Air Brake Related Problems of the 2010 Nissan Armada

Air Brake problem

Vehicle breaks on several occasions have randomly locked up. Latest incident occurred 5/2011 in which I was approaching a traffic circle attempted to apply breaks and they began to lock up and make a loud grinding noise and ceased up. After about 4 or 5 seconds the breaks seemed to release. The locking of breaks appears to be the same problem I had in a 2005 Armada that also had bad rotors, of which I was assured when purchasing 2010 Armada was not a issue. To date the breaks have locked 3 times since purchasing vehicle in 7/2010, with months in between occorrances. Luckily I have been able to steer the vehicle out of harms way or the consequences could have been very serious or even fatal. The vehicle was taken to dealership at which time they said and have said in the past that they can't find anything wrong. So there have been no attempted repairs or replacement of anything. I have also contacted Nissan corporate and filed a complaint but they have done nothing since the dealership can't find a problem or duplicate the problem. But as it was with the 2005 Armada, the problem is random and could never be reproduced when I took it in, but yet Nissan knew it was valid problem with the model and came up with a reprogram for the abs. Apparently there have not been enough complaints to warrant a real investigation into this matter from Nissan, they have instead elected to rely soley on what information they have received from dealership. Nissan also suggested I leave my vehicle with dealership for several days. Guess what, I have already done that, for almost a week of which they came up with nothing. Not one day has gone by that I don't think about what could happen when getting into my vehicle. This is no way to live, and perhaps the problem is not prevalent but it is a accident waiting to happen in my SUV, and Nissan is basically doing nothing. Is today the day myself and or family doesn't make it home?.
