2017 Yukon making this loud sound around 75k miles, at the morning start up, or if it has not been driven for several hours. Local mechanic hasn’t figured it out. Have not tried dealership yet. Want to know what I’m getting into before I take it there. It sounds like it’s coming from under the car. -
Hey guys, I'm just looking for suggestions on what to start checking for this engine noise. Best described as a tap with a squeak happening at about 1/2 of idle speed RPM. I hear it loudest with a stethoscope at the rear top of the engine. Vehicle is completely stock. Never had any engine work done. Oil changes done faithfully and currently using Amsoil SS 0w-20. Yes , i drive a lot and I've had to do just about every repair these vehicles are known for, But never messed with the basic engine. Maybe cam, HP fuel pump?? Thank you.
