What happens if you skip it
- Delaying 9-speed transmission fluid service beyond 90,000 miles can cause harsh shifting, slipping between gears, and premature clutch pack wear requiring $4,000+ transmission replacement.
- Neglecting SH-AWD rear differential fluid changes leads to bearing noise, overheating during aggressive cornering, and potential failure of the torque-vectoring system.
- Skipping brake fluid exchanges allows moisture contamination that corrodes ABS modulator internals, causing spongy pedal feel and expensive ($1,200+) ABS unit replacement.
- Ignoring spark plug replacement past 105,000 miles results in misfires, reduced fuel economy, and potential catalytic converter damage from unburned fuel.
- Overdue engine oil changes on the direct-injection V6 cause carbon buildup on intake valves, leading to rough idle, reduced power, and costly walnut-blasting service ($400-$600).
Common issues at higher mileage
- 60,000+ mi
- 9-speed transmission may exhibit hesitation or harsh 2-3 upshifts; software updates and fluid service often resolve early symptoms.
- 80,000+ mi
- Front lower control arm bushings wear prematurely, causing clunking over bumps and requiring replacement of the entire control arm assembly.
- 100,000+ mi
- Engine mounts (especially front and rear) deteriorate, producing vibration at idle and during acceleration in this heavier SUV platform.
- 120,000+ mi
- Infotainment system touchscreen may develop unresponsive zones or require multiple presses; software updates or screen replacement may be needed.
- 150,000+ mi
- SH-AWD rear differential bearings may develop whine or growl if fluid service was delayed; early attention prevents complete differential failure.
