My 2016 RRS V8's bumper to bumper warranty is ending very soon. I have 49,700 miles and will soon hit 50K on the odometer by next week. I have an appointment for service next week to have a musty smell from my a/c checked and my passenger side one-touch up/down has to be pressed twice sometimes to work. Other than that its been running good (knock-on-wood). Anyone else with high mileage recommend anything I can have checked preventive? I know the dealer will only fix/repair something if it is broken but wondering if anyone had anything go around the 50K mark.
