Problem overview

Some Hyundai Sonata owners report experiencing issues with the shark fin antenna cover detaching while driving, leading to safety concerns. Although driving without the cover may not pose an immediate danger, it can decrease signal strength and increase static noise, affecting the car's functionality. Additionally, some owners have noted that weakened mounting bosses on certain Sonata models can cause the antenna cover to loosen with external force. There have been instances of the cover blowing off while driving, which can create hazards if it strikes another vehicle or causes drivers to swerve. Furthermore, Hyundai has recalled over 400,000 vehicles due to a faulty antenna assembly process that may allow water to enter and damage other components. It is crucial for Sonata owners to address these issues promptly to ensure their vehicles' safety and proper operation.
