The 2001 Outback is mechanically solid in chassis and drivetrain layout, but the 2.5L EJ25 engine is notorious for head gasket failure — budget for this repair if buying used. The 4-speed automatic (4EAT) has its own cooling and mount issues that compound over time.
Head Gasket Failure (2.5L EJ25 only)
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: external oil seepage at block/head junction, white smoke or coolant smell from exhaust, overheating or coolant loss with no visible leak, milky oil on dipstick if internal breach
Fix: Both head gaskets, resurfacing heads, timing belt/water pump/seals while in there. 12-16 labor hours at an indie shop. The 3.0L H6 does not have this issue.
Estimated cost: $2,000-3,000
Transmission Oil Cooler Line Corrosion
Common · high severity
Typical onset: 100,000-180,000 mi
Symptoms: ATF leaking near radiator or under engine, transmission running hot, low fluid level causing slipping or delayed engagement
Fix: Replace corroded steel lines (OEM or aftermarket stainless). Often done alongside a fluid flush. 2-3 hours labor.
Estimated cost: $400-700
Rear Differential Carrier Bushing Wear
Occasional · medium severity
Typical onset: 120,000-200,000 mi
Symptoms: clunking from rear on acceleration or deceleration, vibration at highway speed, visible sag or misalignment of rear diff
Fix: Replace carrier bushings; some techs install aftermarket solid or polyurethane replacements. Requires subframe drop. 3-4 hours.
Estimated cost: $500-900
Transmission Mount Failure
Common · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: excessive engine rock when shifting or accelerating, clunk when shifting into drive or reverse, vibration at idle
Fix: Replace rear transmission crossmember mount (often called the 'pitch stopper'). 1-2 hours labor.
Estimated cost: $200-400
Fuel Pump Failure
Occasional · high severity
Typical onset: 150,000+ mi
Symptoms: no-start or intermittent no-start, engine stumble or cut-out under load, whining noise from rear seat area
Fix: Drop fuel tank, replace pump assembly. NHTSA recall covered some units; check VIN. 2-3 hours labor.
Estimated cost: $600-1,000
Cruise Control Cable Seizing (Recall)
Rare · high severity
Symptoms: cruise control sticks on, throttle does not return to idle when released
Fix: NHTSA recall for cable replacement. Should be free at dealer if not already completed. Verify recall history.
Estimated cost: $0 (recall)
Owner tips
If buying a 2.5L, assume head gaskets need doing unless proven otherwise with service records — factor $2,500 into your price negotiation.
Change ATF every 30k mi and inspect cooler lines annually; caught early, corrosion is a $200 repair instead of $3,000 transmission replacement.
Timing belt is due every 105k mi — always do water pump, all idlers, and cam/crank seals at the same time.
A capable, practical wagon let down by the EJ25 head gasket design; if that's been done or you're buying the H6, it's a solid 200k-mile vehicle.

Airtex Products LP (Airtex) is recalling certain model E8598M, E8518M, E8600M, E8596M, and E8597M fuel pumps manufactured July 26, 2013, and July 29, 2013 and used as aftermarket replacements on Subaru Baja's, Outback's and Legacy's. The affected fuel pumps were sold or installed into the aftermarket applications on or after July 26, 2013, and may may leak fuel from the base of a fuel line connection when the gas tank is full.
Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: Airtex will notify owners, and will replace the fuel pump, free of charge. Recall is expected to begin on January 2, 2014. Customers may contact Airtex at 1-800-880-3056. The recall is expected to begin during January 2014. This recall is being conducted by Airtex, not by Subaru.
VEHICLE SPEED CONTROL:CABLES · 04V128000
2004-03-16
ON CERTAIN PASSENGER SEDANS, WAGONS, AND SPORT UTILITY VEHICLES, THE CRUISE CONTROL CABLE COULD COME OUT OF ITS TRACK ON THE CRUISE CONTROL LEVER AND LODGE ON THE CONTROL LEVER TAB WHEN THE ACCELERATOR PEDAL IS RELEASED. IF THIS CONDITION OCCURS, THE THROTTLE WILL NOT RETURN TO THE IDLE POSITION AND WILL REMAIN IN AN OPEN POSITION.
Consequence: IF THIS OCCURS DURING VEHICLE OPERATION, THE DRIVER COULD LOSE CONTROL OF THE VEHICLE, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSTALL A CRUISE CONTROL CABLE RETAINING CLIP TO THE CRUISE CONTROL LEVER TAB ON THE THROTTLE SHAFT IN ORDER TO PREVENT THE CRUISE CONTROL CABLE FROM COMING OUT OF ITS TRACK. OWNER NOTIFICATION BEGAN ON APRIL 12, 2004. OWNERS SHOULD CONTACT SUBARU AT 1-800-782-2783.
SUSPENSION:REAR · 03V153000
2003-04-22
THIS RECALL APPLIES TO CERTAIN PASSENGER VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, KENTUCKY, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, VIRGINIA, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA. CERTAIN REAR SUSPENSION SUBFRAME COMPONENTS WERE PRODUCED WITH POOR PAINT QUALITY WHICH, AFTER CONTINUED EXPOSURE TO CORROSIVE ROAD SALTS FOR A PERIOD OF SEVERAL YEARS, COULD RESULT IN RUST-OUT OF THE COMPONENT AND POSSIBLE BREAKAGE OF THE SUBFRAME.
Consequence: IF SUCH BREAKAGE OCCURS WHILE THE VEHICLE IS BEING OPERATED, CONTROL OF THE VEHICLE COULD BE AFFECTED, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL CLEAN AND RUST-PROOF THE REAR SUSPENSION SUBFRAME. OWNER NOTIFICATION BEGAN JULY 14, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT SUBARU AT 1-800-782-2783.
POWER TRAIN:AUTOMATIC TRANSMISSION · 02V282000
2002-10-30
CERTAIN SPORT UTILITY AND PASSENGER VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS WERE PRODUCED WITH AN IMPROPERLY MANUFACTURED TRANSMISSION PARKING ROD. WHEN THE TRANSMISSION SELECTOR LEVER IS PLACED IN THE "P" (PARK) POSITION, THE TRANSMISSION PARK MECHANISM, THAT IS INTENDED TO HOLD YOUR VEHICLE, MAY NOT ENGAGE.
Consequence: THE VEHICLE COULD THEN MOVE/ROLL WITHOUT PRIOR WARNING, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE AUTOMATIC TRANSMISSION PARKING ROD ASSEMBLY. OWNER NOTIFICATION JANUARY 8, 2003. AN INTERIM OWNER NOTIFICATION WILL BE SENT DURING NOVEMBER 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT SUBARU AT 1-800-782-2783.
