Hood release mechanism is difficult to operate.
Inadequate lubrication of release cable.
Inject Teflon or silicone-based lubricant (Tri-Flow, GM Lubricant P.N. #1052277, or equivalent) into both ends of the cable housing using spray tube. Removal of cable is not necessary. Operate the cable with the hood up to work the lubricant through the cable housing. Repeat five times to insure adequate cable lubrication.

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.
