I've had plenty of GMC in the bay over the years, and the transmission and driveline complaints on these don't surprise me. 3,543 on the NHTSA record across 102 model-year entries (2005–2026) is not a fluke. The complaints are spread across the lineup — no single model is doing all the work. That tells you it's an engineering or supplier pattern, not a one-off bad year. 19 fire reports on the federal record — not common in this category but documented and worth weight. Repair exposure averages $2,500, which is meaningful money outside warranty. Across the 1,545 complaints reporting odometer mileage, the median failure lands at about 60,654 miles. Pull a transmission fluid sample if you can. Color and smell tell you more than mileage alone. If the fluid is dark or smells burnt, walk.
