“ Clack” or “Popping” Sound from Trunk
and /or Rear Shelf Area

12-140-12R

10/15/13

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*610808.
