Driving 2004 Nissan Armada SE off road traveling at low speed (20 mph or less) in traffic. Brake light comes on in the dashboard, brake pressure goes to near nothing (have to push pedal all the way to floor to stop car) and brakes make a grinding noise under the steering column. Car stops eventually but no confidence car would stop suddenly. Problem is fixed temporarily if car is turned off and restarted. Happens intermittently could go 3-4 weeks without a problem, but everytime seems to be at low speed in traffic with repetitive use of the brakes. Nissan dealer can't replicate problem and can't diagnose problem without seeing car with brake failure indicator still on. They are recommending potentially replacing ABS computer $1,500 but no guarantee that will fix problem.

We have experienced problems with the ABS system on our 2004 Nissan Armada since early 2006. Periodically while driving the brake light will illuminate, when brakes are applied the ABS system activates and the brakes are very spongy. When released it sounds as though a big spring is released. Each time (approx 8 previously) we've driven very slow to a safe location, turned the vehicle off and back which resets the system. The occurrence happens at various speeds from 25-70 mph. On one occasion I was able to take the vehicle to the dealership during malfunction. Although observed, the weekend technician failed to properly relay the situation to the regular technician resulting in no action taken. Each time we were assured if normal brakes failed, would still have brakes with ABS. The system also malfunctions on initial start up, when turned off and restarted the system is reset. Most recent occurrence was 5/11/2007, I contacted my current dealership and scheduled an appointment. On 5/14/2007, they found the dtc C1179 delta sensor out of program, it was reprogrammed under ntb06-040 program. Malfunction occurred again during initial startup of vehicle on 5/19/2007, taking vehicle back for service.
