TSB: REVISON NOTICE March 02, 2017 Rev2: ? The applicability has been updated to include 2016-2017 model year Yaris vehicles. ? The entire bulletin has been updated. Some 2014 - 2017 model year Yaris vehicles may exhibit a condition where there is an excessive gap between the rear bumper and the body. This is due to a partial separation between the retainer and the bumper cover. Re-securing the rear bumper cover may not sufficiently prevent this gap from returning. The rear bumper retainers have been revised to provide additional retention force to the rear bumper cover. It is also recommended to replace the rear bumper cover during this process. Follow the Repair Procedure in this bulletin to address this condition.
