2016 Subaru Outback-I've never had a problem with a fuel door. Pin is retracting just fine, but door doesn't want to open (maybe not enough spring tension?) Any good fixes? Can Subaru fix it (i.e. warranty the door/spring)? It looks like this is a pretty simple assm, can it be popped out and lubed? Potentialy stretch/bend the spring to increase opening force? Thanks!
