2022 Hyundai Tucson Rear Lamp Moisture TSB 22-BD-002H
Hyundai has issued Technical Service Bulletin (TSB) 22-BD-002H for certain 2022 Hyundai Tucson (NX4a) vehicles experiencing excessive moisture in the rear center combination lamp. This bulletin provides guidance on how to inspect the lamp and determine if replacement is necessary.
Certain 2022 Hyundai Tucson (NX4a) vehicles may develop excessive moisture within the rear center combination lamp. This condition can range from normal condensation to a more severe water leak. Hyundai Technical Service Bulletin (TSB) 22-BD-002H provides a detailed procedure for inspecting these lamps and determining the appropriate repair or replacement.
This TSB is crucial for owners of affected vehicles, as it outlines the official diagnostic and repair steps for the Hyundai Tucson lamp moisture issue, ensuring proper resolution under warranty conditions.
Why This Matters
Excessive moisture inside a vehicle's lamp assembly can lead to several problems. Beyond cosmetic concerns, it can reduce light output, potentially compromise the electrical components within the lamp, and shorten the lifespan of the bulbs or LEDs. Addressing the Hyundai Tucson lamp moisture issue promptly helps maintain vehicle safety and functionality.
Symptoms
Owners of a 2022 Hyundai Tucson (NX4a) might observe visible moisture inside the rear center combination lamp. The TSB distinguishes between two conditions:
- "Normal Condensation": Characterized by "Light fogging or a faint hazy appearance. No water droplets and/or water streaks."
- "Excessive Moisture (Water Leak)": Indicated by "Visible water droplets and/or water streaks. Water may be accumulating at the bottom of the lamp assembly."
Diagnosis and Trigger Conditions
Diagnosing the Hyundai Tucson lamp moisture issue involves a visual inspection of the rear center combination lamp. Technicians will compare the observed moisture against reference photos to determine if it's normal condensation or excessive moisture. For further guidance on distinguishing between these conditions, TSB 20-BD-014H, titled "Information for Lamp Condensation," provides additional details.
If no moisture is present, no further action is required. However, if any moisture is observed, the next steps in the service procedure must be followed.
Important Warnings
Hyundai emphasizes the importance of correct diagnosis and repair. The TSB includes a critical notice:
"The drying procedure should be performed for vehicles with normal condensation. If a part is returned that does not match symptom specified, the claim will be subject to chargeback."
This means that if a lamp assembly is replaced when only normal condensation is present and the drying procedure would have sufficed, the dealer may not be reimbursed for the part. Owners should be aware that proper diagnosis is key to avoiding unnecessary part replacements.
Repair Procedure Summary
The repair process for the Hyundai Tucson lamp moisture problem begins with the inspection described above. If normal condensation is identified, the repair procedure involves following a moisture/condensation repair flowchart outlined in TSB 20-BD-014H. This typically includes a lamp assembly drying guideline.
If the inspection reveals "Excessive Moisture (Water Leak)", indicating a more severe issue, the rear center combination lamp may require replacement. In such cases, technicians are instructed to refer to the shop manual for the complete repair procedure for the rear combination lamp.
Required Parts
If the rear center combination lamp requires replacement, the following part numbers may be used, depending on the vehicle's configuration:
- 92403-CW020: Lamp Assy - Rear Combination, CTR (Bulb type)
- 92403-CW120: Lamp Assy - Rear Combination, CTR (LED type with regular rear view camera)
- 92403-CW140: Lamp Assy - Rear Combination, CTR (LED type with surround view camera)
These parts are used as causal parts for warranty claims, with Nature Code B23 and Cause Code ZZ1.
Owner Action
If you notice moisture inside the rear center combination lamp of your 2022 Hyundai Tucson, it is recommended to schedule an appointment with an authorized Hyundai dealership. They will perform the inspection outlined in TSB 22-BD-002H to determine if the condition is normal condensation or excessive moisture. If the repair is covered under warranty, claims will be submitted via the Campaign Claim Entry Screen.
If your vehicle is out of warranty, the dealership may submit a Prior Approval Request for goodwill consideration before proceeding with any repairs.
Superseded Bulletin
TSB 20-BD-014H, which is referenced for lamp condensation information, supersedes an earlier bulletin, 19-BD-003H-1. This indicates an ongoing effort by Hyundai to provide comprehensive guidance on lamp condensation issues across various models.
