The AEB (automatic emergency braking) system gives false positives on a regular basis. Dashboard light comes on, and monitor says there is an obstruction, or AEB not working. Occurs at any speed. Has happened frequently since November 2020 when I purchased vehicle.

I drive a 2018 Nissan Sentra SV The vehicle began having problems with the break/ driving assistance feature. The light is continuously turning on and that feature hardly ever works, making me feel unsafe and at risk of my breaks or something else malfunctioning. To make matters worse, my transmission stopped working, causing me to nearly crash/ get into countless car accidents. This didn’t only add unnecessary stress to my life but made me late to my office job and is now costing me thousands of dollars to fix ! The whole point of buying a new or relatively new car is to avoid these type of issues and this is simply unacceptable! I have spoken to many Nissan owners and more than half (about 8/10) have reported having or know someone who had transmission issues, making me believe this is a huge Nissan issue. My transmission completely gave up on me and I know that this is just not right. I work at a law office that deals with accidents / personal injury and know enough to say this ain’t right. I demand to be compensated for such horrible and faulty vehicle that has cost me time, money, and unnecessary stress.
I purchased this car October 10th of 2021 and 2 days after I purchased it I called my service department because I was driving on the highway at 65 miles an hour and the malfunction warning light came on for the automatic braking system and it also depressed my brakes so it scared the crap out of me.

I purchased this car October 10th of 2021 and 2 days after I purchased it I called my service department because I was driving on the highway at 65 miles an hour and the malfunction warning light came on for the automatic braking system and it also depressed my brakes so it scared the crap out of me. I was told that because of the weather it was raining that day that that sometimes happens. I didn't think anything of it on December 10th my son got into a car accident with the car and he did some damage to the front axle and the front end of the car it has since been repaired and now everyday several times a day the same thing happens and it is messing with my brakes and it's scaring me and I don't know what to do.
The automatic emergency braking system is not working and the dash says “forward collision malfunctioning” with the master warning light on. The car did not brake however the aeb is not functioning.

The contact owns a 2018 Nissan Sentra. The contact stated while driving approximately 60-65 MPH in the rain, the vehicle in front of him splashed water, and the Forward Collision sensors activated the Automatic Emergency Braking (AEB) system, and the vehicle inadvertently stalled while hydroplaning. There were no warning lights illuminated. The dealer was notified of the failure and advised the contact to take the vehicle to the nearest dealer for diagnostic testing. The contact stated he contact a second dealer - West Herr Nissan of Lockport (6069 S. Transit Rd, Lockport, NY 14094) several times to schedule an appointment but no one returned his phone calls. The contact was able to schedule an appointment with the first dealer when he returned to Florida. The contact also stated that the sensing and radar system was malfunctioning, sending faulty messages to the vehicle whenever a bug or water would fall on the vehicle. The manufacturer was notified of the failure and advised the contact that he would be responsible for the cost of the diagnostic test, then they would determine whether they should cover the repair of the vehicle. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 37,000. The consumer stated even if the sensor is maintained and cleaned, it's still malfunctioning. The consumer provided a link showing the defect.
The AEB light came on and message appeared saying "Front Radar Unavailable Due to Obstruction"
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 T…

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.

MY CAR HAS PROBLEM SPEEDING IT FEELS LIKE IT'S LOST IT'S POWER. I SERVICE MY VEHICLE AT THE DEALERS…
