The sensor shuts off and warning beeps -??Unavailable Front Radar Obstruction-?? which then shuts off cruise control and crash avoidance. This happens in dry weather with no rain or snow.

- Lansing, MI, USA

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. I have heard of a few people with the same issue having some success when the dealer has replaced the radar sensor.

I took it to a dealer where they indicated a faulty icc module that I am having to replace at a cost of over $1000. (it is being fixed today so I do not have the invoice yet.) this is dangerous and should be a recall part before someone gets killed or seriously injured.

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.

While driving my 2018 Nissan Murano, all of a sudden my vehicle began to de-accelerate and lost it's ability to accelerate. I immediately attempted to pull onto the median of the highway and realized that my brakes were malfunctunctioning, but by then my vehicle was at such a low speed that the brakes were able to stop my vehicle when the peddle was depressed all the way to the floorboard. Three warning lights were indicated on my warning screen and my RPM indicator was bouncing up and down. I called my dealership (my vechicle, was still under factory warranty) and they directed me to a number to call for towing services. In the meantime, I cranked my car several times, and each time the same warning lights were on, the RPM indicator continued to bounce, and the vehicle's engine was geared up while the vehicle was shaking. After my vehicle was taken to the dealerhip (petro Nissan in hattiesburg, ms) they told me that the only way they could diagnose and repair the malfunction was to "replicate the malfunction in my vehicle". after three days, the dealership said that the malfunction was not replicated so there was nothing the dealership could to repair the malfunction. The dealership also refused to furnish me with a loaner car because the malfunction wasn't diagnosed. So, I am now in a situation where my car remains unsafe to operate, but I cannot in good conscience sell or trade it in and allow someone to operate this dangerous vehicle. I am in a very precarious situation but cannot afford to simply sideline this vehicle and purchase another. Nissan is forcing me to operate a vehicle which is a danger to the occupants of this vehicle and to those others on the streets and highways.

Purchased 2018 Nissan morano sl SUV on 12/14/2019. Driving from dealer on 4 lane highway, approx. 3 mi., dashboard displayed 'unavailable front radar obstruction'. it has randomly displayed this ever since. Nissan dealer stated they have been 'desensitizing' the radar as a remedy but denied having any previous knowledge of this defect.

- Kewaskum, WI, USA

"unavailable front radar obstructed" errors appear on dash about every 10-15 minutes while driving. If the cruise is on, it disables the cruise setting and the car immediately slows down. Emergency braking is also disabled when this error happens. If a car is following while driving at 70mph and the cruise disengages this could cause a rear end collision to happen.

- Parker, CO, USA

Unavailable front radar obstruction error intermittently. Cruise control is disabled.

- Ellenwood, GA, USA

Warning comes on "unavailable front radar", happens no matter what the outside conditions. Disables the cruise control. Sometimes I can recycle and the cruise will start to work again and sometimes I have to wait several minutes to be able to reactivate. Automatic braking is also disabled during this time. Happens at any speed.

- Bloomington, MN, USA

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.

Intelligent cruise control front radar sensor continuously alarming for obstruction which renders the cruise control unusable and does not provide any front crash protection. This occurs anytime I am following a car and move to pass a car, the system will alarm for obstruction which can take up to 1/2 hour before it resets.

- Belpre, OH, 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.

- Lacombe, LA, USA

When entering certain intersections, there is almost 100% probability that I get the following message: 'unavailable front radar obstruction'. it's happening every day on the same spots and the number of these spots is growing. This causes the radar to be not working for about 3 minutes. It's been happening for about a year or so. The last time just less then 2 hours ago.

While driving, a safety light keeps coming 'unavailable front radar obstruction'. this happens even without anything blocking the radar. This also controls the cruise control and if not working cc gets disabled. It also controls emergency braking.

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
