general problems of the 2018 Nissan Altima

I’ve had to replace the break sensor a few times and it’s unusual… my check engine light came on and it reads the code for the catalyst converter. . , the auto part store saw a recall on this for my make and model but not seeing it here . The code was cleared and hasn’t came back on yet but I’m anticipating it will . . These two issues need to be further looked into please.

Brake switch failure contributed to intermitten braking resulting in near crashes.

The problem of delayed acceleration. The problem occurs when the vehicle does not seem to accelerate for a short period of time. When I'm at a stop. And I depresses the pedal. The vehicle does not rev. It does not do anything for a few seconds. Even with increased force on the pedal, the vehicle does not move. The second concern is that, once it does move, it does so significantly with a jolt. This means that, after a few seconds of not functioning, the vehicle will suddenly accelerate quickly. This can create an increased risk of an accident.

Several times while normal driving and nothing in roadway the display will say unauthorized object in view and there's nothing there happens several times a day scares me at first cause I think something wrong and takes 10 minutes for display warning light to turn off.

While driving home and just entering my neighborhood, I noticed a low tire warning on my dashboard. I looked at the pressure and there was approximately 26 pounds still in the tire and the closest place to fill up was at my house. While approaching a right turn in the neighborhood and because of the winter weather conditions of snow and ice on the road, I slowed down to a crawl and applied my brake prior to and while turning. While in the beginning of my turn, I instantly realized that I had no control of my car and I slid into a snow bank on the side of the road. There is no doubt that I was going too slow for my car to slide. I was right down the road from my home so I continued home thinking I could not have had significant damage; however, as I was driving, my ride did not feel normal even though I was traveling at a very slow pace. When I got into my garage, I found my tire was completely flat and the damage was significant to my front driver side bumper. The next morning I removed my tire to see where the puncture was and if it was repairable. Upon further inspection and while filling the tire with air, I realized there was no hole in the tire but there was a fast air leak at the rim. On Monday morning, February 15, 2021 I brought my tire in for repair. I have no doubt that a defect exist in my tire and when I looked to see if there was a recall, I realized that the same tire I have on my vehicle is shown on the recall list but it is for 2019 tires and not 2018. Please look into my complaint and concern. If I had been traveling on a highway, I could have easily been killed. I had no control over my vehicle when the air went out at the rim. My tire is a continental contiprocontact p215/60r16 94t all season dot 6yx8 3yd 2018. The tire says made in slovakia. Other numbers on the tire were 3-979 84579 230385 e4 0231843.

Tl-the contact owns a 2018 Nissan Altima. The contact stated that while driving, the Feb automatic collision notification illuminated then unilluminated. The contact stated that while approached a stop sign at 500 feet, while depressing the brake pedal, it went to the floorboard causing the distance to be extended. As a result, another vehicle came across the contact crashed into the right rear wheel of the other vehicle. No warning lights illuminated. The contact nor the other driver did not sustained injuries. A police report was filed. The other vehicle was towed. The contact was advised by the police office was to use the emergency brake and drove the vehicle to his residence. The vehicle was taken to michael jordan Nissan, 3930 durham-chapel hill blvd, durham, nc 27707, where it was diagnosed but could not find a failure with the brakes but was advised by the dealer that they would keep the vehicle a little longer to investigate. The vehicle was not yet repaired. The manufacturer was made aware of the failure and provided a case number. The failure mileage was approximately 59,000. Aw.

When trying to push start the brakes feel hard and unable to push down so the push start will work. Have to play with the brake pedal in order for it to go down and able to start the car.

Automatic breaking will shut off for about 5 minutes on occasion; especially when turning towards an embankment (I. E. Making a left turn and there's an island there).

I began experiencing issues with what we believe to be my break switch, and while I was driving down the road 3 of my breaks locked up, also taking away my ability to stop.

The front radar obstruction sensor, when the car is in motion, turns off for no apparent reason, at any time or place, highway or local roads. Many times it turns off if I pass a car into an open road. This will affect the aeb system. Nissan dealer has stated that they do not have a fix or a recall for my 2018 Nissan Altima.

The Feb. Forward emergency braking radar keeps disabling with the radar clear.

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.

Intermittent front radar. Warning message will appear stating "front radar unavailble due to obstruction" when there is not an obstruction, then the system deactivates the automatic emergency braking. After a few minutes, the "obstruction" is cleared and the system resumes functionality. This will repeat quite often. While I own a Nissan Altima, it appears this is an issue in the Nissan sentra, as well.

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.

Automatic emergency breaking turns off constantly. When a truck towing a trailer passed me a light came on and a message flashed on the dash. 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 mason ohio. They found dtc # c1a16 radar stain and c1b55-97 radar blockage. They reprogrammed the radar unit. It still didn?t work. They said the part needs to be replaced to the tune of $1637. 86. We bought this car specifically for the aeb. We researched it?s reliability through consumer reports. I checked and there were no recalls. There were no accidents on the vehicle?s history report. I?d run a small general obd reader that did not show the code before buying. We are pretty mad to have extended ourselves to pay more for something that doesn?t work. I?ve called 1800nissan1 so we?ll see if they fix it. So far they?ve only told me it?s not covered, despite how many Nissan models and years are all having the same issue. We couldn?t see it bc they haven?t recalled it.

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.

2018 Nissan Altima has a defective push start and braking system. Unable to start car with push start because it feels as if the brakes are stuck. Have to continously pump the break in a effort to get the brake to release in order to start the car.

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 break system. This is dangerous for people driving on the road with this problem. The dealer is not wanting to fix this problem until their computer generates a code. On my other two cars, the problem got really bad before their system was able to duplicate the problem. People can be stranded if their car doesn't start or get into an accident if the car can't move after a complete stop.

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 problem and $1000 to fix it because we are out of warranty. We purchased the car second hand with 42k miles. They told us that this is a common problem as they see this all the time. We opened a case with Nissan (36978530) and was told they could not help us unless we spent the money to have the problem diagnosed. So, at this point, Nissan is not standing by their product and one of the major reasons we bought the car is not working. And, Nissan knows it!.

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 yesterday, it then quickly shut off saying there was an obstruction. It was not adverse weather conditions and nothing was covering the front of the car. I stopped in time. I have an appointment this week with the Nissan dealer, but with this being a marketed as a safety feature, and included as part of the safety ratings systems by the government, it should be a recall by Nissan. I purchased the car because of the safety system and ratings.

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 front of me when this occurred. It is now happening consistently and I'm afraid to drive it, especially with my two year old son in the car. This could be very dangerous and potentially fatal if it happens at the wrong time!!!.

Radar obstruction warning keeps popping up on screen. Afraid that this would make the car stop and get rear ended. This is happening while driving. .

The contact owns a 2018 Nissan Altima. The contact stated that the vehicle was at a stand still and the ignition failed to start. The contact stated no warning light was illuminated. The vehicle was not drivable. The vehicle was towed to the local dealer fiesta Nissan (5001 s 169c, edinburg, TX 78539, (956) 348-1408) where it was diagnosed with needing an unknown brake switch to be replaced. The vehicle was repaired but experienced the failure three additional times. The manufacturer had been informed of the failure. The failure mileage was approximately 5,000.

After hitting breaks many times and slamming them the car would still not stop.

This is an issue that has been continuously happening since I purchased the vehicle with about 2500 miles on it, it currently has about 6500 miles on it. The emergency braking system continues to turn on and off at various times but has continued to get worse over the few months that I have owned it. The worst situation I have had was recently on a 300 mile round trip when the emergency braking would activate and deactivate every few minutes, in which it would flash on the dash saying the system was obstructed, and the warning light showing it deactivated would turn on, the cruise control would shut off and a keeping sound would turn on. This was happening with no apparent particular incident. The trip took some back roads, a lot of highway (2 lane and 4 lane) and a moderate in city driving. The weather was clear, the sun was out with partial clouding, it was around 40 degrees outside, the roads were dry, some were rough some smooth, other than in the city there was little stop and go traffic. The worst incident was during the return trip, we were on a 2 lane highway that was pretty smooth. There was no one in front of us we were doing approximately 70mph with traffic behind us, we had the cruise control on and were just going along a straight flat stretch of road when the system once again deactivated, beeped then reactivated and beeped and then slammed on the brakes on us. It was only an instant and created no situation of danger based on our position, and as it was instant I was able to step on the gas again and we only dropped from 70 to about 50mph in the period. This was the worst situation I have run into with the issue so I looked it up on the internet and found it is stated as an issue on the sentra. This unexpected deceleration on a freeway could have been a devastating accident.

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 miles on the odometer, at the time of first possession in may 2018. As of 1-10-2019, the odometer reads 14970.

Car would not brake and hit a pole. The vehicle is supposed to have emergency brakes, but did not work. Often would get a message across my dashboard saying it was unavailable.

Purchased Nissan Altima s 2018 , the aeb "automatic emergency breaking " does not function at any time, the computer will not establish a code for it not working either. It's either a faulty computer not establishing a code or the the aeb is faulty. Will not attempt to stop for a pedestrian crossing in the cross walks, will not apply more breaking pressure if I'm not applying enough. Have talked dealership in shelby, nc. Have talked to Nissan corporate , both denie that anything is wrong,simply because the computer will not throw a code. The fact of the matter is "it will not operate" code or no code. This is a safety feature I wanted ,reason for picking the car out. Has people age their reflexes get slower on some individuals, and some people take their eyes off the road to make an adjustment to some other features as mirror adj. Cruise controls etc. Will not give me a car that the fearture works on. Exchanged cars on me after I took a test drive that the feature did work . Demanded it be fixed or first payment will not be made ,to come and get it if Nissan will not fix car or replace car.

Aeb will not apply break when narrowly missing a car that ran a stop sign. The aeb "automatic emergency breaking" does not work at any time, or any situation. Dealership in shelby,nc. Nissan ,refuses to fix not even jad it a month yet. Sincerely, sidney ray tuggle,jr.

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.
