Brought my 2016 Outback in on Wednesday for a diagnostic on a mysterious clunking noise that I was hearing coming from the rear. The techs put it up in the air and inspected all the mounts, pivots, bushings, etc. Brought it down, took it for a test ride ... put it back up in the air, and looked at other things, brought it down and took it for another test ride ... pulled it back into a bay and started looking at other stuff. Finally they came and got me in the waiting room, and brought me out to show me what they found. The hood was up, and I'm thinking "Oh dear god no, not the engine. Please, not the engine." So I ask them, "Engine?", and they said "Yep, engine. Come have a look." Turns out one of the engine mounting bolts had rattled and vibrated its nut off, and backed out of the mount about halfway, which was causing the clunking noise. The tech tapped the bolt back in, chased the threads with a die to clean them up, and torque on a new nut. Problem solved. Best part is when they tell me that because of the way Subaru's mounting bolts are set-up, had the bolt come completely out, the engine would have pivoted on the two side-mount bolts like a see-saw, dropping the front of the engine to the ground. If this happened at pretty much any speed, it would likely have totaled the car. So yeah ... 5 stars. I'd give them 50 if I could..
