I see that many after a long 80+ highway stint or after a DCFC session at EA. Dialing it back to more normal highway speeds or letting the pack cool off after a charge sees them disappear for me.
Same here. I get maybe 8-9 grey power bars appearing after DCFC and driving it at a constant speed on the freeway drops it down to 2-3 bars. All this on a 160 mile road trip.

Here's how it looks after 160 miles before DCFC:

And this is what it looks like after:

I would be interested to know if this is related to the contactor issues or just general poor cooling in the system. I think it's the contactors based on what I have heard during an outofspec podcast where Kyle spoke to a Ford engineer.

The best thing that Ford could do is to replace the contactor with a beefier part that would support the far heavier loads than the GTPE would use.

If the HVBJB contactor issue is the reason for the 5-second limit and grey bars, then this new part would remove those limitations and make the GT and GTPE the beasts that they truly could be while satisfying the entire GT/GTPE customer base and reinforcing brand loyalty.
I parked and went into a meeting for about an hour. When I came back out, I noticed a piece of cardboard sticking out of one of the active grille shutters. I removed it and started the car up and had no bars.
You can see in my screenshot that the battery temp is 86* and the outdoor temp is 72*. Is it possible that the computer analyzes the difference in outdoor temp vs battery temp along with battery demand and then limits power if it senses there isn’t enough cooling. 86* wouldn’t be a temp danger zone, but possibly it pulls power even if a safe temp zone if it senses that it’s not getting enough cooling for the current conditions, thus not allowing you to get into a battery overheat condition.

I should be getting my MME early Sept. Then I'll be an expert. Until then I'm just a googled expert.
0-60 is relative. In my Moke I'm a little nervous when I get to 60.

I've watched many reviews of MME on youtube. I'd like someone to do a deep dive on how the MME uses and measures battery power.

If there is an engineering mind with a GTP it would be of interest to know how the battery/power algorithm(s) work.
