Consumer Description

My 2018 Jeep Grand Cherokee suffered a sudden, catastrophic engine failure with no warning lights or alerts. Dealer confirmed the engine seized from overheating and cannot be repaired—replacement engines are on national backorder. This is my only vehicle, I’m 7 months pregnant, and I’ve been without transportation for 30+ days. This appears to be a widespread 3.6L Pentastar defect and a serious safety concern.
