I recently did two long trips in my Forester without problem.
Fuel used was 9.7lit/100km.

On Sunday SWAMBO and I went for our standing coffee date and shopping.
I parked the Forester in the garage and went on with life.
Having not used the Forester since parking it on Sunday,
we were on our way out to a family dinner on Wednesday evening.
The rear door wouldn't unlock...?
I opened the driver's door and inserted the key.
DEAD electronics.
Nil.
Nada.
Kaput.

As I have an auto, I could not take the shift out of Park to push it backwards to access the engine compartment.
I squeezed my way in and used a battery tender charger for 12 hours.
I managed to get some life in the electronics, but not enough to even get a click from the starter.
So I had to get my local battery guy to house call with a new one.

I can't understand why a battery went from working perfectly to deceased...?  :-\

Any similar experiences?

Do you have a tracking system in the car?
What model? The H (and I suppose newer models) automatically switch off the inside lights if you leave a door open.

I have a 2013 SH - with the twin tailpipes.
I went for a drive today and all was good
Seems no damage done - I must just reset the clock.

And re program the settings on the radio I presume.
My battery lasted 6 years. But it worked hard as I sometimes have a fridge in it.

Hi

I had exactly the same problem last week. Went to shops the morning the afternoon the car was dead. Didn't even take charge!
Luckily the guy came out on a Sunday to replace it for me.

My money is also on tracker unit. One person discovered that his alarm that he had would use more power when near a wireless point.

Leave a light on and ours is dead the next morning.

Use the charger and it's working again.

Wife and kid forget about the lights.

Not very good for the battery, so I'm expecting it to die within the next few months.

So I had the battery replaced.

Everything okay...
...until I take a bike trailer I bought in for roadworthy.
Forrie would not start after the test!
Luckily I was parked in the same business centre as the battery shop.
Jump start and drive it to their place of business.
Forrie cuts out as I get there.
Brand New Battery is only producing 5-6volts.
Replaced under warranty only 3 days into the 24 month warranty period !
I will take it for a leakage test when everything opens again in January.
I suspect an un-notified tracking device.

No Sav, was the second battery already.
I think it's on it's way out.
Struggles when starting.
Even after a full charge.

Quite a process, sometimes you lucky and find it early but you need to put a amp meter on every fuse, then trace it. Check under your seats first for tracker but they hide them well.

On a side note, would they have put a tracker in a Subaru that never gets stolen?

Ah, okay. Those Panasonic batteries are really horrible things. I've switched to Varta Blue but they've also become ridiculously expensive now, so it's back to Sabat and it seems to be working just fine.
