NHTSA Complaint #11532173 — 2017 FORD EXPEDITION

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. However, no intervention was required as we reached the end of the tunnel and were able to pull over before the call was completed. The vehicle was towed to a dealership and they diagnosed a fuel pump and/or fuel pump module problem, but have ceased to respond to our calls for the past 48 hours, so we have no further information. The check engine light turned on when the car was restarted, but then later turned off, without any repair work having been completed.
