Summary
The Office of Defects Investigation (ODI) opened this investigation on April 19, 2020. ODI was made aware of seven consumer complaints related to model year (MY) 2012-2015 Isuzu N-series gasoline-powered trucks for unintended movement. ODI worked with Isuzu and peer manufacturers to understand the severity, failure mechanism and frequency of the issue. Attached is a report outlining these details, in addition to the investigation's chronology. This investigation is being closed with Isuzu releasing a technical service bulletin (TSB), with owner notification, to resolve the unintended movement issue in MY 2012-2017 vehicles. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor the issue and reserves the right to take further action if warranted by new circumstances.Please review the attached closing report for full details.
