2006 ACURA TL User Comment / Complaint

2006 acura tl a vibration occurs primarily between the speeds of 48-58 mph. the vibration is felt in the floor, seat, and steering wheel. it is most noticeable when the car is cold (after about 3-4 hours after running). it seems to go away after the car warms up. it does not appear to be tire related. i have talked to a number of tl owners and they have the same problem. acura states it is a characteristic of the car and is within specifications. however, acura has not provided what the specifications are, how they are measured, and what my measurements are. the dealer sales manager stated to me that "yeah, acura has a problem there". i did not notice it right away after i bought the car thinking i was on a bad road or the tire was out of balance. it is not at all speeds and not at all times. it is an irritating vibration. i asked the dealer to fix it or buy the car back but they have done nothing to correct the problem stating it is characteristic of the car.
