Owners Nissan Primera The second generation (P12) is often faced with design features of the rear end. This generation, produced from 2001 to 2007, is famous for its practicality, but the trunk opening mechanism has a number of specific nuances that you need to know about in advance. The comfort of using a car in everyday life depends on the serviceability of this system.
Sedan luggage compartment Primera P12 has a volume of 470 liters, which is an excellent indicator for its class. However, wagon owners get even more space, making them popular for family trips. The problem is often not the volume, but the reliability of the lock and hinges, which wear out over time due to lack of proper maintenance.
Design features and luggage compartment volume
When designing the body, engineers paid special attention to functionality. In a sedan Primera P12 The rear window opens separately from the trunk lid, which is a rarity in the modern automobile industry, but very convenient for quickly loading small items without opening the entire hatch.
The main lid rises on fairly high hinges to provide a wide opening. This allows you to load large items such as baby strollers or bicycles without disassembling them. However, the high roof requires caution when parking in low garages to avoid damaging the paintwork.
- 📦 The volume of the sedan is 470 liters, and the station wagon - up to 500 liters with the seats folded.
- 🔒 The lock has two levels of protection: the main lock and an additional tongue.
- 🛠️ The lid lifting mechanism is based on two gas shock absorbers that require replacement when worn.
If you frequently transport cargo, pay attention to the condition of the floor covering. Moisture often accumulates there if the glass O-ring has lost its seal. This can lead to corrosion of the trunk bottom, which is a hidden but dangerous defect.
⚠️ Attention: If you notice traces of water in the spare tire well, immediately check the rear window seal and the drainage holes in the trunk lid.
Diagnosis of problems with electronic lock and drive
The most common problem owners have is the failure of the electric lock drive. IN Nissan Primera P12 a complex control system is used, where the signal from a button on the key or interior is sent to the body control unit. Failures in this circuit can lead to the door simply not opening.
The first thing to do is check the fuse responsible for the central locking system. This is often an element labeled DOOR LOCK in the interior fuse box. If the fuse is intact, the problem may be in the actuator (motor) itself, which eventually stops working due to wear on the gears.
Sometimes the reason lies in the oxidation of the contacts in the connector located in the rubber corrugation between the body and the trunk lid. Constant vibrations and temperature changes destroy the insulation of wires, causing a short circuit or open circuit.
- 🔍 Check for voltage at the actuator terminals when pressing the open button.
- ⚡ Inspect the wires in the corrugation for fractures or oxidation of contacts.
- 🔑 Try opening the trunk with a mechanical key to prevent electronics from breaking.
If there is electricity, but the motor does not turn, the mechanism may be jammed. In this case, only dismantling the cover casing and replacing the drive will help. Do not try to force the lock out, as this may cause deformation of the plastic and metal.
- The lock won't open
- Shock absorbers are weakened
- The casing is torn
- No problem
Instructions for replacing the mechanical opening cable
In case of complete loss of electronics or during emergency opening from the passenger compartment, the mechanical drive cable plays a critical role. It is located behind the cover trim and connects the inner lever to the locking mechanism. Over time, the cable can stretch or break, making it impossible to open from the inside.
To replace it, you need to remove the plastic trim on the trunk lid. It is held in place by plastic clips, which can become fragile after years of use. Use a flathead screwdriver to pry the clips around the perimeter carefully.
☑️ Preparing to replace the cable
After removing the trim you will see the lock mechanism. The cable is secured with a special plastic clamp. You need to snap it off and pull out the old cable. The new element must be original or a high-quality analogue, since cheap spare parts often have increased play.
Installing a new cable requires patience. You need to pass it through the protective corrugation and fix it in the lock mechanism, and then on the internal lever. Make sure that the cable is not too tight, otherwise it will constantly keep the lock under tension.
⚠️ Attention: When assembling the trim, be sure to check the operation of the lock before finally snapping all the clips into place. It will be difficult to fix the error after assembly.
Secrets of dismantling the casing
Plastic clips on Nissan Primera P12 often get stuck. Before starting work, it is recommended to warm them slightly with a hairdryer or use special pullers so as not to break the plastic. If the clip is broken, do not try to put it back - buy a universal set of clips for foreign cars, this will save time.
Repair and replacement of gas lifts (shock absorbers) of the cover
Over time, the gas shock absorbers lose pressure and the heavy trunk lid begins to lower on its own. This is not only inconvenient, but also dangerous: the lid may fall on your head at the most inopportune moment. On Primera P12 shock absorbers with a compression force of about 600-700 N (Newton) are used, depending on the configuration.
Replacement is quite simple. The shock absorber rod is mounted on hinges with plastic clips. It is necessary to carefully press the lock using a screwdriver and remove the old gas lift. Installing a new element requires effort, so it is better to do it together or use special clamps.
It is important to choose the right new shock absorbers. Too weak ones will not lift the cover, and too strong ones can quickly break the plastic fasteners on the body. Focus on the parameters of standard parts or proven replacement brands.
- 🛠️ Use a screwdriver with a thin blade to press out the clamps on the rod.
- ⚖️ Check the strength of new shock absorbers before purchasing (marking on the body).
- 🧹 Clean the mounting points from dirt and rust before installing new parts.
Before purchasing new gas lifts, measure the distance between the centers of the hinges in the open and closed positions. This will help you choose the perfect length, as there are many fakes on the market with the wrong sizes.
Eliminating play and squeaks in trunk hinges
Long-term use leads to the fact that the lid hinges begin to play. This manifests itself in the form of squeaks when opening and closing, as well as the appearance of gaps between the lid and the body. In advanced cases, play can lead to the lock being skewed and making it impossible to close.
To fix the problem, you need to lubricate the hinges. Use special joint lubricants, such as lithium or graphite based. Do not use WD-40 for long-term lubrication, as it washes out quickly and does not create a protective film.
If lubrication does not help, the hinge pin or bushing may be worn. In this case, the entire hinge assembly will need to be replaced. On Nissan Primera hinges often rust, so before installing new parts it is worth treating them with an anti-corrosion compound.
It is also worth checking the condition of the rubber seals around the perimeter of the trunk. If they become tanned or torn, this leads to the penetration of dust and moisture, which accelerates the wear of the mechanisms.
Regularly lubricating the hinges and checking the condition of the seals is the cheapest way to extend the life of the trunk mechanism and avoid costly repairs to the lock.

How to distinguish an original from a fake
Original gas lifts have a clear laser engraving of the number on the body and a high-quality rubber coupling at the end. Counterfeits often have blurred fonts and cheap plastic fasteners that break the first time you try to install them.
Tuning: installation of door closer and lighting
Many owners Primera P12 strive to improve the comfort of using the trunk by installing an electric closer. This device automatically closes the lid if you forget to do so, or pushes it all the way when you press lightly.
To install the closer, you will need to remove the trim and lay the wiring from the control unit to the lock mechanism. The process requires electrical skills, as the power and control signal must be connected correctly. Installation errors may result in a short circuit.
Another popular modification is the installation of additional LED trunk lighting. The standard lamp is often dim and burns out quickly. Replacing with bright LED modules significantly improves visibility at night.
- 💡 Choose lamps with W5W or T10 base, depending on the standard socket.
- ⚙️ When installing a closer, use a relay to protect the circuit from overloads.
- 🔧 Lay wires in corrugation along with standard wiring to protect against chafing.
Neon stripes or bulky mechanisms can ruin the appearance of the interior. Use hidden installation and high-quality materials.
⚠️ Attention: When installing the electric drive of the closer, make sure that it does not block the operation of the standard lock in an emergency. The system must be able to be opened manually.
By following these guidelines, you will be able to maintain the trunk of your Nissan Primera P12 in excellent condition for many years. Regular maintenance and timely replacement of worn parts is the key to the reliability and safety of your car.
How to open the trunk if the battery is dead?
If the battery is low, the electric lock will not work. You need to open the back seat, climb into the trunk and press the special emergency release lever, which is located inside the trunk lid. It is usually marked with a luminescent mark.
Why doesn't the trunk close all the way?
Most often this occurs due to wear on the lock mechanism or dirt getting into the tongue. Try lubricating the lock with silicone grease. If this does not help, the lock cylinder may need to be adjusted or replaced.
Is it possible to put a trunk from a station wagon on a sedan?
No, that's impossible. For sedan and station wagon Primera P12 completely different hinge fastenings and lid geometry. The window lift mechanism is also different, if provided for by the design.
How much does it cost to repair a trunk lock?
The price depends on the complexity of the problem. Replacing the cable will be inexpensive, while replacing the entire electronic actuator and electrical diagnostics will require more expense. Focus on the cost of spare parts and service work.
How often should hinges be lubricated?
It is recommended to carry out preventive lubrication of the hinges and lock every 6-12 months, especially before the winter season. This will prevent jamming and corrosion of the mechanisms.
