2019 Kia Optima: hesitation when accelerating

Filed Jun 3, 2024 · Engine, Fuel system · MD

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 federal safety agency 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 purchased on my 2019 kia optima on 6/19. And since then off and on the car has experience intermittent starting issues. Now I have taken the car to two different dealers and neither one can find the problem. When pressing the stop/start button the car would hesitate to start no lights or codes are stored in the computer. I have contacted kia about the issue all I was ever told was take it to the dealer and let them inspect it. The dealer would reset and update firmware. That would last for a minute but eventually the car would go back into the same thing of hesitating. The car has been into the dealership multiple times for the same issue kia has opened case after case but no solution. The car is considered a lemon by state statues. Not one time has kia offered to take the vehicle the only thing I'm told that if it happens again bring it back. I would spend more and miles taking the car to the dealership. There is also an issue with the wheel alignment the left rear wheel always need to be aligned I'm not sure why but when I take the car for an alignment that wheel is always out of specs.

I bought my 2019 optima brand new back in november. It is now june and I have had it back to the dealership 3 times for randomly not starting on me. I get the same answer every time. They don't know what it is, nothing comes up on the computer when they plug it in. They say, "if it happens again, call us and well take it in". Buying this car brand new and my payments being that of a range rover, I am extremely upset. To top it off, the back windshield is slipping down. I am over this car and I will never buy another kia again. But, my fight is not over, something will have to be done. It also hesitates at times, feels as though it is struggling to go. Also, two times while I was driving the car, the dash lit up with almost everything like, I was in a crash, the exclamation point, etc.
