2015-2017 Kia K900 B-Pillar Trim: Addressing Rattles, Scuffs, and Replacement
This guide covers the common cosmetic issues, replacement procedure, and buying advice for the interior B-pillar trim panels on the 2015-2017 Kia K900.
- The OEM part number 664003T000 is for the hood, not the B-pillar trim; always verify the correct trim part number with your vehicle's VIN.
- Most failures are cosmetic (scratches) or cause rattles due to broken mounting clips on the back of the panel.
- Replacement is a simple DIY job requiring only a plastic trim tool, but care must be taken around the seatbelt and curtain airbag.
- While this part has no recalls, the 2015-2017 K900 has a critical fire-risk recall for the ABS module that all owners must address.
Part Number Verification
Important: The OEM part number 664003T000 is frequently associated with this vehicle range but is for the hood panel assembly, not the B-pillar trim. Due to variations in interior color (e.g., beige, black) and material (cloth or potential suede options), you must verify the exact part number for your specific vehicle using its Vehicle Identification Number (VIN) at a dealership or reputable online parts store.
Symptoms of a Failing B-Pillar Trim Panel
Since the B-pillar trim is not a mechanical part, "failure" relates to cosmetic, fitment, or noise issues rather than functional breakdown. Common symptoms are straightforward to spot.
1. Cosmetic Damage
The most common issue is surface wear and tear. This includes scratches, scuffs, and gouges from the seatbelt buckle repeatedly hitting the panel, or from loading and unloading passengers and cargo. On the luxury-oriented K900, which may have soft-touch or fabric-wrapped panels, you might also see peeling material or discoloration from sun exposure over time.
2. Rattling or Loose Fit
A rattling, buzzing, or vibrating noise coming from the area between the front and rear doors is a strong indicator of a problem with the B-pillar trim. These panels are held in place by a series of plastic clips. Over time, or especially after being removed for other repairs, these clips can become brittle and break. When the clips fail, the panel will no longer sit flush and will vibrate against the vehicle's body, creating noise.
3. Problems with Seatbelt Operation
The trim panel has a slot for the seatbelt and houses the height adjuster. If the panel is severely damaged or dislodged, it could potentially interfere with the seatbelt's ability to retract or adjust smoothly. This is a safety concern that should be addressed immediately.
Vehicle-Specific Known Issues, TSBs, and Recalls
B-Pillar Trim Panel
There are no known recalls, Technical Service Bulletins (TSBs), or widespread owner complaints specifically concerning the B-pillar trim panels on the 2015-2017 Kia K900. Issues are typically isolated incidents of wear and tear.
Important Vehicle-Wide Safety Recalls
While the trim panel itself is not subject to recalls, all owners of a 2015-2017 Kia K900 should be aware of a critical safety recall.
Fire Risk Recall: Kia issued a recall for a defect in the Hydraulic Electronic Control Unit (HECU), which is part of the anti-lock brake system. This defect can cause an electrical short, potentially leading to an engine compartment fire, even when the vehicle is parked and turned off. Owners are advised to park their vehicles outside and away from structures until the free recall repair is completed by a Kia dealer. You can check if your vehicle is affected by entering your VIN on the NHTSA website.
Buying a Used Body B-Pillar Trim Panel
Given the high cost of new OEM parts, a used or recycled trim panel is an excellent value. Since this is a cosmetic part, you can find a part in like-new condition for a fraction of the price. Here’s what to check:
- Inspect All Mounting Clips: This is the most critical inspection point. Turn the panel over and ensure all the plastic clips and mounting tabs are present and intact. Even one broken clip can cause a rattle. If a clip is missing, the panel is of little use unless you can source replacement clips separately.
- Check for Cracks and Stress Marks: Carefully inspect the front and back of the panel, especially around the seatbelt slot and mounting points, for any cracks or white stress marks in the plastic. These indicate the part was removed carelessly or has been damaged.
- Verify Color and Finish: The K900 was offered with different interior color schemes. Ensure the color of the used panel is an exact match for your interior. Take a photo of your existing trim in good lighting to compare.
- Examine the Surface: Look for deep scratches, gouges, or signs of peeling on the surface. Minor scuffs may be acceptable and can often be cleaned up, but deep damage cannot be repaired.
Replacement Information
Replacing the B-pillar trim panel is a straightforward job suitable for a DIYer with basic tools.
Pro Tip: A set of plastic trim removal tools is highly recommended. Using metal tools like a screwdriver will almost certainly scratch or gouge the panel and surrounding trim.
- Adjust the Seatbelt: Move the seatbelt height adjuster to its lowest position.
- Remove Surrounding Trim (If Necessary): In some cases, you may need to gently pull back the door weatherstripping to get access to the edge of the panel.
- Pry the Panel Off: Start at the top or bottom edge and use a plastic trim removal tool to gently pry the panel away from the B-pillar. You will hear the clips pop as they release. A Korean-language video for a newer model shows the panel is held by four main clips. Work your way around the panel until it is free.
- Maneuver Around the Seatbelt: Once the panel is loose, you will need to carefully guide it off and around the seatbelt assembly. Do not force it.
- Install the New Panel: Guide the new panel over the seatbelt. Align the clips with the corresponding holes in the B-pillar. Once aligned, give the panel a firm tap with the palm of your hand over each clip location to snap it into place.
Warning: Be careful not to trap or damage the side curtain airbag, which is located in this area, when reinstalling the trim.

Frequently Asked Questions
Is the B-pillar trim the same for the driver and passenger side?
No, they are not interchangeable. The panels are mirror images of each other to accommodate the seatbelt mechanism for the left and right sides. You must purchase the correct panel for the side you are replacing.
My trim panel is rattling. Do I need to replace the whole thing?
Not necessarily. The rattle is almost always caused by broken or loose mounting clips. You may be able to remove the panel, replace only the broken clips (if available separately), and reinstall it securely. If the clip receptacles on the panel itself are broken, then the entire panel will need to be replaced.
Can I just glue a loose trim panel back on?
This is not recommended. Adhesives can make future removal impossible without destroying the panel, can interfere with the function of the curtain airbag, and may not hold up to temperature changes inside the car, leading to failure.
Is the K900 fire risk recall related to this interior trim part?
No. The major fire risk recall for the 2015-2017 Kia K900 is related to the anti-lock brake system's HECU module in the engine bay and is completely unrelated to the interior trim panels.
