The door locks unlock randomly. There is no pattern as to when it will unlock. I am concerned because the contents could be stolen or the vehicle could be carjacked when I'm not in it.

Back passenger door would not lock if it was unlocked. If it was locked it would not unlock with neither the remote or door switch.

Now the switch quit working. I feel like I bought a car built in a third world country that has no standards or quality control over what they make.
