I was just reading through the following comment with interest: https://www.ozbargain.com.au/comment/12108423/redir, and wanted to hear back from folks with deeper knowledge of the ACL literature on my interaction with Apple (National) Tech Support (aka Apple Care Phone Support):
30 June 2021 - Purchase Apple AirPods Max (MGYN3ZA/A) from Wireless1 (for a family member). I did not receive the product until mid-July 2021.
I noted later that warranty already stared on 22 June 2021 (https://checkcoverage.apple.com/au/en/?sn=XXXX). Apple Care phone support informed me that they can only restart the warranty to the date of purchase, and not the date of delivery. I didn't bother submitting paperwork for an extra 8 days of warranty.
30 December 2021 - After updating to the latest iOS and update the firmware on the device, it started playing up. It would randomly disconnect, and fail to reconnect until you reboot the device. Sometimes, it had to be hard reset every other day.
03 February 2021 - Booked a genius bar appointment at my local store. They examined the unit for any physical damage, and informed me they need to ship it off to an offsite repair facility, as they only repair Macs and iPhones on-site.
15 February 2021 - Device repaired. They replaced both drivers, and hence the device now has a new serial number. However, no one could tell me what was wrong with the original components. Anyway, before leaving I was told by the Apple Genius Bar member that the replacement comes with another 12 months warranty.
Upon checking the new serial number recently, I see that the warranty end date is still stuck at 22 June 2022. I contacted Apple Tech Support, and managed to get hold of someone from Sydney after passing through several Filipino call centre agents who were not able to assist. They were absolutely adamant that the warranty does not restart from the date of repair / pick up.
QUESTION: Should the warranty restart from the date of replacement once a device has been replaced due to a manufacturer's fault?
Call the ACCC - they can tell you.
