This vehicle is equipped with a "blind spot detector" system. this system fails "occasionally". this creates a safety issue if it fails when i am trying to change lanes. this has happened at least once. this vehicle has been in for service of this issue 4 or 5 times without any repair. the last time it was in, i was told there are other owners that have this problem and "cadillac is working on a fix". this was more than 5 months ago and i have heard nothing about a fix. i would like this issue addressed on a higher level.
