I was driving on the freeway at about 70mph when my panoramic sunroof suddenly exploded. It was not hit by a rock or any sort of debris, it exploded completely on its own without warning. The loud explosion caused me to swerve and panic brake as glass shards rained down on me from the broken sunroof.

I have sent in complaints on my kia many of times and the one just came out about the latches, mine is not on the recall list. I have had the middle part of my glass crack the windshield that was and still under warranty and more but it seems I am being over looked on my car. I guess the only action to take is a class action lawsuit against kia america. When you have the proof they still do not believe you.

I called the police to get a report but the officer said it had not been hit from the out side and take it to kia. I took it there and I was told I was hit by something like a rock or ball. The man at kia said take it to my insurance company. I took it there and the agent said it was hit but I had to pay $100.00 Before it could be fixed. A...

man from the glass repair came to look at it and he said it has been broken from the inside and he could tell better when the old one has been removed. He came out on 5/3/16 to replace it and he said that whoever told me that window was broken on the outside did not know what they were talking about. After looking at it very close he said that what broke it and made the cracks was the laminated plastic that holds the two pieces of glass together and it was a defect in the glass. Kia always tells me when I have a problem, that in no way the problems was from kia's making the car. This is my third problem with that car that they tell me they either cannot find the problem like with the trunk opening up, the battery they replaced on me by taking out almost a new one and replacing it with a older one. Now I had to pay out of pocket $100.00 When it was no ones fault about the glass but kia because I still have seven months warranty left on the glass and they did not want to have to install a new one so they could save money and time and keep people thinking that kia is number 1. This kia with under 19,000 miles is junk to me and with some recalls on the make, model and year of this one, not but one single recall was ever made but you did not have to have it done. On this and other kia's they should make kia america rebuy all those cars.

The shade was not down on the sunroof, but the sunroof was not lifted.I was about to pass a vehicle to my right. All of a sudden there was a loud bang in the back of my head. I was so thrown off, I almost let go of the wheel. It echoed in my head. I panicked and pulled over on the interstate and flagged down a state trooper. The trooper checked... My car was not hot.

car. There was no other damage besides the hole in the sunroof. But you could tell that the explosion came from inside the car. The trooper was speechless. I was terrified to drive the car anymore because I didn't know what caused it. We concluded that it had to be some kind of air pressure that caused it. Again, I'm not an expert but I do know that I didn't do anything to cause this. I keep my car in great condition. After seeing the other reports, I'm glad I heard about this site. Please mandate a recall or rebate for people who have had this issue. The is extremely dangerous. My hearing in my right ear was "fuzzy" for a few hours, I had a massive headache, my ear is sore, the whole right side of my body hurts. Thank god I didn't have any cuts or bruises, but it felt like it (weird). I could have caused a horrible accident if I took both hands off of the wheel. And it's sad that kia has not addressed this with so many complains. We shouldn't have to pay a deductible for a manufacture flaw. *Tr

Driving down the freeway at 70 mph, sunny clear weather, temp 85. No overpasses or other vehicles in sight. The sunroof exploded showering an enormous amount of glass on top of my head resulting in a few minor cuts. Either I was struck by a meteorite or kia has defective glass. The dealer replaced it for $550.00 And no explanation. As there are several other posts with similar descriptions I feel kia has defective glass and this should be investigated.. I very nearly lost control of my car at freeway speeds. *Tr

velosters, and other car manufacturers. My car is at the dealer now, and kia is aware of the issue and is investigating. Luckily I remained calm and pulled over to the side of the highway to clear off the glass and go to the dealer. That sound and shower of glass could have easily startled someone else and possibly caused an accident. I do have a picture of the sunroof prior to breaking away the additional, broken glass. Please contact me for it, should it be needed.

I was driving on highway during rush hour when I heard a loud explosion and sound of glass rattling.

There was nothing overhead nor did I see any flying rocks or debris at the time of the explosion. There was nothing other than the explosion. The glass was bubbled up like it blewout and not in.

the sunroof. There were no rocks or anything inside the flap between the glass and interior. Also the flap cover is very thin and flimsy, if something had fallen on it, it would have hit me on the head because it is just a thin material cover. Furthermore, it was a sunny day, at roughly 73 degrees. All I can say is for a sunroof to explode outwards, the glass has to be defective in some sort of way. It scare the living lights out of me, it was such a loud explosion. If I had the cover undone, I would have been hurt by the broken flying glass. I took it to the dealer and the manager there took pictures and then made a comment that he would forward the pictures to the dealer but that it would be denied because the last kia that came in with the same problem the dealership claims person he was planning on forwarding the pictures to had denied the claim and it looked the same! This shows me that kia is very aware that their product (sunroof) is defective and has a potential to explode but of course they will not claim their product has any defects because it would cost them too much. I am not the only one with this incident obviously. I need for you to begin an investigation into trying to determine if the glass is not tempered enough to withstand certain temperatures or if there are other defects that cause it to explode. *Tr
