Subject: Complaint Regarding Excessive Oil Consumption and Engine Hesitation in 2019 Kia Optima SX To Whom It May Concern, I am writing to formally lodge a complaint regarding my 2019 Kia Optima SX. Despite meticulous maintenance and care, I have been experiencing significant issues with the vehicle that are concerning, especially considering its relatively low mileage of only 107,000 miles. The primary issues are as follows: 1.Excessive Oil Consumption: My Kia Optima SX has been burning an excessive amount of oil, necessitating frequent top-offs well before the recommended oil change intervals. This is not only inconvenient but also raises serious concerns about the long-term health and reliability of the engine. 2.Engine Hesitation: The vehicle exhibits extreme hesitation during acceleration. This hesitation occurs sporadically, making it difficult to anticipate and presenting a potential safety hazard, especially when merging onto highways or attempting to overtake other vehicles. These issues are unacceptable for a vehicle with such low mileage and are not in line with the quality and reliability I expected when purchasing a Kia. Given the prevalence of similar complaints from other owners of the same model, it is evident that these are not isolated incidents but potentially indicative of broader manufacturing or design flaws. I urge the National Highway Traffic Safety Administration (NHTSA) to investigate these issues thoroughly. Owners of the 2019 Kia Optima SX should not have to endure such significant and potentially dangerous problems with their vehicles. Thank you for your attention to this matter. I look forward to your prompt action and response.

I currently have 119500 miles on my 2019 Kia Optima. I am losing oil somewhere between oil changes, and the car is beginning to hesitate while driving. I don't see oil on the ground but I have had to put in 2-3 1/2 quarts of oil way too often. For this to happen on some many vehicles, it must be a manufacturer defect. The hesitation just started and I'm taking it do get a diagnostic test. 11

I am writing to bring to your attention a critical safety issue with my 2019 Kia Optima SX 2.0 GDI Turbo, which has accumulated approximately 103,000 miles. This vehicle has recently developed several serious problems that I believe pose significant risks to both my safety and the safety of other road users. Firstly, my Kia Optima has been burning an excessive amount of oil. Specifically, it consumes over 5 quarts of oil within just 2,000 miles of driving. Despite thorough inspections, even from Kia Dealers there are no visible oil leaks, making this issue even more perplexing and concerning. Moreover, the vehicle has begun to shake violently while driving on the highway, which has led to a substantial loss of power in the middle of traffic. This unpredictable loss of power is extremely dangerous, especially at high speeds, as it compromises my ability to maintain control of the vehicle and poses a significant hazard to other motorists. Additionally, the car now emits a loud knocking noise, which appears to be related to the engine's internal components. This issue further exacerbates the vehicle's performance problems and raises serious questions about its reliability and safety. I urge the NHTSA to investigate these issues promptly. The problems I am experiencing are not isolated and may affect other Kia Optima owners, potentially leading to widespread safety risks. I believe it is crucial to determine if there is a manufacturing defect or other underlying cause that needs to be addressed to prevent accidents and ensure the safety of all Kia Optima drivers. Thank you for your attention to this matter. I am hopeful that the NHTSA will take immediate action to investigate these serious safety concerns and provide a resolution to protect both myself and others.

The engine is consuming oil very fast and needing oil way before the next oil change. The oil consumption test Kia did stated that it was 2 quarts low after the first 1000 miles. Car does not have extended warranty but this a manufacturing defect. Suggestion was new motor. Also it's recall for the forward collision safety feature but my car vin is not included even though it goes off when nothing is in front of me. They want me to pay for these issues the motor cost the same as the payoff of car. This is ridiculous, I purchased Kia due to having a older model that almost got 300,000 miles on it before transmission died. I got a great payment and a newer car but didn't expect to have this motor issue or safety problem with no help from manufacturer. I'm stuck keeping oil in car so it's burn out & cutting safety feature off so it stops breaking when nothing is in front me. Both of these issues or manufacturing defects and should be fixed by KIA.

2019 Optima EX excessive oil consumption. Oil changed every 3000 miles, but is always empty within 1000miles. Car has 101,000 miles. Took to Kia dealership due to loss of power on acceleration and stalling and excessive oil consumption, they said I have multiple misfires on cylinder 1, excessive sludge buildup under cap and again no oil present. I was advised the engine needed replaced and that somehow this is a me problem and not a Kia problem. Spoke with Kia support and because it’s 1,000 miles over warranty they will not do anything even though they are aware of excessive oil consumption issue in these motors

I own a 2019 Kia Optima whose paint is peeling off rapidly. The paint began peeling in a tiny spot that I thought was a chip from a rock but has now grown to several spots peeling all over. I first noticed this in 2020 I visited my dealer on January 2024 to no avail. Not only was their technician rude, but he also said the paint was not covered under KIA’s bumper to bumper warranty. I have bought the extended bumper to bumper warranty at the dealer. I’ve owned several cars in my life and have never had this problem with any of them. I currently own a 2003 Toyota whose paint is in much better condition than my 2019 Kia. I believe this is a factory defect with this paint color and would like you to further investigate and help to restore my KIA so that the peeling stops. I’m attaching several photos for your review. The color is Snow White Pearl.

Engine is consuming extreme amounts of oil. I have never been late for an oil change, and often go before I’m even due. My car was stalling and the RPM was fluctuating. I had to pull over and turn the car off. I then noticed my oil light on for 2 seconds, then it turned off. I’m not due for an oil change for another 2,000 miles. I pulled in to a mechanic shop (thankfully I was right next door) and low and behold, hardly any oil in my car. Had maybe half a quart left. I should have been good for another 2,000 miles. This is not the first time this has happened either. I no longer feel comfortable driving myself or my kids in this vehicle. It has been nothing but constant worry about my engine dying, burning or stalling. This car only has 70,000 miles on it and only 4 1/2 years old!!!! This is the second incident of this car jerking and stalling on the highway. Thankfully I’ve been able to pull over to avoid being slammed. I had the oil topped off so the engine could function, but once again, I was not due for a change.

Mar 22, 2024Engine

Was driving my vehicle when it started shaking violently and the check engine light came on. Took it to my mechanic and then it was towed to the Kia dealership. Both say that cylinder 2 won’t hold compression due to leaking valves causing oil to flood the engine and the engine to not work properly. I was told I could drive it still but that the engine could seize at any time putting us at risk for an accident. Kia says this is not covered under the extended warranty, but I have had multiple mechanics say this is an issue with 2017 and newer Kia’s and Hyundai’s,

Our 2019 Kia Optima has now stalled twice at a stop light in the past year. When it happens, we're able to restart the engine. In addition to stalling, the car struggles to start on some days and runs lumpy (minor surges in power) on other days. The symptoms match a problem Kia is aware of and for which it has provided an extended warranty (15 years/150,000 miles). Below is the wording from the extended warranty letter (2016-2020 MY Kia Optima Vehicles Low-Pressure Fuel Pump New Vehicle Limited Warranty Extension dated Sept 9, 2022): "If, at any time within the extended warranty period, you experience intermittent reduction in engine power, stalling while at idle, and/or inability or difficulty starting your engine, your authorized Kia dealership will diagnose the cause at no cost to you." When I took the car in after both incidents, the Kia dealer is not able to replicate the issue because it's an intermittent issue. There is no fault code thrown by the vehicle computer. The dealer and I have separately called Kia to get authorization to replace the low-pressure fuel pump (the most likely culprit), but Kia has denied the request because the dealer isn't able to replicate the issue. This is non-sensical given the fact that Kia in its letter admits that this problem is intermittent. I'm afraid that the next time the low-pressure fuel pump fails, it will be in a far more dangerous situation (e.g. highway) than at a stop light. I believe Kia should replace the low-pressure fuel pump for those owners who report the symptoms of a failing low-pressure fuel pump even if the failure can't be replicated at the dealer. Kia is basically saying they're not going to replace the low-pressure fuel pump until it malfunctions and stays broken which could very likely leave us stranded somewhere or worse without engine power in the middle of driving.
