Why Do Some Subaru Forester Years Have More Problems?
Car models change from year to year. Sometimes manufacturers introduce new engines, transmissions, or features. These updates can improve a car, but they can also bring unexpected problems if not tested well. For the Forester, several years had major changes that led to common issues. Other years, cost-cutting or supplier changes affected parts quality.
The most reported Subaru Forester problems include:
- Engine failures (especially head gasket leaks)
- Excessive oil consumption
- Transmission problems
- Electrical issues
- Air conditioner failures
- Suspension and steering troubles
Many of these issues are expensive to fix. Some can even make the car unsafe or unreliable. Understanding which years are most risky helps you avoid these headaches.
Subaru Forester Years To Avoid: The Main Offenders
Car complaints data, owner forums, and expert mechanic reports all point to certain Forester years with more problems than average. Here are the most problematic Subaru Forester model years:
1. 2014 Subaru Forester
The 2014 model marked the start of the Forester’s fourth generation. While it brought a new look and improved features, it also came with many issues. The 2014 Forester is often named the worst year by owners and experts.
Main issues:
- Excessive oil consumption: Many owners reported that the engine burns oil much faster than expected. Some had to add a quart every 1,000 miles. Subaru even faced a class-action lawsuit over this.
- Transmission problems: The new CVT (continuously variable transmission) often failed early, leading to expensive repairs or replacements.
- Electrical glitches: Problems with backup cameras, infotainment systems, and sensors were common.
- Suspension noise: Clunks and rattles from the front suspension frustrated many drivers.
One reason for these problems is that 2014 was a major redesign year. It’s common for first-model years of a new generation to have more “teething” issues.
2. 2015 Subaru Forester
While a little better than 2014, the 2015 Forester still had many of the same problems. Oil consumption was still high, and transmission complaints continued.
Main issues:
- Oil burning: Subaru offered short-term fixes, but many cars needed full engine rebuilds.
- Windshield problems: Owners reported spontaneous cracks and weak glass.
- Air conditioning failures: Repairs were costly and sometimes recurring.
3. 2011 Subaru Forester
The 2011 Forester was hit hard by the notorious Subaru head gasket problem. While previous years also had issues, complaints peaked around 2011.
Main issues:
- Head gasket leaks: This expensive engine repair often appeared before 100,000 miles.
- Suspension wear: Struts and bushings failed early, leading to rough rides and uneven tire wear.
- Wheel bearing noise: Many needed replacements sooner than expected.
4. 2010 Subaru Forester
This year had many of the same problems as 2011, especially with the engine and suspension.
Main issues:
- Excessive oil consumption
- Early head gasket failure
- Premature clutch wear (manual transmission models)
- Electrical problems
5. 2017 Subaru Forester
While newer, the 2017 Forester faced complaints about the new EyeSight safety system. False alarms, braking problems, and sensor failures caused frustration.
Main issues:
- EyeSight system glitches: Sudden braking, error messages, and expensive sensor recalibrations.
- Transmission hesitation: Delayed acceleration and rough shifting, especially in cold weather.
- Windshield cracking: Reports continued from earlier years.
6. 2009 Subaru Forester
The 2009 model was the first year of the third-generation Forester. Like other first-year redesigns, it had more problems.
Main issues:
- Engine oil consumption
- Head gasket leaks
- Interior rattles
- Sunroof problems: Leaks and mechanical failures.
7. 2001–2003 Subaru Forester
Going back further, these years had some of the worst head gasket problems and rust issues.
Main issues:
- Blown head gaskets: Repairs often cost $1,500 or more.
- Rust: Especially in the wheel wells and underbody.
- Wheel bearing failures
- Air conditioning failures
Problem Frequency: Comparing Risky Forester Years
To better understand how these years compare, here’s a look at owner complaints for the most problematic Forester years. This data is based on reports to CarComplaints. com and the National Highway Traffic Safety Administration (NHTSA).
| Model Year | Top Complaints | Average Repair Cost | Common Mileage When Issues Appear |
|---|---|---|---|
| 2014 | Engine, Transmission, Electrical | $2,000+ | 40,000–80,000 miles |
| 2011 | Engine (head gasket), Suspension | $1,500–$2,200 | 75,000–110,000 miles |
| 2009 | Engine, Interior, Sunroof | $1,000–$2,500 | 60,000–100,000 miles |
| 2015 | Engine (oil consumption), Glass | $1,000–$1,800 | 30,000–70,000 miles |
| 2001–2003 | Engine (head gasket), Rust | $1,200–$1,600 | 80,000–120,000 miles |
Why Are Head Gasket Problems So Common?
If you’ve researched older Subarus, you’ve probably seen the words head gasket many times. The head gasket sits between the engine block and the cylinder head, sealing coolant and oil passages. When it leaks, you can get:
- Coolant in the oil (white, milky oil)
- Overheating
- Loss of engine power
- White smoke from the exhaust
Subaru’s “boxer” engine design (horizontally opposed cylinders) is part of the reason. Oil and coolant sit in ways that can stress the gasket, especially as the engine ages. In the late 1990s to early 2010s, Subaru used a gasket material that often failed early.
Repair costs: Head gasket jobs usually cost $1,200–$2,000 at a shop. Many owners replaced the gasket, only to have another leak a few years later if the shop used similar parts or skipped related repairs.
Non-obvious insight: If you find a used Forester from these years, ask for proof of head gasket replacement. A car with a new, high-quality gasket (like an MLS type) can be reliable. Without this, walk away.
Oil Consumption Issues: What’s The Risk?
Many modern Subarus, especially from 2010–2015, burn oil faster than expected. Some use a quart every 1,000–2,000 miles. This isn’t just annoying—it can destroy an engine if the oil runs low.
Why does it happen?
- Piston ring design: Subaru made the rings thinner for better fuel economy, but this let oil slip past.
- Break-in procedures: Early miles are critical. If not broken in properly, oil use can get worse.
What to watch for:
- Check the oil level before every gas fill-up.
- Look for blue smoke from the exhaust.
- Ask the seller about oil top-offs and service records.
Non-obvious insight: Subaru offered an “oil consumption test” for some models. If the car failed, they sometimes replaced the short block under warranty. If you’re buying a used Forester, ask if this test was done.
Transmission Problems: Cvt Troubles
Subaru switched to a CVT (continuously variable transmission) in the fourth-generation Forester (2014+). CVTs can feel smoother and improve fuel economy, but they have unique problems.
Common symptoms:
- Hesitation when accelerating
- Shuddering or jerking
- Warning lights
- Delayed engagement when shifting from park to drive
Repair costs: A failed CVT often means replacement, not repair. This can cost $4,000 or more—often more than the car’s value.
Should you avoid all CVT Foresters? Not necessarily. Later years (2018+) had fewer issues. But always test drive and check for smooth operation.
Other Common Forester Problems
Besides the big three (engine, oil, transmission), some Forester years had other issues:
- Windshield cracking: 2015–2018 models are known for easy-to-crack glass. Replacements can cost $500 or more, and insurance may not cover it.
- Electrical system glitches: Backup cameras, infotainment, and warning lights often fail in newer models.
- Suspension noise: Early strut and bushing wear leads to clunks and poor handling.
- Rust: Older Foresters (especially 2001–2008) rust quickly in cold climates.
Subaru Forester Years Known For Reliability
Not all Foresters have problems. Some years stand out for their durability and owner satisfaction. If you’re looking for a used model, these years are generally safe bets:
- 2004–2008: These years had fewer head gasket problems (especially after 2006) and are simple to repair.
- 2016: Fewer engine and transmission complaints, improved safety features.
- 2018–2020: More reliable CVT, better build quality, and improved EyeSight system.
- 2021–2023: The newest models have the latest safety technology and the fewest complaints so far.

What To Check When Buying A Used Subaru Forester
If you’re set on a Forester, a careful inspection is essential, especially for years with known problems. Here’s what to do:
- Ask about the head gasket: Get proof of replacement, especially for 1999–2011 models.
- Check for oil burning: Look for blue exhaust smoke and check the oil level after a test drive.
- Listen for suspension noise: Drive on bumpy roads and listen for clunks.
- Test all electronics: Try the air conditioning, backup camera, and infotainment.
- Look for windshield cracks: Even small chips can grow quickly.
- Inspect for rust: Check under the car, around the wheel wells, and on the rear hatch.
- Scan for warning lights: A “check engine” or ABS light can signal expensive repairs.
- Drive the car cold: Transmission and engine issues often show up when the car is first started.
Tip: If you’re not confident inspecting a car, pay for a trusted mechanic’s pre-purchase inspection. This can save you thousands of dollars and help you avoid a problem car.
How Subaru Responded To Forester Problems
Subaru didn’t ignore these issues. Over the years, they made several changes:
- Improved gasket materials: After 2012, Subaru switched to better head gaskets.
- Engine updates: Later models have improved piston rings, reducing oil burning.
- CVT upgrades: Software and hardware updates have made CVTs more reliable in 2018+ models.
- Extended warranties: In some cases, Subaru offered longer warranties for engines or transmissions.
But these fixes don’t always help used car buyers. Unless the repair was done on your potential Forester, the risk remains.
Should You Avoid Older Subaru Foresters Completely?
Older Subarus (especially 1999–2011) have a reputation for engine issues. But they also have fans who swear by their durability if maintained well. Here’s what to consider:
- Parts are cheap and easy to find.
- Many mechanics know how to fix them.
- If problems are repaired with quality parts, they can last past 200,000 miles.
However, if you want a “buy and drive” experience with little hassle, it’s safer to choose a newer, more reliable year.
