These may all be related but here goes... three problems
1. it keeps popping open when driving.. sometimes not for a few days.I have tried moving the striker plate, it doesnt pop out as much and open after doing this but still pops out.

2. It sits pretty low or is this normal



Sorry to much questions I know... any ideas??
3. When the door does open.. stationary, it doesnt catch and stay in place. its as if the catch on the door has vanished.
