2012 Ford Expedition Complaints

Transmission failed to engage after startup, and while driving will slip out like its in neutral without warning. There was a series of messages that rolled over and over as the vehicle slowed. When we first took it to have it serviced for this problem June of 2024, they optioned to flush, change the filter, and put in new transmission fluid. They could not reproduce the problem. That seemed to take care of it until May 17, 2025 when it started slipping again. Again, the service center cannot reproduce the problem. The sudden slowdown, puts us in a risk for an accident with other vehicles. The vehicle is available for inspection if needed.

While driving my vehicle, the transmission down shift on its on and the vehicle antilock brakes hit and suddenly stops on its on.

I was traveling [XXX] in Logan Co., OK in my 2012 Ford Expedition EL (purchased used Jan. 2020) at an approximate speed of 45 mph when the vehicle downshifted into 1st gear causing a rapid deceleration wherein the vehicle behind me had to take evasive action to avoid rear ending me. The engine rpms climbed significantly while the speedometer stopped working and the vehicle never shifted into any higher gears for the next five blocks wherein I was able to pull my vehicle into a safe place. Again, the vehicle continued only in 1st gear! After turning the vehicle off and letting it sit for a few minutes, it appeared everything had reset and I slowly drove it straight to my mechanics shop. (However, shop was closed until after Memorial Day, so I again drove it slowly back home). Total trip was approximate 12 miles. Issue took place approximate 5 miles from when I left my residence. Ironically, I had visited my mechanic the day before inquiring about an issue wherein...

The transmission jumps in and out of gear, the engine revs on its on. I was on the highway the first time and I going between 60 and 65 mph and it sounded like the whole bottom of the truck was just ripped out, the truck went from drive to either park or first gear it locked up the back tires and there was a truck behind me he tried to miss me but he hit the back passenger side of the truck. He was very very upset he threatening and cussing me because he thought I just slammed on my brakes for no reason. I explained to him what was happening and calmed down think God. It could have killed him or me or even several other people. When it locked up the tires then it jumped back in drive and tried tot take off, I threw it in neutral and cut the key off. That scared the sh.. out of me!! I have talked to other people that have around the same year model truck as mine and some of them are having the same issues with it jumping in and out of gear not wanting to shift gears revving up on its ow...
