KIA Complaints

premature wear of the motor-driven power steering (MDPS) flexible coupling. This wear causes a "knock" or "clunk" noise when turning the steering wheel, especially at a stop, and may be accompanied by a tight or loose steering feel.

On [XXX], while driving my 2017 Kia Sedona on a road trip through Killeen, Texas, the engine suddenly began making a loud knocking noise without any prior warning, leading to catastrophic engine failure and complete loss of motive power. The vehicle became inoperable and was towed to University Kia in Waco, Texas. The day prior, on [XXX], the vehicle underwent a thorough pre-trip inspection and full synthetic oil change at Sun Auto Tire & Service (5117 Golden Triangle Blvd., Keller, TX 76244), confirming it was roadworthy with no issues detected initially, though oil was found leaking afterward (maintenance records attached). University Kia confirmed the catastrophic engine failure, likely related to the 3.3L Lambda engine's known oil pressure switch (OPS) defects, as the OPS had been previously replaced under warranty. Kia Motors America (Case [XXX]) denied liability unless I pay $3,000 for a teardown inspection to prove the failure was due to the OPS, despite the vehicle's eligibility under the WTY026 extended warranty (15 years/150,000 miles). This failure aligns with similar complaints and NHTSA investigations into 3.3L Lambda engine issues, such as oil starvation and sudden seizures. Due to the failure, we missed a prepaid hotel stay in San Antonio, incurred additional hotel stay charges as our trip had to be extended, and incurred costs for a rental vehicle to complete the trip.

Over the past couple years, the check engine light has came on and I immediately had a mechanic look at it. The first time they said it was my spark plugs and changed them. Then this year, a year later, the check engine light came on and it became hard to accelerate on my way to a mechanic. Once again, they said spark plugs, so they changed them and claimed that they didn't look to had been changed before. Now here I am a couple of months after that, my check engine light came back on and my car started making a funny noise on my way to work. I turned back around and went home since I was closer to home than work. It sounds like rocks popping when you start it or hit the gas. I had someone check the codes and it said engine 1 and 4 coils. All 4 coils and spark plugs were changed again. That did not fix it. The sound is still there and the engine light is now blinking. I have kept up with the oil changes and everything. There is no recall. I still owe on the car and it is not able to be driven.

My car is consuming oil. I was two and a half quarts down when I checked it and the oil light never came on! I'm glad I checked it when I did! The car is consuming oil and has to be checked every day to every other day. I called the local KIA dealership and of course, NO RECALLS. What do I do now?

After picking up my 2013 Kia Optima from a Kia dealership for an engine recall repair, I was told that no issues were found with the vehicle. The following morning, while driving on the freeway, the vehicle suddenly stalled without warning and lost power in the middle of traffic. This created a dangerous situation, as the driver was left stranded in an active lane with vehicles traveling at high speeds. Prior to dropping off the car, multiple independent mechanics and a body shop had advised that the vehicle was unsafe to drive due to engine concerns. The dealer stated they could not reproduce the issue and cleared the car for use. However, within hours of getting the car back, the stall occurred. The vehicle is currently available for inspection. The problem has not yet been confirmed by the dealer, but the symptoms are consistent with known Kia engine failures related to connecting-rod bearing wear. Before the stall, the check engine light had intermittently illuminated, but the dealer reported “no issues found.” This failure put the driver and surrounding motorists at serious risk of a collision and highlights that the recall remedy may not have addressed the underlying safety defect.

The fuel input is not working properly. Will not allow fuel to go into fuel tank. Risk of fuel spilling and fire hazard.

The 2025 Kia Carnivals have a safety systems that prompts the driver to, "Take and coffee break". The system cannot be turned off and is extremely distracting. The system prompts the driver even if the adaptive cruise control is turned off. I called Kia and they told me to take the vehicle to the dealer. The dealer was not able to turn the computer nag off either. The car makes a noise and the prompt flashes at the driver every few miles. This happens when traveling at highway speeds and in traffic. The driver has to look down from the road to see what the noise is and is greeted with the infuriating "Take a coffee break" message. It is extremely distracting and annoying to the point it induces road rage. The NTSB needs to investigate this system and require manufacturers to either allow owners to turn it off or do not include this feature in their vehicles. The next question is irrelevant because this happens on almost every highway drive. It is not a one time occurrence.

Unknown. Fire was located under in the engine compartment area and fire was visible from below the engine under the car. When it happened I was driving on the freeway when noticed my car seemed to be struggling stay at the current speend and to loose speed then a it suddenly l no longer would accerlatoed so I pulled over to call 911 a passing vehicle stopped and informed me there was flames under my car. I safetly exited and called for emergency services. The Safety risk of major bodily harm by fire to myself or risk of harm to the environment around me a risk. The check engine light had come on before the fire. Reached out to manufacturer for a fire investigation and was instructed to take car to dealership to for service department to inspect. Was told a ETA of 2 weeks before they will check out my car.

Out of no where my engine just started knocking. No engine light came on, no oil light came on, no warnings at all. I just got an oil change 12/18/2024, with 2 top offs 04/23/25 and 07/23/25. And August 24 th my engine started knocking. I took it to Midtown kia on 08/25/25 and they told me Kia customer care won't cover the engine recall.

I started my car and it started shaking violently, and would jolt back and forth, I would be on the highway and the speed would decrease rapidly and overheat slightly to pick up speed
