This Service Dept. has been generally very good since we bought our Outback in early 2016. Recently (January 2020) they found some bad wheel bearings when my wife went in for routine service and told them we had been "hearing a noise". We pretty well knew what the problem was but were testing them BECAUSE ...
... There was one episode in 2017 where they did not listen to my wife about a rattle in the muffler AFTER the car warmed up, then the service advisor told her there was no problem. (By the time they had gotten around to checking it, the muffler was cold.)
I went back for round two, ran the car until it warmed up enough for the problem to show up, and made the Service Manager listen to it. He went back to his office, got on the computer, and, miraculously, found a tech bulletin about there being one batch of mufflers in the right time frame with a bad internal weld. The lesson is two-fold: 1. They sent the woman away with an easy, no-effort answer. 2. The Service Manager did not bother to keep up with his tech bulletins on Subarus.
The other dealer in the north and west San Antonio areas (NOT the old North Park Subaru location) somewhat convenient to us is much worse about #1 above (see review elsewhere on this site), so we continue to use North Park Subaru at Dominion. BUT, the old phrase "Love 'em like a brother, watch 'em like a hawk" definitely applies at all times with dealership service departments..
