2006 BUICK TERRAZA Latcheslockslinkages Problems

IT IS PROBABLY A SHORTER LIST TO LIST WHAT WE HAVEN'T HAD TROUBLE WITH , BUT HERE GOES. 1. THE BACK POWER SLIDING DOORS WILL OPEN AND SHUT AT WILL. DRIVING DOWN THE ROAD, PARTED IN THE GROCERY STORE PARKING LOT, ETC. THE NEIGHBORHOOD KIDS REGULARLY COME OVER TO TELL ME MY DOORS ARE OPEN. MY HUSBAND ALMOST MISSED A FLIGHT BECAUSE HE SPENT TO MUCH TIME TRYING TO FIGHT WITH THE DOOR TO STAY SHUT. THEY HAVE REPLACED ALMOST EVERY PART OF THE DOORS SEVERAL TIMES, BUT WAS TOLD BY THE DEALERSHIP THAT LAST TIME I TOOK IT IN THEY DIDN'T KNOW WHAT TO DO NOW. 2. DOOR LOCKS WILL LOCK AND UNLOCK AT WILL. ONE DAY IT LOCKED MY 1 YEAR OLD AND 3 YEAR OLD IN THE VAN WHEN IT WAS 107. IT LOCKED THEM IN FROM THE TIME IT TOOK ME TO WALK FROM THE PASSENGER...

TL*THE CONTACT OWNS A 2006 BUICK TERRAZA. ON NUMEROUS OCCASIONS, THE DRIVER'S SIDE SLIDING DOOR WOULD OPEN AND REMAIN OPEN. WHEN THE DOOR WAS CLOSED, THE ALARM WOULD SOUND AND THEN THE DOOR WOULD REOPEN. THE DOOR FAILS TO SHUT PROPERLY. WHEN THE PASSENGER SIDE SLIDING DOOR WAS SHUT, THE ALARM SOUNDED AND THE DOOR WAS REOPENED. IT THEN FROZE AND WOULD NOT SHUT. THE VEHICLE HAS BEEN TAKEN TO A DEALER ON FOUR SEPARATE OCCASIONS, BUT THE FAILURE PERSISTS. THE CURRENT MILEAGE WAS 24,200 AND FAILURE MILEAGE WAS 5,000.
