I had a very similar experience. Picked up the Bronco brand new from dealer drove it down the freeway and I saw this menu about charging came on and went off in seconds. Called dealer and they thought it was possibility just a glitch. It is never happened since, but in my opinion after much...
Sorry I didn't mean to really post my comment like that, what I meant was I put a graphene substance on my cars where nothing sticks to it in your case, all you would have to do is to blow off that dust.
I put Adam's Polishes Advanced Graphene Ceramic Coating - 10H Graphene Coating for Auto Detailing, 9+ Years of Car Protection & Patented UV Technology on my BS and mustangs to make my life a lot easier in my rides look pristine at all times.
