Component Dependability Reports – Portfolio Overview
Measure Long-Term Dependability at the Component Level
JD Power’s Component Dependability Reports provide suppliers with deep visibility into long-term component-level quality. Derived from the U.S. Vehicle Dependability Study (VDS), these reports reveal the specific problems and component replacements experienced by original owners of 3-year-old vehicles—helping suppliers understand how their parts perform in real-world ownership.
