My vehicle came up with a check engine light blinking. I took it to a Kia dealership where they put the ksds update in. A week after driving it, I started experiencing loss of power and the check engine light came back on. But this time not blinking. My car accelerates slowly, it is a struggle to get to 30 mph. My engine is making loud noises as if I am flooring the gas pedal when going 10 mph. Hills are impossible and dangerous to drive up. I took it in where the man told me my oil was empty, when just the day before it was full. I ran the code reader which came up p0010 for a camshaft. Now I'm being told it's the entire top motor needing replacement due to "no oil". I saw online recalls for this exact issue on the engine. It states of a lifetime engine warranty for this qualifying engine problem. …

While driving my 2017 Kia Optima (Theta II engine) at approximately 115,900 miles, I suddenly experienced engine failure. The vehicle began to stall and produced a burning smell shortly before the engine seized completely. I had the car towed to a Kia dealership, which confirmed an internal engine failure and noted that there were no signs of external oil leaks or neglect. The failure occurred only 4,500 miles after my last oil change, which was documented and professionally completed. The Kia technician mentioned verbally that this was due to excessive oil consumption and burning - an issue I later found to be widely reported in other Kia vehicles using this engine type. The estimated repair cost is over $14,000, which is more than the value of the vehicle. Despite my warranty being expired, this type of failure appears consistent with known manufacturing defects. …

i had engine light a code P200a on my 2017 kia optima ex 17,000 miles i have like a hesitation when accelerating, sometimes just sitting idling or sitting at a light feels like going to stall. i had some one check it they told me to bring it to the dealer because they looked it up and said it is like a recall on 2016 kia optimas there is a Technical Service Bulletin on the same condition that i have i went to the dealer and they said thats what it was the (VCMA)variable charge motion actuator on the intake manifold..i dont drive to much with the car i looked on line and a bunch of people say they had the same problem with my year and older models.thank you.ihad it fixed at the dealer on 8-30-23 case #15777155

I own a 2017 Kia Optima with a major internal engine defect. Starting shortly after purchase, the car lost power and consumed fuel unusually quickly. Over time, the engine began burning excessive oil and now produces a loud knocking sound (bearing knock), indicating internal bearing failure. These symptoms are consistent with known Kia engine defects (bearing wear / piston ring failure). The defect is a serious safety concern: because of weak bearings and high oil consumption, the engine could stall, seize, or catch fire. The dealership has refused to repair or replace the engine. I am reporting this as a safety defect and request NHTSA investigation.

The KSDS in my engine is causing engine failure due to the dealership failing to fix the problem when I first experienced stalling, lagging and misfiring of my vehicle, which would often make it shake and I would have to turn the car off and reignite it, sometimes more than once. My safety is at risk when driving, because the vehicle will lag while trying to accelerate in traffic. My mechanic researched the issue and found the recall and Kia said they fixed it when it was issued and they didn't. My CHECK ENGINE light is flashing now and it continues to lose power. I have contacted Kia about the issue and I'm waiting on a response.

My car is consuming major oil. I am having to put at minimum 3 to 4 quarts of oil every 3 days. I am having major loss of power. My car has oil fouled far too many spark plugs. In the last 3 months, I have had to replace the spark plugs three separate times. Within the last 3 weeks I have replaced the following: 1. Ignition Coils 2. Valve Cover Gasket 3. PCV Valve 4. 2 separate sets of spark plugs and 1 singular spark plug for Cylinder #4. My car is having a major oil consumption problem and the performance has been severely affected.

The vehicle will shake during acceleration. It comes without warning and will cause the check engine light to flash and stay on for about a minute. It goes away on its own. However, there do not seem to be any stored codes, according to my personal OBDII scanner. The dealer refuses to take it in because there is no check engine light. However, this has happened in several occasions and could lead to an accident. The dealer appears to be waiting for the warranty period to run out.
