I was driving on the highway on my way to work when my sonata started making a strange noise. I pulled over to the side of the highway, turned off the car, and tried to restart it. It would not restart and the temperature gauge went up. There was no indication that there was an issue with the car (warning lights or other noises) prior to this incident. I was stuck on the side of a busy highway for 1. 5 hours waiting for a tow to the dealer. The engine seized and needs to be replaced. Now Hyundai isn't honoring their warranty and saying its neglect, getting a second opinion.
