New Flash Delivered and Now Won’t Start or Shift

[Pioneer74]

Anyone else feel like the person that delivered the truck had a little too much fun "testing it out" on the way? LOL

You should see how the logistics drivers are around the plant. You may baby your vehicles, and believe it's been driven nicely all it's life, but it's beaten like a mule for the first couple of miles. If you saw how they drove them from the plant to the shipping site, you might not buy a new vehicle ever again.

My truck had the same issues. Turned out to be a short in the wiring harness. Tech had to go through it connection by connection. Very time consuming. Fixed and no problems since

UPDATE!!

The service manager has been in contact with Ford EV engineers. The engineer advise them to "reset" the BMS (Battery Monitor Sensor) and then recharge the new 12v battery. The vehicle now starts when requested. The Ford engineer advised to try and re-create the situation and if it fails again, it is probably the HVB. If not it may have been the original 12v being
depleted and caused the BMS to fail or vice versa. The dealership is going take the truck off the charger and leave outside and probably drive it a bit this afternoon. Then let it sit overnight not hooked up and see if the condition repeats tomorrow. If not, I can take the vehicle.

I asked if they would let me see the battery status for both the HVB and 12v before leaving with the vehicle by either being hooked up to their equipment or me connecting an ODBII scanner. They advised that their tech would provide battery info. They said all documentation and notes would be provided.

Being that the selling dealership drove it around their lot without issue, I don't if the issue can be re-created that easily. It may take a long drive that cause something to fail. Only time will tell.

Anyone hear of this type of issue or any concerns/questions that I should address before taking the vehicle (assuming they can't re-create the issue by tomorrow)?

Thanks in advance!!

I would have walked away on this one. Just me. I can handle a few minor cosmetic flaws which all vehicles typically have, but not something like this.

Sounds very plausible.
A weak 12v battery can cause all sorts of problems. Good thing is they all get fixed once a new battery is installed.

They can get all that info from PTS.

There certainly is the possibility that you may have a LVB bad from stock. Ive had 12v batteries fail with as little as 5K miles. From my understanding, the LVB provides power to everything, including starting, shifting, etc. The HVB only gives power to the motors and to recharge the LVB. I dont see how a bad HVB would prevent you from actually starting the truck unless software dictates so. Fingers crossed they replace the LVB and all is good.
