2011 Subaru Legacy not starting correctly in colder weather

Asked by Feb 10, 2015 at 11:41 AM about the 2011 Subaru Legacy 2.5GT Limited

Question type: Maintenance & Repair

My 2011 Subaru Legacy won't start correctly after sitting for the day in colder weather
(`37 degrees F).  The dealer has ruled out battery, starter and alternator.  It starts fine in
the morning when garaged (approx temp in garage ~45 degrees F).  After a day at work
(8-10 hours) sitting out in the cold, it struggles to start.  It takes multiple attempts.

I've thought about this off and on since yesterday and don't know what to tell ya. I could guess at it being a weak ground in the engine bay that gets worse with the cold but it is hard to say. I would recommend going to a legacy forum or NASIOC / ultimatesubaru or other forums and asking around. There are tons of good people on them that will hopefully be able to point you in the right direction. Best regards,

Use a vacuum gauge and check for an intake air leak.
