2023 KIA K5 Complaints

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.

While driving at about 70 MPH the right rear tire locked up temporarily causing loss of control of the vehicle. Luckily there were not other cars around as the car was in 3 lanes prior to coming to a complete stop. If this happened in traffic it could have caused a significant accident. There were no warning lamps on dash before or after the incident. After inspecting vehicle on side of road I could not see any issues. Drove about 15 yards and heard a grinding noise. Vehicle was towed to dealership. Dealership has inspected vehicle and advised it was caused by a failed awd coupler. The repair will be covered by warranty.

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 .

I started the purchase process of a Kia in 2022 of July. The car was built with a faulty fuel tank and no recalls were made on the vehicle. June 27,2025 I was driving on the freeway when my car started to not accelerate my fuel tank ejected into my backseat and I was forced to jump out of my car on the freeway.

My engine line keeps returning regardless of the multiple visits to the service department in attempt to fix recall complications at BONIFACE-HIERS KIA. Today will be the fourth visit for fuel tank and ECM recall related malfunctions.

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.

After getting my rearview mirror, repaired by the Kia dealership when I break when I came to a stop, my car started flashing forward, collision warnings, and Blindspot assist warnings and activated the emergency parking break ticket to the Kia dealership they saw the safety issues in in diagnostics and a history of it They said they won't replace anything unless it happens in the dealership's care gave the car back to me and less than five minutes after leaving the same issue occurred. They've currently had my car two weeks and have no update on what's going on was almost in an accident because of this issue after getting it back from the dealership. I also have a recording of the dealership stash. They won't do anything about it unless it happens in their care. With them, knowing it's a safety issue.

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 contact owns a 2023 Kia K5. The contact stated that upon purchasing the vehicle new and driving off the dealer lot, the message "Radar Sensor Blocked" was displayed. The dealer was informed but no assistance was provided. The vehicle was driven to the residence. The contact stated that another message indicating that a sensor was blocked was displayed, and the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine had imploded. The vehicle was not repaired. The manufacturer was notified of the failure and a case was filed. The manufacturer offered buyback assistance; however, the dealer had not returned the owner’s or the manufacturer’s calls. The failure mileage was approximately 74.

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.
