Some GMC Terrain owners report experiencing issues such as noisy engines, particularly while idling, which can be a source of concern. Additionally, some owners have noted a rotten eggs smell, potentially linked to catalytic converter or fuel system problems. There are also reports of loss of power uphill, which may indicate engine problems that can lead to stalling or diminished performance. Furthermore, some owners have experienced the vehicle pulling forward when stopping, a symptom that could be associated with transmission issues. It is crucial for owners to address these concerns promptly to maintain the safety and performance of their GMC Terrain, and seeking inspection from a qualified mechanic is advisable if these issues arise.
