Since the introduction of the BRZ, there have been a number of revisions to the rear combination
lamps and their sealing gaskets (a.k.a. packing) to address varying customer concerns. Conditions
ranging from the accumulation of water and condensation, to insect intrusion and lens / body
cracking have all been addressed in previous bulletins. Recently, concerns about a cloudy appearance
of the lens have created yet another bulletin. To help better organize these publications, all the related
bulletins are being been condensed into this new release putting all the information in one place for
easier reference.
As listed in their chronological order, design changes and procedures have been developed to address
customer concerns of:
? Condition 1: Condensation accumulation- inspection for possible cracking of lamp housing
? Condition 2: Condensation accumulation- flange (retaining) nut change for combination
lamp assy. to prevent rear body panel distortion and increased gasket (packing) thickness to
improve sealing.
? Condition 3: Trunk lid contacting (and in isolated cases cracking) the combination lamp
assy. when closing- change to the trunk stoppers and trunk weatherstrip
? Condition 4: Insect intrusion inside the combination lamps- further revision to the lamp assy.
and gasket
? Condition 5: Cloudy appearance of the lens- anti-fog coating applied at production to the
inside of combination lamp lens.
