In specific cars, if a collision is likely and the driver is unable to intervene as fast as necessary, the automatic emergency braking (AEB) systems will brake automatically. AEB can identify a probable collision and trigger the braking system to slow the vehicle down to lessen or reduce the impact of the accident. A lot of AEB systems combine radar and camera technology, which are positioned on the front of the car or embedded inside the windshield.

Usually, these radars and cameras are used to detect factors that could cause or give rise to a collision. If they identify a dangerous object and the system does not receive any indication from the driver to avoid it, the AEB system will be activated automatically.

The AEB system was designed to add another set of eyes to help you prevent a collision. The technology provides the driver with an additional layer of safely driving by identifying and automatically applying the brakes. However, when it malfunctions or does not work properly, you will need to know the symptoms and where to go for assistance repairing it.

Causes of a Defective AEB

Some vehicles can abruptly stop due to anomalies in certain Nissan‘s automatic emergency braking systems, despite there being any obstacles to avoid. This can put the drivers and other people on the road in danger. Some of the radar modules on the car’s front grill may be defective. This results in false positives, causing the car to stop abruptly for no apparent reason. This also can lead to causing more collisions than it prevents.

Drivers may receive a message stating “front radar unavailable due to obstruction” frequently followed by the sensor deactivating. Both the AEB and cruise control will be disabled once the radar is unavailable. Several variables cause the brakes to be activated unnecessarily. They include bridges, steam from underground pipes/manholes, railroad tracks, and parking garages.

Signs of a Faulty AEB System

There are a couple of indicators that indicate your Nissan’s automatic emergency braking system is malfunctioning and needs to be fixed. To avoid unsafe circumstances on the road, it is advisable to take your car to a trusted mechanic as soon as possible once you notice any of these concerns.

  • A Sudden Stop: The AEB sensor may be obstructed or malfunction if the car suddenly stops without your intervention. In most circumstances, if the sensor identifies an impediment straight ahead, and the vehicle is traveling faster than 15 miles per hour, the car will abruptly brake to avoid a collision. A faulty sensor might send out false-positive signals, leading the car to respond unexpectedly.
  • Stalling: Once your vehicle suddenly slows down without you using the brakes with no obstructions in front of it, you should seek advice from a trained mechanic as soon as possible. The AEB is not to be activated if the vehicle is traveling at less than 10-15 miles per hour. A malfunctioning AEB could be the cause of stalling in places like parking lots or garages.
  • Difficulty Starting the Car: If your car is having difficulties starting, it could be as a result of an AEB issue that is turning it off because it is expecting a collision when it is not. If the starts fine but then shuts off after a few seconds, this is most likely the case.
