I’ve discovered a repeatable glitch with the Blue Cruise in my 2023 F-150 Lightning Lariat, it is reading signs other than speed limit signs and jumping around accordingly. Anyone else?

The first time this happened, I was on cruise at 35MPH going through a residential area when it suddenly jumped to 80MPH. And you know how fast these things move. I almost ran someone over. It has happened to me 9 times since and I finally figured it out. In PA we have these white state road signs, small - like 8” x 5” - that have the road number along the top, and then a mile marker in increments of 10. The Blue Cruise is scanning these signs and reacting as though they are speed limit signs. It works in the reverse too. I was on the highway, going 70, when it suddenly dropped me down to 30. I almost got rear ended. This has been going on since day one off the dealer’s lot.

Recently, it also took me across a very well marked double yellow line into oncoming traffic. I had to wrench the wheel with more force than I would have expected, to get back into my lane. The next day, it did the same, but crossed the white line on the shoulder and almost dumped me in a ditch. Same thing, had to use excessive force to wrench the car back into the lane.

Anyone else experiencing this? I can’t possibly be the only one.

Blue Cruise has never crossed any solid or dotted lane lines for me. Are you sure it is saying you are hands-free when this is happening?

You are referring to two distinct parts of the ADAS, maybe more. The speed limit sign reading can be turned off in setting. Yes, it uses OCR and doesn't seem to be backed up by a "Could this speed limit really be 80 or 85?" reference table. It has troubles with sixes and threes. I keep my thumb close to the dump/resume button. I spent a couple of months with it turned off. Then, I enabled it for highway driving and fight it around town.

The other part about lane departures and line crossing may be as above that you weren't in Blue Cruise Hands-Free. Or, even in a regular Blue Cruise zone or non-hands free BC had disengaged due to construction or unfamiliar territory, which may be indicated when you mentioned there was oncoming traffic. BCHF is not available on anything but limited access highways.

Take OFF the "Read speed limit signs" in the Blue Cruise options. I had similar reactions & quite disturbing. You can leave the speed limit warning option on.

I ran into something like this in Florida shortly after getting my Mach E two years ago. The system has improved but is still fallible.

@Voltz and others have addressed the fact that you can turn off Speed Sign recognition in the settings. Since this is repeatable, I suggest you first go through one of these areas and then send Ford a report from the truck using the report issue feature.

It would also be good if you can capture that on video to post here tagging @Ford Motor Company.

IIRC Blue Cruise Hands Free does not operate where there are double yellow lines. Did it try steering you there while you were in Blue Cruise Hands-on or were you not holding the wheel?

Please remember that these are ADAS (Advanced Driver Assistance Systems). The driver is still responsible for the operation of the vehicle.

Blitzen,
Where in PA are you? I'm an hour outside Philly, wondering if any roads around me.

I don't think I said I was in hands-free mode. It only goes into full on "hands-free" when in areas that support it. I'm new to Ford so I may be mixing up terminology. I have Blue Cruise. Hands-Free seems to be a subset of Blue Cruise (as it was originally explained to me). My subscription just expired overnight last night, so now I've learned it also has just plain old 'cruise control' as well. The speed issue does happen even in hands-free. The crossing the lines happened with "blue cruise" on, but not in "hands free" mode.

It's all moot now as I'm one of the many whose vehicle disconnected itself from Ford Pass and I am unable to reconnect to the vehicle and it would appear in order to re-up my Blue Cruise subscription, I need to do it through Ford Pass - and I can't, because, you know, it won't connect to the vehicle. I called Ford and the FP disconnect is a known issue with lightnings produced at the end of 2022 and they don't expect a fix until June. SO much doesn't work without FP. It's incredibly disappointing.

Sometimes my truck reads the speed limit on a frontage road when I'm on the freeway. I definitely have that setting turned off. I'll set the cruise speed, thank you very much.

I've had a great experience with Blue Cruise so far, even in stop & go traffic. I love it and I'll keep using it. The only "incident" I had was when someone cut me off hard. The truck reacted correctly. It quickly slowed down etc and asked me to take over. But I saw the cut-off coming before the truck did and I would have avoided the emergency maneuver.

 

[Voltz]

re-up my Blue Cruise subscription, I need to do it through Ford Pass

The good news is that it probably has not expired. It should be good for the first three years.

It says on ford pass, expired. Ford rep said expired. I agree, I thought it was valid for 3 years. But that is the frustration - I can ask service, sales, ford and get 3 different answers. I’ve gotta find that thread on reconnecting by removing the (-) terminal and pulling that fuse and see what if that gets me reconnected. Then I’ll tackle the rest. Thanks!
