Engine failure at 15 months old and 42,000 miles. Kia denied warranty coverage because I could not prove oil changes. Same complaint as thousands of other Kia vehicles, happened abruptly, car starting making loud rattling noise on acceleration while driving, no warning, sludge in engine. I had to pay out of pocket for a new engine to be installed with no assistance from Kia or my local dealership.
My 2015 Kia Optima has 23000 miles.. I couldn't remember when I had the oil changed, but I was driving on 75 coming from fla. The ac stop working and then shortly after that the car started to slow down. It finally came to a complete stop, when I got it to the Kia dealership they informed me that the engine had seized.because the said I could not prove that the oil had been changed, the warranty would not cover it. I bought the car brand new. Only had it 15 months. There was no warning lights or any signs of trouble.Kia will not fix it, they want almost 8.000 to put in a new engine.
As I was driving my 2015 Optima to the store my check engine light came on. The next day I started my car and heard a rattling or ticking sound, this was on labor day, so I turned my car off and called the dealership. Due to holiday the service dept was not open. I called them again on Tuesday Sept 6th and was advised they would have it towed. I received a phone call on Tuesday evening stating my motor has sludge and needs to be replaced.
2015 Kia Optima, only 47K miles....engine failure...the dealership says its sludge... and I have to provide all my maintenance records. It started with white smoke coming out of the tailpipe and loud rattling noise when I accelerated, then this past Saturday, it started to shake violently and the check engine light went on. I had to get it towed. This is Kia's fault!!! not mine. I've done the same routine maintenance on my Toyota and Honda which had over 100K miles with no problems! I am being told by Kia that it won't be covered under the warranty.
My 2015 Kia Optima has 26,456 miles. The last oil change was performed at 26,064 miles. On 6/4/16 while driving approx. 50mph in 3 lane traffic the engine seized up, car shut down and interior filled with smoke. Had vehicle towed to Kia. Was told it needs a new engine due to sludge in the oil. Kia is refusing to honor the warranty because I cannot produce receipts for previous oil changes. I have researched and many other Kia vehicles are having very similar problems with low miles! there has to be something wrong that Kia is not aware of or is just not willing to admit. Not only will they not fix my vehicle but I fear someone is going to get hurt or even killed. I informed Kia of my concern but they did not seem to care.
