Introduction: Why the Subaru Forester Is Popular—and When to Be Cautious

The Subaru Forester has earned a loyal following over the years. It’s a compact SUV that blends practicality, all-wheel drive capability, and a reputation for durability. Whether you’re navigating snowy mountain roads or hauling gear for a weekend camping trip, the Forester has long been a go-to choice for outdoor enthusiasts and families alike. Its standard AWD, spacious interior, and strong safety ratings make it a standout in its class.

But like any vehicle, not every model year is created equal. While Subaru has made significant improvements over the decades, certain Forester generations have been plagued by recurring mechanical issues. From oil-guzzling engines to finicky transmissions, some years are best avoided—especially if you’re buying used. Knowing which Subaru Forester years to avoid can save you from unexpected breakdowns, hefty repair bills, and endless frustration.

Understanding Subaru Forester Generations and Reliability Trends

Before diving into specific problematic years, it helps to understand the Forester’s generational evolution. Subaru introduced the Forester in 1997 as a rugged, wagon-like alternative to traditional SUVs. Over the years, it has evolved through four major generations, each with its own strengths and weaknesses.

The first generation (1998–2002) was basic but reliable, though early models had some suspension and rust issues. The second generation (2003–2008) brought more power and refinement but introduced the now-infamous head gasket problems. The third generation (2009–2013) improved on design and safety but continued to struggle with oil consumption and engine reliability. The fourth generation (2014–2018) marked a shift to more modern tech and a continuously variable transmission (CVT), which brought new challenges. The current fifth generation (2019–present) has seen major improvements in build quality, safety, and infotainment—though not without a few growing pains.

Reliability trends show that Subaru has made steady progress, especially after 2015. However, certain model years stand out as particularly troublesome. The key is knowing where the pitfalls lie—and how to spot a well-maintained example even in a risky year.

Subaru Forester Years to Avoid: 2011–2013 Models

If there’s one range of years that consistently tops the “avoid” list, it’s the 2011–2013 Subaru Forester. These models are infamous for two major issues: excessive oil consumption and premature head gasket failure.

Excessive Oil Consumption: The Silent Engine Killer

Owners of 2011–2013 Foresters often report burning through a quart of oil every 1,000 to 1,500 miles. This isn’t just a minor inconvenience—it’s a serious engine problem. Subaru eventually acknowledged the issue and extended the powertrain warranty to 8 years or 100,000 miles for affected vehicles, but many owners still faced out-of-pocket repairs.

The root cause? Poor piston ring design and inadequate cylinder wall machining in the 2.5L naturally aspirated engine. Over time, these flaws allow oil to slip into the combustion chamber, where it burns off instead of lubricating the engine. The result? Increased emissions, reduced performance, and potential engine damage if oil levels aren’t monitored closely.

For example, a 2012 Forester owner in Colorado reported adding a quart of oil every two weeks during winter months. Despite regular maintenance, the engine eventually developed a knock and required a full rebuild at 90,000 miles.

Head Gasket Failures: A Costly and Common Problem

Head gasket issues aren’t new to Subaru, but the 2011–2013 Foresters brought them back with a vengeance. The head gasket seals the engine block and cylinder head, preventing coolant and oil from mixing. When it fails, you’ll notice white smoke from the exhaust, coolant loss, overheating, and a sweet smell inside the cabin.

Replacing a head gasket is no small job—it typically costs between $1,500 and $2,500, including labor. In severe cases, the engine may warp or crack, requiring even more extensive repairs.

Subaru attempted to address the issue with redesigned gaskets and improved coolant systems, but many owners still experienced failures well before 100,000 miles. If you’re considering a 2011–2013 Forester, ask for maintenance records and check for signs of coolant leaks or oil contamination.

2014–2015 Subaru Forester: CVT Transmission Concerns

The 2014–2015 Subaru Forester marked a major shift for the brand. It introduced a new platform, updated styling, and—most notably—a continuously variable transmission (CVT) as standard equipment. While the CVT improved fuel economy and smoothness in theory, it also introduced new reliability concerns.

CVT Hesitation and Jerking: A Driving Nightmare

Many 2014–2015 Forester owners report a “jerking” or “surging” sensation during acceleration, especially from a stop or at low speeds. This is often described as feeling like the transmission is slipping or momentarily losing power. In some cases, the vehicle may hesitate before lurching forward, creating a dangerous situation in traffic.

The issue is linked to the CVT’s control software and torque converter design. Subaru released several technical service bulletins (TSBs) and software updates to address the problem, but not all vehicles were repaired under warranty. Owners who didn’t visit a dealer for updates may still experience symptoms.

For instance, a 2015 Forester owner in Oregon reported the transmission jerking so severely that it stalled at a red light. After multiple visits to the dealership, the issue was only partially resolved with a software patch.

Premature CVT Failure: When the Transmission Gives Out

In more severe cases, the CVT can fail entirely—often before 100,000 miles. Symptoms include whining noises, loss of power, and the dreaded “limp mode” that restricts the vehicle to low speeds. Replacing a CVT can cost upwards of $4,000, making it one of the most expensive repairs on a used Forester.

While not all 2014–2015 models suffer from CVT failure, the risk is high enough to warrant caution. If you’re considering one of these years, ask whether the transmission has been serviced and whether any software updates were applied. A pre-purchase inspection by a Subaru specialist is highly recommended.

2006–2009 Subaru Forester: The Head Gasket Era

Long before the 2011–2013 oil consumption crisis, Subaru was battling head gasket issues in the mid-2000s. The 2006–2009 Forester models, part of the second generation, are particularly notorious for this problem.

Why Head Gaskets Fail in These Models

The 2.5L engine used in these Foresters was prone to overheating, especially in hot climates or under heavy load. Subaru’s original head gasket design used a multi-layer steel (MLS) gasket that, while durable, could fail if the engine overheated even once. Once the gasket failed, coolant would leak into the combustion chamber or oil passages, leading to white smoke, overheating, and engine damage.

Many owners didn’t realize there was a problem until it was too late. A common story involves a driver noticing the temperature gauge creeping up during a long drive, only to find coolant puddling under the car upon arrival.

Subaru’s Response and Extended Warranty

Subaru eventually acknowledged the issue and extended the head gasket warranty to 8 years or 100,000 miles for 2006–2009 models. They also redesigned the gasket and improved the cooling system in later years. However, vehicles outside the warranty period—or those with incomplete service records—remain at risk.

If you’re looking at a 2006–2009 Forester, check for signs of coolant loss, milky oil (indicating coolant mixing), or white exhaust smoke. Ask if the head gasket has ever been replaced—and if so, whether it was done with the improved design.

2019–2020 Subaru Forester: Infotainment and Software Glitches

The 2019–2020 Subaru Forester represents the start of the fifth generation—a major redesign that brought a new platform, improved safety features, and a modern infotainment system. Mechanically, these models are among the most reliable in Forester history. However, they’re not without their quirks.

Starlink Infotainment System Issues

The 2019–2020 Forester comes standard with Subaru’s Starlink infotainment system, featuring an 8-inch touchscreen, Apple CarPlay, Android Auto, and navigation. While the system is feature-rich, many owners report software glitches, including:

– Touchscreen freezing or becoming unresponsive
– Apps crashing or failing to load
– Bluetooth connectivity issues
– Delayed response to inputs

These problems are often intermittent and may resolve after a system reboot, but they can be frustrating—especially when you’re trying to use navigation or hands-free calling.

Subaru has released several software updates to address these issues, but not all vehicles have received them. If you’re considering a 2019–2020 model, ask the dealer or previous owner if the system has been updated to the latest version.

Safety System False Alarms

Another common complaint involves the EyeSight driver-assistance system, which includes adaptive cruise control, lane departure warning, and pre-collision braking. Some owners report false alarms—such as the car braking suddenly for no reason or the lane departure system activating on straight roads.

These issues are often caused by dirty or misaligned cameras, but they can also stem from software bugs. Again, software updates have helped, but not eliminated, the problem.

Despite these tech hiccups, the 2019–2020 Forester is still a solid choice—especially if you prioritize safety and modern features. Just be prepared for occasional glitches and keep the system updated.

How to Avoid Buying a Problematic Subaru Forester

Even if you’re eyeing a model year known for issues, there are ways to reduce your risk and find a reliable example.

Check the Vehicle History Report

Always run a vehicle history report using services like Carfax or AutoCheck. Look for:

– Accident history
– Number of previous owners
– Service and repair records
– Title status (avoid salvage or flood-damaged vehicles)

A clean report doesn’t guarantee reliability, but it’s a good starting point.

Inspect Maintenance Records

A well-maintained Forester—even from a problematic year—can be a great buy. Look for:

– Regular oil changes (every 5,000–7,500 miles)
– Coolant flushes (every 30,000–60,000 miles)
– Timing belt replacements (if applicable, every 60,000–100,000 miles)
– Evidence of head gasket or CVT repairs

If the owner can’t provide records, assume the worst.

Get a Pre-Purchase Inspection

This is non-negotiable. Have a trusted mechanic—preferably one familiar with Subarus—inspect the vehicle before you buy. They can check for:

– Oil consumption (measure dipstick level over a few days)
– Coolant leaks or contamination
– Transmission fluid condition and CVT operation
– Suspension and brake wear

A $100–$150 inspection can save you thousands in repairs.

Test Drive Thoroughly

During the test drive, pay attention to:

– Engine smoothness and oil level
– Transmission behavior (especially during acceleration)
– Infotainment responsiveness
– Unusual noises (whining, knocking, grinding)

If anything feels off, walk away.

Conclusion: Making a Smart Choice with the Subaru Forester

The Subaru Forester is a fantastic vehicle—when you pick the right year. While models from 2011–2013, 2006–2009, and 2014–2015 come with known risks, that doesn’t mean every example is a lemon. With careful research, thorough inspections, and attention to maintenance history, you can find a reliable Forester that will serve you well for years.

The key is to avoid the Subaru Forester years with the highest failure rates and focus on well-cared-for examples—or consider newer models (2021 and later) that benefit from Subaru’s improved engineering and quality control.

Ultimately, knowledge is your best defense. By understanding which Subaru Forester years to avoid and what to look for in a good used model, you can drive away with confidence—and maybe even enjoy a few off-road adventures along the way.
