FORWARD COLLISION AVOIDANCE: WARNINGS, BACK OVER PREVENTION: WARNINGS, FUEL/PROPULSION SYSTEM
Check engine light came on and when filling up my gas tank, gas spit back out at me which has happened with the fuel tank i had in it last year and has since been replaced. Forward collision, EBS, traction control and forward safety sensor lights came on the next day and the car is running extremely rough. It was towed to a shop to see if it has to do with the fuel tank recall. Multiple people in Roanoke, Virginia are having the exact same problem as is a large portion of people online complaining about the exact same thing. Some going back 30 weeks ago.

FUEL/PROPULSION SYSTEM
July 5th we were driving heard a loud boom and the car slowed down we pulled over. Then we seen that the seat was lifted up and smelled gas. We had an appointment for Monday July 7 for this recall and wasn’t able to drop off the next on Tuesday July 8. As called that Monday made the dealer aware. Now they been having the car and we are just waiting on the next process. There’s not sure what saying Kia will contact us. I am reaching out to get some type of results. We can’t get a rental car and next week it will be 30 days on the 8th of August. We are looking to resolve this matter with Kia.

UNKNOWN OR OTHER
I am submitting this complaint regarding ongoing and unresolved safety issues with my Kia K5, which I believe are directly related to a known recall involving the ECM (engine control module) and/or fuel system. My vehicle continues to jerk and misfire during acceleration, and it has even stalled at idle on multiple occasions — creating a serious safety concern for myself and others on the road. I have already completed the recommended repairs, including new ignition coils and spark plugs, yet the problem persists. Despite these symptoms aligning with known recall-related issues, Kia of Orange Park (Florida) has refused to fully diagnose or investigate the matter, citing that the recall does not apply in my case. However, the symptoms match those outlined in other ECM/fuel system-related recalls, and this is not the first time this dealership has failed to properly address mechanical concerns. Previously, I had to escalate an A/C issue to Kia Corporate, which only resulted in a resolution after a recall was issued right before my vehicle was set to be returned with the same issue. That situation makes me extremely concerned that my current safety concerns are again being ignored and will only be addressed after a broader recall is issued. I am requesting that the NHTSA investigate this matter, as I am worried this defect may affect other vehicles and poses a safety risk that Kia and its dealerships are not taking seriously. Thank you for your attention and action.

ENGINE, FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: RADAR
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.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
My fuel tank expanded while I was driving on the highway, causing my car to stall and would not respond to me pushing on the gas. I pulled over on the side of the highway and looked back and saw my rear seats were pushed up. Got it towed to the Kia dealership and they informed me that my car was totaled because the gas tank expanded so much it bent my frame. This has been an ongoing issue with Kia/Hyundai vehicles but they have still not issued a formal recall, only a voluntary callback even though this is a very dangerous defect.

Air/hearing works intermittently. I’ve had fuses replaced and this seems to be a known and ongoing issue that Kia refuses to acknowledge. Many have reported that the wires are melting inside of the fuse box and I fear that this may result in a fire.

FUEL/PROPULSION SYSTEM, SEATS, UNKNOWN OR OTHER
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.

I was driving down the highway when I heard a loud explosion like a gunshot that caused me to slow down and almost getting into an accident. It was scary; I came to a stop and realized that my sunroof had exploded. There is a large hole in my sunroof bigger than a watermelon with glass particles everywhere.

STRUCTURE:BODY
Component or System: Front sunroof glass – panoramic sunroof system The sunroof has been removed but I could provide pictures What happened: While my vehicle was parked, the front sunroof glass panel spontaneously exploded outward, sending shattered glass fragments upward and outward. There was no external impact, object, or weather condition that could have caused this. The sunshade was closed, which fortunately prevented the glass from falling into the cabin. Had the shade been open, I or any occupant would have been at serious risk of injury. How safety was compromised: This is a serious vehicle safety defect. Spontaneous sunroof explosion could have caused glass-related injury to occupants, or road hazards to nearby vehicles or pedestrians if this had occurred while driving. The vehicle is currently unsafe to drive, especially in bad weather, due to a gaping opening in the roof. Inspection/confirmation by service center: Yes – the vehicle was inspected by two authorized Kia service centers. Both confirmed the glass was blown outward, not due to any external force. The second service center provided a quote to replace only the glass, not the entire sunroof system, indicating it was a glass failure. Inspection by manufacturer/insurance/police: Kia America has not physically inspected the vehicle and refused to request a statement from the service center, even after I submitted photographic evidence and a recording where the service manager agreed with my explanation. The vehicle was not inspected by police. My insurance was notified, but I am attempting to resolve this under warranty due to the nature of the defect. Warning messages or symptoms before failure: There were no warning lights, sounds, messages, or cracks leading up to the incident. The glass exploded without warning, which is why this poses a critical safety concern. Best assessment of cause: I believe this was a structural defect in the sunroof glass or a manufacturing/design flaw. I’v

AIR BAGS, STRUCTURE:BODY
I am the owner of a 2025 Kia K5 GT-Line that was recently involved in an accident. In the days prior to the crash, I experienced recurring issues including screen reboots while driving and temporary power loss. I do not remember the moment of the accident, and I am currently under medical care for head trauma. I am reporting this because I believe the vehicle may have malfunctioned in a way that contributed to the accident. Please advise if there are known issues with the 2025 K5 GT-Line, and how I can formally report this case for technical investigation.

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
While driving the car started to have the sensors for the adaptive cruise control, automatic emergency breaking, blind spot warning, forward collision warning, and rear cross traffic warning all came on. The rpm starting going crazy the car was shaking and struggling to start, the car was shifting weird causing the acceleration to be poor. This all happened while driving if we were on a busy road we would’ve gotten hit the car randomly started breaking and slowing down, this is dangerously and could cause serious injury and damages to the vehicle and others around it. This is a problem a lot of people have been complaining about and need to be fixed it’s not okay or safe to be driving a car with these issues especially when there is no warning it just breaks and shuts down no matter where you are or how fast you may be going.
