I seem to be getting a slight knocking sound at idle. It gets a little worse if I'm stoped and in gear. Anyone else have this?

For some reason I noticed this the other day. Its close to sounding like a diesel when standing outside listening.... but not quite as loud. I didn't notice it in the cabin.

Hi Tstraley,

I'm sorry to hear that you are having this concern and slight knocking sound. Have you visited your Jeep dealer to have this concern addressed? Please feel free to message us with your VIN and mileage for additional assistance.

So I checked with dealer and they were not concerned. They said the 3.6l is just a noisy engine and were only woried if noise was coming from top of engine as in valve noise.

Nearly 28K miles and mine still sounds like a diesel when idling. I have switched to using 91 octane and it does help...not a lot at idle but more when accelerating from a stop. It always sounds like the valves need to be tighter but each time I have it serviced they say its normal. After hearing other JLs I have to say its sounds the same as them....good or bad...don't know for sure but sort of just considering it a JEEP thing now.
