20000 mi Volume control on steering wheel works sporadically. Dealer said they couldn't replicate problem, so they couldn't fix what they determined wasn't broken.

98000 mi

US $15
Replaced headlight. Previously hadn't reported these. But this must be the sixth bulb I've replaced. I think it's a big issue for 5th Gen Legacies. And getting to the bulb is a royal PITA (through the wheelwell.)

Warranty extended on lightbulbs since bulb filaments break consistently. Had them changed during this time. 
24300 mi Fuse #34 blew. Problem was with dealer installed "puddle lights." Lights shorted out and fried the body control module. There is a recall for this problem. Dealer did not have the parts in stock to repair this known problem. Dealer replaced four puddle lights, wiring harness and added an in-line fuse under a recall. A short in the puddle lights caused the body control module to fail. That part was replaced under warranty. Car in the shop for six days.

C $15
L headlamps pigtail failed due to heat damage relating to poor connection. 3 headlamps replaced annually prior to replacement harness(aftermarket) so far so good.
