Typical Problems with Nissan Vehicles
Any car needs regular maintenance. Especially since many car brands have their own typical problems that require special attention. These may be flaws in the engine, running gear, the operation of the heating system and other units. Because of the typical problems there are frequent breakdowns, which did not bypass such serious cars as Nissan. Malfunctions of cars of this brand will be discussed in more detail in the following article.
Causes of malfunction of Nissan engines
One of the most serious and costly problems for the owner – engine malfunctions. To the main reason that causes engine failures, you can attribute a violation of the rules of operation of the car. Thus, more often than not, it is the owner’s own fault for having to do Nissan repairs.
Popular cases include:
– Failure to change the engine oil on time;
– Prolonged intervals between vehicle maintenance;
– Prolonged use of the engine in extreme conditions;
– Irregular flushing of the injection system.
Let’s define the most frequent breakdowns of Nissan engines, which can be referred to the typical ones.
Timing chain stretching
A stumbling block between the car and the owner becomes a burning “Check” light. It usually occurs after 150 thousand km of run. A characteristic sign of Nissan’s problems is the fact that the car starts poorly when starting from cold. Computer diagnostics shows that the fault lies in the phase and crankshaft sensors. At the same time, no positive dynamics is observed after replacement. The owners of Nissan Qashqai and Teana assert on forums that the reason is in stretched chain of timing. Indeed, in most cases, the work of the engine becomes normal after replacement. Read here about cold air intakes for Nissan.
Block head defect
Constantly high loads on the engine of a Nissan car can lead to failure of the cylinder head. Diagnosing and replacing this part can be a significant blow to the car owner’s wallet. The main symptoms of such damage include:
– A high concentration of whitish smoke from the exhaust pipe with a characteristic unpleasant odor;
– Formation of condensate at the outlet with a luscious taste;
– The engine is trembling and the spark plugs are smoking;
– Oil level is elevated, color in the crankcase becomes turbid (due to mixing with the coolant/antifreeze);
– Exhaust vomits into the expansion tank when overdriving at idle speed.
Such malfunctions of Nissan Almera an- d other models of the brand require urgent connection of specialists. Comprehensive diagnostics on modern equipment will eliminate the cause and consequences of problems with your car.
Excessive oil consumption in the engine
Increased fluid consumption can happen due to several direct factors. Common ones include:
– A faulty crankcase gas drain valve;
– Wear of the timing gear oil caps;
– Wear of piston rings.
Untimely oil replacement or low oil quality can significantly affect the performance of the engine. In addition, it becomes necessary to overhaul even such powerful SUVs as Nissan Pathfinder or Terrano.
Clogging of idle speed regulator
GA14DE and GA16DE engines often have a problem associated with a clogged idle speed regulator. This also applies to the mass air flow sensor. Most frequently this problem occurs in vehicles with mileage over 100,000 km. The idle speed is lost and the normal operation of the engine is disturbed. To eliminate this problem, it is advisable to flush with special agents and clean the regulator. After that you can adjust the idling speed.
Displacement of the indicators of the mass air flow sensor
Nissan X-trail, Tiida often have shifted indicators of the mass air flow sensor. The problem can be determined by connecting a scanner or checking the fuel composition according to the factory values. If this malfunction is not corrected in time, it will lead to more serious problems and engine overhaul.
Throttle body contamination
Newer engines have a throttle body that is often contaminated. This causes the control unit to start in emergency mode. Thus, the motor does not respond to the accelerator pedal. Such malfunctions lead to the failure of the electronics, as well as other equally serious defects. Read more here.
These are not all the typical malfunctions of Nissan cars, which require increased attention from the owner. It is especially worth emphasizing the engine of the chosen car, which should be diagnosed and repaired as needed.
