It's supposed to be by ownership date (warranty start date), but I go from the build date and never have a problem. The brake flush is every 2 years, the coolant is every 3 years.
Some dealers will tell you it's not included, this is FALSE, it is regularly scheduled maintenance and is included in the maintenance commitment plan. I wouldn't expect them to do the brake flush at this service, amybe the next service. You CAN'T bring it in at the "exact" 2 year interval just to have this done, it is done only with an FSS service, not on a seperate ticket, so you may run over on time just a bit.
The brake pads at 24K? maybe, varies alot depending on how the car is used.
