Subaru Forester electrical problems

I've had to replace the battery three (3) times in a four (4) year old vehicle. I've had several calls to AAA for a jump start (to then get to Dealer to replace battery) and I had to purchase a rapid charger which I must carry in my car all the time in case the battery dies again. The problem with the battery began within the first year of purchase and has continued two times afterwards replacing the battery now 3 times Below I put the last time this happened. I've been stranded numerous times and I shouldn't have to keep jump starting my car. I've brought this concern to the Dealer (Sunset Subaru, Sarasota) and it is not taken seriously. In my opinion, this has been and continues to be a technical problem going back to the purchase of the vehicle in question.

My new battery completely drained over a weekend in my garage. I had AAA jump the battery and drove to their service center to check the battery to see if it was damaged. They said it was in great condition, no problems they could detect. A few days after the battery drain I found the passenger side window will not operate from the driver side console. I have an appointment with the Subaru dealership to investigate the problem. This is the second time I have had a complete battery drain on this vehicle. I am now on 2nd battery and there is only 18,867 miles on the vehicle. We could not find any reason for the drains.

The battery drains quickly if the engine is not running and the key remains in the ignition even for a short period of time. From what I can tell even if you shut off the car completely, you cannot leave the key in the ignition or something is still drawing power. You must physically remove the key from the ignition. The issue stranded my family on two separate occasions requiring a jump start. Once was late at night in a secluded area, the other in a parking lot. We have two other cars from different makes and have not had this issue. In one case the car was off in a parking lot with my wife waiting for 15 minutes. In the other my daughter was listening to the radio while parked for less than 10 minutes. This Forester has the stock radio with no after market mods. The Forester drives great and feels very safe in all other respects. We truly love the car. But I have to make sure that we do not park the car and leave the key in the ignition or the battery will die. I asked my mechanic to check the battery, but he said that the battery itself tested fine. Seems like this problem has been reported elsewhere. Thanks

The oem battery in this vehicle has failed Multiple times (dozens of times), upon sitting for a few days. Nothing in the vehicle was On, it was just sitting. A couple of times it was towed to the dealership in Bozemanwhere I bought it (Gallatin Motors) for diagnosis and repairs (bad/dead battery). The battery was replaced Once per Subaru's policy. Then I was on my own for repeated, totally unexplained DEAD battery upon trying to start the car after a couple/ few days/ nothing left on. I finally bought my own new recommended Interstate Battery after repeated dead out non starts. I bought a Duracell battery maintainer/ conditioner to install in my garage, which I use when the vehicle sits for more than 2 or 3 days to be sure the darn battery will start the car. It's obvious to me there's a parasitic battery drain in this smart car, but no one from any dealership will acknowledge/ has any advice about this! This is discussed in multiple online forums. I love the car and it's smarts, but not turning Dead Off after I'm finished driving it - and draining the battery making it impossible to start again without a jump - is totally not acceptable for a "vehicle."

The contact owns a 2017 Subaru Forester. The contact stated while attempting to start the vehicle, the vehicle would not start due to battery drainage. The contact stated that the battery had to be connected to a battery charger after each use. The contact stated that the check engine warning lights was illuminated. The vehicle was not diagnosed nor repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 22,375.
