From SVS to SSN - The Tejon Pass Claims Another Mach-E

[DevSecOps]

Dealership diagnosed the car today with HVBJB Failure and said that they would have a new HVBJB at their location tomorrow.

Unfortunately however, they said that they can't work on the car until the 31st. So, I'll be a while without it.

There's a slight concern about damage caused to the BECM because there was very high voltage passing through the BECM as I documented in my original post. The dealership said that they will diagnose that once the HVBJB is replaced. I really hope there's no additional damage as I'm sure that would mean another part that has to be ordered and another couple weeks for repair.

I'm trying to stay optimistic even though I don't feel the highest level of confidence.

This is the dealership that Ford Corporate wanted the car moved to, right? ?

That does seem to be a pretty crazy delay considering that the part will be in tomorrow. I guess that dealership must be busy with a lot of EV-related work and/or only has 1 EV tech and they went on PTO?

Regardless - Fingers crossed that the BECM isn't damaged.

I'm going up to Monterey Car Week next weekend in my GTPE. I was planning to go up the Grapevine and cut across Pacheco Pass both ways. I usually take that route rather than taking the 101 to get up that way. Wish me luck.

BTW, my car started production on 4/20 and was deemed built on 6/17. I was one of the April GT builds that was held up for two months. So I have a Schrodinger's HVBJB. I have both the lean and the beefy HVBJB until we open up the box and know for sure. I hope I do not have to find out.

Well, did the Grapevine in both directions this weekend. Yesterday, temps in the San Joaquin Valley were as high as 107. I shut off my a/c and I let the all the Toyotas going 80 mph pass me on the left! No WOTs for me (still did the DCFC sessions).

Think there could be a market for t-shirts that say, "I Survived the Grapevine in a Mach-E GT."

I am glad you made it!

I refuse to baby my car. It is too much fun. I would have kept up with the 80 mph crowd, and let faster traffic go by, as I normally do. But again, glad you made it!

Going up the grade was the only time I made a conscious effort to stick around 75. On the valley floor, I was totally going with the flow of traffic. But since I was on the 5, I was on vigilant CHP alert.

If Ford is already involved, and they sent your car to this dealer, shouldn't they be actively doing something to help this along? And, wouldn't it make sense to proactively order a new BECM rather than pay for two battery removals, reinstall, all the coolant work, etc? Or, did they fire all the people who might actually doing logical things here? Doesn't California have a lemon law time section? This is becoming a circus.

And, how goes the COVID fight?

Is this one of the dealers who only has 1 tech that works on Tuesdays and Fridays like mine?

The repair shop in my body has completed the work successfully.

So today it was the service supervisor who called me and he said he took over my case because of the fact that there's a lot of people involved from corporate. He said he knows all too well that people are breathing down their neck, but fair is fair and the 31st is where I fall. I can accept that.

And, wouldn't it make sense to proactively order a new BECM rather than pay for two battery removals, reinstall, all the coolant work, etc?

This is the part I'm slightly concerned about. If someone had P0AA6 normally it would be reason for concern. It's thrown by the BECM when voltages are wonky, which I can prove with logged data was in deed the case. What would really upset me is if the BECM is left without replacement and it fails while in motion. I'm going to send off an email to the dealer and a few other people expressing my concern about the voltages and if they say it's okay to ignore then at least I'll have documentation that I addressed the concern.

California has one of the strictest lemon laws out of any state. 30 days is the time needed to be without the vehicle.

I hope the bill wasn’t exorbitant. ??

Did they say that maybe you should not have driven the 120 miles after the SVS appeared on the dashboard? I drove only 1 mile on mine so maybe no damage to BECM?

If Ford wanted us to stop with HVBJB failure (post recall) then the appropriate fault would be Stop Safely Now. Service vehicle soon doesn't = don't drive.

I had no choice but to continue the drive. The only other option was to go immediately to a dealer and try to get a rental in Bakersfield which is about 4 hours south of my house. I think most people would continue the drive in an attempt to get home. If they tried to blame me for driving the vehicle I would have probably risen above my "nice guy" threshold.

It's about power draw. It has nothing to do with drive modes. End of story. Driving on whisper will not make any difference in HVBJB failure. As a matter of fact, Scoopman, on the exact same mountain pass was driving in whisper when his went out. There's nothing, zero, zilch, nada that whisper does to reduce power draw over any other mode.

@TheSeg the aforementioned also applies a little to you. You have an RWD vehicle so therefore you draw 1/2 of the power through the HVBJB as someone with an AWD or GT version of the car. The likelihood of an HVBJB failure on RWD is probably something close to 0.1%. I wouldn't stress it much with RWD. Also, LA is a huge area with probably close to 100 dealers. If you ever did have failure just ask to ensure that they are EV certified.

I was indeed in Whisper mode when Tejon Pass claimed its first victim. We have it in that mode on long road trips only because it makes the GTPE Magnaride suspension a little cushier.

@TheSeg I would avoid the "taco stand" dealership I went to, Bob Wondreies Ford in Alhambra. They did change the HVBJB properly (with a field engineer helping), but their service advisor was really bad and they never closed out my paperwork, or properly filed to have the recall software marked as done.

The real question is whether anyone would be safe on the Tejon Pass if they had the ballast of a buckwheat pillow on-board.....

Sounds like we need to make a thread of dealers who “know what theyre actually doing”… “have appropriate staffing” … “have done a replacement”…

It should be searchable by region / area ....

 

[scoopman]

Any MME built after May 25, 2022, has the updated HVBJB installed.

The real question is if the updated part is the answer. I had a HVBJB failure in May at 6,000 miles and I am now close to 12,000 miles and the service vehicle soon message came on yesterday with the HVBJB error codes added by the latest recall. In May I allegedly received the updated part so time will tell if I now have the same failure with the updated part. Right now it is just too early to tell.

I have already given DevSecOps the information, including the previous repair order showing the parts used so I know I am in good hands. He and the others on this board have been beyond awesome helping a lot of us out when it comes to problems. Once I know a little more this week I will start a new thread documenting the repair just like I did the first time around.

This is the most concerning news I've heard ..... as I remember they said you had the new HVBJB part. Confirmed?

Did you get a SVS -- or a SSN?
