2011 Grand Cherokee Hum
I have a 2011 Grand Cherokee Overland, 5.7 Hemi
Does anyone get a strange hum from the engine at freeway speed when the ECO light comes on? Is this normal? I find it annoying but liveable if thats the way it has to be.
I have heard the hum at lower speeds also. I know its running just 4 cylinders when the Eco light comes on but wished I didnt hear that hum. Is there a solution to that?
