Official summary
Some 2015-2018 Mustang GT350 vehicles built on or before 26-Feb-2018 may exhibit an excessive panel gap where the rear bumper cover meets the rear quarter panels on either side of the vehicle. This may be due to the method used to fasten the rear bumper cover to the vehicle. Follow the Service Procedure steps to correct the condition.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
