Tailgate sometimes opens while driving. It sometimes takes many attempts to reclose it from the outside of car. It will not reclose using the electronic button on the door. The alert comes on on the dashboard and its extremely dangerous as luggage can fall out. This happened while highway driving last week, scary. Apparently after googling this, it is common issue. The tailgate is one big gate hinged at the top so stuff can fall out.

Air Conditioner always make musty / moldy odor. Many forums says that is a common problem all across Mercedes models and it causes allergic reaction resulting in sneezing all the time when a/c is on. Problem is especially bad for my kids who have environmental allergy like mold/mildew. This horrible odor coming from a/c is due to mold/mildew forming on condenser. Please order a recall ASAP.
