2021-2024 Hyundai Wiper Blade Protective Cover TSB

Hyundai has released Technical Service Bulletin (TSB) 24-BD-001H to provide essential instructions for the proper removal of the windshield wiper blade protective cover. This bulletin applies to all new Hyundai wiper blades across various models from 2021 to 2024. Following the correct procedure is crucial to prevent potential issues with your vehicle's visibility system.

Why This Matters

Improper removal of the Hyundai wiper protective cover can lead to significant problems. If the protective cover is not removed correctly, the rubber insert and rail spring on the inner side of the wiper blade can become partially separated. This separation can result in poor wiping performance, leaving streaks or unwiped areas on your windshield. More critically, it could lead to possible scratching of the windshield glass, which is an expensive repair and a safety hazard.

What's Being Addressed

This TSB specifically addresses the protective cover found on new windshield wiper blades. This cover is designed to protect the wiper blade during shipping and installation. The core issue arises when this cover is removed incorrectly, causing internal components like the rubber insert or rail spring to shift or detach. Ensuring the integrity of these components is vital for effective and safe windshield clearing.

Symptoms of Incorrect Removal

If the windshield wiper blade protective cover is not removed as intended, owners may notice immediate symptoms. The most common signs include poor wiping performance, where the wipers fail to clear the windshield effectively. This can manifest as streaking, chattering, or missed spots. In more severe cases, the separated components could cause direct contact between the wiper arm's metal parts and the glass, leading to scratching of the windshield glass.

How to Properly Remove the Hyundai Wiper Protective Cover (TSB 24-BD-001H)

To ensure proper function and prevent damage, follow these steps for removing the Hyundai wiper protective cover on new wiper blades, as detailed in TSB 24-BD-001H:

1. Lift the Wiper Blade: Gently lift the entire wiper blade assembly away from the windshield until it locks into its upright position.
2. Remove the Cover: With the blade lifted, carefully remove the protective cover. The TSB specifies removing it in the direction of the arrows typically shown on the cover itself, usually by sliding it off the end of the blade.
3. Inspect the Blade: After removing the cover, visually inspect the wiper blade. Confirm that the rubber insert and the internal rail spring are securely in place and have not separated or shifted.

Important Warnings

Hyundai explicitly warns against a common mistake during this process. The bulletin states: "Do not pull down on the protective cover." Pulling down on the cover can force the rubber insert or rail spring out of position, causing the very damage this TSB aims to prevent. Always slide the cover off as directed.

Owner Action

If you are installing new wiper blades on your 2021-2024 Hyundai vehicle, it is important to follow the correct removal procedure for the Hyundai wiper protective cover as outlined in TSB 24-BD-001H. This simple step can prevent future issues with wiping performance and potential damage to your windshield. If you have any concerns or experience poor wiping performance after a recent wiper blade installation, you may wish to inspect the blades or consult with a Hyundai service technician.
