What happens if you skip it
- Delaying 9-speed transmission fluid service beyond 100,000 miles significantly increases risk of harsh shifting, slipping, and premature torque converter failure requiring $4,000+ replacement.
- Neglecting SH-AWD rear differential fluid changes can cause the electromagnetic clutch packs to overheat and fail, disabling rear torque vectoring and requiring $2,500+ repair.
- Skipping brake fluid exchanges allows moisture absorption that corrodes the ABS modulator and brake calipers, leading to spongy pedal feel and potential $1,200+ ABS unit replacement.
- Ignoring spark plug replacement past 120,000 miles causes misfires that damage the catalytic converters, triggering check engine lights and potential $2,000+ converter replacement.
- Deferred coolant service leads to internal corrosion and water pump seal failure, risking overheating and head gasket damage on the aluminum V6 block.
Common issues at higher mileage
- 60,000+ mi
- 9-speed transmission may exhibit delayed 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 at $400-$700 per side.
- 100,000+ mi
- VCM (Variable Cylinder Management) system can cause excessive oil consumption and fouled spark plugs on cylinders 1, 4, and 6 if not using full-synthetic oil.
- 120,000+ mi
- Electric power steering rack bushings can wear, causing steering play or clunking; EPS motor may also develop faults requiring replacement.
- 150,000+ mi
- Timing chain tensioner and VTC actuator wear may cause cold-start rattle; while the chain itself is durable, these components may require service at higher mileage.
