The main problems and shortcomings of Nissan Theana 2 with a run
Nissan Theana - a car of medium business class, which is manufactured from 2003 to the present. Thanks to its expressive appearance, its rich equipment, good running characteristics and reasonable price, Teana is one of the best-selling cars in this segment, competing with such models as Toyota Camry. And, here's how things stand with the reliability of the car, and what should be noted when choosing a Nissan Theana 2 with a run in the secondary market, you'll find out by reading this article.
Weaknesses and weaknesses Nissan Theana 2 with a runThe paintwork coating of the body is rather gentle, as a result, chips and scratches appear even from a slight effect on the paint. Most often, the hood is prone to chipping, because of this, on most instances, it is not in its home paint. As for the quality of the metal body, it suffers pretty much in our operating conditions, especially in the places of chips. The most susceptible to corrosion: the hood, boot lid, the upper and lower edges of doors, thresholds and wheel arches.On the dorestayling versions, special attention is required seams and the floor of the trunk, the bottom of the car and suspension elementscovered with rust). Not famous for the durability and chrome body elements (cloudy and corroded). Also, on cars older than 6 years, the front optics begin to grow dull (To prolong the life of the optics it is sufficient to glue a protective film on it). To the weak points can be attributed windshield (quickly becomes covered by chips and scratches, cracking when the temperature drops sharply) and door handles (When the door is freezed, it will not be difficult to break the handle).EnginesNissan Teana 2 was completed only with gasoline engines - a row "quartet" 2.5 (167 hp) and V-shaped "six" in volume 2,5 (182 hp) and 3,5 (249 hp). All powertrains are reliable enough, but V6 engines deserve the most attention, as they are considered the most successful in the last decade. The declared resource of V6 engines is 300-350 thousand km, but, as experience has shown, with proper maintenance and proper operation, the motor, without major repairs, can serve up to 500,000 km of run. The main problems faced by owners are more often associated not with the power unit itself, but with its attachments. So, for example, in winter time there are problems with cold starting of the engine because of the fragility of the catalysts. To tighten with the replacement of catalysts is not worth it, because when it is destroyed, the ceramic particles fall into the cylinder and significantly reduce the piston life. One of the most problematic places is the oil pump, its resource rarely exceeds 100-120 thousand km, if the oil is replaced in an untimely time, on 60,000 km of run. To prolong the life of the pump, it is necessary to change the oil at least every 10-15 thousand km (especially if the car is operated in urban mode). Official service recommends installing expensive iridium candles on the motor, but, this makes no sense, since they do not last much longer than usual. Owners of cars with a 3.5 engine often have to change engine supports (once in 40-50 thousand km), while owners of cars with a motor 2.5 do this procedure once in 150-200 thousand km. These motors are equipped with a chain drive timing, as a rule, this node does not require interventions up to 170-200 thousand km (replacement of chain and tensioners is required). The weakest power unit 2.5 is less durable than the more powerful units (The resource before the capital is 250-300 thousand km). Common shortcomings of this motor include a small resource of timing chains, phase shifter and oil pump, they fail at a run of 120-150 thousand km. The piston group at large runs is prone to zakoskovke, as a result, the engine begins to eat up oil. From the general features of all engines, it is possible to note the oil leaks through the cylinder head gasket, after 120-150 thousand km the oil consumptionreplacement of pistons of rings is required). Also, it should be taken into account the fact that the engines are not equipped with hydraulic compensators and require valve adjustment at least every 70-90 thousand km. If the engine starts to idle at idle, and acceleration occurs with jerks, it is necessary to flush the injectors and the throttle. If this does not solve the problem, you will have to reflash the engine control unit. All power units are afraid of overheating, to avoid big trouble, many experts recommend changing the thermostat every 50-60 thousand km (It breaks down on a run of up to 80,000 km) and wash the radiator 1-2 times a year. Special attention should be paid to engine sensors, lambda sensors and temperature sensors on pre-stylized specimens, and there are wiring damage. One of the problematic places is considered to be radiator fans: they also supply their bearings and electric drives, so make sure that they are working when buying.
TransmissionNissan Teana 2 was equipped with only automatic transmissions CVT - stepless variator Jatco JF011E, Jatco JF016E and JF010E. Counting on a large service line transmission is not worth it, since its resource, on average, is 150-170 thousand km, even the regular replacement of the company's lubricant does not help. Repair only briefly prolongs the life of the transmission, therefore, many experts recommend immediately changing the box. Most often with the failure of the variator, the owners of post-restyling specimens collide. The fact is that the manufacturer made constructive changes to the cooling system of the box, removing one of the three radiators, as a result, the unit overheats when the load lasts for a long time. At cars on which the box was overheated, at high engine speeds the transmission howls and twitches during acceleration.
Oil in the box should be changed at least every 30,000 km, otherwise premature wear of the oil pump and hydraulic unit plugs is unavoidable. Often, to a run of 100,000 km, on cars whose owners like to "pozazhagat", you have to change the belt. For all-wheel drive versions, the clutch of the rear wheel drive clutch is added to the number of nodes with a limited resource, which can be burned during frequent races on ice or "races" in the summer. For the replacement of the clutch will have to lay out 600-800 cu.Problems and disadvantages of undercarriage Nissan Teana 2 with a runSuspension of Nissan Theana 2 independent, without any complicated design solutions: front - MacPherson, rear - multi-lever. If we talk about its reliability, then, despite its simplicity, a couple of weak points in it yet, are present. Most often bother the pillars and bushings of the stabilizer, replacement every 20-30 thousand km. Once in 40-60 thousand miles remind themselves of the tips of the steering rods. On the run of 80-100 thousand km will require more serious costs, because by this time the ball bearings, steering rods, silent drives of the front levers, and levers of the rear suspension go out of order. Shock absorbers, bearing and hub bearings are able to hold up to 150,000 km. When operating the car, it is necessary to monitor the gangway, because in Tehan it regularly goes astray (check every 10-15 thousand km). In the steering mechanism, the GUR mechanism most often bothers. The problem is that the high-pressure hose is close to the exhaust manifold, because of overheating, it begins to crack and leak (replacement of the hose costs on average 200-250 US dollars.). There are complaints and on the steering rack, problems with the rake can begin on the run 70-80 thousand km (there are drips and knocking when driving on a rough road). The braking system is generally reliable, except that on vehicles with four-wheel drive one can find increased wear of the front brake hoses.SalonThe quality of the interior materials of the Nissan Theana does not exactly match the class of the car. A naughty driver's seat is more likely a rule than an exception, and even a string of seams with a large run literally sprawl. Closer to 100,000 km there are worn on the handlebars. Also frustrating is the fact that the steering wheel does not have adjustments to take off and the monochrome display of the audio system in the base complete sets, the same was installed on the Opel 10 years ago. And, here, the sound quality of acoustics and noise isolation pleasantly surprised, but, nevertheless, up to the premium level of European models is still not reaching. There are problems with the electrician, more often owners complain about the failure of the window control module, malfunctions in the multimedia system, not infrequently there are errors in the operation of the climate system. In most cases, you need to re-flash the blocks to fix problems. When inspecting a car with a mileage of 150000 km and more, listen to how the engine works, if there are extraneous noise, then soon it will have to be changed.
In addition to comfort, good driving characteristics and a presentable look, the Nissan Teana 2 boasts an acceptable reliability. If you compare this car with European competitors, then, in many respects it loses to such brands as Mercedes, Audi and BMW, but, it is more than payback with low cost of maintenance and repair.
