2012 GC with 5.7 humming noise

Hi, new here.

Recently bought this Jeep and have noticed a humming sound when the ECO appears in the message center.

Stepping on the gas pedal slightly to increase speed, the sounds goes away and ECO also goes

I'm assuming it's the motor dropping off cylinders creating that sound

Advise to ease the concern appreciated

A friend has a 2012 Ram Hemi and he had a strange noise issue.
He took it to the dealer and it was determined the noise started when the hemi went from 8 cylinders to 4.
His is still running fine, but still has the noise but now he doesn't worry.

Yeah probably the MDS, if you don't like it, drive in 5 or 6 instead of drive. I usually do that except for when out on the open road.

Thanks ColdCase, I'll give that a try. I do quite a bit of 45-50 MPH around the city driving

I notice a noise in eco mode also but its more of gear noise. I figured its eco mode so has less power so its struggling a little?

Hello Racin8,

Sorry to hear about your experience with your Grand Cherokee. If you continue to have concerns, please donít hesitate to PM you VIN and contact info so I can set up a diagnostic check for you at local dealership.

Thanks for reaching out,
