When driving a error message on the front radar randomly appears. It says "unavailable front radar obstruction" and affects the adaptive cruise control. This error is happening even in clear road conditions and for no reason. Other people are reporting same error message for no reason also.

When is in motion on any type of street and also at a stop, when getting close to a vehicle or if someone cuts in front of me, or if there is a street sign directly in front of the car, this message appears very briefly "unavailable front radar obstruction" which also shows the icon of two front end of cars colliding. This happened immediately after puchasing my 2018 Maxima. The dealership has not said a word about being aware of this problem when it is a known problem with certain Nissan vehicles. The cost to bring it into the dealership and for any repairs at this point would be out of my pocket since the car is no longer under warranty. This faulty radar compromises the emergency braking system in the car.

Unavailable front radar obstruction. This alert happens at random times when driving, it puts the sensor in an unavailable mode which in turns does not allow the safety function to work properly. I have done searches online and this is happening not only to Maximas but to other Nissan make/models. This is not a one time and done occurrence it happens often. When we purchased the car safety was one of our biggest concerns leading us to believe Nissan provided safe cars, apparently, that is not the case. In my opinion, this should be a recall fix, this is a safety issue!
