While Subaru has made great strides in engineering and design, certain years of the Forester have been plagued by recurring mechanical and electrical issues. These problems can range from minor annoyances to major repair expenses, affecting everything from engine performance to driver safety systems. Whether you’re buying new, used, or certified pre-owned, knowing which years to avoid—or at least approach with caution—can save you thousands in repairs and countless hours of frustration.

In this guide, we’ll dive deep into the worst years for the Subaru Forester. We’ll examine the most common problems reported by owners and mechanics, explain why these issues occur, and offer practical advice on how to avoid them. Whether you’re shopping for a used Forester or just curious about the model’s history, this article will arm you with the knowledge you need to make a smart decision.

Understanding Subaru Forester Generations and Model Evolution

Before we get into the problematic years, it helps to understand how the Forester has evolved over time. Subaru introduced the Forester in 1997 as a rugged, car-based alternative to traditional SUVs. Since then, it has gone through several generations, each bringing improvements in safety, fuel efficiency, and technology.

The second generation (2003–2008) introduced a more refined design and better crash test ratings. The third generation (2009–2013) brought a larger body, improved interior materials, and the debut of Subaru’s EyeSight driver-assist system. The fourth generation (2014–2018) marked a major redesign with a more modern look, better fuel economy, and a new 2.5L engine. Finally, the fifth generation (2019–present) introduced a new platform, updated infotainment, and enhanced safety features.

Each generation has its strengths and weaknesses. While newer models often come with advanced tech and improved safety, they can also introduce new problems—especially in the first few years of a redesign. That’s why it’s important to look beyond the year and consider the generation, engine type, and common failure points.

For example, the 2014–2018 models share the same 2.5L FB25 engine, which is generally reliable but has a known issue with oil consumption. Meanwhile, the 2019+ models use a newer FB25D engine and a revised CVT (continuously variable transmission), which have introduced new challenges. Understanding these generational differences helps explain why some years are worse than others.

The 2014–2015 Subaru Forester: Oil Consumption Nightmare

If there’s one issue that defined the 2014 and 2015 Subaru Forester, it’s excessive oil consumption. These model years are widely regarded as some of the worst in the Forester lineup due to a widespread problem with the 2.5L FB25 engine burning oil at an alarming rate.

What Is the Oil Consumption Problem?

Owners of 2014 and 2015 Foresters reported losing up to one quart of oil every 1,000 miles—sometimes even more. This isn’t just a minor inconvenience; it can lead to serious engine damage if not caught early. Low oil levels can cause increased friction, overheating, and eventually, catastrophic engine failure.

Subaru eventually acknowledged the issue and extended the powertrain warranty to 8 years or 100,000 miles for affected vehicles. However, many owners still had to pay out of pocket for repairs before the warranty extension was announced. Even with the extended coverage, the hassle of constantly checking and topping off oil is a major drawback.

Why Does This Happen?

The root cause lies in the design of the piston rings in the FB25 engine. These rings are responsible for sealing the combustion chamber and controlling oil flow. In the 2014–2015 models, the rings were not sealing properly, allowing oil to seep into the combustion chamber and burn off during operation.

This issue is more common in vehicles that are driven primarily on short trips or in stop-and-go traffic, where the engine doesn’t reach optimal operating temperature. Cold engines are more prone to oil burning because the piston rings don’t expand fully to create a tight seal.

How to Spot and Prevent the Problem

If you’re considering a 2014 or 2015 Forester, here’s what you can do:

– Check the oil level regularly: Use the dipstick every 500–1,000 miles and top off as needed.
– Ask for maintenance records: Look for frequent oil top-offs or engine repairs.
– Get a compression test: A mechanic can check cylinder compression to see if the piston rings are worn.
– Consider a used engine or rebuild: If the problem is severe, replacing the engine may be the only long-term fix.

While not every 2014–2015 Forester will have this issue, the risk is high enough that many experts recommend avoiding these years altogether—or at least factoring in the cost of potential repairs.

The 2019 Subaru Forester: CVT and EyeSight Glitches

The 2019 Subaru Forester marked the debut of the fifth generation, bringing a fresh design, improved fuel economy, and the latest version of Subaru’s EyeSight safety suite. Unfortunately, this newness came with a host of software and transmission issues that have frustrated many owners.

CVT Transmission Problems

The 2019 Forester uses a Lineartronic CVT (continuously variable transmission), which is designed to improve fuel efficiency and smoothness. However, many owners have reported jerky acceleration, hesitation, and a “rubber band” feeling when driving. Some have even experienced complete transmission failure within the first 30,000 miles.

The CVT is sensitive to software updates and driving habits. Subaru has released several technical service bulletins (TSBs) addressing shift logic and calibration issues, but not all dealerships apply these updates promptly. If you’re buying a used 2019 Forester, make sure the latest software has been installed.

EyeSight Safety System Malfunctions

EyeSight is one of Subaru’s standout features, offering adaptive cruise control, lane departure warning, and pre-collision braking. But in the 2019 model, the system has been known to behave erratically. Common complaints include:

– Sudden, unexpected braking (even when no obstacle is present)
– Failure to detect vehicles or pedestrians
– False lane departure warnings
– System going offline during drives

These glitches aren’t just annoying—they can be dangerous. False braking can cause rear-end collisions, and a malfunctioning safety system defeats the purpose of having advanced driver assistance in the first place.

Infotainment and Electrical Issues

The 2019 Forester also introduced a new 6.5-inch or 8-inch touchscreen infotainment system. While the design is modern, the software is buggy. Owners report freezing screens, unresponsive touch controls, and Bluetooth connectivity problems. Some have even had to replace the entire head unit under warranty.

Additionally, there have been reports of electrical gremlins, including malfunctioning power windows, faulty door locks, and dashboard warning lights that appear for no reason.

What You Can Do

If you’re set on a 2019 Forester, here are some tips:

– Verify software updates: Ask the dealer or previous owner if all TSBs and recalls have been addressed.
– Test drive thoroughly: Pay close attention to transmission behavior and EyeSight functionality.
– Check for open recalls: Use the NHTSA website to see if the vehicle has any unresolved safety recalls.
– Consider a certified pre-owned (CPO) model: CPO Foresters come with extended warranties and have been inspected for known issues.

While the 2019 Forester has potential, its teething problems make it a risky choice unless you’re prepared for possible repairs.

The 2013 Subaru Forester: Head Gasket Failures

The 2013 Subaru Forester is part of the third generation, which is generally reliable—except for one notorious flaw: head gasket failures. This issue isn’t unique to the 2013 model, but it’s especially common in Foresters from 2009 to 2013, particularly those with the 2.5L naturally aspirated engine.

Why Head Gaskets Fail

Subaru used a multi-layer steel (MLS) head gasket design in the early 2010s, which was supposed to be more durable than the older composite gaskets. However, the MLS gaskets in these engines were prone to failure due to poor sealing and thermal stress.

The head gasket sits between the engine block and cylinder head, sealing coolant and oil passages. When it fails, coolant can leak into the combustion chamber or oil passages, leading to white smoke from the exhaust, milky oil, and overheating.

Symptoms to Watch For

If you’re looking at a 2013 Forester, watch for these signs:

– Overheating: The engine runs hot, especially in traffic or on long drives.
– White exhaust smoke: Indicates coolant burning in the combustion chamber.
– Milky oil: Coolant mixing with oil creates a frothy, tan substance on the dipstick.
– Low coolant levels: Coolant disappears without visible leaks.

Repair Costs and Prevention

Replacing a head gasket is a major repair, typically costing $1,500 to $2,500. It involves removing the cylinder head, machining it if necessary, and installing a new gasket. Some owners have reported needing a full engine rebuild if the failure caused internal damage.

To reduce the risk:

– Use high-quality coolant: Subaru recommends specific coolant types; using the wrong kind can accelerate gasket wear.
– Avoid overheating: Never drive with a faulty thermostat or radiator fan.
– Monitor coolant levels: Top off as needed and investigate any sudden drops.

While not every 2013 Forester will have this issue, the high failure rate makes it one of the riskier years to buy.

The 2016–2017 Subaru Forester: Suspension and Steering Complaints

The 2016 and 2017 Subaru Forester models are generally reliable, but they’ve been plagued by suspension and steering issues that can affect ride quality and safety.

Suspension Problems

Owners have reported clunking noises from the front suspension, especially over bumps or when turning. The most common culprits are worn strut mounts, control arm bushings, and sway bar links. These components can wear out prematurely, especially in areas with potholes or harsh winters.

In some cases, the front struts themselves have failed, leading to a bouncy or unstable ride. Subaru issued a technical service bulletin (TSB) for front strut noise in 2016–2017 models, but not all vehicles were repaired under warranty.

Steering Issues

Another common complaint is a loose or vague steering feel. Some drivers report that the steering wheel doesn’t return to center properly or that there’s excessive play. This can be due to worn steering rack mounts or a failing power steering pump.

In rare cases, the electronic power steering (EPS) system has malfunctioned, causing the steering to become stiff or unresponsive. Subaru has issued recalls for EPS issues in other models, but the 2016–2017 Forester hasn’t been widely affected—yet.

How to Address These Issues

If you’re considering a 2016 or 2017 Forester:

– Listen for noises: During a test drive, pay attention to clunking, squeaking, or knocking sounds.
– Check alignment: Poor alignment can accelerate suspension wear.
– Inspect bushings and mounts: A mechanic can check for cracks, tears, or looseness.
– Ask about repairs: See if the previous owner addressed any suspension or steering concerns.

While these issues aren’t as severe as engine failures, they can still cost hundreds to repair and affect the driving experience.

The 2020 Subaru Forester: Battery and Electrical Gremlins

The 2020 Subaru Forester continued the fifth-generation redesign, but it introduced new electrical problems that have frustrated many owners.

Battery Drain and Alternator Failures

One of the most common complaints is premature battery failure. Some 2020 Foresters have had dead batteries within the first year of ownership. In many cases, the alternator—the component that charges the battery while driving—has failed, leaving the vehicle unable to start.

Subaru issued a recall in 2021 for alternator issues in 2020–2021 models, but not all vehicles were covered. Owners have reported alternators failing as early as 15,000 miles.

Infotainment and Sensor Glitches

The 2020 model also suffers from the same infotainment bugs as the 2019 version, including frozen screens and unresponsive controls. Additionally, some owners have reported malfunctioning parking sensors, blind-spot monitoring, and rearview cameras.

These issues are often software-related and can sometimes be fixed with updates. However, dealerships may not always have the latest software or the time to perform updates.

What to Do If You Own or Are Buying a 2020 Forester

– Test the battery and alternator: Use a multimeter or have a mechanic check charging voltage.
– Update all software: Ensure the infotainment, EyeSight, and engine control modules are up to date.
– Check for recalls: Visit the NHTSA website and enter the VIN to see if any recalls apply.
– Consider an extended warranty: Electrical issues can be expensive to fix, so extra coverage may be worth it.

While the 2020 Forester is generally reliable, its electrical problems make it a less-than-ideal choice for buyers seeking trouble-free ownership.

How to Avoid Buying a Lemon: Tips for Forester Shoppers

Even in the worst years, some Subaru Foresters are well-maintained and problem-free. The key is knowing how to spot a good one and avoid the pitfalls.

Get a Pre-Purchase Inspection (PPI)

Always have a trusted mechanic inspect any used Forester before you buy. A PPI can uncover hidden issues like oil leaks, worn suspension parts, or transmission problems. It typically costs $100–$150 but can save you thousands.

Check the Vehicle History Report

Use services like Carfax or AutoCheck to review the vehicle’s history. Look for accidents, flood damage, odometer rollback, and service records. A clean history doesn’t guarantee reliability, but a red flag history is a major warning.

Research Common Issues for the Year

Before buying, search online forums like SubaruOutback.org or Reddit’s r/Subaru for complaints about the specific model year. Owner experiences can give you a realistic picture of what to expect.

Consider Certified Pre-Owned (CPO)

Subaru’s CPO program includes a 7-year/100,000-mile powertrain warranty, 152-point inspection, and roadside assistance. While CPO models cost more, the peace of mind is often worth it—especially for problematic years.

Test Drive Thoroughly

During the test drive, pay attention to:

– Engine noise and oil level
– Transmission smoothness
– Suspension and steering feel
– Infotainment responsiveness
– Warning lights on the dashboard

Take the car on highways, hills, and city streets to test all driving conditions.

Negotiate Based on Known Issues

If the Forester has a known problem—like oil consumption or suspension wear—use that as leverage to negotiate a lower price. You’ll likely need to budget for repairs anyway.

Conclusion: Making a Smart Forester Purchase

The Subaru Forester is a solid SUV with a lot to offer, but not every model year is created equal. The 2014–2015 models suffer from excessive oil consumption, the 2019 model has CVT and EyeSight glitches, the 2013 model is prone to head gasket failures, the 2016–2017 models have suspension and steering complaints, and the 2020 model faces battery and electrical issues.

That doesn’t mean you should avoid the Forester altogether—just be smart about which year you choose. Avoid the worst years unless you’re prepared for potential repairs, or opt for a well-maintained example with a strong service history.

Always get a pre-purchase inspection, check the vehicle history, and consider a certified pre-owned model for added protection. With the right knowledge and precautions, you can find a Forester that’s reliable, safe, and fun to drive for years to come.
