Vehicle loses communication between control modules & goes into a limp-home mode. Has happed 3 times when doing highway speed driving on cruise control. Lots of alarms are posted including forward collision warning, emergency braking & traction control not working. Check Engine Light lights. Vehicle power is shutdown to low level. There is loss of throttle response. I pulled over to side of road because display messaging said that it wants to shift gear but must wait until vehicle slows. When slowing to near a stop, but still going 1-2mph (estimate), the vehicle slammed into park & put the Parking Brake on. I can acknowledge warning messages, take Parking Brake off, & select Drive. Then vehicle tries to move at 35mph of its own & w/o any throttle input. In fact, the throttle is unresponsive in this mode. The electric traction motor and/or engine will try to maintain 35mph -- forward or REVERSE -- &will apply power as needed to sustain that speed. Thankfully, the braking power will overcome the powertrain drive power & I can stop. The communication issue has happened to a couple other Maverick vehicles in the country, but I don't know whether they've experienced the vehicle trying to go 35mph on its own w/o any throttle input. This going 35mph in limp-home mode -- in forward and in reverse, and w/o any throttle input -- is a horrible fail-safe response & seems very unsafe to me. It is hard to gently back into a parking spot. Losing power while driving because of the whole communication failure is very unsafe: I might need to finish a pass on a 2-way highway and would need power for that; I might need to throttle out of a situation; or, as has happened 3 times to me, I suddenly lose power on an interstate highway where traffic regularly is going between 65 -80mph. This could leave me getting rear ended because my vehicle slows w/o brakes applied so other drivers have no warning. These incidences occurred after 23C41 / 23V848 safety recall service.

[XXX] car malfunctioned. First said that the gear was working incorrectly, then accelerator stopped working and Drive light on gear shifter started blinking. I pulled over to the shoulder and the brakes continued to work, and all the messages in my video came up. I started on cruise control going 78 then once I got to [XXX] my parking break came on. Once stopped I tried to go back into drive, which didn't work. The car would not go forward, almost as if it was attached to something. I turned the car on and off several times trying to get the parking break off. After I believe the third time I turned off the car, I left it off for about a full minute before turning it back on. The lights on the car went off except the check engine light, and the emergency brake light, though it finally let me turn the break off and switch into drive. I drove the last 4 minutes home without incident. This links to a video I took after I got onto the side of the highway showing what was happening on my display. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I was driving on a freeway and my vehicle went into "Powertrain malfunction/Reduced power mode " and slowed me down from 65 -70 miles an hours to under 20 miles an hour. This almost cause a semi to slam into the back of my vehicle missing me by inches. The dealership is unable to recreate this issue but confirmed it did happen. Ford and the dealership have been giving me a run around with this since they can't diagnose the issue.
