Recently reported POWER TRAIN problems on 2008 Infiniti QX56

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. *tr

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. in a panic, i pressed the brake and slowed down enough to force it to "park". i restarted the vehicle several times and it revved to maximum rpms. i left it in the lane and called my wife who called ctv towing. after about 30 minutes i started it and it idled normally so i carefully moved it to the lee lewis road (less traffic and speed). the vehicle was then towed to nappleton infinity in tallahssee, florida on monday. i called the infinity dealer to tell them it was coming. after running computer checks and test driving, they concluding that the accelerator was hung on the floor mat. that is actually not the case as there was an obvious spontaneous acceleration that started in tallahassee. the floor mat was not moved between the time the vehicle accelerated on mack dekle road and the time it idled/ran normally to move it to lee lewis road. *tr
