Time is allowed to inspect these areas during the predelivery process and correct any deficiencies that are discovered, hence a repair in any of these areas would constitute a comeback. If a vehicle were to return for repairs in these areas within this 1000 mile period, it should be assigned to the technician who performed the predelivery inspection.

Claims that are submitted for these labor operations within this period will be rejected for Reject Reason 39, Labor Overlap and will require authorization.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
