I drive a 2018 Elantra Limited Edition. When the dealer was showing me how everything worked, he showed me how to set the steering (normal, sport, etc). It was in normal but somehow I think I have changed it to sport because at high speeds, the steering wheel seems to have a mind of its own. Need to know how to re-set this to normal. My Elantra has the ultimate package and I am wondering if it could be Lane Keep Assist that is turned on? Thanks!
