The GM Customer Concern Verification Sheets have been designed to improve communications between the service customer and the technician. The more clearly the technician understands the concern and its symptoms, the more likely the concern will be fixed right the first time.

The GM-wide Customer Concern Verification Sheets are available in DealerWorld. The Customer Concern Verification Sheets may be printed and reproduced locally.

The GM Diagnostic Worksheet has been designed to improve communications between the service customer and the technician.
