China Vehicle Dependability Study (VDS)

Share This Page:
Long-term quality performance

The study, which focuses on problems experienced in the last 6 months of 13-48 months old vehicles, ranks vehicles in segments and examines eight categories: Exterior, Driving Experience, Features/ Controls/ Displays, Audio/ Entertainment/ Navigation, Seats, HVAC, Interior, and Engine/ Transmission. Overall dependability is based on the number of problems reported per 100 vehicles (PP100), with lower scores indicating a lower rate of problem incidence and higher long-term vehicle quality. Starting from 2017, J.D. Power’ will be transitioning the VDS study onto the new VDS5 survey platform. The new survey platform consists of more diagnostic questions and data to assist car manufactures in obtaining more accurate data that provides deeper insights and in turn, allow the conduct of better product quality improvement plans.
