Owner reports
Selected complaints filed with NHTSA by 2018 Nissan Murano owners, lightly cleaned up (personal details are redacted by NHTSA).
While driving with cruise control set at 80, I passed a vehicle and as I began to return to the driving lane from the passing lane, the control panel beeped and a warning "front radar unavailable due to obstruction" appeared and the vehicle immediately decelerated drastically and the cruise control was disengaged and disabled. I had to react quickly to avoid a rear collision by accelerating rapidly. There were no vehicles in front of me or on either side. The cruise was disabled for about 4-5 minutes. This happened a total of 12 times in a 5. 5 hour trip. I googled the problem and realized that it was ongoing for many years and involved a recall on other vehicles, but not mine.This is dangerous and should be a recall part before someone gets killed or seriously injured.
I have a 2018 Nissan Murano platinum AWD. I will be driving on cruise control and it will turn off and the collision light lights up and car will come to a stop. The warning system gives a clue as to what is going on, it says radar obstruction. This happens at any speed, at random, with or without cruise control and has been happening many times a day for months, sometimes with the car behind me almost hitting my car because of the fault of the system. I took it to hgreg delray Nissan and they basically blew me off as if it wasn't an issue. The service manager actually told me to drive it and when the light comes on bring it back to him. They didn't even do a test drive! Well, I left that dealer since they are unwilling to help out with what I think is a severe motor vehicle safety issue. I will continue my quest to get this fixed at another Nissan dealer. …
The abe warning light (orange) displays and the warning message 'unavailable front radar obstruction' appears randomly. This happens sporadically and intermittently while driving under various conditions (highway, street, turning, lane changes, straight ahead in one lane, seems to be at speeds of 40 MPH and above and occurs with cruise control activated or not activated ). After pulling over, stopping and turning the vehicle off, the warning light does go off. The abe warning light also will go off on its own within a few minutes without having stopped the vehicle. In any case, upon inspection of the area of the front bumper where the sensor is located, there is no obstruction (no dirt or other substance or object). Note: if this warning scenario occurs while the cruise control is activated, the cruise control is instantly inactivated and the car begins to slow immediately. …

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.
Tl* the contact owns a 2018 Nissan Murano. While driving various speeds, the cruise control disengaged without warning. The contact stated that the cruise control feature of the vehicle was controlled by a collision control system, which malfunctioned while on an incline and while driving various speeds on a bridge. Each time the failure occurred, the vehicle decelerated without any warning or brake lights illuminated. The dealer was not made aware of the failure. The manufacturer was made aware of the failure and provided the contact with case number: 32755178. The failure mileage was approximately 500.
I just purchased a 2018 Nissan Murano platinum "as is" with no warranty. After driving I am now noticing a beep and message across dash that says "unavailable front radar obstructed." cruise control is not even on. I researched the problem and found it is a very widespread problem with several Nissan models. I am so frustrated now. I am afraid to use cruise control which I like to use from time to time when traveling. If there is a fix I don't feel that I should have to pay for it. This is a problem Nissan has known about due to a defective part. Not sure where to go from here or what to do.
Tl* the contact owns a 2018 Nissan Murano. While driving with the cruise control activated, a warning indicator illuminated on the speedometer. Suddenly, the cruise control became inoperable. The vehicle was taken to tom naquin Chevrolet Nissan Cadillac (2500 w lexington ave, elkhart, in 46514) where they stated that they were aware of the failure; however, Nissan had not issued a recall. The vehicle was taken back and forth to the dealer several times. The manufacturer was notified, but did not assist. The vehicle was not diagnosed or repaired. The failure mileage was 14.
June 7 2019 Murano platinum 21,470 miles driving @various speeds, in any weather, a warning light comes on that reads "front radar unavailable due to obstruction". I have checked the sensor and nothing is obstructing it. It will stay on for a few minutes and then shut off, only to come on again. When this happens, the cruise control shuts off without warning creating a hazardous situation in traffic with sudden deceleration. This warning comes on multiple times during any normal driving on street, highways, byways, or standing still. - inverness, fl, USA
On any roadway (city street highway interstate in motion) warning light displays unavailable front radar obstruction while cruise control is on. Then cuts cruise control off and slows vehicle down. Warning continues intermittently while driving with cruise control off or on. Cruise control will not work with warning on. If vehicle is turned off and restarted light turns off only to return again. Seems to be when driving 40 MPH or above that this happens. Checked vehicle and there is no obstruction.
