“On 9-4-2011 I left tallahassee, florida. As I got to the edge of town I noticed it started to idle slightly high. By the time I got to thomasville, georgia, it would accelerate to about 45 MPH without any acceleration pressure and the brakes were required frequently. Between thomasville and moultrie, georgia, it would accelerate independently but it would drop down if I pressed and released the accelerator. It also seemed to maintain speed a bit better if I used the cruise control. As I turned onto mack dekle road just south of moultrie, the engine tacked out into the (maximum) red area. …”
NHTSA complaint #10434839, filed 2011-11, 110,000 miles“My question is somewhat irrelevant now, seeing that the damage to my vehicles is already done. I have owned two vehicles made by nissan, a 2004 armada le and now a 2008 Infiniti QX56. On both of these units the front differential pinion seal leaked causing damage to the front differential bearings. I have heard of many others experiencing this same problem. Q. Can you please tell me why this issue has not been recalled by nissan? It's obvious this is a major problem (among many others with this vehicle) that nissan chooses to ignore.”
NHTSA complaint #10588769, filed 2014-05“The contact owns a 2008 infinity QX56.

The vehicle was repaired but no information was provided to the contact. The manufacturer was not notified. The VIN was not available. The failure mileage was 70,000.”
