SUBJECT:

Service Update for Inventory and Customer Vehicles
Buzz Noise at Lower Right Side of Windshield - Replace Air Inlet Grille
Panel
Expires with Base Warranty

MODELS:

2012-2013 Chevrolet Corvette

This service update includes vehicles in dealer inventory and customer vehicles that
return to the dealership for any reason. This bulletin will expire at the end of the involved
vehicle's New Vehicle Limited Warranty period.
PURPOSE
This bulletin provides a service procedure to replace the air inlet grille panel on certain 20122013 model year Chevrolet Corvette vehicles. The soft edge of the air inlet grille panel may
separate from the base at the lower right side of the windshield. If this occurs, the soft edge of
the panel may contact the windshield while driving at highway speeds, creating a buzz noise.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System Investigate Vehicle History Application. Dealership technicians should always check this site to
confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is
important to routinely use this tool to verify eligibility because not all similar vehicles may be
involved regardless of description or option content.
Additionally, a list of involved vehicles currently in dealer inventory is available on the "Service
Update Bulletin Information" link under the "Service" tab in GM GlobalConnect (US) or attached
to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that
return for service, for any reason, and are still covered under the vehicle's base warranty should
also be checked for vehicle eligibility.
