2022-2023 Kia Stinger Heads-Up Display: Failure Symptoms and Replacement Guide

Common Symptoms of a Failing HUD Assembly

Before assuming the HUD unit itself has failed, it's important to rule out simple issues. Many reported problems are not due to a faulty projector. First, check the vehicle's settings in the infotainment screen to ensure the HUD is enabled and the brightness is turned up. Also, be aware that certain types of polarized sunglasses can make the display invisible. If you wear them, try taking them off to see if the display reappears.

1. Dim or Invisible Display

One of the most common complaints is a display that is too dim to see, especially in bright daylight. While you can adjust the brightness in the settings, a display that is barely visible at maximum brightness could indicate a failing projector lamp or a problem with the power supply to the unit. In some cases, this has been linked to the use of a non-OEM or incorrect type of windshield that lacks the necessary reflective film for HUDs.

2. No Display or Intermittent Failure

If the HUD does not turn on at all, the first step is to check the vehicle's settings and the related fuse. If those are fine, the issue could be a complete failure of the HUD projector, a loose connection, or a fault in the vehicle's body control module. Some owners report the display works sometimes and not others, which can be difficult to diagnose and may point to a wiring or internal electronic fault.

3. Distorted, Blurry, or Doubled Image

A clear, sharp image depends on two things: a healthy projector and the correct windshield. If the image appears blurry, doubled (a 'ghosting' effect), or distorted, it is a strong indicator that the wrong type of windshield has been installed. A standard windshield does not have the specific layering and coating required to properly reflect the HUD's projection. If the windshield is original and the image suddenly becomes distorted, it could point to a problem with the projector's lens or internal mirrors.

4. Dead Spots or Artifacts in the Display

A user on a Stinger forum reported a persistent, perfectly round dark spot appearing in their HUD projection. This type of issue, where a piece of the display is missing or shows artifacts, almost certainly points to a failure within the projector unit itself, such as a dead pixel on the LCD screen or debris on the internal lens.

Known Issues, Recalls, and Service Bulletins

As of mid-2024, there are no specific recalls or Technical Service Bulletins (TSBs) from Kia or the NHTSA that directly address the Heads-Up Display assembly for the 2022-2023 Stinger. Most issues reported by owners are isolated incidents or related to external factors like windshield replacement or user settings.

Buying a Used 2022-2023 Stinger HUD: What to Check

Given the high cost of a new OEM unit, a recycled part is a practical option. However, this is a sensitive electronic component, and careful inspection is critical.

Verify Compatibility First

Before purchasing, confirm the part number. The primary OEM part number for the 2022-2023 Kia Stinger HUD assembly is 94310-J5410.

Physical Inspection Checklist

• Projector Lens: Inspect the glass lens on top of the unit for any deep scratches, chips, or cloudiness. Minor dust is acceptable, but physical damage to the lens will ruin the projected image.
• Electrical Connectors: Check that all connector pins are straight, clean, and free of corrosion. Bent or broken pins are a major red flag.
• Housing: Look for cracks or signs of impact on the plastic housing. This could indicate the unit was damaged during removal or in an accident, potentially harming the delicate internal mirrors and electronics.
• Cover/Lid: The unit has a movable dust cover. Ensure it is present and moves freely.

Why a Used OEM Unit is the Only Choice

For this specific part, there are no new aftermarket options available. Your choices are a very expensive new OEM part or a used OEM part. A used unit provides the exact same factory performance and compatibility as a new one, often at a fraction of the price. As long as it is inspected carefully, it is the most cost-effective solution.
