That it is not reliable and that the claimed warranty is not really as stated.
The vehicle is small and efficient but I have had an intermittent problem with the engine/trans that they cannot fix. I have also had the car die with a blow master fuse that was not covered under the "bumper to bumper" warranty as well as a torn seat bolster that I had to repair out of my own pocket. I do not understand a "bumper to bumper" warranty that does not cover things. I would not recommend Hyundai for these reasons.
