Yesterday I left the parking lot after work and after driving for a few minutes I noticed that the parking brake light was on. The parking brake was in the up position and the car was in drive. I have had issues with lights coming on even if nothing is wrong (tire pressure light). At the time I was traveling at a low rate of speed due to five o'clock traffic. So after getting onto the freeway the speed increased then I noticed when I depressed the brake pedal to slow down the vehicle began to shudder/shake and the brakes didn't seem to be working as they should. It was a noticeable grinding noise as well. So I continued on slowly(35mph) until I reached a point that I could stop. I checked to see if maybe I had leaking brake fluid. I saw nothing coming from under the car. I stopped the car in order to do this. Well once I got back in and started the vehicle the light was off and the brakes were working as if nothing had happened. I am concerned because I see blogs where people have had the same problem as me. What I didn't see was a recall or any acknowledgement that the Armada has a malfunction of some sort with the braking system. I have been reading about anything I can find that identifies the part or problem. So far nothing. . . I will be taking my Armada to the dealership to get a diagnostic just to see what if any code will match my description of the events yesterday. I am worried that I will experience brake failure altogehter.
