I realize that unless you work in the industry, most at a dealership, or buy a new car every year, you may not be aware of all the new technologies, but this one is really new to me (and I suspect maybe a little BOGUS).
I pulled out of my driveway yesterday (2014 Subaru Legacy 2.5 H4 engine, CVT) and about a half mile from the house, I noticed the brake light blinking. Along with it, the traction control icon was on steady, the cruise control icon was blinking (CC off) and the check engine light on steady. I turned around and went home. According to the owners manual, the blinking brake light meant a defect in the electronic parking brake. The car may not be safe to drive.
I pulled the code P1449 which according to the code reader means “air filter clog”. The car has 33k on it and I changed the filter at 30k. I pulled the snorkel and checked it and it was clear.
Since it is under warranty, I called the dealer to schedule the repair. I asked the service advisor if it was safe to drive and she told me that the blinking brake light was only to get my attention that the check engine light was on. BTW, the parking brake seems to be working just fine, setting and releasing normally.
I have sent an email to the Subaru technical center at MySubaru.com to see what they say. I’ll let you know when I get a response.
