Jeep Grand Cherokee 3 / WK

“The Grand Cherokee Jeep is a benchmark for comfort, off-road and the most important thing for customers – dynamics,” – these are the words the marketing director commented on the debut of the next model of the famous American SUV. Have the promises been kept? Combining comfort and off-road capabilities proved to be a rather difficult task – a car with advanced technical solutions turned out to be expensive and difficult to operate. The Jeep Grand Cherokee is a great choice. Attractive style and good equipment. Luxury lovers will love the Limited and Overland versions. The American SUV only seems huge. The length of 4.75 meters allows you to comfortably accommodate only four – the average in the back seat is uncomfortable. But acceptable dimensions allow you to confidently move around the city. Additional advantages are comfortable seats with electric drive, adjusting the steering wheel in two planes and clear instruments. But there are also disadvantages. For example, not too spacious salon. There's not much room in the back row. In versions with a hatch (option) limited upper space above the head. The quality of finishing materials leaves much to be desired - signs of wear appear after 100,000 runs. The leather of the chairs does not have the highest strength. Fortunately, this is mostly true of pre-restyling copies. The trunk volume from floor to ceiling is 978 liters. The useful volume is actually limited by the height of the windows, but in consolation get a full-size spare wheel - under the bottom, compartments for storing things in the floor (available when reclining the sofa cushion) and a separately opening window of the rear door.

Engines

The Jeep Grand Cherokee has an interesting engine lineup. It is opened by a Mercedes diesel engine - 3.0 V6. The engine has good traction, especially at high revs, and works quietly and gently. But fuel consumption is relatively high: it is very difficult to keep to 10 l / 100 km outside the city. The average consumption of about 12.5 liters is quite justified. In the diesel engine sometimes the attachment equipment fails, the incandescent candles can stop warming (the module is defective), the flaps in the intake manifold are damaged. The biggest drawback of gasoline engines is the significant fuel consumption. 3.7-liter modifications were imported from the United States. They are not dynamic enough, but for quiet movements the potential of the atmospheric engine is quite enough. It is much more pleasant to move on a car with a V8 engine with a working volume of 4.7 liters or 5.7 liters. Even the manufacturer does not hide that such a unit in the city will consume at least 20 l / 100 km. Real figures with a 5.7-liter engine reach values of 40 liters. During a leisurely trip, you can achieve a result of 12 liters, thanks to the operation of an intelligent system that disables 4 cylinders. After restyling, the power of the engines has grown: 4.7 liter version from 231 hp to 303 hp, and 5.7-liter from 326 hp to 334 hp 4. 7 V8 Power Tech has a simple design: cast-iron block and heads with 2 valves per cylinder. Characteristic malfunctions: corrosion of the block head, deformation of exhaust collectors and oil leakage. The version, powered by the V8 6.1 engine, was developed by Street and Racing Technology (SRT).

Design features

All versions are equipped with a 5-speed automatic. And although today such a number of gears is no longer impressive, it is worth noting that the box works quite gently and almost does not slow down the car.

The chassis has undergone more significant changes compared to its predecessor: the front axle has become completely independent, and the steering wheel has received a rack-type circuit. Innovations made the SUV more pleasant and obedient in management. However, there was a hard bridge behind. However, the comfortable suspension settings and high tire profile are ideal for our roads.

The Grand Cherokee, like its predecessor, has a self-supporting body reinforced by a robust integrated frame. Such a system, on the one hand, allows more efficient use of the internal space, on the other hand, increases the resistance of the body to off-road loads.

Behind is a hard bridge (springs). Many cars have serial protection.

Transmission

The Jeep Grand Cherokee is not just for asphalt comfort. The designers also promised outstanding abilities on the ground. A lot depends on modifications. You can even come across 2WD! These are imports from the US, most often with a 3.7 liter engine. But having only one axle leading a famous car is just not decent.

Several types of transmissions were used. Quarda-Trac I - permanent drive to the rear wheels with the connection of the front with a coupling. This SUV does not have a gearbox (which means there is no small T-shaped lever). The effectiveness of such a scheme leaves much to be desired.

It is much better when the car is equipped with a Quadra-Trac II. The thrust distribution is the responsibility of the clutch, but if necessary, the driver can use a gearbox, and then the drive between the front and rear axles is locked mechanically.

It is even better when there is a Quadra-Drive II sign next to the lever. This means that the car has three electronically controlled differentials. The off-road potential of this scheme is fantastic. From damage from below protect powerful shields, installed as an option. But there are disadvantages: rather large bumpers are easy to damage (they are located below the protection), and the ground clearance is not too high (190 mm instead of the promised 209 mm).

The most advanced all-wheel drive system can be recognized by the characteristic T-shaped chrome lever.

For the Jeep Grand Cherokee, you can buy many tuning elements (bumpers, discs, suspension). The list is not as rich as the list of the most popular models.

What do you want to pay attention to?

Over time, corrosion pockets appear in the lower part of the body - not too large, but the car is not too old. Official dealers in the framework of the service action updated the software module FDCM – fought with the spontaneous disconnection of the “distribution”. 2. Diesel engine is a source of considerable expenses, especially in cars with a mileage of more than 200,000 km. A turbine with variable geometry is not always repairable. The turbocharger control unit, unfortunately, does not change separately. 3. The weakest element of the chassis is the steering rack, which can knock after 50,000 km. The cost of repairs is about $ 200, the new one is much more expensive - almost $ 1000. Most preferred SUVs with a transmission Quadra-Drive II. However, it is worth to be wary of electric motors in bridges (if a malfunction, the “4x4” signalizer will light up). The cost of repairs is about $100. Make sure during the test drive in the absence of glitch and foreign knocks, and during the inspection - in the absence of leaks from the transmission elements. Due to the large mass of the SUV, ball and steering rod tips are relatively quickly surrendered, brake discs are overheated and deformed. ABS sensors are also being used. There are cases of premature wear of front shock absorbers. The power steering pump also sometimes causes trouble. When functioning in pair with motors of 4.7 and 5.7 liters, tremors are often observed during switching. The automatic transmission failure will be expensive. If the sensors on the control board break down, then you will have to pay about $ 300 for repairs.

The Jeep Grand Cherokee III is a popular car that can be purchased at an affordable price. The cheapest ones can be a trap. Let repair SUV is inexpensive and not complicated, but when problems accumulate a lot, the bill turns into a tidy sum.

Be careful – do not buy a copy with a drive only on the rear axle. Compared to its predecessor, the durability of the suspension has increased, but the developed electronics like to “prank”. Among the power units, V8 gasoline engines are most preferred, although they are not economical.
