Thanks for taking the time to interact with us like this--it is really appreciated!
We appreciate your feedback. Our engineers are constantly reviewing warranty data and field return parts so we can improve our component designs.

Thanks again for your input.

I mean I think it is interesting that Jeep/Chrysler/Dodge will not fix this issue on the engines that make this noise and they actually say its normal. I have been in several Hemi's that do not make this noise and would just like my Hemi to sound the same but dealer said NO...
As with any mass-produced product there will be some normal variation. Also, depending on the vehicle acoustics, some may transmit the noise more than others. Rest assured it won't harm anything.

For legal reasons, all packages we offer have to pass rigorous limit handling tests. Lifting a vehicle jeopardizes the vehicle's ability to safely handle under emergency maneuvers. The Rubicon JK and TJ did not have any suspension lifts. They were slightly taller than the standard models solely due to the larger tires fitted to them and they were able to pass all handling tests.

How does the aurea portion of the Bluetec work, in terms of replenishing and frequency of this schedule. Additionally what is the lifespan of the catalytic convertors or particulate filters and how does the warranty handle the replacement?

The body shop manager told me that they would have to prove that the lift added caused the failure or accident to void any warranty. Just dont drive wrecklessly.

Great to hear it from an engineer!!!

Thanks for being here today.

I love my jeep,

Why does the WK's paint have so much orange peel compared to other makes like the 300C

The Diesel Grand Cherokee does not use Urea. The diesel particulate filter and catalytic convertors used have been extensively tested, and pass all the Jeep durability requirements.

Thanks for your interest!

He's right. We don't automatically "void" a warranty because of modifications, but if something fails as a result of the modifications, repairs for those failures would not be covered.

There is a Technical Service Bulletin regarding this specific issue: TSB 23-015-06. The bulletin describes the procedure used to clean the white residue from the seats.

If under warranty, a dealer can perform this work. Otherwise, use the following procedure (text pulled from the service bulletin):

1. Vacuum the cloth seat fabric.
2. Mix a solution of dish water detergent and WARM water. Do not use hot or cold water.
3. With a clean sponge, wet the vehicle cloth seat fabric. Dampen the cloth seat fabric.
Do not allow to cloth seat fabric to become soaking wet or too dry.
4. With a soft brush, agitate the soap solution and the loose residue material. The intent
is to mix and suspend the loose residue material into the soap solution.
5. With COOL water, rinse the cloth seat fabric to remove the soap and residue solution.
6. With a shop vacuum, vacuum the cloth seat fabric of any excess moisture.
7. Repeat the cool water rinse and vacuum.
8. Allow the cloth seat fabric to dry.

Thanks for your question!

I am a diehard Cubs fan (something you can't help me with) and a fanatical Jeep owner.

I hate to think that the JK is the only live axle Jeep as some of us prefer a wagon like a XJ/WJ and now WK. I know my current idea is a screw loose question, but why couldn't the UpCountry package on the WK be more meaningful like the Rubicon package is to the TJ/JK?

I wish the UC package included a solid front axle in place of the IFS. Not that it is that evil, but someone that buys the Up Country package would understand that the trade-off is a vehicle that is more off-road oriented than street. Then guys like me can buy a CRD WK in UC trim and have a vehicle that meets my preferences.

Any large reason why the uniframe can't be adapted for both scenarios?

Mod Edit: No one can help you with your misguided Cubs fandom. Go Sox! -dakuda

I was thinking of adding some undercoat spray to the wheel wells to deaden the sound a bit.
The trim piece was removed for aesthitics(sp) only. I am not sure if the spray would deaden the sound, but if it does, please return to the forum and let us know or

First of all, I would like to intorduce my self, I'm Diego, a owner of a Jeep/Dodge/Chrysler dealer for Peru. I don't have a 07' GC but since I sell them I have few details/compliments about my customers that I would like to share, also ask some technical questions.

1) Drivetrain & Electrical (Specially talking about 05'-06' and some 07' WH 4.7L V8)
  • Stall , die from the nowhere engine problems. Why happens this? Even with the propper upgrade software for FCM, PCM/TCM and rest of module from the DelaerConnect, wich I have acces as well. No TSB is present at this time at the DealerConnect for this big problem. We think sometimes has to be with something inside of the transmission or either with the SKREEM module.

Here are some links you may want to check for this issue.
  • Front Suspension. Why is so soft the fromt suspension? Can't be upgraded to something bit stiffer? Every customer that bought me a WK 4.7L V8 complimnets about it. On the highways with non flat surface at all, the Jeep will give you a "float" sensation and it creates some fear in drivers.

  • Driveshaft. Not much issues over here, just couple of WK/H's had to replace from new in warranty due making noise and vibration at high speeds. Maybe Jeep engineers could check for strenght of this piece and make it more solid to prevent this issue.
  • MPG. Many customers had the previous GC WJ 4.7L V8, they say with their new WK/H's 4.7L , the MPG dropped quite a bit. I know this is a heavier plataform, but it's substancial the decrease in MPG it give us the new paltaforms vs the WJ. We have from 90, 95, 97 and 98 octane fuel over here, using any of these won't help to get more decent MPG. Most are about 10-11 MPG in cit and no tmore than 14 MPG in highway. I know this depends on traffic, driving habits/style and other couple of things but it's too low for in my opinion. Exist any upgrade?
  • Exhaust Resonator. I notied the 4.7L and 5.7L HEMi V8 engines are loud compared with the old WJ exhaust system. Sounds like a old V8 with leaky exhaust. Many customer noticed this and don't like it.

2) Comfort and Interior
  • A/C vent slots. They can't seal enought decent while the blower is activated. Previous model seal very good but WK's not. I'm not the first person pointing this, I have read in some foerums about the same. If someone want the cockpit fresh/cold but don't want the air hitting agaisnt your face or any othe part of your body, you close the a/c vent slots so the blown air slowly go can fresh the cabbin.
  • Try this... put slow blower fan speed with A/C, seat in the back seat and wait some minutes, you will freeze. Why? Because the rear vent slots can't seal enough. While the driver/copilot want A/C , the rear passengers could not want A/C. One customer told me every time he took some passengers in the back seat, he had to add a little toilet in the arms rest to block the blown air comming from the vent slot to prevent freeze of the passengers.

Seats. Why are the seats for thw WK/H's too rigid? They don't offer ennough lateral support like the previous WJ models, wither comfortable at all. Many new customer of the GC compliments about comfort for long trips. Pain in the back.

Some has troubles with the height , agaisnt the roof. The distance it's too short even with full lowered seats.

Why the copilot electrical seat doens't have anymore the option to to adjust in altitud? Just forward-backward and back reclinable ?

A reference Thread HERE

That's all for now. If I have other question I will get back here. Hope you can read all, not be a pain to asnwer all this.

Thank you in advance.

-Diego
Diego -- Thanks for your note of concern. However, for tonight's purpose, I would have to suggest that you contact your local dealer support network to help resolve these issues. Thank you.
