Study Details
Data Available Monthly
Since 1987, the JD Power U.S. Initial Quality StudySM (IQS) has served as the auto industry standard for benchmarking new vehicle quality. The latest evolution is no exception.
Uniting newly acquired, state-of-the-art vehicle repair data with our traditional Voice of the Customer data, the enhanced IQS delivers automakers the ability to quickly identify potential issues early on before they become bigger problems in the quality landscape.
And for the first time ever, the enhanced IQS enables OEMs to access data updated on a monthly basis. This revolutionary change empowers automakers to make better and more informed decisions in guiding product improvements throughout, rather than only between, model years.
