general problems of the 2018 Nissan Murano

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.

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.

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.

Intelligent forward collision warning system randomly shuts off.

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.

"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.

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.

Obstacle radar failure (front) - vehicle in motion ; "city street" " driving straight " dash warning ; front collision radar obstructed. No obstruction noted by dot certified inspector . Inspector witnessed warning on dash while vehicle in motion - warning occurred approximately every 10 minutes while in motion on city streets . . . Warning occurred regardless to whether there was surrounding traffic in the vicinity .

Forward collision system turns off on a regular basis as you are driving.

Radar sensor issue started about 6 weeks, started getting message front radar unavailable, it wound show for a few seconds then go away, in the last two weeks it has increased to 2-3 times a day ( I was driving 5-10 miles daily) yesterday we drove about 40 miles and it happened at least 6 times. I called Nissan where I had made my purchase in March 2018 and the lady advised there had been several of these situations happening. We have a service appointment on oct 2 2018.
