A recent entry in the Tesla Service Toolbox reveals that the Cybertruck contains the hardware required for Active Noise Cancellation (ANC) but the feature is disabled in software. The service diagnostic screenshot reads: “As of 30-Jan-2025, ANC software is not enabled on Cybertruck even though the hardware is installed.”
ANC is a signature comfort feature in Tesla’s flagship Model S and Model X. In those cars, six cabin microphones and accelerometers near the wheels monitor interior noise and wheel frequency. The audio system then generates anti-noise—phase-inverted sound waves—to cancel low-frequency road rumble and tire noise.
The Cybertruck appears similarly equipped, though it has four cabin microphones rather than six. That hardware presence indicates Tesla intends to support ANC in the vehicle, but has not yet activated it.
Why it remains disabled likely comes down to the Cybertruck’s unconventional acoustics. Its large, angular body and expansive glass canopy produce a very different acoustic environment compared with the Model S and Model X. Tesla also uses the truck’s unique castings to route subwoofer audio through internal voids in the frame to increase perceived bass—an architecture that complicates the generation and propagation of anti-noise. Additionally, the standard All‑Terrain tires produce different noise frequencies than the road-optimized tires used on other models, making cancellation more challenging.
Taken together, these factors suggest a nontrivial software and tuning effort is required to achieve satisfactory ANC performance in the Cybertruck—despite the vehicle already being relatively quiet.
For current owners, the takeaway is positive: the vehicle is effectively future-proofed for a comfort upgrade. Once Tesla completes the necessary tuning and validation, enabling ANC could be as simple as an over-the-air software update.
