THE AUTOMATIC SLIDING DOORS WON'T CLOSE. IT OPENS UP AGAIN WHEN THE CLOSING SLIDE DOOR TOUCHES THE FRAME. THIS HAPPENS EVERY A FEW DAYS!! VERY FRUSTRATING. AND I SAW THERE ARE 4 OR 5 SIMILAR COMPLIANT REPORTS ON THIS ALREADY. SO LOOKS LIKE IT DOES HAPPENS ON A NUMBER OF VEHICLES ALREADY, NOT AN ISOLATED INCIDENT. *TR

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 SIDE TO THE DRIVER'S SIDE. IT FINALLY UNLOCKED ON ITS OWN AFTER NOT QUITE 10 MIN. MY CHILDREN WOULD BE DEAD IF IT HADN'T ALREADY BEEN COOLED ON THE INSIDE, BUT THEY WOULDN'T HAVE LASTED MUCH LONGER. THE DEALERSHIP STATES THAT THEY CAN'T DUPLICATE THE PROBLEM AND DON'T KNOW WHAT TO DO TO CORRECT. 3. NOISE IN STEERING COLUMN. RACK AND PINION REPLACED, ANOTHER REPAIR DONE. THE REPAIRS LAST ABOUT 5 - 10K MILES. 4. TRANSMISSIONS SLIPS. THEY DID A RESET OF SOMETHING, BUT TRANSMISSIONS STILL SLIPS, BUT THE DEALERSHIP STATES THAT THE TRANSMISSION IS FINE. 5. FUEL GAUGE. IT HAS ALWAYS FLOATED, WAS TOLD THAT WAS HOW GM MAKES THEIR GAUGES UNTIL I TOOK IT THE LAST TIME TO THE DEALERSHIP AND NOW THEY STATE THAT IT IS A FUEL SENSOR, BUT IT IS OUT OF FACTORY WARRANTY AND THEY NEVER EVEN LOOKED AT IT BEFORE AS THEY ALWAYS TOLD ME THAT IT WAS FUNCTIONING AS DESIGNED. *TR

THE POWER SLIDING DOORS ON THE BUICK TERAZZA VAN CONTINUALLY REOPEN WHEN THEY ARE CLOSED. THIS IS A SECURITY ISSUE AS ON MORE THAN ONE OCCASION THE DOOR HAS OPENED AS WE WALKED AWAY FROM THE VAN ON A PARKING LOT. THE SERVICE DEPARTMENT CLAIMED THEY CLEANED THE CONTACTS AND THERE WAS NOTHING WRONG WITH THE OPERATION OF THE DOORS. THIS PROBLEM OF THE DOORS REOPENING STILL EXISTS. *JB
