While driving, the sunroof randomly exploded!!! It sounded like a gunshot and there was a huge hole in the sunroof which continued to shatter glass on the inside and out of the vehicle causing scratches on the paint as well. Luckily there was no crash but it was so frightening with glass all over the inside. I cannot believe that Hyundai knew of this problem and did not address it! We have been very happy with our 3 hyundais that we have had but this 2013 Elantra has had a ton of problems and still only 45,000 miles on it!! Hope they stand by their vehicle and fix it to do the right thing.
