Short story. We got this big Nor'Easter two days in NYC, I drove my 19UX250H to work yesterday, and parked a unplowed side street with about 5in of snow. Outside temperature is about 20F. When I drove home last night, the car start vibrating when I hit 50Mph. I pull into a gas station, and check all the tires, no nail or any damage. Tire pressure 34 on four. There's no ice or snow on break or suspension. I parked my car indoor overnight. This morning, the vibration problem went away. I drive all the way up to 80mph, no vibration.

I suspect it's run flat tires that cause the problem. This is my first run flat vehicle. Is this normal?

 

Hi, I have a 2019 F Sport and I have non stop vibration on the gas pedal, steering and seat. I am in Miami so is always hot. The car has been back at different dealers a total of 11 times. Last time a Lexus field tech checked it and agree the vibration was terrible BUT "normal behavior" and refused to do anything else for me.

I already hired a lawyer and started the lemon law case.

Good luck!

 

It turns out my vibration problem was related to low air pressure in the tires. After I parked my car outside in the low 20F, the actual pressure in my tires drop to 27psi, even the dashboard shows them at 30psi. The TPMS sensors do not show the correct pressure in the tire. I suspect this is creating a flat spot on the runflat. I filled all my tires to 36psi using tire pressure gauge, just for the cold weather. No problem for the last few days.

I feel you pain, bro. No one should spend 40k, and get a vehicle that's problematic from day one. Have you try to switch the front tires to the back? If that change the vibration, you will know it's from the tires right the way.

 

You may have had ice/snow built up inside the wheels which caused them to be out of balance until it melted. I've had this happen on many cars often.

 

Glad your issue is fixed.
So yeah I have been to 5 different dealers already and as I mentioned Lexus sent his own corporate tech and he agreed issue was there BUT nothing they can do.
Funny thing is I traded a BMW with 0 issues for this lol! Reason I traded was because it was high on Mileage and out of warranty so I did not want any unexpected repair costs and since Lexus has so good reputation I gave it a shoot.

Boy was I wrong! lol!

Never again, as soon I win or lose this Lemon Law case I wont ever in my life buy another Lexus. I understand Lexus have good reputation BUT the way corporate has handle my issue is a disgrace! Telling me in my face yes we agree, the car is a nightmare to drive ( their own words ) BUT is a normal behavior and we have no fix..... Yep sure. See you in court.
