As many, many other have stated on the Nissan forums, this vehicle has some dangerous braking issues. We have had our Armada for about 4 years and have experienced this issue at least nine times. Thankfully for us, it has not happened while we were on the freeway at high speeds or in a situation where we had to stop instantly. Here is an explanation of our issues: while applying the brake pedal we immediately heard a grinding and popping noise, as well as noises indicating that the abs was activating off and on. The pedal was very soft and kicks back multiple times. The braking effectiveness was severely diminished. We have to pull over, turn the vehicle off and on again before we can continue driving. I find this to be a sever issue which is going to get someone killed, if it has not already. More than a few class action law suites have been filed for this issue in the titan truck, Armada and Infiniti qx56 as they all share the same platform and parts.
