The hinges and the latch assemblies on the doors,
Hood, and liftgate must be well sprayed with a couple of drops of light oil or lock lubricant once in every 3,000 miles or in every three months or so. The door latch strikers can also be functionalized with grease in order to reduce wear and enhance a smooth operation. Spray-on graphite lubricant should be applied on the door and liftgate locks.
