Hyundai Grandeur GN7 OEM Options Review — Cost & Results

Upgrade Your Hyundai Grandeur GN7 with Factory-Spec Power Tailgate

Many owners of the latest Hyundai Grandeur GN7 find themselves missing a key convenience feature: the power tailgate. While it might seem like a premium option, retrofitting genuine OEM parts can bring this functionality to your vehicle, seamlessly integrating it as if it were factory-installed. This review explores the process, benefits, and considerations of adding this popular dealer option retrofit.

Why Add OEM Power Tailgate to Your Grandeur GN7?

The absence of a power tailgate on the Grandeur GN7 can be a noticeable inconvenience, especially for those who frequently carry groceries, luggage, or sports equipment. Manually lifting and lowering a heavy trunk lid becomes a chore, particularly when your hands are full. The allure of a factory upgrade lies in its perfect integration and reliable operation. By choosing OEM options, you ensure that the system works harmoniously with your vehicle's existing electronics and aesthetics, avoiding the potential compatibility issues or less refined operation sometimes associated with aftermarket solutions. This upgrade enhances the daily usability of your Grandeur, making loading and unloading a breeze with just the press of a button or a key fob.

The OEM Options Installation Process

Retrofitting the OEM power tailgate on a Hyundai Grandeur GN7 is a meticulous process that prioritizes maintaining the vehicle's original integrity. The installation typically involves several key steps:

1. Trunk Trim Disassembly: The interior trim panels around the trunk area are carefully removed to gain access to the necessary mounting points and wiring harnesses.
2. Component Replacement and Installation: The standard trunk latch mechanism is replaced with a motorized version. Additionally, specialized gas struts (shocks) designed for the power tailgate system are installed to provide the necessary lifting and lowering force.
3. Wiring and Module Integration: A dedicated wiring harness is routed and connected to power the new components. The system's main control module is also installed, integrating it with the vehicle's electrical system.
4. Switch Installation: A new switch for operating the power tailgate is precisely installed in a factory-like location, often on the trunk lid itself or within the cabin, ensuring convenient access for the driver and passengers.
5. System Testing and Calibration: After all components are fitted, the system is thoroughly tested. This includes checking the smooth operation of the tailgate, the responsiveness of the switches and remote, and calibrating the opening height if adjustable.

Throughout the installation, technicians ensure no permanent modifications like drilling are made to the vehicle's bodywork, preserving its original condition. The goal is to make the power tailgate function and appear as if it were a factory-fitted option from day one.

Before and After: The Convenience of a Factory Upgrade

Before the installation, the Grandeur GN7's trunk area presents a clean but manual operation. The space where a power tailgate button might typically reside is often covered. After the OEM options are installed, the transformation is significant. The most apparent change is the ability to open and close the tailgate automatically via the key fob, a button inside the car, or a button on the tailgate itself. Furthermore, the vehicle's infotainment system gains a new menu for power tailgate settings. This allows owners to customize the opening height—a particularly useful feature for garages with low ceilings—and potentially activate other smart functions. The result is a more refined and convenient ownership experience, elevating the practicality of the Grandeur GN7.

Durability and Maintenance Considerations

When genuine OEM parts are used for a factory upgrade like the power tailgate, durability is generally on par with factory-fitted components. These parts are designed and tested to withstand regular use over the lifespan of the vehicle. Maintenance is typically minimal, focusing on keeping the tailgate tracks and seals clean to ensure smooth operation. Occasional lubrication of moving parts, as recommended by the installer or manufacturer, can help maintain optimal performance. The robust nature of OEM components means that with proper care, the power tailgate should provide years of reliable service, enhancing your vehicle's functionality without adding significant maintenance burdens.

Is the OEM Options Retrofit Worth It?

For Hyundai Grandeur GN7 owners who frequently use their trunk and find manual operation cumbersome, retrofitting the OEM power tailgate is a highly worthwhile investment. The cost, while significant, is often considerably less than the original factory option price if it were available at purchase. The seamless integration, reliability, and enhanced convenience it provides directly address a common pain point. It transforms a daily task into a effortless action, adding a touch of luxury and practicality that genuinely improves the driving experience. If you value convenience and a factory-perfect finish, this dealer option retrofit is an excellent way to enhance your Grandeur GN7.
