This has happened to me 3 times, I was able to reproduce it. Sitting in line at a drive through, and driving in a parking lot. I don’t think I turned cruise control on (I did for the video to reproduce it) but it’s possible I hit the button on accident while wearing a heavy coat. Every time I’ve almost hit a car or a person because I’m at a stop and I let off the gas to move forward and the vehicle just takes off on me. This is extremely dangerous. I’m really getting tired of the issues with this vehicle.

I don’t understand how hitting cruise control at a stop, 0 mph, arbitrarily sets the cruise control speed to 15 and keeps it “active”. That’s dangerous.

I’m not following the issue?
On mine you have to be going the speed you want to set or going above 25 mph to turn it on. Once it’s on its adaptive and will stop and go.
If you hit the break to stop or slow down it turns off.
Is yours not turning off when your foot is on the break?

It turned on when I was stopped, and set a speed of 15 MPH. So when I let off the brake to creep forward it launches forward after 4-5 feet and tries to get itself to 15 mph. I have no idea why it can get set for 15 mph when you are at a stop with the foot on the brake.

This also happens with the 2018-2021 but it is a two step process: you have to turn the cruise control on, then press the set button while stopped. Never happened accidentally with me.

I’m intrigued, so I’ll try to replicate on mine.

Has this something to do with the 'auto hold' and stop-and go traffic? The radar detect the traffic in front has started moving so will accelerate to keep up.

It sounds like the OP has cruise turned on which is normal. I typically turn my cruise on when I get in so that it’s just one button press to set the cruise once I’m on the main roads. In this case it seems like OP is accidentally hitting the set button on the steering wheel without realizing it. If you have your foot on the brake and hit set, it will default to the lowest possible speed cruise can be set at, 15 mph. Once you release the brake it will attempt to reach that speed. So it works opposite of when you have cruise set and tap the brake to disengage it. In this case OP needs to be mindful, it appears, of what their hands are touching, while completing other tasks in the drive thru lane.

No, there is a single button that turns cruise on and sets at the same time. Pressing this button should normally not set the cruise active while at a stop. I have figured out the issue.

With speed recognition turned on in the settings, it sometimes displays an erroneous “speed” which is just a blank black box. If you hit that singular button on the steering wheel even when at a stop it will turn cruise on and set the cruise to 15 mph. When speed recognition is working correctly and you hit the same button it turns cruise on but does not set a speed, when at a stop.

Whether I accidentally hit the button or not, that is extremely dangerous. Ford has tried to put this fail safe in but there is a bug in the software that allows it to be set when at a stop. I wouldn’t accidentally hit the button probably if I didn’t have to wear gloves in the winter because the heated steering wheel does nothing.
