Vibration at idle

[Rharv]

my jlu has 700 miles I am noticing a minor vibration and idle speed I do not see any fluctuations is rpm at idle auto start turned off. I was wondering if anyone has had experience this, or if it just the balancing of the engine that does this from factory.

I noticed the same on mine. I disable ESS when I drive now to reduce the stress on the mounts. Also the squeal isn’t nice to hear...

Idle vibration is not normal. Take it in and have them check it out. My bet is a failed lifter.

Check out the "rough idle" wording in TSB 18-041-18 Rev B — Flash: Powertrain and System Improvements (PCM Reprogram) . Does this describe your idling? Even if it is close, might be worth a try. My rough idling didn't seem too bad, but after the update, it is super smooth now.

Hi. Our Jeep had some vibration at idle, while stopped at a light that I thought was a bit more than it should be as far as a vibration goes. However, it smoothed out significantly after about 2400 miles. This leads me to believe the full engine break in isn't complete until a couple thousand miles. Hope this helps.
