e Nissan Automatic Emergency Braking (AEB) System

Who is Nissan?

Originally founded in 1911 in Japan as Kwaishinsha Motor Car Works, Nissan has become one of the world’s leading automobile manufacturers. The company did not become known as Nissan until the 1930’s just before they became involved in the manufacturing of vehicles in 1933. After a couple more name changes and various foreign partnerships, Nissan began to create innovative engines and Datsun sports cars that would help them distinguish themselves from their competition. The company began its worldwide expansion between 1950 and 1970 as they became aware of needs in the market that they could fill. Over the next few years, Nissan would have factories in the United States, Mexico, Australia, Taiwan, New Zealand, the United Kingdom, and South Africa.

After facing severe financial hardship in 1999, Nissan formed a partnership with Renault. The company not only rebounded but was catapulted into a successful era that even economists couldn’t have predicted. Today, Nissan has production plants in 16 different countries, meaning that Nissan vehicles are manufactured all over the world. The company has research and development centers across 11 countries and boasts some of the newest and most innovative technology. While this may seem enticing, we still must ask—Is the innovation worth the defects?

What is the Nissan Automatic Emergency Braking (AEB) System?

As the name indicates, Automatic Emergency Braking (AEB) is a Safety System that automatically triggers a vehicle’s Braking System in case of an emergency. By using radars, sensors, and cameras, AEB technology can detect a potential collision. Automatic Braking Systems are usually coupled with Forward Collision Warning (FCW), a warning system that visually and audibly informs the driver when a potential crash is about to occur. If the driver doesn’t brake in time, the AEB System is triggered to stop the crash from occurring. This may seem like cutting-edge technology in the advancement of active safety systems—but for Nissan, the flawed AEB and FCW systems are proving themselves to be more dangerous than helpful for drivers.

While there is no definitive answer to why the System is flawed, there’s reason to believe that the defect originates in the radar modules of the Automatic Emergency Braking System. The module itself is defective in that it falsely informs the braking system of an imminent collision when there isn’t one. Not only does the System randomly brake when there is no chance of a collision, but it also randomly deactivates itself due to an “obstruction” that it falsely detects. In this case, AEB doesn’t work at all. Many consumers have made complaints to Nissan about this issue, but the company has yet to issue a recall or even take accountability for the problem. Some Nissan owners have gone as far as to file class-action lawsuits regarding the dangerous and defective AEB Systems in Nissan vehicles.


Can the Nissan (AEB) Automatic Emergency Braking be turned off or disabled?

Yes, Automatic Emergency Braking can typically be turned off or disabled. You can do this by pressing the right and left arrow buttons on the steering wheel until the settings display on your screen. You can then use the up and down buttons to scroll through the listed settings. By selecting “Emergency Brake”, you can choose to enable or disable both Front and Rear Emergency Braking Systems.

Is Automatic Braking worth it?

In theory, Automatic Braking is worth considering when purchasing a vehicle. An Active Safety System like this has the potential to protect you if a collision is imminent. Nissan’s Automatic Braking is known to be defective, therefore it does not seem worth considering.

Which Nissan Vehicles have Automatic Emergency Braking?

Automatic Emergency Braking Systems are included in 2018 or newer Nissan Altima, Armada, Leaf, Maxima, Murano, Pathfinder, Rogue, Rogue Sport, and Sentra vehicles. Nissan began to implement these systems about halfway through the year in their 2017 vehicles of these model types, so only some 2017 Nissans include the AEB system.

Are Automatic Emergency Braking Systems Dangerous?

If the System is defective like Nissan’s, it is dangerous. A defective AEB system could lead to collisions and injuries, which it was originally designed to prevent.

Other Common Nissan Defects

While Nissan is often known for its AEB and CVT defects, many consumers have experienced other electrical and engine-related issues with their vehicles. Some of the most common electrical issues that Nissan owners have mentioned affect their Backup cameras, Airbags and Airbag Sensors, Push-to-Start or Ignition Buttons, Infotainment Systems, Air Conditioning, and Heating Systems as well as their Windows and Lock Buttons. Consumers also state that they have experienced engine-related issues such as Oil Leaks and Engine Cooling Fan Failure. Beyond electrical and engine Issues, tons of consumers have also had issues with their sunroofs which can rattle or even explode due to the tempered glass they were made with. If you have experienced any electrical, engine-related, or transmission-related problems with your Nissan, don’t hesitate to give us a call—it could be a lemon!

Complaints from Other Nissan Owners

If you have experienced these issues, you are not the only one. From electrical issues such as AEB and infotainment defects to engine problems, other consumers have dealt with this and have spoken up about their experiences!

“My vehicle has suddenly and violently applied the brakes at least three times now. There are no other pedestrians or obstructions around my vehicle when this occurs. The vehicle has been to the dealership, but they apparently don’t know how to fix the problem. They will not let me take my vehicle home unless I sign a liability form. I am afraid that the AEB system will activate again on its own while I am traveling at a higher speed—this could cause a serious accident resulting in damage and injuries.” -2018 Nissan Leaf Owner (Automatic Electronic Brake Issue)

“I have complained to Nissan about this various times, and they apparently know about the Automatic Brake Malfunction. My husband and I were driving down the interstate one night going about 80 miles per hour when the system activated and slammed on the brakes. We started to spin, causing the traction control to engage and lock my tires. This caused the vehicle to spin even more, and we slammed into the guard rail. I have never been more scared for my life—we could have died. This issue can be added to the list with the transmission problems.” -2019 Nissan Sentra Owner (Automatic Electronic Brake Issue)

“Contact lost power driving at an unknown speed. Vehicle was towed to the dealership and diagnosed with Engine Control Module Failure. Vehicle was not repaired, and ECM was not replaced. Failure mileage was 28,000 miles.” -2017 Nissan Rogue Owner (Engine Issue)

“Push-to-Start button has given me trouble since 2020. When this occurs, I either must push the start button multiple times or start the vehicle with the fob. I’ve taken it to the dealership who claims there is no issue. I just dropped it off again.” -2018 Nissan Altima Owner (Non-Start Issue)

“Back-up camera often fails on infotainment screen and affects both the radio and air conditioning. When the vehicle is placed in reverse, the screen remains blank and does not turn on at all. The backup camera works only half of the time that I need it.” -2017 Nissan Pathfinder Owner (Infotainment/Backup Camera Issue)
