Kia initiated a recall of 100,063 K5 vehicles, models 2023-2025, on July 28, 2025, due to rear window trim pieces that may detach, creating road hazards and increasing crash risks, as reported by the National Highway Traffic Safety Administration (NHTSA). Affecting cars built between October 3, 2022, and July 24, 2024, the issue stems from faulty adhesive or mechanical fastening. Kia will notify owners starting September 26, 2025, to visit dealers for free replacement of the C-pillar trim with improved components. The recall, identified as SC346, follows four complaints reported to NHTSA in May 2025. Owners can verify their vehicle’s status using the VIN on NHTSA’s website. The fix aims to enhance safety without cost to consumers.
The recall addresses a minor but potentially dangerous defect, with Kia acting swiftly to mitigate risks. Below, we explore the issue, repair process, and broader recall context.
- Affected models: 100,063 Kia K5s, 2023-2025.
- Issue: Loose rear window trim pieces.
- Repair: Free replacement at Kia dealers.
Nature of the window trim defect
The recall targets the C-pillar trim pieces on the left and right rear windows of Kia K5 sedans, which may loosen due to inadequate adhesive or mechanical fastening. Identified in November 2023, the issue led to a service action, but escalated to a recall after four complaints reached NHTSA in May 2025. Approximately 5% of the 100,063 vehicles are estimated to have the defect, which could cause trim pieces to fall onto roads, posing risks to trailing vehicles.
Kia’s investigation confirmed that the loose trim creates a road hazard, potentially increasing crash likelihood, though no accidents have been directly linked to the issue. Vehicles manufactured after July 25, 2024, incorporate updated trim with enhanced mechanical attachments and stronger adhesive, addressing the flaw in newer production models.
- Defect cause: Weak adhesive and poor fastening.
- Risk level: 5% of vehicles affected, road hazard confirmed.
- No accidents: No crashes reported from trim detachment.
- Updated models: Post-July 2024 vehicles have fixed trim.

Kia’s recent recall history
The K5 has faced multiple recalls in 2025, including one in June for 82,281 units due to flickering parking lights, resolved via software updates. Another recall in February affected 137,256 Seltos and Soul models for faulty piston oil rings, risking engine failure. These frequent recalls, while addressed promptly, raise questions about Kia’s quality control, especially as the K5 competes in the competitive mid-size sedan market against brands like Toyota and Honda.
In 2023, Kia and Hyundai recalled 3.37 million vehicles for fire risks due to brake fluid leaks, highlighting the brands’ proactive approach but also the scale of their manufacturing challenges. The NHTSA reported 30.8 million vehicle recalls in the U.S. in 2022, underscoring the industry-wide issue of component reliability.
- Previous recalls: 82,281 K5s for parking lights, 137,256 for engines.
- Industry trend: 30.8 million vehicles recalled in 2022.
- Fire risk recall: 3.37 million Kia/Hyundai vehicles in 2023.
- Quality concerns: Ongoing scrutiny of Kia’s manufacturing.
Safety implications and industry context
Loose trim pieces, while seemingly minor, contribute to road hazards, as debris can distract drivers or cause swerving. The NHTSA estimates that 20-30% of recalled vehicles remain unrepaired, increasing safety risks. The agency’s Vehicle Safety Recalls Week, held annually in March, encourages owners to check VINs and address recalls promptly to reduce accidents, which cost the U.S. $449 million in healthcare expenses in 2024.
Kia’s recall aligns with industry efforts to address defects swiftly, but the recurrence of issues in the K5, including airbags and engine problems, suggests challenges in supply chain or assembly processes. Owners are urged to act quickly to ensure compliance with safety standards and minimize risks to themselves and others on the road.
- Unrepaired vehicles: 20-30% of recalls ignored.
- Healthcare costs: $449 million from accidents in 2024.
- K5 issues: Airbags, engines, and now trim defects.
- NHTSA campaign: Vehicle Safety Recalls Week promotes action.
