Engine Noise 3.6L

Whenever I'm stopped in traffic & idling there's a high pitch humming or buzzing sound which is pretty faint. The noise increases as I press the gas and then goes away. Is this normal for the V-6?
I've only owned my Jeep a few months but Coming from a Hemi this isn't a sound I recognize.
I searched for any prior posts on this issue & didn't find anything.

The electric steering assist (or whatever it's called). Mine makes a high pitch sound.

Re: Engine Noise 3.6L

I can hear a 'whine' noise when walking around the front of my GC while it's idling. I've always just assumed it's the electric motor for the power steering.

Inside?
The radio is usually on so I don't hear it.

I don't usually hear it inside with the radio on. But this week for the holidays I had some family riding with me so the radio wasn't on.

Have them stand near the rear when you start the Jeep!
Much better sound, even with the V6.
Nice growl.

Best sounding V6 I've ever heard even with the OEM exhaust.

For a real treat search YouTube for the new Ford Voodoo 5.2 liter V8 with the flat plane crank. Now that is a sweet sound.

I noticed a little growl last week when I remote started.... Thought I was just hearing things. Checked it it again today with the remote start. Not bad.

Re: Engine Noise 3.6L

I heard the same thing last week when my girlfriend drove and i stepped out of the car. But I heard it when she was turning the wheel. I assume that it was the power steering. The car is only 4 month old. Hope there's not a leak in the power steering somewhere.

Re: Engine Noise 3.6L

I hear the same faint noise you're describing. Glad to hear that it appears to be a non issue other than noise.

Re: Engine Noise 3.6L

It's the electric motor for the power steering pump. I've owned a few vehicles with this style pneumatic power steering to take strain off the engine. It's normal. If you start hearing a chirping sound, the water pump bearing may be going.
