2023 Ford Maverick Hybrid: adaptive cruise control problems

Filed May 4, 2025 · Driver assistance, Engine · TN

While traveling 80 MPH using cruise control, the vehicle speed suddenly reduced and several warning lights illuminated. The three warnings were Pre-Collision Assist Not Available, Service Engine Soon Warning, and Powertrain Malfunction / Reduced Power. The accelerator pedal did not work but I was able to coast to the nearest exit. I stopped, turned the vehicle off and back on a few times but the warning lights would come back on. When I shifted the transmission into Drive the vehicle would take off on its own. I drove the remaining 30 miles just letting the vehicle accelerate on its own because the pedal did not work. It wouldn't accelerate over 35 MPH. The vehicle would still pull when I applied the brakes. Once home, I turned the vehicle off for an hour. When I turned it on the warning lights no longer illuminated and the vehicle drove normal.

On [XXX], I was driving home on [XXX] in Rocky Mount, Virginia. The truck lost power; the Drive Shift knob light was flashing, warnings started flashing, hill start assist was not available, service vehicle soon, pre-collision assist was not available, service advance Trac and parking brake applied automatically, and total loss of power. The truck came to a stop in about five seconds. I stopped, turned the truck off, and restarted. When I let off the brake and did NOT press the gas, it would start to accelerate all on its own up to about 28/29 mph, acting like it was in cruise control. When I pressed the accelerator pedal, nothing happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

[XXX] car malfunctioned in same ways it has been before. Car was going 76 on the highway, no cruise control, when a message about the gear shifting pops up and the accelerator stops working. Car begins to slow, and we pull over onto side of the highway. After getting down to about 40 parking break pops on and messages begin flashing through on the display saying: AdvanceTrac Off, Collision Assist Off, Parking Break On, Service System Soon, and all the warning lights such as check engine and slippery surface come on as well. Turned car off and waiting 5 minutes, then got back on highway. Car repeated this exact same process again after driving 3 more minutes going 76 with no cruise control. Here is a link to a video taken the first time this happened on this day: [XXX] Car had been taken to have this exact issue repaired the previous week and held over night on [XXX]. This is the second time that the car has been taken to be repaired for this issue. The first time I was told it is a computer melt down. The second I was told that the recalls that they fixed they did not fix entirely, and that it should be fine now.

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.

This morning I was driving to work (65mph cruise control, 45 degrees F outside, heated seats ON), out of nowhere I felt myself slowing down right after I went over a railroad track (pretty decent bump) on the highway. As I was slowing down I noticed that my cruise control had turned itself off and when trying to turn it back on (pressing set+, set-, and the toggle CC on/off button) it wasn't responding. After realizing that setting my cruise control wasn't working I tried accelerating on my gas pedal but nothing was happening and I was still slowing down. I tried again and noticed that when I accelerated, the needle on the left side gauge wasn't going past the green battery section even when accelerating harder than normal. Everything in the vehicle seemed to be working properly as far as power steering, lights, breaking, dashboard, etc. Eventually I pulled over to the side of the road, put it in park, put it back in drive, and everything was fine for another 70 miles on the day.
