U.S. Initial Quality Study (IQS)
The Industry Benchmark for New-Vehicle Quality
The U.S. Initial Quality Study (IQS) is the automotive industry’s definitive measure of new-vehicle quality, tracking owner-reported problems within the first 90 days of ownership. Combining verified repair order data with customer feedback, IQS delivers the most comprehensive view of launch performance across brands, models, and segments.
What It Measures
A Complete View of Early-Life Quality
Evaluates problems per 100 vehicles (PP100) across 227 categories:
• Mechanical systems and design execution
• Features, infotainment, and emerging technologies
Includes:
• Integration of survey data and verified repair orders
• Brand and model-level diagnostics
• Monthly and annual performance tracking
