This issue frustrates the hell out of me and has done for years. I am sure that people wouldn't mind a few things going wrong with their car if the dealers actually cared about their service and look after the customer.
Quality control is also an issue as well, I know the car is made to a price but to have the same sorts of issues after 3 or 4 model releases, .
Holden clearly has to sort out its dealers, most people will avoid them at all costs. Are you listening Holden. No, you never do. The marketing department will sort it out.
