Service Schedule for your Grand Cherokee

After the first 8,000 miles or six months, whichever comes first, you should bring your Grand Cherokee in for its first service. This includes an oil and filter change, a tire rotation, and a careful safety check. Changing the engine oil and filter will allow the engine to continue running smoothly and efficiently by reducing friction, preventing overheating, and removing any contaminants from the engine. Meanwhile, a tire rotation is recommended to be performed with each oil change, as it will help prevent uneven and premature tire wear. As time goes on, these services should be performed at the same 8,000-mile interval. In addition to these routine services, the technician will also check your Grand Cherokee's essential components as a precaution. These include the steering and suspension system, braking system, CV joints, and exhaust system for any premature wear and tear. 

Your second oil change and tire rotation should take place at around the 16,000-mile mark. At this point, you should also have both of your Grand Cherokee's air filters checked. The first is the engine air filter, which cleans out the air that enters your engine. This can become clogged with dirt and debris, resulting in decreased airflow, which, in turn, causes a decrease in fuel efficiency and engine performance. Next is the cabin air filter, which cleans the air that enters the cabin. If this becomes clogged, it can have a negative impact on the air circulation and begin to allow dust particles into the cabin. Having these filters checked is especially important if you often drive on dirt roads or use your Grand Cherokee for off-roading. 

If you haven't replaced the air filters by the 32,000-mile service, you should do so. This service is also a good time to have your engine's spark plugs inspected and replaced if necessary. Spark plugs can become contaminated with carbon on the coils, leading to a misfire. A cylinder misfire is when the spark plug for one of the cylinders doesn't provide enough spark to ignite the fuel/air mixture adequately. This decreases the engine's performance and triggers the check engine light. At the 32,000-mile service, you should also have your Grand Cherokee's disc braking system inspected to ensure that the rotors and pads are still in good shape to provide optimal stopping power.

The services mentioned above should be performed again at 64,000 miles. If the spark plugs weren't replaced at the 32,000-mile service, Jeep recommends replacing them no later than 50,000 miles. Around the 64,000-mile mark is when brake pads and rotors are due to be replaced under normal driving conditions. However, if you spend much of your time driving in stop-and-go traffic, you may have already had them replaced. A technician should also check your Grand Cherokee's gearbox fluid. Over time, the fluid that lubricates the gears in your Grand Cherokee's transmission, front differential, transfer case, and rear differential can break down and become contaminated with metal shavings. If this is the case, the fluid should be drained and replaced. However, these fluids should be checked more frequently if you use your Grand Cherokee for towing or off-roading. 

Approaching a 100,000-mile odometer reading, you've likely developed good routine maintenance habits for your Grand Cherokee. However, ensuring its smooth operation beyond 100,000 miles adds more services. The 96,000-mile mark is a good point to have a technician take a close look at the hoses and lines that distribute fuel, brake fluid, and coolant to the appropriate places. Over time these hoses and lines can begin to corrode, becoming susceptible to leaks and tears. Additionally, a close inspection of your braking system, including the fluid, lines, calipers, pads, and rotors, should be in order at this service. The technician should also take a look at the vehicle's cooling system to ensure the engine isn't at risk of overheating.
