What Owners Say
"rubber fuel vent hoses at gas fill pipe area deteriorated causing evap emissions system to trigger check engine light"
Anonymous, NJ (2001 Subaru Forester S 2.5-L 4 Cyl)"Engine light came on. Dealer repairs were ineffective and escalated in cost with attempted fix"
Anonymous, MA (2001 Subaru Forester L 2.5-L 4 Cyl)"the check engine light let to a major overhaul of exhaust system, costing over $1000. This happened soon after the clutch replacement, leading to the question "how much money should we put into a 14-year old car?""
Anonymous, NJ (2001 Subaru Forester S 2.5-L 4 Cyl)"had to replace both sensors"
Anonymous, CO (2001 Subaru Forester 2.5-L 4 Cyl)"To pass E-test after purchase(where E-test not req'd) a number of sensors and Cat .converter needed to be replaced. The check engine light has been an on going problem since purchase(as per previous owner)"
Gregory G., ON (2001 Subaru Forester L 2.5-L 4 Cyl)"catalytic converter failure"
Anonymous, NC (2001 Subaru Forester S 2.5-L 4 Cyl)"Check engine light is on, and mechanic says it is due to corrosion in emissions control system. Not worth fixing, he thinks"
Augustin P., MA (2001 Subaru Forester 2.5-L 4 Cyl)"Had to replace catalytic converter"
Gary H., OR (2001 Subaru Forester S 2.5-L 4 Cyl)"Check engine light: Knock sensor, catalytic converter"
Kenneth C., WA (2001 Subaru Forester 2.5-L 4 Cyl)"Check Engine light turned on. Replaced O2 sensor but light occasionally still comes on."
Anonymous, MD (2001 Subaru Forester S 2.5-L 4 Cyl)"Check engine light codes that indicate possible sensor malfunction"
Anonymous, VA (2001 Subaru Forester L 2.5-L 4 Cyl)"have had 3 oxygen sensors in the last 18 mo and 'check engine' reading just yesterday says I have an oxygen senor problem again"
Sandra M., OH (2001 Subaru Forester L 2.5-L 4 Cyl)"sensor not working so check engine light always on. Every time "check engine" light on it's $85 to $120 to get it checked. Have spent $$ and warning light always returns. Now they say it's the O2 sensor and about $400 to replace. not worth it. just i"
Curt R., OR (2001 Subaru Forester S 2.5-L 4 Cyl)"Check engine light keeps coming on. Goes off when completely fill with fuel but then comes back on as fuel level drops. Mechanics can't find problem or fix permanently"
Anonymous, CA (2001 Subaru Forester 2.5-L 4 Cyl)"O2 sensor failed"
Anonymous, NC (2001 Subaru Forester S 2.5-L 4 Cyl)"Pre- and Post-Coverter O2 sensors both failed during last year. New Catalytic Converter also failed during its warranty period and was replaced without charge"
Anonymous, IL (2001 Subaru Forester)"Replaced with Bosch, then had to use OEM to turn of CEL"
Robert S., WV (2001 Subaru Forester 2.5-L 4 Cyl)"Both upstream and downstream O2 sensors have failed, triggering repeated check engine lights. I do my own work, but replacing them seems unnecessarily difficult due to their placement, requiring removal of the catalytic converter to get at the downstream one"
Joe C., OR (2001 Subaru Forester L 2.5-L 4 Cyl)"Knock sensor failed."
David C., MN (2001 Subaru Forester L 2.5-L 4 Cyl)
