Supercruise repeatedly crosses double yellow lines even with on coming traffic. Sometimes with SC active it will make an auto lane change but halfway through it will randomly swerve into either lane, or just simply turn off without warning. It started happening after a software update in may of 2025. We have provided gm and the dealership with video evidence, along with the dealership mechanic replicating the problems. Gm states that SC is operating as intended and that we are not to bring the truck in for service for that issue again. They denied buy back twice now.
