Brake Sensor problems of the 2018 Nissan Murano

I was driving for the first time in this vehicle on interstate with cruise control activated and the car sensor speed control set to the lowest setting. I changed lanes to pass a car, and after passing, signaled to return back to the lane. The car suddenly beeped and a warning appeared "front radar unavailable due to obstruction" and the car suddenly deactivated the cruise control and braked. There were no vehicles in front or beside me. I floored the accelerator so that the car behind me didn't hit me. It happened several more times, so I turned off the cruise control until I could safely stop and check the manual to see what happened. I googled the warning and immediately saw that this was a common problem. On my return home it happened at least 8 times with no warning in a 3 hour trip. The cruise control remains deactivated for a period of time before you can engage it again.

Car brakes hard all the sudden, almost cause me a accident, I clean the sensor thinking it qas dirt is doing the same thing. Also when that happens the center screen goes off I lose the radio. I have to turn off the car and on again.

Cruise control is inoperable and automatic emergency braking system (aeb) is deactivated. Warning comes on stating �front radar unavailable due to obstruction. � Nissan service department indicated on warranty service invoice that problem is related to sensor unit and noted "replace adas".
