Driving on freeway less than 35 mph, car made loud noise for 1-2 minutes at same time i felt under floor board something pulling. i tried to slow down, brakes didn't work. i rear ended a car. the car gear shift popped into reverse; i pressed harder on brakes & they finally worked. i noticed a big light on the dashboard saying 'malfunction, check owners manual' there was a gray symbol near these words. inside the speedometer circle that same symbol appeared in bright yellow. at some point within an hour 2 more yellow symbols appeared on the far left of the dash, a yellow triangle with an explanation point, and a car with 2 curved lines behind the back tires. when the car was returned to the dealership i purchased it from, the staff immediately attempted to blame me for the incident'asking why didn't i bring the car in for service? and that i have to get a rental car and my car repair through my insurance company. he pushed the idea of getting the car repaired. i stated i just barely got the car 3-4 weeks ago brand new. i left the car to be checked by service department. the next day the service manager denied any malfunction saying there wasn't any current codes just past codes; i asked what that meant he said a brake sensor and some other data i didn't comprehend. he said get my insurance to fix the car. i said no sir, i want more information on why the car malfunction first. once i explain to him again what happened he said he would have his forman check out this car the next morning; however less than an hour the service manager me back to say he talked to a field tech engineer and was advised that i had a right to call nissan corp to make a report. i went by srvc dpt to get something, they tried to get to take/repair my car. i didn't. once i spoke to nissan corp they said it take 6-8 weeks for investigation etc to be completed and for me not to get car repaired.
The front bumper sensor is detecting things in the road that aren't there and automatically applying the brakes on my car. when this happens, there's a loud almost grinding sound and the car brakes very hard. the other issue i'm having is the car will sometimes detect someone in the passenger seat when it's empty and turn on the buckle seat belt light and turn off the air bag off light for the passenger seat.
Front radar sensor is faulty. causing emergency braking feature to become disabled.
Faulty radar on front of my car caused speed control and emergency braking system to malfunction while in motion. this occurred sporadically since new and then constantly for last 3 months. i finally took the car in for troubleshooting last week and the radar unit on the front of the car was replaced. this fixed the problem but it should be brought to someones attention because of the safety hazards involved.
I purchase 2019 nissan sentra on 11/6/2019 with 15 miles at nissan of muskogee. since purchase the automatic emergency braking (aeb) system deactivates and shows a warning on the dashboard 'front radar unavailable due to obstruction.' a crash icon also on dashboard at all times. no cruise control. the car is out of balance. the sensor comes on at all time wether or not there are other vehicle near the car. the dealership and service department alleges that i am the only one with this problem and the parts not available. i brought it in to service. the dealership service barely look at the car nor check codes. the balance is worse. this is cause by a faulty defective radar sensor in the front grill. service is now waiting for parts that nissan can't get anywhere.
