What NHTSA investigated

This investigation documented hte functional aberations that have occurred in the performance of the subject cruise control system.most of the malfunctions involved failure of the system to properly regulate vehicle speed when engaged, failure of the system to engage, or self-disengagement of the system. These problems were investigated and steps taken by the manufacturer to remedy their occurrences.service procedures were issued for vehicles in use, and a design modification made for new vehicles.no confirmed allegations of failure of the system to disengage upon command were identified.improved quality control procedures and design modificationsin the system were undertaken to ensure a more consistent level of system performance.the details of these findings and the resulting conclusions are contained inthe subject engineering analysis closing report.a safety-related defect trend was not identified at ehis time and further use of agency resources does not constitute a finding by NHTSA that a safety-related defect does not exist.the agency will take further action if warranted by the circumstances.
