KIA Complaints

The contact owns a 2016 Kia Soul. The contact stated that while his wife was driving 35 MPH, the brakes became inoperable. The contact’s husband, who is an independent mechanic, inspected the vehicle and became aware that the brake fluid lines were rusted and ruptured underneath the middle of the vehicle. The contact stated that brake fluid was added but the brake pedal was mushy while depressed. The brake warning light was illuminated after the failure. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 40,000.

The contact owns a 2025 Kia Telluride. The contact stated that while driving at an undisclosed speed, there was a loud sound coming from the sunroof glass before the glass shattered. There was no impact on the sunroof glass to cause the failure. Small glass fragments fell into the second and third row seats. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 22,000.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle is a 2016 Kia Soul 1.6L GDI with approximately 83,000 miles. The vehicle experienced engine performance issues, loss of power, and stalling. A Kia dealership diagnosed a failed/melted catalytic converter and reported metal shavings in the engine oil. The vehicle has not been repaired and is available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle stalls and loses power, creating a safety hazard while driving in traffic. A sudden loss of power increases the risk of being struck by another vehicle and makes it difficult to safely maintain speed, merge, or cross intersections. Because the vehicle is unreliable and may stall unexpectedly, I do not consider it safe to operate. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The condition was confirmed by an authorized Kia dealership. The dealership diagnosed a clogged/melted catalytic converter and reported metal shavings in the engine oil. The dealership advised that the catalytic converter must be replaced before they would perform further engine diagnosis. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by an authorized Kia dealership. Kia Customer Care was notified of the issue and reviewed the claim but declined assistance. To my knowledge, the vehicle has not been inspected by a Kia field engineer, police agency, or insurance investigator. Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear? Yes. The vehicle experienced drivability issues, loss of power, and check engine light illumination. Diagnostic trouble codes reported included P0420, P2191, and P2196. The symptoms progressively worsened and eventually resulted in severe performance issues and stalling.

While driving my 2015 Kia Optima, the engine failed completely without warning. The vehicle lost power while in motion approximately 300 miles away from my home. All warning lights illuminated and the car shut down during driving conditions, creating a serious safety hazard. The vehicle was towed to a Kia dealership where it was inspected. I was informed the engine has failed and may be related to the known 2.4L engine defect and prior recall campaign involving this engine type. This vehicle has a history of multiple recalls, including engine-related recalls issued in 2018 for the same engine family. The failure occurred suddenly and without prior adequate warning, and the vehicle is now inoperable. I purchased the vehicle in May 2023, and at the time of failure it had approximately 133,000 miles. The engine began knocking loudly prior to failure, then stalled and shut off completely while driving. This incident placed me and others at risk because the vehicle lost propulsion while in traffic. I believe this may be related to a known manufacturing defect in Kia 2.4L engines that has been the subject of recall and/or investigation. I am requesting that this complaint be documented as a safety-related engine failure potentially associated with the existing recall and that it be reviewed for further investigation and manufacturer accountability

The contact owns a 2016 Kia Optima. The contact stated that while driving 10 MPH, the front driver’s and passenger’s side windows lowered unintendedly. Neither the dealer nor an independent was contacted. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The rear driver’s and passenger’s side windows were replaced, and the vehicle was repaired. The manufacturer was notified of the failure but offered no assistance since the VIN was not under recall. The failure mileage was 107,000.

The contact owns a 2016 Kia Sorento. The contact stated that after the vehicle was parked and turned off for approximately an hour, the vehicle was restarted and there was a knocking sound coming from the engine compartment. The contact continued driving and the knocking sound increasing in volume and frequency. There were no warning lights illuminated. The vehicle was taken to a certified mechanic and was diagnosed with engine failure. The contact was informed that the engine needed to be repaired. The mechanic referred the contact to the dealer for assistance. The vehicle was taken to the dealer and the contact was informed that since the vehicle was not repaired under NHTSA Campaign Number: 22V703000 (Trailer Hitches); the dealer was unable to repair the engine ffailure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 119,000.

The component that failed on my 2014 Kia Optima was the engine. Prior to the malfunction there were no lights indicating a failure. My safety was put at risk several times as my car had completely shut down on the highway going over 55 mph in way of many vehicles causing police to shut down the highway. I took the car to several auto shops to test and there was no indication of engine failure. I’ve got my battery checked, front end alignment and oil changed on schedule. The car still malfunctioned. I had it towed to the Kia dealership in March after learning about the recall on the engine. The dealership confirmed that the engine was faulty and had been recalled. There were several other recalls on that model as well. After keeping my car for a few days and charging me a service fee, they decided not to repair the engine saying that the software was not updated prior to the engine failure and they refused to repair. I was instructed to remove my car from the facility. I called their corporate office and a representative also denied my claim saying that the mileage on my car was too great. I have not been able to get in touch with anyone that can help. The car is located in a shared parking lot amongst hundreds of tenants and close to residential areas. I don’t believe it is a safe area if there is a fire risk but Kia refuses to honor their recall. The car is available for inspection upon request if needed.

The CV axel is bad and needs replaced. I am only at 72,000 miles. If I had not gotten an oil change and the technician saw it, it could have broken while driving this coming weekend for 14 hours. Independent service center is replacing. No warning. This could have caused a serious accident.

The contact owns a 2020 Kia Niro EV. The contact stated that the rearview camera intermittently failed to display an image when the vehicle was shifted into reverse. The contact stated that reverse engaged normally, and the audible alert was sounded; however, the display screen periodically remained blank. The contact stated that the failure was intermittent but had occurred several times. The contact stated that the rearview camera operated properly for a while before the failure reoccurred. The vehicle was taken to a dealer prior to the expiration of the warranty. The dealer was unable to duplicate the failure, and the vehicle was not repaired. The manufacturer was notified of the failure and suggested that the vehicle be taken for additional diagnostic tests, and the dealer would consult with technical assistance from the manufacturer to determine how to repair the vehicle. The failure mileage was approximately 11,000.

“The engine undercover (belly pan) detached and is dragging/scraping on the ground on a 2025 Kia K4 with approximately one year of normal use. The radiator support is also affected. Dealer (Selma Kia, Selma CA) denied warranty coverage and stated damage was caused by driver hitting a speed bump. These are factory-installed components on a one-year-old vehicle and should not detach under normal driving conditions. This appears to be a fitment or installation defect.”
