So, further update ....
Spoke to Nissan, who confirmed there was no recall for this, but rather the indicators were supplied to allow you identify if the nuts had been correctly tensioned and re-tensioned.
The official process is to check them by hand, tension in sequence to 60Nm, then tension in sequence to 133Nm.
According to Nissan, the only reason they come loose is if they are not tensioned correctly as per this process.
Spoke to the tyre place about this, and their process is to tighten by hand, then use the ratchet gun to tension them in sequence and then check them by hand. This is not tensioned specific to manufacturer specification, nor is it done in the two steps as recommended by Nissan.
However, they says that because it took 2 weeks to come loose, and because of the Nissan 'recall' (they insist on calling it that) they will only offer us $300 towards the $2000+ work that is required.
As you can imagine, not overly impressed, and I will certainly not be using TyrePower Gawler again. They also belong to the Cluse Bros chain here in SA.
While I know this is a known issue, it's interesting that the wheels were fine for 10months, and then within 2weeks of being rotated & balanced, we have issues!
Still planning to take it further! Will see what happens
