2023 Kia K5 Body & Structure Problems

•Back/Rear Windshield Trim Partial Detachment: unknown if available for inspection. •Large rear window trim piece might fall off, posing a road hazard. •Unknown if problem has been reproduced or confirmed • Unknown if component has been revised by anyone •No warning lights needed for this component

Left rear car door C-Pillar trim ripped off while driving.

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

at 2:30 PM i had noticed that my passenger rear trim, right above my trunk was loose. I made note of it. about three hours later, i was driving down the interstate and i noticed it came off and was flying through the air. Thankfully it didn’t hit another vehicle but this isn’t the first time I have had issues with the trim and a lot of other k5 owners have had issues as well.

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.

The contact owns a 2023 Kia K5. The contact stated that while the vehicle was parked, the contact observed that the trim below the rear windshield and the trunk lid trim had partially detached. The vehicle was taken to a dealer, where it was diagnosed, and it was determined that the trunk lid trim needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

I was driving with no other cars around, and i heard what sounded to be an explosion, come to find out my sunroof had exploded. I had glass fly all over the back windshield, and onto the road behind me. This could have caused an accident or damage to other vehicles if someone was around me.

Front driver side bottom bumper has unclipped randomly. I’ve spoken to a group with other 2023 Kia K5 GT-Line owners and at minimum 30 others have had the same exact clip from the bumper randomly detach. This could cause a hazard for other drivers if the bumper were to detach and possibly hang while driving at a high speed on the freeway.

The back chrome cover around the rear windshield all 3 pieces are coming loose and I had the one on my passenger side fly off while I was going down the highway and the piece almost hit the truck behind me thankfully traffic wasn’t to bad on the highway so he was able to hit his breaks and maneuver out of the way before. I currently have 2 more pieces trying to come off. After doing further research I have seen hundreds of other post from k5 owners years 23&24 all having the exact same issue of the chrome pieces coming off and or flying off while driving. In the pictures you can see the one missing piece and the other 2 you can see where the other 2 pieces are starting to loosen up. If you physically touch it they both will move and feel loose. I believe this should be a recall before one of the pieces fly off and cause a accident by hitting another car like what almost happened in my case or just flying off and hitting a person. I bought my car used but it was a single owner my car was a little over a year old I’ve personally had it for I believe 10-11 months and I keep it in the carport daily so I shouldn’t be having these issues already.
