Might have been the cross traffic alert that caused the stop. It has a very large field of view- two car widths on either side of you.I ran into quite a number of bugs today for the first time. when i reversed the car out of the garage today, it made a loud noise with red stop sign and braked suddenly. My wife was standing there and she thought i braked it for some reason. She was not standing right behind the car though. She was towards the right and i was backing out to the left. She did not see anything behind the car that would've caused this and i did not see anything in the back camera.
On the way back home, it started to drizzle here and both side cameras stopped working. i.e, it no longer showed the blind spot for both left and right signals.
Once i got home the surround parking (360°) was unavailable along with the back camera view. once i parked and put it into reverse again, the back camera view showed up but the surround camera was still unavailable.
