When there is no choice: is it worth buying Infiniti QX56
Probably, it is no secret to anyone that the Infiniti QX56 is a converted Nissan Armada, built, in turn, on the basis of the Titan pickup. A car was created for markets where big SUVs love – and in the list, besides America and the Middle East, there was Russia. The model was produced from 2004 to 2010 – and this means that the freshest cars are already in its tenth year, and the earliest more than fifteen. What is the risk of such an age when buying a used copy?
As befits an SUV created on the basis of a pickup, the QX56 is based on a ladder frame. This, in fact, is the first stumbling block when choosing a used sample: at the age of 10-15 years, any frame will remain in varying degrees of decay. In our case, the fact that Infiniti is rarely bought as an uncompromising SUV for regular trips to the curative mud, is on its hand, so the main enemies of the frame are salt and reagents. In addition to geometry and the absence of clearly rotten areas, it is worthwhile to check the safety of the frame number and its conformity with the documents: any problems here guarantee difficulties with registration – this is usually a refusal to perform registration actions.
The body is the next inspection point: it is impressive in length over 5.2 meters, but does not promise too much in terms of corrosion resistance. Much, of course, depends on the care: if you see a frank rust – go. And this pun is no joke: saving on the body does not promise anything good and on technique. The paintwork here is quite soft, and the brick-like body forms eloquently speak of aerodynamics, so chipping and pitting corrosion on the frontal part are almost inevitable. Worse, if the rust is on the edge of the windshield, sills and arches, and very bad, if the bottom of the found rotting. During the study tour, you should listen to knocks when driving over uneven ones – they can talk about problems with body-to-frame attachment pads, a set of which is so expensive that there are even craftsmen who make “self-made” supports. Well, it is worth checking the work and tightness of the hatch (including assessing the humidity of the carpet floor) and the good condition of the door handles – they have a tendency to freeze in winter, which is fraught with stretching and breakage of the cables.
But the chassis here is not at all what you expect from a relative of a large pickup truck. Both front and rear suspension are independent, with the front on double wishbones, and the rear gear is suspended on a massive stretcher, from which the wishbones also extend. This, on the one hand, significantly improves driving comfort, but on the other hand, it also increases the costs of maintenance and repair. By itself, the suspension element by element is not very expensive: for example, even the original front levers cost 7-12 thousand, which in principle can be considered a low price, but numerous non-original silent blocks are available for a few hundred rubles. The choice of front shock absorbers is limited to the original for 10 thousand and Kayaba for about the same money, and the back picture is slightly different: the original costs about 15 thousand, and Kayaba – about 7.
When inspecting the car, it should be borne in mind that for the QX56, as for a real “American,” various options for suspension refinement, including lift kits, as well as the possibility of a body lift, are offered – all of this in the correct dosage may well be useful. Separately, it is worth mentioning the system of automatic maintenance of the rear part of the body with air bellows – you should not be afraid of it either, but you still need to diagnose carefully, since even relatively inexpensive air bellows of 15 thousand apiece is a tangible one-time investment. The compressor costs more or less adequate money – 35-40 thousand, but it is also worth remembering that the body position sensor here will cost almost 20 thousand. Even when viewed from the bottom it is worth paying attention to the brakes: they are modest for a car weighing more than 2.5 tons, and especially the car before the 2008 restyling is very inclined to eat and jar the wheels. A well-maintained or even refined brake system is a good sign that the previous owner understood what he was dealing with.
On the move, you should definitely listen to the transmission – there are a whole set of different faults. The four-wheel drive on the QX56 is plug-in, and sometimes problems start already here – the inability to connect the front axle is usually associated with a malfunction of the electric servo drive in the handout or other electrical problems, including rotten wiring. If the front is connected, listen to the bridges during acceleration and coasting – the hum speaks of impending problems, and gearbox breakdowns are not uncommon both in the front and in the rear. By the way, when searching for a new gearbox in exchange for a broken one, it is necessary to take into account that restyled cars received different gear ratios – they, among other things, regularly put wheels 20 inches instead of 18. Clicks and knocks at the start could…
