Why Some Subaru Forester Years Are Problematic

Every car model has its ups and downs, and the Subaru Forester is no exception. While Subaru has consistently delivered dependable SUVs, certain model years have been plagued by design flaws, manufacturing oversights, or rushed updates that led to widespread issues. These problems often stem from engine quirks, transmission weaknesses, or electrical system bugs that weren’t fully resolved until later model years.

One of the biggest factors influencing reliability is the timing of major redesigns. Subaru introduced a completely new platform for the Forester in 2014, which brought modern styling, improved fuel efficiency, and updated safety features. However, this transition also introduced new challenges. The 2014 and 2015 models, in particular, suffered from engine-related problems that were not present in earlier generations. Similarly, the shift to a continuously variable transmission (CVT) in many models starting in 2014 brought fuel economy gains but also new reliability concerns.

Another key issue is how quickly Subaru rolled out software updates and recalls. In some cases, problems were identified early, but fixes weren’t widely implemented until after many vehicles had already been sold. This means that even if a recall exists, not all owners may have had their cars repaired—especially if they bought used or didn’t stay on top of service notifications.

Additionally, driving conditions and maintenance habits play a huge role. A Forester driven primarily in cold climates may face different wear patterns than one used in milder regions. For example, engines prone to oil consumption may struggle more in winter, while CVT transmissions can overheat in stop-and-go traffic or during towing.

Understanding these factors helps explain why some years are best avoided. It’s not that every Forester from those years will fail—many still run perfectly fine—but the risk is significantly higher. By steering clear of the most problematic years, you increase your chances of getting a dependable, long-lasting vehicle.

2014–2015 Subaru Forester: The Oil Consumption Nightmare

The 2014 and 2015 Subaru Forester models marked a major redesign for the popular compact SUV. With a sleeker look, improved interior materials, and advanced safety tech like EyeSight (on higher trims), these models were a big step forward. Unfortunately, they also brought one of the most notorious issues in Forester history: excessive oil consumption.

The Root of the Problem

The issue primarily affected the 2.5-liter naturally aspirated four-cylinder engine (the FB25). Many owners reported burning through a quart of oil every 1,000 to 1,500 miles—far beyond the acceptable range. Subaru initially downplayed the problem, but as complaints piled up, the company acknowledged it and issued technical service bulletins (TSBs) and, eventually, a class-action lawsuit settlement.

The root cause was traced to piston ring design. The rings didn’t seal properly under certain conditions, allowing oil to seep into the combustion chamber and burn off. This wasn’t just an inconvenience—it could lead to low oil levels, reduced engine performance, and even catastrophic engine failure if ignored.

Real-World Impact

Imagine driving your Forester on a long road trip and suddenly noticing the oil light flicker. You pull over, check the dipstick, and find the oil level dangerously low. This scenario played out for thousands of owners. Some reported needing oil top-offs every few weeks, while others faced engine damage that required costly rebuilds or replacements.

One owner in Colorado shared that her 2015 Forester consumed two quarts of oil in just 800 miles. She had to keep a spare quart in the trunk at all times. Another driver in Minnesota experienced engine knocking and loss of power, eventually discovering metal shavings in the oil—a sign of internal engine wear.

Subaru’s Response

Subaru eventually offered a repair program for affected vehicles, including updated piston rings and improved engine software. However, the fix wasn’t always effective, and many owners reported continued oil consumption even after the repair. The class-action settlement provided compensation for some, but it didn’t erase the hassle and downtime.

What This Means for Buyers

If you’re considering a 2014 or 2015 Forester, proceed with extreme caution. Always check the maintenance records to see if the oil consumption issue was addressed. Ask the owner how often they top off oil and whether they’ve noticed any warning signs like blue smoke from the exhaust or a burning smell.

Even if the car has been repaired, monitor oil levels closely during your test drive and in the first few weeks of ownership. Consider having a mechanic perform a compression test to assess engine health. And remember: while some of these Foresters run fine, the risk is simply too high for many buyers.

2016–2017 Subaru Forester: CVT Transmission Troubles

The 2016 and 2017 Subaru Forester models continued the trend of modern updates, including refreshed styling, better fuel economy, and enhanced safety features. But beneath the surface, many of these vehicles were equipped with a continuously variable transmission (CVT) that proved less than reliable.

Understanding the CVT Issues

Subaru began phasing in CVTs across its lineup in the mid-2010s to improve fuel efficiency and meet stricter emissions standards. While CVTs can offer smoother acceleration and better gas mileage, they’re also more complex and prone to wear than traditional automatic transmissions.

In the 2016–2017 Forester, the CVT was known to exhibit several problems:
– Jerking or hesitation during acceleration
– Slipping under load, especially when climbing hills or towing
– Delayed engagement when shifting from park to drive
– Premature wear leading to transmission failure

These issues were often more pronounced in vehicles driven in hot climates or used for frequent stop-and-go driving. The transmission control module (TCM) software also played a role—some early versions didn’t manage gear ratios efficiently, causing stress on internal components.

Owner Experiences

Many owners reported that their Forester felt “sluggish” or “uncoordinated” during normal driving. One driver in Arizona said her 2016 Forester would hesitate for several seconds when merging onto the highway, creating a dangerous situation. Another in Texas experienced complete transmission failure at just 60,000 miles, requiring a $4,000 replacement.

Subaru issued multiple software updates to address shifting behavior, but these didn’t always resolve the underlying mechanical wear. In some cases, the transmission would fail shortly after the update, leaving owners frustrated and out of pocket.

Warranty and Repair Challenges

While Subaru’s powertrain warranty covered the CVT for 5 years or 60,000 miles, many owners found that repairs were delayed due to parts shortages or dealer reluctance to acknowledge the issue. Even when covered, the process could take weeks, leaving drivers without a vehicle.

Additionally, once the warranty expired, owners were on their own. Replacing a CVT can cost $3,500 to $5,000 or more, making it one of the most expensive repairs a Forester owner can face.

Tips for Buyers

If you’re looking at a 2016 or 2017 Forester, pay close attention to how the transmission behaves during your test drive. Accelerate firmly from a stop, merge onto a highway, and drive uphill if possible. Listen for unusual noises, feel for jerking or slipping, and note any delays in response.

Ask for service records to see if the TCM has been updated and whether any transmission-related repairs were performed. Check the vehicle’s history report for previous claims or complaints. And consider having a transmission specialist inspect the vehicle before purchase.

While some 2016–2017 Foresters have had trouble-free CVTs, the risk is high enough that many experts recommend avoiding these years unless you’re prepared for potential repairs.

2019 Subaru Forester: Power Steering and Infotainment Woes

The 2019 Subaru Forester introduced a complete redesign with a new platform, updated styling, and a host of new technology. It was praised for its spacious interior, excellent visibility, and strong safety ratings. However, early production models faced a couple of notable issues that buyers should be aware of.

Electric Power Steering (EPS) Failures

One of the most concerning problems in the 2019 Forester was sudden power steering failure. Drivers reported that the steering would become heavy or unresponsive, especially at low speeds or when parking. In some cases, the vehicle would display a warning light and enter “limp mode,” limiting speed and functionality.

The issue was traced to a faulty steering angle sensor or problems with the EPS control module. Subaru issued a recall (NHTSA Campaign Number: 19V-733) to address the problem, but not all vehicles were repaired immediately. Some owners didn’t receive notifications, and others delayed service due to busy schedules or lack of symptoms.

Infotainment System Glitches

The 2019 Forester also came with Subaru’s Starlink infotainment system, which offered Apple CarPlay, Android Auto, and navigation. While the features were welcome, the system was prone to freezing, crashing, or failing to recognize smartphones.

Many users reported that the screen would go black, reboot randomly, or lose connection to their phone mid-drive. Subaru released several software updates to improve stability, but some owners continued to experience problems even after updates.

Other Minor Issues

A few other complaints surfaced in early 2019 models, including:
– Wind noise at highway speeds due to door seal inconsistencies
– Rattling from the dashboard or rear cargo area
– Inconsistent performance from the automatic start-stop system

While these weren’t deal-breakers, they added to the overall perception of quality control issues in the first year of the new generation.

What to Watch For

If you’re considering a 2019 Forester, verify that the power steering recall has been completed. Ask for proof of repair or check the VIN on the NHTSA website. Test the infotainment system thoroughly—connect your phone, use navigation, and check for responsiveness.

Also, listen for unusual noises while driving and pay attention to how the steering feels, especially during tight turns or parking maneuvers. A quick test in a parking lot can reveal a lot.

2020 Subaru Forester: Electrical and Battery Drain Issues

The 2020 Subaru Forester built on the strengths of the 2019 model, with minor refinements and improved reliability. However, it wasn’t without its own set of challenges, particularly in the realm of electrical systems.

Battery Drain and Parasitic Draw

One of the most common complaints among 2020 Forester owners was unexpected battery drain. Vehicles would fail to start after sitting for a few days, even with a relatively new battery. In some cases, the battery would die overnight.

The root cause was often a parasitic draw—an electrical component that continued to draw power even when the car was off. Common culprits included the infotainment system, keyless entry module, or faulty wiring. Subaru issued service bulletins and software updates to address the issue, but not all vehicles were fixed promptly.

Software Bugs and System Glitches

The 2020 model also saw its share of software-related problems. Some owners reported that the EyeSight driver-assist system would malfunction, giving false warnings or failing to engage. Others experienced issues with the automatic headlights, wipers, or climate control.

These glitches were often resolved with over-the-air updates or dealer reprogramming, but they could be frustrating and potentially dangerous if safety systems were affected.

Other Reported Concerns

A small number of 2020 Foresters experienced:
– Premature wear on brake pads and rotors
– Water leaks around the sunroof or windshield
– Inconsistent performance from the adaptive cruise control

While not widespread, these issues highlight the importance of thorough inspection and maintenance.

Buying Advice

When shopping for a 2020 Forester, ask about the battery’s age and condition. Check for any aftermarket electronics that could contribute to parasitic draw. Test all electrical features, including lights, wipers, and infotainment.

Also, verify that all available software updates have been installed. A well-maintained 2020 Forester can be a solid choice, but it’s wise to be cautious.
