KIA Complaints

Kia Case #[XXX] Dear NHTSA, I am filing a formal complaint against Kia America, Inc. regarding their failure to resolve a serious safety issue with my 2016 Kia Sorento. Kia confirmed my engine failure was covered under recall due to a known manufacturing defect, yet my vehicle has remained unrepaired at Allentown Kia for over four months, with no resolution from Kia corporate. Incident Details: On [XXX], while driving on [XXX] between Lehigh Valley and Philadelphia with my young son, my engine seized without warning, leaving us stranded in heavy traffic, creating a severe safety hazard. My car exhibited no warning lights or issues beforehand. This issue stems from a known defect affecting the connecting rod bearings, which can lead to engine seizure, stalling, or even fire—a defect Kia has already acknowledged under a class-action settlement. Kia’s Negligence & Ongoing Harm: Despite multiple efforts to seek resolution, Kia has failed to act: Over 15 calls to Kia customer service with no resolution. Multiple visits to Allentown Kia with no repair timeline. Multiple written complaints ignored by Kia corporate. Still paying my car loan for a vehicle I cannot use. No loaner vehicle or reimbursement for transportation costs. Severe emotional distress, especially for my wife, who struggles with anxiety and depression. Requested Action: I demand immediate action to hold Kia accountable: A definitive resolution—either a full repair or replacement of my vehicle. Immediate provision of a loaner vehicle or reimbursement for transportation costs. Financial compensation for ongoing loan payments on an unusable vehicle. Agency Action Request: I urge the NHTSA to: Investigate Kia’s mishandling of Recall Case #[XXX]. Hold Kia accountable for failing to prioritize consumer safety. Ensure Kia provides a resolution within a reasonable timeframe. Supporting Documentation: I have attached records of my communications with Kia corporate and the dealership, al INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

In a car accident I got into, my car’s airbags did not deploy like they should have and therefore I got greater injuries than I should have. I believe I hit the steering wheel and I did hurt my chest. Both my elbows were sore as well and as well as both my knees had big bruises on them. My right knee to this day still has a bruise/mark on it, which still does not feel the same since then. Very soon after my claims adjuster actually found out there was a recall on a huge amount of Kia’s because of their airbags not deploying and some type of electrical wiring not working properly or something that has to do with that. However, my year car (2019) was not included in this recall. But as you can see, it should have been. My car got totaled as a result from this accident and I did end up going to the hospital afterwards to get checked out. About two weeks or so before, my car just passed its yearly car inspection. And no, there were no messages or other symptoms of the problem prior to this all.

The contact owns a 2016 Kia Soul. The contact stated that while driving 55 MPH, the vehicle shut off after the engine became hot. The engine and oil lights were illuminated. The vehicle failed to restart. The contact stated that the failure was related to NHTSA Campaign Number: 19V120000 (Engine, Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed and determined that the Oxygen sensor needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken to an independent mechanic who determined that the catalytic converters needed to be replaced. Additionally, there was oil leaking from the vehicle. The DTC displayed was P0240. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 11,322.

I took my 2022 Wind AWD EV6 into Bob Johnson Kia for the required SC327 recall service on Feb 17. I was informed that the service would not be performed because they were having too many problems with critical failures after performing the service on other cars. Specifically, they said they had 7 EV6s that died within weeks of performing the SC327 update, 4 of which were still in their back lot waiting for new ICCU assemblies. They recommended to wait until Kia sorted out the quality issues surrounding the SC327 update. This seems highly suspicious since it's a required recall service. I'm aware that Kia has a design problem with the ICCU and has mishandled service support from the beginning, but I need to understand my course of action and how you recommend I handle this situation.

The contact owns a 2020 Kia Optima. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, and the vehicle was connected to a diagnostic machine. The DTC indicated a glow relay failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 118,000.

What happened? While driving my 2025 KIA Niro on [XXX] , I stopped at a red light behind another vehicle. Suddenly, my car was rear-ended by another vehicle, causing a significant impact that pushed my car forward into the vehicle in front. The seat belts deployed but I sustained a broken nose from hitting the steering wheel. My daughter and I were taken to the hospital for treatment. Component or System that Failed or Malfunctioned: The floor wiring assembly beneath the front passenger seat, which may have prevented the front airbags and seat belts from deploying properly, and could have caused an unintended side curtain airbag deployment. The vehicle is available for inspection upon request. Safety Risk: The malfunction posed a serious safety risk as the airbags and seat belts may not have functioned as intended, increasing the risk of injury in the event of a crash. Reproduction of the Problem: The problem has not been reproduced or confirmed by a dealer or independent service center yet. Inspections: The vehicle has been inspected by the police and insurance representatives after the accident. Warning Lamps, Messages or Symptoms: There were no warning lamps, messages, or other symptoms of the problem prior to the failure. Best Assessment of Incident and Cause: The recall notice issued by KIA indicates that the floor wiring assembly beneath the front passenger seat may become damaged, which can prevent the front airbags and seat belts from deploying properly or cause an unintended side curtain airbag deployment.

The car continues to burn oil and have to put oil in it although not time for oil change. I took the vehicle to dealership several times because whenever I get gas it won’t let me start it right away or stutters after getting gas. Whenever the car is in park or idle it’s making a knocking noise and shaking really bad. The check engine light keeps going off and on but this most recent time it is not on. Initially i was advised they could only diagnose when check engine light on but that’s the issue because light does not stay on. I was on the freeway going about 70mph the car started declining in speed so had to hurry and pull over. Pulled over and turned off the car then it took several times to start back up. Vehicle currently at dealership waiting for more info but said it’s something related to the engine misfire.

I have had my cat. Replaced and in 6 months it's clogged again. My car has no dash lights alerting for a problem but my cat. Keeps getting ruined and oil turns really black after having oil change done in a week. I'm unable to drive car it stalls out now that the cat. Is not working correctly. When it stalled out the first time was on freeway.

The front and rear passenger side windows of my 2025 Kia Sorento intermittently fail to operate. When attempting to roll them down, all that can be heard is a clicking sound, and the windows do not move. This issue occurs randomly and without warning. The malfunction poses a safety concern, as functioning windows are necessary for proper ventilation, emergency egress, and communication with others outside the vehicle, including law enforcement or toll booth operators. The issue was first reported to Kia of Bowie on December 9, 2024. However, the dealership stated they could not recreate the problem and, therefore, could not make repairs, citing that Kia would not reimburse them unless they could verify the defect. I was advised to record a video of the issue should it occur again. The problem has persisted multiple times, but due to being the driver, capturing a video was difficult. I was recently able to record the malfunction, showing both windows failing to operate with only the clicking sound audible. On February 17, 2025, I returned to the dealership with a scheduled appointment to address this issue. After waiting 2.5 hours, I was informed that they again could not recreate the issue and that my video evidence was not considered sufficient for a repair. Despite following the dealership's instructions, no resolution has been provided. Additionally, my Kia Connect system is not functioning properly, and the radio sound intermittently cuts in and out. These electrical issues raise concerns about potential broader system malfunctions that could compromise vehicle safety. No warning lights or error messages have appeared related to these issues. The vehicle remains available for inspection upon request.

Low beam head lights visibility maybe reaches 3-4 feet infront of car at max. Have upgraded bulbs twice to higher lumens but still must run hibeams at night. I drive mountain passes daily and must use hi beams, not safe for oncoming traffic.
