NHTSA complaint #11723003 — an unverified report by a vehicle owner.

2023 KIA K5 Detroit, MI

STRUCTURE:BODY

My 2023 Kia K5 experienced a fuel system issue related to Recall SC288 (Fuel Tank Inspection & ECM Update). The vehicle displayed a check engine light and could not accept fuel while refueling. The vehicle was taken to a Kia dealership on May 21, 2025 where the recall inspection failed. The repair order states the fuel tank swelled and damaged the body of the vehicle. Kia opened a Techline case and retained possession of the vehicle. Kia has now acknowledged the vehicle is not repairable. The vehicle has been in Kia’s possession since May 2025. This situation resulted in extended loss of use and financial hardship.

2025 KIA K5 North Tonawanda, NY Crash

STRUCTURE:BODY

The car material itself is very cheap meaning it poor quality, very flimsy, I hit a curb and the grill and cover just broke so easily even though it was now a serious hit but very small and slight to the point where you can’t feel it. Now it’s just hanging off and shaking badly because of the poor material, it isn’t stuff enough to keep in place.

NHTSA complaint #11696397 — an unverified report by a vehicle owner.

2021 KIA K5 Cypress, TX

STRUCTURE:BODY

While driving, the check engine light came on. Soon after, the rear floor of my 2021 Kia K5 lifted upward, and I noticed the fuel tank underneath had swollen. When I opened the gas cap, it blew off with force and gasoline sprayed on me, soaking my clothes. This could have caused a fire or explosion. The car is now unsafe to drive, and the rear seat cannot be used because the floor is deformed. I discovered that Kia has a Voluntary Emissions Service Campaign SC288 addressing this exact issue (fuel tank swelling and excessive pressure due to a faulty PCSV valve and EVAP system), but this is clearly a safety hazard, not just an emissions problem. Many other owners have reported the same issue online. I believe this defect should be escalated to a safety recall before someone gets seriously injured or worse.

NHTSA complaint #11678270 — an unverified report by a vehicle owner.

2021 KIA K5 Clarksville, TN

STRUCTURE:BODY

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.

NHTSA complaint #11674500 — an unverified report by a vehicle owner.

2023 KIA K5 Pittsburgh, PA

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

2025 KIA K5 Flagstaff, AZ Crash 1 injured

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.
