“All 4 of my windows will not go up or down. This happened within weeks of each other. There is no cheap solution. Kia wants $150 deposit and I was quoted $225 per window. This is insane. I am driving a car where the windows are all wedged up which is a safety hazard. I am not the only one with this problem. Are there any recalls for this?”

“My rear driver's side window started falling down all of a sudden. I had to replace the regulator and the motor. Now, just a few months later, the passenger rear window is doing the same thing. This seems like a defect. I never had to replace a window motor in my 1997 toyota 4runner that I just traded in in july of 2018.”

“My headlights have gone out 3 times in the last four months. I've never encountered this type of problem with any other vehicle. This car is s 2016 Kia Optima and had left me without headlights .I notice others have complained about the same exact problem. This safety issue needs to be investigated . Very dangerous to drive without headlamps. Someone please make note of this serious situation immediately!!!!”

“Sometimes when I start the car it only runs at about 500rpm and the digital speedometer starts going up in numbers when I'm in park and I have no power steering. I can put the car in drive and park or open the door and it starts acting normal. It also acts like it's going to shut off when I come to a stop. I am aware that the rpms drop when you stop almost like a gas saver but with in the last 20 thousand miles it has gotten really rough. …”

“My car stalled while waiting at a stoplight. When going to accelerate I was unable to. However, I looked at the current recalls for my car. The year, model, manufcature date meet the criteria for the axel recall. But my VIN # doesn't show any existing recalls.”
