Had book for air bag lights problem , the service team
Could not find actual issue for the problem they just retrieve the error code costing $170 for 15 min job , the same job can do any auto electrician with $50
They have no idea what s the real problem , I booked service for finding actual cause and cost to fix the problem , booked appoint for 9.am they took car at 10.15 am and returned 10.30am, best job ever in the world , $680 per hr , this is the real reason people are not going for dealership for service it s not genuine cost really disappointed day with heritage motor service Maitland,
