Brake Sensor problems of the 2008 Nissan Armada

Seat belt missing for rear back seat, delta sensor went out on me in a parking lot and I almost had an accident because my brakes wouldn't engage, and now my airbag spiral cable are now not working.

My "brake" light is randomly coming on when I'm braking or just driving on a city road or on the highway. There is a grinding noise when I brake in any of these driving situations. It's been doing this for about 4 years. I've had it looked at several times, but nothing is being identified. I've been reviewing a forum that is identifying this same issue with many other Armadas. It seems to be the booster sensors, which is a very expensive repair.

I left work and was driving down the highway and attempted to stop and the brake pedal began vibrating and the brake booster was making a horrid noise and I had to put the vehicle in low gear to get it to slow in bumper to bumper traffic. Today 03/10/2015 I received a letter regarding a class action lawsuit in regards to a sensor withing the brake booster stating I needed to file a claim in order to receive compensation for repairs, although the case has not been settled and the is no final court date until 05/15/2015 and we may not be reimbursed until September or later. . I need my vehicle repaired immediately and don't have time to file a claim nor do I have money to be out of pocket on a manufacturer defect. Nissan has not notified their consumers of this issue and this is the first thing I have heard of it from this law firm. I am positive there have probably been accidents directly related to this issue which Nissan seems to be covering up. Nissan needs to issue a recall and repair this brake booster immediately and nisaan consumers need to be notified immediately. This brake booster issue includes 2004-2008 Nissan titan, Armada, and Infiniti qx56 with vdc.
