The J.D. Power Initial Quality Study surveys new vehicle owners to find out what problems they had with their vehicles in the first 90 days of ownership. J.D. Power conducts the study annually to evaluate the new car models released each year.
The study groups vehicle issues into eight categories: driving experience, exterior, seats, engine/transmission, features/controls/display, interior, HVAC and audio/communication/entertainment/navigation. The company produces a separate study for each country in which it does research on vehicles. A high ranking in this study is usually very helpful for vehicle sales.
J.D. Power also conducts a similar survey for customers who have owned their vehicles for two years.
