HELP: "Stop Safely Now" message?

[wrgrimes]

Here is my routine for the "Two Step Start". So far it works.

1. Get into truck and shut the door.
2. Lauch OBDLink and observe both SOC levels and 12 volt amp draw. DC/DC converter has not awakened yet.
3. Press start button with foot OFF off the brake.
4. Observe volt/amp changes as the DC/DC converter comes on line.
5. Clear all the "OK" messages.
6. Foot on the brake.
7. Clear the "OK" message.
8. With foot still on the brake, press the "Start" button.
9. "Ready" light appears.
10. Set AC blower to "5" or more.
11. Confirm 12 volt system voltage at 13.8 to 14.2.

You are good to go.

Monitor your SOC's for the last shutdown of the day. No science here. I like to keep my 12 volt system 90% or above and my 280 volt system into the 50's or 60's. You need more than idiot lights to monitor this truck for optimum operation.

Thanks
I think you get credit for developing the "PowerBoost 2 Step".
I am still wondering if the Clearing "OK" is vital?
What is the mechanism for this working? (I think I have seen some suggestions in the hundreds of post on the subject, but do not recall why it works)

I don't know. And it works until it does not.

There are some smart people here who have speculated why it works (so far). I considered it as a possible work around while watching the voltages move around on the OBDLink. A lot of stuff happens very fast when you just abruptly wake up the F-150 by crunching the brake and hitting the button at the same time. With all those modules waking up together I figured one was probably a little more sleepy than another and simply told the PCM I am not ready yet.

We will see what Ford comes up with but we may never know. For now let's try this and see if it works. Remember the SSN warning is generic. This issue is 2023 based with specific fault codes detailed elsewhere in all these threads. There are other reasons you can get an SSN starting.

Have you tried any of the suggested work arounds? I understand your frustration but we are also trying to solve/prevent this problem. If the suggestions here haven’t worked, please let us know.

Both times I have been able to get it to start by getting out of the truck, locking the doors with the Keyfob, pressing the remote start button twice, waiting a few seconds and then trying remote start again. I can then unlock the doors and it has started. However what manufacturer has the balls to sell you a vehicle with a list price over $83k and then tell you it is not a big deal that you cannot depend on it to start when you need it unless you do a one legged rain dance in the proper direction outside the truck? It is absolutely absurd to have this kind of problem with low or no priority from Ford to get it resolved. Instead I am filing a report with the NTSB and taking the truck into my dealer to report the problem and start the clock on the lemon law.

And you consider this an acceptable method for starting your vehicle every time? Every other vehicle I have owned in the past 10 years was as simple as get in the vehicle, press the brake, push start. The method you describe while helpful to those experiencing the problem is nothing but a work around. Ford should have to train every new buyer on your starting method as part of the delivery of a new vehicle - or better yet as part of the sales process to see how many people would still buy the truck knowing it poses a risk of not starting. I refuse to let my wife drive my truck now for fear she will be stranded somewhere in a truck that won't start. Reliability is what I am after. Ford does not seem capable of delivering reliability any longer.

Well you can now add me to the list. 2023 PB Lariot 6,000 miles. It came on today. I turned the truck off and walked away. Did not lock anything, i was at my house, came back 15 min later and it started right up, key fob stayed in the truck and i used the start button. I keep my truck plugged into a battery tender all the time because i don't drive much and the light on it said it was fully charged when i unplugged it.

I don’t disagree but I don’t do all that (I don’t have the tools). I almost always remote start with the fob or app. If not just press start without your foot on the brake, wait a few seconds then fully start it. Pretty simple. Nonetheless, not something we should have to do.

I think pressing ok to clear out the normal alerts is just a way to make sure you wait long enough to let the software settle out before starting it fully. Not actually required.

In fairness, every other vehicle you ever owned pales in comparison to the electronic juggernaut you are in now. I understand you’re upset but you’re making generalizations that are not true. Ford is certainly devoting resources to this problem, and they are certainly not saying this is “no big deal.” The reality is that dealerships don’t know about this unless their customers bring it to them. Further, the front-facing customer service staff aren’t the top techs who are actually working on trucks. The sales guys don’t even know this is a thing.

On top of all that, to say that ford can’t deliver reliability when the truck literally starts with a different method of startup process is laughable. Ford has a lot of info-gathering to do here and you should consider how lucky we are to have smart dudes who are experimenting with their highly-computerized trucks to diagnose these issues on startup. With all the complexity involved, why is it so crazy to consider pushing start without your foot on the brake and then doing it one more time? Ford will figure it out. The truck still works, still tows above-class, still has speed above-class, and still has MPG above-class.

I spent 86k on my truck too, and I trust that this issue will be fixed with software and in ten years when I’m still driving it this will be an afterthought. Thanks to all the users before me who have posted here this is a blip in the road.

I liken it to issues I've seen in the past with the current generation of DoD aircraft (fighters, attack). The things are so computerized that occasionally a piece of hardware will miss a beat on startup, and the jet will essentially be bricked. Luckily, this happens in the test phase, before the softwrare gets to the warfighters.
The amount of time it takes to hit the start button twice is trivial, IMO. Yeah, it's longer than it takes me to twist the key in my 1997 Wrangler, that starts every time. But then again, my Wrangler doesn't even have Bluetooth anything.

The truck only works if you remember to use the two step starting method consistently. If you forget (out of habit) and you trigger stop safely now, you then have to wait or try some other ritual to get it started. That means the truck cannot be counted on to start. If Ford is willing to train every potential new buyer on the work arounds then buyers would know what they are getting into and could make an informed decision. I would not have made the purchase. BTW my 2021 Ram limited was loaded with electronics and it started every time. My 2023 S550 is also loaded with electronics and it starts every time through the normal start process.

For the second time in a week I have had my truck not start and give me a "stop safely now". I have had enough. A brand new truck that won't start is not in the cards for me. I am starting the search for a replacement.

New development for me, now I get an error that 'remote features are disabled to preserve battery'. Not sure if this is at all related to the SSN or not. When I power the truck off, I get a 'system off to save battery. Please turn ignition off or start engine'. Well the ignition is already off...so it seems pretty confused. The warning chimes sound different now, no approach lighting working, etc. Surely it doesn't need a new battery after 4800 miles. So frustrating.

Not related. (in my opinion)

Bet your 12V battery static voltage (SOC) is below the threshold for supporting multiple features. Remote Start being one of them.

 

[Snakebitten]

I wonder if Ford were to program the Powerboost to have a 10 second, or even 5 second delay in the time you "start the truck" (push the button) and you get the "Ready", if there'd be a bunch of ranting?

I honestly don't think there'd be much.

But manually inserting that 5 seconds ourselves? It can get some folks pretty fired up!

So probably a battery replacement? I drive it multiple times a day so its not sitting off for long periods of time.
