You can also feel safe in the knowledge that every single car coming from the assembly line in Alabama is road tested immediately. Every odometer coming from the factory has at least 2.3 miles on the odometer and is thoroughly scrutinized. Hyundai accepts no squeaks, squeals, or rattling from any of their vehicles. They also have more than 250 welding robots, and additional robots that check the work of those welding robots. Complex optical sensors at these check stations measure tolerances, ensuring tight welds and minimal gaps between panels.
