DS7 Panoramic Camera issue

Hi,

My brand new DS 7 HDI (just got it last week from dealer) started yesterday evening to have an error of 360 cameras. First the front camera was not working displaying a camera icon with an exclamtion point. Afterwards, when I parked at home I noticed the rear one also stoped woring, the screen showed a car icon with blacks where normaly the camera images woould show.
I left the car for 30 mins and on my return I noticed the rear camera started working again but the front one did not. As of now (24h later) the situation is unchanged. Night vision works fine, no error messages anywhere and no new software updates.
I am puzzeled about this happening in a brand new car, next week I have an appointement to the dealer.
Anyone had any issues similar to mine?
