2018-2023 Kia Stinger Exterior Trim: Common Problems and Replacement Guide

Known Issues with 2018-2023 Kia Stinger Exterior Trim

While the Kia Stinger is a popular sport sedan, several common issues have been reported by owners regarding its exterior trim components. These problems are primarily cosmetic but can be frustrating for owners who want to maintain the vehicle's sharp appearance.

Fading and Tarnishing Window Trim

The most widely reported exterior trim issue is the premature fading, clouding, and tarnishing of the dark or satin chrome window moldings. Owners report that the finish develops a milky or oxidized appearance that cannot be cleaned or polished away easily. This issue appears to be caused by a subpar material finish that reacts poorly to environmental exposure and car wash chemicals. While some dealers have replaced this trim under warranty, the replacement parts can suffer from the same problem over time. As a result, many owners opt to cover the affected trim with a vinyl wrap (a process called 'chrome delete') for a more permanent solution.

Loose or Detached Fender Garnishes (Side Vents)

The decorative fender garnishes, also known as side vents, can become loose. These are typically held in by plastic clips that can become brittle or break during removal or from minor impacts. While not a widespread failure, it's a point of concern when replacing or inspecting them. Aftermarket versions, including popular carbon fiber options, are widely available.

Paint Flaking on Sunset Yellow Models

An early issue affected some 2018-2019 Stinger models painted in Sunset Yellow. The paint was found to be prone to excessive cracking and flaking due to an issue with the oil in the paint mixture affecting durability. This was subject to a recall, so any used model with this color should have its history checked.

Recalls and Technical Service Bulletins (TSBs)

NHTSA Recall 18V-754: Wiring Harness Damage

This early recall affects 16,011 units of the 2018 Kia Stinger. The engine wiring harness could potentially make contact with a burr on the left front fender panel. This contact could damage the wire insulation, leading to a short circuit and increasing the risk of a fire. The remedy involves inspecting the harness, repairing it if necessary, and installing a protective cover. When purchasing a used 2018 model, it is crucial to verify that this recall has been completed.

NHTSA Recall 24V-169: Turbocharger Oil Feed Pipe

Affecting 2018-2023 Stingers with the 3.3L twin-turbo V6 engine, this recall addresses an oil feed pipe and hose assembly for the left-hand turbocharger that can deteriorate from engine heat. This can cause an oil leak, which poses a fire risk if it drips onto hot exhaust components. Symptoms include a burning oil smell, smoke from the engine bay, or an oil pressure warning light. The fix is to replace the assembly with an improved part.

Service Action SA483: Front Door Trim Grip Handle

This is a service action, not a full recall, for some 2022 Stinger models. The interior front door grip handle may detach from the door trim. Dealers will repair the handle by replacing the mounting bracket screws with longer, more secure ones.

Buying a Used Exterior Trim Panel

When buying a used OEM exterior trim piece like a fender garnish or window molding for your Stinger, careful inspection is key to getting a quality part. Used OEM is often superior to cheap aftermarket alternatives in terms of fit and finish.

What to Inspect on a Used Part

• Mounting Tabs and Clips: This is the most critical area. Inspect all mounting tabs and clip locations for cracks, stress marks, or complete breakage. The fender garnishes, in particular, rely entirely on these clips to sit flush. A part with broken tabs will not install securely.
• Finish and Condition: For window trim, check for the common signs of tarnishing or cloudiness. For painted parts like fender garnishes, look for deep scratches, scuffs, or peeling clear coat.
• Previous Repairs: Look for signs of glue or epoxy on the backside, which might indicate a previous attempt to repair a broken tab. Avoid these parts.
• Color Match: For pre-painted parts, ensure the color matches your vehicle. Be aware that sun exposure can slightly alter a car's paint over time, so a used part from a different vehicle may not be a perfect match even with the correct paint code.

How to Verify Paint Code and Color Match

The paint code for your Kia Stinger is located on a sticker in the driver’s side door jamb. The code is typically a two or three-character combination of letters and numbers, usually found next to the word "PAINT". 🎬 Watch: How to find the paint code on your Kia. When ordering a painted part, providing your vehicle's VIN is the most reliable way for a seller to ensure an exact color match.

Cost Comparison for Fender Garnish Replacement

Costs can vary based on location and whether the part is pre-painted. The fender garnish is a relatively simple part to replace.
