Truck Completely Dies after Shifting into Reverse

[dmac]

I've had 2 occurences of this issue in the past month:
- when I shift the truck into reverse after a 5-10 minute drive, the entire truck, screens and steering will all completely shut off, sometimes while moving at a slow speed

Many occurences of:
- Adaptive cruise unavailable - steering assist fault (comes on briefly while driving, then goes away)

1 occurence of:
- Shift D to R and back to D while parking, and begin to intermittently lose EPAS (causing a vibrating shaking) as shown in my attached video.

I have seen the following codes:
- PSCM U3003
- PSCM U3003: 16
- ATCM B11D9: 16
- ABS U3001:68

My battery is 20 month old Everstart Platinum AGM H8, shows 90% and 12.5+ volts.



I don't think it's the battery when I am the only one who has reported this issue with lots of people having bad batteries out here.

Any feedback would be appreciated, as it's almost impossible to predict when it will happen and the dealer just looks at me like I'm crazy.

TY in advance

Don’t know if this is tied to the same issue or not. Just happens for the first time my truck also shut off at low speed. Wasn’t after shifting into reverse. I was 1/4 mile from our parking garage slowly pulling up to a stop sign. Felt the truck apply full brakes. Hit the gas and it did it again and shifted itself into park! Had to restart and then just rolled the dice going home. My truck shakes like crazy while cold. Wonder if this is tied to the fuel pump issues?
