NHTSA Complaint #11564448 — 2023 GMC CANYON

While slowly driving, like when parking or trying to park vehicle in garage, it will randomly surge when almost at complete stop forcing vehicle to lunge forward requiring operator to apply quick additional firm braking. It almost feels like vehicle is creeping in 2nd gear and decides to downshift into 1st gear just before coming to a stop and engine applies slightly more throttle. I have almost hit garage wall and other vehicles in parking lots due to this issue. Again, it is intermittent but is alarming when happens. I have not had vehicle in for repairs yet but concerns dealer will not be able to duplicate. No warning lights on dash for this issue.
