My 2016 legacy battery died and the car would not unlock with the key. So I went through the trunk.I replaced the battery with a group 34. I then called Subaru to see if they would cover having a tech see why the door would not unlock with the key, after explaining what happened they told me to scan a copy of the battery sales receipt and send it to them they also called my dealer of choice to check on the door and do battery update, So I received a refund for the battery and had everything else taken care of. I had 44,000 and was out of warranty. GREAT CUSTOMER SERVICE!!!!
