The Dodge Journey is a solid vehicle for the money. Keep the all the hinges and locks well lubricated. Some Chrysler products had an affinity for corroding door hinge pins and springs.
Also on the tailgate you should have several drain slots at the bottom. Make sure they are free and clear. One trick I have seen many hatchback owners do is to open the hatch and spray a thin film of lubricant up in the hatch to protect the inside corrosion. You dont need to get carried way, all your trying to do is keep the moisture out of the areas where the hatch skin seam with the inner metal structure.
