KIA Complaints

Recently our 2021 Kia Telluride, had a fluttering/metal knocking/mechanical sound and I scheduled a shop visit at our trusted local mechanic. After their inspection, they found that the oil was extremely low and there was metal shavings in the oil filter housing. This was found when absolutely no warning lights were activated that would indicate low oil level or any other engine challenges. The vehicle is maintained with regular oil changes. The vehicle only has 65k miles. Looking further into this online, it seems very similar to the Theta engine recall from Kia. No warning lights/indicator lights, well maintained vehicle with regular oil changes, and to all of a sudden consume almost all the oil and have metal shavings in the oil filter housing is extremely concerning. As of 4/6/2026 the dealer is assessing the vehicle and coming up with a plan and or further actions to be done.

I've never had a problem staying awake driving. I don't have this problem in my vehicles or other vehicles. Every time I drove the car. I could not stay awake. I ve driven the car about 5xs. I would fall asleep and not even realize it. Now fell asleep driving the car two nights ago. No warnings went off and I drove over one lane and off into the center medium. No lane change warnings went off. But I truly believe there's something more going on with the car that's making people fall asleep. My neighbor rode with me to the store in it (14 miles ) she was falling asleep. She wasn't one bit tired when we left my house. Once we got out of the car and we're changing the oil on it, we walked over to the store a couple blocks away. We were fine. Got back in the car. Started driving it home and both of us were falling asleep. There was something wrong with this car

The sunroof mechanism in the vehicle jammed and broke out of the track. When my wife drove the vehicle in the interstate the sunroof began to vibrate and move around. She was afraid the glass was about to fly out and possibly hit a vehicle behind her. She had to reduce her speed excessively and my daughter had to hold on to the sunroof all the way home. The vehicle is well maintained with approx 50.000 miles. The warranty is out and I am being told that KIA will not cover the repairs. I am still trying to get customer affairs to approve a fully covered repair at no cost but it seems the are not being co operative so far.

I respectfully request that NHTSA review this issue for potential safety related defect trends involving excessive oil consumption that progress to catastrophic engine failure in 2020 Kia Sportages equipped with the 2.4L engine. The vehicle consumed oil at an abnormal rate between oil changes despite routine maintenance and regular oil level checks, and the condition ultimately resulted in a non-operational vehicle. Over the months leading up to the failure, I was forced to add oil at least monthly and began checking the oil level more frequently due to the rate of loss. I maintain my vehicle carefully and have consistently kept up with oil changes. In March 2026, the vehicle broke down after I experienced a sudden loss of power and stalling, and the engine ultimately failed and left the vehicle non-operational. When an engine consumes oil rapidly and then stalls or loses power unexpectedly, drivers can face an increased risk of a crash particularly if the failure occurs at highway speeds or in traffic. I have found numerous similar complaints posted online by other Kia owners describing the same pattern of excessive oil consumption followed by sudden loss of power, stalling, and/or engine failure. While I understand online posts are not formal findings, the volume and consistency of these reports suggest a broader trend that warrants NHTSA review for potential defects and safety impacts. After the failure, I had the vehicle towed to Kia of [XXX] . The service department advised that the engine requires replacement and quoted approximately $14,000 for the repair. The invoice I received (#XXX) states that the technician recommends “short block motor replacement,” but the dealership verbally stated they would not perform only a short block replacement and would instead replace the complete engine because, in their view, a short block-only repair would lead to additional problems.

Vehicle charging. When charging at home or public charging stations. It sometimes automatically shuts off before it gets to limit set.

Shift arm gear stuck- unable to shift from park to drive to neutral, reverse, etc.

I am filing a complaint regarding a 2021 Kia Sportage that experienced catastrophic engine failure, leaving the vehicle non-drivable despite regular maintenance and documented oil changes. I brought the vehicle to an authorized Kia dealership, located at 402 NJ-35, Keyport, NJ 07735, for evaluation. On or about March 17, 2026, I was informed by the dealership that coverage for engine replacement had been denied. At that time, I was not provided with a clear or sufficient explanation for the denial. Due to the lack of explanation and assistance, I escalated the matter to Kia corporate and was assigned a case manager. On March 30, 2026, I was contacted by my assigned case worker from Kia corporate, Marcia, who confirmed that my request for engine replacement remained denied. Again, no specific or sufficient explanation for the denial was provided, despite my attempts to obtain clarification. I made multiple efforts to understand the reason for the denial and to resolve the issue directly with both the dealership and Kia corporate. Despite these efforts, I was not offered a reasonable solution, nor was meaningful assistance provided. The vehicle ultimately stalled out in the middle of a highway. As a result, I am now left with a non-drivable vehicle and a significant financial burden, including an outstanding loan balance on a vehicle that cannot be used. I am also aware that there have been reported concerns, recalls, and investigations involving engine issues in certain Kia vehicles. While I understand each case is reviewed individually, this raises concern that my situation may not be an isolated incident and warrants further review. I believe this outcome is unfair given my documented maintenance history and the severity of the engine failure. I am requesting assistance in obtaining a fair resolution, including reconsideration of the denial and/or financial assistance toward the cost of engine replacement.

Due to soy-insulated wiring used in wiring harnesses, rodents are attracted to the wiring components in the engine bay. Even using deterrents doesn't see to affect them. What started as a simple check engine light for what was assumed to be a faulty sensor turned into a total wiring harness replacement. Without knowing that the wiring provided an added risk to damage from external factors, there was no need to check any of the wiring. If the check engine light didn't come on, it was possible that total power loss to the vehicle could've occurred at any time, due to the various wires damaged by the rodents. We were driving on the freeway at the time when the initial check engine light came on, and a loss of power while going 65 mph could've been devastating to both our family and other drivers on the road at the same time. Insurance confirmed that the cause of the wiring damage was related to the rodents being attracted to the material, and at the dealership there were at least 2 other cars needing full wiring harness replacements due to similar damage from rodents.

The contact owns a 2022 Kia Soul. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly lost motive power and stalled, with several unknown warning lights illuminated. The vehicle was unable to restart and needed to be towed. The contact received notification of NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was towed to the dealer, where it was diagnosed and it was determined that the engine had failed and needed to be replaced. The vehicle was repaired. The contact was informed by the dealer that a used engine was installed as a replacement in the vehicle. The manufacturer was made aware of the failure. The approximate failure mileage was 81,000.

Oil was being diluted by fuel seeping in from the injectors and the high pressure fuel pump. Vehicle was brought in twice to fix the problem. During the 24-27 Feb 26 repair the high pressure fuel pump was diagnosed and replaced. On 16 Mar 26 I noticed the oil level had risen on the dip stick (after driving ~300 miles) about 5 mm and brought the car back to the Kia dealer for diagnosis and repair. The high pressure fuel pump was diagnosed again as bad and replaced as were all four fuel injectors after they were also determined to be leaking fuel.
