HVBJB means what?

[mkhuffman]

It was five failures, but who’s counting ?. However, I am a very unusual case sine I spent most weekends out in the country on open roads with lots of WOT opportunities and some were coming out of turns on pretty good upslopes.

As I mentioned on my previous thread, engineering was so interested in my case I agreed to have a data tracker installed and spent 7 hours out in the country showing them the routes and giving them all the background data so they can continue looking for a solution. I will tell you I got the impression they are still very committed to getting this issue solved. How soon that is of course remains to be seen.

Maybe they need to put a monitor in my car to try to figure out why mine has not failed. ? 32k and I stopped worrying 15k ago...

Best news I have heard, Ford should be made to do a proper recall, my fear though is since they are not sure of the fix it won’t mean anything. I would still take a new more “robust” one.

Firstly, I find it hard to believe with today’s technological advancements that the 5 contactors still consist of crude mechanical contacts which make/break electrical flow and so inevitably creates arcing each time and so also inevitably heat & degradation of the contacts.

It’s plugs & points technology, remember that? And those contacts - the points - were replaced routinely during servicing as a matter of preventative maintenance.

Then it seems hard to believe that a company that fits a part not up to the job is allowed to alter the job it does by effectively altering the originally now misrepresented specified performance and leave in place a part which is still prone to fail and not up to the job if that’s the case..

I think your US NHTSA are more likely to enforce an alternative resolution which will include replacement of the contactor if they deem that as an essential resolution.

UK’s DVSA are another kettle of fish, however, because UK’s Safety Recall system is voluntary and I expect DVSA, even if NHTSA make Ford replace the part in US, will allow Ford to argue and distinguish between what is the same fault in UK and that in US.

Twas ever thus, though, has happened a million times before and will continue to happen as sure as eggs is eggs??‍

I'll say this. I know for a fact that NHTSA investigators are looking at the issue again. I also know for a fact that they are considering additional actions against Ford and the issuance of an expanded recall. If any of that will come to fruition I have no idea, but they are looking into it still. This was as of 2 weeks ago. So, if NHTSA was satisfied with Ford's response and "fix" they wouldn't still be investigating like they are. Ford and NHTSA know that there's still a big issue.

Maybe this is how the 5 second limit gets "changed."

Also, HVBJB is pronounced "heebiejeebie" in case anyone wondered.

OK, now everyone after this one be funny.

Highly volatile b*tch just borked (again)

I bet 4 seconds would save some GTPE HVBJBs

Agree, it is hard to believe a mechanical relay is used for such a highly critical design.

Last time I designed electronics circuits using multi pole relays was back in the 1980's for the motion picture field.

Then we switched to SSR (solid state relays) which were more reliable and does not arc nor spark during switching which made them ideal for use in hazardous/volatile/flammable movie production locations.

SSR lasted forever and the only way it would fail is to exceed maximum current (wattage) which would of course melt the solder joints too...

Thank you for posting this link. I feel like I'm reading a foreign language when the acronyms start to fly on some of these posts!!!!

Thanks for this piece of information.

This is to remind everyone who has this issue (or other issues) to report it to NHTSA.

This is one of my biggest pet-peeves about this forum. Where do those people supposedly get their data? The answer - they don't. They make up claims to push their agendas or because they own stock in Ford or some other strange reason. It's like they are married to Ford and ignore all actual data.

I agree, data.

Clearly HVBJB happened, significantly.

My question is simple: for 2023 model year VINs, have there been failures? What would the data show us about estimated failure rates? Not as interested in pre-2023 VINs or what happened 11 months ago and the replacement parts in those - the fix could have been more complicated than the single part. I mean, it's fascinating reading, but selfishly for those thousands of '23 VIN cars on the road and my personal, that's the info I'm interested in.

We also have the rumor that GTs were effected to a greater extent. Splitting out the '23s from GT, AWD, RWD, might show difference that's significant.

My reading of all of those past threads was a change at the factory that was fully applied in 2023 MY cars. I had thought that had solved the problem, but I am willing to be informed otherwise.

If you have this data, or a known set of VINs, I'm absolutely willing to be proved wrong. Or would even be willing to DM and share dataset - I am not unsophisticated in data analysis. Not "happily" proved, of course, but it's better to be armed than unarmed.

[ As someone who owns a porsche with the dreaded IMS misdesign, and previously the Saturn engine known for running dry on oil and freezing, and a Honda engine known for leaking gas into the turbo lubrication system, I am aware "these things happen" and it is best to know your car's design flaws and and avoid behaviors that become known-risky after the fact. ]

The problem is that nobody outside of Ford has a reasonable handle on the data and they’re not sharing that data set. ??

Newb here. Can someone please decode the acronym HVBJB? I've searched the web and can't find out what all those letters stand for. Thank you.

I have a 2021. Is this something that should be replaced and covered by warranty?

I don't know what it takes to run a check on FDRS, but can a bunch of 2023 VINs be run to see if the heebiejeebie has been replaced or is throwing an error code? Could you generate a bunch of 2023 VINs in the first place? Would Ford shut down FDRS if people started uncovering the dirty laundry covering the skeletons in the closet?

People keep missing the "part to part variation" line they putout, some parts are ok, some are not...

If it fails, yes.

Only if it breaks. You should have a software "fix" that is supposed to let the car still drive with reduced power if it detects something is wrong with the contactors. Might wanna ask a member here if you've got that applied already, you probably do.

Do you want a job…………at Ford?
