Been having issues with the driver side window for some time. When pushing the window up, it keeps going back down. After mentioning it to the kia dealer they said there was nothing wrong. Well, just yesterday the entire window made a cracking sound while trying to roll it up while driving. Then the entire window just fell all the way down and now it won't go up at all while driving on the freeway. Not sure if it came off the tracks or if it has something to do with the motor. After doing some research I have noticed that a lot of kia owners have or had that same issue. This is definitely some kind of defect/problem if so many have the same issue and it should be recalled since it seems like a problem with the manufacturer.
I was driving on the freeway in the state of utah. I was going 65 mph on the freeway when the car started shaking, followed by a stall on the engine that forced me to slow down and park on the side of the freeway. I have no idea what happened but I heard cracking noise coming from the engine. Now the car won't turn on.
I was on I-40 going about 75 mpg. Temp was about 75 and the driver side window cracked a little. 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. Nothing flew in my car. Nothing flew out of my 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.
