<div id="readability-page-1"><div> <p>Tesla has quietly opened an engineering investigation into the Cybertruck’s oversized windshield wiper, fondly (sometimes not as fondly) referred to by owners as the “gigawiper.” The investigation was revealed through a service invoice shared by a Cybertruck owner, indicating that the issue has been escalated beyond routine service repairs and into Tesla’s engineering pipeline.</p> <p>According to the service notes, Tesla technicians verified the customer’s concern and proceeded to diagnose and replace the wiper arm assembly. After the replacement, proper fitment and operation were confirmed. However, the notes go a step further, stating that wiper performance is now under “active engineering investigation” and that the customer will be contacted once a broader solution becomes available.</p> <figure><div>  </div></figure> <p>That language is significant. Tesla service documentation typically limits itself to the immediate repair performed, so explicit mention of an ongoing engineering investigation suggests the issue may extend beyond a single vehicle or defective component. It also implies that Tesla engineers are assessing whether the problem is related to design, software control, hardware tolerances, or environmental factors unique to the Cybertruck’s large, steeply raked windshield.</p> <p>The Cybertruck’s gigawiper is unlike anything else on the road today. Designed to sweep the truck’s massive windshield with a single blade, the system was engineered to reduce complexity while still clearing a large viewing area. While visually striking, that unconventional approach also introduces new challenges, including blade pressure distribution, arm flex, motor torque, and performance at highway speeds or in heavy rain and snow.</p> <figure><div>  </div></figure> <p>Some owners have reported streaking, uneven clearing, or reduced effectiveness in certain conditions. While these complaints are not universal, the fact that Tesla has initiated an engineering review suggests the company is taking the feedback seriously as Cybertruck deliveries continue to ramp up.</p> <p>For Cybertruck owners, the investigation should be seen as a positive step. It confirms Tesla is aware of the concern and actively working on it, rather than treating each case as an isolated repair.</p>   </div></div>
