The fourth-generation Jeep Grand Cherokee (WK2) is a mid-size SUV produced by the American marque Jeep from mid-2010 to 2022. It was introduced in 2010 for the 2011 model year by Jeep.[6] The unveiling took place at the 2009 New York Auto Show, where it received 30 awards.[7][8]

The new body design represented a 146 percent increase in torsional rigidity compared to the previous design, which helped to improve durability and reduce noise, vibration, and harshness.[9]
Like the previous generations, the chassis is steel unibody. Unlike previous models, the new WK2 features a four-wheel independent suspension for better on-road handling. The Grand Cherokee (with the 2011 Durango) WK2 platform uses a derivative related to Mercedes-Benz's W166 series.
Four-wheel drive systems include Quadra-Trac I, Quadra-Trac II, and Quadra-Drive II. Using Selec-Terrain, the driver can select modes for Auto, Sport, Snow, Sand/Mud, and Rock.
Optional height-adjustable air suspension, which Jeep refers to as "Quadra-Lift", can raise the vehicle's ground clearance up to 11.1 in (282 mm).[10]
Engine choices included the 3.6L Pentastar V6 or the 5.7L Hemi V8. The Hemi V8 retained the Multiple Displacement System (MDS) that shuts down four cylinders in low-power driving situations, and the V8 remains coupled with the multi-speed automatic transmission which includes Electronic Range Selection (ERS) to manually limit the high gear operating range. Trailer tow is rated 7,400 lb (3,400 kg) for Hemi models and 5,000 lb (2,300 kg) for Pentastar models.[11]
The 3.6L Pentastar V6 replaced the 3.7L and 4.7L PowerTech engines. The 5.7L Hemi engine was retained as the V8 option, although no Hemi badging is used on the exterior of the vehicle. Also, the WK program code remained unchanged.
A 3.0L turbocharged diesel V6 developed and built by Fiat Powertrain Technologies and VM Motor (with Multijet II injection[12]) rated at 177 kW (241 PS; 237 hp) and 550 N⋅m (406 lbf⋅ft) of torque is offered in export markets by mid-2011. [needs update][13] On January 14, 2013, at the Detroit Auto Show, Jeep announced that this new EcoDiesel engine will become available in the 2014 Grand Cherokee,[14] together with the new 8HP70 8-speed automatic transmission.[15] The new 3.0L CRD turbodiesel engine is offered in European markets in a 140 kW (190 PS; 188 hp) low-power version.[16]
The SRT Hellcat supercharged V8 was made available for the Grand Cherokee Trackhawk. With 707 hp (527 kW), it was the most powerful SUV produced by Chrysler as of 2021.
In 2012, Swedish automotive magazine Teknikens Värld revealed that the Jeep Grand Cherokee failed one of their avoidance maneuver tests known as the "Moose test". Other SUV models in its class had no issues passing the test.[21] German magazine Auto, Motor und Sport (AMS) later tested the same press vehicle in a slightly different avoidance maneuver test that meets ISO (International Organization for Standardization) standards. Unlike the results of the Swedish test, the Jeep remained on all four wheels and did not lose any tires to a blowout.[22] Teknikens Värld tested the updated 2014 Jeep Grand Cherokee and found that it passed the test; even up to a speed of 44.1 mph (71 km/h).[23]

In 2016, approximately 1.1 million 2014–2015 Jeep Grand Cherokees were recalled for rollaway risks because the design of the shifter made it difficult for drivers to determine whether or not the vehicle is still in gear. This design was discontinued in 2016 in favor of a more traditional design.
The issue was linked to 41 injuries, 212 crashes, and 308 reports of property damage[24] and shortly after the recall was announced, actor Anton Yelchin was killed by his Grand Cherokee rolling backward into him after he exited it while it was still in gear.[24] After Yelchin's death, the Chrysler accelerated the recall campaign and took steps to get the affected Jeeps repaired faster than originally planned.[25] Yelchin's family filed a wrongful death lawsuit against FCA that was settled out of court in 2018.[26]
On April 20, 2011, Jeep announced that the SRT8 version would be debuted at the 2011 New York Auto Show. It can accelerate from 0–60 mph in 4.7 seconds and can do the quarter-mile in 13.4 seconds.[27] Auto reviews measured this at 4.5 seconds, making the 2014 SRT the fastest Jeep ever produced at the time.[28] The 2013-14 SRT Jeep Grand Cherokee includes a 6.4L Hemi motor producing 470 hp (350 kW) and 465 lb⋅ft (630 N⋅m), which was the most powerful engine ever included in a Jeep at the time of production.
The Grand Cherokee SRT8 debuted alongside two other vehicles manufactured by Chrysler Corporation: the Chrysler 300 SRT8 and Dodge Charger SRT8, both of which also took a one-year hiatus while the new models debuted.
The new Grand Cherokee SRT8, which started production on July 16, 2011,[29] is equipped with a 470 hp (350 kW; 477 PS) 6.4 L Hemi V8 engine. Jeep claims the new SRT8 gets 13 percent better fuel economy than its predecessor.[citation needed] To improve gas mileage,[clarification needed] Jeep has employed a new active exhaust system that lets Chrysler's cylinder-deactivation Fuel Saver Technology operate over a wider rpm band. Chrysler claims that with the larger gas tank, the SUV can now travel up to 500 miles (800 km) on a single tank, while other sources estimate the range to be 450 miles (720 km).
For the 2012 model year, V8 models were updated to use the 65RFE 6-speed automatic transmission.[30]
For the 2013 model year, Jeep introduced the Trailhawk off-road oriented trim. For the Overland Summit trim, Front Park Assist, power-folding side mirrors, and headlight washers became standard equipment and Nappa leather seats became available in black or saddle-colored.[31]
Jeep also introduced "Alpine" and "Vapor" special edition models of the Grand Cherokee SRT8. Production of each model for the U.S. market was limited to 400 units. The "Alpine" model was painted in Bright White and the "Vapor" model was painted in Brilliant Black. Features of both models include the standard 20-inch wheels in a Black Vapor Chrome finish and a glossy black color for exterior badges, front grille trim, rear light bar, and bumper step pad.[32]

On January 14, 2013, Jeep unveiled a revised WK2 Grand Cherokee at the North American International Auto Show at Cobo Center, along with a revised 2014 Jeep Compass and Jeep Patriot. The new Grand Cherokee offered a 3.0L DOHC V6 diesel engine that gets up to 30 MPG, a 3.6L Pentastar V6 engine that gets up to 24 MPG and has 290 hp (216 kW), a 5.7L Hemi V8 engine that gets up to 21 MPG and has 360 hp (268 kW), and the 6.4L Hemi engine produces 470 hp (350 kW) (SRT only). The models are the Laredo, the Limited, the Overland, and the Overland Summit Edition model has been renamed Summit. A new front end with a revised body-colored grille, new, smaller headlamps, and new tail lamps round out the exterior changes. The silver bezel on the back was removed. The opening rear tailgate window of previous models has been replaced with fixed glass. There are also new seventeen, eighteen, and twenty-inch wheel and tire choices. The SRT8 model will continue to be offered but as an "SRT" and not an "SRT8" badged model, and for the first time will offer details like blacked-out head and tail lamps. Inside, the Summit model receives the SRT's nineteen-speaker Harman/Kardon surround sound system, all Grand Cherokees receive a new steering wheel with paddle shifters standard in every model, an eight-speed TorqueFlite 8 automatic transmission, and an 8.4-inch touch screen display with Garmin navigation software, an optional CD player, and the U Connect Access System first introduced in 2013 Ram 1500. A U Connect 5.0 touch-screen radio will also be available with an optional CD player. The Selec-Terrain System receives multiple upgrades on four-wheel-drive Grand Cherokees. New exterior colors, interior fabrics and materials, and interior colors become available.
For 2014, "SRT8" was no longer a model of Jeep, but a separate corporate entity. The "8" designation was dropped in the "SRT" line for this year, the Grand Cherokee being referred to as a "SRT Jeep Grand Cherokee." The SRT model received many features. For example, in the interior, it received a steering wheel with the SRT insignia, twenty-inch alloy wheels, "performance" tires, and additional SRT-only details, including:

The 2015 Limited Edition model no longer has dual exhausts. This feature only comes in the Overland and up editions. There are no other major changes for the 2015 model year. However, the Limited, Summit, and Overland trims will include HD Radio as part of the U Connect feature. The SRT receives a modest 5 hp (4 kW) bump, in part due to a reflash of the PCM.
At the 2016 New York International Auto Show, Jeep announced new updates for its Grand Cherokee mid-size SUV, which included two new trim levels:[33]
The Trailhawk trim level is the "off-road" oriented trim level, which made its initial appearance in 2013, returned for 2017. It includes a Quadra-Drive II four-wheel-drive system along with a Quadra-Lift air suspension system, the Selec-Speed control, and Hill Descent Control. It will offer the same seven-slot front grille that was first offered on the 2016 Grand Cherokee Laredo and Limited 75th Anniversary Edition models, red-painted front-mounted tow hooks, standard eighteen-inch and optional twenty-inch alloy wheels, special off-road tires with Kevlar belts, Neutral Gray-painted exterior accents and badges, optional Mopar side rock rails, a standard U Connect 8.4-inch touch-screen infotainment system, red accent stitching throughout the interior, a 'Trailhawk' emblem on the steering wheel, brushed Piano black interior trim panels, and gunmetal finished interior components.
The Summit trim level is the "upscale" version of the Grand Cherokee, which was revamped in 2014, and was revamped again for 2017. It offers a restyled front grille with LED front fog lamps and twenty-inch polished alloy wheels. Its features include cross-stitched leather-trimmed interior, Active Noise Cancellation, an acoustic windshield and front side glass, leather-trimmed dashboard and door panel inserts, a nineteen-speaker, 825-watt Harman Kardon surround-sound system, automatically folding power side-view mirrors, a suede-trimmed headliner, a blind-spot monitoring system, lane departure warning, parallel and perpendicular park assist systems, Berber carpeting, and other interior appointments.
New exterior paint color options include Rhino, Diamond Black Crystal Pearl Coat, Light Brown Stone, True Blue, and Ivory Pearl Coat (availability varies by trim level).
All 2017 models received a second facelift that features new alloy wheel designs, reshaped headlights, and a reshaped grille. The new grille and headlights come from the 75th Anniversary Edition models of 2016, however, without the bronze-painted accents. In addition, all models receive a new 'GRAND CHEROKEE' emblem for the front doors.
The 75th Anniversary Edition models, based on the base Laredo and mid-level Limited, also continue on for 2017.
The SRT trim for 2017 got a new front fascia and a new interior.
Changes to the 2018 Jeep Grand Cherokee lineup (aside from the SRT Trackhawk model) include:[34]
The "base" U Connect 7.0 Infotainment System includes:
The "upgraded" U Connect 8.4 Infotainment System with GPS Navigation includes all of the existing features of the U Connect 7.0 Infotainment System, but also adds the following features:
Both radios include the option to add a single-disc, center console-mounted CD/MP3 player, and some trim levels equipped with the 8.4-inch radio can also be equipped with a rear-seat DVD and Blu-ray entertainment systems with dual screens, HDMI input, and independent CD/MP3/DVD/Blu-ray players, with two pairs of wireless headphones also included in the package. On Limited, Trailhawk, and Sterling Edition models, the Luxury Group is required to have the rear-seat entertainment system option. The option can be selected independently on all other trim levels.
A six-speaker, non-amplified audio system is standard on Laredo, Laredo "E", Altitude, and Limited models. A nine-speaker, 506-watt Alpine amplified surround-sound audio system is included on Trailhawk, Sterling Edition, Overland, High Altitude, SRT, and SRT Trackhawk models, and is optional on Altitude, Limited, and Summit models. An eighteen-speaker, 825-watt Harman Kardon amplified surround-sound audio system comes standard on the Summit model, and is optional on Overland, SRT, and SRT Trackhawk models.
Jeep introduced the 2018 Jeep Grand Cherokee SRT Trackhawk at the 2017 New York International Auto Show. The SRT Trackhawk is the highest-performance Grand Cherokee model to date.[35]
Largely unchanged from 2018, the 2019 model year Grand Cherokee received only a few minor changes. The 25th Anniversary Sterling Edition model is now discontinued, though its aluminum-alloy wheel design is now standard on the Overland trim, and optional on the midlevel Limited trim. Laredo, Laredo E, Upland (now available with two-wheel-drive), Altitude, Limited, Trailhawk, Overland, High Altitude, Summit, SRT 392, and SRT Trackhawk models continue for 2019.[36] The 8.4 touchscreen is updated to a high-definition "Dissociated" display for the 2019 model year.
A new Limited X Package adds SRT-inspired styling cues to the mid-level Limited trim. The Overland and Summit trims gain new aluminum-alloy wheel designs.
The mid-level Limited trim receives a standard U Connect 4C 8.4 infotainment system with Garmin GPS navigation, which was previously available as an extra-cost option, leaving only the base Laredo, Laredo E, and Upland trims with the base U Connect 4 7.0 infotainment system as standard equipment. In addition, the U Connect 4C 8.4 infotainment system with Garmin GPS navigation receives a new 8.4-inch, high-definition "Dissociated" touchscreen display, which was first introduced on the 2017 Chrysler Pacifica minivan.
Blind Spot Detection System (BLIS) and Forward Collision Warning System (FCWS), previously extra-cost options available as part of a package on top-level trims of the Grand Cherokee, are now standard equipment on all Grand Cherokee trim levels.
Three new exterior colors, Green Metallic, Sting Gray, and Slate Blue were offered for 2019. A new interior color scheme, Black and Bridle Brown was also added for the Summit trim level, and both Trailhawk and Overland trims receive new Piano Black interior trim accents.
Trim levels that continue for 2019 are Laredo, Laredo E, Upland, Altitude, Limited, Trailhawk, Overland, High Altitude, Summit, SRT, and SRT Trackhawk, with Limited X being new for 2019.
For 2022, Jeep marketed the outgoing Grand Cherokee WK2 alongside the all-new Grand Cherokee WL model as the "Grand Cherokee WK" (not to be confused with the Grand Cherokee (WK), which was produced from 2005 until 2010). The lineup is condensed to base Laredo "E", mid-level Laredo "X", and range-topping Limited trims, with only the 3.6 L Pentastar V6 gasoline engine. However, in addition to the Stellantis-produced (but ZF derived) 850RE 8-speed automatic transmission, the ZF-produced 8HP75 8-speed automatic transmission, built in Germany and previously only available with the 5.7L HEMI V8 gasoline engine, will also be offered as at no additional cost on all models.[37]
In 2009, the company announced a US$1.8 billion, 285,000-square-foot (26,477 m2) expansion of its Jefferson North Assembly plant in Detroit to allow flexible manufacture of the next-generation model, as well as the 2011+ Dodge Durango off the same platform that was developed jointly with Mercedes (ML Chassis).[38]
