This is troublesome news because as the following article states Nissan began offering a 'fix' for the brake issue to dealers in 2005 and I would have hoped it would have found it's way into production by 2006. Here's the info I have so far:
Armada’s, Titan’s and QX56’s
Brake rotor “warping” along with premature brake pad wear lead to what is known as “brake judder” or “steering shake”. This is caused by the pads “riding” up and down on the warped rotors – transmitting this into steering wheel “judder” or “shake”. Severely warped rotors will cause the vehicle to shake so violently that the driver’s ability to hold onto the wheel and steer safely can be substantially impaired.
The “OEM” (original equipment manufacturer) parts used in factory production of the 2004 (and some 2005) year-model Armada’s, Titan’s, and QX56’s were found to have one or more of the following customer complaints:
Steering wheel shake upon braking
Vibration in the foot pedal upon braking
Excessive noise/squeal/grinding sound upon braking
Premature brake pad wear
Premature “grooving” and/or “warping” of the brake rotors.
The manufacturer released a “TSB” (Technical Service Bulletin) outlining a “fix” for what they called a “brake judder” condition in calendar year 2004. The “fix” was comprised of some new parts and various procedures. Not withstanding this “fix”, many owners continued to complain that the brake problem continued.
About May of 2005, authorized dealers starting receiving parts for yet another “TSB” to “fix” the problem with the brakes. The “newest” brake kit (and accompanying TSB) was meant to be a permanent “fix” for the brake problem. We do not yet know the long-term effect of this newest “fix” (TSB).
A consumer can evaluate whether their Armada, Titan, or QX56 has the newest brake parts by a very easy review of the dealers most recent repair invoice(s). Look for the part numbers which will be listed below the repair work performed. The newest parts will contain the letter “z” within the part number on the brake pads, and also the rotors (brake discs).
