I had this problem, it seems like it was always there. Would get a creak coming from somewhere in the dash when manoeuvring at low speeds and big steering lock, especially backing up.
My dealer fixed it and their explanation of the issue is copied below (translated from Chinese).
“The technical manager said that our whole car body is made of aluminum. After a period of intense twisting and driving, there will be some energy needs to be released in some places. There will be a little deformation in some body connection places, such as the contact point of the connecting bracket. This is the reason why the connection point produces squeezing noise. At this time, you need to loosen the screw, then reset the bracket to the standard position, and then tighten the screw, so that they all return to the original state.”
So basically it needs various fixings to be backed off and then tightened again. It worked for me, no more creaks since they did it a couple of weeks ago.
