Subaru technical service bulletin 09-66-16 for 2015-2017 Subaru Outback and 2015-2017 Subaru Legacy.

Bulletin number
09-66-16
Component
Engine and engine cooling: exhaust system
Summary
This bulletin announces a change in the production procedure for the rear muffler assembly. Spot-weld locations securing the outer shell portion have been changed to improve overall rigidity. A gap may develop at the spot welded seam as a result of repeated thermal shock (heating / cooling) which occurs during normal use. The gap does not create an exhaust leak. In some cases, a rattling sound from the muffler may develop.

Owners of these vehicles have filed 187 complaints in the engine category.
