Yes, We are fighting with the dealership over this very issue. We have had a 2500HD in our fleet since spring. Recently, the rear end has started to sag so much that our headlights are blinding drivers in front of us. We are significantly under the vehicle weight and actually carry less now than we did when we first bought the van. Busam Nissan has refused to treat this as a problem stating that this is the way the van is supposed to sit. We have over 20 vans in our fleet and were using this as a test. Thank goodness we only bought one. Stay away from this vehicle.
