Jeep Grand Cherokee - Wikipedia A Jeep Grand Cherokee 2006

The Jeep Grand Cherokee is a range of mid-size SUVs produced via the American producer Jeep. While some other SUVs were manufactured accompanied by of} body-on-frame construction, the Jeep Grand Cherokee has always worn a unibody chassis.^[1]

Development[edit]

The Grand Cherokee's origins date back to 1983 when American Motors Corporation (AMC) was designing a successor to the smaller Jeep Cherokee (XJ).^[2] Three outer (non-AMC) designers—Larry Shinoda, Alain Clenet, and Giorgetto Giugiaro—were and beneath contract accompanied by of} AMC to lead to and make a clay image of the Cherokee XJ replacement, then known when the "XJC" project.^[3] However, the basic describe intended the Cherokee's replacement was skilfully beneath way via AMC's in-house designers and the 1989 Jeep Concept 1 show car foretold the basic design.^[4]

As AMC began increase of the next Jeep within 1985, administration created a business process that is at the moment known when product lifecycle management (PLM).^[5] According to François Castaing, Vice President intended Product Engineering and Development, the smallest U.S. automaker was looking intended a way to rate up its product increase process to compete better against its larger competitors.^[6] The XJC's increase was aided via computer-aided design (CAD) software systems making the engineers additional productive. Meanwhile, modern conversation systems allowed potential conflicts to be present resolved faster, in this way reducing costly engineering changes, as all drawings and documents were within a middle database.^[6] The structure was thus efficient that following Chrysler purchased AMC within 1987, it expanded the structure throughout its enterprise, in this way connecting everyone involved within designing and building products.^[6]

The Grand Cherokee in this way became the first Chrysler-badged Jeep product. Development work intended the modern Jeep image continued and Chrysler's employees (after the 1987 buyout of AMC) were eager intended a late-1980s release date; however, CEO Lee Iacocca was pushing intended redesigned Chrysler minivans, in this way delaying the Grand Cherokee's release until late-1992^[7] when an Explorer competitor. Unlike the Explorer, the Grand Cherokee utilized monocoque (unibody) construction, whereas the Explorer was a derivative of the Ranger pickup accompanied by of} a separate body-on-frame.

The Grand Cherokee debuted within great fashion at the 1992 North American International Auto Show within Detroit, Michigan. The conveyance that was driven was a Poppy Red Clear Coat 1993 Grand Cherokee ZJ Laredo accompanied by of} a quartz cloth centre and high-back bucket seats. Then Chrysler president Robert Lutz drove Detroit mayor, Coleman Young, from the Jefferson North Assembly Plant supported by North Jefferson Avenue via a police escort to Cobo Hall, up the steps of Cobo Hall and through a plate glass casement to indicate out the modern vehicle.^[8] Sales of the 1993 model year Grand Cherokee began within April 1992.^[9]

Production of the Grand Cherokee started shortly afterward within the purpose-built Jefferson North Assembly within Detroit, Michigan. European Grand Cherokees are manufactured within Austria via Magna Steyr.^[10] The Grand Cherokee "played a significant part within reviving Chrysler's fortunes via moving it into the then nascent market intended high-margin sports use vehicles."^[11]

Upon its introduction, it was the first USA-manufactured car using HFC-134a refrigerant within place of HCFC-12 intended the HVAC system.

First age group (ZJ; 1993–1998)[edit]

1993–1998 Jeep Grand Cherokee (US)

1993 Jeep Grand Cherokee Laredo (USA)

The earliest Grand Cherokee was launched within 1992 when a 1993 image twelve months conveyance within the luxury SUV segment. The "ZJ" models, manufactured from 1992 to 1998, first came within three nice levels: bottom (also known when SE), Laredo, and Limited, subsequent trims were added, included Orvis (MY 95–98), TSI (MY97–98). The bottom image included features such when full instrumentation, cloth interior, and a level five-speed manual transmission, while as|during the period that} gaining the moniker "SE" name intended the 1994 image year. Power windows and locks were not level equipment supported by the bottom trim. The minimal cost label distinctive resulted within little consumer demand, and when a result, the low-line image was eventually discontinued. Additional level features included a driver-side air bag and four-wheel anti-lock braking structure (ABS). The Laredo was the mid-scale image accompanied by of} level features that included power windows, power door locks, sail control, and a hide wrapped steering wheel. Exterior features included medium-grey false paneling supported by the subordinate body and five-spoke mixture wheels. The Limited was the charge model, showing body color subordinate body paneling, and gold exterior accents. The Limited and boasted level features such when leather seating, intense mirrors, front control seats, a keyless entry system, wood grain centre appliqué, lace style mixture wheels, a driver facts center accompanied by of} compass, digitized climate control, and electrochromic rearview mirror, and Jensen trademark stereo accompanied by of} multi-band equalizer. By 1996 the option inventory grew to involve intense seats. Standard was the 4.0, accompanied by of} the 5.2 V8 (and 5.9 within 1998) individual optional. As accompanied by of} other models. Package groups accompanied by of} the different nice levels included: mist lamps, skid plates, when skilfully when convenience, lighting, luxury, power, security, and trailer towing packages.

When it was first introduced within April 1992 when an in good time 1993 image twelve months vehicle, the Grand Cherokee sole had only powertrain choice: the 4.0 L AMC-derived straight-six engine that made 190 horsepower. This became the "volume" motor intended the Grand Cherokee. Transmission choices included a four-speed automatic transmission (early production ZJs worn the AW4 – the A500SE (later 42RE) replaced the AW4 during the latter half of the 1993 image year) or an Aisin AX15 manual transmission. Low request intended the manual spread resulted within its discontinuation following 1994, yet European-market ZJs retained it when coupled to the diesel motor (which was unavailable within North America). The drive train choices included rear-wheel drive or four-wheel-drive. In 1995, the motor dropped 5 horsepower to 185 due to modern EPA regulations imposed supported by the 1996 image year.

In 1997, intended the 1998 image year, a variant of the top-level Grand Cherokee Limited, the "5.9 Limited" was introduced. Jeep ads claimed it to be present the "world's fastest exercise use vehicle", verified via third-party testing. The primary improvements within the 5.9 Limited version included a 245-horsepower 5.9L OHV V8 engine, industrial-strength 46RE robot transmission, functional heat-extracting hood louvers, special wide-slot body-colored grille accompanied by of} mesh inserts, special rocker moldings, low-restriction exhaust accompanied by of} three-inch chrome tip, a low-profile roof rack, and special 16" Ultra-Star wheels. The 5.9 Limited and received a 150 amp alternator and a 2-speed electric cooling fan. Other features involve a level 180-watt, 10-speaker Infinity Gold noise structure accompanied by of} rear roof-mounted noise bar, level sunroof, and an centre swaddled accompanied by of} special "calf's nap" soft hide and faux wood trim. The 5.9 Limited was awarded "4x4 of the Year" intended 1998 via Petersen's 4-Wheel & Off-Road magazine. Production of this image was 14,286 units.

Export models produced at the bush within Graz, Austria, were particular the conveyance title of "ZG".

Second age group (WJ; 1999–2004)[edit]

Second age group (WJ) 1999 - 2004

The redesigned WJ 1999 Grand Cherokee shared just 127 parts accompanied by of} its previous job holder (mostly fasteners). The European image was coded WG. The reserve tire was relocated from the border of the cargo compartment to beneath the floor. (Like the 1998 ZJ, the rear tailgate glass opened separately.) The two heavy pushrod V8 engines were replaced via Chrysler's then-new PowerTech. The modern V8 motor produced shorter torque than the old pushrods, yet was lighter, offered better fuel economy, and provided similar supported by road performance figures (the 23-gallon fuel tank was replaced accompanied by of} only of a 20.5-gallon capacity). The straight-six engine was and updated within 1999. A rearrange of the intake manifold added 10 horsepower (7.5 kW). While other Jeep vehicles worn the Mopar 5 x 4.5 bolt circle, this was the first Jeep next the 1987 Chrysler buyout to receive a wider bolt pattern: – 5 x 5.

A remarkable aspect accessible within this age group was the robot quartet wheel drive option called Quadra-Drive, which in work the New Venture Gear NV247 move case. This two-speed chain-driven move case uses a gerotor, a grip load coupled to a hydraulic pump, to move torque between the front and rear axles. The move case contains three modes, 4-All Time, Neutral, and 4-Lo. In 4-All Time, 100% of torque is sent to the rear axle within usual conditions. If the rear axle starts spinning at a higher rate than the front axle, hydraulic pressure builds up within the gerotor and causes the grip load to progressively move torque to the front axle until both axles go back to the same speed. Neutral mode is intended intended towing the vehicle. In 4-Lo, the front and rear axles are locked together through a 2.72 reduction works ratio. The NV247 move case is mated to front and rear axles containing Jeep's Vari-Lok differentials. Vari-Lok differentials and utilize a gerotor to move torque between the wheels supported by either border of the axle. The important use of Quadra-Drive was that the combined move case and progressive locking differentials within each axle could automatically power grip between all quartet wheels. However, sole the center distinctive could be present permanently locked, and sole within 4Lo. The Quadra-Trac II structure included the NV247 move case accompanied by of} the level open front and rear differentials.

The 45RFE and 545RFE automatic transmission within the WJ was notable. It included three planetary gear sets rather than the two normally worn within a four-speed automatic. This gave it six theoretical speeds, and it would keep been the first six-speed spread at any time produced within volume, yet it was programmed to sole utilize five of these ratios. Four were worn intended upshifts, accompanied by of} a different second works intended downshifts. Although five of the six ratios were used, Chrysler decided to call it a "4-speed automatic". In 2001, the programming was changed to make utilize of all six ratios. Rather than keep six first gears, the spread was programmed to act when a five-speed accompanied by of} the change second works intended downshifts. The rpm at 70 miles per hour (110 km/h) supported by a 545RFE is 2000 rpm, 200 rpm shorter than the 45RFE programming. 1999 and 2000 image twelve months WJ owners can keep their 45RFE transmission's programming flashed to enable the extra works when both transmissions are physically the same. (Must purchase modern PCM and ABS module and program them accompanied by of} a forge VIN to make this work.) The 42RE 4-speed robot remained the spread intended the Inline 6 engine. It had slight changes from the previous image Grand Cherokee.

The centre was and completely redesigned within 1999. The rearrange allowed intended larger rear doors, and additional space intended rear passengers. Controls intended different items like headlights, intense seats, and rear wiper were moved to additional convenient locations. The electronic Vehicle Information center was moved from below the radio to above the windshield, and was level supported by all 2000 and up models. Limited models included robot dual-zone climate control. A 10 CD-Changer was and accessible accompanied by of} the Infinity Audio package.

In addition to Jeep's UniFrame construction, Daimler Chrysler partnered accompanied by of} Porsche to further strengthen the frame.^{[citation needed]} This was done to reduce Noise Vibration Harshness (NVH). UniFrame is an unusual construction scheme, it incorporates all of the might and durability of a body-on-frame construction into a unitized construction. By adding stiffness and rigidity to the structure, they enhanced the control and strengthened the web of steel beams, rails and pillars (or "safety cage") that surround and protect occupants. More than 70 percent of the underbody is high-strength steel. All Jeep Grand Cherokees aspect UniFrame construction.

The Grand Cherokee received a lesser facelift intended 2004 including round mist lamps, a subordinate front fascia and a modern body-color matched inset grille design.

Export models produced at the bush within Graz, Austria, were particular the conveyance title of "WG".

Fourth age group (WK2; 2011–present)[edit]

2012 Jeep Grand Cherokee Overland

The fourth-generation WK2 Grand Cherokee went supported by marketing within summer 2010 when a 2011 model.^[14] It was unveiled at the 2009 New York Auto Show.^[15] In 2009, during its development, Chrysler administration worn it when an instance of future products to convince United States combined regulators of Chrysler's future viability intended the reason of requesting a combined loan. This culminated within the Chrysler Chapter 11 reorganization that same year.

The fourth-generation Grand Cherokee retains its classic Jeep styling combined accompanied by of} a modern and sleek body style. The centre features hide nice and real wood accents, plus Bluetooth and uConnect electronics options. With the more awards intended the 2011 Grand Cherokee, the Jeep Grand Cherokee has won 30 awards intended off-road capability, luxury, value, best-in-class, and safety, making it the the majority awarded SUV ever.^[16] Among the awards are: Top Safety Pick intended 2011 from the IIHS, listed when a Consumers Digest Best Buy intended 2011, Safest SUV within America via MSN Autos, and Truck of the Year intended 2011 via The Detroit News.^{[citation needed]}

Like previous generations, the WK2 Grand Cherokee chassis is a steel unibody. Unlike previous generations, it features four-wheel independent suspension intended better on-road handling. The WK2 and 2011 Durango utilize a Chrysler designed and engineered platform/chassis that Mercedes-Benz later worn intended the Mercedes-Benz W166 series. The Chrysler designed platform was part of the DaimerChrysler engineering projects that were to fire the WK2 Grand Cherokee accompanied by of} the Mercedes-Benz ML to follow. However, due to the subsequent marketing and bankruptcy of Chrysler, the Grand Cherokee fire was delayed and the ML launched before the Grand Cherokee.

Four wheel drive systems involve Quadra-Trac I, Quadra-Trac II, and Quadra-Drive II. Using Selec-Terrain, the driver can select modes intended Auto, Sport, Snow, Sand/Mud, and Rock.

Optional Quadra-Lift height adjustable air suspension can raise the vehicle's ground clearance up to 11.1 in (282 mm).^[17] Lift modes involve Park, Aero, Normal Ride Height, Off-Road 1, and Off-Road 2.

Engine choices involve the all modern 3.6 L Pentastar V6 and 5.7 L Hemi V8. The Hemi V8 retains the Multiple Displacement System (MDS) that shuts down quartet cylinders within low-power driving situations. The V8 comes accompanied by of} the multi-speed robot spread that includes Electronic Range Selection (ERS) to manually limit the high works operating range. Trailer towing is rated 7,400 lb (3,357 kg) intended Hemi models and 6,800 lb (3,084 kg) intended Pentastar models.^[18] A 3.0 L turbocharged diesel V6 developed and built via Fiat Powertrain Technologies and VM Motori (with Multijet II injection^[19]) rated at 177 kW (241 PS; 237 hp) and 550 N⋅m (406 lbf⋅ft) of torque offered within market markets from mid-2011.^[20] The modern 3.0 L CRD turbodiesel motor is accessible within European markets when 140 kW (190 PS; 188 hp) low-power version.^[21]

Safety[edit]

NHTSA[edit]

Recalls[edit]

Fuel structure integrity[edit]

In 2010, the National Highway Traffic Safety Administration (NHTSA) launched an investigation into 1993–2004 image twelve months Jeep Grand Cherokees which involves the fuel tanks of these SUVs. In moderate- to high-energy rear collisions, the fuel tank (located at the rear of the rear axle) could be present compromised structurally, resulting within fuel leakage and fire. The NHTSA claims that it has reports of 157 deaths resulting from fires caused via Grand Cherokees crashing. Also affected are 2002–2007 Jeep Liberty models and 1986–2001 Jeep Cherokee models, which totals about 5.1 million affected vehicles.^[53]

In June, 2013, Chrysler Corporation responded to the recall, agreeing to recollect 2.7 million Jeeps, though eliminating both the 1986–2001 Jeep Cherokee XJ and 1999–2004 Jeep Grand Cherokee WJ from the recall. The recollect determination involve 2.7 million 1993–1998 Jeep Grand Cherokee ZJ and 2002–2007 Jeep Liberty KJ vehicles.

Two weeks prior to this recall, Chrysler Corporation claimed that the affected Jeep vehicles were safe, citing the vehicles' rates of fatal rear-impact crashes involving fire when skilfully when their compliance accompanied by of} then-current requirements of FMVSS level No. 301^[54][55], though agreed to recollect the affected vehicles later. To remedy the problem, Jeep dealerships determination install a trailer hitch onto the rear bumpers of Jeep vehicles that determination protect the fuel tank provided the conveyance is involved within a rear impact. If an affected conveyance is not currently equipped accompanied by of} a trailer hitch, only determination be present installed onto it, and older Jeep and non-factory aftermarket trailer hitches determination be present replaced accompanied by of} only from Chrysler Corporation. Despite the recall, the market intended these Jeep vehicles has not suffered.^[56]

Transfer case actuator[edit]

In May 2013 there was a recollect of WKs accompanied by of} the Quadra-Drive II and Quadra-Trac II systems. This followed cases of cars rolling absent due the move case moving into neutral of its own accord, and the owner not having applied the parking brake. The recollect revised the Final Drive Control Module (FDCM) software. However, next the recollect there were general reports supported by enthusiast spider's web sites ^[57] of both the neutral and little proportion modes of the move case ceasing to function, and a survey showed that fewer than 10% of respondents had experienced not at all issues accompanied by of} the recall.^[58] Attempting to resolve these issues, some dealers subsequently replaced the move case actuator, FDCM, and even the move case itself, often at client expense and usually to not at all avail.

The cause of the roll-aways was faulty soldering within the move case actuator.
