“Vehicle: 2021 Jeep Grand Cherokee Overland, 3.6L V6 Incident Date: [XXX] Location: [XXX] Safety Complaint: On [XXX], while driving my 2021 Jeep Grand Cherokee Overland on [XXX], the vehicle suddenly lost accelerator response while traveling on the highway. The engine initially remained running, but pressing the accelerator pedal produced no response. Multiple warning indicators illuminated simultaneously, including the electronic throttle control, ABS, traction control, airbag, and four-wheel-drive systems. The vehicle also exhibited unusual electrical behavior, including unexpected activation of the high-beam headlights. The vehicle subsequently became completely inoperable and would no longer crank or start. The sudden loss of propulsion while traveling in highway traffic created a serious safety hazard and placed me at risk of a collision. This incident follows an extensive history of significant mechanical failures and repairs to this vehicle, including: Replacement of the cylinder head following repeated overheating and engine misfires. Complete transmission replacement following transmission-related failures. Replacement of the radiator and cooling fan…”
