2018-2023 Kia Stinger HUD Failure: Diagnosis, Replacement, and Used Buying Tips
Diagnose a failing Heads Up Display in your Stinger, understand what to look for in a used replacement, and see why this is not a simple DIY job.
- This part is only compatible with Stingers originally built with the HUD option; retrofitting is not feasible.
- Replacement is a very difficult job requiring removal of the entire dashboard, making it unsuitable for most DIYers.
- A blurry or double image is almost always caused by an incorrect non-HUD windshield, not a faulty projector.
- Before assuming the unit is broken, check that it's enabled in settings and that you are not wearing polarized sunglasses.
Symptoms of a Failing Stinger HUD
Before you suspect the HUD unit has failed, perform two simple checks. First, if you wear sunglasses, take them off. Polarized lenses can make the HUD projection completely invisible. Second, check the HUD settings in your infotainment system to ensure the display is enabled and the brightness is turned up. 🎬 Watch: How to enable or disable the Stinger HUD If the display is still not working correctly, you may have a hardware problem.
- Dim or Fading Display: The projection is very faint and difficult to see, especially during the day. This can be a symptom of a failing projector or, in some cases, an incorrect aftermarket windshield that lacks the necessary reflective properties.
- Flickering or Intermittent Display: The projection blinks, cuts in and out, or appears to shake vertically. This can point to a loose electrical connection or a failing component within the HUD projector.
- Partial or Distorted Image: Parts of the display may be missing, such as a round blind spot appearing in the projection, or the entire image may look warped or tilted.
- Complete Failure: The HUD does not turn on at all. The screen is completely blank, even after checking the system settings. This could be a failure of the unit itself or a related fuse.
- Incorrect Information or Buffering: In some cases, a failing infotainment head unit can cause the navigation portion of the HUD to get stuck on a loading or buffering screen.
Warning: A blurry or 'double' image is almost always caused by an incorrect windshield, not a faulty HUD unit. The Stinger requires a specific OEM or equivalent windshield with a special coating for the HUD projection to appear as a single, clear image.
Known Issues, TSBs, and Recalls
As of mid-2024, there are no specific recalls or Technical Service Bulletins (TSBs) from Kia or the NHTSA that directly address failures of the Heads Up Display projector unit for the 2018-2023 Kia Stinger. While the Stinger has been subject to other recalls for issues like an engine oil feed pipe and an anti-lock brake control unit, the HUD system itself has not been part of a widespread recall. Most reported issues are isolated incidents discussed by owners in online forums.
Buying a Used 2018-2023 Stinger Heads Up Display
A used OEM HUD assembly can be a cost-effective replacement, but careful inspection is critical. Given the high cost of a new unit, a quality recycled part is a smart choice.
1. Confirm Compatibility Above All Else
This is the most important step. A HUD assembly can only be installed in a Stinger that was originally equipped with the feature from the factory.
- Vehicle Requirements: A retrofit is not practical. The vehicle must have the specific dashboard with the projector cutout, the correct wiring harness, and the special HUD-compatible windshield.
- Part Numbers: Check the part number on the used unit against your original. Known OEM part numbers include 94310-J5400 (typically for 2018-2021 models) and 94310-J5410 (for 2022-2023 models). While they may be interchangeable, it's best to match the part number exactly.
2. Physical Inspection of the Used Unit
Before purchasing, inspect the used assembly carefully:
- Projector Lens: Look at the glass lens on the top of the unit. It should be free of deep scratches, chips, or cracks.
- Electrical Connector: Inspect the pins in the electrical connector. They should be straight, clean, and free of any corrosion or damage.
- Housing: Check the plastic housing for any signs of cracking, heat damage, or moisture intrusion. Water damage can destroy the internal electronics.
- Ask the Seller: Inquire about the donor vehicle. Ask for confirmation that the HUD was fully tested and working before it was removed. Knowing the mileage of the donor car can also be helpful, as the projector's light source has a finite lifespan.
Installation and Calibration
Warning: This is not a beginner-friendly repair. Replacing the HUD assembly requires the complete removal of the upper dashboard, a time-consuming and complex process.
Installation Difficulty: 5 out of 5
The HUD projector is located deep under the dashboard panel near the windshield. The general procedure involves:
- Disconnecting the vehicle's battery.
- Removing A-pillar trims, the instrument cluster, and center console components.
- Unbolting and carefully removing the entire upper dashboard assembly 🎬 See these tips for removing Kia Stinger dash trim to gain access to the HUD unit.
- Unplugging and unbolting the old unit, installing the new one, and reassembling everything in reverse order.
Calibration:
After installation, basic adjustments for height, rotation, and brightness can be made through the vehicle's settings menu in the infotainment screen. 🎬 Watch: How to adjust the Stinger HUD height and rotation No special programming is typically required for the HUD unit itself. However, if the windshield was also replaced, the forward-facing camera and other safety sensors attached to it will require professional calibration to ensure features like lane-keep assist and forward collision warning function correctly.
Cost Comparison
Prices for the HUD assembly can vary significantly. This is a complex electronic part that is expensive to purchase new.
| Part Source | Estimated Cost |
|---|---|
| New OEM | $1,800 - $2,800 |
| New Aftermarket | Not Available |
| Used OEM | $300 - $700 |
| Shop Labor | $600 - $1,000+ |
Frequently Asked Questions (FAQ)
Can I add a factory HUD to my Stinger if it didn't come with one?
This is not considered a practical or cost-effective modification. It would require replacing the dashboard, windshield, and entire wiring harness, in addition to sourcing the HUD unit itself.
My HUD is blurry or I see a double image. Is the projector broken?
Almost certainly not. This symptom is a classic sign that the incorrect windshield is installed. Your vehicle must have a HUD-specific windshield with a special reflective coating to focus the projection into a single, sharp image.
Why can't I see my HUD display on sunny days?
First, check your infotainment settings to ensure the brightness is set to maximum. If it's still invisible, the issue is likely that you are wearing polarized sunglasses, which can completely block out the light from the HUD.
Does a replacement HUD need to be programmed by the dealer?
No, the HUD unit itself typically does not require special programming. However, you will need to use the car's settings menu to calibrate its position (height/rotation) on the windshield. If other work was done, like a windshield replacement, other vehicle systems may need calibration.
