Have a new 2012 QX56 with every option available... Since the Feb 2012 purchase, i feel a vibration from the gas pedal to my foot each time i accelerate from a stopped position. Once i get up to speed it goes away. Service dept replaced pedal assembly under warranty, that did nothing to improve the problem. They said they don'have a fix unless Infiniti issues a TSB... But they "have noticed it in other new QX 56's"! Anyone else noticed this issue? Very annoying to say the least!
