2017 Nissan Murano: false forward collision warnings

Filed Mar 23, 2021 · Driver assistance · 40,000 miles · IL

At random times while driving the forward collision warning system and cruise control will stop working. On average it happens about every 20 to 25 miles and remains off for 2 to 3 minutes. It does not occur at regular intervals though, this is just the average. It was very difficult to get nissan to replace the sensor while the car was under warranty. They did not want to and finally when they agreed they said the part was on back order due to high demand so I'm not the only customer who has complained about this. The sensor still does not work properly and having the forward collision warning/automatic braking not reliable is a safety issue. Having the cruise control not work is just an annoyance. At nissan's suggestions, I've cleaned the sensor many times and I've ensured that nothing is blocking the sensor. It is simply a faulty, unreliable part and I believe there should be a national recall. This has been happening for over 2 years now. It took many months of complaining and sending them pictures of it not working before they replaced the sensor the first time. That fixed the issue for a few months but now the second sensor on the car has been malfunctioning for over a year. I'm attaching a couple of pictures for example. This issue has happened over a 100 times to me though.

Happens at least once a trip. The front radar, used for collision mitigation/intelligent cruise control, shuts off and reports obstruction for no apparent reason. This renders the safety systems useless.

Intermittent 'front radar obstruction' warning light and immediate disabling of the predictive forward collision warning, forward emergency braking and cruise control systems. This is a safety issue, particularly for the rapid deceleration that can occur in heavy traffic when using cruise control.

C/s forward collision warning keeps periodically coming on with no obstruction in front of vehicle. When warning occurs it shuts of the cursie control. Very dangerous when driving down the highway.

Platinum package. When car is in motion, forward collision warning system malfunction incorrectly identifies a pending collision, indicating that a collision is imminent. Once the warning occurs, both visual on the dash, and audible beep, it will not go away. It continues until the vehicle is turned off. Occurs often. Dealership attempts to repair fail. Parts departments claim replacement parts are not available. This is dangerous to timid drivers in heavy traffic. Although problem exists in light traffic as well.

C/s forward collision warning keeps periodically coming on with no obstruction in front of vehicle. First reported june 2018, replaced failed again, curating under engineering review, at this time when it alarms all time, also curse control does not work, and side alarm off and on. When in motion, we have insurance discount for the collision warning system that is not working.

My vehicle had a warning light come on stating "front collision avoidance unavailable". It would shut off the cruise control. Took it into the dealer. They said the vehicle operated as designed. Took it back in several weeks later demanding they fix the problem. Took a test drive with the technician. Problem did not reoccur. I got out. The technician started the car to pull it in the shop and the warning came on. They traced the problem to a sensor. The sensor is not available and is on backorder. In the mean time the cruise does not operate and the front collision avoidance does not work (waiting 5 weeks now). Cannot depend upon the collision avoidance even though they advertise it.
