2016-2020 Kia Sorento Liftgate Garnish: Cracks, Rattles, and Replacement Guide

Symptoms of a Failing Liftgate Garnish

Since this is a cosmetic and structural part, failure symptoms are almost always visible or audible. There are no associated dashboard warning lights or diagnostic trouble codes for the garnish itself.

• Visible Cracks: The most common failure is the development of cracks in the plastic. These can be small hairline fractures, often starting near mounting points or the emblem, or large, obvious breaks. These are typically caused by long-term exposure to UV sunlight and extreme temperature changes, which make the plastic brittle.
• Peeling or Faded Finish: The painted or chrome surface of the garnish can degrade over time. You might notice the clear coat peeling, the color fading, or the chrome finish bubbling or flaking off.
• Rattling or Squeaking Noises: If the garnish's mounting clips or bolts become loose or broken, the entire panel can vibrate against the liftgate, causing rattling or squeaking sounds, especially when driving on uneven roads or closing the liftgate.
• Loose Fitment: You may be able to physically wiggle the garnish, indicating that it is no longer securely attached to the liftgate. This is a sign of broken mounting tabs on the back of the panel.

Known Issues, Recalls, and Service Bulletins

While there are no recalls specifically for the liftgate garnish panel on the 2016-2020 Kia Sorento, several related issues are important for owners to be aware of, as they involve components in the same area.

• Service Action SA234: This service action applies to some 2016 Sorento models with a manual tailgate. A faulty component within the latch could prevent the liftgate from opening from the outside. Dealers were instructed to install updated latch components to resolve the issue.
• Rearview Camera Clip Recall (NHTSA 23V610000): On some 2022-2023 Sorento models, the mounting clips for the rearview camera can break, causing the camera image to fail. While this recall is for a newer generation, it highlights a potential failure point for a component housed within the garnish. When inspecting a used garnish, pay close attention to the camera mounting points.
• Trunk Latch Cracking Recalls: Kia has issued recalls for other models like the Optima and Rio because a plastic pawl inside the trunk latch assembly can crack in high temperatures, preventing the trunk from being opened from the inside. This shows a history of plastic components in this area being susceptible to thermal stress.

Buying a Used 2016-2020 Sorento Liftgate Garnish

A used OEM (Original Equipment Manufacturer) garnish is often an excellent value compared to a new part from the dealer, but a thorough inspection is key. A quality used part will fit perfectly and match your vehicle's finish, something that can be a gamble with cheaper aftermarket alternatives.

What to Inspect Before You Buy:

1. Check for Hairline Cracks: Carefully examine the entire surface, especially around the Kia emblem, handle cutout, and any corners. Flex the part slightly (if possible) to reveal hidden stress cracks.
2. Inspect All Mounting Tabs: This is the most critical check. Flip the garnish over and inspect every single mounting tab and clip post. These small plastic posts are what secure the garnish to the liftgate. If even a few are broken, the garnish may not sit flush and could rattle or eventually fall off.
3. Verify the Finish and Color: The Sorento was available with different trim packages, which could mean different finishes for the garnish (e.g., gloss black, satin silver, chrome). Ensure the part you're buying matches your vehicle's trim level.
4. Check Integrated Components: Many used garnishes are sold complete with the rearview camera and liftgate release handle. Inspect the camera lens for scratches or fogging and check the rubber on the release button for wear or cracks.
5. Confirm Part Number: The primary part number is 81730C6000WK. However, there may be slight variations depending on whether your vehicle has a factory rearview camera. Always verify fitment with the seller.

Cost to Replace a 2016-2020 Sorento Liftgate Garnish

The cost can vary depending on where you source the part and whether you perform the labor yourself. The replacement is a manageable DIY job for those comfortable with basic tools.

Replacement Overview

Replacing the liftgate garnish is straightforward but requires care to avoid damaging the plastic trim panels. The difficulty is approximately a 2 out of 5.

1. Open the Liftgate: Secure the liftgate fully open.
2. Remove Interior Trim Panels: Start by removing the interior plastic trim from the liftgate. This usually involves removing an upper center piece, two side pieces, and the large main panel. Look for screws inside the pull handle and under small plastic caps. The rest of the panels are held by clips that release when you pull firmly but gently.
3. Disconnect Electrical Connectors: Once the main interior panel is off, you will see the back of the exterior garnish. Disconnect the wiring harnesses for the rearview camera, license plate lights, and the liftgate release handle.
4. Remove the Garnish: The garnish is held on by several nuts (likely 10mm) and retaining clips. Remove all the nuts, then carefully push on the mounting studs from the inside while gently prying from the outside to release the clips.
5. Install the New Garnish: Clean the mounting surface on the liftgate. Position the new garnish, ensuring all clips and studs line up with the holes, and press it firmly into place. Reinstall the nuts from the inside, but do not overtighten, as you can strip the plastic studs. Reconnect all electrical components and test them before reinstalling the interior trim panels.
6. Reassemble: Reinstall the interior trim panels in the reverse order of removal. Make sure all clips are aligned before pressing them into place.
