I just purchased an IS250 AWD and feel a lot of vibration when driving even on new roads I still feel every bumps very hard. Is this normal? I got a headache when driving 3 hours on the highway today. I thought the car was supposed to be super smooth.

Any help/advice is appreciated.

so you get vibration on highway driving?? if your steering wheel shakes then you need to get your front wheels balance. if your whole car shake then try get all four wheels balance.

let me know if that solve the problem.

The steering wheel doesn't vibrate the car just bounces up and down. It's like I'm in an SUV on a rock path but I'm really in a sedan on a flat highway. I drove around my street in my 1999 323i which was smooth and them compared it to the IS250n AWD and the IS250 is super bumpy like I thought when I drove on te highway -- even at like 15 MPG it tremours through my seat. Any other ideas? Thanks

So how did the car drive for the few miles you drove it before you bought it (because I just know you drove this car to your satisfaction before you paid for it)?

your is250 should have better and sportier suspension compared to your old 323i. if the supsension is stiffer than your 323i then you might feel more bumpier ride.

plus the road, and especially the tires.. you might have to get use to the 17inch wheels compared to 16inch wheels. the ride on that will be different as well.

Sounds like something is wrong with your car. I had an IS250 AWD as a loaner, and it although it transmitted the bumps like a typical sports sedan, it certainly didn't vibrate or tremor through the seat at 15 MPH.

check your tire pressure, they always come way overinflated, dealer lowers it during PDI.

i don't think the tire pressure will do any of this...

go check your rim at local rim shop and ask them if they can spin it for ya.. seems like you might have bent rim(s), cupping tires, or bad shocks..

I suggest you should go back to your dealer and test drive another IS250AWD. You will know if all the other AWD are like that or it's just yours.

I cant really tell because mine is not AWD.

Good luck
