2010 Lexus GS350 Wandering/Pulling on the Highway
Hey Guys,
I have a 2010 Lexus GS350 RWD. It has around 5,000 Miles.
It is wandering quite a bit and constant steering corrections are needed to
keep the car strait. I took it to my Local dealer and went with the tech on
a test drive and they replaced the tires (Yokohama Advan 18") with (Bridgestone Potenza 18"). They did a 4 Wheel Allignment and Balance. The problem is still there but the Noise from the Yokohamas are gone. What could be the possible problem? I have a appointment on Tuesday With the Assistant Service Manager on Tuesday to figure out the problem.

Nope. Dealer Checked everything before they issued replacement for the New
Tires. Also looking at a Edmunds review it looks to be a common problem
Copy and paste from Edmunds:
Have complained about wandering at highway speeds. Car requires continuous steering corrections. Factory rep checked, realigned and dealer has changed tire brands. Still the same. I don't trust Lexus (aka Toyota) to admit any problem especially since factory rep says he has never heard of any probs like this. He admitted he never reads Lexus sites. Relationship between electric steering, wheel/tire and suspension doesn't seem to be near as precise as my mbz clk500 but this car is as my wife describes: "jittery." I don't Dare take my eyes of the road for a second. I might end up three feet into another lane or shoulder of the road. Have 7,500 miles on odo.

I have a 2010 Lexus GS450h also and have no problems. It seems that their are only complaints on the GS350. Not the GS460 or GS450h

One is the shocks are different on the GS350. Maybe if you replaced those the car might be more stable.
The other is that the GS is a heavy car. Soft sidewall can cause some wobble, particularly when you have an uneven surface. It can cause asymmetric sidewall flex which results in the perception that the car is unstable. Stiffer sidewall tires can eliminate this. E.g. If you buy a performance tire with an XL load factor. Of course it does reduce ride quality.

I can only think of 2 things.

MY GS450h has the Dunlop Run Flat Tires on it which i have no problem with other than the bumpy ride. I will see what the Service Manager wants to do. I just test drove a Brand New GS350 over at Sewell lexus and it had no problems.

Ruyn-flats eliminate the tire-wall flex issue. However low-quality run-flats can be susceptible to other issues. What can happen with run-flats is the following:
A run-flat tire in simplistic terms is is essentially 2 hard disks with a rubber wrapper between the 2 hard disks. If you are driving on a surface with grooves - e.g. concrete roads, the run-flat disks can slip into a groove and start to tramline with the grooves instead of following the steering direction. This typically only occurs on concrete surfaces and not on tarmac since tarmac is smoother.
I had this problem on I-95 with my original Bridgestone EL42 tires. The car felt unstable when it caught one of these grooves. It didn't occur with the Michelin PS2 run-flats (high quality run-flats like your Dunlops), and the problem disappeared completely with the regular PS2 tires that I have now.
Just another possibility.
Another idea is the alignment. I've noticed the Lexus alignment people are very poor. I hear all the time about cars pulling left or right after an alignment. When I had my tires changed at Lexus of North Miami (a rubbish service dept) they could not after 2 attempts line the steering wheel to be on center!
Next week I'm taking it to an alignment specialist to make sure it's perfect! This guy:

Do you know if the new car you drove at Sewell also had run-flats?
