In December 2018 I received a letter from Holden about a Safety Recall for a power steering problem for my 2014 Holden Calais, "which may result in loss of power steering assistance". We are elderly and such an issue could be disastrous for us. I wrote a letter to the GM customer contact asking for urgent attention for this reason. I received no reply. I have resent the letter on 30 April and 30 May, but still no reply. The selling dealer has closed and when I rang Holden customer care I had no help either. In my desperation should I contact the ACCC?
