I came in to say this. "Oncle Tom" translates to "Uncle Tom" in English, and in the US it has an extremely derogatory meaning towards African Americans. It's essentially a "black man that sold out to the White Man".
The name choice probably wasn't motivated by this, but it's an unlucky choice if the goal was to grow in North America, similar to the Chevy Nova, which in Spanish was equivalent to "No Go".
