On August 17, my new Elantra lost power steering, and most safety related features. Most all instrument warning lights came on. Was able to get car to dealer service where they kept car overnight, and reset the error lights. They told me, they recorded the computer codes, but could not find the cause of the problem. On August 26, again the instrument warning lights suddenly came on again. Took car to dealer service, where they kept car almost 2 weeks, but could not find the cause. They recorded computer codes.
