Do you have an 04? There's a TSB for the virbration.. My dad had it done on his TL. It doesn't eliminate the problem, but it helps.

I have a 05 TL with a 6 speed MT

 

I traded my 2001 Acura TL for a 2004 Acura TL with 40,000 Miles. I have a vibration and I took it back in. They said they could not find anything at the dealer I purchased it from. I did not find out about the vibration issues until after I purchased it. I still have the vibrations at most speeds. I have Cooper Zeons which were on it when it was purchased. I believe my sales person did a bate and switch. I test drove one car and ended up in another(Same Color and Year) because I wanted a lesser price and payment. I know my fault but I do have a warranty and the main issue here is the vibration issue which I don't like. If it continues than I will end up in a Lexus after over 8 years of owning an Acura brand. Any suggestions other than balancing?

 

I have this drivelive vibration on my 06 TL. The vibrations is the only thing making me hate this car. I brought it to the dealer and they blame it on my wheels and tires, but it is obvious it is from the engine.

Even if they do feel the vibration, they can't do anything because there is no TSB for it except the 04's
