Bulletin No.: 13384
Date: November 2013
CUSTOMER SATISFACTION PROGRAM
SUBJECT: Low Rear Differential Fluid Level
MODELS: 2014 Chevrolet Corvette
THIS PROGRAM IS IN EFFECT UNTIL NOVEMBER 30, 2015.
CONDITION
The rear differential assembly in certain 2014 model year Chevrolet Corvette vehicles may
have been shipped from the supplier with insufficient fluid. Operating the vehicle without
sufficient fluid in the rear differential assembly could produce a loud whine and/or gear or
bearing noise.
CORRECTION
Dealers are to inspect the rear differential fluid level and add fluid, if necessary. If fluid is
required, dealers are to also road-test the vehicle and listen for rear axle noise. If a whine, gear
or bearing noise is present, dealers are to replace the rear differential assembly.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel
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.
For dealers with involved vehicles, a listing with involved vehicles containing the complete
vehicle identification number, customer name, and address information has been prepared and
will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or
sent directly to export dealers. Dealers will not have a report available if they have no involved
vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle
Registration Records.
