Jun 26, 2019 · I have a 2014 Silverado LTZ (very high milage - 219,000) Runs great and still has some power left under the hood. For the most part, it is in great shape. It have a strange noise when acceleration or getting up to about 3 or 4 thousand RPM.
Listen to what your car is telling you by learning about the possible causes of common car noises. Cars produce an array of noises. From the sound of your tires gripping the pavement to the revving of your engine when you accelerate (unless you drive an electric car), most of these noises indicate a perfectly functioning vehicle.
