Here is my newest issue. Going up any incline at low speeds and valve train sounds terrible. Have got gas at several different places and still nothing. Dealer said it should be ok. Drive it till it breaks then repeat lol.

I couldn’t hear anything, do you have a higher resolution version of this video? Did you record it with some sort of webcam?

Sorry no. Had to record it with the phone. Basically it sounds like low octane knock.

Isn’t there a service bulletin out right now for knock?
Dealer actually said that in the owners manual it says knocking is normal on th 6 cylinder. I'm digging right now.

Yeah I just pulled up that service bulletin for you and it says for the 2.0L motor only.. I would imagine they will come out with one for the 3.6L as clearly people are experiencing this issue. I’m pretty sure the [email protected] owners manual does NOT say our 3.6L’s should knock LOL

I’ve got it too. Goes away slightly with higher octane and almost completely gone in cold temps.

Doesn’t bother me too much. Got the lifetime warranty so if there issues down the road then it’s covered. I’m more worried about the other issues popping up about the Wrangler on this forum; wobble, frame welds, trackbar weld, etc.

I to have a load of issues to worry about. I just had the windows down the other day and heard it. Its really bad in person and my dealer is useless.

I haven't had any misfire codes yet. If I run premium fuel it seems to not be as noticeable.
