My dealer said I need to change my transmission and brake fluid. Also, what about coolant, rear differential fluid? My mileage is 35000 on a 2010 that I have had 2.5 years. The owners manual says brake fluid every 3 years. I don't see a mileage for the other fluids. Maybe thats because it depends if they look dirty. Problem I have is I don't believe my dealer ever since they told me to have the fuel injectors flushed at 15,000 miles.
