KIA Complaints

My car started shutting down while driving. After the engine started seizing the key wouldn't turn in my ignition. Took car to dealership immediately on 10, 2026. Took again in 2024 for recall and other repairs. Found out after requesting previous service incidents they failed to do recall repairs and never notified me of it, or to come back. I've requested current diagnostic report several times in writing and verbally with codes for this current service, with non compliance. My car is still at the dealership needing work and I need current diagnostic report before I pay for repairs. I am attaching a dealership diagnostic e-Report for my 2013 Kia Optima from 2024. While the report lists “No Current DTC” for several systems, it also documents multiple “Communication Fail” errors across critical modules, including Smart Key, Head Lamp, Air Conditioner, Brake, and other systems. These communication failures indicate a broader electrical or network issue within the vehicle, not simply a failed battery. The report also shows that certain diagnostic scans were not properly performed. Additionally, there are historical fault codes related to TPMS and weight classification systems, further supporting that the vehicle has experienced ongoing electrical issues. Despite these findings, the dealership attributed the vehicle failure solely to a bad battery and did not provide a current battery diagnostic test. They also failed to address an open recall related to electrical/fuse issues prior to this failure. Based on this past diagnostic report, I believe the root cause of my vehicle’s failure is an unresolved electrical defect, potentially related to the outstanding recall, rather than normal battery wear. This has resulted in my vehicle becoming inoperable and poses a serious safety concern.

Referencing report [XXX] We are having issues getting the fuel filling door to open. We have unlocked the car, several times, but it will not open. We had to pry it open so we could fill the tank and have left it open since as to not have the issue again. Part number in question - 81560R5000 There are other recalls on the car that we need to get taken care of. Is this another one in addition?

Vehicle: 2015 Kia Cadenza Issue: Open HECU Safety Recall — Fire Risk I am the owner of a 2015 Kia Cadenza with an open HECU recall related to a known fire risk. I have been experiencing a burning smell inside the cabin of the vehicle, consistent with the recall defect. Upon contacting Kia Consumer Assistance, I was advised not to drive the vehicle due to the fire risk and to have it towed to a dealer. However, after calling multiple Kia dealers in the Pittsburgh, PA area, the earliest available appointment is over one week away. Kia Consumer Assistance called dealers on my behalf and was unable to secure an earlier appointment. They said they could "Look into a potential reimbursement of $55/day for a rental vehicle." but could not confirm a loaner. I am concerned that Kia is not treating this recall with the urgency a fire risk warrants. I WAS NOT PROACTIVELY CONTACTED ABOUT THIS RECALL DESPITE MY VIN BEING AFFECTED. I am now without transportation, my vehicle cannot be safely driven or stored in an enclosed space, and I am waiting over a week for a repair on a vehicle that could combust. I am requesting NHTSA review whether Kia is adequately addressing this recall with appropriate urgency and dealer capacity.

The mechanic informed the contact that the failure was related to an unknown engine recall, and the contact was referred to the NHTSA Hotline for assistance. The manufacturer was not yet contacted. The failure mileage was approximately 91,000.

On 3-21-26 I noticed the smell of gasoline after driving the vehicle. Upon inspection a noticeable fuel leak from the top of the fuel tank was evident from underneath the vehicle. Further inspection found fuel leakage at the fuel pump outlet line. After online research it was found that other vehicles of this type have hairline cracks on the fuel pump outlet causing fuel to spray out under pressure. Fuel pump assembly replacement has repaired the problem. No indication other than the smell of gasoline was noted at any time. This is a safety hazard that should be addressed ASAP. Part removed has only been inspected by me. Part is available. If I had not been diligent in addressing this problem the consequences could have been catastrophic. The fuel outlet on a high pressure pump should have never been allowed to be made of plastic. People's lives are at risk!
