Tesla Opens Probe Into Cybertruck’s Massive ‘Gigawiper’

Tesla has opened an official Engineering Investigation into ongoing issues with the Cybertruck’s massive windshield wiper, suggesting the long-running “Gigawiper” saga is far from resolved. Despite earlier software tweaks aimed at improving its behaviour, new service information indicates Tesla now believes there may be a deeper hardware problem at play (via Not a Tesla App).

According to a recent Tesla Service message shared by a Canadian Cybertruck owner, the company has begun actively investigating the Gigawiper’s performance and, in some cases, is replacing entire wiper arm assemblies while a permanent fix is developed. Tesla previously swapped out the original V1 wiper arm on many early Cybertrucks with an updated V2 assembly, but service staff have reportedly told owners that a V3 version is already in early testing.

The Cybertruck’s wiper is unlike anything else on the road. At roughly four feet long, it’s the largest single windshield wiper ever fitted to a passenger vehicle, designed to clear the truck’s huge, flat windshield in one sweep. That ambitious design, however, has proven troublesome in real-world use.

Early Cybertrucks were recalled in June 2024 due to faulty wiper motors, but owners have continued to report problems well beyond that fix. Complaints range from improper stowage at highway speeds — where the wiper sits slightly in the driver’s field of view — to poor contact across large sections of the windshield. Many owners say the blade fails to adequately clean the area in front of the forward-facing FSD cameras or the passenger side of the glass, often leaving Full Self-Driving unavailable in snowy or salty winter conditions.

There have also been reports of washer fluid issues tied to the wiper assembly itself, including kinked hoses or loose fittings that cause fluid to dribble or leak instead of spraying properly.

Tesla has attempted to address some of these problems through software. Earlier this year, an update improved the wiper’s logic and stowing behaviour, making its movement more precise. However, the new Engineering Investigation strongly suggests software alone isn’t enough. Tesla says it is continuing to study the issue and will contact affected owners once a solution is ready.

While an investigation doesn’t automatically mean a recall, these probes often precede broader manufacturer-led fixes. Earlier this fall, Tesla recalled more than 6,000 early Foundation Series Cybertrucks due to issues with the optional off-road lightbar. For now, Tesla is advising owners experiencing issues with the Gigawiper to submit a service request. In some cases, installing a fresh wiper blade may help, but a full hardware revision appears increasingly likely.
