2 Days with a 2023 GTPE before HVJB- what's the record???

[mjkeen51]

Well it was a fun two days. Ordered my Carbonized Grey GTPE early March, took delivery Aug. 3. Was everything I hoped for. Ride was great, acceleration was utterly unreal, bluecruise worked like a charm. We took it to a family graduation party on day 2 (185 miles away). A little after we arrived I swung by the Tesla Magic Dock supercharger up the road from my in laws. The location and future addition to the network would have really been super convenient since we visit a few times a year.

After charging up, headed to the party store for balloons, drove some backroads with my brother in law. It was a spirited drive, wanted to show of the unbridled mode in a performance edition GT. When we got back out of the store, an hour after charging, had both the High Voltage and Power train warning. Was able to limp home barely with the SVS messsage, left the car in the garage for a few days, backed in of course in case turned to a brick. My dealer (who has handled the situation very well so far) was able to get me in, set up with a rental, and looked at by their EV specialist. They confirmed today it is an HVJB issue and will need to replaced, seems like this might be a record (<400 miles on a 2023).

Working through the process to return the vehicle, we planned on using the car for enough long distance trips for family and kids travel teams that not knowing if the car will make it back home after another SVS message just isn't really viable.

Thanks for those that gave advise over the last few days. Appreciate the info on this forum. Hopefully Ford figures this issue out becasue the car really was quite amazing.

Yikes....

I do wonder though....is Ford being too aggressive with their sensitivity in measuring the resistance at the connectors? Are they really failing, or just reading higher resistance when temps increase even though the new connectors resist welding shut to a higher degree?

Sorry this happened to you. I’m not sure what the record for a failure is, but there was a defective one that died right outside the dealer’s driveway. You may either be the quickest failure or darned close to it. ??

I think that one was for a replacement HVBJB... no doubt the owner will see this subject title and chime in.

Looks like a in dealer replacememt recall is needed. Too many failures. FORD defect!

A replacement recall won't do any good if the new ones are just as at risk of failure as the older ones. I do hope they're taking every single one of these that fail back to analyze to find what it is about them that makes some more prone to break. There are many out there running just fine, so there must be some small subtle difference, that they hopefully can find.

Just got my GTPE, 1000 miles this week, 4 DCFC, a bunch of full throttle events. No issues. My old Premium had a HVBJB failure it was 4 days in the shop. If it happens to this one I will survive

Dang sorry that happened man.

Still haven't figured it out and it's been over a year?

At this point, HVBJB failures are simply unacceptable. Failures on a 2023 are beyond unacceptable.

This is back to my question though....Ford changed the programming to measure resistance at the contactors to initiate a SVS BEFORE it fails...because the resistance jump suggested a risk of welding shut.

But as temperatures increase, resistance increases...I'm assuming the temps under these driving scenarios would be the same between the old HVBJB and the new HVBJB....so could it be possible Ford's threshold for initiating an SVS as a known threshold for the old HVBJB prior to failure is too low for the new HVBJB and the SVS is being initiated prematurely?

Are folks actually having a HVBJB failure? Or a false indicator of a failure because the programming is designed to avoid the failure for the old part?

Just spit balling.

Why are ours failing but nothing on tesla. Are they heavy duty parts on the tesla?

As I understand it Tesla has better thermal management of the HV components and beefier internals. But since I have just started my new volunteer position as test driver for Tesla, only time will tell if that is indeed true ?. So far I am only at 2,000 miles since taking delivery 3 weeks ago.

If you start melting parts of your M3, we want to hear all about it!

Absolutely. Like I said, I am not leaving the board here. This is too good of a community not to be a part of.

Plus, I am still really fond of the MME. I will certainly miss it. And I know with how hard the engineering department is working on the HVBJB issue, as well as the other issues that we hear about on the board, I know it is just a matter of time before they have it figured out. You have to keep in mind that Tesla has been at this a lot longer and since they only build EVs, that is where all of their efforts have gone to.

Tesla also has the advantage of having all of their cars so connected that the entire fleet is always sending data back to headquarters. This not only includes all the background data of what's happening internally with temps, error codes, etc., but even sending back videos of the road conditions, external temps (and even interior temps), speed and location. Which, in todays environment of privacy laws and social media pushback on invasion of privacy, is quite remarkable they have been able to keep that in place. The car even asks for feedback when something happens. I have had a couple times where I have taken over when the auto pilot and there will be a message that comes up asking for verbal feed back of what happened to cause me to take over.
