I just got a notice in the mail for a 15K mile service from my local dealer. For once their estimate isn't too far off the mark on what my mileage is.
I normally will do my own oil changes (every ~5000 miles), using Mobil 1, and if I feel it's needed I'll rotate the tires, and check everything else out too. I've had no issues in the past.
Below is what they say is done in the 15K service:
Change oil/ filter, check windshield wipers/ washers
check drive train fluids, check parking brake adjustment
service automatic transmission, inspect steering rack & pinion,
inspect drive shaft boots, inspect brake linings,
check tire condition/ pressure, inspect coolant system & radiator,
inspect exhaust piping & mountings, check battery electrolyte level,
lubricate steering knuckle, lubricate chassis, steering & propeller shafts, inspect steering linkage, inspect ball joints & dust covers, inspect air filter, replace drain plug gasket, rotate tires, check door latches & hinges,
check drive belts & tension, check shocks & struts, check interior/ exterior lights, check all engine fluids, inspect cabin air filter.
I haven't noticed any issues. I know that my air filter probably needs replacing, and I have a few issues with one of my tires (hit a curb a while back and put in a nice slice in the sidewall).
They claim that I can get all of the above for $119.95 and does not include synthetic oil or HAZMAT fees. I guess is it worth the $$$$ to just let them do it? I'm sure they'll come up with something that needs to be done (they always do)
