Weird sound when turning steering wheel at idle

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Colorado. The sound you're describing when turning the steering wheel at idle is often related to the power steering system. It could be due to low power steering fluid, a worn or loose serpentine belt, or even air trapped in the system. Check for leaks around the pump, reservoir, or steering gear if the fluid is low. A whining or groaning noise might suggest the pump is struggling to maintain pressure. One thing to keep in mind is that turning the wheel fully to one side puts maximum demand on the system and can redirect fluid through the high-pressure bypass valve, which can create a noise during normal operation. If you feel the noise is abnormal, inspecting the power steering components or having a mechanic diagnose the system is a good idea. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
