1 Engine Knocking Noise problem of the 2013 Kia Motor RIO

Failure Date: 05/20/2017

I was driving on the highway at 70mph with one other person in the vehicle, when there was a combination of whirring, clicking, and banging sounds from the engine. As we pulled off on the exit it sounded as if parts were falling out from under the car, but when we looked in the rear view mirror there was no debris on the road. When we pulled into the rest area and parked the car to check it out and begin the process of getting a tow truck before the car had us stranded and broke down, smoke began omitting from the hood and it got thicker and flames began coming out from under the hood mainly on the left side of the car until it had spread to both sides and began traveling into the cabin of the car. Car was in good shape, with only a need for an oil change when the problem and fire began. Fire crews arrived and put out the fire. Engine light did turn on and and start blinking as we got on the exit ramp. Car was turned off at the time the smoke and fire began. Most of the damage sustained was on the drives side of the cabin and all of the front of the car and engine area. While we understand this could be something unrelated to a manufacturer default, we want to be sure that we take the correct steps since a car that was only 3 years old did burst into flames.

2 Engine Knocking Noise problem of the 2011 Kia Motor RIO

Failure Date: 07/01/2014

I'm really not sure what's wrong with it bit this is way happened. I was driving to workfrom lunch wasn't having any problems then all of a sudden the engine light stayed flashing. In the 4 mins that followed my car started loosing power so I pulled over to a gas station once I stopped the car I heard a knocking sounds and then the car shut off. There was oil, it wasn't black, it did not have white spots and there was no smoke v of any color coming from the hood or tailpipe. What was weird was that the antifreeze reservoir was completely bone dry. I had a oil change and fluids check and topped off the two months before and had checked the fluids myself the month before after my spark plugs were change. Needless to say finding no antifreeze in the reservoir was a little bit confusing. Had 3 mechanics look at it and they all said if the ass no oil they would have said the rod was thrown or piston broken but I need to pay someone to take the top off the engine to even get to where people guessing the problem is. Worse thing is the car is only 3 years old and maintenance is done on it so why I'm I having engine problems?.
