1. Symptom/Vehicle Issue: Headliner Rattle Around Perimeter Of Sunroof

Check the dual lock fasteners - if a fastener is not engaged between the headliner and the sunroof module a buzz, squeak, or rattle may be present around the sunroof opening of the headliner.

If any location is not secured press up until the pieces of dual lock are locked together. (Gently pull down on headliner near sunroof opening to check for engagement of dual lock fasteners.)

There are 5 dual lock fasteners on the standard sunroof and 14 fasteners on the dual pane sunroof.

2. Symptom/Vehicle Issue: Sunroof Inoperative

Discussion:

Some recent reports indicate the sunroof does not open. Inspection has revealed the main headliner harness to sunroof module may not be connected. The main sunroof harness connector originally taped to the headliner needs to be inspected for proper routing and connection. Inspect and connect as needed to resolve.



---------------------------------------------------
3. Symptom/Vehicle Issue: Sunroof Wind Deflector Noise

Diagnosis:

Some early reports indicate the top bow of the wind deflector vibrates at highway speeds. This vibration is mostly been described as a visual concern, however, some owners may complain of a slight noise associated with this movement.

Repair Procedure:

Review the concern with the owner as described. Drive the vehicle to duplicate the complaint, if the condition is evident, isolate the deflector, and note any change. If concern changed during the isolation, replace the wind deflector as needed. The new deflector and spring should resolve some wind related turbulence at highway speeds, it however will not correct concerns with rattles unless the attachment screws are loose.

Note: The wind deflector should not be replaced for rattle concerns when the sunroof is in the closed position.

Verification: Test the operation to complete.

4. Symptom/Vehicle Issue: Sunroof Creaks Driving On Uneven Surfaces, Bumpy Road Conditions

Discussion:

Some early reports indicate full vehicle sunroofs, sales code GWJ, Power Front, Fixed Rear may creak at times when driving through certain road conditions. Validate the sunroof is adjusted per the specifications as required. Apply Mopar Krytox Lubricant 4773427 to the sunroof seals, test the vehicle for noise to complete.

Thanks for the info, it appears to have solved the problem with my rattling sunroof. I found one of the passenger side headliner fastners was not engaged. I pushed-up and heard it snap and no more rattle. This is the simplest fix possible!

I had the same issue. Rattle was just noticeable. I found two clips on the right dude not snapped in. A little push on each solved the problem. You could hear them snap into place when pushing up on the headliner.

To anyone who works at the factory..1) thanks for all of your help on the forum and for what you do daily. 2) Is there any system in place where Jeep listens to problems that owners have and work to fix them so no new Jeeps leave the factory with the same problems?

My 2011 has developed a rattle in the sunroof. I believe it is the rear pane. I'll be addressing this when it next goes in for service.

Thanks for the post!

I have a 2014 Summit and some times I get a rattle noise right above my head by the sun visor. I hope I can find a loose clip and pop it into place. I hate like hell to buy a 55k Jeep and have a darn rattle a 300 miles. Sure don't want them to tear the darn headliner out, it never goes back in the same and then there's always the possiblity of getting more rattles or even worse damage to the vehicle it self. I printed off the diagram and I'm going to take it to the dealer have it documented and hopefully I can have a simple, quick fix.

I had a pretty good creak in my 2014 Summit, especially when the body was flexing (driveways, sharp turns etc). When I took it to the dealer to have a few additional items taken care of , I added this to the list. After a few days, they decided to replace the entire tract system for the sunroof, as they were unable to get the creak to go away. I should pick it up again tomorrow and we will see what change that makes.

Hello all. It seems I'm not the only one having a newly discovered water leak on the driver side sunvisor bracket. :-( I looked at the other threads here but I cannot figure out where the drain holes are. It's 2011 JGC Overland with the normal sized sunroof. Very frustrated. I appreciate the help locating the drain holes.

Is the rattle more pronounced the the interior shade open or closed?
The same for me. They had to replace the entire track system as recommende in the bulletin; which I dreaded. The interior shade could not be replaced ss taut/tight as from factory which pissed me off. But what choice did I have. I now just keep the interior shade open.

SUNROOF MOTOR AND MODULE INITIALIZATION

SINGLE PANE SUNROOF

INITIALIZATION

A new motor is shipped uncalibrated with no vehicle cycles having been run. After installation and connection of the wire harness, the following steps must be taken to initialize the new motor and module unit.

NOTE: Verify that the battery is in good condition prior to performing this procedure. Do not leave the vehicle on a battery charger while performing this procedure. If the voltage at the sunroof motor and module unit drops below 11 volts or exceeds 15 volts at anytime while this procedure is being performed, the motor and module initialization procedure will not be properly completed.
NOTE: If at any point during the following procedure the sunroof does not respond as expected, restart the procedure at Step 1.
Depress and hold the CLOSE push button of the sunroof switch until the sunroof sliding glass panel moves to the fully closed hard stop and then back to the tilt (VENT) position.
Release the CLOSE push button of the sunroof switch, then depress and hold the CLOSE push button again within 5 seconds.
As the CLOSE push button of the sunroof switch is held, the sunroof sliding glass panel will move to the fully closed position, then to the fully opened position and then fully closed again.
Initialization is complete. Release the sunroof switch push button.
REINITIALIZATION

The following procedure causes a previously calibrated and properly operating electronic motor module to relearn and update motor stall position and obstacle detection.

NOTE: If at any point during the following procedure the sunroof does not respond as expected, restart the procedure at Step 1.
Depress and hold the CLOSE push button of the sunroof switch until the sliding glass panel is fully closed.
Continue to hold the CLOSE push button of the sunroof switch. It will take at least 10 seconds for the initialization process to begin.
The sunroof sliding glass panel will move to the hard stop and then back to the tilt (VENT) position.
Release the CLOSE push button of the sunroof switch, then depress and hold the CLOSE push button again within 5 seconds.
