Some 2015-2020 Transit high roof bus/passenger wagon vehicles may experience a loose or unseated headliner at the C and/or C 1/2 pillar(s) causing visible gaps. This may be due to a lack of retention capability of the headliner locator tabs to the pillar block pins. To correct the condition, install repair coupons to the headliner and replace the headliner air conditioning (A/C) vent foam gaskets.
