Despite software refinements earlier in 2025, the Cybertruck’s oversized windshield wiper—nicknamed the “Gigawiper”—continues to pose problems.
A Tesla Service notice shared by an owner confirms an active Engineering Investigation into the wiper’s performance. In the meantime, Tesla has been replacing entire wiper arm assemblies rather than waiting for a permanent fix. Many early Cybertrucks received an upgraded V2 arm to replace the original V1; some service staff report a V3 arm is already in early testing.
The issue stems from the Cybertruck’s uniquely large, four-foot single blade designed to sweep its broad, flat windshield. That design has generated recurring complaints. Although a June 2024 recall addressed faulty wiper motors on early units, owners continue to report cleaning and reliability problems—particularly in cold or salty conditions. Common reports include:
- Improper stowage at high speed, where the blade sits at an incorrect angle and slightly intrudes into the driver’s view.
- Inadequate contact across the blade’s sweep, especially at the top and midstroke, which can leave the area over forward-facing FSD cameras and the passenger side uncleared and degrade camera availability.
- Washer system faults, often caused by kinks in hose assemblies or loose fittings, leading to dribbling or leaking instead of proper spray.
Tesla attempted to mitigate some behaviors via over-the-air updates (notably 2025.2.8), which refined wiper logic to improve motion and stow behavior. However, the new service document indicates software changes alone are unlikely to fully resolve the problems. The company’s investigation suggests a probable mechanical deficiency in the arm assembly—possible causes include spring tension, hose mounting, or structural rigidity—rather than purely a calibration issue.
Owners experiencing wiper problems should log a service ticket. Replacing the wiper blade can address some symptoms but not all. Tesla’s engineering team appears to be developing revised parts while the investigation continues, and the service note says customers will be contacted when a remedy is available. Engineering Investigations can precede manufacturer-initiated recalls, so further actions may follow.
