I've purchased the 2004 TL on October 2003. Since the very beginning, the car would constantly vibrate at higher speeds (primarily at 55+mph). Took the car to the dealer for wheel alignment and balancing. The problem didn't go away. Six months later, Acura replaced my bridgstone tires with a new re-fromulated tires. As a result, the vibration felt at higher speeds weren't as severe (though still present). After driving for a month, the same level of vibrations at higher speeds returned. I've been attempting to resolve the issue with my dealer and Acura for 8 months now, but as of today, no resolution has been forthcoming. Vibrations felt at 55+mph, is a serious safety issue and I believe Acura should be more proactive in resolving this matter.
