Genesis G90 Ghost Door Retrofit Review - Cost & Results

Enhancing the Genesis G90 with Ghost Doors

The Genesis G90 stands as a flagship sedan, yet certain desirable features, like the ghost door function, aren't always standard. For owners seeking to elevate their driving experience, adding these factory options can significantly enhance convenience and luxury. This review details the process of retrofitting genuine OEM ghost doors onto a Genesis G90 RS4 model, focusing on the installation, cost, and overall value. The original context for this work comes from a detailed guide by 'Today's Car' in Seoul, South Korea, highlighting a specific installation on a G90 RS4.

Why Consider Ghost Doors for Your G90?

While the G90 is already a premium vehicle, the ghost door feature offers a subtle yet impactful improvement. This system automatically and gently closes the doors, providing a quiet and refined experience, especially beneficial in tight parking spaces or when passengers need assistance entering or exiting. It adds a touch of sophistication that aligns with the G90's flagship status. The convenience of a door that closes itself with just a slight push is a feature many owners find indispensable once experienced, particularly for those frequently using the rear seats.

OEM Ghost Door Installation Process

Retrofitting ghost doors involves more than just adding a motor; it requires integrating genuine OEM components and ensuring seamless system integration. The process, as performed by specialists like 'Today's Car' in Seoul, involves several key steps:

1. Component Integration: Vehicles without the factory ghost door option are missing the necessary latch mechanisms, suction motors, wiring harnesses, and control units (ECU). The installation requires fitting these specific OEM parts into the doors.
2. Wiring and ECU Connection: A crucial step involves precisely connecting the new components to the vehicle's existing electrical system. This includes running new wiring and ensuring the new modules communicate correctly with the car's main ECU.
3. Software Coding: Once the hardware is installed, diagnostic tools are used to code the vehicle's ECU. This activates the ghost door functionality and ensures it's recognized by the car's onboard systems, much like a factory-installed option.
4. Testing and Verification: After coding, thorough testing is performed to confirm the ghost doors operate smoothly and reliably, ensuring a perfect fit and function without any warning lights or errors.

Using genuine OEM parts ensures that the fit and finish are indistinguishable from factory-installed options, avoiding the potential issues associated with aftermarket alternatives. The durability of this system, when installed correctly with OEM components, is expected to be on par with other factory features, requiring minimal maintenance beyond ensuring the door seals remain clean.

Cost, Durability, and Value Proposition

The estimated cost for this OEM ghost door retrofit in South Korea is approximately ₩115,000 to ₩150,000 (Korean Won), which translates to roughly $85-$110 USD at current exchange rates. This price reflects the cost of genuine parts and specialized labor. In terms of durability, OEM components are designed for the vehicle's lifespan, meaning the ghost door system should last for many years with proper care. Maintenance is generally minimal, focusing on keeping door mechanisms and seals clean. When considering whether this factory upgrade is worth it, potential buyers should weigh the added convenience and luxury against the cost. For those who frequently transport passengers or appreciate the refined operation of their G90, the investment in OEM ghost doors can significantly enhance the ownership experience, making it a worthwhile addition for a truly complete flagship sedan.
