Summary

This 2016 report by the AAA Foundation for Traffic Safety, conducted by Atkins North America, investigates the feasibility of integrating telematics and connected vehicle data into the National Highway Traffic Safety Administration’s (NHTSA) defect investigation processes. The study was motivated by high-profile safety recalls involving manufacturers like General Motors and Takata, which exposed weaknesses in NHTSA’s ability to identify and analyze safety-related defects efficiently. The research aimed to determine if data from vehicle sensors and connected systems could supplement or replace existing data sources to improve defect detection. The methodology involved a detailed review of NHTSA’s current defect analysis processes, an examination of available telematics data from specific vehicle models (2015 Ford Fusion, Toyota Camry, and Chevrolet Malibu), and interviews with NHTSA staff, OEM representatives, and other stakeholders. The authors analyzed the limitations of NHTSA’s two primary data sources: public consumer complaints and manufacturer reports required under the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act. They also assessed the technical variability of diagnostic trouble codes (DTCs) and parameter IDs (PIDs) across different manufacturers to evaluate the potential for standardization. The findings indicate that using connected vehicle data to improve defect analysis is not feasible in the near term due to the existing technical environment. Significant barriers include the lack of standardization in data formats and code types across manufacturers, as well as NHTSA’s limited staffing, funding, and analytical toolsets. The report highlights that current OEM data is often obfuscated, non-standardized, and delivered in difficult-to-query formats, while public complaints suffer from inaccuracy and low volume. Although NHTSA is implementing improvements recommended by the Office of Inspector General, such as better data verification and statistical testing, the agency lacks the resources to effectively mine large datasets. The study notes that while connected vehicle technology is advancing rapidly, the immediate integration of such data into NHTSA’s workflow is impractical. The significance of this report lies in its identification of systemic gaps in federal vehicle safety oversight. It underscores the urgent need for NHTSA to enhance its data aggregation capabilities and adopt standardized data formats to enable more effective defect identification. The authors suggest that while direct integration of connected vehicle data is not currently viable, external stakeholders like AAA could support NHTSA by improving data gathering methods, such as developing apps for more detailed consumer reporting. The report concludes that although the technology holds promise for the future, immediate improvements must focus on refining existing processes, increasing staffing, and ensuring manufacturers provide more transparent and usable data.

Key finding

In the current technical environment, connected-vehicle and telematics data cannot efficiently support NHTSA defect analysis in the near term due to non-standardized diagnostic codes, manufacturer data-sharing resistance, and ODI staffing and analytic limitations, though standardized real-time feeds remain a promising long-term direction.
