October 2022, the 30th I believe…weekend right before Halloween
hmmm, you should have the new-design HVBJB, and very low mileage, so that's an interesting outlier perhaps. You didn't do your first 1700 miles in a hill-climb rally race, right?
Haha no, a very ordinary, boring 10-20 mile round trip commute, Mon-Fri.
Hmmm you might want to read your diagnostic codes with an OBD reader to know what you're dealing with here.
Same as Scoop recommended just before your post: if you have an OBDII scanner, read the codes and see if what they say. It is possible there is another cause, and the SVS message will go away the next time you start the car. If that is what happens, it is very unlikely caused by the HVBJB.
Agree with your comment but the difference here is they have the old HVBJB while the previous commenter has a fairly new Mach. Hopefully your advice works though. 9,200 miles and ticking for myself.
Think it's time to get an OBD-II scanner off of Amazon and see what codes you have -- old-part HVBJB damage doesn't require you to drive like future Ford-powertrain sponsored Max Verstappen to have it fail. Just changes in temperature with outside charging can build up damage....
Just got a call from the service writer - they diagnosed the problem Tuesday morning when I brought it in, had the new HVBJB in yesterday morning and installed, and gave it a night to make sure everything was good before calling me. It's ready to be picked up. SVS on Monday evening, shop on Tuesday, fixed before lunch on Thursday. I'm impressed.
I really expected it'd be 2 weeks - especially since when I was setting up the appointment they informed me it'd be 1-3 days before they could run a diagnostic on it. When I got the call today, I expected they'd tell me they ran the diagnostic and were going to order parts. I was shocked when he told me it was fixed up and ready for pickup. I immediately asked what they did to fix it expecting that he'd say they reset something and he told me they'd replaced the HVBJB and told me they'd ordered it day one, had it day two, and tested it this morning.
I just get experienced the exact same issue - faulted while charging and then SVS. I drove it and later when I started it the message was gone. Drove home and plugged in, normal charge session. I connected my ODB scanner after the fault cleared, there were several codes related to power faults, all in archive status. I’m guessing if I bring to dealer in this state they won’t be able to do much. Keep driving until it faults again? Until SSN/turtle?
