The rear switch on our tailgate has failed and it allows the tailgate to open/close randomly on its own while the vehicle is locked even. I contacted Buick about the problem and they said didn-??t care, but this can happen while the vehicle is moving down the road as well as when parked. It-??s not necessarily a typical safety issue that are normally recalled for, but it does pose significant safety issues if you want your car to be locked and you come back from the store and it-??s not and people are free to break it or if it were to happen while moving. We had this happen on our car at around 38,000 miles. From reading other Buick forums to try and figure out what the cause is, it sounds like it-??s a somewhat common occurrence. It-??s alarming that it can open while the vehicle is locked.
