Sometimes systems break or malfunction. Faulty modules used in Nissan Intelligent Safety Shield Automatic Emergency Braking systems are not working properly on Nissan Sentras and possibly other Nissan models such as the Nissan Altima, Armanda or Murano.
Update 10/9/19 NHTSA is investigating the problem over 129 complaints for a possible recall.
Update 1/31/19 We have contacted Nissan about the problem and they have made a statement. There are also two class action lawsuits on the matter.
The problem apparently is caused by a radar module in the front grill supplied by Bosch. New Sentra owners are getting warning error messages, “Front radar unavailable due to obstruction.” when the module is not covered. The Bosch component deactivates and disables both cruise control and emergency braking.
Nissan told Digital Trends that it is aware of a relatively limited population of Sentra customers who are reporting the problem and it’s engineering team has identified the cause to be a supplied-component issue. Nissan is working on finding a solution and getting it to their dealers for replacement. Apparently it is Bosch Radar sensor make in Hungary for Nissan part number (28438-5UD2A) that has a MSRP of $753.67 which can also be found in Nissan Sentras going back to 2016.
A similar model sensor is found on the 2018 Nisan Murano, Nissan Altima, Murano, Pathfinder and Leaf.
The problem with a faulty AEB sensors is that most consumers have no way of checking if automatic emergency braking system is working. It is most likely a newly identified flaw. Nissan notes that the problem does not effect driving ability. Nissan also notes that the warning is doing its job, and critical safety systems are not affected.
The 2019 Nissan Sentra, went on sale starting August 14 at Nissan dealers nationwide. For the 2019 model year, all Sentra grades (except Sentra S) receive standard NissanConnect with Apple CarPlay and Android Auto. AEB is standard on all Nissan Sentras with Xtronic transmissions.
Nissan Safety Shield 360, a suite of active safety technologies, are available on the all-new 2019 Altima and 2019 Rogue – both on sale this fall.
Using radar technology to keep an eye on your speed and proximity to the vehicle ahead, AEB (formerly Forward Emergency Braking) gives you audio and visual display warnings to help you reduce your speed if necessary. If a collision is unavoidable, this feature will engage the brakes to help reduce both the speed of the impact and the severity of a collision.
We have been getting comments from frustrated Nissan owners who have experience either the software notification problem or Automatic Emergency Braking (AEB) engaging in inappropriate situations.
Some of our readers have reported success by taking their affected Nissan Murano, Sentra, Altima or Armada to a different dealership, that was able to get the correct part and at least replace the sensor.
We have learned that it may be better for Nissan owners with the problem to opt-out of class action lawsuits, if you would prefer to have Nissan buy-back the car and then buy an alternative vehicle.
The opt-out process must be documented via sending a certified letter with return receipt or email confirmation.
We also suggest that you document every dealer visit. Often the dealer is not putting the correct information into the service form and customer invoice. We are hearing that because Nissan will not pay the dealer for certain things that they turn away the customer.
When you set up an appointment either go to the individual dealership or http://www.nissanservicenow.com
It should show you offers at your local dealerships, click or tap on “Schedule APPT.”
The fastest way to schedule is to use “I’m in hurry”
If you tap on EDIT you can choose a service and have the option of filling in more information.
Here’s the tricky part. When you get to the dealer, show them your appointment and make sure that they show your comments in the work order aka repair order.
We have heard that dealers are not fully documenting repair orders and then come back later and say the customer did not make the dealer aware of a problem.
A general rule in all of this is get documentation in writing.
If you are hoping for a class action, it may mean that the vehicles stay on the road until the automaker works on a fix, putting you and your passengers in danger.
We also suggest that you file complaint with NHTSA. When there are enough major problems submitted there, the automaker is forced to seek a solution and recall the vehicles at no expense to the owner.
