Powerboost instant stall while in motion

[Musclez]

What’s up everyone, just got my 23 xlt power boost, last week while in motion at highway speeds the truck alerted.
“Drivetrain malfunction all electric” and literally stalled out.
Just today it did it again though at city speeds. Has anyone had similar issue?
What the heck is this all about?

First I've personally heard of this. 14k miles on my Powerboost and I have not experienced that.

It’s done it twice today on the highway. Thoughts suggestions?

There is a ground acorn nut by the PCM on the firewall I have seen loose that causes this.

Are you now back at the dealer? Why on earth would you touch your brand new truck?

Why wouldn’t I look for a loose ground? Dealer hasn’t called me back

I drove mine home from the dealer, found a little scratch, called them, and drove it back in the morning so they could touch it up. Good lord, if the vehicle stalled twice I'd have made them take it back! I'm not paying +60K for it to stall twice in the first week. F that

You have a good dealer. Since the day I picked mine up I have had a bad vibration/ noise at about 800RPM and my dealers in the area cant get it in for weeks at a time and then they will hang onto it for another couple weeks. The paint defects I pointed out the day I took delivery took a month to get it in to repair. I cant be without my vehicle for that long.

I’m sorry that is your experience. I hope you get better service moving forward. You certainly deserve it.

You have to understand my dealer that I bought the truck from is about an hour away. So if a loose ground is the issue, I have no problem tightening the bolt on the truck. I will run for scan in the morning and check the DTC to see if anything is up.

Take a peek at that ground. We had a bunch at the plant with the same symptoms.
