The picture

Is the Subaru Outback or Subaru Legacy more reliable?

A plain-English read on what the NHTSA record says about living with each vehicle.

Subaru Outback

The Subaru Outback, a popular wagon/SUV, has a high complaint rate of about 453 per year over the last decade, with visibility/wiper and electrical issues dominating. Owners report shattered moon roofs and easily cracked windshields, as well as battery failures that strand drivers. The sheer volume suggests these are common frustrations for owners.

Subaru Legacy

The Subaru Legacy sedan has far fewer complaints, averaging about 57 per year. Its top issues are also visibility/wiper and electrical, but with less intensity. Owners describe windows rolling down on their own and battery deaths, but the overall pattern is less severe than the Outback.

What actually goes wrong

The problems owners report

The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

What these mean
VISIBILITY/WIPER

Owners report moon roofs shattering spontaneously within days of ownership and windshields cracking from small pebbles, with replacement delays of months. This suggests fragile glass that can fail without impact.

ELECTRICAL SYSTEM

Battery systems fail to hold charge, causing complete no-starts and stranding, even on low-mileage vehicles. The Eyesight system also becomes inoperable, disabling driver assists.

UNKNOWN OR OTHER

Some owners report HVAC systems heating to dangerous levels (over 100°F) even when turned off, and fixed-height passenger seats positioned too high, creating crash-compatibility concerns.

What these mean
VISIBILITY/WIPER

Windows roll down on their own when the vehicle is off, a recurring issue that dealers sometimes fail to fix. Windshields also develop stress cracks without impact, interfering with Eyesight.

ELECTRICAL SYSTEM

Batteries die prematurely, leaving owners stranded, even on nearly new cars with low miles. The heater and Eyesight system may fail simultaneously in cold weather.

ENGINE

Engines can develop loud knocking/tapping noises without warning, making the vehicle unsafe to drive. The thermo control valve may fail, requiring costly repairs (over $2,000) not covered for rebuilt-title cars.

In owners' words — VISIBILITY/WIPER

When the vehicle is off the windows will come down on their own! This has occurred on 4 difference instances. One dealership indicated the "fix" the situation; however, they never replaced the parts which were required for the fix. A second dealership would n…

Buyer analysis

Subaru Outback or Subaru Legacy: which should you buy?

The Subaru Legacy has far fewer complaints per year (57 vs 453), indicating a lower likelihood of encountering problems. In practice, Legacy owners face less frequent glass and electrical failures, making it a more predictable choice for reliability.

Recommendation. If you prioritize lower complaint rates and fewer electrical/glass issues, choose the Legacy. If you need the Outback's cargo space and higher ground clearance, be prepared for more frequent visits to the dealer for moon roof, windshield, and battery problems.

Key differences

  • Outback has 8x more complaints per year than Legacy, with glass failures (moon roof shattering, windshield cracking) being a standout issue.
  • Legacy owners report windows rolling down on their own, a unique quirk not seen in Outback complaints.
  • Outback electrical failures often involve the battery and Eyesight, while Legacy also has engine knocking and thermo control valve failures.
  • Both share similar recall subjects (driveshaft, transmission park interlock), but Outback has more recalls overall (26 vs 21).
Watch on Subaru Outback
  • Inspect the moon roof for cracks or signs of stress, and check the windshield for any chips or cracks, as these are common failure points.
  • Test the battery and starting system; ask if the battery has been replaced, as premature failure is a known issue.
Watch on Subaru Legacy
  • Check that all windows operate correctly and do not roll down when the car is off; ask about any previous window-related repairs.
  • Listen for engine knocking or tapping noises during a test drive, and verify the thermo control valve has been inspected or replaced if the car has over 60k miles.

Before you buy

  • Ask for service records showing any moon roof or windshield replacements on the Outback.
  • Test the Eyesight system on both vehicles to ensure it activates and stays on.
  • On the Legacy, operate each window switch and then lock the car to see if any window drops.
  • Check the battery age and condition; request a load test if possible.
  • Review the recall history for both vehicles and confirm any open recalls have been completed.
