    While driving doesn't matter the speed, my car doesn't accelerate and jerks, it had does these many times and I take it into the shop, at least 3 times now, and they can't find anything. Since it doesn't do it when they test drive it, they don't know what is wrong. But it is very annoying, since there are times I have been on a highway and my car doesn't speed up.

    I got my engine replaced, after using 100 miles on the car I checked my oil there was no oil in the car, every time I try to go over 45 miles the car hesitates to speed up. I am constantly checking the oil weekly, the engine still makes the knocking noise, never again will I buy a KIA vehicle again

    3 months prior to my car going into limp mode I had an incident where I was on the highway and had to come to a stop of major traffic and suddenly my car cut off out of nowhere. I got it to crank after putting it in park, but it was very scary being on the highway thank God it was traffic to where cars wasn't going so fast. Fast-forward to my recent incident to now my car's now in limp mode (MIL) same situation different times was getting on the highway and started to pick up speed to accelerate to 60mph my engine light started to blink Non-Stop and here I am again in a terrifying situation to where I have to get back off of the freeway and I also was on my way to work now having to call in and praying and hoping nothing happens to me while trying to get my car home now I've called I'm certain dealerships decided to go with a dealership to get my recalls done and the dealer basically told me he told his mechanics to hurry up and do my recalls that he could do and get my car out of their shop and also told me to get rid of my car basically refusing to do what he's supposed to do regardless but I truly believe I need a new engine and that's why the dealer rushed me out I just want to know how can I get my vehicle fixed with no problems and also without dealerships denying me. I would love to hear back from you all to know my next step in getting my vehicle recall done please and thank you

    Engine failure I am writing to express my serious concern regarding the defective and unsafe vehicle that I purchased from Kia Motors. It has come to my attention that Kia Motors is selling vehicles with known defects that can potentially cause harm or even death to its customers. I demand immediate action to rectify this situation and ensure the safety of all Kia vehicle owners. On [XXX], I visited a Kia Motors dealership to address a recall for the ksds engine on my vehicle. I was told the service was complete and I retrieved my vehicle. However, in December 2023, my vehicle suddenly stopped working in a busy intersection without any warning. I had my vehicle towed to a Kia Motors service center, where I was informed that the engine had failed and needed to be replaced. A month later, I discovered that the ksds recall repair had never been performed on my vehicle. I ask so what happened with the recall they said at the time they didn’t have an engine available they were on back order .but the failed to inform me of this and I was driving around in a safety hazard. They messed up and want me to be responsible for there mistakes. An apology is not enough Kia Motors is still selling vehicles with this dangerous defect and denying customers replacements. I demand that Kia Motors fixes the engine of my vehicle at no cost to me. Failure to do so will result in legal action. I implore Kia Motors to prioritize customer safety by taking immediate action. It is crucial that Kia Motors either fix my vehicle I expect a prompt response outlining the steps Kia Motors will take to rectify this situation and ensure customer safety. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    Only 77k miles, all recalls addressed. Engine stopped going about 45 mph, was able to coast into a gas station luckily. Towed to a Kia dealer where it's been for 3 months waiting to be diagnosed. Kia won't reimburse towing or rental until it's diagnosed. I paid $350 to get it diagnosed. They are saying it'll be another couple weeks before that even happens. I can't afford constant rental car. This has been a nightmare.

    I have experienced several issues with my Kia. I have replaced catalytic converter (direct fit), and the valve covering gasket. However, the engine reports issues every other month. The dealership dismissed everything stating that the engine is fine. But wherever I take the car to get an oil change, they say I need to contact the dealership. I have been consistently managing my car maintenance but it does not help.
