Comebacks hurt the image of the dealership service department and the image of theGM vehicle brand. GM understands that due to ever increasing vehicle complexity, thisis a challenge. The service department should focus on the following critical areasin order to reduce comebacks:

The communication between the customer, service advisor, service manager and technician.Accurate and complete information on the repair order (R.O.).Always using the Comeback Prevention Flow Chart.When a customer has a complicated, difficult or intermittent condition or concern,use the appropriate customer concern verification sheet (CCVS) on the first servicevisit. Always use the CCVS on second and third repair attempts for the same conditionor concern.

Select the appropriate CCVS from the following four categories:

Automatic Transmission Driveability.Brakes / Steering / Suspension / Tires / Wheels.Engine Driveability.Electrical / Accessory.Use the Comeback Log if the customer's vehicle has returned for the same condition.Service management must review the Comeback Log weekly to identify any trends andto develop and implement the necessary corrective action plans.Technician training should be as up to date as possible.Institute a quality control program that includes service management vehicle inspections,road tests and verification of the repair.Contact the GM Technical Assistance Center (TAC) when necessary.
