The 2006 Initial Quality Study is based on responses from 63,607 purchasers and lessees of new 2006 model-year cars and trucks surveyed after 90 days of ownership. The redesigned IQS is based on a new 217-question battery-up from 135 in previous years-to provide manufacturers with more information to improve problem determination and drive product improvement. The study also groups models in a revised J.D. Power and Associates vehicle segmentation list.

The 2006 study has been redesigned for the first time since 1998. Improvements to the study include: an enhanced questionnaire for owners to aid in identification of both defect and design problems; expanded coverage of new technologies; and additional details about the problems reported to help OEMs better identify how to address them.
