I have a 03 Odyssey. I parked in front of the house after a 100 mile uneventful trip. It was raining. relevant? When we came out in the morning to leave for church we found the car full of dust. The windows were closed and the yellow/white dust came from the dash area and covered the whole interior, heaviest in the front. There was evidence of dust in the vents. What happened? An airbag discharged in the dash without deploying? Evil Pixies scattering dust? Late Halloween Trick? We gave out candy! Any ideas out there?
