I don't know if any of you have the same problem as me, but I have a 2004 TL 5speedAT with 76,000 milage. I recently went on a road trip with the TL, and as I was driving on the highway I felt the urge to go fast. I was going at 110mph and couldn't go any faster!!! why is that? also after 90mph my steering wheel started viberating. Now I know it shouldn't have anything to do with my tires cause I changed them 6 months ago to Yokohama ADVAN S.4. . Does anyone have an answer to my problem?

 

did it bounce off at 110mph or just not want to go higher? i remember my 04 accord coupe v6 auto did the same at like 110-115mph and id have to let off and get back on it. As for the vibration i would make sure your tires are balanced and that you have a correct alignment.
