What drive mode? Just curious....

 

[Albert Ruiz]

Comfort mode.

 

[Frankenmoose]

I’ve never encountered the issue. I drive at highway speeds 2 hours a day for work and the only vibration I get is from the LKA.

Did you lower the tire pressure after leaving the dealer?

Did you lower the tire pressure after leaving the dealer?

Yeah good call check tire pressure! May be too low or too high.

 

[plutoridge]

Better to get it checked. Most common reason is related to tires but others could be brake rotors, calipers etc.

 

[Buckeye-TRide]

No. These things are silky smooth. Any vibration you feel should be checked. Anything noteworthy about the pavement you’re on? Is it newly paved or concrete or anything?

 

[Tim-in-CA]

My tires were way over pressurized from the dealer. I’d check them. Look on the door tag for the correct pressure, not on the tire itself.

 

[mrmac]

Most likely have a tire out of balance

No. Have not messed with it.

5&1/2 hr drive to Gulf Coast yesterday. It would Vibrate right at 70 and fade away when you went faster. I will check the tire pressure this morning. I know the tires are filled with N2, if the pressure is low can I just add air or does it have to be N2?

 

[Rondakay]

No. Have not messed with it.

They usually ship with 50psi... You need to bring it way down

Ok. Thanks for that info I will ck that.

No, good Ole air will be fine, it's 78% Nitrogen anyway.

Just ck’d pressure in my tires. They are all at 35psi. I guess when we get back from the Gulf I will be taking it to the Dealership so they can look at it.
It feels like it’s coming from the drivetrain. To me it kind of feels like a very mild drive shaft vibration.
Other than that we luv the way this vehicle rides and handles. Hopefully it will be a quick fix.

Let us know what the issue was.

 

[Albert Ruiz]

Without a doubt

 

[mrmac]

If you feel the shaking in the steering wheel, a front tire is out of balance. If you feel it mostly in your seat, it's a rear tire. There is nothing else that will only cause vibration that changes with speed. Depending on how much weight it is off will determine the amount of vibration.

I noticed it in mine, too. Then today I was taking a customer for a test drive in an SX, they mentioned they could feel a "shimmy". I'm going to take mine out for a good long drive tomorrow, and see if I can narrow it down.
