On May 15, 2023, our 2017 Ford Expedition rolled while in Park and unattended. It had been parked for approx. 2-1/2 hours before rolling down our inclined driveway. It collided with our granite mailbox post, snapping it off. Thankfully, no one was hurt, however, the vehicle suffered significant damage.
Driving through a mile-long tunnel on an interstate highway (speed limit 55 mph), the vehicle ceased to respond to the gas pedal and would not accelerate or maintain speed. Attempted to shift gears but that produced no change - it was as if the transmission was stuck in neutral, but pushing the gas pedal did not increase the rpm. As we exited the tunnel at approximately 30 mph, the driver attempted to pull over and stop the vehicle, and found that the power assist for the brakes was not working, making stopping difficult - the driver had to push the brakes very hard, multiple times, to stop the car. We did contact 911 dispatch when we thought we were going to likely impede traffic, as the tunnel only had two lanes traveling the same direction.
