I sold my beautiful 06 M45 sport last month to save some $$$ on gas. Ended up Settling for the IS250 with all the toys of the M. I have to admit now that I'm very impressed with the 250. My full tank provided 446 miles today. I was averaging 28 miles in City and 32 on the Hwy. As I am approaching 5K miles in only 1 month, I noticed the better the driving. Pick up is very zippy for not being a 350. The only problem I noticed is the wobbling at high speed. Anyone experience this?

 

what kind of wobbling?

 

you drove 446 miles in a day??? wow man. and i thought i whipped through oil changes...

 

It appears that the steering wheel is very sensitive. The car does not gravitate to the road above 80. Perhaps I am used to driving the Infiniti and the NSX which handles very well.

 

i didn't notice any wobbling when i'm driving near that speed. i've been around 115-120 and no wobbling.

i usually don't speed, but i can't resist the urge when there is a wide open road in front of me.

 

no no... the car isnt wobbling... your experencing is the 'floating' feel of the steering wheel when going straight... just go on any straight road and try to hold the car, i think they did this cuz its mostly old ppl who buy lexus and they usually have the hand shakes

 

446? i dont believe. it better be all highway miles or i call bs

 

LOL!


It sounds like something is wrong! I've taken my car to 135 and it felt very solid. Either it was a very windy day or you have bent wheels, or need an alignment or something of that nature...I would check with the dealer it would probably be covered under warrenty

 

Okay I was a bit over exagerating... it was 445.

 

wobbling? never yet and hope not. might want to get an alignment or ur tires rebalanced. took her over 100mph nothing but smooth driving.

 

If I remember correctly, 1st oil change is at 5K right?
I'll just have the techs look at the items you guys noted.

Thanks for the input.

 

damn i hardly ever get 300 and you get 445 seems like a lot unless you modified your gas tank

 

I think it's the tires?

 

Rear wheel drive cars are designed to be stable at high speed. It doesn't matter if I have the OEM wheels or my 19's on my IS350 and it doesn't wobble a bit at over 100mph, I think it's even more stable at higher speed. There must be something wrong with your car, you should have it checked up.

 

something is definately wrong. generally while driving on the highway i cruising around 90-95 and the car rides just as quiet as if i were going 60. and the car is planted firmly with little give.
