2011 Jeep Grand Cherokee

    After my last service visit on this it seemed like the problem went away but the weather was warm for a few days and when it got cold again it came back. Once the warm weather set in the noise went away again and has not come back so I will have to wait until next winter to see if it comes back. It is a strange one as the dealer claims they have changed every component of the suspension in the back passenger side. Otherwise, my jeep has been great, put some new wheels on it and tinted the front side windows, looks great. I just had a software update done as per Jeep service bulletin 18-012-11 which has changed the shifting off the line and at slow speeds. It is almost as good as putting the jeep in sport mode, makes a big difference in around town driving.

    Gbees, can you tell me more about service bullletin 18-012-11? Does it apply to the Hemi V8 JGCs. What are the symptoms that the bulletin is supposed to remedy? Thanks!

    It looks like it is only for the V6 and covers several issues. Take a look at this

    For anyone having issues with V6 performance, you may want to take a look at this as I just had it done and you will see a difference.

    Thanks for the info! I also called my dealer who said the TSB doesn't apply to my VIN #.
  • Just took delivery of V8 JGC and hear a flutter sound at low speeds when car is cool. Sounds like playing card in bike spokes. Sounds like its coming from rear. Dealer cant hear it. Any tips?

    I also have a 2011 v8 JGC. It produces such a fluttering sound when I have one window open partially (esp back window) with all other windows closed. If I also lower another opposing window (front left and back rt) the sounds goes away.

    I have experienced this phenomenon with other vehicles.

    Hope this helps!
  • Thanks...this is called buffering and is actually addressed in the owners manual. The noise I am hearing sounds like its coming from the rear suspension or underside. Definitely mechanical, not wind or road noise.

    Thanks Again!

    I have the same issue. My dealer stated that this is a known problem and that jeep has published a service bulletin (17-003-10) about it. They followed the corrective action on the bulletin but the noise did not go away. They went on to say that the fix on the bulletin does not correct the problem.

    I filed a complaint with Chrysler customer service. That is being worked as we speak.

    I would file a complaint with them as well. The more noise about this problem the better.

    Buffeting.... I think.. :)

    Prices Paid, Lease Questions, SUVs

    I had wind buffeting on my last SUV, it was horrendious! Haven't driven with the windows down in my new JGC yet, way to hot here in Texas. Really like the ride, though, very happy with my purchase. Can't wait to take her to the Grand Caynon this year! First tank with the V6 got me 19.7. Not too far from the 20.0 I got in my 4Runner. In the Jeep, it's way too easy to find your self doing 10-15 mph over the speed limit.

    There is a suspension noise associated with 2011 JGC that is referenced in bulletin 17-003-10. I have a 2011 JGC w Hemi that has been to the dealer for this noise. They stated that this is a known problem. They performed the work but also stated that fix does not correct the noise problem.

    I suggest that you complain to Jeep's customer service dept. The more complaints the better. Maybe they'll do something.
  • You are correct! Sorry
  • The correct tire for the Overland with the Off-Road Adventure II Package is the Michelin LTX A/T 2 on-off road tire. I walked away from buying one today due to the Overland having the Michelin Latitude Touring tires on the vehicle.

    The window sticker stated the vehicle had P265/60R18 OWL On/Off-Road tires.

    I told the dealer when he gets the district to pay him to mount the correct tires I will buy the vehicle. This is becoming a major issue that Jeep had better resolve.

    Have you reviewed all the posts concerning the "wrong" tires on a jeep with the off-road package? There's a lot folks out there with the same concern.
  • Yes I have. Additionally I called JEEP-USA and a rep told me this was the first time they heard about the issue. I am waiting for the dealer to get back to me about getting the district rep to reimburse him to switch out the tires for the LTX A/T 2 tires. I can't wait to see what the dealer tells me since he wants to sell the car.

    It may be time for owners of the 2011 Overland with the ORA II package to consider starting a class action Lawsuit against Chrysler, if they bought the Overland with the Latitude Touring tires, and paid to have On/Off-Road tires put on. Another idea might be to contact your State Attorney office and file a consumer fraud report against Chrysler for the tire switch.

    Hopefully, if enough people did this it might lead to some type of litigation against Chrysler at various state levels. I doubt if the FTC would take any action since the Feds bailed out Chrysler.

    That's a good lie the rep told you. I called them in December, 3 says after my ordered Overland came in. I know many others that also made contacted Jeep for the same issue. I dealt with a good service manager and a good customer rep fm Jeep and I finally got.the issue resolved. It took almost 4 months but I got the LTX's fm Michelin. As far as I know no one else reported the same success. I dealt with some good, dedicated people.

    Has anyone installed an AVIS Bugflector II (bug deflector for the hood) on a 2011 JEEP Grand Cherokee?

    I have a new Jeep Grand Cherokee Overland with the 730N Radio/Nav system. I entered all my names and addresses and phone numbers into my "Address Book". Today I went to make a phone call and found my address book was empty!!! This was the second time this happened. The first time I just thought I must have made a mistake to clear it, but this is the second time it happened. I also lost my home address and phone number. Has this happened to anyone else?

    im currently trying to find an HID bulb kit or HID bulb for my 2011 JGC 4x4 laredo fog lights. However, the manuel only provides a part number, and the dealer can only provide the part number as well. I know the low beams are H11's per the dealer. Does anyone out there know what bulb type the fog bulb is? thank you
