2020 FORD EXPEDITION Fuelpropulsion System Problems

The SUV was driving smoothly at 55mph speed, suddenly I hit the break and tried to reaccelerate and felt a hard transmission shift, felt like metal hitting metal, felt like it was forced to shift to drive mode from parking mode. After that I started using 93 octane rated gasoline, do not observe the problem too much. I will really scary and unsafe, the whole SUV shook hard for 2sec.

We own a Ford Expedition 2020. In 2023, we started noticing jerky, harsh, and aggressive “slips” when the vehicle was trying to change gears - upon multiple occasions. But, in 2024, we experienced three, major, different instances - all were extremely scary and it was miraculous they didn’t cause accidents, car pile ups, or worse! The first instance, the vehicle jerked and sputtered just as I was pulling out into a busy intersection. I thought it was going to die in the middle of the road. The second instance, several weeks later, it happened, again, as our family was driving in pouring rain down the interstate; it jerked so hard it felt like we hit a small wall.

I spoke with a service rep at the local ford dealership who was able to look into the vehicle computer remotely but there was no record of the "Alert" or otherwise. I took the vehicle to my local mechanic who drove it and...

What component or system failed or malfunctioned, and is it available for inspection upon request? The Powertrain Control Module (PCM), which manages engine-transmission communication and regulates cooling system performance, malfunctioned, resulting in a cascade of related failures: Transmission system: Delayed shifting, hesitation, and eventually a “transmission stuck in park” code. Cooling system: Repeated overheating that led to a ruptured radiator. These issues stem from the faulty PCM referenced in Ford Recall 24E13, issued on April 25, 2025. Yes, the failed components remain in the possession of Harbin Motor Company in Scottsboro, AL, where the vehicle is still located. The vehicle has not been repaired and is available for inspection upon request. How was your safety or the safety of others put at risk? This vehicle was operated while exhibiting documented powertrain and overheating symptoms—including while transporting children. Harbin Ford repeatedly instructed continued use despite: Diagnostic scans on April 10, 2025...
