The 2019 Subaru Outback has accumulated over 1,000 NHTSA complaints. The 2017 has 913. Both years had two to four factory recalls. That gap between recall count and complaint volume tells the story of the 5th gen Outback: issues that Subaru addressed slowly, incompletely, or only after litigation.
Three separate class-action lawsuits touched this generation. One for windshield defects. One for the StarLink infotainment system. One for the EyeSight false-braking system. Subaru settled all three. The CVT was extended to 10 years or 100,000 miles under a separate technical service bulletin. If those facts make you want to skip it entirely, fair enough. But the 5th gen Outback is also a deeply practical all-wheel-drive wagon that routinely crosses 200,000 miles with proper maintenance. The issues are real and documented. So is the path through them: buy the right powertrain, target the right model year, and know exactly what to inspect.
This Generation at a Glance
The 5th gen Outback (BS platform) ran from 2015 through 2019. Production splits cleanly into two periods. The pre-facelift years (2015-2017) used Fujitsu Ten head units and a 6.2" or 7" StarLink touchscreen depending on trim. The 2018 refresh brought a restyled front end, a new Harman-built head unit, and factory Apple CarPlay and Android Auto, the first on any Outback. The 2019 carried the refresh forward with minor updates.
Two engines ran the full generation without change:
| Powertrain | Years Available | HP / TQ | Transmission | MPG (Combined) |
|---|---|---|---|---|
| FB25 2.5L H4 | 2015-2019 | 175 hp / 174 lb-ft | Lineartronic CVT | 28 |
| EZ36D 3.6L H6 | 2015-2019 | 256 hp / 247 lb-ft | 6-speed automatic | 22 |
The engine choice maps directly to the transmission. Every 2.5i is a CVT. Every 3.6R is a conventional 6-speed automatic. That distinction is the most important variable in this generation.
Subaru's symmetrical all-wheel-drive system is standard across all trims. There is no FWD option in the 5th gen Outback.

FB25 2.5L Flat-Four (2.5i Trims)
The FB25 is in the overwhelming majority of 5th gen Outbacks on the used market. It's a capable engine with a well-documented set of failure modes. Know them before you look at a single car.
Oil Consumption. The FB25 burns oil in a meaningful percentage of examples. Not catastrophically in most cases, but consistently enough that Subaru addressed it in court. The threshold for piston ring replacement is roughly one quart consumed every 1,200 miles. At that rate, the short block needs work. Repair cost: $2,500 to $3,800. There is no way to know from the outside whether a given FB25 is a consumer or not. The only pre-purchase screen: service records showing oil levels checked between changes. If the oil is a quart low at 5,000 miles between services, you have your answer.
Owners on subaruoutback.org forum threads going back to 2016 repeatedly cite oil consumption as the issue that catches them off guard at 60,000 to 100,000 miles, particularly on 2015 and early 2016 production cars. Later examples appear improved, but the problem was never fully eliminated in the generation.
Cam Carrier Seal Leaks. The FB25 uses a cam carrier cover whose factory sealing was insufficient on early production examples. Oil seeps from the junction between the carrier and cylinder head, typically surfacing between 60,000 and 120,000 miles. The repair requires pulling the engine. Dealer quotes run $2,300 to $4,600. Subaru issued multiple TSBs including 02-170-17R and later revised the factory sealing method, with 2017 and later examples being less affected. On any 2015 or 2016 with over 70,000 miles, this is not a hypothetical: get the underside of the engine inspected on a lift before committing. Look for oil film or residue along the perimeter of the rear cylinder head.
CVT Shudder and Stall. The Lineartronic CVT in the 2.5i Outback has a documented internal failure mode tied to the torque converter thrust washer. The original washer uses a solid bushing design that wears, generating metal debris. That debris eventually restricts the lockup clutch release ports, causing the converter to stay engaged at idle and the transmission to stall under load. Before full failure, drivers feel a shudder or vibration at 20 to 40 mph during gentle acceleration.
Subaru addressed the design in TSB 16-90-13R, which introduced a needle bearing design replacing the bushing washer. Production change point was around transmission serial number 633208. CVT replacement runs $4,800 rebuilt or up to $8,500 new. Subaru extended the CVT warranty to 10 years or 100,000 miles under TSB 16-107-17, covering 2010 through 2018 model years. If a car you're considering still falls within that window and shows shudder symptoms, it may qualify for covered repair. Confirm with a Subaru dealer before purchase.
Owner reports on subaruoutback.org consistently mention the shudder emerging between 60,000 and 100,000 miles on examples where CVT fluid was changed infrequently or never. The fix: verify the CVT fluid has been changed and change it again immediately upon purchase regardless. Dealer CVT fluid service runs $150 to $300. Independent shops that stock Subaru-spec fluid (Idemitsu) typically run $100 to $200.
StarLink Infotainment (2015-2017 Fujitsu Ten Units). The pre-2018 Outback used a Fujitsu Ten-built head unit running Subaru's StarLink software. Screen blackouts, random reboots, and frozen displays are documented across all 2015-2017 Outbacks. Roughly half of owners in a Torque News owner survey reported some form of StarLink issue. The 2016 Outback generated 251 electrical system NHTSA complaints, the highest raw electrical complaint count in the generation and many traced to infotainment failures. Software updates help temporarily. Hardware replacement is the only durable fix.
EZ36D 3.6L Flat-Six (3.6R Trims)
The 3.6R makes 256 hp and 247 lb-ft and pairs with a conventional 6-speed automatic. No CVT. No thrust washer. No cam carrier class action history. That's the core of the case for paying more for a 3.6R.
The EZ36D's known issues are mechanical wear items, not structural failures. The serpentine belt tensioner can seize at high mileage. Oil gaskets and seals weep past 100,000 miles. Timing chain tensioner inspection is sensible past 120,000 miles. None of these produce a surprise $4,000 repair bill. The 6-speed automatic's reliability record is excellent.
The EZ36D 3.6R takes 7 quarts of oil versus 5.1 for the FB25. Six spark plugs instead of four. Combined fuel economy drops to 22 mpg versus 28 for the CVT. The annual fuel cost difference is approximately $450 at current national average gas prices, per EPA data. Maintenance costs run modestly higher. The absence of CVT-related risk more than compensates.
Forum consensus on subaruoutback.org and NASIOC is consistent: given two otherwise comparable 5th gen Outbacks at similar prices, take the 3.6R. The caveat is that 3.6R examples always came in Limited or Touring trim, so they start higher in the used market.
Comparing equivalent mileage. A 2017 3.6R Limited at 90,000 miles typically represents a lower repair risk than a 2017 2.5i Limited at 70,000 miles, assuming reasonable fluid history. The 3.6R simply doesn't have the 2.5i's two most expensive failure modes.
2018-2019 StarLink (Harman Gen 3.0 Units). The 2018 refresh replaced the Fujitsu Ten unit with a Harman-built head unit that added CarPlay and Android Auto. The Harman unit is subject to a separate $6.25 million class action settlement (final approval June 2020) covering 2018 Outback, Legacy, Forester, Crosstrek, Impreza, and BRZ models. Plaintiffs alleged the touchscreen delaminates, causing physical buttons to stick and register false inputs, producing uncontrolled reboot loops and overnight battery drain.
This affects both 2.5i and 3.6R buyers of 2018 models. Before buying any 2018 Outback, check whether the head unit was replaced under the settlement. A replaced unit will show a newer manufacturing date in the service records. If the original unit is still in the car, inspect it carefully.
Trim-Specific Notes
2.5i base: The one trim where EyeSight was commonly skipped as an option. Non-EyeSight cars have cheaper windshields to replace: $300 to $500 versus $700 to $1,200 with camera recalibration for EyeSight-equipped cars. The 5th gen's windshield cracking problem (class action settled, warranty extended to 8 years / unlimited miles for 2015-2016) makes windshield replacement cost a real ownership factor. If you don't need the safety tech and want to keep replacement costs down, a base 2.5i without EyeSight achieves that.
2.5i Limited: The most common used Outback you'll encounter. Features standard EyeSight in most examples, leather, heated seats, and navigation. The sweet spot for features-to-price in the 2.5i stack. The Harman Kardon audio upgrade appeared in this trim for 2017 and later production before being supplanted by the Harman head unit in 2018.
2.5i Touring: Top 4-cylinder trim. The price premium over Limited rarely makes sense in the used market unless condition is substantially better.
3.6R Limited: Entry into the six-cylinder stack. Standard EyeSight, leather, navigation. If budget allows, this is the guide's recommended target: specifically a 2016 or 2017 example.
3.6R Touring: Adds premium audio and a few convenience features. Marginal over Limited for used market purposes.
Which Model Years to Target
| Year | Recalls | Complaints | Key Facts | Verdict |
|---|---|---|---|---|
| 2015 | 5 | 499 | Most recalls in gen. EyeSight recall (15V366000). Early FB25 production. | Caution (2.5i) / OK (3.6R) |
| 2016 | 4 | 633 | 251 electrical complaints. Windshield class action covers this year. | Caution |
| 2017 | 4 | 913 | Highest complaint volume pre-refresh. | Caution (2.5i) / Good (3.6R) |
| 2018 | 2 | 792 | Refresh year. CarPlay added. Harman head unit (check for swap). | Good (3.6R) / Verify HU (2.5i) |
| 2019 | 2 | 1,024 | Fuel pump recall (20V218000). Most available listings. Best 2.5i features. | Best 2.5i buy / Good 3.6R |
2015: Five recalls, more than any other 5th gen year. The most significant is campaign 15V366000 covering EyeSight crash imminent braking behavior. Early FB25 production carried the highest cam carrier seal failure risk. For a 2.5i, this is the hardest year to buy with confidence. For a 3.6R, the engine risk profile is much more forgiving.
2016: The electrical complaint spike (251 in the NHTSA data) correlates with StarLink infotainment failures that were widespread but not recalled. Windshield class action coverage (8 years / unlimited miles) applies here, meaning a 2016 with an original windshield that cracks may still qualify for reimbursement. That coverage is a potential buyer benefit, not a reason to seek out a car with an existing crack.
2017: The highest complaint count of the pre-refresh years. Not because 2017 was uniquely worse mechanically, but because 2015-2016 complaints keep accumulating. Forum threads from subaruoutback.org dating to 2019 and 2020 consistently mention 2017 as the generation year with the most unresolved owner frustration. For a 3.6R, 2017 is one of the better buys: pre-Harman head unit, no fuel pump concern, maximum availability.
2018: Two recalls versus five for 2015. The infotainment concern flips: the Fujitsu Ten problems go away and the Harman delamination issue arrives. The $6.25 million class action settlement covering 2018 Outbacks makes this the year where head unit history matters most. A 2018 with a replaced Harman unit is a clean buy. One with an original delaminating unit is an immediate repair.
2019: Most listings available today (690 per CarScout market data). Fuel pump recall 20V218000 covers 2019 Outbacks: the impeller can deform and cause a no-start or stall. Verify it's been completed via VIN check. Cam carrier sealing improved in later production. If you're buying a 2.5i, 2019 is the year with the best feature set and the fewest structural concerns. Verify the fuel pump recall is done before taking delivery.
Sweet spot for 3.6R buyers: 2017 3.6R Limited. Six-cylinder, conventional automatic, pre-Harman head unit, post-worst-recall-period. 594 total 2017 Outback listings are currently available, with enough volume to find a clean example.
Sweet spot for 2.5i buyers: 2019 2.5i Limited or Touring. CarPlay standard, cam carrier sealing improved, fewest recalls, and the fuel pump recall is routine to verify and confirm.
Pre-Purchase Inspection Checklist
All 5th Gen Outbacks
- Run the VIN through a recall check at /tools/recall-lookup before the test drive. Confirm the fuel pump recall (20V218000) is completed on 2019 models. Confirm the EyeSight recall (15V366000) on 2015 models.
- Pull the oil dipstick. If the car is between service intervals and already a quart low, that's oil consumption in progress. Walk unless the seller has an explanation and records.
- Ask for documented service history. If no records exist for an Outback with over 70,000 miles, price accordingly and inspect conservatively.
- Check the windshield from multiple angles in direct sunlight. Stress cracks radiating from the defroster element area or along the lower border are the defect pattern. Get a quote before finalizing any deal.
FB25 2.5i Models
- At highway speed, lift off the throttle and re-apply gently in the 20 to 40 mph range. A shudder, vibration, or hesitation during this exact maneuver is CVT thrust washer wear. Budget $4,800 to $8,500 if you hear it, or walk.
- Listen to the cold start. A tick that is present at startup and fades completely at operating temperature is acceptable. A tick that persists at operating temperature and follows RPM changes warrants more scrutiny.
- Ask when the CVT fluid was last changed. No record means change it immediately: budget $150 to $300.
- On any 2015 or 2016 with over 70,000 miles: have an independent Subaru specialist inspect the underside with the car on a lift. Look specifically for oil film or dark residue along the rear cylinder head perimeter where the cam carrier seats.
EyeSight-Equipped Models
- On the test drive, verify the EyeSight system shows no warning lights and the cameras (visible behind the rearview mirror base) are clear and unobstructed.
- Ask whether the windshield has ever been replaced. A replaced windshield without EyeSight recalibration produces false braking. If replaced, ask for the recalibration service record.
- Test adaptive cruise control on the highway. A system that brakes unexpectedly when no obstacle is present is a camera alignment or calibration issue.
2018-2019 Harman Head Unit
- Power on the infotainment system and press each physical button around the volume and tuning controls. Any button that feels sticky, rattles, or causes the screen to flicker or cycle is delamination. That's a repair, not a quirk.
- Check service records for head unit replacement under the StarLink settlement. A replaced unit resolves the issue. An original delaminating unit needs replacement.
- Start the car, leave the infotainment on, and let it sit for five minutes. A unit that spontaneously reboots during that window is in active failure.
Running Costs
| Powertrain | Combined MPG | Est. Annual Fuel | Key Service Items | Est. Annual Repair |
|---|---|---|---|---|
| FB25 2.5i CVT | 28 | ~$1,550 | CVT fluid every 30k ($150-$300), oil 5.1 qt, EyeSight windshield $700-$1,200 | ~$600 avg. |
| EZ36D 3.6R 6AT | 22 | ~$2,000 | Serpentine tensioner at 100k+, oil 7 qt, plugs (6) | ~$500 avg. |
Annual fuel cost from EPA data. Annual repair estimate from RepairPal Subaru Outback data.
CVT fluid on the 2.5i. The owner manual specifies longer intervals. Ignore them. Forum owner experience and Subaru's own warranty extension (triggered by widespread failures) both point to the same conclusion: change the CVT fluid every 30,000 miles. Use Subaru-spec fluid (Idemitsu NS-2 or Subaru-branded equivalent). Wrong fluid accelerates wear. Cost per service: $150 to $300.
EyeSight windshield. The 5th gen Outback has a documented windshield cracking problem. The EyeSight cameras live inside the windshield header. Every replacement requires camera recalibration: add $200 to $400 on top of the glass itself. A non-EyeSight car avoids this cost. A 2.5i base without EyeSight pays $300 to $500 per windshield. A Limited or 3.6R with EyeSight pays $700 to $1,200. On a car known for windshield cracking, this matters.
Cam carrier reseal. Not a maintenance item, but budget for it on 2015-2016 examples. It is not a question of if but when on early production FB25 engines. $2,300 to $4,600 when it comes up.
FAQ Block
Is the 5th gen Subaru Outback FB25 2.5i reliable? It's reliable with diligent maintenance but carries three documented failure modes: oil consumption, cam carrier seal leaks at 60k-120k miles, and CVT thrust washer failure. The CVT is extended to 10 years / 100k miles on applicable cars. Budget $150-$300 for immediate CVT fluid change and inspect for cam carrier seepage on any example over 70,000 miles.
What year 5th gen Subaru Outback should I avoid? The 2015 2.5i has the highest early production cam carrier and oil consumption risk. The 2016 and 2017 had the most electrical system complaints in the generation. For a 2.5i, 2019 is the cleanest choice. For a 3.6R, 2017 is the value sweet spot. Avoid any year where CVT fluid history is unknown or where the Harman head unit (2018) shows physical delamination.
Is the Subaru Outback 3.6R more reliable than the 2.5i? In practice, yes. The EZ36D pairs with a conventional 6-speed automatic instead of the CVT, which removes the 2.5i's two most expensive failure modes. It costs more to buy, costs more to fuel by roughly $450 per year, and has higher per-service oil costs. For buyers planning to keep the car past 120,000 miles, the 3.6R is the lower-risk choice.
Does the 5th gen Outback CVT have an extended warranty? Subaru extended the CVT warranty to 10 years or 100,000 miles under TSB 16-107-17, covering 2010 through 2018 model year Outbacks with the Lineartronic CVT. If the vehicle you're considering is within that coverage window and shows shudder symptoms, verify with a Subaru dealer before purchase. The repair cost without warranty is $4,800 to $8,500.
How many miles can a 5th gen Subaru Outback reach? Well-maintained examples with the 3.6R regularly reach 200,000 to 250,000 miles. The 2.5i can too, but longevity is tightly linked to CVT fluid service history. Subaru models that followed oil change intervals and CVT fluid schedules routinely cross 200,000 miles. The ones that didn't often show transmission and engine wear in the 80,000 to 130,000 mile window.
Bottom Line
Buy the 3.6R if your budget allows. The conventional 6-speed automatic eliminates the CVT and cam carrier risk that define the 2.5i ownership experience. A 2017 3.6R Limited in solid condition with verifiable fluid history is the target. If the 2.5i is the buy, go 2019, confirm the fuel pump recall (20V218000) is completed, change the CVT fluid on delivery, and have a Subaru specialist check the cam carrier area before you commit.
