2021 Ford Expedition: stuck in gear or won't shift

Filed Oct 19, 2026 · Transmission · SC

While driving at highway speeds, specifically during sudden acceleration and lane-change maneuvers, the vehicle experiences a severe dynamic mechanical binding event. The transmission briefly forces a sudden "halt" or engine-braking downshift, causing the vehicle to unexpectedly slow down in active traffic before entering a temporary limp mode. This sudden loss of propulsion and unexpected deceleration creates an immediate rear-end collision hazard on the highway. This happened to my wife while merging onto a highway almost causing an accident. Diagnostic and Mechanical Verification: The vehicle was taken to an authorized Ford dealership for evaluation. The dealership officially scanned, verified, and documented diagnostic trouble code P0786 (Shift Timing Solenoid "A" Range/Performance). Following an advanced diagnostic review, the certified Ford technician officially diagnosed a failed transmission park solenoid (parking pawl solenoid). Direct Relation to Active Safety Recall: The component failure (park solenoid), diagnostic code (P0786), and severe dynamic highway-speed binding symptoms are identical to the safety defects outlined in Ford Safety Recall 26S48 (the federal safety agency Campaign 26V402). Reason for Filing / Manufacturer Action: Despite an authorized Ford dealership verifying the exact failure mechanism of this active federal safety recall, Ford Corporate are currently refusing to cover 100% of the repair costs. They state that my specific VIN has not yet been "activated" in their database due to Ford’s phased tranche rollout schedule extending through 2027. I am being forced to pay out-of-pocket for an active, dealer-verified, federally recognized safety hazard. We cannot drive the vehicle with this significant safety risk. I am paying mostly out of pocket to cover the repair.

I am filing this complaint because I truly believe this transmission issue is a safety problem. I was driving my 2021 Ford Expedition and was merging onto a busy highway when I pressed the gas to get up to traffic speed. Instead of accelerating, the engine revved but the transmission would not shift. It felt like the vehicle was stuck between gears or in neutral. My SUV would not accelerate when I needed it to, and I remember thinking, “This is how someone gets hit.” As a mom, it was terrifying. I depend on my vehicle to safely get my family where we need to go. When you press the gas while merging into fast-moving traffic, you expect your vehicle to respond. Mine didn’t. I was left trying to merge while traffic was approaching and my SUV would barely move. Before this happened, I had noticed increasingly harsh shifting and delayed gear changes. The vehicle had been properly maintained, and the transmission had recently been serviced. After the incident, an authorized Ford dealership diagnosed the transmission with a failed CDF drum in the 10-speed transmission. The transmission had to be completely rebuilt. After researching this problem, I found many other Ford owners reporting the exact same failure and the same scary symptoms. This doesn’t seem like normal wear and tear. Losing the ability to accelerate without warning is a serious safety concern, especially when merging onto a highway or crossing an intersection. I hope the federal safety agency investigates this issue before someone isn’t as lucky as I was. I was fortunate to avoid an accident, but I can’t help thinking another family may not be.

Vehicle loses acceleration. When I attempt to pass someone on the interstate, the vehicle does not accelerate. When I push the gas the engine revs, but does not engage. I have to take my foot off the gas for 10-15 seconds for it to go back into gear. Error reads "stuck in park". It has been to Ford numerous times with the same result, they can't duplicate the problem.

Daily the automatic transmission will erratically and forcefully downshift at highway speed. When changing Driving Modes the transmission display on the dash has numbers disappear and the transmission downshifts with great force which has lead to injuries. After sitting for more than a few hours the transmission will not go into reverse at first but will then violently shift into reverse after several minutes. These issues began not long after we purchased this vehicle new. The service manager at the dealership the vehicle was purchased from when I told him about these problems told me that I don’t understand how a 10 speed transmission works. Sometimes the driver’s seatbelt will not buckle.

For the 3rd time attempting to pass other vehicles our transmission revved up to almost 5000 rpms and would not shift after making a huge clunking sound into an obviously to low gear. We had no power and the vehicle would not accelerate. I do have a video after the clunk sound but can't upload it.
