I am filing this complaint due to severe and ongoing safety defects in my 2020 Kia Optima EX, which has repeatedly stalled while driving, creating a life-threatening road hazard. Since September 2024, my vehicle has suffered from major failures, including a complete transmission replacement, multiple high-pressure fuel pump replacements, multiple oil flushes due to fuel contamination, and all fuel injectors replaced. Despite all of these -??repairs-?? performed by a Kia-authorized dealership, the check engine light continues to return, and the vehicle still stalls unexpectedly, making it dangerous to drive. On March 10, 2025, after Kia claimed to have tested the vehicle for 200 miles, I picked up the car from the dealership, only for it to stall and trigger the check engine light within hours before I even reached my destination. This vehicle has been returned to me multiple times in an unsafe condition. Additionally, an independent mechanic discovered an engine oil leak and a torn axle that Kia-??s dealership never disclosed. This raises major concerns about their lack of proper inspection and repair procedures. This is a serious safety issue that Kia refuses to take accountability for. I request an immediate investigation into this matter before this defect leads to an accident.

I was stopped at a red light and the car stayed on but just stopped working. I had to wait for it to reset itself, or at least that was what it felt like it was doing. I got the oil changed in it the next day and about three weeks later the low oil light has come back on.
