Car locks working just fine until we cross the American border and all of a sudden we hear this click click click sound. My husband and I think it is our command start that is stuck and thus causing the power door locks to open and lock ...open and lock. Long story short none of the above we end having to remove the fuse because it is annoying having that continuous clicking sound. We attempted several times to manually lock the door only to have it automatically unlock itself...freaky I tell you. Even as I now type this our door locks continue to do this as we have attempted to put the fuse back only to remove it once again. Any one else have a similar story. This will be our last Chevy purchase as they DO NOT STAND BEHIND THEIR PRODUCT KNOWING FULL WELL THERE ARE SERIOUS ISSUES WITH THIS MODEL.
