2019 Nissan Altima FORWARD COLLISION AVOIDANCE

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.

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 are accelerating to merge onto a highway. I was fortunate that there was no car immediately behind me. On April 26 and 27 2023, the emergency brake was activated again due to a collision warning while in a parking garage. The only correlation I can think that ties these occurrences is when driving from a shaded to sunny location. All three times it also occurred during acceleration. This new problem is quite concerning and dangerous.

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.

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 at that time. I brought the vehicle into the dealership days later. They could not duplicate my concern. They found past trouble codes of C1A16 & C1A17 on the vehicle's history. They recommended calibrating the distance sensor and road tests but were not confident this would fix the problem and stated a new sensor may need to be purchased. Upon experiencing this traumatic event in my Nissan vehicle I posted my experience on Facebook and had 3 people I personally know reach out to me saying they experienced similar events in their Nissan. All the people had 2017 or newer Nissans vehicles that included the Sentra and Rogue models. No warning lamps, messages or other symptoms of the problem appeared prior to the failure besides the pre-collision sensor incorrectly coming on as described above. The vehicle is available for inspection upon request.

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.

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.

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.

The forward collision warning malfunctions and a warning light is displayed. This used to be an intermittent problem which now occurs every time I drive the vehicle. This is an important safety feature in the vehicle.

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 inspected my vehicle they said everything was in good shape. I'm not sure how this was missed.

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 while I'm driving and I pray that it don't. The same day it started malfunctioning a small animal ran under my car. It has been times that while on the highway othere drivers would cut me off or get to close and my sensor want alert me. Thank goodness I be watching the road.
