I suggest that you read the OWNERS MANUAL
the dealerships always try to tell you that things are due, long before they are
here is the manual online, just fill in the blanks & d/l the PDFile
30,000 mile spark plug replace
Inspect the front and rear axle fluid, change if using your vehicle for police, taxi, fleet,
off-road or frequent trailer towing.
Otherwise the manual never reads that the differential fluids needs changing
I didn't see any scheduled maintenance for the transmission, but i may have missed it
