The car will not start using push to start with the brake pedal depressed. The car is an automatic and the problem is due to a faulty stop light switch. The safety concern is that the brake lights are not functioning correctly and is a safety concern. This seems to be a common problem and the car is less than 2 years old.

The front radar is faulty and is causing issues with the front emergency braking (feb). There is a notification that says "feb unavailable: front radar obstruction". This is causing a regular distraction to the driver and also poses in a risk that the vehicle may automatically brake unexpectedly or not brake in an emergency situation.

A warning in the dash that says, 'front radar unavailable due to obstruction.' the vehicle does this while in motion. The vehicle has 52190 miles on it at this time. The warning will reset when turning off the car and restarting. There are no items obstructed. Nissan dealership stated very common and replacing a lot of them. $1200 is the cost of repair quoted and the service advisor knew that without looking it up.…

Front radar obstruction goes off. Recently it caused problems with my abs to not work and disengage at times. Could be driving on an empty road and it will go off.

While driving on the highway, during the morning, my car activated the brakes on its own, this is the second time this happens the first time i took it to the dealer and asked for the sensors to be removed, and kept it for a whole day and apparently nothing was done, secondly the (front radar obstruction) is becoming annoying. Another of the issues i encountered with this my altima is the shifting, from 2nd to 3rd…

It said that the radar was unavailable because of an obstruction. It happened again at an intersection. It seems to go off several times a day when it senses cars beside me, at intersections, turning... I made an appointment with nissan service at jeff wyler kong?s nissan in…

Another problem im having is a knocking sound under driver feet while driving and turning i took it in to have it checked and the technician drove it heard the sound kept the car a whole day but said he couldn't find anything wrong but clearly there is a…

While driving the vehicle, notification of "feb: unavailable front radar obstruction" comes on and stays illuminated for upwards of 5 to 10 minutes before turning off. This occurs when there are no vehicles in front of mine and no road hazards that would have triggered it to turn on. I feel that this is a big safety issue with the way the car is designed to stop when it detects a hazard. This started out randomly…

The front electronic braking system feb intermittently goes out saying "front radar obstruction" every time i drive the car. If the car is turned off then back on it works normally but will happen again within an hour or so every time it's driven, no exceptions.

The forward collision warning component becomes 'unavailable' when there is nothing (no dirt or rain, snow) blocking the sensor. I keep the sensor wiped clean and on a nice sunny day, while vehicle is in motion on the highway, boulevard, residential streets. The sensor warning will tell me 'fcw unavailable' with the 'symbol' of two cars crashing. It goes on for a while then off then back on again. In the photo…

The car will not start if the break is somehow "stuck". You have to pump on the breaks to release it for the car to start. If the car does start, the breaks may be stuck when i come to a complete stop at which time the car can't drive faster than 5 mph and sometimes the car just stays in one spot. I have two other nissan cars and i have experienced the same problem. I truly believe that nissan has issues with the…

My 2018 nissan altima randomly throws out a message to the dash saying, "front radar unavailable due to obstruction" and this is accompanied by a warning beep, which causes a moment of panic. This occurs even on an open road with no other cars or obstructions present. This is an obvious safety concern since the braking system is disabled when this occurs. We went to the local dealer and they want $165 to diagnose…

The first time i was traveling about 75…

I bought my 2018 nissan altima sr midnight edition around october 2018. When i reached about 8,500 miles the cars front radar sensor went off, and my altima would say front radar unavailable due to obstruction, and this would go on and off the whole week. I called the dealer and they told me to come and we'll take a look at it. That week i went to the dealership and they told me that it's cover by warranty and that…

The aeb (automatic emergency braking) system malfunctions continuously. I get a warning (front senors unavailable due to obstruction) but there is no obstruction. This shuts off the safety system that was designed to sense and stop the vehicle in an emergency. Many, many other nissan owners are having this same issue and nissan is failing to do a recall and fix it. Just as the system alerted me while driving…

I drive a black 2018 nissan altima sr special edition. My car currently has 24,000 miles on it. As i was driving down the street my automatic braking system was activated and my car slowed down and tried to stop on its own. I understand that the purpose of the abs is to assist drivers in safely stopping the vehicle when they are to close to an object and/or another car in front of them. However there was no car in…

While driving during rain conditions, the forward radar repeatedly disables itself with an "obstruction" warning, which also disables the automatic emergency braking function. This issue does not present during dry weather conditions, and does not happen while transiting through a car wash. This problem was first noted in october 2018 when driving in rainy weather for the first time. The vehicle was new, with 00004…

The front radar aeb keeps going out, almost the reason for my vehicle to not stop in an emergency situation. This feature was the complete reason i bought it now i feel like it is dangerous. I am considering asking for complete buy out of my loan. I have taken the car back 3 times in 3, nissan has no answers other than keep replacing faulty sensor with more faulty sensor.

I was driving at 45 mph on a city street. The automatic braking system engaged when a gust of wind blew leaves in front of my car. Fortunately no cars were close behind me because it was as if i slammed on the brakes. Being triggered by leaves seems too sensitive.
