Never have heard that on mine. Let us know what the dealer says.
How's your dash cam setup? I'm curious about that...
I have a Lukas LK-7900 dash cam, it is Korean made (Much better then Chinese). It was the most inconspicuous of the quality dash cams. 1080P, Excellent day video, good night video, accepts 128GB SD Card(largest I've seen), records in different files for parked/motion, Driving, & Event (G-sensor marks the clip by the parameters you set).
I also have it hooked up to a power source that will shut off after a set period of time 6hrs-infinity or until the vehicles battery drop below a certain level.
My first cheap $40 Chinese camera came in handy when someone hit and ran my '11 F250 at a gas station. I poped the card into the laptop and showed the cop exactly what happened, guys face, plate etc. The Cop was blown away.

I also put an Olympus Polarized 37mm Lens on it as well, to cut back on glare from the dash reflection.
