GMC Terrain won't start, just clicks and lights remain on on GMC Terrain

Some GMC Terrain owners report experiencing starting issues characterized by clicking noises while the lights remain on. These problems are often attributed to a dead or failing battery, which can lose its ability to hold a charge over time, particularly in extreme temperatures. Additionally, some owners encounter difficulties due to a faulty starter that prevents the engine from cranking, resulting in the clicking sound. There are also reports of electrical faults that could range from a dead battery to a malfunctioning starter or other components. Furthermore, issues with the fuel system, such as clogged fuel filters, faulty fuel pumps, or an empty fuel tank, can contribute to the inability to start the vehicle. For those facing these challenges, it is advisable to check the battery for corrosion, test its voltage, inspect the starter, and ensure the fuel system is operational. If these steps do not resolve the issue, seeking assistance from a mechanic may be necessary.
