While driving in traffic at 35 mph I pressed the brakes and they went all the way to the floor and the brake light came on. I turned the vehicle off and on and the brake light went off and the brakes recovered. Shortly after the brakes did the same thing again and I almost crashed into someone but was able to swerve.

While applying brakes, I noticed the brake light on the dash came on and that was followed by a serious reduction in braking power, shuttering, grinding and pulsing of the brake pedal. This continued until the car was stopped and turned off and then restarted. I almost rear ended a vehicle but was able to make a right turn at fairly high speed to avoid traffic. I have researched this all day and found that many Armada's in my year range are having the same exact problem.

- Humble, TX, USA

I was driving in a residential area and I applied the brakes while approaching a stop sign. When I pressed the brakes the brake pedal went down to the ground and a loud grinding noise was heard. The brake light came on and the slip light came on. The cars brakes didn't squeeze tight enough to stop the SUV within a safe distance and caused me to run the stop sign. It happened again a few days later while going at a higher rate of speed while approaching a stop light. In order to fix the problem I had to shut down the vehicle and restart it. It has happened a total of three times within three months.

For everyone with the brake issue on the Nissan 2004-2007. This is a faulty delta stroke sensor and Nissan has been aware of it since 2004. I just got off the phone with Nissan North America and was declined like everyone else because I am out of warranty. This has nothing to do with warranty. There are over 296 complaints on this website and the NHTSA has done nothing. There is a class action lawsuit for all consumers who own a vehicle with this issue under [xxx]. there is also an attorney for class action against Nissan for this issue as well her name is [xxx] at [xxx] law phone number is [xxx] I urge everyone to call her please.

While driving, the brake light came on and when I pressed on the brakes, the pedal went all the way to the floor and a grinding noise was heard. This has happened before. Took it into Nissan and I was charged about $100 to reprogram the system. That was supposed to have fixed but apparently it did not. Luckily, we haven't been in an accident yet.

As many, many other have stated on the Nissan forums, this vehicle has some dangerous braking issues. We have had our Armada for about 4 years and have experienced this issue at least nine times. Thankfully for us, it has not happened while we were on the freeway at high speeds or in a situation where we had to stop instantly. Here is an explanation of our issues: While applying the brake pedal we immediately heard a grinding and popping noise, as well as noises indicating that the ABS was activating off and on. The pedal was very soft and kicks back multiple times. The braking effectiveness was severely diminished. We have to pull over, turn the vehicle off and on again before we can continue driving. I find this to be a sever issue which is going to get someone killed, if it has not already. More than a few class action law suites have been filed for this issue in the titan truck, Armada and infiniti QX56 as they all share the same platform and parts.

I have already submitted complaint along with up of 200 others in regards to the faulty delta sensor in the brake booster causing the brakes to fail without warning, Nissan knows of this problem and does nothing, I am now prepared to go to abc news with all the information that I am collecting. I hope that they will see that the NHTSA is doing something about all the complaints they have received. I have not seen up to this point any open investigations. I hope someone doesn't have to die first. Thank you

The brake light came on and with no warning the brake pedal went to the floor and there was a digital type grinding noise with almost no use of brakes. Drove the vehicle to the near dealership and was told that they have been instructed by Nissan to reprogram a vdc unit. We were told that if the problem returns we are to need to replace a brake booster $818. So last week problem happened again without warning this time with my 3yr old daughter in the car and I was lucky that it did not result in an accident. $818 is a financial hardship for an obvious huge safety issue with Nissan. My understanding of others in the same situation is that the brake booster is not the problem but that the problem lies in the ABS but Nissan has no interest in the safety of their vehicles or the people driving them. The vehicle is parked as I am too afraid to drive it needing to drive up and down a mountain. I was floored to hear that this has been an ongoing issue with Nissan Armada owners and nothing has been done for a recall of this issue. I don't want someone to lose their life in order for Nissan to fix their problem. Please help!

The contact owns a 2004 Nissan Armada. The contact stated that while driving approximately 65 mph, the brake and vdc warning indicators illuminated until the engine was turned off. The brake pedal was depressed and then traveled to the floor with a loud clunking noise. On a separate occasion, the brakes failed to respond upon engagement. The vehicle was taken to an authorized dealer five times. The repairs performed on the vehicle consisted of the replacements of the ABS control unit, brake booster and master cylinder pressure sensor. The manufacturer was notified of the defect. The approximate failure mileage was 63,000.

As documented in the NHTSA complaints for multiple models and years. My Armada (that I happened to buy for my wife's birthday just 8 months ago), like thousands of other 04-06 Armadas, titans, and QX56 has the random ABS incident. This is a serious safety concern that I can't believe has not been recalled. Nissan knows about it. Dealerships know about it. People that have had their complete ABS systems replaced are having the problem just a few years down the road. The ABS system activates under normal, dry road conditions. The pedal goes to the floor, the vehicle loses almost all braking power, you hear the ABS grinding and feel it pulsating the brake pedal. The ABS light comes on, some times the "vdc off" and "slip" lights come on. It's documented on vehicle related websites by hundreds of users. www.titantalk.com. www.clubarmada.com. there have been vehicle crashes related to the ABS failure, there's probably been deaths (but how will those victims report the failure?)...people have reported having to pull off the highway at high speeds when it happens. People have reported not being able to stop for traffic. People have reported not being able to stop at stop lights and stop signs. But no safety recall. What does it take? I have two young children. They ride in this car. Does the NHTSA (and Nissan for that matter) not care about the safety of my family and the thousands of other owners with the exact same problem.

While driving my 2004 Nissan Armada le, I went to slow down to make a turn, and my brake pedal went to the floor accompanied by a metallic grinding sound. I downshifted and pumped the brakes to come to a stop, but had very little braking efficiency for the next third of a mile to my house. The brake light has periodically stayed on after the emergency brake was released, but turning the vehicle off and then back on has always reset this condition. After the incident today, the brake light remained lit even after restarting the vehicle. The brake pads, calipers, rotors, pistons, and master cylinder all appear to be in normal condition. I feel that our vehicle has experienced failure of the delta sensor or brake booster, as online forum descriptions of these sudden failures seem consistent with our experience. Nissan needs to act quickly to correct this failure to avoid driver injury or death. It appears that there is no open recall as of yet to address the faulty brake booster issue.

Was traveling down the road at 35mph! tried to stop at stop sign and the brakes failed! car would not stop! had to use the emergency brake!!!

- Ocean Springs, MS, USA

Car wouldn't stop. When I pressed brakes it would rattle and make a sound. I was going about 50mph when I tried slowing down brakes failed ! dealer didn't help at all!

- Oxnard , CA, USA

As I pushed on the brakes, there was a grinding sound and the car sort of shook (similar to ABS going off, but a little different, and I wasn't slipping). It was very hard for me to stop and the brake pedal felt very squishy. The emergency brake light came on and would not turn off. The problem would not go away until I turned the car off. As soon as I did that, and turned it back on the problem went away. This has happened multiple times since then, with no warning and under many different circumstances. No one can find the problem because it goes away when you turn the car off.

- Salt Lake City, UT, USA

The contact owns a 2004 Nissan Armada. The contact stated that while driving 30 mph, the brakes failed without warning. The vehicle was taken to an independent mechanic but they were unable to provide a diagnosis. The vehicle was not repaired. The manufacturer was not notified of the issue. The VIN was not available. The approximate failure mileage was 150,000.

- Forkland, AL, USA

Just recently I have had 2 incidents where randomly the brake light would come on and the vehicle would not stop. The vehicle made a horrific sound when applying the brakes and stopping power was probably reduced to about 20%. when the vehicle was turned off and restarted everything was back to normal. Luckily both times I was in a parking lot and not traveling fast. If I had been on a highway trying to make a quick stop it could have caused a fatal accident. I had the vehicle repaired at crown Nissan in birmingham al. They replaced the delta sensor and brake booster for 900.00+ dollars. It makes me wonder if these components should of been replaced when the brakes where replaced by Nissan under recall because of inadequate sized rotors. The delta sensor and brake booster could be inadequate for the new brakes that were put on my vehicle. I opened case xxxx3057 with Nissan North America to see if they would assist with the cost of the repair. They denied the claim and wouldn't even send me a follow up in writing after multiple requests. Seems they want to hide their decision.

I was slowing down for a stoplight. Applied brakes but little pressure and heard a grinding sound also the brake pedal was spongy. The brake light on the dash was on.

2004 Nissan Armada has a brake problem. The brake light comes on while driving. I have to turn off truck and turn it back on to reset break light. If I use brakes when light is on the ABS does not work, it makes a springy crunching noise when brake is pressed.the pedal went down so easily when it did this. Listen. Help. I understand that the problem is the call: "brake booster "or "master brake cylinder "is expensive and I check online and notice that many peoples already has this problem and not only 2004, also2005, 2006,2007 ! Nissan shall have this in re-call such that's very dangerous I tock the suggestion that write to this very important website thank you !!
