engine occasionally difficult to start after not being used for a day or so.
engine occasionally stumbles/misfires during startup. Mechanics ran diagnostic tests (first time they ran this test for 2014 vehicles), but found no problems.
rubber hood boot seal between turbo intercooler housing and air ductwork is warped, fits poorly.
Replaced rubber boot seal between hood and intercooler, and several fasteners which broke during replacement process.
Reprogrammed ECU per TSB to improve engine start-up.
replaced hood-mounted intercooler air diverter (rubber seals had become torn). 2nd time this part has been replaced
Engine was intermittently missing. Technician flashed ECU with new software update that addressed the problem.
Subaru recall to correct engine misfiring.
left side valves rattle/ping due to defective rockers. Subaru TSB estimates 10 hour repair time to replace/custom machine new valve rockers.
left side of engine valves, cam and rockers were badly worn. Required removal of engine, all its accessories and cylinder head to do repairs.
Catalytic Convertor Went Bad
Lagging throttle response. Hesitancy during acceleration (from a stop and during passing). ECU reflashed.
Forester 2.0L Turbo having an extended start of 3-5 seconds every few days. Dealer has no updates for the engine computer and did not observe any problems while it was in for an oil change.
CEL thrown during a hard start. ECU was reprogrammed with a fix for the issue
2014 Forester XT - Camshaft position sensor o-ring improperly installed from factory. Caused significant oil leak on drivers side of the engine. - Burning oil smell inside the cab alerted me to the problem.
Same camshaft position sensor was leaking oil.
Saw a spot of oil.
One other sensor, but I don't even remember what that was. The fix was to swap the sensor to the other side of the engine to see if the problem would follow the sensor.
Recall notice: Ignition computer was reflashed to solve a pre-ignition problem under hard acceleration
Engine loses oil at more than 1 qt per 2000 miles. It is difficult to correctly read oil level.
Excessive oil consumption (1 qt every ~2k miles). Dealer performed consumption test over 1200 miles, consumption deemed within Subaru spec. Continues to consume oil.
during a long distance driving, engine oil light on when drove at middle of nowhere. (Oil Level Gauge shows oil leaking) had to drive another 30 miles bought and added 1qt 0w20. light's off. before the engine oil leaking,found coolant lower minimum mark, sent to dealer, was told it's not a problem and refuse to add coolant. I spent 25 bucks and filled by myself.
Changed engine due to oil consumption problem. Used two quarts of oil in 2,800 miles.
Replacement engine burns one quart of oil every 3,000 miles.
I was driving about 70 mph on busy highway when suddenly engine turned off! I was able to steer car off road, turned car off. When I turned on ignition car started up and I drove away. Dealer could not find any codes to indicate problem.
Related to prev. problem where attempted repair didn't fix noise issue. This time, I drove w/tech & he confirmed noise. He put on lift & discovered sound attenuator in central exhaust pipe had prematurely broken up. Replacing pipe solved it.
Has begun burning oil bet. oil changes, ~1 quart in 4000 miles. According to the manual this is acceptable, having a oil light go on between oil changes is too much for me. Note there are 2 class action suits abt this engine & oil burning.
Oil low. Dealer refilled with oil and told to monitor the oil level for the next 1,200 miles to see if the car is using oil.
Return for oil consumption test. Results, car not consuming any oil over a 1,200 mile test.
Serpentine belt came off. New belt put on
Fuel cap left loose by attendant causing check engine light to come on. Would not reset after fuel cap was tightened
