Passenger seatbelt locks will not unlock unless you unbuckel the belt it just keeps getting tighter have a problem where the you push down on gas it won't do anything for a moment then jolt forward an the main problem it with the electric if you barley touch the ignition switch or controls for the seat the seat moves the ignition also not only moves the seat but a couple times it has shut the car off and once locked us in the car had to put the keys in and start to get it to unlock and once locked us out with keys still in ignition switch.
Driver's seat moved back, dome lights illuminated (vehicles "easy exit" feature) while driving at highway speeds. Luckily I am tall enough to reach the pedals and wheel while the seat was moved back, but my wife is only 5' 4" and would have a hard time reaching. This is a serious issue that has been happening to many other Mountaineers as evidenced by the many reports on the internet. The cause is any slight bumping of the ignition switch or the steering column/wheel.
