Equinox ACC going crazy

[SirAndrew]

Has anyone else’s ACC gone wild by speeding up to chase a motorcycle splitting lanes, only to slam on the brakes once it passes the car ahead? And what's up with all the phantom braking in this spot with no shoulder between the HOV lane and K Rail? It's a total mess! Is my car busted, or is this just a weird issue?

Your ACC isn’t busted, but it’s struggling with object detection in complex traffic. Motorcycles + K Rails confuse radar and camera fusion sometimes. A calibration or update might smooth things out.
