KIA Complaints

The contact owns a 2017 Kia Optima. The contact stated that while driving approximately 50 MPH, there was an abnormal knocking sound coming from the engine compartment. The contact stated that the check engine and oil warning lights illuminated and then turned off independently. The contact slowed down, and after arriving at the destination, the vehicle was towed to an independent mechanic. The contact was advised by the mechanic that there was potential engine failure and was referred to the dealer for assistance. The vehicle was towed to a dealer, and the contact was made aware that the VIN was included in NHTSA Campaign Number: 21V844000 (Engine); however, the KSDS software update was not performed prior to the engine failure, which disqualified the vehicle from the engine replacement. The vehicle was not repaired. The manufacturer was informed of the failure and advised the contact that the vehicle did not qualify for the engine replacement. The failure mileage was approximately 64,500.

Description of Crash: On [XXX], I was involved in a front-end collision while driving my 2024 Kia Sportage. Despite the impact, the airbags did not deploy. Additionally, the Forward Collision Assistance system did not engage or warn me prior to the crash, even though conditions were normal and the system was active. Safety Concern: •The airbags and collision assistance are federally regulated safety systems. Their failure put me and any potential passengers at serious risk. •I am very concerned this indicates a defect in the airbag and/or collision avoidance system. Damage/Injuries: My front end of my vehicle is completely destroyed, and so is my engine. As for myself I am experiencing some soreness and discomfort Requested Action: •I request that Kia and NHTSA investigate this failure as a potential safety defect. •I want confirmation that my case has been documented and reviewed for possible recall or repair action.

On Sunday, [XXX], I was driving my 2020 Kia Sportage on [XXX] in California at approximately 75 miles per hour. Without warning, the engine made a loud, abnormal noise and the vehicle suddenly and dangerously lost power. My speed dropped abruptly to around 62 miles per hour, nearly causing a rear-end collision as surrounding vehicles were traveling at freeway speed. I was forced to immediately pull over to the shoulder to avoid being struck. At that point, the engine was running extremely hot, creating a hazardous situation. Out of concern for my safety, and with fear that the vehicle could potentially catch fire, I exited the vehicle and waited at a safe distance until I could arrange for a tow truck. This incident placed me and other motorists in serious danger. The abrupt loss of power at freeway speed could have easily resulted in a major accident. It is important to note that this Sportage has been meticulously maintained, with 12 documented service records in just 2.5 years of ownership. This clearly demonstrates proper care and maintenance, ruling out negligence as a cause of the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Prior to the below incident, my vehicle was driving normally. Oil levels were normal, and there were no warning lights. In June 2025, I was driving on [XXX] during morning rush hour. As I approached a traffic light at the end of this 3-lane expressway, the engine suddenly stalled. I rolled up to the red light. When safe to do so, I left the vehicle to stand on the side of the road so as not to get hit. I had the car towed to a local repair facility. Repair shop looked at the vehicle and determined that the engine was seized. They then checked for TSB's and discovered that Kia had, in some instances, extended the warranty to 180,000 miles and 15 years. My vehicle had 142,000 miles. I then had my car towed to the closest Kia dealer in Hickory, NC. The dealer initially indicated it was possible my car would be covered by the extended warranty, but they needed to run pressure tests to determine the cause of the engine seizure. Over the next 2 weeks, I called the dealer repeatedly, but they had no update for me. After about 2 weeks, they told me that my vehicle would not be covered by the extended warranty, and a new engine would cost me $15,000. I then called Kia Customer Care, and the representative told me there was nothing they could do. I asked about an appeals process and was told there is none. After I returned from vacation in early August, the Kia dealer contacted me and requested that I pick up my vehicle. I drove to the dealer and called a tow truck to bring it to my home. I rented cars at my own expense from the time of the engine failure until I bought a new car in mid-August. Shortly thereafter, I arranged to sell the Kia to a used car dealer for $1,500, far less than I would have received with a healthy engine. At that point, I needed to get the car out of my garage. While cleaning out the car the night before it was to be picked up, I opened the hood and found that the engine had been left disassembled with parts lying all over the place.

Since April I have been having the same issue. Sometimes when I am stopped and the autostop is supposed to shut down the engine, the engine just sputters and if I hit the gas nothing happens. I have to put the car in park and shut it down then restart it. I try to shut the auto stop off when I get in the car but sometimes I forget. It has happened at over 20 times that I have documented over the last couple of thousand miles, many times in dangerous locations, in the middle of interactions or waiting for a light. The engine light has also gone on and off over the last couple of months. The car is now at the dealership and they say the high pressure fuel pump is leaking. I see there has been a recall in specific Kia Stingers, should my car be involved in this recall? The issue began around 45000 miles and continues at 52000.

Oil is burning too fast... Car has had an issue like this in the past and the problem resulted in a blown engine... Re-call was found by dealer and honored and endinge re-placed.. Car is now expierenceing this problem again... Second, steering wheel is locking when turnning fully left... Third, car smells extremely strong like gasoline when car is warming up...

I was driving down the highway at 65 mph when suddenly the sunroof exploded in an outward fashion causing me to pull over. I believe there is a defect in the sunroofs of 2011 to 2014 models. I've contacted Kia. They refused to cover it. Nothing hit the windshield. It just spontaneously exploded.

February 2024 (27,813 mi): Vehicle lost acceleration while driving, would not transition from EV to engine mode, entered limp mode. Dealer replaced high-pressure fuel pump under warranty after consulting Kia Tech Line (case #[XXX]). September 2025 (58,000 mi): Vehicle will not start without manually resetting 12v battery module integrated in hybrid battery system. Pattern suggests hybrid control system defects, not resolved by previous repair. Car has now been with dealer for 4+ days figuring out this issue.

I am reporting a serious safety concern regarding the 2025 Kia Niro Hybrid and its adaptive cruise control system. When the cruise control is activated and set to maintain a certain speed, the vehicle continues at that speed regardless of whether there are other vehicles in front of it. In multiple instances, the car approached slower-moving vehicles at 45 mph without reducing speed or giving any warnings. There was no automatic braking or even a prompt to alert the driver of the imminent danger. This is extremely dangerous and could easily result in a rear-end collision if the driver is not fully alert. It is especially surprising because the same vehicle features intelligent climate control functions—such as adjusting fan speed during phone calls and preventing windshield washer fluid odors from entering the cabin while the A/C is running. Given the level of attention to such minor details, the lack of basic forward collision mitigation behavior is unacceptable. The issue was reported to a Kia service center, but no clear explanation or resolution was provided. I believe this may be a software bug or a design oversight that has not been properly acknowledged. Recommendation to other drivers: always keep your eyes on the road and be ready to intervene, even if the adaptive cruise system is engaged. The risk of collision is high if you rely on the system to slow down for vehicles ahead. This needs to be investigated immediately before it leads to serious accidents. I urge the NHTSA to review this issue and, if necessary, request a recall or software update from the manufacturer.
