OEM Power Tailgate Retrofit for the Hyundai Grandeur GN7
Many Hyundai Grandeur GN7 owners are looking to enhance their vehicle's convenience, and a common upgrade is the power tailgate (PTG). The question often arises: can this feature be retrofitted using genuine OEM parts, maintaining the factory look and feel? The answer is a resounding yes. For vehicles like the Grandeur GN7, if a power tailgate was an available factory option, it's possible to perform a factory option retrofit using original Hyundai/Kia components. This ensures seamless integration and the same functionality you'd get from the factory.
This review details the process, benefits, and considerations for adding an OEM power tailgate to your Grandeur GN7, based on real-world installations. We'll cover what's involved, the results you can expect, and whether this dealer option retrofit is a worthwhile investment.
The Installation Process: OEM Parts for a Factory Finish
Retrofitting an OEM power tailgate isn't just about swapping parts; it requires precise work aligned with the vehicle's original wiring diagrams. A manual trunk lacks the necessary components like a close switch. The installation process involves carefully disassembling the trunk's interior panels. Then, the essential wiring for the power tailgate system is meticulously installed, along with the new switch and buzzer, all connected according to the factory schematic.
The original manual shock absorbers are replaced with genuine power tailgate struts, fitted precisely into the factory mounting points. All wiring is routed and secured neatly. This entire process utilizes genuine Mando (a common OEM supplier for Hyundai/Kia) PTG units to ensure compatibility and performance. The goal is to make the system function exactly as if it were installed at the factory.
Installation process:
- Disassemble trunk interior panels and remove the manual trunk struts.
- Install new OEM power tailgate struts and associated components (switches, buzzer).
- Route and connect all necessary wiring according to the factory wiring diagram.
- Test all functions, including remote open/close, interior switch, and smart tailgate features.
Before and After: Enhanced Convenience with Smart Tailgate
Once the installation is complete, the Grandeur GN7 gains the full functionality of a factory-equipped power tailgate. Visually, the trunk area remains unchanged, preserving the vehicle's original aesthetic. The convenience factor, however, is significantly boosted.
You can now operate the trunk effortlessly using the smart key's trunk button. The smart tailgate feature is also activated, meaning the trunk will automatically open as you approach the vehicle with the key – a huge convenience when your hands are full. The original trunk open switch remains functional, now providing smooth, automatic operation. An interior switch, precisely installed in the factory location, allows you to close the trunk and lock the doors with a single press. Even the interior cabin switch is retained, ensuring a completely integrated and natural look and feel, as if the power tailgate was a standard feature from the assembly line.
The durability of an OEM retrofit is generally excellent, as it uses parts designed and tested for the vehicle. Maintenance typically involves keeping the struts and seals clean and ensuring no obstructions interfere with the mechanism. With proper installation and care, the OEM power tailgate should provide years of reliable service.
The cost for this type of retrofit in Korea can range from approximately ₩500,000 to ₩800,000 (roughly $370 - $600 USD, depending on exchange rates and specific components). While this is a significant investment, the added convenience and factory-like integration often make it a worthwhile upgrade for many Grandeur GN7 owners.
