Subaru Forester 4th Generation Problems: Full Guide

The fourth-generation Subaru Forester is a popular compact SUV known for its spacious interior, all-wheel-drive capability, excellent visibility, and practical design. However, like any used vehicle, it has several potential reliability concerns that buyers should understand before making a purchase.

If we're researching Subaru Forester 4th generation problems, the most important issues to investigate include excessive engine oil consumption, continuously variable transmission (CVT) problems, suspension wear, wheel bearing failures, air conditioning faults, and electrical problems.

The fourth-generation Forester, known as the SJ series, was introduced in 2012 and sold in many markets from 2013 to 2018. In the United States, it corresponds to the 2014–2018 model years.

Despite its reputation as a practical and versatile SUV, not every engine or transmission combination offers the same ownership experience.

Some early models experienced engine oil consumption problems, while certain CVT-equipped vehicles developed transmission issues that could be expensive to repair.

In this comprehensive guide, we'll explore the most common Subaru Forester fourth-generation problems, their symptoms, potential repair costs, reliability differences between model years, and what to inspect before buying a used example.

Subaru Forester 4th Generation Overview

The fourth-generation Subaru Forester brought several improvements compared with its predecessor.

These included a more spacious cabin, improved fuel efficiency, updated technology, and additional driver assistance features.

Depending on the market, buyers could choose from several petrol and diesel engines, along with manual or CVT transmissions.

One of the Forester's biggest advantages is its symmetrical all-wheel-drive system, which provides additional traction in wet, slippery, and challenging road conditions.

However, the combination of boxer engines and CVT transmissions makes maintenance particularly important.

Most Common Subaru Forester 4th Generation Problems

Before examining individual faults, let's review the main mechanical and electrical issues worth investigating.

These problems do not affect every fourth-generation Forester.

Some are associated with particular engines, production years, driving conditions, or maintenance histories.

For this reason, we should evaluate each vehicle individually rather than assuming that every Forester will experience the same failures.

1. Excessive Engine Oil Consumption

Excessive engine oil consumption is one of the most significant concerns associated with certain early fourth-generation Subaru Forester models.

The problem primarily affected some vehicles equipped with naturally aspirated FB-series boxer engines.

What Causes Excessive Oil Consumption?

In certain engines, piston ring problems allowed more oil than expected to enter the combustion chambers.

As a result, the engine could consume oil between scheduled maintenance intervals.

Some affected vehicles required regular oil top-ups, while others needed more extensive engine repairs.

Subaru introduced an extended warranty program for excessive oil consumption on certain eligible vehicles in the United States.

The affected population included particular 2014 Forester 2.5L models and some 2015 models equipped with manual transmissions.

However, eligibility depended on the specific vehicle.

Symptoms of Excessive Oil Consumption

Common warning signs include:

• Engine oil level dropping between services.
• Frequent need to add engine oil.
• Low oil level warning lights.
• Burning oil smells.
• Blue exhaust smoke in severe cases.
• Unusual engine noises caused by inadequate lubrication.

The most important precaution is checking the engine oil level regularly.

Running an engine with insufficient oil can cause serious internal damage.

How to Fix Subaru Forester Oil Consumption

The appropriate repair depends on the underlying cause.

Minor oil loss may result from leaks, faulty seals, or problems with the crankcase ventilation system.

However, internal engine wear can require more substantial work.

In severe cases involving piston ring problems, replacing the engine short block may be necessary.

Before purchasing an early fourth-generation Forester, we recommend checking whether the vehicle has undergone oil consumption testing or previous engine repairs.

2. CVT Transmission Problems

The Subaru Lineartronic CVT is another important reliability concern.

Unlike a conventional automatic transmission with fixed gears, a CVT continuously adjusts its transmission ratio to provide smooth acceleration and improved efficiency.

Although many Forester CVTs operate reliably, some owners have experienced hesitation, shuddering, warning lights, and expensive transmission failures.

Common Subaru Forester CVT Symptoms

Typical warning signs include:

• Jerking during acceleration.
• Hesitation when moving from a standstill.
• Shuddering at low speeds.
• Delayed engagement when selecting Drive or Reverse.
• Whining noises from the transmission.
• Transmission overheating warnings.
• Engine speed increasing without normal acceleration.
• Dashboard warning lights.

Some changes in engine speed are normal with a CVT.

However, persistent vibration, slipping sensations, or unusual noises should be investigated.

What Causes Forester CVT Problems?

Several components can contribute to transmission problems.

Potential causes include:

• Faulty transmission valve body.
• Defective solenoids.
• Hydraulic pressure problems.
• Transmission fluid deterioration.
• Incorrect transmission fluid.
• Internal mechanical wear.
• Electronic control faults.

A malfunctioning valve body can sometimes be repaired without replacing the entire transmission.

However, internal mechanical failures may require much more expensive repairs.

Subaru Forester CVT Warranty Extension

Subaru introduced extended CVT warranty coverage for certain model years in the United States.

Eligible vehicles received coverage of up to 10 years or 100,000 miles, whichever occurred first.

These programs covered particular vehicles and were not equivalent to a universal recall of all Forester transmissions.

Most original coverage periods for fourth-generation vehicles have now expired or are approaching expiration.

We should always verify the specific vehicle's warranty and repair history.

How Much Does a Subaru Forester CVT Repair Cost?

Repair expenses vary significantly.

A valve body replacement may cost considerably less than replacing the complete transmission.

A full CVT replacement can cost several thousand dollars, particularly when using a new original-equipment transmission.

Because of this, a thorough test drive and professional inspection are essential before buying a CVT-equipped Forester.

3. Front Lower Control Arm Bushing Problems

Suspension wear is another commonly reported concern.

The front lower control arm bushings are particularly important because they help control suspension movement and absorb vibration.

Over time, these rubber components can deteriorate, crack, or develop excessive movement.

Symptoms of Worn Control Arm Bushings

We may notice:

• Knocking sounds over bumps.
• Steering wheel vibration.
• Clunking during acceleration or braking.
• Reduced steering precision.
• Uneven tyre wear.
• Instability when cornering.

Subaru issued technical service guidance addressing front lower control arm bushing concerns on certain fourth-generation Foresters.

The issue can become more noticeable as mileage increases.

How to Repair Worn Bushings

The repair generally involves replacing the worn bushings or complete control arm assemblies.

Replacing the entire control arm can sometimes be more practical than pressing out individual bushings.

A wheel alignment should normally follow suspension component replacement.

Ignoring worn bushings can lead to additional tyre wear and reduced handling precision.

4. Rear Suspension Spring Problems

Certain fourth-generation Foresters experienced corrosion-related rear coil spring problems.

In some vehicles, damage to the protective coating allowed corrosion to weaken the springs.

Over time, this could lead to spring fractures.

Which Subaru Forester Years Were Affected?

In the United States, Subaru introduced a service program covering certain 2014–2016 Foresters.

The program addressed rear coil springs that could deteriorate under particular corrosion conditions.

However, not every vehicle from these model years was included.

Symptoms of Broken Rear Springs

Potential signs include:

• Uneven rear ride height.
• Metallic noises from the suspension.
• A rear corner sitting lower than normal.
• Changes in vehicle handling.
• Visible broken spring sections.
• Excessive rust around suspension components.

A broken suspension spring can create safety risks and should be repaired promptly.

Can Rear Spring Problems Be Prevented?

Regular suspension inspections can help identify corrosion and early damage.

Vehicles driven in areas where roads are treated with salt deserve additional attention.

When purchasing a used Forester, we recommend checking whether any applicable spring-related service campaign was completed.

5. Wheel Bearing Problems

Wheel bearing wear is another problem that may develop as a Forester accumulates mileage.

Wheel bearings allow the wheels to rotate smoothly while supporting the vehicle's weight.

When a bearing begins to fail, it often produces a humming or grinding noise.

Signs of a Bad Wheel Bearing

Common symptoms include:

• Humming noises that increase with speed.
• Grinding sounds from one wheel.
• Rumbling during highway driving.
• Changes in noise while turning.
• Steering vibration.
• Excessive wheel movement in advanced cases.

A worn tyre can sometimes produce similar noises, so proper diagnosis is important.

How Much Does Wheel Bearing Replacement Cost?

Wheel bearing replacement generally costs less than major engine or transmission repairs.

However, the total price depends on the affected wheel, labour rates, and whether additional components require replacement.

A professional inspection can confirm which bearing needs attention.

6. Air Conditioning Compressor Problems

Air conditioning problems are another potential weakness of the fourth-generation Forester.

Some owners have experienced inconsistent cooling, unusual compressor noises, or complete A/C failure.

Common Air Conditioning Symptoms

Typical complaints include:

• Air conditioning blowing warm air.
• Cooling that works intermittently.
• Unusual noises when the A/C is switched on.
• Compressor clutch problems.
• Reduced cooling performance in hot weather.

What Causes Subaru Forester A/C Problems?

Possible causes include:

• Faulty compressor clutch.
• Refrigerant leaks.
• Compressor wear.
• Electrical problems.
• Faulty pressure sensors.
• Condenser damage.

Subaru introduced revised A/C compressor components for certain models after receiving complaints about cooling performance.

How to Fix the Air Conditioning

Before replacing the compressor, a qualified technician should check refrigerant pressures, electrical connections, and system operation.

Adding refrigerant without locating a leak is not a permanent solution.

Some faults may require relatively minor repairs, while compressor replacement can be considerably more expensive.

7. Battery Drain and Electrical Problems

Electrical faults can become more noticeable as the vehicle ages.

Some Forester owners report battery discharge, intermittent starting problems, and dashboard warning lights.

Common Electrical Problems

Possible symptoms include:

• Slow engine cranking.
• Battery going flat while parked.
• Intermittent no-start conditions.
• Dashboard warning lights.
• Electrical accessories malfunctioning.
• Infotainment system restarting.

What Causes Battery Drain?

A flat battery can result from several different issues.

These include an ageing battery, charging system problems, loose connections, or an electrical component drawing power while the vehicle is switched off.

Aftermarket accessories can also contribute to parasitic battery drain.

How to Diagnose Electrical Problems

We recommend testing the battery and alternator before replacing components.

If the battery repeatedly loses charge, a technician should check for excessive parasitic electrical draw.

Proper diagnosis helps avoid unnecessary replacement of expensive electronic parts.

8. Subaru Forester XT Turbocharger Problems

The fourth-generation Forester XT uses a turbocharged 2.0-litre petrol engine.

This version offers stronger acceleration and better performance than naturally aspirated alternatives.

Hyundai i30 Radio Not Working? Causes and Fixes

However, the additional complexity of turbocharging introduces maintenance considerations.

Common Turbocharged Engine Problems

Potential warning signs include:

• Reduced engine performance.
• Unusual turbocharger noises.
• Excessive exhaust smoke.
• Irregular acceleration.
• Engine warning lights.
• Oil leaks.
• Increased oil consumption.

These symptoms do not automatically mean the turbocharger has failed.

Problems involving ignition coils, sensors, intake hoses, or fuel delivery can produce similar behaviour.

Carbon Buildup in Direct-Injection Engines

The Forester XT uses direct fuel injection.

Unlike traditional port injection, direct injection does not continuously wash fuel over the intake valves.

Over time, carbon deposits may accumulate.

Heavy deposits can contribute to rough idling, hesitation, or reduced performance.

How to Maintain a Forester XT

We recommend following these precautions:

• Use the correct engine oil.
• Follow the recommended servicing schedule.
• Investigate oil leaks promptly.
• Keep the cooling system in good condition.
• Check intake and turbocharger connections.
• Use the fuel grade specified by Subaru.

A well-maintained Forester XT can provide an enjoyable driving experience, but neglected examples can become expensive to repair.

9. Subaru Forester Diesel Problems

In markets such as Australia and Europe, the fourth-generation Forester was offered with a 2.0-litre turbo diesel boxer engine.

The diesel version provides strong torque and can be economical during longer journeys.

However, diesel models have additional components that require careful maintenance.

Diesel Particulate Filter Problems

One concern is the diesel particulate filter, commonly called the DPF.

This component traps soot from exhaust gases and periodically burns accumulated particles during regeneration.

Repeated short journeys and interrupted regeneration cycles can contribute to DPF blockage.

Symptoms of DPF Problems

Common symptoms include:

• DPF warning lights.
• Reduced engine power.
• Increased fuel consumption.
• Frequent regeneration attempts.
• Engine warning lights.
• Unusual exhaust smells.

A blocked DPF should be diagnosed before attempting repairs.

The underlying cause may involve sensors, operating conditions, or other engine management problems.

Diesel Engine Oil Dilution

Interrupted DPF regeneration can sometimes allow diesel fuel to contaminate engine oil.

This may cause the engine oil level to rise.

Fuel dilution can reduce lubrication effectiveness and contribute to engine wear.

An unexpectedly increasing oil level should be investigated promptly.

Is the Subaru Forester Diesel Reliable?

Diesel Foresters can suit drivers who regularly travel longer distances.

However, vehicles used mainly for short urban journeys may be more vulnerable to DPF-related problems.

We would prioritise diesel models with complete service records and no unresolved emissions-system warnings.

10. Engine Oil Leaks

External engine oil leaks can develop as fourth-generation Foresters age.

Potential leak locations include valve cover seals, timing cover joints, and other engine sealing surfaces.

Symptoms of Engine Oil Leaks

Common signs include:

• Oil spots beneath the vehicle.
• Visible oil residue around the engine.
• Burning oil smells.
• Smoke from oil contacting hot components.
• Gradually decreasing oil levels.

Small amounts of seepage are not necessarily evidence of serious engine damage.

However, active leaks should be identified and repaired before they worsen.

11. Infotainment and Bluetooth Problems

The fourth-generation Forester's infotainment technology is relatively basic compared with modern SUVs.

Some owners experience connectivity problems, touchscreen faults, or occasional system freezing.

Common Infotainment Issues

Reported symptoms include:

• Bluetooth failing to connect.
• Phone calls disconnecting.
• Touchscreen becoming unresponsive.
• Audio cutting out.
• Slow system operation.
• Smartphone compatibility problems.

How to Fix Infotainment Problems

Possible solutions include resetting the system, removing old Bluetooth pairings, checking for software updates, or replacing faulty components.

Although frustrating, these problems are generally less concerning than major powertrain faults.

12. Subaru Forester Safety Recalls

Official safety recalls are another important consideration when buying a used vehicle.

Certain fourth-generation Foresters were included in recalls involving airbag occupant detection systems and brake light switches.

Passenger Airbag Detection Problems

Some 2015–2018 Foresters in the United States were recalled because an electrical connection could interfere with the front passenger occupant detection system.

Under certain circumstances, the system could incorrectly deactivate the passenger airbag.

Owners should verify whether any applicable recall repair has been completed.

Brake Light Switch Problems

Certain 2014–2016 Foresters were also recalled for a brake light switch issue.

A malfunctioning switch could prevent brake lights from illuminating and potentially interfere with starting or shifting functions.

Recall applicability depends on the individual VIN and market.

Before purchasing, we recommend checking the vehicle's recall history with Subaru or the appropriate national vehicle safety authority.

Subaru Forester 4th Generation Repair Costs

Repair expenses depend on the country, labour rates, parts availability, and the severity of the fault.

The following figures are broad US-dollar estimates for budgeting purposes, not guaranteed workshop quotations.

These estimates illustrate why understanding the vehicle's maintenance history is so important.

A relatively inexpensive Forester with a failing transmission may ultimately cost more than a better-maintained example.

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

Subaru Forester 4th Generation Problems by Year

Reliability concerns vary across the fourth-generation production period.

Early models received particular attention for engine oil consumption, while later vehicles benefited from ongoing manufacturing improvements.

These assessments are general buying guidance rather than statistical failure rankings.

A vehicle's mechanical condition and servicing history should carry more weight than its model year alone.
