I purchased a brand new 2026 Jeep Grand Cherokee L Summit in April 2026. At approximately 1,205 miles, while traveling with my wife and [XXX] child in [XXX] , the vehicle suddenly developed a flashing check engine light and severe engine misfire condition. The engine began shaking violently, idling rough, and lost smooth drivability during operation. I scanned the vehicle using an OBD-II scanner and the PCM stored diagnostic trouble code P0302, indicating a cylinder #2 misfire.
