I have a 2011 is250 f sport and for some reason I can't go pass 75 MPH I've taken it to 3 different shops and the don't know what the problem is any help would be great

 

Best thing to do is plug in computer scan codes look them up or take it to a Lexus dealership pay them hour diagnostic fee hopefully that’s all they need to figure it out .

 

Wrong section of the forum, but as someone else commented, more info would be helpful.

Does it have any malfunction indicator lamps on the dash? Any error messages on the display? Does it drive OK otherwise? Meaning full power all other times?

Going to go out on a crazy limb here...factory wheels and tires on it?

 

If you come back, we need more info @Jayon22

 

I'm confused. His previous post was moved to the ISF forum (or he was given a link to the ISF forum, can't remember) but he has a 2nd Gen IS250
