The contact owned a 2007 Kia Optima. The contact stated while driving at 5-10 MPH, the vehicle before her vehicle slowed down suddenly. The contact slammed the brakes and the air bags deployed and deflated. However, the brake pedal hesitated to respond and became soft, causing the contact to crash into the vehicle in front of her. The contact was unsure whether there were warning lights illuminated. The contact stated that it appeared that the air bag deployment overrode the brake system and caused the stopping distance delay. There were no injuries sustained. The vehicle was towed to the contact's residence. The vehicle was totaled. A police report was filed. The dealer and the manufacturer were not notified of the failure. The failure mileage was unknown. The contact stated that what appeared to be a deflated airbag blocked her view of the road in the same moment that she slammed on the brakes. There was a delay in the brakes actually stopping the vehicle so as a result, her vehicle hit the vehicle in front of it. The vehicle is now a total loss. The contact was not aware that the dealer and manufacturer were supposed to be notified of this incident.

I've seen in other forums about engine recalls. I was never notified and the engine in my car disintegrated. It was replaced with an engine from a wrecking yard. This should be covered by manufacturer. I had issues with the brake lines rusting out. This should not have happened either. Not being able to service the transmission and arguing with the dealership about this should be replaced by manufacturer!

Knage123575112607 I took my car in today because of a letter I received for a service campaign. There are all several problems regarding my brakes loss of fluids severe corrosion flaking or scaling of metal brake pipes and I was told the weather has caused that when I called the consumer Kia phone number. I have oil leak from the back of the engine and rogers very very rusty. Both front struts leaking. I took my car back to Kia summit place in waterford Michigan. This is where I bought my car. They told me that all of that corrosion was because I live in Michigan.

I was traveling 25 miles an hour on a road and my brakes locked up at a red light. This happen once before, I thought it was because of the rain. Lucky they car in front of us ran the red light to keep us from hitting them. But on the 8th of this month my sister used my car for her drivers test, she tried to use the emergency brake for her test. The man testing her said it does not work. I do not have the funds to fix this. I feel the dealership I bought it from should fix it or replace the car. This could cause a wreck that could kill our family.

While backing out of a parking space, my car suddenly accelerated while in reverse gear. I put the brakes on but to no avail. I had no control of the speed. This is all happening going in reverse. I crashed into the building next to the parking lot. The floor mat was seated properly and yes my foot was on the brake pedal.
