We are experiencing intermittent transmission problem with our six month old Infinity G25X. In stop and go traffic or slowing down, the car makes a noise of varying intensity that can startle the driver. The dealer diagnosed the problem as the transmission shifting to first gear improperly. Infinity has admitted they have no fix for it, but claims that the car is performing as designed. All the offered are a couple of free oil changes instead of fixing the problem. The car also hesitates when taking a sharp turn after stopping . Driving this so called upscale car has been an unpleasant and disappointing experience. Instead of its top rating. Has anyone else had such an experience? Consider you options before buying one.
