ytqm Posted December 7, 2018 Share Posted December 7, 2018 There is a TSB on extended crank times for the 2015 Legacy. You may have to do a search on here to get the number of the TSB. Link to comment Share on other sites More sharing options...

plm42 Posted December 8, 2018 Author Share Posted December 8, 2018 OK, the reason I asked you to do that is to check and see if the fuel pressure is draining off. It should not drain off in a day but if the car sits for an extended period of time it will drain off somewhat. if the fuel pressure is draining off it means one of the following is true 1. bad check valve 2. bad fuel pressure regulator (if so equipped) 3. leaky injector (this would not likely be intermittent)I've heard of the outback having the same issue. In any case, I drive the car everyday, so I'd be hard pressed to diagnose a leak. Will try and follow up. Thank you!

CamaroSS2000 Posted December 18, 2018 Share Posted December 18, 2018 My 15' did this yesterday when leaving work, I turned the key and was a long extended crank time. It started but sputtered and died. It did that 3 time until finally starting. Temp outside was 34 degrees. This morning it was 25 degrees and started fine.

p21usa Posted December 18, 2018 Share Posted December 18, 2018 Here is the link to the latest service bulletin re: this matter. I will be bringing my 2015 2.5 engine Legacy in for this update on Friday. I replaced the 350 CC battery with a 550 today. https://static.nhtsa.gov/odi/tsbs/2017/MC-10125883-9999.pdf Link to comment Share on other sites More sharing options...
plm42 Posted December 21, 2018 Author Share Posted December 21, 2018 Hey guys, quick update. I got a check engine light yesterday and brought the car into the dealer. Turns out that the Active Engine Grill Shutters were stuck, filled with snow and sand (Fairly odd since I wash my car regularly, even during winter. Obviously, I haven't gone mudding with a legacy...) Anyhow, since the car was in, the dealer reprogrammed the Idle configuration and applied the alternator TSB. Will update if this solved all issues!

Norskie Posted December 28, 2018 Share Posted December 28, 2018 On our 4th Subaru and here in MN the OEM batteries start to have issues after the second winter. I'm sure we could squeeze another winter or two out of them. The last thing I want is my wife and kid stuck in a -15F walmart parking lot with a dead battery, so I replace the 390 CCA OEM battery with a 640 CCA battery at the first whiff of slow winter cranking. I can usually confirm a battery problem when I see starting voltage drop below 10v. We get about eight years out of non-Subaru batteries. Currently, Costco's $80 for a Group 3 Interstate battery seems the best deal. I still don't know why Subaru insists on putty crappy batteries in vehicles sold in cold climates. It's not like they saved much money or weight on an undersized battery. That and tires ... never had a car with as crummy tires from the factory as our Subaru's.

plm42 Posted January 11, 2019 Author Share Posted January 11, 2019 Washing car when cold can make the shutters freeze this time of the year. Damned if you do, damned if you don't I guess Anyhow, given the weather lately, I'm not sure that washing the car spews more water on it than just driving on the highway. In any case, just a quick update for you guys. Although I can see that the battery is weaker than previous cars I've owned, I haven't had any further issues with the battery/starter since the TSB. Voltages while driving or idling are around 14V at the OBD port and show 12.5V when the car is off. Dealer will look at the car's alignment during my next service.
