Your silver car looks to be a wide body CMC? The hinge point is bolted to the ~2x2" steel bar that goes side to side. Perhaps the 2 bolts per side have vibrated loose? Look/feel up under dash to see if they came loose. Use lock washers or Nylock nuts so they don't vibrate loose. Or as LeonC pointed out the pivot point could be wallowed out - use a larger pivot bolt.
