Hello fellow GMC enthusiasts! I'm starting this thread to share and discuss our collective ownership experiences with various GMC models. Whether it's a Yukon, Sierra, Terrain, or Canyon, we've all got stories to tell about our adventures, triumphs, and sometimes, misadventures behind the wheel of our trusty GMC rigs. Let's swap tales, ask for advice, and learn from one another in this thread - from maintenance tips to road trip exploits, no topic is off-limits!
