KIA Complaints

The contact owns a 2016 Kia Sorento. The contact stated that while his wife was driving, the battery, check engine, and oil warning lights were simultaneously illuminated. The driver reported hearing a low rattling sound and observed smoke coming from the engine compartment. The contact stated that the dealer declined to service the vehicle because the knock sensor was not installed by the previous owner. The vehicle was towed to a local dealer, where it was diagnosed with a connecting rod bearing failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 98,000.

-Car was leaking or burning coolant causing engine to overheat. -Car was diagnosed with: Exhaust heat exchanger is leaking coolant and needs to be replaced. After costly repair, car continued to leak coolant and overheated. -Car was taken back to the dealership and diagnosed with: Engine Assembly - Long Block - Replace | Engine long block needs replacement due to coolant in the oil. This was at a certified Kia Dealership. No insurance reps or police were involved. An engine light has come on a couple of times over the years that was interpreted to mean replacing the gas cap. After replacing the gas cap, the engine light didn't come back on. My safety was impacted as a person living in a cold, rural state to have a sudden mechanical failure where I couldn't run the heat and had to stop the car immediately.

Was driving vehicle and it began to run hot, check engine light came on then started to make a knocking sound when getting to 30-35 mph. Was inspected by a service center. There it was confirmed an issue with the motor/head gasket

The engine seems to be failing/affected. The vehicle is currently available for inspection at Huffines Kia in [XXX] where it has been since Saturday, March 14, 2026 and they have yet to perform the SC336 Safety Recall while trying to charge a diagnostic fee for a multipoint inspection that I did not ask for. The vehicle would not start which now I know is due to total oil consumption, which appears to be a precursor to the recall. Having a vehicle that can catastrophically fail or stall without warning due to defective piston rings creates extreme risk of a crash or fire while my family is inside. The service department at Huffines Kia Mckinney confirmed to Kia Corporate on Wednesday, March 18, 2026 that the vehicle was completely depleted of oil. However, they have not officially confirmed the recall failure because they have not done the recall test. They told corporate that they haven't done the recall because I did not have oil in my car. They have had my car since Saturday, but have not topped it off with oil since it has been there for several business days. I have also opened a formal case with Kia Corporate (Case #XXX) due to the dealer not providing the free safety remedy required by law. There was no oil pressure warning light prior to the failure, however, when trying to start my car and it wouldn't start, the oil and engine light came on. A tow truck came to tow to the dealer. The tow driver was able to start my car using a jumper box. The dealership says my car ran fine and no oil or engine light was on. However, if they ran my car knowing it was depleted of oil, they have potentially further damaged my engine.

On 7 March 2026 our Kia Sportage PHEV died its first time on the highway with less than 1000 miles on it. There were no warning lamps or messages before the issue happened. The car's acceleration pedal stopped working and it slammed us from 70mph to less than 20mph. It had a loud grinding noise and the check engine light came on. My family was almost hit by a semi truck because of this. The car was immediately taken to the Kia dealership we purchased it from. A few days later they told us it was the "high pressure fuel pump" that failed. I asked them to check the fuel system or the engine oil to see if there was any glitter, then, because the grinding noise we would have heard is metal on metal. And any small metal shavings in the wrong place would cause another catastrophic issue. I also asked them if they checked the cam lobe for damage. They did not inspect any of these and told me so. Yet, their paperwork stated they did a 21 point inspection. They told me all that was is checking codes. The dealership is now claiming the car is repaired, without those concerns inspected, and neither my wife nor I feel safe taking the VIN back.

I am submitting this complaint regarding ongoing and persistent mechanical issues with my vehicle since the time of purchase. The vehicle has repeatedly shut off unexpectedly, creating a serious safety concern. Initially, I suspected the issue might be related to the battery, and I have replaced the battery twice within the past 4 years. However, the problem has continued. In January, the vehicle began shaking and shutting down again. I took it to a mechanic, who diagnosed the issue as faulty spark plugs and an ignition coil. The diagnostic codes provided were P0303 and P0456, and the recommended repairs were completed. Approximately one month later, the vehicle began shutting off again. I then took it to the dealership, where I was advised that the valve cover gasket needed to be replaced, along with the belts, and that a fuel system cleaning was required. I subsequently had these repairs completed by my mechanic. Less than a week after completing those repairs, the vehicle once again began shutting down. A diagnostic scan then produced code P123300. In addition to these repeated shutdowns, the vehicle consumes an excessive amount of oil, has poor acceleration, and continues to stall unexpectedly both while driving on the road and while idling, such as in a drive thru. These recurring issues have made the vehicle unreliable and unsafe. I am concerned about the risk of the vehicle shutting off while in motion, which could lead to a dangerous situation. I am requesting that this matter be reviewed for potential defects or safety-related concerns.

The contact owns a 2025 Kia Telluride. The contact received notification of NHTSA Campaign Number: 26V105000 (Seats). The local dealer was contacted. The contact called another dealer, Gunter Kia (1900 S State Rd 7, Fort Lauderdale, FL 33317); and was informed that the part for the recall repair was on back-order. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

On December 24, 2025, while driving in traffic, my Kia Sportage experienced severe lurching, bucking, and jerking, causing the engine to shut down. All dashboard warning lights illuminated, including a message prompting me to "turn engine back on." The vehicle would not restart, necessitating a tow to Horne Kia. After several days of diagnostics, it was determined that a blown ignition fuse and a bad fuel pump relay were the issues, along with a battery replacement. However, just 19 days later, while attempting to merge onto the freeway, the vehicle again bucked violently, and the engine shut down with all warning lights flashing. The police had to assist in moving my vehicle out of traffic, and it was towed to Courtesy Kia in Mesa, AZ. Once again, no error codes were found. After further diagnostics, it was discovered that the same ignition fuse had blown and that the catalytic converter had "shattered." The catalytic converter was replaced. Upon picking up the vehicle from the dealership, and driving less then 5 miles on freeway, the vehicle was bucking and hard shifting once again resulting in a third tow to dealership just 48 hours later after the previous service. The dealership ran several diagnostics under Kia's tech line, which revealed that the engine pistons are slipping and not functioning properly, resulting in loss of compression. Per Kia's tech line, a new engine long block was ordered and replaced.

February 23 2026: Discoverd the rear window had imploded on its own overnight. investigated with the neighbor's Ring camera to see if there was suspicious activity overnight and found there was none. I had the glass replaced. I thought this was bizarre to have a window implode but didn't think anything else. March 17, 2026: Driving home from an errand the rear window imploded again with the most impressive sound-like a gunshot- and the window bits sprayed inside the vehicle. The sound was so loud my ears rang for approx 2 hours afterwards. I have the repair people coming out again, but am working with the local Kia Dealership to source the reason for the issue. This is no longer a one-off problem, but a particular car defect. There have been no warnings or extreme weather temperature changes that could factor into the problem. The incidents are sudden and without warning or reason. I have photographs from both incidents.

Driving car and then all of the sudden a critical battery alarm appeared and I lost the ability to go above 23 mph. It ended up being the ICCU that needed to be replaced.
