A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Dt*: the contact stated while driving 50 MPH there was a thumping noise as if the vehicle had a flat tire. The dealership determined that four of the six bolts on the left rear axle had sheered off and the bolts needed to be replaced. The manufacturer has not been alerted.
I have a 2006 infiniti qx56 since purchace I have had the speedometer cluster GPS and fuel sending unit relaced also vehicle has been at dealer several times for suspension problems . When driving during accelaration car has vibration, if you hit a bump this vehicle will bounce like a ball sometimes bottom out. When towing if you hit a bump this vehicle will change lanes.
Brake failure on 2006 infiniti qx56. One time. Situation dangerous, driver avoiding pedestrians and vehicles on a busy thoroughfare.
Multiple/numerous incidents: while at both high speeds (highway) and local driving the dashboard flicker and the ABS light comes on followed by loss of braking, groaning/grinding noise and inability to control the vehicle speed. This has occurred numerous (>20) times and the only resolution is to pull over, stop the vehicle and then restart the ignition to reset the braking system. In addition, we have lost brakes twice that resulted in the vehicle travelling through a red light at a 4 way intersection.
The brakes get hard and cannot stop quickly. It grinds and have to park and cut the engine off for a few minutes then it works again. Almost caused a fatal accident. This is definitely a factory defect due to lots of owners on the net having the exact same problem. There is no indication when it about to happen. It happened at least three times since buying this vehicle used for my wife. This problem happens also with the nissan armada. Contacted the manufacturer and they don't seem concerned at all.
