We were on the wantagh pkwy as usual then we heard a loud explosion which sounded like the tired had blown. When arriving home we notice the sun roof had exploded and all the glass was inside of the roof. Thank god through our insurance it was fixed and replaced.....we hate to think that it would happen again. If it does Kia need to fix and replace it.

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.

Exiting hwy 71 East bound to woodward decreasing speed the vehicle in front of me had a car cut in front of her. I had a safe distance and slammed my brakes. My brakes did not grab as usual my car did not stop and I hit the vehicle in front of me. I truly believe my brake system failed. I will take my car into Kia when I get it back.

I was driving with my wife at approximately 70 mph on a flat, freshly paved highway with no overpasses or others cars nearby when all of a sudden an extremely loud crash (sounded like a gun shot) occurred right above our heads. All of a sudden the sunshade on the interior roof started flapping around wildly in the wind and hundreds of pieces of shattered glass started raining on my wife and my head and body. The sound and falling glass was so sudden and distracting that I nearly swerved off the road, but luckily was able to maintain control of the car. As my heart beat out of my chest, I quickly pulled over to the side of the highway to calm down and assess what had happened. Upon further inspection it looked like the sunroof had spontaneously exploded outward from the cabin. We have no logical explanation for why it occurred other than that it was a pre-existing manufacturing defect, which sounds consistent with other instances I have read online. Doing some additional research I found that there are apparently hundreds of cases of this occurring in Kia models and a class action lawsuit is being built. Despite all of these instances being reported I was never alerted by Kia that this was an issue or possibility. My car is in the shop now and Kia is investigating whether or not they will cover the repair costs (they better after all we went through). My wife and I both suffered several punctures/splinters on our head, arms, and legs from the tiny glass shards. My wife also received a gash/cut on her palm from a piece of glass. Kia needs to address this very serious issue before it happens to others who may not be as lucky as we were to walk away relatively uninjured.

This started in June 2014 during the mid summer. The trunk would come open while just sitting there or come open while driving. So far no one has been hurt by it opening up while I have been driving but it could come open while I am driving and if I was to travel on the interstate at 70 mph and it was to open it could cause my back window to break or fly off and hit another car causing injuries. Last year during the night we had heavy rain the whole night and when I got up it was still raining hard and I noticed after going out the trunk was open wide. The mat in the trunk was soaking wet, back and front mats and inside where the tire goes had a little one 2 feet of water. I cannot give the dates for all of the time except 4 which was on 10-14-14 where Ford Kia had to remove the water and dry out parts. I was stuck with the bill in which I have the bill and in October 8, 17, 24 November 4,12,19,27. December $10,15.18 22, $24.31. January 2015 2, 8,15,17,18. I have contacted the dealership here about it and I was told there was nothing that could be done and I told them that the people that lived next door had a wireless key that they could open, turn on my lights inside and out and a couple that lived two doors down had a car and when they moved in that he could open his doors and such which would unlock my doors and turn on the lights and open the trunk and they said at the shop that the freq on my car cannot be changed. It seems that I got a car that many of the people can come and try their key and get inside and just push the button and take off. It happens during setting and driving so the speed I cannot state right.

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 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.

Making a call with my bluetooth equipped in the vehicle, looked down to verify connection, by the time I looked up I was a foot away from a parked vehicle, I swerved as to the left as much as I could but it was too late, I slammed into the vehicle causing damage, my hood and engine were practically crushed in and along the passenger side of my vehicle, my car came to a hault before jumping over the median. None of airbags deployed. I was going speed of 50-60 miles per hour.

I was driving on highway during rush hour when I heard a loud explosion and sound of glass rattling. At first I though I had a blowout on one of my tires, so I manage to pull over to the emergency lane. I then did a walk around of my car and saw the busted sunroof. 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. There was a hole the size of a basketball in the middle of 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.
