The airbag light has been on for a while indicating that there is a defect in the airbags. The brakes light comes on randomly and the car brakes on its own without me applying the brakes and that is very dangerous especially on the highway and the transmission light comes on showing the 4x4 light as on for no reason and I would have it on just the 2 wheels

Automatic transmission cooling line failure. Our automatic transmission cooling line sprung a leak without warning and no ignition lights turning on. The end result is that the transmission needs to be replaced. After doing some research online, I found out that this is a common problem with Nissan Armada 2006 transmission cooling lines. The line had a weak spot in it that split open and sprayed all the atf out. This occurred while driving back through our town at about 35 mph.

The vehicle differential control stopped working and caused a brake failure. The vehicle slide through a red light into an intersection where it was struck in the side by another vehicle. After the incident, I checked the brakes and it had stopped. This was one incident of many. The vehicle's brakes stop working and makes a grinding noise. If I turn the vehicle off and restart it, it will stop doing it. The vehicles brake pads, calipers, and brake booster has been replaced and it still continues to do it. There is no consistency to this occurring. It does this periodically with the same result. I researched the problem and it seems this is and has been a problem involving Nissan Armadas nationwide with serious consequences. There are tens of thousands of complaints being reported on the internet all of these complaints are described the same way. In fact I received a notice on a class action suite being filed against Nissan for this problem. I work for NHTSA and attempted to discuss this problem with ODI to no avail. I would expect some sort of response when me and the public make complaints that can and will be life threatening. How many complaints and or how many people need to be involved in crashes, injuries, and/or deaths before something is done. The incident described is one event among many. It has also occurred on the interstate at much higher speeds. The only way to clear it is to turn the vehicle off and crank it back up again. The dealer will not recognize there is a defect, instead they continue to replace brake parts, at the owners expense hoping this will fix the problem..

On approximately September 24, 2013 I was driving down my street heading to the store. When approaching a traffic light, I applied the brakes and the brake light went on and I had sudden loss of braking power, with a grinding noise, loose braking motion. The brake pedal actually went all the way down to the floor panel. I was able to stop vehicle, although I had approximately 70-80% reduced braking power. Imagine how scary it was to try and stop a 6,000lbs vehicle with only 20% of your normal braking power. I came within inches of hitting the vehicle in front of me. I turned the vehicle off and back on and problem was gone when I restarted. I took it in to my mechanic, who attempted to see the problem for himself. However, it did not repeat the same symptoms. Therefore, he couldn't diagnose the problem. A few days later, it happened again. I went immediately went to my mechanic so that he could see the problem for himself. Unfortunately, he wasn't in but one of his employees test drove the vehicle. Since I didn't turn off the vehicle this time, he was able to experience the trouble I was having. I returned to my mechanic the next day and he advised me that I should contact Nissan to find out if it's a recall item since his research showed that many people have complained about the same exact problem. I have already sent inquiries through the Nissan website. However, no response has been given. I have had re-occurrences on numerous occasions and the frequency has been increasing. As a matter of fact, as of recently, now all the lights on my dashboard go on for no apparent reason, then I lose braking power. I use my vehicle for work. This could become a real issue. Especially if it results in an accident or worse. Why is Nissan not owning up to their responsibilities?
