2020 Chevrolet Equinox cruise control problems

I was pulling up to a family member's car port, behind their car. The car port has a grass portion leading up to the gravel section where they park their car. I pulled in slowly when my 2020 equinox suddenly accelerated! I was on the brake, but the vehicle kept accelerating causing it to run into the back of the family member's car. My vehicle continued to accelerate shoving the car forward sandwiching it between my vehicle and their home.I was able to put it in neutral as the engine continued revving up the rpms.

Adaptive cruise control when on closest setting will not stop the car when you are going over 60MPH, when a car drastically slows down in front of you the car fails to respond in fact the adaptive cruise control shuts off and ive practically hit the vehicle in front of me many times ..its hard to trust this system..and the other day it just shut off all together without a hard warning I could have plowed into the car in front of me. Also the lane assist does not beep/or seat rattle when you veer from your lane.
