INFINITI QX50 Maintenance Schedule

3,750 miles(6,000 km), or every six months: No standard maintenance, is required, however, there is Severe Maintenance, which contains:

• Inspection of: brake pads and rotors, exhaust system, propeller shaft (all-wheel drive, or AWD, models), drive shaft boots, steering gear and linkage, axle and suspension parts, horn, lights, signals, wipers, rear hatch/hood lift supports, all fluids inspected (engine, wiper, brake, power steering, coolant), engine drive belt and hose inspections, engine air filter, suspension components (shocks, subframe, tie rods), differential and fluid (AWD models), Battery terminals and cables, battery test, tire pressure, treadwear, and depth.

7,500 miles(12,000 km), or every 12 months: Here is the first appearance of a Standard Maintenance menu, which has some repetition that includes:

• Inspection of: Brake lines and cables, brake pads and rotors, CVT transmission fluid, propeller shaft (AWD models), differential gear oil (AWD models), transfer case oil (AWD models), drive shaft boots, horn, lights, signals, wipers, rear hatch/hood lift supports, all fluids inspected (engine, wiper, brake, power steering, coolant), engine drive belt and hose inspections, engine air filter, suspension components (shocks, subframe, tie rods), differential and fluid (AWD models), battery terminals and cables, battery test, tire pressure, treadwear, and depth.
• Services performed: Replace engine oil and filter and rotate tires

11,250 miles(18,000 km), or every 18 months: Standard Maintenance includes:

?Inspections of: Intelligent Key battery, all fluids inspected (engine, wiper, brake, power steering, coolant), engine drive belt and hose inspections, engine air filter, suspension components (shocks, subframe, tie rods), differential and fluid (AWD models), battery terminals and cables, battery test, tire pressure, treadwear, and depth.

?Services performed: Replace in-cabin microfilter

These first three milestones show elements of service that will routinely appear, so it covers a wide range of milestones. However, we’re going to give you a glimpse into the far future of your vehicle to see how it ends.
