Regarding the steering or steering wheel, the most common failure has to do with a rattle. This has been reported by several users. For example, one of these owners says that when he heard this noise frequently, he had the vehicle checked, but both the shock absorbers and the pads were in good condition.

In the same forum, another user provides a clue as to what is causing this problem. As he relates, the rattle that occurs, especially when traveling on an irregular path, is due to the fact that the steering box cannot be adjusted (more than it already is).
