"Sorry, officer. Just part of my car's recall."
That's what they said about COVID...
Why?
I've already spent half a day waiting for a tow truck, getting it towed, driving back to drop off the key fob from the dead 12v and bad BECM. After that much hassle a software update like this makes triggering the problem a lot more enjoyable or at least as enjoyable as it can be. Of course if the 1% to .5% failure rate is correct then maybe I'll never see it and just have a lot of super fun drives. If they lied though then let's just hope I trigger it before the warranty expires...or since it's a recall I guess warranty expiring or not I'd still get the new part replaced free of charge if it fails after 8 years or 100k miles or whatever it is the extended warranty covers (yes I was one of those buyers)?
Considering that the car is severely limiting the power output when this happens, I assume even if it will let you DCFC, it will be at a reduced rate. If this warning is in fact a warning of impending catastrophic failure of the HVBJB, I wouldn't want to DCFC on it at all anyway since that seems like it would likely trigger the full failure.
I'm so sorry to hear about this happening to you multiple times now @scoopman. I'm glad to hear you and your fam are doing well. Thank you for sharing these details to keep other MME owners aware of these issues.
it is an interesting question if lowering any regen as much as possible might reduce thermal and electrical loads. I might do this when descending in the future. Does anyone have facts on whether turning off 1pd might reduce any levels of regen on a steep descent?
i believe this component is part of the powertrain warranty on he MachE which is 8/80k without any additional warranty purchases
you can totally do that but it will use more energy to run car systems and so the Hvb will charge slower. Not sure this matters at all wrt thermal and electrical contactor loads but if you do have a stuck on condition already this might be the more safe course of action.
I’ve driven all over Palm Springs area in our ID.4 and that is a hard core drive from Bay Area all the way to Joshua tree especially without any of the software recall protections and warnings, as minimal as they are. I wouldn’t touch doing that drive with what I know about how underspec the partreally is.
FYI There have been just as many reported problems with the ID.4 (mainly battery coolant pump) as the Mach-E's HV junction box. Sorry to hear you are having issues with the MME but it doesn't mean the ID.4 is perfect.
The HVBJB isn’t part of the recall. The recall is software.. 8y/100k is pretty much what we get on the HVBJB unless the physical HVBJB gets recalled. ??
Real bummer to hear for you, yours and everyone here. Hope they do not start failing with great speed or many maybe sitting for months waiting for parts. No worries misery loves company
. Looking like it is not fixed.
