I've had my 2015 outback for 3 years now (2020 now) i have had to replace the battery every year. the first year i believed it was time for a new battery, within 6 months my car died while i was driving into a parking lot. the entire electrical system shut down and i had to manually move it. my mechanic took apart my engine and discovered loose seals that had allowed many parts to rust over including broken brackets and a torque converter. warranty won't cover any rust but did cover the $84 broken seal. i spent close to $3,000 on repairs and a new battery then. i was initially quoted from the dealership $6k. it has been 11 months and i left my car alone for 3 days and the battery is completely dead once again.
On sept.27th, 2015, the liftgate opened on its own. many times the lights ,one at a time, over the mirror, will turn on and be hot to the touch when i get into the car after being out of car for hours or over night.the liftgate is a recurring problem,as are the lights.also, the bluetooth tells me i am calling myself frequently.electrical problems?? once the liftgate opened while the car was in motion. i have notes on dates & times
