Plastic flexing

Has anyone been able to fix the horrendous flexing noises? Firstly I understand plastic flexes when warmed, which is likely in Australian heat. That’s not what this post is about. The noises I’m dealing with are far in excessive of normal noises you’d expect at this price point. The ADAS head unit, or the trim around it makes a loud flexing noise that I can hear over music. It sounds more like cracking…. and it’s both distracting and embarrassing. BYD always claim “we didn’t take it for a long enough drive to hear it”. I’m hoping someone has a fix, like a certain noise buffer/insulator they’ve found. Also, aircon… the fan blades creak A LOT! Anyone with any experience getting the blades lubricated?
