I have a 2013 GMC Terrain. I bought it used in 2014. It had one previous owner. When I bought this car, I didn't notice the abnormal noise it makes. While the car is either in driver or reverse, it makes a weird ticking noise coming from under the front hood. The noise goes away in park. However, the noise can only be heard when the car idols at a certain rpm. The car makes a rattle like sound when the rpms are low, like between 500 to 1500. For example: when I'm cruising down town at speeds of about 25-45mph, I can here the rattle sound. When I back into my garage, the noise can be heard even louder because the garage amplifies the sound. When I use cruise control to accelerate, it does not make this noise. Only when I put my foot on the gas pedal. When I take my food off the gas, or speed up, the sound goes away. It's not a low oil tick sound. It's a little different, like something is loose and rattling. This noise has always been there but it took me a while to realize it.
