U.S. Customer Service Index (CSI) Study

Benchmarking the Experience That Keeps Customers Coming Back

The U.S. Customer Service Index (CSI) Study measures satisfaction with dealership service visits for vehicles one to three years old—across both warranty and customer-pay work. By combining customer feedback with real repair order data, CSI delivers one of the industry’s most complete views of aftersales performance.
