NHTSA Complaint #11426058 — 2016 SUBARU OUTBACK

My Outback lost AC/Heat and even after repair at an Outback dealership, it still goes out intermittently. My car battery seems to drain for no reason at all, without any consistency to the drainage of power either. I have it looked at, and the dealership said there isn’t a cause and there isn’t anything that can be done. Back rear door doesn’t lock and unlock with the key fob designation; sets off the alarm when we don’t pay attention to it. Hatch door only lifts about 14 inches upon designation. Has to be manually lifted the rest of the way. Has been fixed once at a dealership, but since returned to the aforementioned diagnosis.
