What's going on with the textures in the City Vehicles Demo?

Hi, I am trying to learn how they did the vehicles in this Unreal Demo, but as soon as I open the vehicles that have like different colors, then the textures start getting all weird. If I move the camera then they start shifting to the next panel. Same thing happens with the Bus and the Van. This is out of the box. Can someone please let me know what is wrong here?
