Forum posters have cataloged various issues with the Cybertruck's windshield wiper motor2. These problems include the motor not working at all, the motor quickly burning out after minimal usage, and the wiper moving from left to right on its own when exceeding speeds over 65mph3. Some users have also mentioned that the wiper does not reach a good chunk of the glass in front of the passenger. These issues have led to concerns about the wiper's functionality and safety, especially during rainy conditions.
Cybertruck owners have reported several safety concerns regarding the unique, single-piece windshield wiper design2. These concerns primarily stem from issues with the wiper motor, which have led some owners to believe that it is a safety issue. Some owners have experienced the motor not working at all, while others have reported the motor quickly burning out after minimal usage. Additionally, the windshield wiper not working makes driving in the rain dangerous, as it obscures the driver's vision. Some owners have suggested applying Rain-X to the windshield as a solution, a chemical product that makes water bead up and run off the glass, making the wiper less relevant and less distracting during rain.
The poster named Greyfish stated that all Cybertruck deliveries have been halted for about a week due to a new safety issue discovered with the windshield wiper motor.
