Lawsuit: Nissan Forward Emergency Braking Is Faulty

The class action lawsuit says that Nissan rolled out its emergency breaking system starting in 2015, even though it was “not road ready.” According to the lawsuit, Nissan’s automatic braking technology suffers from a “serious defect” causing Nissan vehicles to suddenly and unexpectedly hit the brakes when there is no risk of collision. Even when no cars are in front of the vehicle, the forward emergency braking system engages.

According to the lawsuit:

Due to the Emergency Braking Defect, owners and lessees of Class Vehicles have experienced sudden and unexpected braking on railroad tracks, on bridges, in intersections, and other driving situations that have placed them at serious and unreasonable risk of side-on or rear-end collision.

The lawsuit says that the faulty forward emergency braking on Nissan vehicles poses a serious safety risk to drivers, and as a result, it asked the court to force Nissan to issue a braking system recall or provide other remedial measures.

How many miles can you drive with the check engine light?

If you check engine light is flashing, we recommend that you pull over and contact Nalley Nissan of Cumming to help designate if your vehicle is safe to drive in or if we recommend a tow truck. The safest bet is to decipher the code and then plan your strategy accordingly. Since each check engine code has its own level of severity, it is complicated to predict how bountiful miles you can drive with the warning light on. It could be anything from a bad sensor to plug wires needing to be replaced.

What is wrong with the radar system?

The AEB/FCW systems work together to prevent collisions.  The cars are equipped with a series of sensors, radar and cameras, which support the FCW system that issues visual and audible alerts if there is an obstacle ahead. If a collision is imminent, the AEB system will engage and activate the brakes automatically.

It’s alleged that a flawed radar module makes the system frequently activate itself and suddenly stop the vehicles for no reason.  The radar modules are apparently creating false-positives and stopping the cars at random and unnecessary times.  Drivers are caught off guard by the sudden and automatic actions of the defective system that have caused approximately 14 crashes and 5 injuries that are known to date.

The system is also flawed in that it frequently deactivates itself and a warning message flashes on the dashboard “front radar unavailable due to obstruction.”  As a result, the radar system stops working resulting in the unavailability of both AEB and cruise control.

More than 1,500 complaints have been filed to date regarding the AEB malfunctions.  

Common Nissan Consumer Experiences and Complaints

Many consumers with a variety Nissan model vehicles and model years are experiencing issues with the automatic emergency braking system and have reported a wide range of complaints including but not limited to the following:

When I am driving with nothing in front of me, I will hear a beep, then a message comes up “Unavailable: Front Radar Obstruction.”

  • 2019 Nissan Sentra Consumer

When it is raining, a warning comes on my dashboard “front radar unavailable due to obstruction” and the car beeps and the warning icon appears.

  • 2018 Nissan Murano Consumer

When I am on the highway and either the car in front of me switches lanes or I switch lanes while a car is in front of me, the warning message pops up “Unavailable Front Radar Obstruction.”

Will the check engine light reset itself?

The check engine light on your Nissan Rogue will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it’s tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Nissan Rogue light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Nalley Nissan of Cumming so the light and code can be double-checked and reset.
