Just picked up '14 350 f-sport and I notice a lot of road noise after 100 miles, have about 150 miles on it now and it sounds like the front wheel bearings or maybe the tires? sounds like a rumbling coming from the front. I don't recall hearing it on the test ride, not sure if its normal or not. any feedback would be appreciated. Thanks

 

First, congrats and welcome to CL.

Unfortunately, the sound you describe is not normal. Did you check underneath the car/wheels if something got stuck or is loose? Also if you have a video that would help.

 

How long was the car on the lot for? If it was sitting, the tires may have a 'Flat Spot' which is very commo and gives the driver a sense of a constant 'bump' feeling. Drive the car and over time it should get better (assuming its this)

 

i am having a similar issue with my '09 350 w/58k. not sure if its the tires or wheel bearings making the noise. running bridgestone turanza's el400s front and re050s rear. fronts are 85% and rears at 25%. life. no rumbling, just road noise..

 

No its not flat spots because its not bumpy, just loud. I think it might be the Bridgestone Turanzas are just a loud tire maybe. But for a brand new lexus the tires should not be making this much noise.
