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.

Brake Petal is hard and you have to punch very hard to stop at slow speed as in a parking lot or traffic. It will scare you because the vehicle doesn’t want to stop when moving at slow speed. Unsure if it does it in reverse or not.

I purchased this vehicle a few weeks ago. I was told by the Salesman that everything worked in the car. I test drove it and the lane departure warning was working so I assumed the forward collision would be working. In real life driving, I have nearly run in to numerous cars as the forward collision does not work. In one instance, someone slammed on their breaks, my collision didn't alert me, thankfully I saw it, but I had to swerve off the road to keep from hitting them. In addition, the cooling seats work, but the heated seats do not work on either side of the front seats. Lastly, I have discovered that my Navigation system does not work. I can't get it to change to my current location and the GPS is X'd out. This is what I have so far, but sadly, I feel more things are going to happen with this vehicle. I am working with the dealership on the forward collision and heated seats, but don't know if I will get anywhere with them. They have said they will not fix the Navigation system, which is affected by the CAL (calibration) error message on my screen.

On several occasions the following warnings will pop up. Service Stabilitrack, Tighen Gas cap, Service trailer brake system, Automatic collision prep unvailable, and the check engine light will come on. Then the dashboard lights will flicker on/off, the montior will turn black, the doors will unlock and lock. It has happened when I am going 70 MPH down the freeway. And on several occassions the car engine will turn off/stall as i am either pulling into an intersection, parking spot or coming to a stop. I will take it to the shop and have the check engine code scanned/turned off and it will be fine for a week and then start again

When driving at slow speeds (restaurant drive-thru, stop and go traffic) I often find myself having difficulty pushing the brake pedal, as it is extremely hard to push down the pedal and the car will not come to a stop for 2-3 feet. I feel a strong vibration during this and a low pitched crunching sound, and cannot push the brake down. I am afraid I will have a collision. I did the 2019 recall in which the dealer recalibrated something with the brakes. But it I continuing to have problems, I took it back to the dealership to test the vacuum pump, but they said the "testing was normal" and they were not willing to drive it long enough to replicate the problem I was having, saying that it was worn rotors and brake pads that were causing the issue. I know what the car feels like when the rotors/pads need changing, and I do have slight vibration when braking at high speeds, but never where I have increased brake effort. Only at slow speeds and if I am pressing the brake multiple times.
