Why Model Year Matters When Buying a Used Subaru Forester

When shopping for a used car, the model year is one of the most important factors to consider—especially with Subarus. Unlike some brands that make minor cosmetic updates each year, Subaru often introduces significant mechanical changes between generations. These changes can include new engines, transmissions, suspension setups, and electronics. While innovation is great, it sometimes leads to teething problems in early production runs.

For example, the switch from the FB-series engine to the newer FA24 engine in 2019 brought improved power and efficiency—but also new software and hardware challenges. Similarly, the introduction of the Continuously Variable Transmission (CVT) in the early 2010s replaced the traditional automatic, offering better fuel economy but introducing new failure points.

Another reason model year matters is wear and tear patterns. Certain issues, like head gasket failures or oil consumption, tend to show up after 80,000 to 100,000 miles. If a vehicle is already past that threshold, even a well-maintained Forester could be nearing the end of its reliable lifespan. That’s why knowing which years are prone to early failures is crucial.

Finally, consumer reports, repair data, and owner forums consistently highlight trends across specific model years. These real-world insights are invaluable. For instance, if hundreds of 2014 Forester owners report the same transmission shudder at 60,000 miles, that’s a red flag no amount of marketing can hide.

The Most Problematic Years: 2014–2015 Subaru Forester

If there’s one range of years you should approach with extreme caution, it’s the 2014 and 2015 Subaru Forester models. These vehicles were part of the third generation (SH series) and introduced the FB25 2.5-liter four-cylinder engine paired with a CVT transmission. While the new engine was more efficient and smoother than its predecessor, it came with a host of reliability concerns that have plagued owners for years.

Excessive Oil Consumption

One of the most widespread issues with the 2014–2015 Forester is excessive oil consumption. Many owners reported burning through a quart of oil every 1,000 to 1,500 miles—far beyond what’s considered normal. Subaru initially downplayed the issue, but eventually issued Technical Service Bulletins (TSBs) acknowledging the problem. In some cases, the engine would consume so much oil that it could lead to low oil pressure, engine damage, or even complete failure if not monitored closely.

This wasn’t just a minor inconvenience. Imagine driving cross-country and having to stop every few hundred miles to top off your oil. Worse, if you forget or don’t check regularly, you risk catastrophic engine damage. Some owners even reported oil levels dropping below the minimum mark between scheduled oil changes.

CVT Transmission Problems

The Continuously Variable Transmission (CVT) in these models also drew criticism. While CVTs are designed to improve fuel efficiency by providing seamless acceleration, the early versions in the Forester were prone to shuddering, jerking, and delayed response. Many drivers described a “rubber band” effect when accelerating from a stop, where the engine revs high but the car doesn’t move proportionally.

Additionally, CVTs are more complex and expensive to repair than traditional automatics. A full replacement can cost $4,000 or more, and extended warranties often exclude wear-and-tear items. Some owners reported transmission failures as early as 70,000 miles, especially in vehicles driven in hot climates or used for towing.

Head Gasket Failures (Again)

Subaru has a long history with head gasket issues, and the 2014–2015 Forester didn’t escape this legacy. While the FB-series engines were supposed to be more reliable than the older EJ engines, many still experienced head gasket leaks—especially in vehicles with high mileage or poor maintenance history. Symptoms include coolant loss, overheating, white smoke from the exhaust, and a sweet smell inside the cabin.

Replacing a head gasket on a Subaru is no small job. It requires removing the engine or lifting it significantly, making it one of the most labor-intensive repairs on the vehicle. Costs typically range from $1,500 to $3,000, depending on labor rates and whether additional damage occurred.

Electrical and Infotainment Glitches

Beyond mechanical issues, the 2014–2015 models also suffered from electrical quirks. The Starlink infotainment system, while advanced for its time, was prone to freezing, rebooting, or losing connectivity. Some owners reported the screen going black while driving, requiring a hard reset. Others experienced issues with the backup camera, Bluetooth pairing, or navigation system.

These problems weren’t safety-critical, but they were frustrating and often required dealership visits for software updates or module replacements. In some cases, the issues persisted even after multiple repairs.

Should You Avoid 2014–2015 Models Entirely?

Not necessarily—but you must be extremely cautious. If you find a well-maintained 2014 or 2015 Forester with full service records, low mileage, and no signs of oil consumption or transmission issues, it could still be a decent buy. However, you should expect to monitor oil levels weekly and budget for potential repairs.

A pre-purchase inspection by a trusted mechanic is non-negotiable. Ask specifically about oil consumption tests, CVT fluid condition, and head gasket integrity. Also, check the vehicle’s history report for previous repairs or complaints.

2016–2018 Subaru Forester: Moderate Risk with Lingering Issues

The 2016–2018 Subaru Forester models represent a slight improvement over the earlier years, but they’re not without their own set of concerns. These vehicles continued using the FB25 engine and CVT transmission, but Subaru made incremental updates to address some of the previous problems. Still, several issues persist, especially as these vehicles age and accumulate mileage.

Continued Head Gasket Concerns

While Subaru claimed to have improved the head gasket design in later FB engines, failures still occur—particularly in high-mileage examples. The problem tends to show up after 100,000 miles, especially in vehicles that haven’t had regular coolant changes or have been driven in extreme temperatures.

One owner on a popular Subaru forum shared that their 2017 Forester started overheating during a summer road trip. A mechanic found a blown head gasket and estimated a $2,800 repair. “I loved the car,” they wrote, “but I didn’t love paying more than the car was worth to fix it.”

CVT Reliability Remains a Concern

The CVT in these models is more refined than in the 2014–2015 versions, but it’s still not immune to failure. Shuddering during acceleration, delayed shifts, and whining noises are common complaints. Some owners report that the transmission feels “slippery” or unresponsive, especially when climbing hills or merging onto highways.

Subaru extended the CVT warranty to 10 years or 100,000 miles on some models, but this doesn’t cover all repairs—and many vehicles are now outside that window. If you’re buying a used 2016–2018 Forester, ask about the CVT fluid change history. Subaru recommends changing it every 30,000 to 60,000 miles, but many owners skip this service.

Suspension and Steering Complaints

Another area of concern is the suspension and steering systems. Some owners report clunking noises from the front end, especially over bumps or during turns. This is often linked to worn struts, control arm bushings, or sway bar links. While these aren’t catastrophic failures, they can affect ride quality and safety if left unaddressed.

Power steering issues have also been reported, particularly in colder climates. Some drivers notice a delay or stiffness when turning the wheel, which can be alarming in emergency situations.

Infotainment and Software Bugs

The Starlink system in these models is more stable than in earlier years, but it’s not perfect. Glitches like slow response times, unresponsive touchscreens, and Bluetooth disconnections still occur. Subaru has released multiple software updates over the years, so it’s important to ensure the vehicle’s system is up to date.

Is the 2016–2018 Forester a Safe Buy?

These models are a step up from the 2014–2015 versions, but they’re still considered moderate-risk purchases. If you find one with low mileage, a clean history, and documented maintenance—especially CVT fluid changes and coolant flushes—it could be a solid choice. However, budget for potential repairs and consider an extended warranty if available.

2019–2021 Subaru Forester: New Platform, New Problems

With the 2019 model year, Subaru introduced the fifth-generation Forester on the new Subaru Global Platform (SGP). This was a major redesign, featuring a stiffer chassis, improved safety features, and a new 2.5-liter FA24 engine. While these changes brought many benefits, the early years of this generation came with their own set of teething issues.

Infotainment and Electrical Glitches

The 2019–2021 Foresters feature a larger, more advanced infotainment system with Apple CarPlay and Android Auto. However, early adopters reported frequent software bugs. Common issues include screen freezes, random reboots, and connectivity problems with smartphones.

One owner described how their 2020 Forester’s screen would go black during drives, only to restart after a few minutes. “It’s scary when you’re on the highway and your backup camera disappears,” they said. Subaru has issued several software updates to address these issues, so it’s important to verify that the vehicle has the latest firmware.

Engine Misfires and Rough Idling

Some 2019–2021 models have experienced engine misfires, particularly in cold weather. The FA24 engine is generally reliable, but a small number of vehicles have had issues with ignition coils or fuel injectors. Symptoms include rough idling, hesitation during acceleration, and check engine lights.

In most cases, replacing the faulty component resolves the issue. However, diagnosing the problem can be time-consuming and costly if not covered under warranty.

Wind Noise and Build Quality Complaints

Early 2019 models were criticized for excessive wind noise at highway speeds. Owners reported whistling or howling sounds around the A-pillars or side mirrors. Subaru later issued revised weatherstripping and sealing components to reduce noise, but some vehicles still exhibit the issue.

Additionally, a few owners have noted inconsistent panel gaps or rattles in the interior, suggesting variability in build quality during the initial production run.

Are 2019–2021 Foresters Worth Considering?

Despite these issues, the 2019–2021 Forester is a significant improvement over earlier generations. The new platform offers better ride quality, safety, and fuel efficiency. Most of the reported problems are minor and often resolved with software updates or minor repairs.

If you’re looking at one of these models, prioritize vehicles with updated software and a clean maintenance history. Test drive it on the highway to check for wind noise and ensure all electronics function properly.
