🎯 The Verdict
📊 The Numbers by Model Year
Here is how each recent Forester generation stacks up on the metrics that actually predict ownership cost. Reliability scores blend Consumer Reports, RepairPal, and NHTSA complaint volume.
| Year | Engine / Trans | Reliability | Used Price | Verdict |
|---|---|---|---|---|
| 2018 | FB25 / CVT | 4.5 / 5 | $15k-$19k | Best overall |
| 2017 | FB25 / CVT | 4.5 / 5 | $13k-$17k | Best value |
| 2016 | FB25 / CVT | 4 / 5 | $11k-$15k | Strong buy |
| 2015 | FB25 / CVT | 4 / 5 | $10k-$13k | Solid budget pick |
| 2014 | FB25 / CVT | 3 / 5 | $8k-$11k | Higher CVT risk |
| 2011-2013 | FB25 / CVT | 2.5 / 5 | $6k-$9k | Oil burner risk |
| 2009-2010 | EJ25 / 4AT | 3.5 / 5 | $5k-$8k | Old but tough |
| 2003-2005 | EJ25 / 4AT | 2 / 5 | $3k-$6k | Head gasket bombs |
✅ Why 2015-2018 Is the Sweet Spot
Subaru quietly fixed a lot between the 2014 and 2015 model years. The headline change was updated piston rings on the FB25 engine, which dropped oil consumption complaints by roughly 70 percent according to NHTSA filings.
What got better
- Piston rings revised on the FB25 to fix the oil burning that triggered the 2011-2014 class action settlement.
- CVT software updates reduced shudder, hesitation, and the dreaded P0700 transmission code on early Lineartronic units. See our P0700 diagnostic guide for details.
- EyeSight driver assist became broadly available, adding adaptive cruise and pre-collision braking.
- Improved CVT fluid cooler on 2016+ models helps transmissions last past 200,000 miles when fluid is changed every 60,000.
- Stronger wheel bearings in the rear, which had been a chronic squeal-and-replace item on 2009-2013 cars.
If you want a Forester that just works, the 2017 Premium with EyeSight is the version most independent Subaru shops point owners toward. Expect 25 mpg combined and a maintenance budget around $400 per year if you stay on top of fluids.
⛔ The Years to Avoid (and Why)
2011-2014: The oil consumption era
The FB25 in these years can burn 1 quart of oil every 800 to 1,200 miles. Subaru's settlement covered short blocks under warranty, but most of those repairs are long expired. If you see one cheap, factor $3,500 to $5,500 for a short block rebuild into your offer. The check engine light P0420 code on these cars is often catalytic damage from oil in the exhaust, walk through our P0420 troubleshooting before you buy.
2014 specifically: CVT growing pains
The 2014 SJ generation launched the wider use of the TR580 CVT, and early production had software bugs that caused hesitation and occasional torque converter clutch failures. A 2014 with a documented CVT software flash and clean fluid is fine; one without records is a coin flip.
2003-2005: Head gasket roulette
The EJ25 SOHC head gasket is one of the most infamous failures in Subaru history. Most surviving examples have either had the gaskets replaced (good) or are about to need them (bad). Repair runs $1,800 to $2,600. If you see white smoke from the tailpipe or sweet smell from the exhaust, walk away. Our white smoke symptom guide covers what to look for on a test drive.
2019: First-year SK redesign
Not a disaster, but the 2019 had three recalls in the first year, including a CVT control module update. 2020 and later 5th-gen Foresters fixed most of the launch issues.
🔧 Common Mistakes When Buying a Used Forester
- Skipping the CVT fluid check. Subaru calls CVT fluid "lifetime" but every independent Subaru tech disagrees. A Forester past 80,000 miles with original fluid is a red flag, not a green one.
- Ignoring oil change records. On 2011-2014 cars, a thin paper trail almost guarantees oil consumption issues. Ask for receipts or walk.
- Trusting a clean Carfax alone. Carfax misses about 30 percent of accidents. Always get a pre-purchase inspection, especially on AWD systems where damaged differentials hide well.
- Overpaying for XT turbo models. The 2014-2018 Forester XT is fun but the turbo and direct injection add complexity. Carbon buildup at 80,000 miles is real.
- Assuming all-wheel drive equals invincible. Foresters need the same brake fluid, coolant, and timing service as any other car. See our how to check Subaru CVT fluid walkthrough before you hand over money.
🧭 Decision Framework: Which Year Fits You
If your budget is under $10,000
Look at a 2013 or 2014 base model with documented oil consumption testing and a CVT fluid service in the last 30,000 miles. Budget $1,500 in reserve for surprises.
If your budget is $10,000 to $15,000
This is 2015-2016 Premium territory. You get the fixed engine, decent CVT, and often EyeSight. Best dollar-per-reliability spot in the entire Forester lineup.
If your budget is $15,000 to $20,000
Go straight to a 2017 or 2018 Premium or Limited. Lower miles, full safety tech, and at least three to five more years of trouble-free driving if you maintain it.
If your budget is over $20,000
A 2020 or 2021 5th-gen Forester is the play. Skip 2019. The newer platform gets better crash scores and updated infotainment.
❓ Frequently Asked Questions
📝 Summary
If you want the shortest possible answer to which years of Subaru Forester are best: 2017 or 2018. They sit in the sweet spot of fixed engine, refined CVT, modern safety tech, and reasonable used pricing. Step down to a 2015 or 2016 if budget is tight. Walk past anything 2011-2014 unless the price reflects the engine risk, and treat 2003-2005 head gasket cars as project vehicles, not daily drivers.
Before you put down a deposit on any used Forester, pull the VIN and run a vehicle-specific reliability report. It is the cheapest insurance policy in car buying.
