NISSAN 2018 SENTRA AUTOMATIC EMERGENCY BRAKING (AEB), RELIES ON A RADAR IN THE FRONT GRILLE TO MONITOR A CAR'S PROXIMITY TO THE VEHICLE AHEAD, WARN OF POSSIBLE COLLISIONS, AND HIT THE BRAKES IF THE DRIVER CAN'T. BUT A PROBLEM WITH SOME OF THOSE RADAR MODULES ' A THIRD-PARTY COMPONENT SUPPLIED BY BOSCH ' MAKES THE SENSOR FREQUENTLY DEACTIVATE ITSELF, DISABLING CRUISE CONTROL AND THE EMERGENCY BRAKING SYSTEM. A WARNING FLASHES ON THE DASHBOARD TO INDICATE THE PROBLEM: 'FRONT RADAR UNAVAILABLE DUE TO OBSTRUCTION.'
FRONT RADAR UNAVAILABLE DUE TO OBSTRUCTION FLASHED ON THE DASHBOARD WHILE IN MOTION.
WHEN BRAKING, IF YOU ARE NOT CAREFUL YOUR FOOT MAY BE ON BOTH THE BRAKE AND THE GAS AT THE SAME TIME, MAKING CAR TO EXCELERATE. GAS AND BRAKE PEDAL ARE VERY CLOSE TO EACH OTHER. WHEN YOU ARE DRIVING AND GO TO BRAKE IS WHEN IT HAPPENS, ANYWHERE.
MALFUNCTIONING ICC RADAR SENSOR MALFUNCTIONING. I'M RECEIVING A WARNING MESSAGE "FRONT RADAR OBSTRUCTION". DEALER REFUSES TO FIX BECAUSE MY MILEAGE IS TOO HIGH

19V654000 · Back Over Prevention: Sensing System: Camera
Sep 12, 2019
Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Consequence & remedy
Consequence: The lack of an image in the back-up camera display increases the risk of a crash.
Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
