Legendary sedan Nissan Almera the second generation, known in the P12 body, remains one of the most popular cars in the secondary market of the CIS countries. It was nicknamed “indestructible” for its simplicity of design and maintainability, but even such machines have their own hidden drawbacks, which you should know about before purchasing or starting to operate.
Many owners are faced with the need to deeply understand the technical nuances of the model in order to avoid costly repairs. In this article we will analyze in detail the main components of the car, point out critical points of vulnerability and provide clear action algorithms to maintain reliability your transport.
Owners Nissan Almera P12 It is important to understand that a car requires a systematic approach to maintenance, and not just a routine oil change. Ignoring minor faults can lead to serious damage to the engine or suspension, so knowledge of the specifics of this model will be your main tool in the fight for the longevity of the car.
Engine and transmission: weaknesses and solutions
Under the hood Nissan Almera P12 most often found are naturally aspirated petrol units with a volume of 1.6 liters (QG16DE series) and 1.8 liters (QG18DE). These engines feature a reliable cast iron cylinder liner, but have a critical feature in the gas distribution system. The main problem is the stretching of the timing chain, which at runs over 100 thousand kilometers begins to make noise and can jump, which will lead to meeting of valves with pistons.
In addition to the chain, owners often complain of floating idle speed caused by contamination of the throttle valve or failure of the idle speed regulator. In some cases, it is necessary to replace the intake manifold gasket, which becomes dull over time and begins to suck in excess air, disrupting the mixture. Regular diagnostics adsorber and valve EGR will also help to avoid problems with the environment and engine stability.
The transmission is represented by both a 5-speed manual and a 4-speed Jatco automatic. The manual transmission is famous for its durability, but has a specific feature - wear on the first and reverse gear shift forks. The automatic transmission, although reliable, requires strict adherence to the oil change schedule, otherwise there may be jerks when switching modes and overheating of the torque converter.
Pay special attention to the cooling system. The radiators on these cars are prone to clogging from the inside, which can cause the engine to overheat even with a working thermostat. Visual inspection pipes for microcracks and regular checking of the antifreeze level are mandatory procedures.
⚠️ Attention: If you hear a metallic ringing when the engine is cold started, which disappears after 2-3 seconds, this is a sure sign of a stretched timing chain. Do not delay replacement, as a broken circuit is guaranteed to lead to a major overhaul of the motor.

Electrical and electronics: common failures and their elimination
Electrical diagram Nissan Almera P12 is quite simple, but has a number of “childhood diseases” that appear as the car ages. One of the most common problems is the failure of the central locking, caused by the failure of the actuators in the doors or the breakdown of the microswitch in the driver's door lock. Sometimes the problem lies in the oxidation of the contacts in the wiring harness passing through the rubber corrugation between the door and the body.
The immobilizer system can present surprises in the form of loss of communication with the key, which is often associated with a low battery in the key chip or a malfunction of the reader coil around the ignition switch. Owners are also faced with dashboard “glitches”: the arrows may spontaneously jump or go out when the brake is pressed, which indicates poor ground contact or a faulty fuse box.
Particular attention should be paid to the generator. The brushes and diode bridge in it have a limited resource, and if the voltage regulator fails, the battery can be overcharged, which is dangerous for all on-board electronics. To check the functionality of the generator, use a multimeter by measuring the voltage at the battery terminals with the engine running.
If you notice that the window regulators begin to work slowly or stop halfway, do not rush to change the motors. In 90% of cases, the problem is solved by lubricating the guides and cleaning the contacts in the control buttons. Simple maintenance is often cheaper and more effective than replacing components.
☑️ Electrical diagnostics
Body and suspension: combating corrosion and vibrations
Body Nissan Almera P12 has a medium degree of corrosion protection. The most vulnerable places are the sills, wheel arches and the bottom of the doors. In regions with harsh winters and aggressive reagents, these zones begin to rust within 5-7 years of operation. Critical place is the trunk floor under the spare wheel, where moisture often accumulates due to leaky rear door seals.
The car's suspension combines an independent multi-link rear axle and front MacPherson struts. The rear suspension design is complex and requires attention to the stabilizer bar bushings and control arm bushings. A characteristic knocking sound when driving over uneven surfaces often indicates worn shock absorbers or broken silent blocks of the front control arms.
The steering is represented by a rack and pinion mechanism. Steering rack leakage is a common problem, especially on cars with high mileage. Replacing the seals is possible, but it is often cheaper and more reliable to install a reconditioned rack or a new one. Also pay attention to the steering tips, which tend to play, causing the steering wheel to wobble at high speeds.
Don't forget about the braking system. The calipers on the rear axle can become sour due to lack of lubrication in the guides, which leads to uneven wear of the pads and overheating of the discs. Regular cleaning and lubrication of the pin guides will extend the life of the brake system by thousands of kilometers.
How to protect the body from corrosion
For maximum protection, it is recommended to remove the sills and treat them with an anti-corrosive agent from the inside, as well as regularly wash the underbody of the car in winter, removing salt and dirt, which accelerate the rusting process of the metal.
Comparative characteristics of engines and configurations
The choice of a specific configuration and engine affects performance and maintenance costs. Below is a table with the main technical data of the most common modifications Nissan Almera P12.
| Modification | Volume (l) | Power (hp) | Acceleration 0-100 km/h (sec) | Fuel consumption (combined) |
|---|---|---|---|---|
| Almera 1.6 SE | 1.6 | 102 | 11.5 | 7.5 l/100 km |
| Almera 1.8 SE | 1.8 | 116 | 10.2 | 8.2 l/100 km |
| Almera 1.5 dCi | 1.5 | 82 | 13.8 | 5.1 l/100 km |
| Almera 2.0 (N16) | 2.0 | 140 | 9.8 | 8.8 l/100 km |
The 1.5 dCi diesel variant, although less common, offers excellent fuel economy but requires quality fuel and timely replacement of the fuel filter. Gasoline engines are more unpretentious in terms of gasoline quality, but are inferior to diesel engines in dynamics and efficiency on the highway. The choice depends on your priorities: economy or dynamics.
The trim levels differ not only in engine size, but also in the presence of options such as climate control, leather upholstery and a navigation system. Older models often lack passenger airbags, which is an important factor when choosing a car for safety reasons.
When purchasing a used Nissan Almera P12, be sure to check the VIN for any accidents. Even if the body looks perfect, hidden damage to the side members can reduce body rigidity and safety in an accident.
Self-service: what you can do yourself
Owners Nissan Almera P12 often save on service costs by performing basic operations themselves. Changing the engine oil does not require special tools and takes about 40 minutes. It is important to use a high-quality filter and oil with a viscosity recommended by the manufacturer, usually 5W-30 or 10W-40 depending on the climate.
Replacing spark plugs is also affordable for everyone. To do this, you need to remove the decorative engine cover, unscrew the high-voltage wires and unscrew the old spark plugs. Pay attention to the electrode gap and the color of the carbon deposits, which may indicate problems with the engine. When installing new spark plugs, do not overtighten them so as not to strip the threads in the aluminum block head.
Replacing the air and cabin filters is a simple procedure that improves engine performance and cabin air quality. The filters are located in easily accessible places: the air filter is under the hood in a plastic box, and the cabin filter is behind the glove compartment on the passenger side. Regular replacement of these elements extends the life of the engine.
When replacing brake pads, be sure to check the condition of the brake discs. If the disc has deep grooves or wear of more than 1.5 mm, they must be replaced. Also be sure to clean the caliper guides and lubricate them with special high temperature grease before installation.
Replacing consumables yourself allows you not only to save money, but also to better understand the technical condition of your car, identifying potential problems at an early stage.
What to do if the car won't start?
Problems with starting the engine can have many causes, from a simple dead battery to serious malfunctions of the ignition system. First of all, check the voltage on the battery and the tightness of the contacts at the terminals. Oxidation or poor contact is often the reason why the starter turns but the engine does not catch.
If the battery is OK, pay attention to the operation of the starter and fuel pump. When you turn the key to the ignition position, you should hear a quiet hum from the pump from under the rear seat. If the pump does not operate, check the fuel pump fuse and relay in the mounting block.
In the cold season, the problem may be due to thickened engine oil or faulty glow plugs (for diesel engines). For gasoline engines, it is important to check the condition of the ignition coils and spark plugs. Sometimes the problem lies in the immobilizer, which does not recognize the key due to a low battery in the chip.
If the car does not start, but the starter turns the engine at normal speed, there may be a problem with the injection system or sensors. In this case, it is recommended to conduct computer diagnostics, which will show errors and indicate the specific faulty unit. Do not try to force start the engine if you do not know the reason, this may worsen the situation.
Emergency engine start
If the battery is completely discharged, you can try to start the engine using the “lighting” method from another car. Connect "plus" to "plus" and "minus" to engine ground, not to the battery of a discharged car.
