Structure
11 reports
“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”

The vehicle was taken to the dealer where it was diagnosed that a steering wiring cable might be detached. The vehicle was repaired; however, the failure reoccurred twice while driving. The vehicle was towed to the dealer where unknown repairs were completed. The contact also stated that the electronic stability control and the traction control warning lights had illuminated while driving. Additionally, the contact stated that the rear driver's side door handle was fractured. The contact also stated that the rear passenger's side sliding door handle was fractured and she noticed that the sliding door wiring cable had detached, causing the door lock chime to engage while driving as the door would no longer close completely. The manufacturer was notified of the failure but did not provide any assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 149,000.”

Steering
6 reports2 crashes1 related recall
“ON MAY 2, 2013, ABOUT 10AM, I WAS ON MY WAY HOME. THE STEERING WHEEL SUDDENLY OUT OF CONTROL AND MY CAR HIT ON A CAR PARK ON THE STREET SIDE WITH NONE INSIDE. MY CAR HAD SEVERE DAMAGE AND COST ABOUT $10,000.00 TO FIX. THE OTHER CAR I HIT ON HAD MEDIUM DAMAGE. THE AIR BAG POP OUT WITH A LOT OF DUST AND IT WAS FLAT. A LOT DUST BLOW ON MY FACE. THE AIR BAG HAD NO AIR AT ALL. IT WAS ALL FLAT. THE STEERING WHEEL HAD BEEN KIND OF TIGHT AND DIFFICULT TO TURN FOR THREE YEARS. I THOUGHT IT WAS NORMAL FOR THE BIG VEHICLE , SO I HAD NOT BROUGHT ATTENTION TO THE DEALER. I REQUEST THE NHTSA TO INVESTIGATE 2006 BUICK TERRAZA'S STEERING SYSTEM. I AM SURE THAT SOMETHING IS NOT QUITE RIGHT IN THE STEERING DESIGN AND MANUFACTURER. *TR”
