2022 Jeep Grand Cherokee Factory Maintenance Schedule

Quick Reference: 2022 Jeep Grand Cherokee Maintenance

Severe-Duty Schedule

If you frequently use your Grand Cherokee under what the manufacturer deems "severe" conditions, you'll need to adjust your maintenance schedule accordingly. These conditions include:

• Towing or hauling heavy loads
• Frequent short trips (under 5 miles)
• Operating in extremely dusty or sandy environments
• Extensive idling or stop-and-go driving
• Living in very cold or hot climates

Under these conditions, your Oil Life Monitoring System will be your best guide, likely indicating a need for an oil change much sooner than the 10,000-mile maximum, often in the 3,500-5,000 mile range. Additionally, expect to replace air filters and inspect brakes, tires, and suspension components more frequently. For 4x4 models used off-road, axle and transfer case fluid inspections should be performed after every session that involves fording water.

Known Issues by Mileage for the WL Generation (2021+)

The "WL" generation Grand Cherokee is still relatively new, but early data and owner reports have highlighted a few areas to watch:

• 20,000-40,000 Miles: Some owners have reported premature software glitches and infotainment system issues. These are typically resolved with software updates from the dealer. There have also been some reports of issues with the Quadra-Lift air suspension, so a thorough inspection during service is wise.
• 60,000+ Miles: While not widespread, be mindful of any unusual transmission behavior. The ZF 8-speed is generally reliable, but ensuring fluid levels are correct and software is up-to-date is key. As with any direct-injection engine, be aware of the potential for carbon buildup, which can be mitigated by using high-quality fuel.
• 100,000+ Miles: This is where long-term wear items come into play. Accessory belts, tensioners, and water pumps are items to inspect closely. The 3.6L Pentastar V6 has a reliable history, but keeping the cooling system in top shape by performing the 150,000-mile flush is critical to prevent issues.

Estimated Cost per Service

• Basic Service (Oil Change, Tire Rotation): $100 - $180
• Intermediate Service (30k/60k mile intervals): $350 - $700 (Varies based on engine and drivetrain)
• Major Service (100k/150k mile intervals): $800 - $1,500+ (Depending on spark plugs, coolant flush, belts, etc.)

What You Can DIY vs. What to Leave to the Shop

DIY-Friendly:

• Engine Oil & Filter Change: Accessible for the home mechanic.
• Engine & Cabin Air Filters: These are typically very easy to access and require no special tools.
• Tire Rotation: Can be done with a good jack, jack stands, and a lug wrench.

Leave to the Professionals:

• Transmission & Transfer Case Service: Requires specific fluids, tools, and procedures to ensure proper fluid levels.
• Brake Fluid & Coolant Flush: These are sealed hydraulic systems that can be difficult to bleed and refill correctly without specialized equipment.
• Spark Plug Replacement: While possible for an experienced DIYer, the rear plugs on the V6 can be challenging to access. Given the long interval, it's often best left to a pro.
• Timing Chain Inspection: This is a major undertaking that requires significant engine disassembly.
