Does anyone else's engine sound like this?



2015 Grand Cherokee Altitude 14,400 miles

Knocking went away after about 2 mins and has not done it again since Saturday.

My SRT sounded like that after letting it sit for a few months. Like you it went away after a couple minutes or so. I was told by people here on the forum it's just lifter noise.

Thanks for the response. This only sat for 3 hours and was definitely a lower knock not like a lifter noise.

Have you had any issues with the motor since that happened?

No. None. I just try to make a habit of starting it ever couple weeks while its in hibernating. I usually run it for 20-30 minutes till she's good and hot.

Re: Does anyone else's engine sound like this?

Knocking after sitting such a short time is kind of alarming though. Maybe you should take it in and at least log a complaint with your dealer.

I brought it in today but they couldn't look at it. I have an appointment for Monday. I showed them the video, we shall see what happens. I searched online and couldn't find anyone else with a knock, saw lifter issues but no low end knocking. Just trying to see if anyone on here has had the issue. It may have done it more this winter but I wouldn't know because I use the remote start a lot in the winter to warm it up.

Oil levels are fine, oil pressure is fine and I had the oil changed 2,000 miles ago.

Re: Does anyone else's engine sound like this?

Something must have been starved for oil. Not a good thing. Maybe a burr on an oil passage or something restricting oil flow. Hope it turn out to be a fluke.
