2023 Chevrolet Traverse Driver assistance Problems

To make a very long story short, I was having major software issues with my vehicle. I had the car "blackout" lights screens and everything turn off then when it powered on i would have service lights on for my brakes. I also had my reverse camera go out a few times and my lane assistant light on dash say its not working. All to find out i had a faulty rear control module. Upon replacement i learned this EXACT rear control module is the same one used in other GM vehicles noted in several recalls but the part itself has never been directly recalled. So now I have the same exact part in my vehicle again which is bound to fail again at some point. My vehicle is only 3 years old and has done this with children in the car. I let GM know numerous times and they said since the part is replaced its fine. But I know this exact part is not safe. If you look up the model number on the rear control module you will see how many times it is noted in service bulletins and is main contributor to these issues. Please recall the 2023 chevy traverse. I dont want this part just "updated" it needs redesigned.

While practicing parallel parking in the vehicle for about 1 hour, upon leaving the parking lot, there was a message that popped up on the dashboard reading, “SERVICE BRAKE ASSIST”. When driving the vehicle out the parking lot, the brakes were hard when pressing and the vehicle took a while to brake. I found myself braking at a far distance in order to stop the car at the nearest stop light. I turned my emergency lights and drove carefully home, since the engine light came on, which I parked and turned off the car. The next day, I turn on the vehicle and the engine light is still on, I take it to the local Auto Zone for a code, code P0556 is showing BRAKE BOOSTER PRESSURE SENSOR. I then call the dealership, they tow the vehicle and upon arrival they run diagnostics and text me the following message: “ Buckalew Chevrolet: They looked into all of those. They'd have been induced by the parking brake situation, however eveything in the computers have moved to "history" standing which means the vehicle no longer deems it an issue. If a code is not active or current, there is not much I can do with it. It shows us what the computer saw as having an issue, but not what the issue is or how it occured. Without us being able to duplicate it or it actively giving a signal that we can measure, we are kind of stuck without a paddle.” They next say they don’t find anything and they cannot fix it, there I have to go pick up my vehicle. Therefore I do, but the following weekend I go practice parallel parking AGAIN, and the issue happens all over again with the EMERGENCY BRAKE ASSIST turning on by itself, I continue to have braking problems. “STEERING ASSIST IS REDUCED DRIVE WITH CARE” reads on the dashboard, I call the dealership, they say I have to bring the vehicle in when it’s actively having the issue, and I explain that once I turned off the car, the dashboard message disappeared. No response, no resolution. the dealership just brushed it off and said it was nothing.
