Falcon wing door defects can have multiple root causes (sensor calibration drift, hinge wear, actuator failure, latch component issues) that present similar symptoms. Diagnostic confidence depends on identifying the specific component, not just resolving the immediate behavior through recalibration.
Recalibration-only resolutions can recur after a period of normal operation. Recurrent issues warrant a diagnostic that examines whether the underlying components are within wear specifications, not just whether the calibration can be restored.

Out-of-warranty falcon wing door repairs are one of the larger Model X ownership cost considerations. Independent shops with body/electrical specialty experience can in some cases address these defects at lower cost, with the trade-offs noted in the warranty section.
