NHTSA Complaint #11234147 — 2018 CHRYSLER PACIFICA PLUG-IN HYBRID

METALLIC BUZZING / VIBRATION DURING MODERATE ACCELERATION. OCCURS OCCASIONALLY AROUND 30 TO 35 MPH BUT ALSO AT HIGHER SPEEDS. VEHICLE HAS BEEN AT DEALERSHIP MULTIPLE TIMES WHERE THE BELLY HEAT SHIELD WAS REPLACED, ROCKS WERE REMOVED FROM THE HEAT SHIELD, UNDERCARRIAGE WAS INSPECTED AND PARTS SECURED, AND MOST RECENTLY THE ENTIRE TRANSMISSION WAS REPLACED. ALL OF THE WORK HAS BEEN PERFORMED UNDER WARRANTY AS THE VEHICLE ONLY JUST PASSED 20,000 MILES. EVEN AFTER THE TRANSMISSION WAS REPLACED THE BUZZING SOUND CONTINUES AS BEFORE RESULTING IN ANOTHER TRIP TO THE DEALER. THERE HAVE BEEN NO ISSUES WITH THE OPERATION OF THE VEHICLE YET BUT I AM CONCERNED THAT THE BUZZING / VIBRATION IS INDICATIVE OF A FUTURE ISSUE THAT WOULD RENDER THE VEHICLE INOPERABLE.
