I had a 6MT 05 TL non Navi; the steering wheel and the car Vibrate once i reach 50MPH above!!~
Bring it to dealer, they told me my rims are bent, but i remember i had the vibration issue since I bough the car, but i was try to tolerate it..
And i cant stand it anymore.. and it also has some echo in the cabin once i reach 50MPH as well.
Now i want to go for lemon lawyer, but i need at least 4 order repairs that stated the problem, and they cant fix it.. Now i am worrying they will push the problems to the rims, but i know you guys has the vibration problem as well,
So please tell me what to do...
Thanks

 

Tell dealer to put on different wheels as experiment - they might be right after all.

 

did vibration happen with brakes applied? if so, disc might be messed...

if not... check tire balance.
