Poor Design/Quality
 I have had nothing but problems with my Armada since I purchased it new back in July. The two front doors rattle and move around over even the slightest bump. The dealer/manufacturer states that this is a characteristic of their $40K plus flagship vehicle. I have had the vehicle in for service too many times for creaks and rattles only to have the problems return. Stay away from this vehicle, it's poorly designed and of very poor quality.
