    I bought a used Kia sorento from a Kia Dealership. This engine makes oil evaporate completely. This engine must be a bad engine. I heard there was some recalls on Kia engines not sure if this one fits it. The dealership did a five hundred dollar job on it and it did not fix. I put oil in this car every month. No way to upgrade because of these issues.

    I had an engine failure in my Kia. On [XXX], I was driving on [XXX] in Maine, and the "malfunction" light lit up, and I lost power in the vehicle. I was able to make it to the side of the highway and call a tow truck. Losing power on a busy interstate put myself and my partner at risk, as well as having to wait on the side of the interstate for a tow truck. I had the vehicle towed to a mechanic who said the engine needed to be replaced because a cylinder lost compression. Kia had me tow it to a Kia dealership, and they verified that the engine needed to be replaced. The matter is still open. My case with Kia is [XXX]. Kia has been completely unresponsive in the matter. They have told me repeatedly that the matter is being looked into by their tech team, but they have never reached out to the Kia dealership they told me to send it to. It could be related to a rod bearing issue, but they are not willing to follow up enough to even determine whether or not that is the issue. Prior to the engine failure, I had issues with oil loss. I replaced the PCV valve, but that did not turn out to be the problem. I had it inspected a few weeks before the engine failure, and they noted that the oil levels were low. I was not seeing warning lights for low oil, but I was maintaining oil levels while I waited for an appointment to look into that issue. I believe Kia knows this is an ongoing issue with their vehicles, and they are actively obstructing any inquiries as to why this engine problem persists.

    I am experiencing a serious issue with my 2018 Kia Sorento AWD related to the AWD coupling. During normal driving, the vehicle does not perform as expected, and the AWD system feels compromised, making the car unsafe and unreliable. While the vehicle doesn’t stall, it struggles to function properly, which is a major concern. I took the vehicle to the dealership, where they diagnosed the problem as a malfunctioning AWD coupling. However, they informed me that this issue is not covered under warranty or any recall program. This response is both frustrating and concerning, especially since AWD functionality is a critical part of the Sorento’s design and intended use. After researching, I found that many Kia Sorento owners have reported similar problems with the AWD coupling, indicating that this may be a widespread issue across multiple model years. If this is a known defect, it is troubling that Kia has not offered a recall or extended warranty to address the problem. Customers should not be left to bear the financial burden of repairing what seems to be a common and significant defect. I am requesting further clarification and assistance. I need to understand why this issue is not covered, particularly if it affects other Sorento vehicles as well. If this is a systemic problem, Kia should take responsibility to resolve it fairly and promptly. The AWD system is essential for safe driving, and as a loyal customer, I expect Kia to stand behind its product and ensure my safety and satisfaction.

    Around 90,000 miles, the engine started leaking oil regularly, took it in for warranty. After repairs for gasket, then started burning oil and running of oil every week or two weeks, and I have to constantly refill oil. Took it again and Dealer told me I am out of warranty, then I called KIA USA and reported problems. They told me that they will get back to me and I am still waiting.

    While driving on the highway, the engine suddenly stopped working without warning. I was unable to accelerate using the gas pedal. Fortunately, the highway was empty at the time, and I managed to safely pull over to the right side of the road. After waiting for approximately 30 minutes for the engine to cool down, I attempted to drive again. However, the car began shaking severely whenever I pressed the gas pedal or attempted to increase the speed beyond 2 RPM. The vehicle was subsequently inspected by a certified Kia service center, where the issue was diagnosed as a failure of the piston ring and cylinder 1, resulting in insufficient compression. The service center confirmed that the vehicle was well-maintained, with no external damage or user-related issues contributing to the failure. No warning lamps, messages, or other symptoms appeared prior to the failure. The engine issue was sudden and unexpected, posing a significant safety risk, especially as it occurred while driving at highway speeds. The vehicle is available for inspection upon request.

    I have a pearl white 2018 Kia Sorento, and the paint is peeling off the hood. This is a factory defect, and I need to get it fixed before the rest of the paint comes off the car.

    Previous Complaint# 11618337. Additional Information: Engine is full of oil yet Oil Light comes on due excessive crankshaft & connecting rod bearing wear and knocking loud. Yet the recalibrated knock sensor will not pick up the issue and put the vehicle into derate with a code P1326 as it did before the Kia Dealership performed this recalibration. This is consumer fraud by purposely hiding a known defect and preventing the warranty from replacing the engine with a redesigned new engine that corrects the issue with larger oil ports. It is also a safety issue!! Now that the oil light is coming on and the engine has a bad knock, it can fail at anytime while driving causing lose of power steering, brakes and the ability to safely pull the car over to a safe location. The original P1326 code automatically determined the engine developed wear from lack of oil volume based on the known defect of too small oil ports. This recalibration doesn't address the wear the engine already has and based on what the dealer stated, they will not replace the engine until that code comes back. Which now can't happen due to this parameter change and elimination of the knock sensors ability to perform it's job correctly. Please investigate and resolve, Thank you!!

    My kia Sorento is involved in an engine recall. When driving on the highway three times now my engine has stalled and car has gone from 65 to 30 mph, almost causing multiple accidents while driving with my [XXX] and [XXX] . The Kia customer service agency said this must occur three times before they will replace my engine. They are not replacing the engine. I fear for my life, my husband life and my children’s lives . I also fear for fellow drivers on the road . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
