My starter would not turn over to start my car after driving it. When I got to my destination I couldn't restart the car and there was smoke coming from under the hood. I had 2 starters put in thinking that was the issue and after the 2nd starter was installed the car still had smoke. The electrical wires were burnt and burning and the car still will not start.

Theta II engine failure while driving at high speeds (50-65mph) the engine began to make a loud knocking sound. Soon after, the check engine light illuminated as well as the oil light. I did pull over and contact my local Kia dealer and was advised to drive the vehicle to the service department. Upon inspection I was advised the vehicle needing a new engine. It had bearing damage due to metal shavings... surprisingly 3 months ago the vehicle was previously inspected for metal debris / engine bearing failure and no issues were found by the same local Kia dealer.

I was driving the vehicle on the beltway 495 in Maryland and the vehicle came to a stop without any warning on the dash. I attempted to start the vehicle but it wouldn't start. I check the motor, checking the oil stick showing that the vehicle had no oil in it. I never received a warning light about low oil or anything was wrong. I had my cousin bring me some oil. I put four cans of oil in the vehicle and it still wouldn't start. I had to get the vehicle taken off the highway to my cousins house near by. I purchased a new battery thinking that was now the problem. The started to turn over but wouldn't start. The next day I connected a check engine machine to the car, a actron auto scanner #cp 9575but no codes appeared. A friend who in the past raced cars check the motor from the attempting to start and stated it was the bearing in the engine. It would start and again I had no warning lights about the oil or engine before the problem with the engine. I checked the computer an founded out that other Kia's had similar problems with the warning lights not coming on to let you know about the oil was low. Kia had a problem with other vehicles 2012-2017 not showing a warning light on the dash.

The contact owns a 2012 Kia Optima. The contact stated that the headlights failed to illuminate and there was extremely poor visibility. Also, the oil light randomly illuminated several times. The dealer (ossett Kia South, 2680 mt moriah rd, memphis, tn 38115, (901) 328-8173) was unable to determine the cause of the failures. The contact replaced the headlight assemblies more than five times, but the visibility was still poor. The contact also noticed an abnormal odor in the vehicle. The dealer indicated that without the check engine indicator illuminated, they would not replace the catalytic converter. The contact stated that the warranty expired without the part being replaced. The fan also failed to function, but the failure was not remedied. The dealer also performed a repair per an unknown recall regarding the steering; however, the remedy failed to provide a solution for the steering coupler and the steering wheel was no longer straight. Also, the sun roof and moon roof glass had a crack going down to the driver's side of the vehicle where it met the windshield. There was also an abnormal noise progressing due to the failures. The manufacturer and dealer were notified of the steering failure, headlight failure, and moisture in the rear camera. The failure mileage was not available.

On January 24, 2019, my car had to be towed to shakers Kia in watertown ct again. I had been in ct visiting family when I got stuck there due to car issues. I dropped my car off December 7, 2018 for an engine replacement due to a recall and I got it back December 31, 2018. I drove my car home to nc on January 4, 2019 and came back 2 weeks later for my son's surgery scheduled for January 23. On January 22, three weeks after I got my car back, my check engine light came on and my car went into limp mode while driving and had to be towed to shakers Kia. They texted me at 9:08am January 23 with a link to a video saying my car was ready. I picked it up around 5pm after my son's surgery. I didn't have the car 4 hours when it did the same thing again and had to be towed. Shakers told me that I was gonna be responsible for replacing my throttle body because I still have old components from my old engine and my throttle body was part of that. I didn't understand how I have old components if my engine was replaced, so I called Kia headquarters. Shakers replaced my throttle body, no cost to me. Well, when I picked my car up on January 30, I asked about the fuel leak recall and if my car was inspected as Kia told shakers to check mines even though my VIN number wasn't included because my car needed to be checked because my engine was replaced due to the recall. I was told by the technician hector that my car was fine and it didn't need to be inspected because he was very confident in his work. He stated that people were having engine fires because mechanics don't know what they're doing and are installing the engines wrong. My car doesn't run the same after having my engine replaced. It runs and idles rough. I put in numerous calls to Kia about issues with my car and I'm told over and over again that my case manager will call me but it's been weeks and she hasn't called yet.
