China Vehicle Dependability Study (VDS)

Publish: November 2021

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. The study is an effective tool for manufacturers to learn about user’s feedback during their mid or long-term use of vehicles so as to enhance product quality management.

Starting from 2017, the VDS study has been transitioned onto the VDS5 survey platform. The new 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.

Evaluate problem symptoms in 8 vehicle system categories:

  • Body appearance
  • Configuration / Control / Dashboard
  • Seat
  • Body interior
  • Driving experience
  • Audio / Communication / Entertainment / Navigation
  • Air Conditioning System
  • Engine / shifting system
