In all of the Fords that I have owned the “Pre-collision“ senses and alerts visually and audibly. I do not drive aggressively. I have had some extremely close calls and nothing happens, no visual, no audible, no braking, nothing, Recently after picking my vehicle up from the dealer for these issues (no error codes), on the highway, I was forced almost into a wall due to a driver not paying attention and swerving into my lane in front of me 12” off my bumper. I had no time to brake, I had to maneuver away to avoid a collision. Backing up in a parking lot and a car zooms past, no braking or signal, etc. I can list many more times where it should have at the very least alerted me. Could the 3 radar sensors be the issue???
I own a 2020 and in that year, you can turn the pre-collision feature off in the settings. When it is on, I personally think it's a little premature in some instances.
If I am in reverse, I get a cross traffic alert, audibly and visually, if an intersecting vehicle is approaching. If backing up, the braking assist will definitely activate when you get
into the steady beep zone. In fact, it slams on the brakes so hard, it makes you think you've hit what's behind you.
If you aren't getting any of these functions and they are activated in the settings, then you may have a problem. I wouldn't think it's the sensors because that I believe
would show up in the codes.
The control modules in these STs are finicky to say the least. There are so many features engineered into them that it confuses itself.
My Sync 3 can't even handle streaming music from a flash drive or my phone. In fact, I don't even know why it has playback controls because
it does whatever the flock it wants to, regardless of my choices.
These STs drive and perform nicely and they look good. I have a hard time checking any of the other boxes.
