So I'm taking my car to the dealer tomorrow. I'm going to have them check out the normal culprits for this. Warped rotors, unbalanced tires and even have them check the two older tires. On AWD cars you are suppose to replace all 4 at one time, not two and then two later. Although I don't think it's any of the above. The car vibrates when under power, as son as you let up on the gas it goes away. This is under normal cruising speed and even under acceleration. Is this something these TL's are known for and of so what is it? I have never had a car do this, the vibration is felt through the steering wheel and pedals.

 

Sounds like the torque converter. They have a recall on them. Ask the dealer if it's been done yet on your car.

 

Sounds good to me, thanks for the info.
