Why Model Year Matters When Buying a Used Subaru Forester

Subaru has made significant improvements to the Forester over the years, especially in terms of safety, fuel efficiency, and technology. However, these advancements haven’t always been seamless. Some model years introduced new engines, transmissions, or electronics that came with unforeseen problems. Others inherited long-standing issues that Subaru was slow to address.

For example, the switch to a more fuel-efficient boxer engine in the mid-2010s brought better gas mileage but also increased reports of oil consumption. Similarly, the adoption of a continuously variable transmission (CVT) improved smoothness and efficiency but introduced new reliability concerns. Understanding these generational changes helps explain why certain years are riskier than others.

Additionally, Subaru’s popularity means that many used Foresters have high mileage or have been driven in harsh conditions—like snowy winters or off-road trails. Without proper maintenance, even a well-designed model can develop serious issues. That’s why knowing the weak spots of specific years can save you thousands in repairs and countless headaches down the road.

How We Determined the Worst Years

To identify the worst years for Subaru Forester, we analyzed data from multiple trusted sources, including the National Highway Traffic Safety Administration (NHTSA), Consumer Reports, J.D. Power, and real owner reviews from forums like SubaruOutback.org and Reddit’s r/Subaru. We also reviewed recall histories, technical service bulletins (TSBs), and common repair trends reported by mechanics.

Our criteria included:

• Frequency and severity of reported problems
• Number of official recalls and safety investigations
• Owner satisfaction ratings and complaint volume
• Cost and complexity of common repairs
• Long-term reliability trends

While no car is perfect, the years highlighted in this article stand out for consistently poor performance in one or more of these areas. Keep in mind that individual experiences can vary—some owners may have flawless Foresters from these years—but the patterns are too strong to ignore.

2014–2015 Subaru Forester: The Oil Consumption Nightmare

The 2014 and 2015 Subaru Forester models are often cited as some of the worst in the lineup, primarily due to a widespread issue with excessive oil consumption. These models came equipped with the 2.5-liter FB25 four-cylinder engine, which was designed to be more efficient and cleaner than its predecessor. Unfortunately, it also had a tendency to burn oil at an alarming rate.

Owners reported losing up to one quart of oil every 1,000 miles—far beyond the acceptable range. In some cases, drivers didn’t notice the problem until the engine started knocking or the “low oil” light came on. By then, internal damage like scored cylinder walls or worn piston rings could already be present. Subaru eventually acknowledged the issue and extended the powertrain warranty to 8 years or 100,000 miles for affected vehicles, but only if owners could prove they had been diligent about oil level checks.

Why Did This Happen?

The root cause was traced to the engine’s piston ring design. The rings didn’t seal properly under certain driving conditions, allowing oil to seep into the combustion chamber and burn off. This was especially common in vehicles that did a lot of short trips or city driving, where the engine didn’t reach optimal operating temperature consistently.

Subaru attempted to fix the issue with a software update and revised piston rings in later production runs, but many 2014 and early 2015 models still suffer from the problem. If you’re considering one of these years, it’s essential to check the oil level frequently and review the vehicle’s maintenance records. Look for evidence of oil top-offs or repairs related to oil consumption.

What Owners Are Saying

On Subaru forums, stories abound of Forester owners who had to add oil every few weeks. One user on SubaruOutback.org wrote, “I bought my 2014 Forester with 30,000 miles and within six months, I was adding a quart every 800 miles. Subaru replaced the engine under warranty, but it was a huge hassle.” Another owner reported engine failure at 90,000 miles due to oil starvation, despite regular oil changes.

While Subaru did issue a goodwill repair program for some vehicles, not all owners qualified. Those who didn’t keep meticulous records or missed the warranty window were left footing the bill for engine repairs that could cost $5,000 or more.

2013 Subaru Forester: Head Gasket Woes Return

The 2013 Subaru Forester may look like a solid choice on paper—good fuel economy, standard AWD, and a comfortable ride—but it carries a notorious legacy: head gasket failure. This issue plagued many Subaru models from the late 1990s through the early 2010s, and the 2013 Forester wasn’t spared.

The problem stems from the use of multi-layer steel (MLS) head gaskets, which were supposed to be more durable than the older composite gaskets. However, in practice, they still failed under stress, especially in vehicles that experienced overheating or were driven in hot climates. Symptoms include white smoke from the exhaust, coolant loss, overheating, and a sweet smell inside the cabin.

Why Head Gaskets Fail

Head gasket failure occurs when the seal between the engine block and cylinder head breaks down. This allows coolant to leak into the combustion chamber or oil passages, leading to engine damage. In the 2013 Forester, the issue was often linked to poor coolant circulation, thermostat problems, or prolonged towing—all of which increase engine temperature.

Unlike the oil consumption issue in later models, head gasket failure is typically a one-time catastrophic event. Once it happens, the repair is expensive, often costing between $1,500 and $2,500 depending on labor rates. In some cases, the engine may need to be replaced entirely.

Prevention and Detection

If you’re looking at a 2013 Forester, inspect the coolant reservoir for signs of oil contamination (a milky appearance) and check the oil dipstick for coolant (a frothy, chocolate-milk-like substance). Also, ask for maintenance records showing regular coolant changes and thermostat replacements.

Some owners have reported success with aftermarket head gasket kits or upgraded coolant systems, but these are not guaranteed fixes. Given the high cost of repair and the frequency of the issue, many experts recommend avoiding the 2013 model unless it has a documented history of proper maintenance and no signs of gasket problems.

2019 Subaru Forester: CVT Transmission Troubles

The 2019 Subaru Forester marked a major redesign, introducing a new platform, updated styling, and the latest EyeSight safety suite. It was also the first year to feature the FB25D engine and a revised Lineartronic CVT. While the new model was praised for its safety and technology, it quickly gained a reputation for CVT-related issues.

Owners reported a range of problems, including jerking during acceleration, hesitation when shifting, and a “rubber band” feeling under load. In colder climates, the transmission was especially problematic, with some drivers experiencing delayed engagement or complete failure to move after starting the vehicle.

What’s Causing the CVT Problems?

The Lineartronic CVT in the 2019 Forester uses a chain-driven design that’s generally reliable, but early production units had software and calibration issues. Subaru issued several technical service bulletins (TSBs) to address shift logic and cold-weather performance, but not all vehicles received the updates.

Additionally, the CVT fluid used in these models has a specific formulation that degrades faster than expected, especially if not changed regularly. Subaru recommends changing the CVT fluid every 60,000 miles, but many owners neglect this service, leading to premature wear.

Real-World Impact

On Reddit and other forums, 2019 Forester owners share stories of transmission replacements under warranty. One user wrote, “My CVT started jerking at 25,000 miles. Subaru replaced it, but the new one had the same issue. It’s been in the shop three times.” Another reported a complete transmission failure at 40,000 miles, leaving the vehicle undriveable.

While Subaru has extended the powertrain warranty to 8 years or 100,000 miles for some 2019 models, the process of getting repairs can be time-consuming and frustrating. If you’re considering a 2019 Forester, verify that all TSBs have been applied and that the CVT fluid has been changed on schedule.

2020 Subaru Forester: Infotainment System Glitches

The 2020 Subaru Forester continued the redesign momentum with minor updates and improved fuel economy. Mechanically, it was solid—but the Starlink infotainment system became a major pain point for many owners. The 8-inch touchscreen, while modern and feature-rich, was prone to freezing, crashing, and losing connectivity.

Common issues included the screen going black, Bluetooth failing to pair, navigation maps not loading, and the system rebooting randomly while driving. Some owners reported that the problem worsened over time, with the system becoming slower and less responsive.

Software Over Hardware

Unlike mechanical failures, infotainment problems are often software-related. Subaru released multiple over-the-air (OTA) updates to fix bugs, but not all vehicles received them automatically. Dealership visits were often required to install the latest firmware.

In some cases, the issue was traced to a faulty head unit that needed replacement. Subaru extended the warranty on the infotainment system for certain 2020 models, but coverage varied by region and dealership.

Owner Frustration

While not a safety issue, the infotainment problems were a major source of dissatisfaction. One owner on a Subaru forum said, “I love my Forester, but the screen freezes every time I use Apple CarPlay. It’s embarrassing when I’m showing it to friends.” Another reported having the system replaced twice under warranty.

If you’re looking at a 2020 Forester, test the infotainment system thoroughly during your test drive. Check for software updates and ask the dealer if any recalls or TSBs apply to the head unit.

2016–2017 Subaru Forester: Suspension and Steering Concerns

The 2016 and 2017 Subaru Forester models are generally reliable, but they’ve developed a reputation for premature wear in suspension and steering components. Owners report issues with struts, ball joints, and power steering racks failing well before the expected lifespan.

The problem is often linked to the vehicle’s design and driving dynamics. The Forester’s high center of gravity and all-wheel-drive system place extra stress on suspension parts, especially when driven aggressively or on rough roads. In snowy regions, road salt accelerates corrosion, leading to faster deterioration.

Common Failure Points

Front struts may wear out by 60,000–80,000 miles, causing a bouncy ride and poor handling. Ball joints can fail as early as 50,000 miles, leading to clunking noises and alignment issues. The electric power steering (EPS) system has also been known to develop faults, with some owners experiencing sudden loss of assist.

These repairs can be costly—strut replacement runs $600–$800 per side, while ball joint service can exceed $400. EPS repairs may require a new steering rack, costing over $1,500.

Prevention Tips

Regular inspections and maintenance can help catch these issues early. Have a mechanic check suspension components during oil changes, especially if you drive on rough roads or in harsh climates. Consider upgrading to aftermarket parts with better corrosion resistance if you live in a snowy area.

Early 2000s Foresters (2000–2005): Rust and Reliability Issues

While not the newest, the early 2000s Subaru Forester models (2000–2005) are still on the road and can be tempting for budget buyers. However, these vehicles are notorious for rust problems, particularly in the frame, wheel wells, and underbody.

In regions with heavy snow and road salt use, corrosion can compromise structural integrity and lead to safety concerns. The 2003 and 2004 models were especially affected, with some vehicles failing state inspections due to rust damage.

Additionally, these older Foresters used the EJ25 engine, which is durable but prone to head gasket failures and oil leaks if not maintained. Timing belt replacements are critical—every 60,000–100,000 miles—and neglecting this service can result in catastrophic engine failure.

Should You Buy One?

If you’re considering an early 2000s Forester, inspect it thoroughly for rust, especially around the rear wheel arches and frame rails. Check maintenance records for timing belt and head gasket service. These models can be reliable if well cared for, but they require more attention than newer Foresters.

How to Avoid Buying a Lemon: Tips for Forester Shoppers

Even in the worst years, a well-maintained Subaru Forester can be a great buy. Here are some tips to help you avoid common pitfalls:

• Get a pre-purchase inspection: Have a trusted mechanic inspect the vehicle, especially the engine, transmission, and suspension.
• Check the vehicle history report: Use services like Carfax or AutoCheck to look for accidents, flood damage, and service records.
• Review recall and TSB history: Visit the NHTSA website to see if the vehicle has any open recalls or technical service bulletins.
