2015 Subaru Outback: Performance and Safety Standards
The 2015 Subaru Outback doesn’t just meet the safety standards of its era—it set new ones, earning a Top Safety Pick+ and proving that a family wagon could also conquer a 400-foot snowy driveway like a mountain goat .
Here is the honest, unvarnished truth about the 2015 Outback. This generation was completely redesigned, and it nailed the big stuff: crash protection, all-weather capability, and long-term durability. But it also introduced some gremlins that you absolutely need to know about before you buy one.
TL;DR – The 2015 in One Paragraph
The 2015 Subaru Outback is a tale of two reputations. On one hand, it’s arguably the safest wagon Subaru had built to that point—IIHS Top Safety Pick+, five-star NHTSA rating, and EyeSight technology that stopped the car before impact in tests . On the other hand, it suffers from a notorious parasitic battery drain (thanks to a faulty telematics module) and some owners report premature wheel bearing failure . If you buy a 2015, verify the DCM recall was performed and listen for rear wheel bearing noise. Do that, and you’ve got a 200,000-mile sled that laughs at blizzards.
Key Takeaways – 2015 Outback, Nailed and Failed
- ✅ Safety is genuinely elite – IIHS “Good” in all crash categories; “Superior” front crash prevention rating with EyeSight .
- ✅ Two engines, two personalities – 2.5L makes 175 hp, returns 33 mpg highway. 3.6R makes 256 hp, guzzles fuel, pulls like a train .
- ✅ Ground clearance is 8.7 inches – That’s genuine off-road capability, same as many modern “soft-roaders” .
- ❌ DCM battery drain is real – Subaru acknowledged it, extended the warranty. If the previous owner never fixed it, the car will kill batteries .
- ❌ Rear wheel bearings fail early – Multiple reports of failure at 60k and again at 120k. Listen for a low howl that changes pitch when you sway the steering wheel .
- ❌ Power liftgate gremlins – Some owners had to disconnect the motor entirely because it refused to open .
The 2015 Redesign: Why This Generation Matters
The 2015 model wasn’t just a facelift. Subaru threw out the old chassis and built the Outback on a heavily revised platform with 80% new parts. They stiffened the structure, added more high-strength steel, and finally fixed the head gasket issues that plagued the older EJ engines .
**This is where *Subaru Global Platform* DNA started showing up**, even before the official name existed. You feel it in the steering. You feel it when you close the door—it sounds solid, not tinny.
The Boxer Engine Choice: Thrifty or Thirsty?
You have two options, and they drive like completely different vehicles.
The 2.5L Four-Cylinder
- 175 horsepower, 174 lb-ft torque
- 0-60 mph in about 9.3 seconds
- 25 city / 33 highway mpg
It’s adequate. Owners say it merges onto highways without drama and cruises quietly at 75 mph. One reviewer drove theirs to 220,000 miles through the Rocky Mountains and said power was “surprisingly adequate” even at altitude . The Boxer Engine layout keeps the weight low, so even the base engine feels planted.
The 3.6R Six-Cylinder
- 256 horsepower, 247 lb-ft torque
- 0-60 mph in 7.6 seconds
- 17 city / 25 highway mpg (if you’re lucky)
This is the enthusiast choice. Owners describe it as “a sleeper.” It doesn’t look fast, but it pulls hard from stoplights and tows 2,700 lbs with ease . The trade-off is brutal fuel economy. One owner admitted they get 21 mpg combined and called it “dismal” . You pay for the smoothness of that 6-cylinder Boxer at the pump.
“With the 6-cylinder mill, the gas mileage is dismal, but it climbs a 400-foot driveway in 10 inches of snow like a mountain goat.” — *Doghouse Riley, 2015 Outback 3.6R owner *
Timeline: How the 2015 Outback Safety Package Evolved
Pre-2015 Models
- Four-star NHTSA front crash rating
- Available backup camera (not standard)
- No EyeSight on most trims
2015 Model Year (Redesigned)
- Five-star NHTSA overall rating – Five stars in front crash test (beats Forester’s four stars)
- IIHS Top Safety Pick+ – “Good” in small overlap, moderate overlap, side, roof strength
- Superior front crash prevention – Avoided collision at 12 mph and 25 mph in testing
- Standard rearview camera
- Optional blind spot detection and rear cross-traffic alert
2016–2019 Updates
- Gradual refinement of EyeSight software
- 2017/2018 models introduced fragile windshield complaints (less common in 2015)
The 2015 model sits in a sweet spot. It has the modern safety structure without the later complaints about paper-thin glass and overly sensitive lane keep .
Real-World Safety: It Saved His Life
You can look at IIHS diagrams all day, but here is what matters. One owner bought a 2015 Premium with 214,000 miles on it. He drove it hard on aggressive off-road terrain in the Rockies—roads that would shake a Jeep to pieces.
Then he rolled it. At 60 mph.
He walked away without injuries.
His review is blunt: “Safety and reliability are top tier. Love the car, would buy it again if I had the chance” .
That is the reputation the 2015 earned. It’s not perfect. The battery thing is annoying. Wheel bearings fail. But when the moment comes, the structure holds.
Safety reminder: EyeSight helps prevent collisions, but it does not replace an attentive driver. Always keep your hands on the wheel and eyes on the road.

The Gremlins You Need to Know About
Let’s be honest about the 2015. It has known issues. If you’re shopping one, here is your checklist.
1. The Battery Killer (DCM Module)
This is the big one. The telematics module tries to call home on a 3G network that doesn’t really exist anymore. It keeps trying, failing, and draining your battery dead .
How to check: Ask if the DCM update was performed under the extended warranty. If the seller looks confused, assume it wasn’t done. This is a $0 fix at a dealership if the car is eligible. Do not skip this.
2. Rear Wheel Bearings
Multiple owners report failures at 60,000 miles. Some went through two sets by 120,000 .
How to check: Drive at 45–55 mph on a smooth road. Sway left and right gently. If you hear a low womp-womp-womp that changes with steering angle, the bearings are toast. Budget about $600–$800 per side.
3. Power Liftgate Meltdown
One owner described disconnecting the motor entirely because the hatch refused to open or close reliably . This isn’t universal, but it’s common enough to test.
Test it: Open and close the power hatch three times in a row. Does it hesitate? Does it beep and stop halfway? If yes, the struts or motor are failing.
4. Infotainment Glitches
Some owners report the center console screen freezing or the Bluetooth dropping calls. This is annoying but not expensive to live with.

FAQ – 2015 Subaru Outback Performance and Safety
Is the 2015 Subaru Outback reliable?
It depends which owner you ask. 93% of owners recommend it, but complaints about battery drain and wheel bearings are consistent . If the DCM recall is done and the bearings are quiet, it is very reliable.
How does the 2015 Outback perform in snow?
Exceptionally well. Owners report climbing steep, unplowed driveways with 10 inches of fresh snow using winter tires. Symmetrical AWD combined with 8.7 inches of ground clearance makes it one of the best winter vehicles of its era .
Is the 3.6R engine worth the extra fuel cost?
If you tow, drive mountain highways, or just enjoy acceleration, yes. The 256-hp 6-cylinder Boxer is smooth and the 7.6-second 0-60 time is genuinely quick for a wagon . If you mostly commute, stick with the 2.5L.
What is the real-world fuel economy of the 2.5L?
Owners report 24–26 city and 30–33 highway. The EPA ratings are accurate if you drive conservatively .
Did the 2015 Outback have any recalls?
Yes. The most significant is the DCM battery drain issue. Subaru issued an extended warranty for affected 2015–2020 models. Check with a dealership using the VIN .
Is the 2015 Outback safe by 2025 standards?
Structurally, yes. The IIHS small overlap and side impact tests from 2015 remain demanding even today . However, EyeSight version 1.0 lacks pedestrian detection and is less refined than modern systems.
What mileage is too high for a 2015 Outback?
One owner bought one with 214,000 miles and drove it hard with minimal repairs . High mileage is less important than maintenance history. Listen for wheel bearing noise and check if the CVT fluid was ever changed.
The Verdict: Should You Buy a 2015 Outback?
Here is the honest take.
If you find a 2015 Outback with the DCM recall completed, rear wheel bearings that are quiet, and a service history that includes CVT fluid changes—buy it. You will own one of the safest, most capable all-weather vehicles from the 2010s. It will haul your kids, your kayaks, and your dog for another 100,000 miles.
If you find a 2015 with a dead battery, a finicky hatch, and no records? Walk away. There are better examples out there.
The 2015 Outback is not perfect. But its imperfections are known, fixable, and forgivable—especially when you’re driving past spun-out trucks on a snowy pass and your wagon just keeps gripping.
