Failure Date: 11/19/2019

As I was driving on the interstate 3 vehicles passed waving frantically before speeding by. I noticed a reflective orange flicker along the base each vehicle. This was followed up by a loud knocking sound before I lost all accelerating power but retained rpm revs as I pressed the pedal. I allowed the momentum to get me as far up the exit ramp as possible prior to pulling over onto the grass. I placed the car in park and turned it off to be met with an instant roll of smoke up the front windshield, out of the front grill, and from the passenger side tire area. I exited the vehicle to the sound of liquid hitting a hot surface and hissing. I stepped away from the vehicle and looked underneath to be met with rolls of fire dripping to the ground from beneath the engine and along the bottom center of the undercarriage of the car. I immediately cleared the area and my vehicle was complete engulfed in flames in less than 4 minutes. No sensors or alarms notified me of any type of malfunction.

38 Other Fuel System problem

Failure Date: 10/01/2019

When taking off at a stop light or getting onto the interstate (basically when accelerating) the car feels like it has no power. You can hear a weird noise and sometimes you will smell burnt oil or something burnt. Also, I had a recent oil change and within the month I had to add oil again. There is no sign on my driveway that there is a leak. Please look into this as there are multiple people with the same issues.

39 Other Fuel System problem

Failure Date: 05/01/2019

I had just reached my destination. After being parked for approximately 30 - 45 minutes when I tried to crank up to leave. I put it in the drive gear and it would not move forward or backward when put in the reverse gear; then I had it towed. Then when attempted to crank it; it caught a fire and destroyed all of the motor, and most of the car before the fire could be extinguished.

41 Other Fuel System problem

Failure Date: 03/22/2018

My 2015 kia Optima with 46,000 miles started smoking and running roughly; I brought it to the dealership where the service manager then gunned the engine very hard until the engine seized up. Later they told me the engine needed replacement for 7k and they would not cover it because I did not get oil changes with them. I told them I change my own oil or get it done at a local place in town because I don't feel like waiting for 3-4 hours for oil changes at the kia in glendale CA where btw the service is terrible. This engine should be recalled like the others; it is not a production defect it is an engineering defect and the sooner kia recognizes that the less liability they will be responsible for. This company is a real disappointment and I hope they will move to a voluntary recall and not put all their customers through hell waiting for the government to force them. I speak nothing but negatively about these cars so other people won't be in the position I am in.

42 Other Fuel System problem

Failure Date: 03/08/2018

The following happens anytime while driving the electronic control unit and software, sensors, actuators, warning lights, fault codes, and performance related concerns of the electronic stability control system. My passenger window won't go up once you put it down without a fight. I been to the dealer 4 times and it's not fixed.
