Had the same situation on our 2016 Miramar 34.2, got off at an exit and one of the side LOCKED compartment doors opened. Fortunately the people in the car behind us honked their horn and got our attention otherwise that would have been a disaster. Turned out that the lock mechanism needed adjustment. I checked all the others and found 3 that needed adjustment as well. Now before we leave, both myself and my wife double check all the compartment doors and give an extra push on the propane door.
