Why does the clock in my Hyundai keep going wrong?

I have a 72 reg Hyundai Tucson and the time and date on display, for no apparent reason, are incorrect. This has happened lots of times, and when I mention this to the Hyundai dealership, they say this also happens on other Hyundai cars. I've had this checked when car has been serviced & was told no fault has been found.

I'm fairly sure that this is also happening on many other Hyundai cars. Surely Hyundai as a motor company are aware of this issue and are looking into reason for this fault?

This fault does appear to be happening on a range of Hyundai cars, and one suggestion is that it is caused by the car switching off certain systems when parked in order to preserve the charge of the 12V battery. We would suggest running a software update, which you can find here: update.hyundai.com/EU/E1/updateNoticeList
