Body, doors & structure

The liftgate of my vehicle began opening on it's own at no apparent interval, but now occurs frequently while waiting for a repair part to come in. This has happened while parked - including in public parking lots (where someone malicious could have entered the vehicle and the closed the liftgate after entering the vehicle - I would have been unaware of their presence) as well as while driving, which presents multiple safety issues including belongings falling out of the vehicle or causing an accident.

Power Liftgate was functioning erratically and now it won't open at all. Currently there is no way to manually open the liftgate or access the rear of the vehicle without climbing through the vehicle to get to the trunk area. Electrical switches on inside, exterior of vehicle nor the keyfob will open the liftgate. Previously the liftgate opened on its own at unintended times and now it has simply quit working. Safety issue was when it was opening while driving. It is not currently doing this since it won't work anymore. Complete Failure happened around 54K miles.

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.
