2017 GMC ACADIA Forward Collision Avoidance Warnings Problems

As i am driving it flashes the warning sign like if I was going to hit another vehicle when there is no car in front of me, this has happened since I purchase the care 1/2024, this has happen around l7 to 8 times already.

Transmission shutters, shakes and jumps while accelerating. Forward collision warning will come on at any point even if there is no vehicles in front of me. I have contacted GMC but was told that it’s a normal transmission issue

I bought my vehicle in 2020. In 2019, there was a special coverage notice (N172097060) with part repair because of known service side detection issues for water module intrusion. My understanding is this is due to the poor design and placement of the item in the rear of the vehicle that is known for getting water in it when driving, which then impacts the entire electronic system (not just service side detection). Beginning in spring 2023, I began to have these issues, starting with service side detection first. I then had other major electrical issues connected to this issue I believe are a safety concern. I have had very scary episodes at high speeds of my entire car electronic system shutting down, speedometer going to zero, gas going to empty, glitching and not starting multiple times. It got to the point my entire car was not drivable due to this...
