing may produce a humming, grinding, or rumbling noise that changes as the vehicle accelerates.

The sound can sometimes become louder when the vehicle turns.

However, unevenly worn tyres can create similar noises.

We recommend professional inspection rather than replacing wheel bearings based on sound alone.

8. Subaru Forester Air Conditioning Problems

Air conditioning complaints can involve weak cooling performance, unusual compressor noises, or intermittent operation.

These symptoms can become especially inconvenient during hot weather.

What Causes Forester AC Issues?

Possible causes include:

• Refrigerant leaks.
• Compressor or clutch problems.
• Faulty pressure sensors.
• Condenser damage.
• Electrical faults.
• Cabin airflow restrictions.

Before replacing the compressor, the system should be properly diagnosed.

A refrigerant leak, for example, might cause cooling problems even when the compressor itself is operating correctly.

Can We Prevent Air Conditioning Failures?

Routine maintenance helps.

We recommend replacing the cabin air filter when required, clearing debris from the condenser area, and investigating reduced cooling performance before the problem becomes severe.

9. Subaru Forester EyeSight and Infotainment Issues

Modern Subaru Foresters offer useful driver-assistance and infotainment technology.

However, some owners experience software glitches, intermittent warning messages, or connectivity problems.

Common Infotainment Complaints

These may include:

• Touchscreen freezing.
• Delayed screen responses.
• Bluetooth connection failures.
• Smartphone connectivity problems.
• Unexpected system restarts.
• Navigation or audio interruptions.

Software updates may resolve some problems, while others require hardware diagnosis.

Subaru EyeSight Warning Problems

EyeSight relies on cameras and other vehicle systems to provide driver-assistance functions.

Its operation can be affected by:

• Heavy rain, snow, or fog.
• Windshield obstruction.
• Camera contamination.
• Incorrect windshield installation or calibration.
• Certain engine or electrical faults.

A temporary EyeSight unavailable message isn't necessarily evidence of a defective camera.

However, persistent warning messages need professional diagnosis.

Because EyeSight includes safety-related functions, we shouldn't ignore a recurring fault.

10. Subaru Forester Automatic Start-Stop Issues

Automatic start-stop technology is designed to reduce fuel consumption by switching the engine off during suitable stationary conditions.

Although useful in certain driving situations, some Forester owners dislike how the system operates.

Reported concerns include noticeable engine restarts, occasional hesitation, and situations where the system doesn't activate as expected.

Why Might Auto Start-Stop Stop Working?

Several conditions influence operation:

• Battery charge level.
• Engine temperature.
• Cabin climate-control demand.
• Electrical system status.
• Vehicle operating conditions.

If the system operates inconsistently, the explanation may be a normal operating restriction rather than a mechanical failure.

However, repeated stalling, failure to restart, or unusual warning messages should be investigated promptly.

Subaru Forester Problems by Model Year

Understanding generation-specific problems is more useful than assuming every Subaru Forester has the same reliability record.

Subaru Forester 2009–2013 Issues

Older Foresters deserve attention for engine condition, cooling system health, and general age-related wear.

The early years of this period included EJ-series engines associated with head gasket concerns.

Later models introduced FB-series engines that brought different considerations, including excessive oil consumption in some vehicles.

Areas to inspect include:

• Head gasket condition on applicable older engines.
• Engine oil consumption.
• Cooling system leaks.
• Timing belt maintenance on engines equipped with one.
• Suspension wear.
• Rust or corrosion in regions with harsh winters.

A well-maintained example can still offer useful service, but missing maintenance documentation increases the financial risk.

Subaru Forester 2014–2018 Issues

The fourth-generation Forester introduced major changes, including wider use of CVT technology.

Common areas of concern include:

• CVT hesitation and abnormal operation.
• Oil consumption on certain early vehicles.
• Oil leaks.
• Battery and electrical faults.
• Suspension and wheel bearing wear.
• Windshield complaints on some later examples.

These model years aren't automatically poor purchases.

However, transmission condition and maintenance history deserve particularly careful attention.

Subaru Forester 2019–2021 Issues

The fifth-generation Forester brought updated technology, additional driver-assistance features, and improvements in comfort.

However, its early years developed several noteworthy complaint patterns.

These include:

• Thermo control valve failure.
• Windshield cracking.
• Battery discharge.
• Automatic start-stop concerns.
• Infotainment complaints.
• Engine-related warning messages.

Subaru's thermo control valve warranty extension is particularly relevant for eligible vehicles.

We recommend confirming completed repairs and examining the service record before purchasing.

Subaru Forester 2022–2024 Issues

Later fifth-generation models benefit from additional years of development.

Potential concerns still include:

• Electrical or infotainment glitches.
• Windshield damage.
• Battery-related complaints.
• Suspension wear.
• General mechanical maintenance issues.

These model years can be attractive used options, but individual condition remains more important than reputation alone.

A neglected 2023 Forester could be a worse purchase than a carefully maintained 2018 example.

Subaru Forester 2025–2026 Issues

The latest generation includes redesigned styling, updated technology, and hybrid availability in certain markets.

Because these vehicles are relatively new, there isn't enough long-term ownership evidence to establish how they will perform after many years of use.

Subaru Forester Diesel Problems: Common Faults

However, recall checks are particularly important.

In the United States, certain recent Forester vehicles have been involved in campaigns concerning issues such as power moonroof glass attachment, certification labels, and a fuel-cap sealing concern affecting certain 2025 Forester Hybrids.

A recall doesn't mean every Forester of the same model year is affected. Applicability depends on the specific vehicle.

We should verify outstanding campaigns using the VIN rather than relying solely on the production year.

Which Subaru Forester Years Should You Avoid?

There is no universally reliable list of Forester model years that everyone should avoid.

Different generations have different strengths and weaknesses, while ownership history has an enormous effect on long-term reliability.

Nevertheless, some production periods warrant greater caution.

We would be especially cautious with any Forester showing severe oil consumption, transmission hesitation, evidence of overheating, or recurring unexplained warning lights.

Those symptoms are more meaningful than model year alone.

How Much Does It Cost to Fix Subaru Forester Problems?

Repair expenses vary according to vehicle age, location, labour rates, the parts required, and the severity of the problem.

Minor electrical repairs may be relatively affordable.

By comparison, replacing a transmission or repairing major engine damage can cost thousands of dollars.

Typical Repair Cost Considerations

As a reference, US repair estimator RepairPal places average head gasket replacement expenses across vehicles at approximately $2,572–$3,386. Actual Forester quotes may fall outside that range.

Before authorising a major repair, we recommend asking whether the vehicle qualifies for an active recall, warranty extension, or other applicable service programme.

How Long Does a Subaru Forester Last?

A well-maintained Subaru Forester can potentially reach 200,000 miles or more.

However, this isn't a guaranteed lifespan.

Long-term durability depends on maintenance, driving conditions, accident history, and the condition of expensive components.

Some vehicles require major repairs long before reaching that mileage, while others remain serviceable well beyond it.

Can a Subaru Forester Reach 200,000 Miles?

Yes, it is possible.

To improve our chances, we should focus on:

• Regular engine oil and filter changes.
• Correct transmission maintenance.
• Cooling system inspections.
• Timely replacement of worn suspension parts.
• Routine checks for fluid leaks.
• Addressing diagnostic warning lights.
• Avoiding prolonged driving with low engine oil.
• Maintaining consistent tyre size, condition, and inflation across the all-wheel-drive system.

The last point is especially important because tyre differences can affect all-wheel-drive components.

What Mileage Is Too High for a Used Forester?

Mileage alone doesn't determine whether a Forester is worth buying.

A vehicle with 130,000 miles and thorough maintenance records might be preferable to one with 75,000 miles and a neglected transmission.

When evaluating higher-mileage examples, we should consider both repair history and the likelihood of expensive work in the near future.

How to Check a Used Subaru Forester Before Buying

A pre-purchase inspection is one of the simplest ways to avoid expensive surprises.

Even if the vehicle appears clean and drives normally, an independent Subaru specialist may identify problems that aren't immediately obvious.

Essential Used Forester Inspection Checklist

Engine and cooling system

• Check engine oil level and condition.
• Look for external fluid leaks.
• Inspect coolant condition and level.
• Watch for overheating or abnormal exhaust smoke.
• Review previous engine repairs.

Transmission and drivetrain

• Test acceleration from low speeds.
• Check for hesitation, shuddering, or abnormal noises.
• Confirm smooth engagement of Drive and Reverse.
• Inspect transmission leaks.
• Review service and warranty records.

Electrical and technology systems

• Test the battery and charging system.
• Check dashboard warning lights.
• Test infotainment and connectivity features.
• Confirm EyeSight operates correctly where equipped.
• Test climate control.

Suspension and body

• Listen for bearing noises.
• Inspect tyres for uneven wear.
• Check control arm bushings and shock absorbers.
• Examine the windshield carefully.
• Look for corrosion and accident repairs.

We should also verify the VIN through the appropriate national recall database and request documentation for any completed safety campaigns.

How to Prevent Common Subaru Forester Issues

Preventive maintenance cannot eliminate every manufacturing defect, but it can significantly reduce the risk of avoidable mechanical damage.

Follow the Correct Maintenance Schedule

Subaru maintenance requirements differ depending on the engine, model year, driving environment, and country.

We should consult the owner's manual rather than applying one generic service interval to every Forester.

For vehicles used in severe conditions, more frequent inspections or servicing may be appropriate.

Check Engine Oil Between Services

Oil monitoring is especially valuable on older engines with known consumption concerns.

A regular dipstick check can reveal a developing issue before lubrication becomes dangerously low.

Address Cooling System Problems Immediately

A small coolant leak can eventually lead to serious overheating.

If the temperature warning activates or the engine begins overheating, we should stop safely and investigate instead of continuing to drive.

Investigate CVT Symptoms Early

Transmission problems often become more expensive when abnormal behaviour is ignored.

Early diagnosis may reveal an electrical or control-related fault before more extensive damage occurs.

Maintain Matching Tyres

Subaru's all-wheel-drive system benefits from tyres with appropriate matching specifications and closely matched rolling circumference.

We should follow the manufacturer's recommendations when replacing tyres, including any restrictions on tread-depth differences.

Is a Used Subaru Forester Worth Buying?

For many drivers, the Subaru Forester remains an appealing used SUV.

Its practicality, high seating position, visibility, cargo space, and all-wheel-drive capability make it a sensible choice for families, commuters, and outdoor enthusiasts.

However, we should treat maintenance documentation as a major part of the purchase decision.

Reasons to Buy a Subaru Forester

• Practical and spacious interior.
• Confident all-wheel-drive capability.
• Comfortable driving position.
• Good outward visibility.
• Useful ground clearance.
• Wide availability of repair information.
• Strong everyday versatility.

Reasons to Think Twice

• Some historical engine and CVT problems can be expensive.
• Boxer engine repairs can require substantial labour.
• Certain years have notable windshield and electrical complaints.
• Modern driver-assistance systems may increase glass replacement complexity.
• A neglected example can become costly to maintain.

We would generally prefer a carefully maintained Forester with documented major repairs over a cheaper example with unknown mechanical history.

Subaru Forester Issues vs Other Compact SUVs

If we're comparing the Forester with competitors, it helps to understand what matters most in daily ownership.

No vehicle is immune to problems.

Instead of comparing brand reputation alone, we should evaluate specific years, engine options, maintenance histories, and likely repair costs.

Frequently Asked Questions About Subaru Forester Issues

1. What Is the Most Common Problem With the Subaru Forester?

There isn't one single problem that dominates every Forester generation.

Older models are often associated with head gasket leakage and excessive oil consumption, while certain fourth-generation vehicles have experienced CVT complaints.

For 2019–2021 models, thermo control valve failure is an important known concern. Windshield cracking has also attracted substantial complaints on several newer model years.

The most relevant issue depends on the vehicle being considered.

2. Which Subaru Forester Years Have the Most Problems?

Certain 2014–2018 vehicles deserve careful inspection for transmission and engine-related concerns.

The 2019 and 2020 models have also attracted substantial owner complaints, particularly involving windshield damage and electrical or engine-related symptoms.

However, complaint totals are not the same as failure rates. Sales volume, vehicle age, and reporting behaviour influence those figures.

3. Are Subaru Forester Transmission Problems Expensive to Fix?

They can be.

Minor electrical or control-related issues may cost significantly less than complete transmission replacement.

A Forester that hesitates, shudders, makes abnormal noises, or displays a transmission warning should receive professional diagnosis before purchase.

We also recommend checking whether an applicable warranty extension covers the problem.

4. Is the Subaru Forester a Good SUV for Long-Term Ownership?

Yes, it can be a good long-term vehicle when properly maintained.

The Forester offers practical features and capable all-wheel-drive performance, but it requires consistent servicing like any modern SUV.

Checking engine oil, maintaining the cooling system, monitoring transmission behaviour, and repairing minor faults early all help support long-term ownership.

5. Should I Buy a Subaru Forester With 100,000 Miles?

A Forester with 100,000 miles can still be worth buying, provided its mechanical condition is good.

We would look for comprehensive service records, evidence of proper transmission maintenance, no significant oil consumption, and no unresolved cooling system or electrical problems.

An independent inspection is particularly important at this mileage because major repairs can quickly offset an attractive purchase price.

Final Thoughts: Should You Worry About Subaru Forester Issues?

The Subaru Forester is a capable, comfortable, and practical SUV, but understanding its known weaknesses is essential before buying.

The most important concerns vary by generation. Older examples deserve special attention for head gasket leaks and oil consumption, some 2014–2018 models require careful CVT inspection, and eligible 2019–2021 vehicles should be checked for thermo control valve repairs.

Newer models have their own potential issues, although long-term reliability conclusions for the latest generation remain premature.

Our recommendation is to prioritise vehicle condition, documented maintenance, completed recall work, and a professional inspection over model year alone.

A Forester with a transparent service history and no unresolved mechanical symptoms can provide many years of enjoyable ownership.
