I was backing up and the truck took off without my foot on the gas pedal. i have about 15k in damage to my vehicle. i have found a few others that have had the same problem
The vehicle has an issue down shifting from 5th gear to 4th gear. it causes the vehicle to actually shake and feels as if the vehicle was jarred. it is worse when you have the break applied to come to a stop. the dealership informed that this is an issue with the new 10 speed transmission and it's functioning normally. however it's very alarming when this happens and startles passengers in the vehicle.
Electronic dial shifter will automatically switch from drive to park if the vehicle start stop button is depressed when the car is running. the parking brake also automatically switches on at the same time. consider what would happen if a 2018 ford expedition is traveling on a freeway in traffic and the start stop button were accidentally depressed. the car would shift into park, the parking brake would engage and the driver would decelerate rapidly from 65 mph to a stop with no notice, likely being rear ended by traffic ie; a semi truck at highway speed. the electronic shifter should stay in the selected gear when the start stop button is depressed as a convention shifter would, electric or mechanical. i determined this after going to a car wash, putting the car in neutral then depressing the stop button to save fuel. the carimmediately shifted from neutral to park and engaged the parking brake. i tested the drive, start button off, immediately switches to park on a flat street at zero speed. i realized as an engineer that if this happened at speed a fatal accident could occur. ford can remove this risk with a software update to the electronic shifting, leaving the car in the selected gear if the start stop button is depressed.
the truck was being backed into a parking spot ,the trucks turned off i pushed the pedal to start the truck to back up and it propelled into the wall of the establishment that i was going into to eat dinner causing a great deal of damage to the building and my vehicle. my biggest concern is this problem not being looked into. i have a family and we all ride in this truck i would never want to put there lives in danger knowing that this is a problem going on with these trucks.
