Our trip (Select SR RWD) to Monterey Bay was the first weekend of June (mid-90s on the way up midday and 80s at night coming home), no issues to report going through Grapevine.I wonder if ambient temperature or battery size plays a factor in this failure point. I made a similar Bay Area to LA on I-5 trip in late March and did not have any issues over the Grapevine at night. I have a SR AWD and made multiple DCFC before and on the Grapevine:
1. ChargePoint DCFC near Wheeler Ridge Road to get to 80% (right before Grapevine). Left at 8:04 pm.
2. Caltrans Lebec rest stop DCFC to get back to 80% near Tejon Pass. It’s free, albeit slow at around 50kWh. Left around 9:15 pm
I was using 1pd on the drive, and I did put the MME in neutral during part of the steep decent into Castaic to see how it would affect my speed (“Officer, this was a scientific experiment”) so perhaps that prevented any problems with the HVBJB. As the SR HV battery has lower maximum output than the ER HV battery, perhaps that also prevented any issues?
Have anyone else has issues with their MME on southbound I-5 over the Grapevine?
Are there any known cases of the pre-update bricking or post-software neutering after a HVBJB failure occurring with MMEs that have a standard range battery?
Scoop - sorry to hear what you've been through. Hopefully Ford will right this with the new updated part, otherwise this is going to get very very ugly soon.
