The Falcon Wing Doors (FWD) on the Model X are its most iconic and complex feature. As of 2026, many early mechanical issues have been addressed, but sensors and alignment still present regular "gremlins."
Here are 5 labels for Model X Falcon Wing Door issues, updated for 2026:
Phantom Obstacle Detection,
Cause: Ultrasonic sensors (USS) are glued inside the door panel. Extreme heat (parking in direct sun) can melt the adhesive, causing the sensor to tilt and "see" the internal metal of the door as an obstacle.
Solution: Tesla Service now uses reinforced butyl patches (frequently called "flea tape") to secure the sensors permanently. Owners can also use "Override" on the screen (press and hold) to force the door open if it detects a "ghost."

Upper Hinge & Spine "Groaning",
Cause: The primary and secondary motorized struts in the "spine" of the car bear significant weight. Lack of lubrication or grit in the hinges leads to a rhythmic clicking or groaning sound during operation.
Solution: Mobile technicians apply specialized non-petroleum silicone grease to the hinge points. If the sound is metallic and loud, it usually indicates an actuator motor failure requiring a full strut replacement ($600–$900).
"The Rainforest" (Water Ingress),
Cause: Rainwater pools on the roof glass; when the door opens, the seal design—if slightly deformed—allows that water to spill directly onto the second-row passengers.
Solution: Tesla updated the seal design in late 2024. For older units, a common DIY fix is adding a 40cm EPDM rubber weatherstrip on top of the factory seal to create a more effective "gutter" to channel water toward the rear.
Sloped Driveway "Clipping",
Cause: When the car is parked on an incline (left-to-right slope), the frame flexes slightly. This can cause the door to clip the rear quarter panel or adjacent trim as it opens, leading to chipped paint.
Solution: Tesla Service can adjust the hinge shims and striker plates to increase clearance. A "Service Mode" calibration is also required to ensure the sensors account for the door's weight shift on uneven ground.
Latch "Cinch" Failure,
Cause: The small motorized "cinching" latch that pulls the door tight for the final half-inch often fails or loses its timing, causing the door to pop back open slightly after attempting to close.
Solution: Replacing the cinching actuator motor or the latch assembly. A software update (2025.44.1 or newer) improved the "handshake" logic between the door and the latch to reduce these errors.
