GMC Terrain faulty transfer casing replacement issue noted by dealership on GMC Terrain

Some GMC Terrain owners report experiencing ongoing transfer casing problems, which have been noted since the vehicle's first generation. Many owners choose to repair these issues themselves or seek help from trusted mechanics, leading to incomplete data reporting by dealerships. The average cost for a transfer case replacement at dealerships can reach approximately $2800, including parts and labor. Additionally, government regulations do not require a recall unless there are significant complaints or accidents related to the transfer casing issue, which underscores the challenges and costs associated with addressing these persistent problems effectively.
