I'll get it checked out at the 1k mile service, but curious to know if anyone's stock IS sways slightly from left to right and vice versa noticeable at higher speeds ( above 40 mph).

Never had this with my past '14 IS. Possibly an alignment issue? Any comments? Thanks!

 

Could be steering assist and the LKA? <-- these work when traveling 32mph +

Knowing you got the 17 IS, the LSS is standard on it.

 

Thanks. I thought of that and tried the different Sway settings and felt no difference.

 

Car is trying to stay in its lane. Disable the system and check.

 

It could be the camber of the road. I've noticed that my IS is sensitive to road camber. Depending on how the road is banked (even if it's slight) my car might pull left or right. It's very rare to find a road that isn't banked at all.

 

This. The car is super sensitive to the road. Roads in Toronto are very choppy because of our weather, so I notice it a lot.
On a freshly paved road this does not happen at all.

Maybe putting it into sport/sport+ to tighten the steering wheel would stop this?

 

i'm still getting used to the way it tracks on the road. definitely different from the vette i'm coming from.

 

Got rid of the Audi already I see...
