When driving at very low speed there is a creaking sound which seems to be coming from the front side on the bottom. gmc has a service bulletin #pi1314:creak/poptype noise from right front of vehicle during low speed maneuvers-(sept.17,2014). the fix involves ripping up carpet and cutting a hole approx. 1 ft. square in front wall of interior. the seat has to be removed . the blower motor has to be removed. the right side front console trim plate and body hinge trim panel, then cutting a huge hole in the wall. i had a 2011 terrain, which i purchased new and i never experienced this problem. the noise is unacceptable for a brand new vehicle. *tr
