2023 Kia K5

Driving down the highway and heard a pop and my seats were rising slowly and while trying to make it to the nearest exit only two minutes later my rpm’s started jumping and my engine just shut off and multiple dash lights came on. Had it towed to Kia and after they did an inspection they said that my fuel tank had expanded and was pushing on my fuel lines and pushing my back seats up. Screen shot of technician video summary sent to me by dealership down below.

I am submitting an update regarding my 2023 Kia K5 (VIN: [XXX] ). •On July 25, 2025, I delivered the vehicle to my dealership for recall-related fuel tank issues. •As of today (61 days later), the vehicle remains out of service and undrivable. •The dealership opened a Kia Techline case, confirming they are unable to repair the fuel tank issue and that it is a safety hazard. •Kia North America has not provided any resolution, despite repeated contacts and escalation of my case (Kia Claim #25408405). •I have incurred significant financial hardship, including paying the monthly car loan, maintaining minimum insurance, and paying for out-of-pocket rental expenses while Kia holds my vehicle. •I also contacted Kia Finance, and they confirmed my hardship notes are documented in their system. This situation is ongoing, with no repair performed, no reimbursement, and no safe solution provided. The recall remains unresolved, and the vehicle is unavailable for use. I request that NHTSA take immediate action to ensure Kia complies with its recall obligations and consumer safety requirements.

the vehicle failed the fuel tank Inspection recall.I have a tech line case open :Case number 25408405 . It has been 46 days since the vehicle has been at the dealership waiting for information from Kia USA . I have been still told to pay for car note that I am financing through Kia itself as well as rental because the dealership doesn’t have any loaners .

The fuel tank in my 2023 Kia K5 LXS expanded and bent the subframe. This is a known problem with K5's with the 1.5L turbo engine. Kia had an emissions campaign for this problem affecting 2021 to 2024 models. My VIN isn't in that campaign, but it had the same problem. Given the fuel tank expansion and bent subframe, my car is no longer safe to drive and has been sitting at the dealership. I was told that with the fuel tank expansion a plate could pop open and create a fire or explosion. This also caused a significant loss of power, making the car untenable to operate. Kia's Techline reviewed the findings from the dealership service department (Campbell Kia Missoula), but closed the case without offering a repair and escalated it to another department (Consumer Affairs?), where it remains unresolved after two weeks. Kia is failing to resolve the issue in the form of either a repair or a buyback and keeps dragging the case out with virtually no contact or updates. Please help. This needs resolved ASAP.

The fuel tank expanded causing the vehicle to become immobile. The car is sitting at a dealership after I declined to sign Kia's buyback so yes it available for inspection. As for my safety and other the fact a fuel tank is swelling under where people would sit and it is highly flammable/ combustible is kind of alarming to me. Yes, there are plenty of people having the same problems. The dealership has sent pictures and videos into Kia for their engineers to look over. The day before the car became immobile it was getting horrible gas mileage. There was no other things that happened no lights on the dash.

The gas tank wii not allow you to put gas in it. When you try to put gas in it won't go down in the tank hose and the fuel gauge is ready a 1/4 tank. The car jerks when pressing on the gas pedal. I have only gone around 200 miles and gauge fluctuates with different reads so you don't know exactly how much gas is in the gas tank. The engine light is on as. This is happening while I am traveling.

In June 2025, while driving my 2023 Kia K5 (VIN: [XXX] ) at highway speeds on [XXX], the fuel tank suddenly imploded. A loud bang caused the rear seats to lift, startling me and my passengers. The car lost power, and braking too hard risked leaving us stranded in fast-moving traffic. I narrowly avoided a crash while trying to maneuver us to safety. This vehicle was previously recalled by Kia in April 2024 for a fuel tank defect affecting ~236,000 vehicles. I took it to Gunther Kia in Davie, FL for inspection, and they claimed it was fixed. In March 2025, I returned to Hollywood Kia because of popping sounds and a check engine light. They diagnosed and “repaired” a purge control valve but failed to address the underlying defect. Despite these repairs, the catastrophic failure still occurred. The vehicle is now completely inoperable and irreparable. Kia later offered to buy back the vehicle but failed to respond to over 200 calls and dozens of emails from me, allowing their offer to expire without explanation. This left me paying for a vehicle I can no longer use. This defect poses a serious danger not only to me and my passengers but also to thousands of other K5 owners nationwide. I urge NHTSA to investigate Kia’s recall handling and ensure affected vehicles are properly repaired to prevent injury or death.

My 2023 Kia K5 GT (VIN: [XXX]) is experiencing a dangerous complete power loss at highway speeds. I was driving at the speed limit on [XXX] when the vehicle lost propulsion, entered limp-home mode, and illuminated every warning lamp. This has happened six times since purchase. The car is currently parked, and I am not confident enough to drive the car; I nearly missed a crash pulling into the emergency lane from the leftmost lane to the rightmost lane. After losing power in the engine, that was a traumatizing experience. I tried to explain this to people multiple times at different service centers, but they care less: "We can't fix it unless we can reproduce it," but this happens randomly; I cannot make it happen at the service center. This matches the recall SC250 symptoms exactly, though my VIN is excluded. I have tried with Multiple dealers before, but they cannot fix it. They say, "We cannot fix it unless we can reproduce it."

On Friday 5/16/25 my check engine light was on when I went to leave for work and when I began driving I felt excessive air flow coming from my back seat. I stopped and noticed that the back seat had popped up. I then noticed my gas gauge was showing empty, but my digital reading was correct.. The car was sluggish and my son's father told me that the gas tank was swollen and to stop driving it. I called Kia on Saturday morning and was told I could bring it in today at 9am. I left the car and was given a loaner, but I do not feel it would be safe to ever drive that car again. They immediately knew what the problem was and said it was a recall, but I was never notified about it. It was extremely scary driving it to Kia this morning because they are over 50 miles away from where I live.
