Tesla has recently launched an official Engineering Investigation into the ongoing issues surrounding the Cybertruck’s massive windshield wiper, indicating that the problems with the “Gigawiper” are far from being resolved. Despite previous attempts to improve its performance through software tweaks, new service information suggests that Tesla now believes there may be a deeper hardware issue at play.
According to a recent Tesla Service message shared by a Canadian Cybertruck owner, the company is actively looking into the performance of the Gigawiper and, in some cases, is replacing entire wiper arm assemblies while a permanent solution is being developed. Tesla had previously replaced the original V1 wiper arm on many early Cybertrucks with an updated V2 assembly. However, service staff have informed owners that a V3 version is currently in early testing.
The Cybertruck’s windshield wiper is unlike anything seen on the road before. Measuring approximately four feet long, it is the largest single windshield wiper ever installed on a passenger vehicle, designed to clear the truck’s massive, flat windshield in a single sweep. Despite its ambitious design, the Gigawiper has faced challenges in real-world use.
Early Cybertrucks were subject to a recall in June 2024 due to faulty wiper motors, but owners have continued to report issues beyond the initial fix. Complaints range from improper stowage at high speeds, where the wiper obstructs the driver’s view slightly, to poor contact across large sections of the windshield. Many owners have noted that the wiper blade fails to effectively clean the area in front of the forward-facing FSD cameras or the passenger side of the glass, leading to Full Self-Driving being unavailable in snowy or salty winter conditions.
Reports have also surfaced regarding washer fluid issues related to the wiper assembly itself, such as kinked hoses or loose fittings causing fluid to dribble or leak rather than spray properly.
While Tesla has attempted to address some of these issues through software updates, such as improving the wiper’s logic and stowing behavior earlier this year, the new Engineering Investigation suggests that software alone may not be sufficient. Tesla is continuing to investigate the problem and will reach out to affected owners once a solution is developed.
Although an investigation does not automatically result in a recall, these probes often precede broader manufacturer-led solutions. Earlier this year, Tesla recalled over 6,000 early Foundation Series Cybertrucks due to issues with the optional off-road lightbar. For now, Tesla is advising owners experiencing problems with the Gigawiper to submit a service request. In some cases, installing a new wiper blade may offer temporary relief, but a full hardware revision seems increasingly likely in the future.
