2019 NISSAN ALTIMA Forward Collision Avoidance Automatic Emergency Braking Problems

While driving my Nissan Altima in normal operation, the vehicle suddenly and unexpectedly stopped and applied the brakes without any input from me. This occurred without warning and created an extremely dangerous situation. There were no other vehicles, obstacles, or apparent reasons for the vehicle to engage any safety systems. This is a critical safety defect that could have resulted in a serious accident. I was fortunate that no vehicles were following behind me, but this incident could easily cause rear-end collisions or other accidents if it occurs again.

Well, first, my struts are bad on the right wheel. And I've went through about 5 tires now. And I guess my wheel bearing or something is messed up too. I don't I don't know exactly, but it does not sound good. Next would be the brake light is on and it won't shut off. No matter what I do, it will not turn off. The third thing is my cameras are not working, right and the fourth thing is, as it's making some kind of weird noise. I don't know if it's the engine or it could be where the wheel is. I don't know

I have a 2019 Nissan Altima SR 2.5. I have currently had the car for about 3 or 4 years now. For most of the time I have had the car, the check engine light stays on. I have had it tested, and it always states that it is the Mass Air Flow Sensor. When sitting in park idling, it will "malfunction" and state that the engine is reducing power. During this, the automatic emergency brake warning light and the VDC light will come on. It's rare that it happens while I am driving but it has happened. I recently had the vehicle checked again and again it stated that the Mass Air Flow Sensor and the Grille Shutter Actuator were throwing codes along with some other minor items. I purchased the MAFS and replaced it in hope that this would correct a lot of the idling issues, however after...

Engine Failure while driving. While driving on NJ Turnpike, Engine light appeared on dashboard. Car began to jerk and immediately lost speed from 70 mph to barely 15 mph. The vehicle continued to jerk then rolled to a stop. Vehicle has had regular inspections, repairs and oil changes completed. Engine Malfunction Reduce Power lamp comes on occasionally and goes off after a few minutes. A State Trooper stopped & said I may call #95 if unable to get off at next exit. No Report was made. Problem with engine failure started on 08/08/2025. Vehicle is parked, I am afraid to drive vehicle because I have to stay in Far right lane or on shoulder with hazards when driving. I have an appointment with Nissan Edison NJ on 08/10/2025 to check if my vehicle is eligible for Upcoming RECALL. There is a Recall for 2019 Nissan possibly coming the End of...

Driving down the road and my parking brake light came on when it wasn’t in park and i was on a highway. Malfunction light came on, but car runs fine and had it looked at with no problems.

Hello, Please see all attached documents and call me for further details and assistance prior to investigation. I appreciate your time and assistance. Thank You

I saw the recall about the backup camera malfunction however my car isn’t listed for the recall but for the last few months my backup camera has been saying malfunction and doesn’t beep. I’m trying to see if I could receive the recall to get this fixed.

Emergency brake engaged when there were no objects near the vehicle. Vehicle stopped. The dealer stated the issue was due to a faulty sonor control unit.

Adaptive Cruise control and Forward Collision warning has failed. The cruise control will not engage. The Electronic braking system has malfunctioned and this has somehow disabled the cruise control on the vehicle. The car will still brake. I understand that this has been known issue with Nissan but they are not willing to repair it.

Numerous times since I purchased this car used, the auto brake assist will go off unexpectedly when going under bridges… it almost caused me to loose control of my car numerous times. In addition. The malfunction warning light will randomly turn on even on beautiful sunny days with car being clean.

Please note that I have my car regularly inspected for oil changes and maintenance. The adaptive cruise control stopped working August 2022. The car displays "malfunction" on the dashboard. This was inconvenient and at first intermittent, but I did not think it was putting any persons safety at risk. I went to a local Nissan dealership in NJ and they stated it would cost $600 to replace, but no safety issues. Therefore I did not get this fixed at the time. On March 14 2023, I was merging onto a highway in daylight around 4pm. It had started flurrying, but no changes in visibility. There was no car immediately in front of me. The collision warning suddenly came on and the emergency brakes were activated while attempting to accelerate onto a 65 mph highway in NJ. It was extremely startling. It certainly could have caused an accident, especially when vehicles...

Automatic brake system malfunction

2019 Nissan Altima is experiencing judder when switching between gears at low speeds. Also automatic breaking system (ABS) activates when I attempt to park.

08/24/22 driving on a three lane highway with no cars in front of me in any lanes, no pedestrians, animals or any obstacles going 50 mph, the car just stopped and the forward collision warning activated and the car stopped. Took the car in to the local dealer 09/08/22 where technician noted they could not replicate the issue on test drive. Dealer service pointed the issue to 12/2021 accident and wanted to charge me $2,020 to fix. Car has less than 17K miles and is under warranty.

I have Nissan Altima 2019 SR. It has an automatic front emergency brake system that brakes when the car is close enough to save from an accident to occur. But it did the opposite means it risked my life by braking in the middle of the road in traffic even if no cars are in front of me. I was saved a couple of times because there were no cars around me when it did that. But it seems very dangerous and risking life and other around my nissan car. I contacted customer service, they told me I have to pay for that repair. It is ridiculous. How to find justice on this issue? Is this a way these car companies make faulty systems and risk human lives? Do I deserve this? Please help me to solve this problem.

My fiancé and I were driving late at night on a straight, one lane road going just over 40 mph with NOTHING in front of us. For no reason the pre-collision front sensor went off indicating we had the potential of hitting the vehicle in front of us even though there was nothing there. Moments later the dashboard went white showing a red triangle and the automatic braking system came on engaging all the brakes and abruptly reducing the vehicle's speed to approximately 15mph before it disengaged. That this time we had no control over the speed of the vehicle and could only steer the car to the side of the road. Had another vehicle been behind us there would have been an awful accident where us and the driver behind us would have been injured as there is no way anyone could have anticipated such an inappropriate speed change...

The forward AEB system warning light illuminated at 47,124 miles. I parked the car, turned it off and then restarted it and the light remained off for about 5 miles before re-illuminating and remaining on continuously. While I was driving, the car began braking at random times when there was no vehicle in front of me, and would decelerate to 40mph sporadically. I ended up pulling over on the highway and having the vehicle towed to my office until I could afford to have it taken to a Nissan dealer. I purchased the vehicle used on June 8, 2022 and this malfunction first occurred today, June 13, 2022. Per the service records, there is no other notification of this malfunction occurring prior to this incident.

The car regularly automatically slams on the brakes for no reason when there is nothing ahead of me. While in parking garages, turning on divided highways and worst of all while crossing railroad tracks. Dealership just brushed off my concerns because it wouldn't do it for them, and I don't think they checked my car at all. I also get a collision system malfunction warning, sometimes while driving and other times while sitting still. This is DANGEROUS, one day I will either be rear ended or God forbid hit by a train.

Forward Emergency Braking/Collision Warning - Activated without cause or other indication - The vehicle suddenly applied brakes - then released them - two occasions - on 01/21/2022 a New Castle County Police Department vehicle following me swerved into adjacent lane to avoid collision Dealer service was unable to replicate event/s - no other vehicle inspections. No other previous indicators or warnings, Second event occurred on 01/23/2022 at about 30 mph.

I was driving to work and all of a sudden the warning came on for the front radar malfunctioning. I have taken my car to the dealership where I get the oil changes and was told that Nissan would not cover it. I was told I needed a front distance bracket and quoted almost $800 for repair. The rep told me that the mechanic said I had a aftermarket bumper on my car and i explained that my car was in an accident twice in the months of april and may. but that should not be the reason of the problem because the light was never on my car when both accidents ocurred and after repairs. We are in the month of september why would it be on now? This is my only source of transportation and I feel for my safety with this car that something else could happen...

The Automatic Emergency Braking System continuously brakes and slows the car down when driving. One particular incident happened on 6/15/2021 when I was travelling at 45MPH and there we cars behind me. The system beeped as if it detected a crash and then stop the car. There were no other cars in front on me and I almost got into an accident because of the sudden braking. There were no warning lamps, messages, or anything else that would prompt the vehicle to immediately break. It has done this 3 more times in the last two weeks and its hazardous to me and other drivers on the road. Now every time I put my vehicle in drive it says AEB malfunction and the vehicle no longer detects forward collisions or any passengers. I haven't taken the vehicle to the dealership yet; however, I had an oil change and when the dealer...

driving at maybe 10 -15 MPH in an empty parking lot about to park and car aggressively brakes for no reason. Completely startled and unsettled me its a good thing no one was behind me.

I HAVE HAD TWO SEPARATE INCIDENTS 8 MONTHS APART. WHILE DRIVING IN THE CITY LIMITS ON BOTH OCCURRENCES GOING ABOUT 45 MPH BOTH TIMES, WITHOUT ANY NOTICE OR POTENTIAL COLLISION THE AEB ENGAGED, AND A RED FLASH CAME ACROSS MY DASHBOARD. THE FIRST TIME IT WAS JUST ME IN THE CAR WITH VERY LITTLE TRAFFIC AROUND ME, WHEREAS WITH THE MOST RECENT OCCURRENCE THE TRAFFIC WAS HEAVIER. I HAD MY MOTHER AND 2 YOUNG CHILDREN IN THE BACKSEAT, WITH A TRUCK THAT LOOKED LIKE A F-150 NOT FAR BEHIND ME. I HAVE BEEN TO THE DEALERSHIP THAT I BOUGHT THE CAR FROM, AND I HAVE TWICE GOTTEN THE RESULTS THAT THEY ARE UNABLE TO DUPLICATE THE PROBLEM, SO I GUESS IT CAN'T BE RECTIFIED. THANKFULLY I HAVE NOT HAD AN ACCIDENT, BUT DRIVING THE CAR IN THAT CONDITION RAISES THE RISK OF A COLLISION, AND I'M DONE WITH THAT RISK.

WHILE DRIVING STRAIGHT OVER THE UPPER ROADWAY GW BRIDGE, MY AUTOMATIC BRAKES ENGAGED WITH NO OBJECTS IN FRONT OF MY CAR. THIS CAUSED MY FRONT BRAKES TO LOCK WHICH CAUSED ME TO DRIFT LEFT INTO THE LEFT LANE, AT WHICH POINT I WAS ALMOST CRUSHED BY A SPEEDING 18-WHEEL TRUCK.

I WAS DRIVING ON A SLIGHTLY DAMP ROAD IN THE EVENING (DARK). A WARNING FLASHED ON MY DASHBOARD SAYING THAT THEIR WAS OBSTRUCTION IN THE ROAD. SUDDENLY MY BRAKING ASSISTANCE ACTIVATED CAUSING MY CAR TO COME TO A COMPLETE STOP. I CHECKED MY SURROUNDINGS, NOTHING WAS IN THE ROAD, BESIDE ME, OR BEHIND ME. NISSAN HAS NOT CLAIM RESPONSIBILITY FOR THIS SENSOR ERROR. INSTEAD TOLD ME THAT THERE WERE DAMAGES TO MY BUMPER, WHICH WAS HARD TO BELIEVE. I WAS RECOMMENDED TO CONTACT MY INSURANCE COMPANY. AN APPRAISER FOUND NO DAMAGES TO MY CAR OR BUMPER. CASE HAS BEEN DISMISSED BY INSURANCE COMPANY.
