My 2009, love it, just traded it for a new 2018 Elantra, Had bought a 2017 Sonata for my wife a year ago traded it for a 2015 Elantra. Problems the 2015 Elantra was just not right, driving and confort,The 2009 Sonata loved it,but both Wife and I did not enjoy the steering on the 2017 Sonata:nerd:00000732 still don't, I am now driving the 2017 Sonata. Two day ago I bought the 2018 Elantra, it is amazing, the handing was super, and very enjoy to drive and ride. Question? Is the steering problem with the 17 Sonata pure software, if so would the 18 Elantra software run on the 17 Sonata? Sorry about the errors, had a stroke a few years ago, sometimes the left brain goes a little weird!
