2020 Kia Optima

While driving, the vehicle experienced a sudden loss of engine power and entered limp mode. The check engine light began flashing and the vehicle had very limited acceleration, creating a safety concern when driving in traffic. The vehicle was towed to a Kia dealership for diagnosis. The dealer retrieved diagnostic trouble code P1326 (Knock Sensor Detection System – range/performance). During inspection, the dealer found metal contamination in the engine oil and oil control valves and advised that the engine has internal damage and requires replacement.

Took to Kia for engine burning excessive oil. They determined the cylinder wall was scorched due to piston ring. The warranty people say it’s normal wear and tear and won’t honor the warranty. It’s still sitting in their engine bay because they want me to pay for the diagnostic which I don’t have. $4000 roughly for that but it needs a new engine. The warranty should be covering this! NEVER PAY FOR AN EXTENDED WARRANTY!!! They will not help you

I got the car was running good week or 2 later I see the oil light flash after my oil change I go back top it off repeat the cycle almost weekly burning losts of oil then I get a code p1326 for a knock sensor same day car go into limp mode no power rpm won’t go over 2 car won’t go over 60-65 I park it go outside to take it to the dealership next day it ain’t start I haven’t had the car 4 months only have 138,000 miles

Out of the blue I get a code for a misfire on cylinder one. Got in to head to work as normal and it was stalling and shaking so bad that I am scared to drive it. The next day the check engine light was on when I started it to seek out the issue. Car was manufactured in September 2019 but is the 2020 model year. I was told by a license mechanic this is related to an internal Kia engine issue. I contacted 800 333 4KIA to see if this was a known issue that they had a solution to. Of course I was told to self repair that my VIN is not covered under the recall. Can you tell me how Kia assumes that engine issues with the 2019s model year would have been fixed before the 2020 models were assembled? Sounds like my dream car is now my nightmare. 3rd White Kia Optima but I am likely leaving the Kia family if this requires a new engine.

I have kept up on regular oil changes and maintenance on my Kia which I bought new 5 years ago. My issues started when my car's orange check engine light came on, I experienced loss of power such as difficulty accelerating even at low speeds, especially up hill. As soon as I was able I checked my oil which and there was nothing on the dipstick. I put in 3 quarts of oil. I brought it into my usual dealership for service and let them know about the oil issue and issues with power when driving. They failed to address the root cause of the issue, they performed an oil change, engine light turned off, and they started an oil consumption test. But when I drove off the lot the issue with the power continued, and the check engine light came on again. I took my Kia to another dealership to address the car's power issue and the first oil consumption test was not completed because it was unsafe to drive. When I brought my car in, the check engine light was not on, even though there were significant power issues. The dealership was able to confirm my concern, including loss of power and evidence of oil overconsumption. They replaced my turbocharger under warranty. I then underwent a 2nd oil consumption test that indicated overconsumption at a level of 1.5 quarts per 1000 miles. Then they performed a combustion chamber cleaning per Kia guidelines and a 3rd oil consumption test. They 3rd oil consumption results indicated overconsumption at a level of 0.75 quarts per 1000 miles. Although the dealership acknowledged this is still overconsumption, it was not to a level that required Kia to replace my motor. Meanwhile, after all these tests my car is close to out of warranty, at 98.6k miles. I called Kia customer care and their "resolution" to my case was the deny me a new engine and they would not provide me anything in writing. My car's overconsumption of oil and other signs of engine failure match the complaints found in class action settlements related to other Kia models.

My car has been burning oil rapidly. I’ve contacted kia over this issue and I have had several times where I have had to continually add oil. There is no leak. This is a known issue with kia motors across mechanics nationwide and there should be a recall issued. This has been at several shops and over the last few years. This motor should NOT be consuming 4 quarts of oil within 1000 miles after an oil change.
