Tesla Adds Aero-Fin Side Repeater Cameras to the Cybertruck to Fight Rain and Road Spray
Share
Tesla has quietly redesigned the Cybertruck's side repeater camera housings, adding sculpted ridges and a sharp vertical fin that use passive aerodynamics to sweep rainwater and road spray away from the lens. Lead Cybertruck engineer Wes Morrill shared the change on X on September 9, giving owners a close-up look at the new fender inserts — and confirming the redesign adds no extra cost to build.
What happened
Tesla doesn't wait for model-year changeovers to update hardware. Parts get revised as soon as better engineering is validated and existing stock runs out, and the latest example is the Cybertruck's side repeater camera. Morrill explained that Tesla regularly tweaks components for cost, serviceability, and performance, and that the new repeater housing uses passive aerodynamics to disrupt airflow — channeling water and spray away from the camera lens while you drive.
A side-by-side of the old and new fender inserts shows the difference clearly. The original camera assembly sat completely flush inside a smooth, triangular indentation in the black wheel arch cladding. The revised housing adds sculpted aerodynamic channels and a sharp vertical fin right next to the lens. That lip disrupts the high-speed air rushing along the front fenders, deflecting water droplets and road grime before they can coat the glass.
Why it matters
Clean camera lenses are non-negotiable for Tesla's driver-assistance suite, and even more so for Full Self-Driving (Supervised) in heavy rain. The Cybertruck's front bumper camera has its own dedicated washer, but the side repeaters don't have integrated fluid spray nozzles. Tesla has rolled out dedicated camera washers on the purpose-built Cybercab and on retrofitted Model Y robotaxis, but that plumbing hasn't reached production Cybertrucks yet.
So instead of adding pumps, lines, and wiring, Tesla solved the problem with clever plastic molding. It's a good example of how the company keeps its vision system clearer in bad weather without adding mechanical complexity — or cost. If the new housings prove effective, Tesla could bring the same trick to other vehicles down the road.
Part of a steady stream of rolling changes
This camera tweak is one of many mid-cycle revisions across the Cybertruck and Tesla's wider lineup. Just last month, Tesla upgraded the Cybertruck underbody with carbon fiber composite trays in place of stamped aluminum panels, improving underside durability during off-road rock crawling. The rolling hardware updates also arrive alongside shifting pricing: a couple of weeks ago Tesla raised Cybertruck prices by $5,000 across all dual-motor configurations, pushing the truck's starting price to $74,990.

What this means for Cybertruck owners
If your Cybertruck was built before the changeover, you're not getting the new fins retroactively — Tesla swaps parts in as inventory turns over, so this is a build-date thing, not a service bulletin. The practical takeaway for existing owners is the same one the engineering points to: your repeater lenses have no washers, so keeping them clear is on you. A quick wipe with a clean microfiber before a long rainy drive genuinely helps, and it's worth checking the repeaters any time you get an obstructed-camera alert.
It's also a reminder that the Cybertruck's camera system is doing a lot of work — for Autopilot, FSD (Supervised), Sentry Mode, and dashcam recording alike. If you want that footage saved reliably, a proper high-endurance drive and a clean power source matter. Our 4-in-1 glove box USB hub for the Cybertruck includes a dedicated USB 3.0 dashcam port so your storage drive stays powered and out of the way.

The bottom line
Tesla added a small plastic fin to the Cybertruck's side repeater camera housings and solved a real wet-weather visibility problem for free. It's a minor part with an outsized effect on how well the truck's vision system sees in rain — and a neat illustration of Tesla's continuous-improvement approach to manufacturing. Owners of earlier trucks won't get the upgrade, but a clean lens does most of the same job.
