Since its unveiling in 2019, the Tesla Cybertruck has sparked debates about its unique exterior, which consists of an exoskeleton made from ultra-hard stainless steel. One of the key selling points of the car is its corrosion-resistant body, but how true is this claim? This begs the question, will your Tesla Cybertruck rust? Continue reading for a deep dive into the materials, conditions, and factors that could impact the vehicle’s resistance to rust.
What Makes the Cybertruck Body Unique?
The car’s exterior is constructed from a high-quality 300 series cold-rolled stainless steel, the same material used in SpaceX rockets. This high-strength alloy provides several advantages, including:
- Corrosion Resistance: Stainless steel is known for its resistance to rust and oxidation, which is why it’s commonly used in industries like aerospace and construction.
- Durability: The car’s exoskeleton is designed to withstand dents, dings, and scratches better than traditional automotive paint.
- No Paint Required: Unlike traditional vehicles that rely on a layer of paint for protection, the bare metal finish on the Cybertruck is one of its defining features.
Can the Cybertruck Rust?
Yes, but under specific conditions. While stainless steel is highly resistant to rust, there are certain circumstances where it’s a possibility:
- Exposure to Salt and Moisture: If you live in a region with harsh winters or near the ocean, your Cybertruck will likely be exposed to road salt or salty air. Over time, chloride exposure can cause pitting corrosion, a localized form of rust that can affect stainless steel.
- Lack of Maintenance: While stainless steel doesn’t require painting, it still benefits from regular cleaning. Dirt, grime, and pollutants can trap moisture, leading to potential corrosion.
- Welding or Heat Damage: If any modifications or repairs involve welding, the heat can alter the stainless steel’s protective properties, making it more vulnerable to corrosion in affected areas.
NOTE: You may have seen some online buzz about Cybertruck vehicles appearing to rust with small spots of discoloration immediately after being exposed to rain. However, Tesla claims that this is simply rail dust, tiny iron particles that can be caused by sources of metal abrasion. These can typically be removed with cleaning using items like clay bars.

The Bottom Line
Will your Tesla Cybertruck rust? Tesla claims that the high-quality 300 series cold-rolled stainless steel is corrosion-resistant. However, that doesn’t make it immune to rust, as there are specific conditions that can cause the car to rust. If you take care of your Cybertruck and clean the exterior regularly using the correct materials, you can likely avoid rust in the long term.
