Hyundai Grandeur GN7 Ghost Door Review — Enhanced Luxury

What is Ghost Door (Auto-Closing)? The Mark of a Luxury Sedan

The auto-closing function, often referred to as 'Ghost Door' or 'e-Closing', automatically pulls in slightly ajar car doors, a signature feature found in luxury vehicles like Genesis. Today's Car is showcasing the step-by-step luxury tuning process for the Hyundai Grandeur GN7. While previously exclusive to vehicles with factory-installed systems, the availability of universal kits now allows this premium feature to be retrofitted to a wider range of domestic vehicles, including the Grandeur GN7.

Why Installation Quality Matters for Auto-Closing

Even with universal kits, the actual quality of the installation can vary significantly depending on the expertise of the workshop. This is because the kit needs to be precisely adapted to the specific door structure of the Hyundai Grandeur GN7. Using the same product, a lack of precision can lead to jerky operation or unwanted noise. Therefore, it is highly recommended to have your auto-closing system installed by a skilled and experienced workshop. Today's Car Seocho Branch is renowned for its customized installations tailored to each vehicle model.

Installation Process: Hyundai Grandeur GN7 Auto-Closing

1. Initial Vehicle Inspection: Before work begins, the condition of the car doors is meticulously checked. This includes door gaps, latch alignment, and electrical wiring routes. Given the precise door structure of the Grandeur GN7, this step is crucial, as even minor deviations can affect the final operation.
2. Door Trim Removal: The core of the installation involves securely fixing the motor while preserving original parts as much as possible. The door trim is carefully removed to expose the internal structure. The Grandeur GN7's door interior is complex, filled with wiring and sound-deadening material, making careful handling essential to avoid damaging other functions.
3. Latch and Motor Installation: Once the door trim is off, the original latch mechanism is exposed. This is where the auto-closing motor will be installed. The motor-equipped latch from the universal kit is precisely aligned and secured within the door. Maintaining consistent spacing and proper screw torque between the existing latch and the new component is vital.
4. Wiring and Control Module Setup: After securing the motor, power wiring commences. The internal space of the Grandeur GN7's door is utilized efficiently to manage the wiring neatly. The motor is typically installed on the inner side of the trim, ensuring it remains hidden from view. Wiring is routed separately from the car body to prevent interference or short circuits. The control module, which governs the motor's operation, is installed similarly. It receives a signal when the door engages with the car's striker (the metal part the door latches onto), activating the motor.
5. Testing and Finalization: The system is tested to ensure smooth and reliable operation. The auto-closing function should engage promptly and quietly, pulling the door shut completely.

How Auto-Closing Works and Safety Features

The principle behind auto-closing is elegantly simple yet requires sophisticated engineering. The moment the car door engages with the striker, a sensor detects this and signals the internal drive motor to activate, automatically pulling the slightly open door shut. This process is remarkably fast, typically taking 0.5 to 1 second, allowing the driver to simply nudge the door closed, and it will then fully secure itself. A critical aspect is the safety feature: if the system detects an obstruction, such as a finger or object, during the closing process, it immediately stops and reopens the door, preventing injury or damage.
