## Summary

On December 2, 2022, the Office of Defects Investigation (ODI) opened PE22-013 to investigate allegations of loss of motive power accompanied by high coolant temperature messages on the dashboard of Model Year 2019-2020 Jeep Compass vehicles. At the time this investigation was opened, ODI was aware of fifteen Vehicle Owner Questionnaires (VOQs) for Model Year (MY) 2019-2020 Jeep Compass vehicles alleging a loss of motive power (LOMP) while driving.  The LOMP events were often accompanied by a high coolant temperature or coolant temperature too high message appearing on the dashboard of the vehicle.  In most incidents, the high coolant temperature or coolant temperature too high dashboard messages spontaneously self-corrected or were corrected after the vehicle was stopped and restarted. One complainant alleged no immediate restart, and the vehicle was towed.  A Preliminary Evaluation (PE) was opened to assess the frequency and potential safety consequences of these engine shut down events. On January 19th, 2023, ODI sent an information request letter to Fiat Chrysler US LLC (FCA) requesting pertinent information on the subject 2019-2020 Jeep Compass vehicles.  FCA provided its full response on March 2nd, 2023.  ODI has reviewed the information FCA provided as well as new reports submitted to NHTSA’s Vehicle Owner Questionnaire database.  Based on a review of available information, ODI has identified 173 subject vehicles that likely experienced a shutdown event associated with the high coolant temperature or coolant temperature too high dashboard messages.  ODI found the 2019 Model Year (MY) Jeep Compass as having the highest failure rate while also being the oldest group of vehicles in this investigation.  The 2019 Jeep Compass vehicles that experienced a failure represent an incident rate of about 0.09%.  The 2020 Jeep compass vehicles that experienced a failure represent an incident rate of about 0.04%.  After reviewing the information available at this time, ODI
