Hmmm . . . I only park in the garage and it happens daily and has increased over time.Yup, mine did. I brought it into Toyota service and they didn’t find any dust or debris. They said it’s likely because there is some condensation from being parked outdoors overnight. I’m here in Seattle and it was warm with some humidity and cooler at night. I’m inclined to believe them since it doesn’t seem to happen when I park in my garage.
