What changed for the 2018 Jeep Grand Cherokee

The 2018 Grand Cherokee versus 2017: what's different, from the factory charts and spec sheets.

Compared automatically from the manufacturer's trim feature charts, specification sheets, towing guides and the EPA's fuel-economy data for 2017 and 2018. The manufacturer reorganized this year's equipment chart, so features can't be matched line by line with last year's; trims, packages and powertrains above are still compared. Equipment varies by trim and market; confirm details on a specific vehicle.

Annual fuel cost assumes 15,000 miles a year at the EPA's fuel-price assumptions, so yours will differ. Range is total driving range on a full tank or charge.

Not a single number: the owner's manual refers to the tire and loading placard (driver's side B-pillar or the rear edge of the driver's door), which lists the pressures for your exact tire size and load.
Spare
Depends on equipment: compact spare, full-size spare, inflatable spare, or a tire service kit instead of a spare. The spare has no tire pressure sensor.

2018 Jeep Grand Cherokee maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

Schedule

A dot means the service is due at that mileage or after that many years, whichever comes first.

Service brakes, hydraulic: antilock/traction control/electronic limited slip: control unit/moduleNovember 7, 2024 · Campaign 24V838000

Chrysler (FCA US, LLC) is recalling certain 2018-2019 Jeep Grand Cherokee and Dodge Durango vehicles. A malfunction in the antilock-brake system (ABS) module may incorrectly illuminate the brake lights and disable the ABS and electronic stability control (ESC). In addition, the vehicle operator may be able to start and shift out of Park without the brake pedal being applied.

Risk: A vehicle that can be started and shifted out of Park without applying the brake pedal can result in a vehicle rollaway. Disabled ABS and ESC systems can reduce vehicle handling and control in certain driving situations.

Fix: Dealers will replace the integrated pressure transducer and update the ABS module software, as necessary free of charge. Owner notification letters were mailed December 16, 2025. Owners may contact FCA customer service at 1-800-853-1403. FCA's number for this recall is 94B.

Engine and engine coolingJune 8, 2023 · Campaign 23V411000

Chrysler (FCA US, LLC) is recalling certain 2014-2019 Ram 1500 and 2014-2020 Jeep Grand Cherokee vehicles equipped with 3.0L Diesel engines. The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.

Risk: An engine stall can increase the risk of a crash.

Fix: Dealers will update the powertrain control module software to maintain vehicle propulsion, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed August 3, 2023. Some owner notification letters were mailed October 31, 2023.

Service brakes, hydraulic: antilock/traction control/electronic limited slip: control unit/moduleJune 9, 2022 · Campaign 22V426000

Chrysler (FCA US, LLC) is recalling certain 2018-2019 Jeep Grand Cherokee and Dodge Durango vehicles. A malfunction in the antilock-brake system (ABS) module may illuminate the brake lights, and allow the vehicle to start and shift out of Park without the brake pedal being applied.

Risk: A vehicle that starts and shifts out of Park without applying the brake pedal can result in vehicle rollaway, increasing the risk of a crash without prior warning and/or injury to others outside of the vehicle.

Fix: This recall is replaced by NHTSA recall number 24V838. Vehicles already repaired under this recall will need to have the new remedy completed. The remedy includes updated HCU/ABS module software that prevents the HCU/ABS module from falsely reading pressure in the primary circuit.

Read for lake-effect country

Reading the 2018 Grand Cherokee data for Great Lakes roads

Lake-effect squalls, roads soaked in brine, potholes that open with every thaw and long Appalachian grades: driving in the Great Lakes states asks a lot of tires, batteries and undersides. These notes take the 2018 Grand Cherokee figures above and flag the ones that carry the most weight in Ohio.

Pothole season and the factory tire sizes

Smallest factory tire: P245/70R17. Freeze-thaw cycles break up asphalt across the Great Lakes states, and one jolt can knock the alignment out without leaving a mark on the wheel. If the steering wheel sits off-center or the Grand Cherokee wanders after a pothole, get the alignment checked before the tire edges wear. A winter set on 17-inch wheels also keeps salt off the originals.

The oil grade on a January morning

The 2018 Jeep Grand Cherokee fluids table lists SAE 0W-20 (3.6L), SAE 5W-20 (5.7L) and SAE 0W-40 (6.2L and 6.4L), with 6 qt (3.6L), 7 qt (5.7L), 8.3 qt (6.2L) and 7 qt (6.4L) per change. Lake-effect winters are full of short, cold trips: to work, to school, to the store and home again before the engine reaches temperature. That pattern is tough on oil, so let the oil-change indicator set the interval and never stretch it.

Starting in single digits

Battery care in this schedule: inspect it and clean and tighten the terminals as required at each oil change, and the spec sheet rates it at 650 to 800 cold-cranking amps. A battery that bakes through a Nashville or Memphis summer ages faster, then gets found out by the first hard freeze. Have it load-tested in fall rather than waiting for a slow crank.

Traction for snowbelt hills and hollows

This model year offers rear-wheel drive and four-wheel drive. In Ohio, the payoff comes in the first hour of a storm, before plows reach side streets, and on boat ramps slick with algae where a two-wheel-drive tow vehicle can spin. Keep the system's limits in mind on ice: driven wheels add grip for going, not for stopping or turning.

Trailer duty in the schedule

The schedule lists axle fluid service for frequent trailer towing, starting at 20,000 miles. Whether it is a fishing boat headed for the Ohio River or a pop-up camper bound for the Smokies, the extra heat of towing ages these fluids faster, most of all on long July climbs.

Ground clearance, snowbelt to hills

The spec sheet puts ground clearance at 8.1 to 10.8 inches. Height matters for salt too: a low underbody pushes through slush and packs it around lines and heat shields, where it sits for days. After a slushy week in Columbus, a run through an underbody wash clears out what the clearance couldn't avoid.

Fuel reserve for storm closures

Fuel capacity: 24.6 gallons. Lake-effect whiteouts can shut stretches of I-94 in Michigan or I-90 through the Ohio Snowbelt for hours, so keep the tank from running low between November and March. If you do end up stranded, a running engine for heat needs a tailpipe clear of snow.

Each spec in these notes is pulled from the tables above. The commentary on salt, snow, potholes and grades is general guidance for the Great Lakes states; the owner's manual remains the authority.

2018 Jeep Grand Cherokee questions

How much oil does the 2018 Jeep Grand Cherokee take?

With a filter change: 3.6L engine (SAE 0W-20, API certified), 6 qt / 5.6 L and 5.7L engine (SAE 0W-20, API certified), 7 qt / 6.6 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.

When is the first scheduled maintenance on the 2018 Jeep Grand Cherokee?

At 20,000 miles or 2 years: inspect front suspension, tie rod ends, and replace if necessary; inspect the front and rear axle fluid, change if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing; inspect the brake linings, parking brake function; replace the air conditioning filter. Oil changes in between follow the oil-change indicator.

Where can I find the 2018 Jeep Grand Cherokee owner's manual?
