I am driving a Toyota Sequoia. Built like a tank. Manufactured in Kentucky. The plant at the time was non union. The UAW is targeting them so who knows how the quality will be affected. For now, I have a keeper.
I think it comes down to the management, how the operations of the plant are designed and maintained, and the quality of the components, and whether the vehicles go together easily.
When toyota took over the Fremont Plant formerly operated by GM, things improved dramatically, even with largely the same UAW workforce.
