Re: 2011 Jeep Grand Cherokee TSB's(technical service bulletins)

dubwarren, is the rumble entirely gone? although better, mine seems to persist in auto mode from time to time, sometimes still quite noticeable at WOT. i too had the update.

very slight rumble persists. Didnt notice until this morning. Have you tried sport mode? Im going to switch to sport mode on my next drive to see. It only seems to happen during hard driving for me or while going around a sharp curve. It seems like the update made a difference though. i can give better feedback after a few days i think.

EXACTLY! hard driving or exiting a curve for me too. as far as i can tell it will not happen in sport mode, i've been trying.
if it does, it is really really faint. the reprogram was an improvement, but not a complete fix. i'll live with it for a little while, but i hope there's a permanent, all-modes fix.

I noticed that this TSB has been updated to 21-004-10 REV. A. I think I might take my Jeep back to the dealer and have this double checked.

Re: 2011 Jeep Grand Cherokee TSB's(technical service bulletins)

Dealer would not update any TSB's unless I experienced the problem. They did make sure some other codes were up to date.

Re: 2011 Jeep Grand Cherokee TSB's(technical service bulletins)

This is a great resource for Jeep owners. We have a 2011 Laredo with the X-package and are experiencing electrical issues mostly centered around the screen for the radio/navigation system: ipod starts streaming very fast at random times, clock runs fast, interior light dims then brightens, driver side heated seat cuts off after 15 minutes (passenger side does not); rear window would not go up from driver side controls.

Dealer kept the Jeep two days said he could not duplicate the issues so there is nothing wrong? Anyone else experiencing problems like this? Can't they run a diagnostic test on electrical?

Any help is appreciated.

As far as ipod starts streaming fast - there is a known issue that possibly will be fixed in the upcoming software upgrade for 430[N] radio.

I think someone posted about heated seat too, just search the forum.

I also have Laredo X and don't experience the rest of the issues you are describing. About heated seats - for me it gets too hot in 2 minutes and I have to power it off. I don't own an iPod.

Wish there was something like this for the RAM 1500 trucks.
