Specifically the soft close function of it?
Ours stopped "soft closing" around a year after purchase (even though it was technically installed and used for probably a month less than that; I know warranty starts from purchase date though).
Warranty is only one year and the manufacturer has refused warranty claim because its just outside of warranty.
I emailed ACCC the same question, and they just responded with a lengthy template response, not specific to my enquiry.
Thanks in advance.
