So, I've got a 2012 Fit, 87K miles, no problems except replaced battery 18 months ago and air bag recall 12 months ago.

Last Spring, very occasionally, EPS and Airbag light would come on (along with lack of power steering) and the radio would cut out. Took it to my trusted mechanic when engine finally threw a code; bad relay, which he replaced.

Fast forward, car is doing this again, but no code. Doing it intermittently, but much more so than last spring. Happens while driving, but after the car has been driving for about an hour. And the other morning, after an hour's drive, it was doing it in 18 second cycles. Took it to the mechanic and he was unable to replicate it over the course of two days--one entire day sitting idling outside his garage, drove it home, back to the shop, etc. (He didn't charge me anything for this).

The car keeps running; power steering is unavailable; it's mostly annoying, but rather dangerous if you are in the middle of making a sharp turn and positively painful if you are parallel parking (I live in NYC).

He checked the grounds, there is no squirrel's nest or chewing damage in the wiring. He's unable to find anything untoward going on.

Any thoughts? Barbara
