Automatic Emergency Braking problems of the 2020 Nissan Sentra - part 1

The aeb - automatic emergency braking sensors are faulty. The system randomly brakes while I am driving with nothing in the cars path to set it off. It happens frequently and without any seemingly reason. It has become very nerve wracking and potentially dangerous. I brought this issue up to a mechanic at the Nissan repair shop and his response was that the car is no longer under warranty and that I am responsible for what would be a costly repair. He suggested taking the car through the car wash frequently. I constantly wipe the front window where the sensors are located, I find this solution to be unacceptable.

Vehicle had aeb system malfunctioning. The brakes did not work. The emergency brake barely worked. We were driving on fathers day to a family gathering and the system and brakes malfunctioned, yes we collided with the curb and debris on the side of the road cause curb rash to the rims. No major damage. This would be the 3rd this has happened to my vehicle in particular. Dealers say the manufacturer doesn’t cover brake line damage or issue even due to factory fault/ defect.

On June 10 2025 the brake sensor malfunctioned for my 2020 Nissan Sentra this was the secound timethe first time was about one week before. . The brake peddle went down , car brakes ,brakes. I was driving speed limit of 20. There were no cars on the street or object. A yellow triangle appeared on the dash board. . It scared me ,this is a safety hazard that can cause a accident. The next morning my car didn't start. There were a few symbols on the dashboard. . I had it towed to the car dealer. They put a new battery. I just bought it may 04 2025. I was told no sensors were on, mechanic didn't find anything. As of now I have bot picked up my car from the car dealer. 06/24/2025.

Every so often the vehicle’s aeb, fcw, ldw system malfunctions and causes the cel( check engine light ) to come on. The car also looses traction control and begins to sound like the tires are grinding on the pavement. This then puts the motor in a limp mode/ safe mode. During this time the vehicle does not have power and reduces speed to 50mph, the vehicle then revs at 2. 5-5. 5rpm trying to catch/ hold speed. The vehicle begins to shake when this happens. The power windows also don’t work after this happens.

Malfunction brakes from glares on the road (especially in the rain) and now has a malfunction warning.

Aeb system has been malfunctioning when driving applying brakes without warning.

Aeb; forward & rear collision warning indicator light just showed up on Feb 2024. Dashboard message indicating malfunction.

Im filing a complaint iv had more recalls on this car then I ever did on any other brand this is the second recall I had for the tire rod which was already replaced with a new version of the original tire rod then they tell me OH u need a new back up camera and front lights that had recalls as well I do not feel safe driving my car and they sai d there is nothing they can do im furious. When I drive my car the wheel is constantly shaking and thats what the notice said to be weary of. As for the emergency breaking its been happening to often when im going down a road the emergency signal goes off and the breaks engage on my car when there is no other veichles around this should deffinatly be looked into.

When driving my sensors are ringing off as if someone is in front of my car. The brakes will be pushed down stopping the car while driving. Also when driving you hear a loud clicking noise which I was told before its my tired rod. I replaced this tired rod once before when it snapped while driving before this recall was put out. I have complained numerous times to my dealership and they are not taking this matter seriously.

I was traveling on a multi lane road at a speed of approximately 45 mph. There were cars directly behind me. Multiple pedestrian crossings were in front of me but the pedestrians had already crossed the road and were safely on the sidewalk. However, the caution lights from the crosswalk were still illuminated from the pedestrians that had previously crossed. As I reached the pedestrian crossing, the vehicle’s front collision warning system activated and immediately applied heavy brake pressure. There was nothing I could do to override it and since there was nothing in front of my vehicle, the cars behind me were not expecting a sudden stop. The car behind me was able to stop in time but narrowly avoided a collision with the rear of my vehicle as a result.

I purchased this vehicle new (172 miles) from a dealership that also sells used cars. The vehicle was driven from a dealership about 75 miles away from where I purchased the car. I was told the other miles were from test drives. I think the car salesman switched cars after the test-drive, while I was calling my insurance company (can't prove it). I never returned to that dealership. I took my car to a dealership closer to my home for service several times. The automatic braking system, forward collision warning, the adaptive cruise control all malfunction on a regular basis. The service person told me that Nissan couldn't service these issues without the manufacture of the braking systems approval. The dealership gave me paperwork on my first complaint- no repairs were made. The dealership gave me paperwork on my second visit stating intermittent electrical issues- no repairs were made. I did not receive paperwork on my 3rd visit. My 3year/36,000 miles bumper to bumper warranty (that never got used) has expired. I decided to live with these issues because the car runs well- getting a lawyer seems pointless. I took my car to a different dealership (over 45 miles away) because of the steering. I was told that it would cost me $170 for diagnosis. I agreed to the charge. The service person then had me call Nissan to get a work order number ( I found that very odd) why didn't the service person call Nissan? a mechanic looked at the car and told me that I need a new power steering rack and that it isn't covered under warranty. I asked about the recall on the tie rod ends. I was told the tie rod ends have no bearing (ha,ha) on the power steering rack. I was told the power steering rack would cost $2,800 to have installed. The mechanic said he wouldn't drive the car because a wheel might come off while driving. I wasn't charge for my visit and didn't receive any paperwork. My car is parked in my garage with 47,xxx miles on it and is unsafe to drive.

Emergency brake applied for no reason.

The contact owns a 2020 Nissan Sentra. The contact stated that while driving at approximately 20 mph, the self-driving feature inadvertently activated, and the vehicle experienced phantom braking. The traction control warning light was illuminated. Additionally, the key fob was not detected while inside the vehicle. The display screen intermittently went blank while driving. The vehicle was taken to the dealer, where the crash collision sensor and speed limit camera were replaced; however, the failure recurred. The vehicle was then taken to woodhouse Nissan (7801 nebraska dr, bellevue, ne 68005) where the key fob was replaced. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000. The VIN was unavailable.

At 5:44 on hwy 50/elizabeth Ave in pueblo, CO. The automatic emergency braking system locked up with no reason for it to do so. Thankfully we were not rear ended. I have documented via photograph of this system error alert coming on several times a week while driving this vehicle. It has been to the dealership now twice for this issue and will be making yet another appt to get the car back in again.

The automatic emergency braking light would continue to flash on and off, signaling it wasn't working correctly. I took it into the dealership to be repaired and two days after receiving my car back the light came back on. I have done research and have concluded that this is an ongoing and common issue throughout particular Nissan models.

Tie rod end snapped/car will stop out of no where.

I have documented over 2 years of my aeb failing by photograph and video time stamping the continual occurances of this system failing on my vehicle while driving. The vehicle has self engaged the braking in the middle of driving, thankfully I was draveling on a residential road at aprox 30 mph. It was quite scary to experience. I also now have no back up camera, the screen is completely black when vehicle is in reverse, drive as well as park. I have restarted the vehicle hoping it was just a glitch in the system. I feel like this vehicle has been and continuing to be more insane to operate and I have literally only had it for 2 years, brand new off the lot July 2020.

Was driving down the highway nothing in front of me my car hit the brakes and flashed warning on the dash and made me come to a stop after this happened my fuel economy decreased over 100 miles per tank other times it just activates and taps the brakes for no reason also every window except the driver window gets stuck several times a week another thing some how one of my rims cracked.

My car on two occasions came to a stop while driving . Nothing was in front of me at all. A flashing light came on on the dashboard and my car came to a hault. This was very frightening and now I am afraid to drive the car. The dealership said nothing they can do. This issues needs to be addressed and fixed and a recall needs to be done. This is a huge safety issue!!.

Car suddenly stops while driving down the road. There were no obstacles or other vehicles in front of the car.

Today 5/10/2022 was the second time our car is said there was a malfunction with the emergency braking system. We believe we depend on our cars safety features and believe all Nissans should be investigated for possible sensor malfunctions. Thank you.

The electrical system is a nightmare in this vehicle. My automatic emergency braking system was activating while I was going 60mph on the highway with no vehicles or reasons to have this feature activate. It happened on numerous occasions. I had passengers in the car and they witnessed it. It was very alarming to be cruising along at 50+ mph and the braking system jolted the car to a stop. I also had to replace the battery twice. Had to purchase a portable jump starter. Had to replace alternator. None of these things should be an issue with a 36 mo lease I complained numerous times how I felt the car was a death trap. I asked for a loaner if I left car since it’s a safety hazard and I’m sickly and must get to my dr appts. I was told by dealer that’s not their problem. I broke down at night alone at least 5 times. My gas said a quarter tank yet I broke down for no gas. The radio volume knob never worked. The driver rear door never locked. System malfunction wld constantly flash on my screen. The car made a ticking noise inside when shut down. My heater didn’t work. I opened 2 consumer affairs claims. They put me off everyday. The girl tyler did nothing. This car is a death trap. I think the dealer knew it had electrical problems. I kept car past end of lease for legal proof. I continued to pay. Finally I gave up. 5 hrs b4 inspection they sent a tow truck to take vehicle. I lost all belongings in trunk. They were still using my registration and never contacted me or returned calls or sent any letter to get my belongings. They kept new battery and battery jumper. Plz I need help. Nissan has been nasty to me and my [xxx] mom and instead of offering some money back they want to put me in collections for $1500 for mileage. Which I kept paying lease plz help us. Nissan resold vehicle. Someone is going to die in that car information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving my 2020 Nissan Sentra, my car proceeded to brake on its own while I was depressing the accelerator. A red warning light flashed across the dash that looked like 2 cars colliding. I was able to maintain control of the vehicle, even though it was acting erratically. The braking occurred abruptly startling me and the drivers around me. Thankfully, the car did not cause a collision. The incidence scared me immensely causing my heart to palpitate and raising my blood pressure. I looked for the indicator light in my manual after I had come to a complete stop and was able to calm down after the scare. The warning was the automatic emergency braking with pedestrian detection system warning light. The thing was, there were no pedestrians anywhere near my vehicle, nor were there any other vehicles or objects that could've possibly set the system off. It was clear that this system in my car was malfunction. I'm truly scared to drive my car now. I took the car to the dealer to have it looked at and fixed, however, a couple of weeks later, the same incidence occurred. This time I had my child and husband in the car with me they so scared and were immediately tied by the seat belt. They will were able to witness what I had previously experienced. It scared her as well. This malfunction is going to cause unnecessary collisions that will result in harm to someone. This malfunction could easily induce an accident. It is also causing unnecessary wear and tear on vehicle due to the forceful nature of the abrupt braking. My child and I spend a great deal of time in my car, and I cannot take the risk that this car imposes. Please help me!.

I was driving down the highway and my automatic emergency brakes system decided to kick in. Scared the hell out of me. Nobody was hurt thank god! luckily there was no cars around me. Or im sure I could have been seriously hurt or even killed. I took the vehicle to Nissan dealership they kept my car for 3 months and supposedly they fixed the problem. But I have proof of the messages and lights on my dash telling me malfucntion. Like wth?.

The emergency braking system has gone off on this car 4 times. After the first two we took the car into the dealership and they said that they could not find any problems with it. Yesterday we had two more incidents. I am taking the vehicle in tomorrow. I have asked that they replace the sensors but was told that it is up to Nissan. This is a very dangerous thing especially if you are on the freeway and the brakes go on. On incident 2 I was travelling 45-50 mph. Here is information on incidents 3 and 4 this is the 3rd and 4th incident we have had with the neb going off while driving our 2020 Nissan Sentra. Documentation on the first two incidents have already been provided to future Nissan of folsom. The latest incidents occurred on sept 27 2021 at approximately 7 pm. Mileage on the vehicle was 2795 at the time of incident 3. Location was zip code 95608- carmichael CA on both occasions the vehicle was traveling west bound with no traffic in either direction and course driven had no direct sunlight hitting the vehicle. My wife had driven the vehicle approximately 17 miles when the third activation occurred. The maximum speed she had driven the vehicle was 46 mph during the course of the trip. She was on California Ave. And turned right onto van alstine. Her speed was between 20 – 25 mph when she encountered a 15mph speed bump. She lowered her speed to 15 mph and just after she crossed the speed bump the neb went off. I was not jarring but slowed the vehicle down. Approximately 100 feet further a red light went off on the right hand side of the dashboard and there was a beeping but the car did not slow down again. She then stopped at the light on the intersection of van alsine and fair oaks blvd. She proceeded west onto el camino Ave for about 200 yds and reached a speed of approximately 30-35 mph. (speed limit is 40 mph) when the emergency braking system again went off. She does not recall any light going on.

Nissan Sentra 2020 automatic emergency braking system engages for no apparent reason and brings car to complete stop while driving. This has happened about 10 times within the past year. Appears aeb sensors are faulty. Luckily was not rear-ended during incidents. Informed dealership where I bought the car and was told there was nothing they could do to fix the problem unless there is a recall for this issue.

While driving my 2020 Nissan Sentra, my car proceeded to brake on its own while I was depressing the accelerator. A red warning light flashed across the dash that looked like 2 cars colliding.

It was clear that this system in my car was malfunction. I'm truly scared to drive my car now. I took the car to the dealer to have it looked at and fixed, however, a couple of weeks later, the same incidence occurred. This time I had my elderly mother in the car with me. She was able to witness what I had previously experienced. It scared her as well. This malfunction is going to cause unnecessary collisions that will result in harm to someone. This malfunction could easily induce an accident. It is also causing unnecessary wear and tear on vehicle due to the forceful nature of the abrupt braking. I will likely be trading this car in because the dealership cannot seem to remedy the problem. I spend a great deal of time in my car, and I cannot take the risk that this car imposes.

Purchased car in 2020 and within a couple of weeks of purchase I was thrown on brakes warnings flashing that there was an obstruction. This happened in the middle of traffic and I was almost hit. I returned the car and was told because they could not mimic what happened with me there as nothing wrong. Was I sure that paper or something did not fly into the car. I assured them there was nothing. No resolution. . . . Again Friday, 7/9/2021 it happened. I was driving at a slow pace because I was in an unfamiliar area, soon to make a right turn. I was the only car on the street, no type objects in or around the street and suddenly my car brakes and lights are flashing. No objects. Once again Sunday, 7/11/2021. Driving and suddenly braking as before. Nothing in sight that could have caused it to brake. No objects, people, no rain. . . . Nothing to cause a sudden braking once again barely missed being hit. There should be a recall for whatever the issue is with the camera. There were no warnings lamps prior to either incident. Only as it is happening does the warning lamps appear.

Driving 40 mph car for no reason slams on break. Flashing large red warning across the screen. The car is unsafe to drive. Can cause a fatal accident. Passenger and driver at risk for injury due to unaware sudden stop on road while driving. When this happened driver has no control of car. Before the car was purchased I saw a yellow buzzing light. The seller said to leave it over night for repair. The next day I was told by the seller the car was inspected and repaired by manufacturer. The seller said the car was fixed. When I drove it off the lot, the yellow light was still coming on buzzing. Then the car malfunctioned on the road.

I was driving the 60mph speed limit on the highway. The car automatically braked and said an object was on the road. The cruise control was not available due to the error message that popped up. My safety and the safety of my 3 children were at risk because if there were a car behind me, they would have rear ended me, especially going for 60mph to a sudden jerking stop such as that. I was told that some Nissan's distance sensors are malfunctioning this way, but my car is not added to the recall, so I will have to save up to get it corrected. I bought this car brand new last year.

The car has automatically braked on its own with nothing in front of it, it happened on Sunday, may 30th, took the car to dealership on Saturday June 5th, they ran diagnostics and found nothing wrong and on my way home from the dealership the car unprompted braked on its own again. Causing me to stop short in the middle of a road, and again there was nothing in front or near me to cause this. I do not feel safe driving this vehicle.

The contact owns a 2020 Nissan Sentra. The contact stated while driving approximately 45 mph, the full brake assist radar illuminated independently. The contact mentioned that the emergency brake illuminated and was only able to operate the steering wheel. In addition, once the vehicle was stopped, the vehicle operated normally. The vehicle was taken to the dealer where they informed the contact that the failure was caused by a bug splatter. The vehicle was not repaired. The failure recurred. The vehicle was taken back to the dealer but was not yet diagnosed. The manufacturer was notified of the failure and provided a case number. The approximate failure mileage was 24,700.

The car automatically engages the braking system while in motion, each time this has occurred I was driving on a city street between 25-40mph. I have taken the vehicle to Nissan service center 3 times and they have been unable to fix the issue.

Automatic emergency braking engaged while was approximately 4 car lengths behind a white Ford f150 making a left turn.

The car brakes on its own when nothing is around . I was on city street.
