2004 with approx. 7,200 miles. Rattling noise heard in 1st and 2nd gear. Dealer said it needed new tranny. Replaced tranny. Picked up car and while driving home, could not get it into 5th or 6th gear. Back to dealer. Was told that tranny was bad and had to be replaced again. Picked up car and within a week heard a knocking noise in 5th gear, vibration in stick shift and a clanking noise when applying the brakes for the first time after car sitting for a bit. Later found out that dealer lied about installing the 2nd transmission. Dealer refuses to tell me or give me paper work stating what was done on car the 2nd time they had. Infiniti consumer affairs and regional manager have not proven to be out for consumers interest. In fact, they call lying about the 2nd tranny a "mistake". Sounds like fraud to me, especially when I was told several times that they don't repair trannys . . . They only replace them. They also gave me a work order/paperwork stating that new tranny was installed twice.
