What years? I am very active
Just 2014 and just 250? I am very active on the Facebook IS owners club (6,646 members) and I don't remember anyone ever mentioning it. My IS has never had that problem. I have had the 2014 IS 250 at my house for maybe 10 days total and the 2014 IS 350 AWD over the past year for testing and none ever did that.
