Pop up wind screen located at front of panoramic roof became rusted through. For some reason the engineers chose ferrous material that is constantly exposed to moisture and high humidity at all times. This is extremely dangerous, as the windscreen is subject to very high stress at highway speeds. This corrosion can cause the part to fail and intruded upon the cabin of the vehicle injuring occupants

While traveling on an interstate - during a rain storm - traveling around 65-70mph - and other vehicles in front of, beside, and behind me - out of nowhere (not big bumps being hit ) there was a sudden boom which sounded like a shotgun going off. This was very alarming and scared the daylights out of me. Luckily I was able to gain composure to notice that my sunroof had exploded as glass continued to come down into the car. I was able to pull over (still in pouring rain) and eventually make it to a bridge where I could shield the rain to see what happened. Once out of the car, it was evident that the sliding sunroof of my panoramic roof had exploded upward. I awaited a tow truck to tow the vehicle to closest dealer (an hour away - in the pouring rain which soaked the interior.) I knew that it had to be some type of defect since the explosion went upward. Upon researching the internet, it appears that this type of defect has happened as far back as 2010. Kia is looking to replace the sunroof under warranty which is probably the same defective sunroof. I do not have any confidence in this car and would not allow my family to be in this car moving forward. It is such an alarming situation and could happen so spontaneously, it is only a matter of time until more devastating accidents could occur. After this experience, I am lucky that it was me driving - not my wife or my kids. It would have been a totally different outcome. Other manufactures have addressed their issue with panoramic roofs, but Kia continues to deny they have a problem. Kia should buy back these cars as they are a safety hazard for not only those in the car, but for any motorist around them. These vehicles should be recalled, and if they continue to sell vehicles with this characteristic, they should have to provide a disclaimer to warn buyers.

I was driving on the hwy and my sunroof spontaneously shattered. I do not think a rock hit it but if it did it should not have shattered. I was told by the dealer that it had happened before but when I arrived to the dealership he then looked and the sunroof and said that it looked as if it had been struck by a rock and that they would have to do an investigation. I then told him that if a rock hit it, it still should not have busted and shattered the way it did. He said it has something to so with cabin pressure. So then if that is the case every time a rock hits it then it will bust and shatter?
