U.S. Customer Service Index (CSI) Study

CSI Hero

Study Details

Data Available Monthly

The JD Power U.S. Customer Service Index (CSI) StudySM continues to be the auto industry benchmark for measuring customer satisfaction with maintenance and repair service at new-vehicle dealerships, based on survey responses from owners of 1 to 3-year old vehicles.

In its latest evolution, we’ve significantly enhanced CSI to provide richer and timelier brand and competitor insights. CSI now delivers automakers a monthly look at both what customers say about their dealership service experience, based on our trusted Voice of the Customer data, and what dealerships are doing for customers, thanks to newly acquired vehicle repair data, based on tens of millions of reported service center visits.

And for the first time ever, CSI enables manufacturers to access competitive benchmark data and insights on a monthly basis, empowering them to react to new-vehicle dealership service experience concerns faster and more frequently.

The Benefits

Study subscribers will be equipped to:

  • Analyze key drivers of increased service satisfaction and retention
  • Benchmark service performance against other automakers
  • Dive deeper in Fixed Right the First Time insights, including analysis by IQS problem category

  • Compare service retention during the first three years of ownership with competitors

  • Service Initiation
  • Vehicle Pick-Up
  • Service Facility
  • Service Quality
  • Service Advisor
