trunk Nissan X-Trail - a unit that is subjected to daily loads: from sharp claps of the lid to moisture entering the lock mechanism. When it stops opening, it paralyzes the daily operation of the car. In 80% of cases, the problem is solved without visiting a service center, but to do this you need to accurately diagnose the cause - be it frozen drive, blown fuse or mechanical wear of rods.
In this article we will analyze the specifics of faults for generations T31 (2007–2013), T32 (2013–2020) and T33 (from 2021) as their locking and wiring designs are different. You will learn how to open the trunk in emergency mode, what parts break most often after 100,000 km, and why sometimes a simple reboot of the car’s electronics helps. Let's start with the most obvious reasons - they are often overlooked even by experienced drivers.
1. Electrical faults: fuses and relays
If the trunk Nissan X-Trail does not respond to the button on the key or the interior key, first check - fuse box. In 30% of cases the problem lies in a blown fuse F37 (10A) (for T31/T32) or F28 (7.5A) (for T33). These fuses are responsible for the central locking circuit, including the trunk drive.
Where to look:
- 🔧 T31/T32: block under the steering wheel, to the left of the pedals (remove the cover, press the latches). fuse
F37located in the top row, third from the right. - 🔌 T33: unit in the glove compartment (open the glove compartment, remove the cover from the back). fuse
F28- second in the bottom row. - ⚡ Central locking relay (if the fuse is intact): on T31 this is
R12, on T32/T33 —R7. Check with a multimeter or replace with a known working one.
If the fuse blows again after replacement, look for short circuit in the wiring. Most often, the problem is in the harness under the rear door trim - there the wires fray due to constant opening. You can check this by pulling the harness with the ignition on: if the fuse trips, the insulation is damaged.
⚠️ Attention: On X-Trail T33 with the system ProPILOT A blown trunk fuse may prevent the 360° camera from working. Before replacing, turn off the ignition for 10 minutes - this will clear errors in the control unit.
2. Mechanical failures: lock and rods
Mechanical problems occur when the trunk does not open either with a button or manually. Main culprits:
- 🔒 Wear of plastic rods (especially on T31 until 2010). They crack from the cold or dry out over time. Symptom: When you press the button, you hear a click, but the lid does not lift.
- 🔩 Rotating the lock shaft. The shaft connects the outer handle to the mechanism - if it turns, the handle goes “idle”. Often occurs after careless opening in winter.
- 🧊 Mechanism freezing. Moisture enters the lock through the seals, and at −10°C and below ice forms. Symptom: The handle is difficult to move or blocked.
How to check traction:
- Remove the rear door inner trim (unscrew the 6 plastic clips and 2 screws under the handle).
- Find two rods: one goes from the handle to the lock, the second from the drive to the lock.
- Pull them with your fingers: if the rod crumbles or comes off the fastening, it needs to be replaced.
For T32 And T33 There is a nuance: the rods are metal, but are attached through plastic bushings. These bushings wear out, and the thrust begins to “walk”. The solution is to replace the bushings (article no. 40520-4M000 for T32, 40520-4M100 for T33).

3. Drive and actuator malfunctions
The electric drive (actuator) of the trunk is a weak point X-Trail of all generations. It fails due to:
- 💧 Corrosion inside the mechanism (moisture entering through a leaky seal).
- 🔋 Wear of the electric motor brushes (a characteristic sign: the drive hums, but does not open).
- 🔌 Broken power supply (check the connector on the actuator - contacts often oxidize).
How to diagnose:
- Remove the rear door trim.
- Find the actuator (black plastic block with a connector screwed to the lock).
- Disconnect the connector and feed directly
12Vfrom the battery to the drive contacts (polarity is not important). If the motor does not spin, the actuator is dead.
On T31 The actuator often breaks down 28501-4M000, on T32/T33 — 28501-4M100. The average price of a new one is 3,500–5,000 rubles. You can try to restore the old one: disassemble, clean the brushes and lubricate lithium grease (not WD-40!).
⚠️ Attention: On X-Trail T33 with electric trunk lid (optional) Easy Lift) a faulty actuator can block the operation of the entire central locking system. If the problem persists after replacement, reset the unit BCM through a diagnostic scanner.
Check fuse F37/F28
Ring the circuit from the control unit to the actuator
Apply 12V directly to the drive connector
Inspect the rods for wear or breakage
Check the door seal for leaks -->
4. Problems with the key fob and keyless entry system
If the trunk does not open from the key fob, but responds to the interior button, the fault is remote control or immobilizer unit. On X-Trail most often found:
- 🔋 Low battery in the key fob (even if the indicator is on, the voltage may not be sufficient to transmit the signal).
- 📡 Damaged signal reception antenna (located under the rear bumper, often rots from salt in winter).
- 🔐 Failure to synchronize the key fob with the unit NAT (on T32/T33 reprogramming required via Nissan Consult).
How to check:
- Replace the battery in the key fob with a new one (
CR2032). - Bring the key fob close to the back door and press the button - if it works, the problem is in the antenna.
- Try opening the trunk using a different key fob (if available).
If the key fob does not sync, perform a reset:
1. Вставьте ключ в замок зажигания.2. Поверните в положение ON (не заводите).
3. Нажмите кнопку открытия багажника на брелке 6 раз подряд.
4. Выключите зажигание, выньте ключ.
5. Повторите попытку открытия.
On T33 with the system NissanConnect You may need to restart the multimedia unit: hold down the power button for 10 seconds, then repeat the key fob synchronization.
5. Emergency trunk opening
If the trunk is locked and there is access to the interior, use emergency rope. It is located:
- 🚗 On T31: under the rear seat (recline the backrest, remove the floor hatch). A cable with a red handle leads directly to the lock.
- 🚙 On T32/T33: behind the rear door trim (you need to remove the plastic panel from the inside). Orange cable.
If the cable is torn or is missing (this happens on restyled T32 after 2017), proceed as follows:
- Remove the rear shelf (it is secured with 4 plastic clips).
- Get to the lock through the access hole.
- Manually slide the latch with a screwdriver or pliers.
For X-Trail T33 with electric lid (Easy Lift) emergency opening is more difficult: you need to turn off the power to the actuator (remove the connector) and manually lift the cover, overcoming the resistance of the springs. After this, be sure to check microswitch in the lock - it can stick and block re-opening.
What to do if the cable is broken and the casing cannot be removed?
As a last resort, you can drill a hole in the rear door trim (in the lower corner, where it is not visible) and insert a wire there to move the latch. After opening, seal the hole with sealant or install a rubber plug.
6. Prevention and care of the trunk mechanism
To avoid problems with your trunk, follow these simple rules:
- ❄️ Treat the castle in winter silicone grease (not graphite!) every 2 weeks. This will prevent freezing.
- 🔧 Check once a year cable tension and the state of traction. On T31 the rods are fragile - it is better to replace them with metal analogues (
40520-JK00A). - 🚿 After washing, dry the rear door seal with compressed air (especially if the car has Easy Lift).
- 🔋 Once every 2 years, clean the actuator contacts from oxidation (use
CRC contact cleaner).
For X-Trail T33 with electric lids add to the list:
- 🔄 Lubricate once every 6 months gas strut guides (use
LIQUI MOLY LM47). - 📱 Update the unit’s firmware BCM (via dealer). In older versions of the software there are glitches with trunk control.
If your X-Trail often stands outside in winter, install heated trunk lock (set 28505-4M000 for T32). It turns on together with the heated glass and prevents the mechanism from icing.
On T31 with a mileage of more than 150,000 km, it is recommended to replace all plastic rods with metal ones - this will eliminate the risk of breakage and eliminate the need to disassemble the door in cold weather.

On X-Trail T33 with the system ProPILOT A trunk malfunction can disable the 360-degree cameras. Always check for errors through the menu Settings → System → Diagnostics after repair.
FAQ: Frequently asked questions about the trunk of the Nissan X-Trail
The trunk can only be opened from the interior, but not with the key. What's the matter?
Most likely, the problem is in the key fob signal reception antenna (located under the rear bumper). Check its circuit: contacts often oxidize or wires fray. The key fob itself may also be faulty - try reprogramming it through the menu Settings → Security → Key synchronization (for T32/T33).
After replacing the actuator, the trunk opens but does not close. What to do?
The reason is an uncalibrated lock microswitch. On T32/T33 you need to reset the unit settings BCM:
- Disconnect the battery for 10 minutes.
- Plug it back in and turn on the ignition.
- Open and close the trunk 3 times in a row using the button in the cabin.
If it doesn't help, check limit switch on the trunk lid - it may be dirty or broken.
Is it possible to open the trunk if the battery is dead?
Yes, but the method depends on the generation:
- T31: Use the emergency cable under the rear seat or mechanically slide the latch through the hole in the trim.
- T32/T33: if the lid is electric, you will have to recharge the battery at least until
11.5V(minimum voltage for actuator activation).
On T33 with Easy Lift If the battery is discharged, the cover may become locked; in this case, an external power source is required.
Why does the trunk open by itself?
This is a typical problem X-Trail T32 with a faulty central locking control unit (BCM). Reasons:
- Short circuit in the actuator circuit.
- Firmware failure BCM (can be treated by flashing through Nissan Consult).
- Moisture gets into the unit connector (located under the front panel).
Workaround: Turn off the fuse F37, but then the central locking will stop working.
What lubricant should I use to treat the trunk lock in winter?
Use silicone lubricants (For example, WD-40 Specialist Silicone or LIQUI MOLY Silicone-Spray). They do not freeze and do not attract dust. It is strictly forbidden to use:
- Graphite lubricants (clog the mechanism).
- Machine oil (thickens in cold weather).
- WD-40 classic (washes out factory lubricant).
Treat the lock from the inside by removing the casing - this way the lubricant will get to all the rubbing parts.
