There are 3 owner-reported body & structure complaints for the 2009 Pontiac G8in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Was leaving for a road trip and the rear passenger door would not latch when closed. We were an hour from home, so I had to use a bungee cord to hold the door closed for the drive back. My son had to sit in the middle seat. That door is rarely used. I have ordered the part and it should be here soon. The drivers door has become difficult to open and close but I am unable to locate the part as it is backordered from GM. I understand the the vehicle is 12 years old but I maintain it very well; it is in great shape and runs well. It's scary to think that these door latches can fail so easily. Other body parts for this vehicle are becoming increasingly difficult to locate.
DOOR LATCHES GOES OUT ON VEHICLES AND THE DOOR DON'T STAY SHUT. THE DOOR WILL FLAP OPEN WILL DRIVING, HAVE TO USE A SEAT BELT AROUND THE INSIDE HANDLE AND THEN CONNECT TO THE SEAT BUCKLE TO KEEP DOOR CLOSE. I HAVE 2 G8S THAT THESE HAVE FAILED ON. I THINK THIS IS A MAJOR SAFETY CONCERN THAT SOMEONE CAN FALL OUT OF THE VEHICLE .
REAR PASSENGER DOOR LATCH FAILED ALLOWING THE DOOR TO OPEN BY ITSELF WHEN STOPPING THE VEHICLE.
