False forward collision warnings by model year
What owners say
The forward radar will randomly stop working while driving. When this happens it will be out anywhere from a few seconds to up to 10 minutes so far. This failure causes the cruise control to stop working as well as the collision warning, emergency braking, and pedestrian safety to fail to operate.
I bought this from a nissan dealer november 2018. A month after purchase a warning appeared on the dash stating "unavailable front radar obstruction" followed by the deactivated radar symbol that remains on the dash. I called the dealer to see if any recalls we're out for the collision warning sensor. They said no. I know that the nissan muranos have also had issues with this sensor. It started going off about once a day, now it deactivates nearly six or more times a day and I driving me crazy. When I looked into this issue with the murano, they mentioned that occasionally the "auto brake" feature would engage while driving after seeing this message and I am afraid my vehicle will do the same.
Tl* the contact owns a 2018 nissan sentra.

Collision avoidance failed and accerator appeared to stick resulting in accident.in motion approaching lovers lane on noble avenue when driver passed out resulting in multiple rearend stationary object and side collision.
Automatic emergency braking system sensor frequently lights up with a warning radar unavailable while driving on the highway and local streets. I just got this car and after one day I had to take it back to the dealer. First they said they would replace the sensor. After four days in the shop they said they cleaned the sensor and cleared the codes. They also calibrated the sensor. The next day it happened again twice. I have an appointment to take it back to the dealer in two days. In reading the federal safety agency website there are many reports of this problem with this year and model car, with the forward collision avoidance system. Many owners have reported this issue. Nissan has failed to issue a recall or fix the problem. These cars are lemons. The failure can cause an accident or something a lot more serious. Action needs to be taken.
