Factory Service Intervals

Jeep’s recommended maintenance schedule for the 2021 Grand Cherokee is designed to keep your vehicle in optimal condition. Regular servicing ensures longevity, safety, and preserves your warranty. Here’s a breakdown of key service items:

| Service Interval | Item to Service | Notes Every 10,000 miles (or 1 year, whichever comes first):

• Oil and Filter Change: Crucial for engine longevity. Use Mopar API Certified SAE 5W-20 or 5W-30 engine oil, depending on your engine (refer to your owner's manual). Pentastar V6 models typically use 5W-20, while the 5.7L HEMI V8 uses 5W-20, and the SRT/Trackhawk's supercharged 6.2L V8 uses 0W-40. Always use a Mopar oil filter or equivalent high-quality filter.
• Tire Rotation: Promotes even tire wear and extends tire life. Check tire pressure and inspect for damage.
• Brake Inspection: Check brake pads, rotors, calipers, and fluid level. Ensure proper functionality.
• Exhaust System Inspection: Look for loose connections, corrosion, or damage.
• Battery Inspection: Check terminals for corrosion and ensure secure connections.
• Coolant Hoses and Clamps Inspection: Look for leaks, cracks, or loose connections.
• Wiper Blade Replacement: Replace if streaking or chattering.
• Inspect all fluid levels: Including brake, power steering (if applicable), and washer fluid.

Every 20,000 miles (or 2 years):

• Cabin Air Filter Replacement: Improves air quality inside the vehicle. Especially important if you live in dusty environments or have allergies.
• Engine Air Filter Replacement: Ensures optimal engine performance and fuel efficiency.

Every 30,000 miles (or 3 years):

• Spark Plug Replacement (5.7L HEMI V8 and 6.2L Supercharged V8): Essential for maintaining ignition performance. The 3.6L Pentastar V6 typically has a longer spark plug interval (around 100,000 miles). Confirm your engine type with your owner's manual.
• Transfer Case Fluid Change: If equipped with 4WD. Use Mopar NV245/247/249/273/271/276/246 transfer case fluid, or equivalent. Specific fluid type varies by transfer case model.
