    On September 27, 2023 I was driving home at 50 mph on 41st & Lynn Lane in Tulsa, Broken Arrow, OK. The car just shut down right before I had to stop at a stop sign. Not being mechanical minded the only thing I could think of was to call a towing company (AAA). I was informed to also call 911 to have a police officer come and block traffic to keep me from getting hit. It was towed to the only garage there is close to my house as the Ferguson Dealership couldn't take it at the time. It was at a place called The Garage. They at the time told me they thought it was the fuel pump and replaced it. The work was done on October 2, 2023. On November 26, 2023 I was driving home on the Cimarron Turnpike when the car just lost power. I pulled over as best I could and did after a bit get it to start again. I called my brother to see if he would follow me home as the car jerked and would only do 60 mph. I put on my flashers and my brother did follow me home. I have researched the trouble and saw a recall #147 (Kia's # I believe. it is a recall for the engine and something to do with the KSDS. Kia Dealership ( Ferguson Kia) again couldn't take the car so I took it to The Garage again and received a call from the tech that I need another motor. I am calling Kia Corp to see if they will replace it.

The carbon build up is known in every kia engine as everyone knows they came out the factory with defects. With the exhaust valve burnt it scored the cylinder and none of it is covered under the extended warranty and I have seen many people with the same problem and all the dealership does is grind off the burnt oil on the exhaust valve and return it to the costumer while it is a ticking bomb. It is known to the dealership that this is a defect in the engine and which they told me on the phone while all calls are recorded. There was no sign that this was going to happened to the car.

  11. Engine, Jun 5, 2023

    We have tried numerous times to get Vanguard Kia in Arlington, TX to address the recall on the engine. They have only updated a short term fix which is a software update. It will be 2 years in October that we have been trying to get the recalled engine replaced. They updated in their system that they replaced the engine but the same old engine still remains in the vehicle. They have charged us for many other repair issues and now tell us they don’t know what is wrong with the vehicle and can offer no solutions. We have repeatedly asked for them to correct their error and they refuse. I believe individuals working for the dealership may have fraudulently reported addressing the recall engine and may have kept it. We have reached out to Kia and have not heard a response. Is this legal?

  12. Engine, Jun 3, 2023

    I tried to speak with Kia about a recall the engine on my making model I remember seeing it on your guises website this issue was never fixed and I’m currently having issues with my engine and they’re refusing to replace it. I’m trying to avoid a lawsuit and a serious accident because of the way my car is acting up. It is accumulating me a check engine, light, as well as a oil light I’ve brought the car in many times to vanguard kia and they could not figure out what was wrong with the car , and holding it for week the two times i brought it in and it seems as if you’re continuing to drive it is creating more issues because I had to pay $1300 out of my own pocket because my engine started overheating because it has a problem that kia could not find but is showing signs of the recall that was on this year make and model , VIN and everything the car currently will jerk whenever I’m going let’s say this speed limit 60 it will downshift all the way to 30 now this can cause a horrible, horrible accident

    I was driving down the highway going 75 mph and all of a sudden my car tells me pull over safely do not drive and it shut down while I'm driving. It never turned back on. It started smoking and you could see orange light coming through the vents. I was stuck on a [XXX] bridge for 4 hours and I missed court that day. I called Kia and they came to pick up my car. They said it was free because my car has been recalled but ever since they've had it, they stop answering my phone calls and emails and now they are trying to charge me 5000 to get my car back and fixed. Before any of this happened, I noticed an oil leak at the gas station but was unsure whether it came from my car or not.

    After careful inspection by certified auto mechanics at the service shop, "American Muscle" it has been determined that my Kia Optima 2012 2.0L Turbo has metal shavings in it from prematurely-worn bearings. While driving, my car suddenly went into limp mode from a knock sensor alarm while on the freeway. I took it to a professional repair shop, and they looked in the oil pan and found metal shavings from the bearings, both gold in color and silver in color. There was no engine light on prior to this event. It happened suddenly under normal, safe operation. It seems very similar to engine recalls of the same year and model due to metal shavings that resulted from engine manufacturing process causing premature wear of bearings. I have photos and video of the vehicle, the engine and oil pan with metal shavings present. The vehicle shows 100,667 miles at the time of the vehicle inspection.
