hi there i do like this particular truck but when i go to mercedes benz dealers to get the truck on customisation side of it when i go into the interior i find that the steering wheel has shrunk , it doesen`t turn when steering plus the indicator levers dont seem to be showing and the handbrake lever when operating seems to go throught the air vent also one of the wipers is half missing and to top it off also when in customisation screen the front and formost back wheels seem to be blackened out is there a fix for these problems and if so when will it happen
