2016 Forester Touring -Battery Drain

[chasfish]

I have tried two dealerships and Subaru Corporate. No solution other than a gift card for 200$ which is no help at all. The last dealer who supposedly did the test called after 20 minutes and said there was no draw. The bulletin states waiting up to 55 minutes to insure that something else does not kick in. I just want it reprogramed or something that will allow us to be able to sell it. We have been sitting on the car for a year in September with absolutely no answers. So very frustrating. I just can't believe they cannot find a draw if I have gone through 5 batteries and if it sits for 3 days it is dead again. I asked for the reports and neither has them of the draw test, only telling me my battery is bad. The battery was less than a month old the first time and a few months old the second time.

Try replacing the battery sensor. I read in AAA magazine mechanic article this may be the cause of battery drain

As stated above, it's likely the Starlink trying to phone home with an obsolete, now dead and extint AT&T phone service. There's info about it all over the web.

Yes, that is what we know is going on but they are not helping at all. Two dealers have "tested" and said it is fine. We know it is drawing current and neither waited the allotted times on the Service Bulletin. We have dealt extensively with Subaru Corporate. We pull the DCM fuse and it is fine but obviously no one wants to purchase the vehicle with no working speakers or radio with the fuse out. We have researched and researched and my regular mechanic is at a loss. Meanwhile we are out a 9000 vehicle as no one wants to buy it with the issues it is having.

Thank you. It is worth looking into.

I think I saw a video on YouTube showing how to remove the Starlink module altogether. If it were my car, that's what I'd do ot have done. Ya gotta pull the head unit to do it because it's on the back of it or something. Attached to, but not part of the head unit.
