Stop Safely Now .........

[rohankumar]

I have been reading about the dreaded Stop Safely now error message that's bricked many a Mach E on this forum. it seemed to me that some of the early issues were related to the 12V battery running low possibly in the Job 1 cars. However most of the recent issues have led full replacement of the BECM module and HVJBC.

I haven't joined the dots to see if there's an underlying thread of the makes, production dates etc. but am worried that we are not very far away from a bigger recall that Ford might have to push because of the bigger issue they are finding. They have been much aware of this issue recently and have ordered replacement parts very quickly for some forum members. I figured I would bring this up to see if others are more clued in on this issue.

There are literally dozens of different scenarios that can throw that message. In my case it was because my car has received a recent OTA and that freaked out the modules somehow. A shut down for 10-15 minutes was enough time for the modules to power down and then reset. That is probably the best case scenario. Worst case.......well, we haven't seen or heard about any of those yet. If the worst that happens is parts get replaced then we are better off than some other companies.

Is the stuck contactor issue appearing on the GT models mostly?

You‘re worried there may be a recall? I’m hoping there’s a recall because it will mean that Ford has found the cause of the problem, which vehicles are affected, and how to preemptively fix it.

"Many a Mach-E".

20? 30?

I'm not worried.

Try well over a hundred? We honestly don't have real numbers, but it's not 20-30. Ford has real numbers.

Would you much rather have the root cause identified and fixed pre-emptively or lose access to your vehicle at the worst time in the middle of something critical? The issue seems to be growing every week you get on this forum and isn't strictly limited to early models. The only reason I am concerned is because Ford dealerships don't really know their right hand from their left and vehicles could be stuck in the endless wait cycles pending this open issue.

This. Also, I would think one should state that they are not particularly worried that it will happen to their car. However, if 100 cars of the model have been afflicted with something that bricks the car, and requires the entire HVB to be dropped out of the car to have modules replaced, and let's say 35,000 have been sold in the US, you are getting close to 3 percent of these cars getting bricked in the first year of them existing. I'd say that's pretty significant.

We don't have a root cause for HVBJB failure available yet, hopefully someone in Ford Engineering knows what's causing it and is working on a fix. We can only guess the cause since we can't examine the failed parts. Best case it's something that can be prevented with better software, worst case it's a part durability issue that cannot be fixed preventively and we will have to deal with the failures when they happen. At least it doesn't catch on fire like other cars. Anyone experiencing this issue should make a NHTSA report which may help speed release of a relevant TSB or recall.

That's 0.3%, not 3%.

You might want to revisit percentages. If the number is actually close to 100, that is still less than 1% of 35,000. (100/35000=.0029)

I stand corrected, missed a digit. Tired.

I'm not downplaying the issue. If it happened to me, I'd be pissed. But I'm also not worried about it.

But people read forums like this without understanding some basic things.

First, forums are generally for people bitching about something. People don't go to forums when the world is all flowers and butterflies. They go to either solve a problem or bitch about one. Of course there are the "enthusiasts" that go to forums to discuss monitoring things like frunk temperatures to the 3rd digit too.

Second, this forum is a fraction of Mach-E owners. There are ~10,950 members. Let's assume 100,000 Mach-Es sold worldwide. That's about 10% (which is very high). But still only 10%. If there are 50 posts about dead cars (I don't think there are), that's 500 across all vehicles made, or 1/2 of 1%, which is even higher than was posted prior.

I'm sure some people have contacted the NHTSA to report the issue. And they should - https://www.nhtsa.gov/report-a-safety-problem#index By doing so, it allows both Ford and the government to watch this issue. Don't rely on the fact that it's at the dealer for the problem to mean that the failure is properly categorized. Report it to the NHTSA.

Somebody once said that if alien anthropologists ever tried to understand Earth technology by reading about it on forums, they’d quickly conclude that no human company had ever built anything that worked.

This post is confusing. You seem to admit that forums have a (huge) selection bias for people who are having problems (true), but then try to imply that the forum membership is 100% representative of Mach-E owners and total failures would be proportional to membership reports.

As an aside, I haven't seen 50 posts about users getting the message (I think there have been more threads about threads where people have the problem then threads with someone reporting the problem...), and there are numerous mechanisms for someone to get that warning (including killing your battery because you left an OBD2 dongle or some other accessory installed).

My hypothetical calculation shows worst case by projecting the forum numbers.

You're only noting 12v failures. Many are linked to HVB-related components, not 12v.
