“I was driving and randomly my new 2023 Buick Encore GX and two error messages popped up and my brakes started being less responsive. The two error messages that popped up was Service ESC and Service Power Steering . I will be calling the service department tomorrow to get it checked to make sure nothing is wrong. This is apparently an issue with GM cars but I need to verify that it is not an ongoing issue.”
