That be easier to believe if there weren't so many Model 3 and Y vehicles that are clearly the new ones (changed headlights/taillights) all around. I'm sure Elon's "political" salutes gave their sales some headwinds, but I'm inclined to think it is more like 15% less sales (Q4 2024 vs Q4 2025). The CyberTruck factory is operating at <20% capacity.
The biggest problems are: it costs ~2x what Elon said it would, it has less than half the range he said it'd have, and it has had 10 recalls in its short life.
The recalls have been for things as basic as: light bar falling off, exterior trim falling off, bed trim falling off, the acceleration pedal falling off, inverter failures. It paints a picture of a low-quality product that has a very premium price.
