My 14' SE i4 locks when the trunk is left open for about a minute. To make things a little more confusing is that the car does not auto lock if the trunk is closed, I know this because when I get to work I never lock my doors. The first time the car locked with the trunk open I thought I must have accidentally hit the lock button on the key, but I have tested this with the key left in the house. Anyone else have this happen to them? Thanks.
