SpaceStar steering sporadically extremely heavy BJ2017

Dear Forists! I need your opinion or feedback! We have a “problem” with our SpaceStar BJ2017. It is mainly driven by my wife. When I sometimes sit in the box, I always notice immediately how extremely difficult the steering is. Especially when it comes to shunting, you sometimes have the feeling that the complete steering support is missing…. a feeling like with my Opel Corsa A (it really had no steering support). If you are on the road for a while, g Is there nothing to complain about (except the weak reserve power, but this is probably a series). Then everything works as usual even at slow speeds….or suddenly stop (but only driving very slowly or mainly at park maneuvers). It is addressed by me at every customer service…seemingly everything is OK. But that can’t be so with a modern car? Thank you for your feedback/experiences! e and are regularly at a Mitsubishi dealer/workshop. Many greetings from the south
