Kestrel Take

First year of the fifth-generation Legacy and the first year Subaru put its Lineartronic CVT in one, and the record is the CVT: powertrain and engine complaints together are 56% of 150, and most of them describe the same thing — a torque converter that stays locked as you slow down until the engine shudders and stalls at the stop sign, sometimes in traffic. Subaru extended the CVT warranty on these cars to ten years or 100,000 miles, and a 2010 is now past both. Behind that sit 18 recalls, ten of them Takata passenger airbag inflators. A 2010 Legacy with a torque converter already replaced on an invoice, the Takata work closed on the VIN, and a smooth roll to a stop is an honest, roomy all-wheel-drive sedan for very little money; one that shudders as it slows is a $2,000 bill waiting, and you should price it that way or walk. The 6-speed manual cars dodge the CVT entirely but carry two recalls of their own.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 150 owner complaints for the 2010 Subaru Legacy, and 18 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 33% of them are about one thing — the transmission and drivetrain. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

18 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2010 Subaru Legacy

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

CVT torque converter lockup makes the car shudder and stall coming to a stopHigh — wallet impact

The story of this car. Fifty powertrain and 35 engine complaints, three crashes among them, and the words that repeat are torque, converter, stop and stalls: the lockup clutch in the CVT's torque converter fails to release as the car slows, the engine gets dragged down, and it shudders and dies at the light — worst uphill or after a hard stop, and one owner was left dead in a busy intersection. Dealers quoted about $2,100 for the converter; Subaru later extended CVT coverage on 2010–2015 cars to ten years or 100,000 miles, which a 2010 has now aged out of. Also on this year, recall 10V196 covered a CVT cooler hose that can split and dump the fluid until the car stops. Ask for a converter or CVT invoice. On the test drive, make ten stops from 30 mph without touching neutral and feel for any shudder in the last five mph.

Repair cost (estimate): $1,200–$2,500 for a torque converter; $5,000–$8,000 for a replacement CVT — more than this car is typically worth

Takata passenger airbag inflator — ten recall campaigns — plus a failing passenger seat sensorHigh — wallet impact

Ten of this car's 18 recalls are the Takata passenger inflator, issued state by state and year by year from 16V358 through 20V003, because the inflator can rupture and throw metal into the cabin. Owners in this record were told parts were unavailable for months; by now they are not, and the NHTSA VIN lookup will show whether every campaign is closed. The rest of the 28 airbag complaints are the passenger occupancy sensor deciding an adult is a child and switching the airbag off half the time, and five crashes without deployment. One more: recall 10V283 replaced a steering-column roll connector whose cracked wiring could kill the driver airbag, horn and cruise. Sit in the passenger seat, start the car, and watch the airbag-off light.

Repair cost: $0 with the recall — verify it was performed; $300–$900 for a passenger occupancy sensor

6-speed manual cars: a missing lubrication hole and a parking brake that may not hold (two recalls)Medium

The manual Legacy avoids the CVT but carries two recalls of its own. Recall 10V326 covers 6-speed cars built April 28 to June 23, 2010, where a programming error left out a lubrication hole inside the gearbox; the warning is a groan that grows until gears are damaged, and dealers drilled the hole and replaced parts if needed. Recall 18V626 covers 2010–2014 manual Legacys whose electronic parking brake actuator may not engage, so a car left in neutral can roll; the actuator is replaced free. One manual owner in this record describes a bang at idle in reverse with the clutch down. Check both on the VIN, drive it in every gear listening for a groan, and set the parking brake on a slope with the car in neutral.

Repair cost: $0 with the recall — verify it was performed; $1,500–$3,500 for a manual gearbox rebuild if the groan was ignored — around 58% of what this car is typically worth

EJ25 head gaskets on the 2.5i — coolant loss and overheatingMedium

The 2010 2.5i still uses the EJ253 flat-four, the engine with Subaru's long-running head gasket reputation, and one owner in this record is on repeat gasket and radiator repairs. It is not a large share of this year's complaints, but it is a four-figure repair when it comes, and it shows up as an overflow tank that needs topping up, a sweet smell after a drive, or the temperature gauge creeping on a hill. Check the coolant level cold, look for white crust around the tank and hoses, and ask a shop to sniff the overflow for exhaust gases. The 3.6R six and the 2.5GT turbo are different engines with different habits.

Repair cost (estimate): $1,500–$2,800 for head gaskets at an independent Subaru shop — about 47% of what this car is typically worth

Smaller recalls: wiper motor overheating, puddle-light short, remote-start fobs, replacement ignition switchesLow

Four more free fixes worth confirming on the VIN. Recall 16V694 replaced a wiper motor cover on 2010–2014 Legacys that could overheat and stop the wipers in the rain. Recall 12V602 added a fused harness to the door-mirror puddle lights, where moisture could short the circuit — one of the twelve electrical complaints here is a fire. Recall 13V061 replaced Audiovox remote-start fobs that could start the engine by themselves. Recall 19V297 covers cars fitted with a replacement mechanical ignition switch that could turn itself off while driving; it only applies if the switch was ever swapped. None costs anything; all take a minute to check.

Repair cost: $0 with the recall — verify it was performed

Walk-Away Red Flags

✗Shudder or a dipping tach in the last few mph of a stop, especially uphill
✗Any Takata campaign still open on the NHTSA VIN lookup
✗Passenger airbag-off light flickering with an adult in the seat
✗Coolant overflow tank below the line, or a sweet smell at the front after the drive
✗Groan from a 6-speed manual that rises with road speed in gear

Good Signs

✓Torque converter or CVT replaced on a dated invoice, ideally under Subaru's extended coverage
✓Every Takata inflator campaign shown closed on the NHTSA VIN lookup
✓Ten smooth stops from 30 mph with the tach steady at idle each time
✓Head gaskets already done at a Subaru specialist, with the receipt
✓Parking brake that holds the car on a slope in neutral
