Ok, so a bit of an update on my original post.
My car went to the dealers Friday before last and the master tech experienced exactly the same issue that I had when he pushed the button. he also mentioned that he had never pressed one before.
I left the car with them, as there were a couple of other things that had to be sorted and had updates during the week. It was pushed over to Sweden for guidance and a couple of things were tried but to no avail.
i decided that I would go back on Friday just gone to collect the car as it appeared it was going to take some time. On arrival I spoke to the tech again and he explained what had been tried and it had been escalated in Sweden.
We were then joined by a member of the management team and I explained the situation to him. He suggested that he go and push the button on his XC90, and yes his did exactly the same. Following further discussion he offered, later that afternoon, to get the button pressed in all of the demonstrators they had on site and he would advise what had happened.................
I had an email from him promptly that afternoon and they all did 'broadly the same thing'.
They have subsequently had contact back from Sweden and been advised that it is a 'provider issue' and are continuing to investigate. I believe from 'squints' woes that is what he was advised by his dealer.
So, it appears that this major safety issue, highlighted by squint originally, is more prevalent than was originally thought.
I believe, as a major safety feature of the car, it needs to be tested, wether that is by yourselves or taking your car back to the dealer and asking them to do it.
I am not sure how many people have to report this as an issue before it becomes a recall, of course when they finally have a fix for it, but the more it is tested the more robust the 'sample'
It may well be worth having a 'poll' on the forum to start to put some figures together ?????????
