My brakes lock up on my 2005 Nissan Armada completely. The vehicle rattles and the front part makes a noise as if it is breaking apart. There is no warning when this is going to happen. The brake pedal locks and springs back. I turn the truck off for a few minutes and the issue goes away. Other owners are having the same issue with the brakes electrical system.

My 2005 Nissan Armada's air bag SRS system is inoperable. The dashboard light indicated a failure of the airbag system while the vehicle was under warranty and I thought it was repaired after several instances. I have taken the vehicle to several mechanics to have the SRS system repaired. Nissan claimed it has been everything from the seatbelt tensioners, sensor modules under the seats to bad electrical connectors. All of these components have been replaced but my dash lights show I still have inoperative airbags. The SRS system on my Armada is currently in failure again and I cannot afford to pay Nissan again to attempt to repair the problem. I also have a second issue with the ABS brakes activating randomly during normal slow speed stops in which the brakes shake violently and with little stopping force. It seems the ABS system is activating under light operational conditions. This has been a re-occurring problem each summer. Nissan cannot duplicate the problem so I have been sent home without remedy. I am complaining because I have no other recourse except to warn others before someone is seriously hurt or killed through the failure of the brakes or the airbags. I am the original owner and the vehicle has not been modified in any manner.

My husband was leaving work in 2005 Nissan Armada, he heard a strange grinding noise coming from front brakes as he tried to stop at a stop sign then realized he had no brakes. He managed to drive the 10 miles home with no brakes. We drove to nearest Nissan dealer the next day and was told it was an electrical issue in the master brake cylinder and would cost $900 to fix. After checking online forums we realized this is an issue with many more owners, that Nissan fails to do anything about. How many people have to get seriously hurt before Nissan will admit that there is a serious issue with the brakes for this model.

I have a 2005 Nissan Armada, the problem is complete brake failure. When traveling at slow speeds (<20mph) the brake system gives out completely. The brake pedal goes to the floor, the red brake dash light comes on and the ABS and vdc systems go into a confused array of mixed signals and sounds trying to correct the failed brake system. At the time of failure the braking power is <25% of normal. In a panic stop or while trailering a load there would be no way to avoid a crash and injury. This failure occurred 5 times in one day before the vehicle was towed to Nissan. The scariest part of this failure is that by turning the vehicle off and restarting it, resets the system failure and everything functions completely normal for a time, leading the driver to believe that it was just a computer error that needed reset. Nissan reported that it was code C1179, delta sensor failure and required a new delta sensor and brake vacuum booster. The vehicle currently has only 39,458 miles on it. This is a major safety issue, this vehicle is rated to tow 9100lbs, when the failure occurs the vehicle can barely stop its own weight. The stopping distance during failure going 20mph was approx. 200 to 300 feet with only one occupant. Nissan knew exactly what the problem was when I called them so I am not the only one to have this occurrence. Upon researching I found 48 complaints that match mine on aboutautomobiles.com. These people all took the time like me to create an account and voice their concerns in much detail. This is a manufacturing defect that should not be occurring on any vehicle. Please correct this problem before someone gets hurt!!

The contact owns a 2005 Nissan Armada. While driving approximately 15 mph, the contact applied pressure to the brake pedal and the brake pedal fell to the floor. The contact heard a grinding noise coming from the brakes. The vehicle was taken to the dealer where the technicians stated the brake booster needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and stated the contact would be responsible for the cost. The approximate failure mileage was 103,000.

I have a 2005 Nissan Armada that has had anti lock brakes engaging at all different times in conditions that it should not be engaging in(example:sunny, clear road,90 degree summer weather)this leaves me with very little braking ability.this is a major safety issue especially when I have small children in my vehicle. I have brought it to the Nissan service dept. Several times and they tell me that everything is fine and cannot replicate the problem. I have googled the problem on the net and found numerous sites with pages upon pages of complaints over this same problem with my exact scenarios of driving conditions and what happens to the vehicle. I proceeded to Nissan headquarters to explain my problem and that I am not the only one that Nissan has failed to help. They refuse to recognize that this is a major safety issue happening to numerous Nissan Armadas years 2004 thru 2006. I said I want a rental paid for by them and I want Nissan to keep the car till they can rectify this obvious wide known safety problem. They told me that Nissan is not responsible for this problem nor acknowledges it & that the vehicle owners are and at vehicle owners cost to drop off the vehicle for a undetermined amount of time(this could be a week to many weeks before problem occurs again & it is stated by numerous owners that is how undetermined when it happens)till they can hopefully replicate the problem and repair it at owners cost along with rental vehicle cost. This is not a wear and tear problem caused by the owners of this vehicle model this is a manufacture defect that Nissan refuses to admit and create a recall on this anti lock brake system. They also proceeded to tell me that if I can't afford a rental for who knows how many weeks that it could be to wait till the problem occurs myself and drive it to the dealer. That is a unacceptable unsafe answer form them to tell the consumer to drive your vehicle till you have no brakes then bring it in. Something must be done!

2005 Nissan Armada brake hydraulic failure. It happen at least once every other month ever since I own the Armada back when it's about 15K miles. While driving at low speed and coming to a stop, the brake light led up and the braking system is useless, it make grinding sound, sound like springs popping out in front of the Armada from tires. Almost crash the Armada into another car stopping in front several times due to useless brakes. Took it the mossy Nissan houston, they can't "replicate" the issue back years ago. Once you shut off the Armada, it reset and it went back to normal. And the problem continue, perhaps until someone get hurt or kill"????"!

While driving down the road I would be approaching a stop sign or light and I applied the brake and suddenly hear a loud grinding noise. When I pull over and turn the vehicle off and then start over, it was like it reset itself. I freaked out because I had children with me. Nissan, please figure this out!!! also when I try to turn my air on or off I hear a very loud clicking noise. Even while driving down the road without touching the air it just randomly does it.

11/10/10 while driving the brake light came on and the truck was not responding to the brakes I heard a grinding noise and the problem went away after I turned the truck off and restarted it. It has happen like 4 times to my wife while driving with my kids so im very concerned about this problem. I went to the dealer and all they could say was that they needed to get the code for them to try to find out was wrong with it. If there's someone out there that can help before its too late and something serious happens.

I own a 2005 Nissan Armada and on at least 4 occasions my brake light has come on while driving. When I apply the brakes they make a grinding noise and the vehicle vibrates and the brakes are not effective. So far I have not had anyone in front of me nor have the traffic lights been red. If they had I would have been involved in an accident. I have had to coast to the edge of the road or turn into a parking are. When I turn the vehicle off and re-start it the problem disappears. I went on line to a web site listing problems with the Armada and find that mine is not the only one doing this. I think you need to recall these vehicles as there is something wrong. I know you wont as in my opinion most of you worthless government employees are useless and don't give a [xxx] about the safety of the citizens of this country. Last happened October 10th 2010.

On 10/21/2010 the right rear brake caliper fell off of our 2005 Nissan Armada during vehicle operation. Dealer inspected and stated caliper bolts were "missing" and my wife "had someone watching over her" and was lucky to not have sustained any injuries. Vehicle has had no recent service to rear wheels or brakes. Vehicle has approx. 77,000 miles. Dealership has no explanation for incident other than vehicle being "tampered with" and tried to use theft of catalytic converters as an example.

I was operating my 2005 Nissan Armada on Monday, September 20, 2010 when my brakes failed to operate correctly. Fortunately, it did not cause an accident, but the brakes when applied did not cause the vehicle to stop and there was a grinding noise when I applied pressure to the pedal. I had the vehicle towed to the dealer where they discovered a code C1179 which required them to replace the brake booster sensor. The repair was over $800 which included the cost of towing the vehicle. I have learned that Nissan issued a service bulletin for the issue on May 12, 2006. My husband complained to Nissan, but they would not cover the cost of the repair. My vehicle had approximately 79,000 miles at the time of the incident. I am concerned with this issue because it was a failure of a safety system of the vehicle which I do not believe to be associated with normal wear and tear. In my situation, I had just replaced my front brake pads two months prior to the incident. My vehicle was well-maintained and regularly inspected by the dealer.

Previously reported under complaint #ODI id number : 10339985. A summary of the problem:the issue/problem: The brake light comes on. When brakes are used, there is decreased braking power. The brakes make a crunching, springy noise with the pedal being extremely soft until it gets closer to the floor and begins to give braking power. When ignition is turned off, the problem resolves at least temporarily. When the engine has turned off, I have had the problem reoccur as soon as 5 minutes and as long as 31 months. I made a video of one of my instances @ www.youtube.com/watch?V=bmtpofdbjr8 I first experienced the braking problem back in 3/06 with ~12,000 miles on the vehicle. The dealer was not able to duplicate the issue, but it had happened to me 3-4 times prior to getting it to the dealer. During the visit, they performed the judder brake bulletin service. The description of the judder brake bulletin did not seem to fit my problem, but the car no longer had the issue. Then the issue recurred at ~46,000 miles in 10/08. Again the brakes did not have full power for 3-5 times prior to getting it to the dealer. I was able to demonstrate the problem to my local mechanic, but when he shut down the engine, the problem resolved. I returned the car to the dealer. The computer did not have any repair codes stored, but they performed tsb 06-040, a computer software update. The car was fine until 6/25/10 when the problem recurred. It occurred three times throughout the day. I started tracking the occurrences: 6/27 X 1, 6/28 X1. I made a appointment with the service manager at the dealership on 6/29. I kept the car and it reproduced the problem 7/1 and 7/4@ 70,697miles. I made arrangements to allow them to take the car and get a loaner so that they could hopefully reproduce the problem. During this July 10 visit they had the car over 3 weeks and completed 2 software updates @ nc. On 9/2/10 @ 72,449 miles, the braking prob has recurred.

Nissan 2005 Armada 4X4, 50 K miles. 94 degrees sunny weather in rancho cordova, brakes completely failed in the lowes parking lot. There was some grinding noise but no forceful grip of the rotors. Brake light came on. I slowly pulled over into a available parking slot, turned off the vehicle turned it on again in 2 minutes and the problem disappeared. People have been reporting similar issues www.clubarmada.com/forums/showthread.php?T=16698 please investigate the issue before it results in serious accidents.

ABS brakes engage while driving which causes a loud grinding noise to occur when I try to apply my brakes. The braking system does not seem to engage. It has happened 6 times in the past 8 weeks. The last one occurred 08/23/2010.

When driving to work and going over a speed bump the brake light came on. The brake pedal went to the floor. I then started to feel the brake pedal vibrating, as if the ABS had kicked on. This has happened several times. I proceed to pull to the side of the road and turned the ignition off. I learned that by doing so the computer resets itself and it goes away. I am concerned about this problem. I tow three quads in the weekend to have some fun, but I don't want to get into an accident when going down a hill on the way to my destination. I also carry my kids and that is my main concern. I have took it to the dealership and they don't see anything wrong with it" they could not duplicate because it doesn't happen often. I suggest checking the 05 on a downhill, that always seems to cause it to happen"

- El Monte, CA, USA

In the most recent incident, I was driving the vehicle at slow speed (approx. 10 mph). When brake pedal was depressed, it went to the floor and the nose of the vehicle dove down. Front brakes made a loud banging sound and vibration could be felt in vehicle cabin. There was a considerable reduction in brake performance, to the point of failure. Brake light in vehicle illuminated as well. These same symptoms have occurred at various speeds, under various driving conditions more than a dozen times over a period of one year. Vehicle was taken into local dealer today and a full description of the problem was provided. Dealer re-programmed vdc (code 1179) at a cost to me, but would not guarantee this would permanently fix the problem. If problem persists, dealer recommends delt stroke sensor/brake booster replacement at considerable cost to me. At higher speeds, this condition could be deadly.
