2023 Mach E Collision warning system fault

[A horse grl]

Hi everyone, I am hoping that someone out there might be able to help me with an issue that I have recently encountered with my 2023 Mach e. I am driving on the highway and it happens when I am on cruise control or blue cruise. When I am going under a bridge or highway sign my car starts to alarm and slams my brakes on out of the blue. It is incredibly unsafe and scary. I took it in to the dealership and they told me that the new tires that I put on are most likely the cause of this system failure. I am wondering if anyone else out there has heard of this happening. I did change from a 225/55R 19 to a 235/40R 19 and my mechanic said that it was not an issue to change the size of tire. Any suggestions?
