SERVICE PROCEDURE
Mounting for the rear pillar molding on 2016 – 2021 Maxima vehicles now requires a
19/64th inch (7.5 mm) mounting hole for the rear clip and urethane adhesive installed in
two (2) locations. ALL rear pillar moldings on 2016 – 2021 Maxima vehicles must now be
installed using this method.
