Owner report 11691853 · 2025-10-07 (October 7, 2025)
For starters, my lights go out every six months on queue. Cannot find a reason why. My car sputters or shutters when accelerating. I heard other Kia models have recalls due to the same thing. I have had my car in the shop multiple times and no one can figure out why it is doing it. It feels like the belts are slipping or the transmission is slipping or something, but no one can find a legit reason as to why. This has been happening since I bought the car and it has never stopped with anything I have tried to do or I’ve had inspected.
