SUBJECT:
"Clack" or "Popping" Sound from Trunk
and /or Rear Shelf Area
INTRODUCTION
The purpose of this bulletin is to provide a repair procedure to address a customer concern of a "clack" or "popping" sound from the trunk and / or rear package shelf area. The sound may occur over bumps or when a twisting motion is introduced into the vehicle chassis at low speeds. The tendency is for the sound to originate on the Driver's (l/hand) side (Case # 1). The procedure for Case #1 will remedy the majority of vehicles with this condition. After verifying the customer's concern and performing the procedure, be sure to road test the car again to confirm the sound has been repaired. In a rare instance where the sound persists, the Case #2 procedure will need to be performed.
COUNTERMEASURE IN PRODUCTION
A countermeasure was incorporated into production in July, 2012 starting with VIN number D*602788.

SERVICE PROCEDURE, CASE 1
The photo shows the location of the area of the spot weld to inspect on the Driver's (left) side.
Using the tip of a flat-blade screwdriver, CAREFULLY separate the plates of the spot weld area "A" ONLY approximately 1/8" (3.5mm) as shown in the photo below. For spot weld area "B", only grease will be applied at this time.
After spraying the grease into the gaps, use a suitable method to CAREFULLY reduce the gap between the lower and middle plates as shown in the photo on the next page. Take proper precaution to prevent damage to the paint.
Once the gap has been reduced, wipe off any excess grease then be sure to touch up any damage to the finish as necessary. Once the Case # 1 procedure has been completed, road test the car to confirm the sound no longer exists. If the sound persists, the following Case # 2 procedure will be required.
SERVICE PROCEDURE, CASE 2
Use the procedure in the applicable Service Manual for removing the rear package shelf trim cover and third brake light assembly to gain access to the inspection area shown.
IMPORTANT:
Due to the tight confines of the package shelf area, use extra caution to protect the rear window glass from damage.
Using the tip of a flat-blade screwdriver, CAREFULLY separate the plates of the area approximately 1/8� (3.5mm) as shown in the photo above (left). Do not spread the plates apart any further than necessary to allow the spray grease to be applied as shown in photo above (right).
The illustration shows a suggested method for closing the panel gap of the rear shelf. The socket end of a long ratchet or breaker bar is held solid with one hand while pulling the bar down firmly with the other after placing the opposite end on the shelf area separated to apply the grease. Be careful not to uses excessive force which may distort or damage the package shelf.
IMPORTANT:
After a road test to confirm the sound has been eliminated, be sure to wipe off any excess grease from both the top and underside of the package shelf.
Before re-installing the trim and third brake light assembly, be sure to touch-up any damage to the finish as necessary then re-install the package shelf and the interior trim to complete the repair.
