2018 Nissan Altima UNKNOWN OR OTHER

I PURCHASED A USED 2018 ALTIMA YESTERDAY. DURING THE TEST DRIVE AND DURING MY COMMUTE THIS MORNING, I RECEIVED AN ERROR MESSAGE "RADAR UNAVAILABLE FRONT OBSTRUCTION". UPON RESEARCH, THIS IS A PROBLEM KNOWN TO NISSAN WITH THE BOSCH SENSOR MOUNTED IN THE FRONT GRILL.

WHILE DRIVING VEHICLE A NOTIFICATION OF 'FEB: UNAVAILABLE FRONT RADAR OBSTRUCTION' IS CONSTANTLY COMING ON LCD SCREEN ON DASHBOARD WHILE A CHECK LIGHT OF 2 VEHICLES IN HEAD ON COLLISION CONSTANTLY SHOWS UP AND LEAVES THE DASHBOARD.

ON ONE OCCASSION THE RADIO SYSTEM FROZE AND THE BACK UP CAMERA WASN'T WORKING BECAUSE THE SCREEN WENT BLACK. VOLUME ALSO COULD NOT BE TURNED DOWN

2018 NISSAN ALTIMA - FRONT RADAR UNAVAILABLE. THIS VEHICLE WILL HAVE THE INTELLIGENT BRAKE ASSIST UNEXPECTEDLY BE DISENGAGED. A WARNING LIGHT AND SOUND WILL BE ACTIVATED INDICATING THAT THE THE BRAKE ASSIST HAS BEEN RENDERED USELESS AS WELL AS THE CRUISE CONTROL FUNCTION. THIS IS AN EVERY DRIVE OCCURRENCE.

FRONT CRASH CAMERA. IT GOES OFF FOR NO REASON. IF I'M DRIVING ON THE FREEWAY & IT JUST GOES OFF, IF I'M GOING ON A FLYOVER RAMP IT PICKS UP THE CTB (CONCRETE TRAFFIC BARRIER) & GOES OFF AGAIN. IT DON'T MATTER WHERE OR WHAT IT JUST GOES OFF.

VEHICLE IN MOTION, THE FLAW IS IN THE FRONT RADAR/DISTANCE SENSOR UNIT ALLOWS THE SENSOR TO FREQUENTLY DEACTIVATE ITSELF, DISABLING CRUISE CONTROL AND EMERGENCY BRAKING. WHEN THE SENSOR TURN ITSELF OFF, DRIVERS ARE SEEING A WARNING IN THE DASH THAT SAYS, 'FRONT RADAR UNAVAILABLE DUE TO OBSTRUCTION.'

THE 2018 NISSAN ALTIMA SV HAS THE ERROR "UNAVAILABLE: FRONT RADAR OBSTRUCTION." AFTER TAKING THE VEHICLE TO A MECHANIC THEY DETERMINE THE PART IS FAULTY AND NO SYSTEM ERRORS ARE PRESENT. (DOCUMENT CAN BE UPLOADED UPON REQUEST)

THE FRONT END OBSTRUCTION LIGHT AND WARNING SOUND COME ON EVERYTIME I DRIVE MY VEHICLE, THEN GO OFF AND COME BACK ON. I CAN BE DRIVING AT ANY SPEED AND WITH NOTHING AROUND ME. SOMETIMES IT CAUSES MY CAR TO SLOW DOWN.

WAS TRAVELING OVER SNOWY MOUNTAIN PASS. MY MILEAGE WAS 65 WITH HEAVY TRAFFIC. THE FORQARD CRASH WARNING SYSTEM FAILED AND SAID UNAVAILABLE THEN REPORTED I HAD BEEN IN A FRONT END COLLISION. WHICH WASNT TRUE AS I WAS STILL TRAVELING THEN THE CAR KEPT AUTOMATICALLY APPLYING BREAKS. THIS COULD OF CAUSED A SEVERE CRASH HAD THE ROADS BEEN ICY AS IT COULD OF PUT ME IN A SPIN CAUSING A SERIOUS CRASH.

THE AUTOMATIC EMERGENCY BRAKING LIGHT ARBITRARILY COMES ON AND STAYS ON. I CAN BE AT A FULL STOP AND THE LIGHT COMES. SEE THE ATTACHED PICTURE. I CAN BE DRIVING AND THE LIGHT COMES AND STAYS ON. FOR THE MOST PART THIS HAPPENS IN JUST ABOUT ANY DRIVING CONDITIONS

SOME UNAUTHORIZED PERSON OPENED THE TRUNK BY A REMOTE DEVIC E. CAR WAS PARKED, ENGINE OFF.
