Brake Sensor problems of the 2017 Nissan Murano

The forward emergency braking is getting false triggers and disables itself after such incident. Many times triggers without anything in front of vehicle. Has also applied brakes on one occasion when there was no vehicle or pedestrian in front of vehicle. The Feb sensor was updated in 2019 with a new part that does not send false triggers. This is a common problem with Muranos from 2015-2018. This safety feature is one of the reasons we bought this car and now that feature is not reliable. I think Nissan should supply updated part and let customer pay labor to have this safety feature be more reliable.

My automatic braking system and cruise control disables itself. Component from bosch. The flaw in the radar unit allows the sensor to frequently deactivate itself, disabling cruise control and emergency braking. When the sensor turns itself off, drivers are seeing a warning in the dash that says, �front radar unavailable due to obstruction. � this happens multiple times in a given day.

While driving about 15 - 20 mph on a city street, the automatic emergency braking system activated for no apparent reason. There was a 3 beep warning then the car stopped abruptly. The dealer, central avenue Nissan in yonkers, NY. Checked the system and received code c1b55 (elsewhere in the report cited, c1355), radar blockage, (stored past code). The technician attributed this to "side radar blockage" they checked the area of the sensor and found no debris. Nissan service was not clear why a false side radar blockage warning should trigger abrupt braking. Also, they didn't actually fix any problem. The report is available if requested and contains supplementary information from the service diagnostics not generally shown to the customer.

My car has a front emergency braking system. The sensor for this system is located at the front of the car, underneath one of the head lights. The sensor detects when a vehicle in front of you has stopped. As you get closer to the vehicle, if you do not stop, the car will sound a 3-beep alert notifying you to stop. If you still do not stop, the car will apply the brakes and force the car to stop to prevent an accident. One night, I was driving home on a city street, when the 3-beep alert sounded, and the dashboard display started flashing red and white lights. There was a message on the display stating that a crash was imminent. Then the brakes engaged suddenly, and the car almost came to a complete stop in the middle of the street. The brakes engaged so hard and so quickly, that it threw me forward in the seat. At the time, there was no car in front of me coming to a sudden stop and no crash was imminent. The closest car to me was 2-3 car lengths ahead, and it had not stopped. Thankfully, the street was not busy at the time, and there was no accident. Nissan is aware of this issue, and there are class action lawsuits, but Nissan won't issue a recall. I've taken my car to 2 Nissan dealerships and they won't replace the sensor. The first dealer told me my sensor was dirty, but that doesn't explain what happened. According to the owner's manual, if the sensor is dirty, there will be a message on the dashboard display indicating the sensor is obstructed, and the front braking system will turn off. That is not what happened to me. The second Nissan dealer did a software update on my car and reset the sensor. I keep being told to bring the car back if the issue happens again, but this is not the kind of issue you want to wait to have happen again. What if I am on a busy street or the highway? I could have a serious accident. Please investigate this.

The dealer told me my sensor bracket was slightly bent, but the vehile was bought new and never in an accedent I asked if the braket was installed form the factory slightly bent they said it could of been? this doesn't explain what happened. According to the owner's manual, if the sensor bracket was bent it should never of worked from the start??? , if this were the case, there will be a message on the dashboard display indicating the sensor is obstructed or not funtioning, and the front braking system will turn off. This was the 3rd time it has happened . I decided to get another unbiased opinion from a non Nissan dealer repair shop. They ordered a bracket from Nissan and showed me that it was not bent that Nissan has an issue with the crash sensor and is looking for any way to deny the repair. The shop owner told me to call nssan and have a rep comeout.
