Hyundai Motor Company and Kia Corporation have patented a pickup-truck tailgate that can open in two directions using one drive motor. A conventional mode swings the complete gate down around a primary hinge; a second mode moves only a gate section sideways around another hinge to provide side access to the bed. The US patent documents explain the gears, clutch, latches and safety logic, but they do not identify a production truck, launch date, price or retrofit kit. The design is therefore a documented engineering concept—not a confirmed feature for the Hyundai Santa Cruz or any other named model.
What does Hyundai’s dual-action power tailgate patent do?
The invention combines a normal drop-down tailgate with a side-opening section. Its gate portion has first and second hinges. The first hinge moves the main gate around the vehicle’s usual tailgate axis, while the second hinge lets a portion of the gate swing sideways for access from beside the truck.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
That arrangement addresses the limitation described in the patent background: “Pickup trucks generally have a tailgate which can be opened and closed along a singular axis.” A driver could retain a full-width loading opening for bulky cargo, then use the side-opening mode when standing beside the bed or reaching into a corner.
What the two opening modes provide
| Mode | Movement | Practical access | Status in the documents |
|---|---|---|---|
| Standard open | The complete gate rotates around the first hinge | Conventional rear loading and a lowered tailgate surface | Described in the patent control sequence |
| Side open | A gate portion rotates around the second hinge | Access from the side of the bed without lowering the entire gate | Described in the patent control sequence |
How does the single-motor mechanism select an opening direction?
The patent uses one drive motor and a clutch to choose between two hinge gears. This avoids dedicating a separate powered actuator to each opening axis, although it adds mechanical and electronic coordination.

- The drive motor turns a common drive gear.
- A clutch motor shifts the clutch so that drive gear engages either the first hinge gear or the second hinge gear.
- In some versions, slotted rails move the drive motor between the two engagement positions, helping align the drive gear with the selected hinge gear.
- The engaged hinge gear then rotates the relevant gate section around its hinge.
The described hardware can also include a pivot-cup hinge, a spindle drive, first and second latches, a computing controller and position-sensing components. The patent describes these as parts of possible implementations rather than a published production specification.
What safety checks happen before the tailgate moves?
The control logic is conditional: a switch command alone is not enough to start the motor. The controller first identifies which opening request was made, verifies vehicle and latch conditions, then selects the corresponding mechanical path.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors- The driver presses either the standard-open switch or the side-open switch.
- The controller checks that the vehicle is stopped.
- It verifies that the tailgate is fully latched before commanding an opening cycle.
- The controller releases the latch associated with the requested movement.
- The clutch motor shifts the drive gear into engagement with the selected hinge gear.
- The drive motor runs to move the complete gate or the side-opening portion.
The records do not specify obstacle-detection performance, motor speed, load limits, weather resistance or a durability rating. Those details would be necessary before judging how the system behaves with an obstruction, an uneven load or a partially closed gate.

Is this a production feature for the Hyundai Santa Cruz?
No production application has been identified. The patent uses generic pickup-truck language and does not name the Santa Cruz, another Hyundai truck, a Kia model or a future vehicle. It also provides no showroom launch schedule, option code, compatible part number or consumer price.
A patent grant establishes intellectual-property rights, not a commitment to manufacture. Automakers routinely patent mechanisms that may be adapted, delayed or never commercialized. Hyundai or Kia would need a separate product announcement, vehicle specification or parts listing to confirm that this tailgate is headed for a particular truck.
What is the US patent’s legal status?
The US application was filed on February 20, 2024, with that date also listed as the priority and filing date. Publication followed on August 21, 2025, as US20250263963A1. A later record reports US Patent 12,716,285 issued on August 25, 2026. Hyundai Motor Company and Kia Corporation are listed as assignees, and Eoin Minaker and Kihyun Cho as inventors.

The issued patent strengthens the companies’ rights over the claimed invention, but it does not establish that a production tailgate exists or that the claims will appear unchanged in a vehicle.
How is this different from a normal drop-down or side-opening tailgate?
A normal drop-down tailgate has one principal hinge axis and usually one latch arrangement. A side-opening design pivots the gate laterally, which can improve side access but does not provide the same lowered loading surface. Hyundai’s concept combines both movements in one gate assembly.
| Comparison point | Conventional drop-down gate | Hyundai/Kia patented concept |
|---|---|---|
| Opening direction | Rearward/downward | Rearward/downward or sideways |
| Drive arrangement | Varies; the patent does not establish a powered baseline | One drive motor with a clutch selecting two hinge gears |
| Mechanical complexity | Single primary hinge and latch path | Two hinges, selectable gearing, multiple latches and clutch movement |
| Interlocks described | Not established by these records | Stopped-vehicle and fully-latched checks before release and drive |
| Bed access | Best for rear loading with the gate lowered | Rear loading plus side access to the bed |
| Confirmed vehicle fitment | Depends on the truck | None announced |
| Commercial status | Established hardware category | Patent; no production or retail application identified |
Can you buy this tailgate or an aftermarket kit?
There is no identifiable retail product for the patented assembly in the available records. They do not list a kit, supplier, price, installation procedure or model compatibility. A listing that claims to be this exact Hyundai/Kia system would need verifiable vehicle fitment and manufacturer documentation before it could be treated as genuine.

Does the patent mean a new Hyundai pickup is launching soon?
No. Patent publication and grant do not provide a launch timetable. The documents do not name a truck or state that production tooling or vehicle validation has begun.
Could the side-opening section work if the truck is parked on a slope?
The described controller checks that the vehicle is stopped, but the records do not state slope limits, level sensors or behavior on an incline. Those operating conditions would require production documentation.
