Repeated dead battery 2015 Subaru Outback
The battery on this car has gone dead at least 7 times; most of them with no know cause as in a light left on. On one occasion, we had the hatch and doors open for several minutes as we prepared to go on a canoe trip.
Now, we start the car before loading. Turn everything completely off when we stop driving such as lights, seat warmer, radio, etc. I fear that something continues to run and drain the battery when the car is not running.
There are several threads here on CG's regarding this issue. You might want to look at them.
Good Luck! Subaru does not want to acknowledge there is an issue with parasitic drain. I've had it 6 times in 20 months. Car has been at two different dealerships for almost 6 total weeks - no resolution. Case opened with Subaru America - also not much help.
Brand new 20019 Outback. Had it for 2 weeks. Sitting in the garage looking so pretty with a dead battery. Trying to charge it up now even though we're painfully aware that our 2018 Outback had the same problem.
Brand new 2019 Subaru Outback has a dead battery AGAIN after sitting all weekend. Less than 2000 miles on it. Wish I could go back in time and not buy it.
Dealerships don't seem to want to record (in writing) these parasitic drains and therefore there will be no record of them. I advise everyone who is experiencing this repeated, blatant flaw in the electrical system to open a case with Subaru America. I opened one and yes, you get the run around and no I didn't get resolution BUT at least there is now a record of the problem! Don't accept this - unreliability puts your personal safety at risk!
Subi3522 you are absolutely right. I am going to look up the Subaru America address and file a formal complaint in writing and certified. And I am making an appointment with my local Subaru dealer to look for a "Parasitic Battery Drain" - I am going to try get them to put that in writing. The other important thing is a formal complaint with NHTSA - here is the link. Everybody file there so they can't hide it: https://www- odi.nhtsa.dot.gov/VehicleComplaint/
Our 2018 Outback with 25k miles just had its 3rd dead battery event. After the second I talked to the shop at our dealer and was advised that running sequential short trips....like a day filled with errands and multiple start/stops will drain the battery. And that it takes a 20 minute plus drive to fully charge the battery. I bought a TACKLIFE jump start battery after the second event and it worked great to get started this time. I HIGHLY recommend getting one of these. There are several brands available for about $75-$100.
"...was advised that running sequential short trips....like a day filled with errands and multiple start/stops will drain the battery." Ridiculous. (1) It takes less than "a day" of errands for the problem to occur. (2) "a day filled with errands and multiple start/stops" is a PERFECT DESCRIPTION of the typical American car owning parent's life. Subaru either needs to build cars that can handle reasonable requiremets, or WARN CONSUMERS that its cars are unable to cope with them.
Jcjc1956 is exactly right..... It's ridiculous! Come on Subaru of America step up and be the Brand you used to be!
I put a group 34 800 CCA battery in my 2015 Outback from Costco ($95.00), fit fine. No problems since. Used a setting saver to switch them (about 18 dollars on Amazon) and all setting etc work fine.
I have left my 2015 outback at the airport twice for 5 days, both times it has died with no explanation. This really sucks not to be able to leave this vehicle.
Had my car sit in the driveway for almost 3 days. The car started up like a charm. Fast forward one month later I'm driving around running errands. Pull up to a store, turn the car off, go inside. I am back in less than 10 minutes, and the battery is dead. It makes no sense.
Once the original battery is 2 years old it probably needs to be replaced.
At the 30k mile service visit I asked that the dealership check any thing that might contribute to the "dead battery syndrome". Reviewing the work done the agent said they had made some software mods as the battery recharge logic was set wrong and the battery wasn't fully charging. That was 2 months ago and no dead battery since then.
As I have previously mentioned in this forum they replaced my entire CPU which did not resolve the problem. Then they replaced the entire dash cluster ($$$) which so far is working! I had rental cars for almost two months which Subaru of America paid for because my case was open for so long. The dash cluster was a major expense but cost me nothing because I had this case open.
i just talked with Subaru America about the dead battery issues - i have a 2016 subaru outback and on my 3rd battery. they said no record of any issues with battery problems or recalls, the person i spoke to (Jim) was condescending and said if i wanted to put a larger battery in, i could do it if i wanted - and that since the current battery is still working he couldn't help.
With our 2014 Outback we replace the OEM battery with a new, from Costco, group 25 battery. After several dead battery events we again replace the battery with a Costco group 34 which has near to twice the amperage storage of the OEM battery. So far so good. The group 34 fit the car without a problem. Andy in Astoria, Or.
It sounds like this problem is not the battery. We have had it in our subaru and our toyota matrix which both have after market remote start fobs...like having a tv that is plugged in and ready for a remote to fire it up. One solution to parasitic drain would be a master switch on the positive lead at the battery, a pain to open the hood to park extended periods, but it would work. Or you can just disconnect the battery. You'd have to use the key to open the door. Sounds like making sure the hatchback is closed after using the key fob to open the doors is a good idea. And filing a case with Subaru.
