Paint Chipping Due To Trunk Lid Movement – 2015 Subaru WRX & STI

NUMBER: 12-172-14R
DATE: 07/11/14
REVISED: 07/15/14

APPLICABILITY: 2015MY WRX and STI Models
SUBJECT: Paint Chipping Due To Trunk Lid Movement

 

INTRODUCTION

This bulletin provides a procedure for how to address a customer concern of side-to-side trunk panel movement and possible contact with the corresponding top edges of the quarter panels.  In some cases, this contact may result in chipping of the vehicle finish.

 

COUNTERMEASURE IN PRODUCTION

  • The new trunk weatherstrip was incorporated into production starting with VIN F*811343.
  • The longer (BRZ) trunk stoppers were incorporated into production starting with VIN F*811136.
  • A new design WRX / STI trunk stopper (p.n. 57533FE050) is scheduled to be incorporated into production during mid-July, 2014 starting with VIN F*812458.

 

PART INFORMATION

For STI models, in addition to the longer trunk stoppers, the trunk weatherstrip’s tubular sealing portion now has internal reinforcement in the area between the red arrows shown in the photo below.  This reinforcement serves to stabilize the trunk panel and eliminate the chipping.

SERVICE PROCEDURE / INFORMATION

There are 2 procedures to follow depending on the model of vehicle being serviced.  To summarize:

  • WRX Models – Replacement of the trunk stoppers only followed by a check of the trunk panel adjustment.
  • STI Models – Replacement of the trunk weatherstrip and trunk stoppers followed by a check of the trunk panel adjustment.

IMPORTANT NOTES:

  • BE CAREFUL to not tear the rubber material of the trunk weatherstrip when removing or re-positioning the replacement part.
  • When removing the original weatherstrip, be careful to not get any of the adhesive as shown below on the trunk liner trim panels.

Adhesive

 

  • There should be no extra effort or force (“slamming”) required to properly close the trunk lid after the replacement parts are installed.

STEP 1(Both WRX and STI Models) Replace both the rubber trunk stoppers with the longer version (currently used on BRZ, p. n. 57533FE040).  The photos show the current stopper on the left and the replacement longer version installed in position on the right.  Use a plastic trim tool between the stopper and the trunk panel to release the 2 “tangs” holding the original stoppers in place.

STEP 2:   (STI Models ONLY)  Replace the trunk weatherstrip and trunk stoppers.

REMINDER: always be careful to not get any of the residual weatherstrip adhesive on any of the trunk liner trim panels.

As shown in the photos below, align the square notch with the trunk latch striker. The arrow molded into the short, smooth portion of the trunk weatherstrip faces down toward the bumper cover.  On the top section (closest to the back glass), the blue dot should align with the center of the third brake light.

STEP 3:   After the trunk stoppers (and weatherstrip on STI models ONLY) have been installed, close the trunk lid while paying close attention to the points listed below.

REMINDER:  There should be no extra effort or force (“slamming”) required to properly close the trunk lid.

  • After the trunk lid is closed, look closely for any excessive, insufficient or uneven gap(s) around the complete perimeter of the trunk lid.
  • Make sure the trunk height is correct and that it fits “flush” with the corresponding edges of the rear quarter panels.
  • In most cases, there should be only minor adjustment needed to the trunk lid, if any at all. Pay close attention to the adjustment for “B” as shown in the table below.  If after close inspection, it is determined adjustment of the trunk lid is necessary for proper fit, use the Service Manual specifications supplied below EXCEPT FOR “B” which has been recently revised (shown in RED).  The Service Manual will be updated with the revised specifications in the near future.
