2001 Subaru Outback Problems

What owners report

Owners of the 2001 Outback most often report two things: a strong gasoline smell inside the cabin in cold weather, and premature brake pad and rotor wear, sometimes with poor braking from a cold start. A smaller but recurring group of complaints describes corrosion-related failure of the rear subframe at high mileage, plus head gasket and other engine work on the 2.5L engine.

1. 1
   Fuel system

   Fuel smell in cabin during cold weather

   • 26 complaints (15%)
   • median 84,900 mi at 9.6 yrs old (21 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $400 (median of 9 quotes)
   • filed 2003–2016

   Owners describe a strong gasoline odor inside and around the car once outside temperatures drop to freezing or below, often strongest near the intake manifold or the fuel lines under it. Some report the smell works into clothing, and some note headaches or nausea; a few say switching the heater to recirculate reduces it. Complaints describe hose clamps and flexible fuel hoses being tightened or replaced, sometimes repeatedly, and dealers sometimes telling owners the condition was common or that no leak could be found. One complaint describes fuel escaping from a loose clamp onto the exhaust manifold. Mostly reported in cold weather, often from roughly 50,000 to 130,000 miles.

   What to check: Start the car from cold on a cold morning and smell inside the cabin and near the intake manifold; ask whether the fuel hose clamps and lines under the manifold have been serviced, and have a mechanic inspect them for weeping or looseness.

   “2001 Subaru legacy Outback. Fuel vapor smell in cabin when temperatures fall below freezing. This has been a persistent problem for the three winters we have owned the car. This fall I found several comments online which prompted me to tighten the hose clamps on fuel lines running to/from the engine compartment fuel filter. This seemed to help until the last 2-3 days when we experienced prolonged temperatures of 0 to -15f. …”

   NHTSA complaint #10380087, filed 2011-02, 82,800 miles

   “I own a 2001 Subaru Outback, that when the weather gets cold, somewhere at and below 30 degrees, I get a gas odor in and outside the car. I have researched this on the internet and found that this is an *extremely* common problem with the car's gas lines and that Subaru is only acknowledging the issue on 2002 and newer models. Have you researched this issue before and can you tell me why no recall on 2001s was ever done? Thank you.”

   Suspension

   Rear subframe corrosion and fracture

   • 14 complaints (8%)
   • median 157,000 mi at 13.9 yrs old (13 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2003–2019

   Owners describe rust-through of the rear subframe and suspension components, in some cases found during routine service, and in others discovered after the rear of the car stepped out or a tire tilted inward. Several complaints say the anti-rust treatment from an earlier safety campaign had been applied but the frame still rusted through later. Dealers and the manufacturer are described as declining further assistance once the campaign repair was on record. Reported mostly from about 100,000 to 210,000 miles, typically on older cars in winter-salt regions.

   Recall 03V1530002 related service bulletins

   What to check: Put the car on a lift and inspect the rear subframe and its mounting points for flaking rust or perforation, and ask whether the rear suspension campaign repair was performed and when.

   “On sunday 29 2015 at 12.30 am .. My son was driving and a loud noise was coming from under the car . He had some trouble to turn and stop on the side. He did it ,we had to tow the car. The s arm broke subframe broke off. Was all rusted ..”

   NHTSA complaint #10702984, filed 2015-03, 180,980 miles

   “I was driving on I-84 in ct when my passenger side rear tire blew. The car fishtailed but I got it slowed down and over to the shoulder without getting into an accident. When the garage put the car up on a lift it was determined that the rear subframe had broken right where the upper control arm connected to it which allowed the tire to lean in towards the body of the car where it rubbed against the body, heated up and then ruptured. These tires had just been installed 3 days earlier. …”

   Brakes

   Premature brake pad and rotor wear, warped rotors

   • 29 complaints (17%)
   • median 36,000 mi at 4.2 yrs old (19 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2002–2015

   Owners report front pads wearing out at low mileage and rotors warping, producing shaking through the wheel and front end when braking, especially from higher speeds. Complaints describe pads and rotors replaced or resurfaced more than once, and dealers attributing the wear to driving style or to road salt and corrosion. Some owners also describe the brakes feeling hard or ineffective on the first application after a cold start in sub-freezing weather, returning to normal after the car warms up or after pumping the pedal. Wear complaints appear from under 15,000 miles up to about 60,000; the cold-start braking concern is reported in sub-freezing conditions typically between 30,000 and 110,000 miles.

   What to check: Have the front pads and rotors measured and check for pulsation during a highway-speed brake application; ask for service records showing how often brakes were replaced.

   “I have a 2001 Subaru Outback vdc. Since purchase I have had repeated problems with warping of the front brake rotors. The rotors have been turned twice, then replaced by Subaru in april 2003. The rotors have now warped again and are no longer under warrantly. This condition leads to uncontrollable wheel and front end shaking when braking at high speeds. There have been numerous other complaints for this vehicle.”

   NHTSA complaint #10078784, filed 2004-06, 47,000 miles

   “Front brake pads wore out at less than 36,000. Dealer replaced the pads under the warranty. Come to find out the rotors are warped too. We did not realize it until a little over 36,000 miles. Dealer will not fix rotors under warranty because we brought for service after warranty expired. A little research has identified that we are not the only people with this problem on this car. We are not at all hard on the brakes either. …”

   Vehicle speed control

   Throttle sticking or unintended acceleration

   • 11 complaints (6%)
   • median 46,500 mi at 4.3 yrs old (10 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2002–2014

   Complaints describe the engine holding speed or continuing to accelerate after the pedal is released, including with cruise control engaged, and in some cases braking not immediately reducing speed. Owners report the throttle cable being replaced and the problem not returning, and some describe the engine surging at very low speed in parking situations. Some complaints note that dealers could not duplicate the condition. Reported across a wide mileage range, from very low mileage up to about 150,000 miles.

   Recall 04V128000

   What to check: With the engine off, work the accelerator pedal and check that the cable moves freely and returns fully; ask whether the cruise control cable campaign repair was completed.

   “We have a 2001 Subaru Outback with the h6 engine. When going very slowly, such as parking in the garage, the engine will suddenly surge. You must keep one foot on the brake to prevent a sudden unintended acceleration. I have been told by the dealer that this is just the way it is with the computer control and the h6 engine. I have not had an accident , but it is a potential hazard. A sudden lurch could damage another vehicle in a parking lot or a person in front of the car. …”

   “This is graphic evidence of what happens when someone like Subaru 'forgets' to fit a $1 spring clip. The throttle probably stuck at around 3/4 open as she had just been traveling up a steep hill less than 2 miles from our house. The road then dips down and goes into a series of s bends, she left the road doing about 80mph and hit a tree 5 foot up in air from the road's surface. …”

   Engine cooling

   Head gasket leaks and engine noise on 2.5L

   • 30 complaints (18%)
   • median 83,000 mi at 7.2 yrs old (22 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $865 (median of 8 quotes)
   • filed 2002–2016

   Owners of 2.5L cars describe head gasket leaks requiring repair, sometimes followed by further engine work, and a cold-start rattle that fades as the engine warms. Complaints describe dealers calling the rattle a normal characteristic of the engine, and owners paying for gasket repairs out of pocket. Gasket repairs reported from roughly 30,000 to 105,000 miles; the cold-start rattle noted around 90,000 miles.

   1 related service bulletin

   What to check: Check for coolant and oil seepage at the head gasket area and any oil smell on the exhaust, listen for a rattle on a cold start, and ask for records of head gasket or timing belt work.

   “I have gone through one head gasket on jan 2003. The head gasket went out in dec of 2003 and the whole engine had to be replaced. In january of 2004 I had the overhead camgaskets go out on the car as well as the the oxygen sensor. I have had more issues but it would be a small book. Subaru has been relativly unresponsive even after many phone calls and letters to my concerns. Every part was replaced however there seems to be a poroblem with my new engine since there is now an investigation within Subaru. …”

   “2001 Subaru Outback at 90k after 2.5 engine is started it rattles like the valve lifters are not getting oil lubrication. It last for about 10 minutes or until the engine temp gauge is in the normal range. It does this when the engine has been sitting more that 8 hours without starting. Changing of oil in crankcase, did not change the rattling sound. …”

Buying note. Look closely at rust on the rear subframe and at brake condition, since these are the most frequently reported concerns on this model year, and confirm any open safety campaign work was completed. On 2.5L cars, ask for head gasket and fuel line service history and check for a cold-weather fuel smell before buying.
