Why Model Year Matters When Buying a Used Subaru Forester

When shopping for a used car, the model year is one of the most critical 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, electronics, and suspension setups. While innovation is great, it sometimes comes with growing pains.

For example, the transition from the third-generation (2008–2012) to the fourth-generation (2013–2018) Forester brought a new 2.5L FB-series engine and a revised chassis. While these updates improved fuel efficiency and ride comfort, they also introduced new issues like oil consumption and CVT transmission quirks. Similarly, the fifth-generation Forester (2019–present) brought a more modern infotainment system and improved safety features—but not without some early electrical gremlins.

Understanding these generational shifts helps explain why some years are more problematic than others. It’s not just about age; it’s about what was happening under the hood and behind the dashboard during that specific production run. By identifying the years with the highest failure rates and most frequent complaints, you can focus your search on the most reliable options and avoid the ones that are more likely to give you trouble down the road.

Top Subaru Forester Years to Avoid (And Why)

While the Subaru Forester has earned a solid reputation overall, a few model years stand out as particularly problematic. These are the ones you should approach with caution—or avoid altogether unless you’re prepared for potential repairs and close monitoring.

2014–2015: The Oil Consumption Nightmare

The 2014 and 2015 Subaru Forester models are perhaps the most notorious in the lineup due to a widespread issue with excessive oil consumption. Owners reported burning through a quart of oil every 1,000 to 1,500 miles—far beyond the acceptable range. This wasn’t just a minor annoyance; it could lead to low oil levels, engine knocking, and eventually, catastrophic engine failure if left unchecked.

The root cause was traced to faulty piston rings and a defective positive crankcase ventilation (PCV) system. The piston rings didn’t seal properly, allowing oil to seep into the combustion chamber and burn off. Subaru eventually issued a technical service bulletin (TSB) and extended the warranty for affected vehicles, but many owners still faced costly repairs out of pocket.

If you’re considering a 2014 or 2015 Forester, you must check the oil level frequently—ideally every time you fill up the gas tank. Look for signs of oil burning, such as blue smoke from the exhaust or a strong oil smell. Also, verify whether the vehicle has had the piston ring replacement or PCV system repair performed under warranty. Even then, some owners report that the fix didn’t fully resolve the issue.

2016–2017: CVT Transmission Troubles

The 2016 and 2017 Subaru Forester models introduced a newer version of the continuously variable transmission (CVT), which was supposed to offer smoother shifting and better fuel economy. Unfortunately, many owners found the opposite. Common complaints included jerky acceleration, hesitation when merging or climbing hills, and a “rubber band” feeling during throttle input.

In more severe cases, the CVT would fail prematurely, requiring a full replacement that could cost $4,000 or more. Subaru acknowledged the issue and issued software updates to improve shift logic, but some drivers still reported persistent problems. Additionally, the CVT’s reliance on a torque converter and belt system makes it more complex—and potentially less durable—than a traditional automatic transmission.

If you’re looking at a 2016 or 2017 Forester, pay close attention to how the transmission behaves during a test drive. Does it hesitate when you press the gas? Does it make unusual noises or shudder under load? Ask for maintenance records to see if the transmission fluid has been changed regularly—CVTs are sensitive to fluid condition. And consider having a Subaru specialist inspect the vehicle before buying.

2019: Head Gasket Woes Return

The head gasket issue is a well-known Achilles’ heel for older Subarus, particularly those with the EJ-series engines. While Subaru made significant improvements with the newer FB-series engines, some 2019 Forester owners still reported head gasket leaks. These leaks can lead to coolant loss, overheating, and engine damage if not addressed quickly.

The problem seems to be more prevalent in vehicles that were driven in hot climates or subjected to frequent towing. Symptoms include white smoke from the exhaust, a sweet smell from the engine bay, and low coolant levels with no visible leaks. In some cases, the leak occurs between the engine block and cylinder head, requiring a costly repair that involves removing the engine.

Subaru has not issued a formal recall for 2019 head gasket issues, but there are numerous reports on owner forums and repair databases. If you’re considering a 2019 Forester, inspect the engine bay for signs of coolant residue or oil mixing. Check the coolant reservoir and radiator for contamination. And again, a pre-purchase inspection is essential.

2020: Early Electrical and Infotainment Glitches

The 2020 Subaru Forester marked the second year of the fifth generation, bringing a refreshed interior, updated Starlink infotainment system, and advanced driver-assistance features like EyeSight. While these upgrades were welcome, early 2020 models suffered from a range of electrical issues.

Common problems included the infotainment screen freezing or rebooting randomly, the backup camera failing to display, and the vehicle’s battery draining overnight. Some owners also reported issues with the keyless entry system and automatic headlights not functioning properly. These glitches were often traced to software bugs or faulty control modules.

Subaru released several over-the-air updates and dealership software patches to address these issues, but not all vehicles received them. If you’re looking at a 2020 Forester, make sure the infotainment system is running the latest software version. Test all electronic features during your test drive, including the camera, Bluetooth, and climate controls. Also, check the battery health—parasitic drain can be a sign of deeper electrical problems.

2013: Timing Chain Tensioner Failures

While not as widely discussed as oil consumption or CVT issues, the 2013 Subaru Forester had its own share of problems—specifically with the timing chain tensioner. The tensioner is a critical component that keeps the timing chain tight and properly aligned. If it fails, the chain can slip, causing the engine’s valves to collide with the pistons—a catastrophic event known as “valve-to-piston interference.”

Symptoms of a failing tensioner include a rattling noise from the engine at startup, especially when cold. If you hear this sound, it’s a red flag. Subaru issued a TSB for this issue and extended the warranty on the timing chain components, but many owners were unaware of the problem until it was too late.

If you’re considering a 2013 Forester, listen carefully during startup. Ask the seller if the timing chain and tensioner have been inspected or replaced. And again, a professional inspection can help detect early signs of wear.

Reliable Subaru Forester Years to Consider Instead

Now that we’ve covered the years to avoid, let’s talk about the Forester models that have proven to be more reliable and trouble-free. These are the years where Subaru got it right—offering solid performance, good fuel economy, and fewer major issues.

2018: The Sweet Spot for Fourth-Gen Foresters

The 2018 Subaru Forester is widely regarded as one of the most reliable models in the fourth generation. By this year, Subaru had addressed many of the oil consumption and CVT issues that plagued earlier models. The 2.5L FB25 engine was refined, and the CVT received software updates that improved responsiveness and durability.

Owners report excellent fuel economy (around 26–28 mpg combined), smooth handling, and strong reliability. The 2018 model also comes with standard EyeSight safety features, including adaptive cruise control and lane departure warning. It’s a great choice for buyers who want a well-equipped, dependable SUV without breaking the bank.

2021–2023: Fifth-Gen Refinements

The 2021, 2022, and 2023 Subaru Forester models benefit from years of refinement in the fifth generation. Subaru has resolved most of the early electrical issues, and the infotainment system is now more stable and user-friendly. The 2.5L engine remains reliable, and the CVT continues to improve with each model year.

These newer Foresters also come with enhanced safety features, including automatic emergency braking, blind-spot monitoring, and rear cross-traffic alert. They’re ideal for buyers who want the latest technology and peace of mind. Just be sure to check for any open recalls and verify that all software updates have been applied.

2009–2012: Proven Durability (With Caveats)

If you’re open to older models, the 2009–2012 Subaru Forester (third generation) can be a solid choice—especially if you find one with a manual transmission. These models use the older EJ25 engine, which is known for its durability when properly maintained. However, they are more prone to head gasket failures, so regular coolant checks are a must.

Look for a well-maintained example with service records, and avoid high-mileage vehicles unless they’ve had the head gasket replaced. The manual transmission models are generally more reliable than the automatic ones, and they offer a more engaging driving experience.

How to Avoid Buying a Problematic Subaru Forester

Even if you steer clear of the worst model years, there’s still a chance you could end up with a lemon. Here are some practical tips to help you make a smart purchase:

Get a Pre-Purchase Inspection (PPI)

This is non-negotiable. A PPI by a trusted mechanic—preferably one familiar with Subarus—can uncover hidden issues that aren’t obvious during a test drive. The inspector will check the engine, transmission, suspension, brakes, and electrical systems. They’ll also look for signs of previous repairs, accident damage, or deferred maintenance.

Check the Vehicle History Report

Use services like Carfax or AutoCheck to get a detailed history of the vehicle. Look for accidents, flood damage, title issues, and odometer discrepancies. A clean report doesn’t guarantee a problem-free car, but it’s a good starting point.

Review Maintenance Records

A well-documented service history is a strong indicator of a well-cared-for vehicle. Look for regular oil changes, transmission fluid replacements, and brake inspections. If the seller can’t provide records, that’s a red flag.

Test Drive in Real-World Conditions

Don’t just drive around the block. Take the Forester on highways, hills, and stop-and-go traffic. Pay attention to how the engine responds, how the transmission shifts, and whether any warning lights come on. Listen for unusual noises and feel for vibrations or pulling.

Use Subaru’s VIN Lookup Tool

Subaru offers a free VIN lookup tool on its website that shows any open recalls, warranty claims, and service bulletins for the vehicle. Make sure all recalls have been addressed before you buy.
