KIA Complaints

Engine started making rattling sounds during startup and when accelerating. Kia dealer said the engine failed and needed replaced. Repair cost were around $9000.00.

The contact owns a 2025 Kia Sorento Hybrid. The contact stated that while driving 60 MPH, the vehicle lost motive power. The message "Check Fluids. Fluids Are Low" was displayed. The contact stated that the vehicle was able to restart but failed to respond upon depressing the accelerator pedal. The vehicle was towed to a dealer, where it was diagnosed that an inverter coolant component had sustained a hole from a pebble or a bug, causing the coolant leak. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 2,000.

While driving, the sunroof on my 2025 Kia Telluride exploded. I had the it closed, so at first I didn't know what had happened. It sounded like I was shot. I was not able to pull over right away due to traffic. However, I heard the glass and figured out what had happened. Nothing struck my car. When I was able to get out and look at it, the glass was protruding outwards and a huge hole was left in the middle of the sunroof (almost as big as the sunroof). This was terrifying. It could have caused a wreck, easily. I immediately hit my breaks and the car behind me swerved. I had to think fast and tell myself to just keep driving because I couldn't pull over safely. I have not had the vehicle 7 months and thought this would not be a problem to get fixed because it is clearly not a normal, or natural occurance. At first, they gave me a loaner and said it would be fixed. Then, they said it could not be covered by warranty and to come pick it up and return the loaner. When, I got there I asked to speak to the manager and he was very sympathetic. He said he would work on getting it paid for and let me take the loaner back home. I am still waiting to hear from them. However, the internet tells me this is a recurring problem. Therefore, I wanted to fill out this form so that the NHTSA is aware of this issue.

While driving my 2017 Kia Optima (Theta II engine) at approximately 115,900 miles, I suddenly experienced engine failure. The vehicle began to stall and produced a burning smell shortly before the engine seized completely. I had the car towed to a Kia dealership, which confirmed an internal engine failure and noted that there were no signs of external oil leaks or neglect. The failure occurred only 4,500 miles after my last oil change, which was documented and professionally completed. The Kia technician mentioned verbally that this was due to excessive oil consumption and burning — an issue I later found to be widely reported in other Kia vehicles using this engine type. The estimated repair cost is over $14,000, which is more than the value of the vehicle. Despite my warranty being expired, this type of failure appears consistent with known manufacturing defects. I am reporting this for public safety and accountability. The vehicle failed without warning and could have caused a dangerous situation on the road.

The contact owns a 2015 Kia Optima. The contact stated while the contact's wife was driving at an undisclosed speed, the vehicle made an abnormal ticking sound. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where the contact was informed that the failure could be related to the engine. The vehicle was then taken to the dealer, where it was diagnosed that the engine had failed. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the VIN was included in an unknown related engine recall; however, the engine repair or replacement was not covered under warranty due to missing service documents. The failure mileage was approximately 78,000.

Component/system failed: Engine and Power Train. Available for inspection: Yes, the vehicle is currently at the dealership. After a loud ticking/knocking noise from the engine began, the car lost power while driving. It matches symptoms associated with Kia’s known connecting rod bearing failure issue (covered under Recall SC176 and Campaign PI2002A). There were no warning lamps at first, but later the oil pressure warning light began to flash intermittently. A Kia dealership confirmed the issue and completed the PI2002A ECU update. However, they denied the extended engine warranty coverage under the campaign, saying that the vehicle was purchased at an auction, even though this issue stems from a known manufacturing defect and recall that should apply to the vehicle, regardless of ownership history. This creates a serious safety concern, as the engine could seize while driving. This issue has been reproduced and confirmed by the dealership and documented under Kia Case #25414628 and #25331856. This denial contradicts the campaign terms and puts drivers and others at risk.

I was driving down the highway when the sunroof randomly exploded, there was no debris that hit the roof or damages to the roof prior.

While driving my 2015 Kia Optima, the engine suddenly failed without warning. I noticed a loss of power, and shortly after, the oil pressure warning light illuminated. Upon pulling over safely, I discovered that the engine had drained all of its oil, despite recent maintenance. There were no prior warning signs or leaks visible. This posed a serious safety risk as the failure occurred in the midst of traffic. The vehicle had approximately 75,885 miles at the time. A mechanic later confirmed catastrophic engine failure due to oil starvation. This issue appears to be consistent with known engine defects in similar Kia models.

On our way to Florida, our car broke down on the highway. When we were able to get our car towed to a mechanic, the mechanic stated that the issue was a rod bearing went out which matches the kia recall reasons for the same vehicle as ours. We took the car to Kia and they tested it and the rod bearing was the issue. We had no warning lights prior to our car breaking down and it was taken for an oil change just 5 days before. See below for more info on the recall: The 2016 Kia Soul, specifically models with the 1.6L GDI engine, was included in a Kia product improvement campaign related to connecting rod bearing wear. This campaign involved a software update for the Engine Control Unit (ECU) to implement a Knock Sensor Detection System (KSDS). The KSDS is designed to detect early signs of bearing wear and alert the driver via a blinking Malfunction Indicator Lamp (MIL) and Limp Home Mode. This prevents severe engine damage, including potential engine failure. Some 2016 Kia Souls with the 1.6L GDI engine experienced excessive connecting rod bearing wear, potentially leading to engine damage.

Excessive oil burning Burns an insane amount of oil every week, 2-3 quarts of oil has to be added every week. Started noticing slightly low oil a year ago wasn’t a lot but it has gotten worse.
