Jeep Grand Cherokee 2011–2021 · Maintenance schedule & cost to maintain

The 2012 SRT8, 2017 and 2018 SRT books and the SRT section of the 2020 book cap it at 6,000 mi or 6 months, whichever comes first, whatever the indicator shows. Full synthetic 0W-40 (MS-12633 in the 2017, 2018 and 2020 SRT books): 7 qt on the 6.4L, 8.3 qt on the 6.2L. No SRT book was found for 2013-2016, 2019 or 2021.

Jeep ties rotation to every oil change (every 8,000 mi on the 2011-2012 list, every indicator alert in the 2013-2021 books), and says rotate at the first sign of irregular wear even if that comes sooner. Rotation keeps the four tires wearing alike, which the 4WD system needs: Jeep says a mismatch will damage the transfer case (see the tires item). RepairPal 2011-2021: $49-$72.

Inspect every 20,000 mi (2013-2021 charts; every 24,000 mi on the 2011-2012 lists and the SRT charts). Change it at that visit if the Jeep is used for police, taxi, fleet, off-road or frequent trailer towing; the SRT charts add sustained high-speed driving. Jeep prints no change mileage for anyone else. A rear axle with the electronic limited-slip needs 75W-85 with friction modifier. RepairPal per axle: $121-$197.

Replace the fuel filters and drain water every 30,000 mi on diesel up to B5, and every 20,000 mi on B6-B20 biodiesel, in the 2014 and 2015 supplements. Both books also replace the diesel's engine air filter every 30,000 mi and its cabin filter every 10,000 mi. The filter must meet a 3-micron rating. No RepairPal fuel-filter price was read, so none is given.

The SRT books drain and refill the transfer case every 30,000 mi (2012 SRT8 list, 2017 and 2018 SRT charts, 2020 SRT chart), four times as often as the non-SRT 120,000 mi. No condition is attached, so it is not a severe-only item. No RepairPal transfer-case fluid price was read, so none is given.

Severe: change fluid and filter at 60,000 mi (2013 chart) or 64,000 mi (2011-2012 lists) if the Jeep is used for police, taxi, fleet or frequent trailer towing; the 2013 book adds off-road. Everyone else changes it at 120,000 mi. Use ATF+4 only. This item ends in 2013: the 2014-2021 eight-speed has no change interval (see that item). RepairPal 2011-2013: $186-$220.

6.4L: 96,000 mi in the 2012 SRT8 list, the 2017 and 2018 SRT charts and the 2020 SRT chart. Trackhawk 6.2L: 60,000 and 120,000 mi in the 2018 SRT and 2020 SRT charts. Mileage only. The 2012 SRT8 book names LZTR6AP11EG gapped 0.043 in.

Inspect and replace if necessary at 100,000 mi in the 2013-2019 charts; the 2020 and 2021 charts say replace it. 96,000 mi on the 2011-2012 lists, where the 2011 book marks it as recommended but not needed for the emissions warranty. The SRT charts put it at 90,000 mi. RepairPal 2011-2021: $97-$198.

The 2011 and 2012 lists flush and replace the coolant at 60 months or 104,000 mi, whichever comes first, with the 5-year/100,000-mile formula. The 2012 SRT8 list says 60 months or 102,000 mi. In the 2013-2021 books the coolant is the 10-year/150,000-mile formula (see the 150,000 mi bucket). RepairPal 2011-2012: $284-$358.

The 2014 and 2015 diesel supplements replace the accessory drive belt(s) at 100,000 mi. The gas charts differ by book (see the 150,000 mi bucket). RepairPal 2011-2021: $84-$103, rows not split by engine.

The 2013-2021 charts inspect it at 30,000, 60,000, 90,000 and 150,000 mi and change it at 120,000 mi, with no severe line. The 2011-2012 lists inspect at 32,000 and 96,000 mi, change at 128,000 mi, and at 64,000 mi for police, taxi, fleet or frequent trailer towing. Single-speed Quadra-Trac I takes ATF 3353, two-speed Quadra-Trac II takes ATF+4. The 2014-2015 diesel supplements also change it at 120,000 mi.

Flush and replace at 10 years or 150,000 mi, whichever comes first, in the 2013-2021 charts and the 2014-2015 diesel supplements; the 2017, 2018 and 2020 SRT charts say 120 months if not done at 150,000 mi. No severe number is printed. A 2011 or 2012 car runs on the shorter 5-year clock (100,000 mi bucket). RepairPal 2013-2021: $455-$588.

Only some books print it. The 2011 list replaces the belt(s) at 120,000 mi; the 2012-2019 charts carry no belt row; the 2020 and 2021 charts replace it at 150,000 mi and inspect the tensioner and pulley then. The SRT charts inspect the belts at 60,000 and 120,000 mi. On a book with no row, replace it on condition: cracks, glazing or squeal. RepairPal 2011-2021: $84-$103.

Every 2014-2021 book says the factory fluid lasts the life of the vehicle and routine fluid and filter changes are not required, unless the fluid is contaminated (with water, say) or the transmission is taken apart. No book prints a severe interval, towing included. The dipstick is gone; a dealer checks the level with special tools. Every 2014-2021 fluid table specifies Mopar ZF 8&9 Speed ATF or equivalent.

No gas or diesel book from 2011 to 2021 schedules a brake fluid change. The only printed number is in the 2020 book's SRT fluid table: if DOT 4 is used instead of DOT 3, change it every 24 months. The books say to check the level when pads are replaced. Test the fluid at every brake job. RepairPal brake bleed 2011-2021: $85-$125.

No Jeep interval; the generic wear range is 50,000-100,000 mi. Worn dampers cup the tires on their own, so new tires on worn struts wear out early whatever the alignment says, and new struts need an alignment after. Air-sprung cars add the Quadra-Lift failures in this file's problems list; the 2015 diesel supplement alone asks to clean the rear air springs at every oil change. RepairPal rows here swing from $1,079 to $5,394 by year, so no cost is given.

Jeep inspects the CV joints every 24,000 mi (2011-2012), every 30,000 mi (2013-2019 charts) and at every oil change in the 2020-2021 books. A torn boot flings grease onto the brakes and lets grit into the joint, so a boot caught early is cheaper than the axle it protects. No RepairPal axle price was read, so none is given.

No Jeep interval; Jeep inspects the front suspension and tie rod ends every 20,000 mi (2013-2021 charts). Generic life is 70,000-120,000 mi, less on rough roads, and 8-10 years regardless of miles. Worn bushings let the alignment wander right after it is set, so check them before paying for one. RepairPal control arm rows run $227-$1,337 by year, so budget from a quote.

Not a Jeep mileage item. Align after new tires, struts, control arms or tie rods, and check it about once a year; skipping it after suspension work wastes the tires you just bought. RepairPal 2011-2021: $159-$233.

Jeep says four-wheel drive depends on tires of equal size, type and circumference on each wheel, and a difference will damage the transfer case. So a single replacement on a 4WD car has to match the other three, and rotation on schedule keeps them matched. Fit the tire to the use: an all-terrain on a highway Laredo gives up wet grip and tread life for nothing.

No Jeep interval and no WK2-specific mount weakness verified here. Rubber and hydraulic mounts wear with age and torque, typically 80,000-150,000 mi, sooner on the V8s and in stop-and-go use. A collapsed mount lets the engine move, which loads the other mounts, the exhaust joints and the hoses. Symptoms: a clunk into drive or reverse, vibration at idle in gear. RepairPal 2011-2021: $418-$788.
