Dear National Highway Transportation Safety Administration, I am writing to bring to your attention a grave safety concern regarding my 2019 Kia Optima SX. Despite diligent maintenance and care, my vehicle has experienced persistent alignment issues, particularly on the right side. Additionally, I have encountered premature axle shaft and axle boot failures, all of which have occurred well before reaching 60,000 miles. These issues have not only posed a significant financial burden but have also jeopardized the safety of myself and other road users. The repeated alignment problems have resulted in the rapid deterioration of tires, leading to baldness within a month of replacement, creating a hazardous driving condition and increasing the risk of accidents. The premature failure of axle shafts and boots is unacceptable for a vehicle of this age and mileage. Such failures not only compromise the vehicle-??s performance but also raise serious concerns about the overall quality and safety standards of the Kia Optima SX. I urge the National Highway Transportation Safety Administration to conduct a thorough investigation into these recurring issues affecting the 2019 Kia Optima SX model. Immediate action is necessary to ensure the safety of consumers and to hold Kia accountable for any design or manufacturing defects contributing to these alarming problems. Your swift attention to this matter is crucial in preventing potential accidents and ensuring the well-being of motorists nationwide.

Two thefts of my 2019 Kia Optima in less than one year; 9/12/2021 and 7/30/2022 due to Kia's negligence in fixing a very obvious security flaw and lack of engine immobilizer. I have spent approximately $2,500 of my own money between insurance deductibles and replacing items that were stolen from my vehicle in addition to the actual vehicle theft. The thefts caused over $13,000 of damage between the two claims, and surely have depreciated the value of my car significantly. Thousands of Kia customers are negatively affected by this negligence, and we are being punished and violated for owning compromised vehicles. I feel incredibly unsafe driving my vehicle anywhere knowing full well it could be stolen at any moment.

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.

Parked. Started car & all dash lights lit up. Tried restarting no change. When backing up there was no power steering. Turned off ignition, pumped gas pedal 3 times, restarted & it seemed to fix problem. Took car in for electrical recall 1 week later & was told this might fix the problem. 2 weeks later it occurred again. Same solution used with success.
