Hi, topic says it all - got the passenger seat cushion recall work done this summer. Didn't have a passenger until recently - when I have a passenger in the seat, there is an intermittent loud humming noise coming from the passenger side dash. Anyone else have this issue? Is it related to the recall work? Quick fix maybe (hopefully)? Anyway, the Kiz is at 95k miles and doing well otherwise, third set of tires.

Sounds like an isolated seperate issue, i had that recal thing done too and i havent noticed any noises. Also seems like it would be a big pain in the butt to fix because theres just so much small intricate parts and i would assume it would be hard to diagnose it too :/ best of luck <3
