Automatic Emergency Braking problems of the 2015 Chevrolet Tahoe

Went to start my vehicle 10min prior to me taking off. Five min into my drive I felt my Tahoe start to lose power stop shifting. Once I was able to pull over to a safe location put the car into park and put the car back into drive and the car will not move.

The truck vibrates violently when truck I accelerate and feel like I'm losing control of the truck. The transmission is said to have issues with the hydraulic system.

1. ) the wire harness between the body control modules are failing. 2. ) when I tow my boat I could loose braking at any time. Display of " service trailer brake system" overrides all other displays on console. Repetitive chiming noise is very distracting and irritating. 3. ) yes, I took it back in soon after I purchased it (a lot of money) and the chevy rep said it probably was something to do with loose wires concerning the towing. I showed them a picture of the the warning display that I took immediately. They supposedly plugged in a diagnostic reader and said that since the code was no longer showing that they were unable to determine what precisely the issue was, but it was safe to drive. 4. ) component was not inspected by anyone. I was told that if it came on and I was in the area; to bring it in so that they can see the display. 5. ) yes there was a warning message that showed up multiple times. 1 or 2 weeks after being purchased on 3/11/22. I feel that the chevy reps know of the issue ( bad wiring harness between 2 of the body control modules) and acted as if the had no clue of the picture of the warning display that I showed them and they were able to tell me it was safe to drive even though they said they didn't know what the issue was. ???? I like chevy vehicles; it would be nice to see chevy stand behind their product. This is the 2nd Tahoe that I've owned, standing behind your work keeps and promotes customers.
