2003 Subaru Outback Problems

What owners report

Owners of this model year most often write about two kinds of problems: a head gasket that starts seeping oil or coolant and a rear strut that rusts through in states that salt their roads. Airbag inflator recalls also come up often, mainly because parts were unavailable for a long time. Many reports arrive in the 60,000-100,000 mile range, and several appear tied to cold weather or winter road salt.

1. 1
   Engine

   Head gasket leak (oil or coolant seep)

   • 11 complaints (12%)
   • median 81,273 mi at 7.8 yrs old (10 state mileage)
   • filed 2007–2017

   Owners describe a burning oil smell after short drives, coolant that disappears without an obvious puddle, and overheating while driving or idling. Some report the air conditioner stops cooling or the coolant reservoir runs empty with no visible leak. Complaints say the dealer or an independent shop identified the head gasket, and in some cases only one side was replaced under warranty; others report no assistance from the manufacturer. Reported from roughly 37,000 to 127,000 miles, often noticed as a smell rather than a sudden failure.

   What to check: Ask whether the head gaskets have been replaced and when, then look for oil residue or a sweet coolant smell around the engine and on the exhaust. Watch the coolant level over a few weeks of normal driving.

   2 excerpts from owner complaints in NHTSA records

   “My 2003 Subaru Outback had a bad airbag inflator and has also blown the head gasket several times, requiring it to be rebuilt three times. While I love my Outback, I wonder if I will want to buy another one. Being stranded by my car and having to take the bus in the winter time was very difficult as was hauling groceries on the bus in a rolling suitcase while awaiting repairs.”

   NHTSA complaint #11032558, filed 2017-10, 131,000 miles

   “After smelling leaking oil for many months, my mechanic confirmed that the head gasket is leaking. Oil is leaking down onto the exhaust creating a constant burning smell. I contacted Subaru and they are unwilling to address this in any way, despite the fact that the engine has been meticulously maintained and serviced.”

   Suspension

   Rear strut rust-through and spring mount failure

   • 7 complaints (8%)
   • median 86,000 mi at 8.0 yrs old (7 state mileage, few)
   • filed 2008–2017

   Complaints describe a loud snap followed by the rear of the car dropping, with the lower spring mount rusted away from the strut. Owners in states that use road salt year-round report this on vehicles with well under 100,000 miles. Some say the dealer or manufacturer declined assistance because the vehicle was not covered by the front and rear suspension corrosion recalls. Mostly reported between about 60,000 and 87,000 miles on cars driven in winter-salt states.

   Recall 03V153000Recall 03V2320002 related service bulletins

   What to check: Inspect the rear struts and spring mounts from underneath for heavy flaking rust, especially on a car from a salt-belt state, and ask whether either strut has been replaced.

   “I am the original owner 2003- current/2013. Accelerating from a stop light in traffic, I heard a very loud snap and the right rear side of my car fell to within an inch of the right rear tire. I was able to drive the car, slowly, to a Subaru specialist. I was told the right rear strut rusted and broke after only 7 years and less than 87k miles. I was forced to replace the strut assembly since this was a safety issue. The car has always been driven year round in maine and new hampshire. …”

   NHTSA complaint #10510665, filed 2013-05, 87,000 miles

   “Accelerating from complete stop, I heard a loud snap from the right rear wheel well. Upon inspection by an ase mechanic, it was determined that the right rear strut and assembly had rusted out and broken on a vehicle with only 81,000 miles on it. The car is located in a very high salt use state, maine, and this seems to be the exact type of rusting and breakage problem other Subaru's have previously been recalled for in high salt use areas.”

   Engine cooling

   Stalling or surging at stops

   • 5 complaints (5%)
   • median 10,000 mi at 0.5 yrs old (5 state mileage, few)
   • filed 2003–2011

   Owners describe the engine quitting when slowing for a stop or a turn, sometimes restarting immediately and sometimes needing a wait. Several say multiple dealer visits could not reproduce or diagnose the problem, while a few reports describe surging forward after stopping that was traced to carbon buildup in the throttle housing and idle control valve. Reported from a few hundred to about 40,000 miles, occasionally in hot weather.

   Recall 02V240000

   What to check: During a test drive, come to several slow stops and note whether the idle dips or the car lurches. Ask whether the throttle body and idle control valve have been cleaned.

   2 excerpts from owner complaints in NHTSA records

   “The vehicle surged after coming to a stop when the brakes were applied. The dealer reset the computer, but could not duplicate the problem. The vehicle surged numerous times after that, always after coming to a stop. The consumer had taken the vehicle to a different dealer, who suggested the computer be refreshed. The vehicle had not surged since then.”

   NHTSA complaint #10040053, filed 2003-10, 1,300 miles

   “Consumer states that while driving and without warning the vehicle will stall. The dealer was notified. When braking to stop or make a turn the vehicle will stall. The consumer was told that thee are other vehicles (same make/model) with the same problem.”

   Vehicle speed control

   Throttle or cruise control sticking

   • 5 complaints (5%)
   • median 37,000 mi at 2.6 yrs old (5 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2004–2010

   Complaints describe the accelerator pedal sticking or the engine holding high rpm after the pedal is released, and cruise control that would not disengage at highway speed. Owners report using neutral or the key to stop the car, and several say the dealer could not duplicate the condition; one complaint attributes it to a floor mat. Reported from very low mileage up to about 85,000 miles, sometimes on cold mornings.

   Recall 04V128000

   What to check: Check that the throttle linkage and cruise control cable move freely and return fully, confirm the recall work for the cruise control cable was done, and make sure floor mats are the correct type and secured.

   “Accelerator on vehicle stuck on interstate highway. Tried to put vehicle into neutral however RPM's spun to 7000. Had to eventually turn car off in drive after riding approximately 2 miles with both feet on brake. Dealership unable to identify any issues, and told me it'll probably not happen again”

   NHTSA complaint #10122351, filed 2005-05, 70,000 miles

   “Throttle stiff when first opened. Rpm's will jump when throttle pressed. Not smooth at all. Hard to regulate speed, without bucking. Dealer says this is normal for computer regulated car. Baloney.”

   Air bags

   Passenger airbag inflator recall and parts delays

   • 19 complaints (20%)
   • median 102,610 mi at 13.3 yrs old (6 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2004–2018

   Owners report being told their vehicle is covered by the passenger airbag inflator recall but that replacement parts were not available, sometimes after multiple visits. A few complaints describe airbags that did not deploy in a collision, and others simply ask how to confirm the recall was completed. Reports span low to high mileage; several come from owners of long-owned cars checking recall status years later.

   What to check: Check the VIN for open airbag recalls and ask for documentation that the passenger inflator replacement was actually performed, not just scheduled.

   “Takata recall: the passenger side air bag needs to be replaced. Subaru have told me that they do not have the parts needed for this recall. My wife and I are over seventy and I need to use this vehicle with her in the passenger seat. If replacement is currently impossible, Subaru needs to provide me with a loaner.”

   NHTSA complaint #10898770, filed 2016-08, 140,000 miles

   “Takata recall this may pertain to the takata air bag recall. My wife and I were in a t-bone type collision at ~45 MPH and the driver and passenger airbags failed to deploy in our 2003 Outback. When I check the VIN I did not see any open recalls nor did I ever receive any recall notifications for the car.”

   NHTSA complaint #10823291, filed 2016-01, 160,000 miles

Buying note. A pre-purchase inspection by a shop familiar with Subarus is worth the cost on this model year, focused on head gasket seepage and rear strut rust. Confirm that any open airbag inflator recall has been completed, and expect that a car from a winter-salt state may need suspension work.
