The Genesis GV90—the upcoming flagship electric SUV from Hyundai’s luxury brand—has once again stirred curiosity, and this time it’s not just about its ultra-luxurious coach doors. A recent sighting of the GV90 prototype in Germany has revealed a surprising detail: a warning message written in both Korean and English on the inside of the rear door, asking observers “Please do not open the door.” This curious advisory raises a compelling question: Is Genesis still grappling with issues related to the complex coach door system?
Warning Sign on Coach Doors: A Red Flag?
Spotted by the eagle-eyed team at SH Proshots, the prototype was seen with minimal camouflage, providing the clearest look yet at the GV90’s signature coach doors. However, the handwritten-style message on the rear door immediately caught attention—especially given the model’s past delays allegedly linked to door mechanism concerns.
Coach doors—rear-hinged doors famously used by Rolls-Royce—require sophisticated engineering due to their weight, hinge complexity, and stringent safety requirements. Genesis’ implementation of this feature represents a bold move, positioning the GV90 alongside the world’s most exclusive luxury vehicles. But could the brand still be fine-tuning a system that’s proven notoriously difficult to perfect?
The sign warning not to open the door could indicate ongoing reliability or safety concerns during real-world testing. It’s not unusual for prototype vehicles to feature such notices, but their presence—especially in both Korean and English—suggests a consistent, possibly unresolved issue that testers want to avoid exacerbating.

A History of Coach Door Challenges
This isn’t the first time Genesis has faced hurdles with the GV90’s development. Industry insiders previously noted that the unique rear door design contributed to delays in early real-world testing phases, likely due to engineering challenges in achieving both durability and safety compliance with the unconventional layout.
As one of the most mechanically intricate components of the vehicle, the coach door system must meet modern crash safety standards, integrate seamlessly with EV structural design, and still provide the wow factor that buyers in the ultra-luxury segment demand.
The GV90: Still a Game-Changer in the Making
Despite these possible hiccups, the GV90 remains one of the most anticipated electric luxury SUVs on the horizon. Genesis has made it clear that this model will represent the pinnacle of its design, performance, and innovation:
- Coach Doors: A dramatic and luxurious feature previously reserved for elite marques like Rolls-Royce.
- Dedicated eM EV Platform: Offering a spacious interior and flat-floor architecture, built for long-range efficiency.
- Premium Cabin: Expect the most lavish Genesis interior yet, with high-end materials, advanced wellness tech, and cutting-edge infotainment.
- Flagship Performance: A dual-motor AWD setup and a target range exceeding 700 km (434 miles) are expected.
Are the Coach Doors Still a Risk?
While the GV90’s ambition is clear, the recent sighting raises valid questions:
- Are Genesis engineers still fine-tuning the coach door mechanics?
- Could lingering issues impact production timelines?
- Will customers trust a door system that’s already raised engineering red flags?
We’ll likely get answers as Genesis moves closer to the GV90’s official debut. But for now, this “Do Not Open” sign is more than just a curious footnote—it’s a subtle signal that even the most luxurious innovations come with their own set of challenges.
