Condition
6051386
Some customers may comment that one, or both, of the roof panel joint front finish
moldings sit higher than desired where the forward area of the upper roof cap meets the
windshield.
Cause
The cause of the condition may be that the roof finish molding forward edge can contact
adhesives used in the build process, thus not allowing it to sit flush.
Correction
Upon verifying the condition, follow the repair steps in the Service Procedure below.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
