The Subaru Forester launched in the U.S. in 1997 as a compact SUV that combined ruggedness with everyday practicality. Its all-wheel drive system, reliability, and safety features made it a favorite among American drivers. Over the years, the Forester solidified its reputation as a dependable crossover, ideal for families, adventurers, and commuters alike. However, not all model years are created equal. Some have been plagued by serious issues, leading to costly repairs and owner dissatisfaction. We’ll cover seven Subaru Forester years to avoid due to significant reliability problems, subpar performance, or frustrating maintenance issues. Here’s what you need to know before making a purchase.

2001 Subaru Forester

The 2001 Forester is infamous for head gasket failures, a common issue with Subaru’s older Boxer engines. This defect leads to coolant leaks, overheating, and potential engine damage. While Subaru later addressed this problem, owners of early models often found themselves facing repair bills of over $1,500.

Additionally, transmission slippage was a frequent complaint. Drivers reported difficulty shifting and sudden power loss during acceleration, which compromised safety. Rust issues on the undercarriage and suspension components further diminished the model’s longevity. Considering these chronic issues, the 2001 Forester is best avoided unless extensively repaired and inspected.

2003 Subaru Forester

The 2003 Forester suffered from transmission and drivetrain problems, particularly with the automatic models. Owners reported hesitation during gear shifts, a problem that worsened over time. Electrical system failures, including faulty sensors and battery drain, were also common.

Rust-prone components added to the list of concerns. Premature rusting on the rear subframe was particularly problematic, as it could compromise the vehicle’s structural integrity. This model also lacked the refined suspension and noise insulation seen in later years, making it less comfortable for long trips. The 2003 Forester has a long history of complaints, making it a risky choice for buyers seeking reliability.

2006 Subaru Forester

The 2006 Forester, particularly the turbocharged XT model, faced catastrophic engine issues due to oil starvation. The turbochargers frequently failed because of inadequate lubrication, which required costly replacements often exceeding $4,000.

Non-turbo models didn’t fare much better, with widespread suspension and wheel bearing issues. Many drivers also noted that the vehicle’s paintwork and exterior trim were prone to premature fading and chipping. These problems collectively detract from the Forester’s otherwise durable reputation during this era​.​

2012 Subaru Forester

The 2012 Forester was affected by a class-action lawsuit over excessive oil consumption in its FB25 engine. Many owners reported that their engines burned oil at an alarming rate, forcing them to add oil between changes. Subaru eventually extended warranties for affected vehicles, but the inconvenience and long-term engine wear left many drivers frustrated.

In addition to oil issues, some 2012 Foresters experienced suspension noise and uneven tire wear, likely due to misaligned components from the factory. These issues compromised ride comfort and led to higher maintenance costs. Despite Subaru’s efforts to mitigate the problems, the 2012 Forester remains one of the least reliable years.​

2014 Subaru Forester

The 2014 Forester introduced Subaru’s continuously variable transmission (CVT) to the model lineup, but it wasn’t without growing pains. Owners frequently complained of jerky acceleration, delayed response, and outright CVT failure. These transmission problems led to expensive repairs, often exceeding $3,000.

Another widespread issue was windshield cracking due to residual stress in the glass. This defect, which affected many Subaru models, led to a class-action lawsuit. While Subaru offered an extended warranty for windshield replacements, owners often found themselves dealing with recurring issues. These combined flaws make the 2014 one of our Subaru Forester years to avoid.

2018 Subaru Forester

The 2018 Forester suffered from a mix of electronic and mechanical issues. Subaru’s Starlink infotainment system, included in many trims, frequently malfunctioned, causing connectivity problems with navigation and Bluetooth devices. For tech-savvy drivers, these issues were a major annoyance.

On the mechanical side, some 2018 Foresters experienced premature battery failure, which left drivers stranded unexpectedly. Timing chain problems were also reported, and repairs for these components can exceed $2,000. While newer than many on this list, the 2018 model year disappointed in terms of reliability and owner satisfaction​.​

2020 Subaru Forester

The 2020 Forester faced complaints about its CVT, a common issue across many Subaru models. Drivers reported delayed throttle response and sudden surges in power, which created unpredictable driving dynamics. Such problems, particularly during highway merging, posed serious safety risks.

Additionally, the EyeSight driver-assistance system occasionally malfunctioned, leading to false braking or collision alerts. Although the technology was intended to enhance safety, these glitches reduced trust in the system. Combined with the ongoing CVT concerns, the 2020 Forester falls short of expectations for a newer model​.

While the Subaru Forester is generally a reliable and well-loved compact SUV, these specific years left many drivers disappointed due to persistent mechanical and structural problems. If you’re shopping for a used Forester, it’s crucial to research specific model years and inspect the vehicle thoroughly before purchase.

For better reliability, consider model years like 2013 or 2017, which have fewer reported issues. When in doubt, consult trusted sources like CarComplaints.com, J.D. Power, or the NHTSA for detailed reliability and safety ratings. By avoiding problematic years, you can enjoy the Subaru Forester’s versatility and dependability without costly headaches down the road.
