vibrations at around 80mph?
 

Hey guys, am i the only one that feels vibrations at around 80mph? the steering wheel and navi/touchscreen area vibrates, enough to bother my hands holding onto teh steering wheel. i wonderred if it was only the steering, so i felt other parts of the car, and the navi/touchscreen also vibrated. It vibrates at around +-7 mph around 80, but at more and less than those speeds, the vibrations stop. I tend to cruise at around this range during long highway rides... anyone know why this is happening?

Is your car stock?

Sounds like it could be an alignment issue.

Get your tires balanced

is it a subtle but firm vibration at that speed that intensifies under acceleration/decceleration? is it on every highway? i have the same thing but it is under those conditions and is inconsistent. you can sense a little vibration on a well balanced tire at certain speeds. if the car is really new then take it to the dealer. i am sure they will say it is fine. if it is a big deal then take it to someone who knows wheels and tires.

Assuming the tires aren't flat spotted from a panic stop, check to make sure there is a wheel weight on all 4 wheels. If they used to be in balance and now aren't you may get them re-balanced but it could also mean you found a screw or other foreign object punctured into your tire. There could something worn out or defective in your suspension that should be checked. One thing to consider is that some performance tires tend to get flat spots in them just sitting overnight, and after 5 min of driving they will warm up and ride smooth again.

i only have a boost gauge installed, but i felt it before i put it in, so it is stock. i only got 3k miles on it, and havent driven it HARD much. i do turn fairly hard to see if i ever will feel roll though..haha. so you guys are saying its a wheel/suspension problem? i typically feel it when im not accelerating. when i accel from around 70 to 90, i never feel the vibrations, but if i go from 70 to 80, and then maintain 80, thats when i feel it. i doubt its the overnight problem, because i feel it AFTER around an hour or 2 of driving.

tire balance or....
 

could a tire/wheel weight been knocked off?
