Trunk lid <em>Nissan Almera G15</em>: device, faults and do-it-yourself repairs

Nissan Almera G15 is a popular sedan that is valued for its reliability and practicality. However, even such cars eventually develop problems with the trunk lid: it begins to sag, creak, or close poorly. In this article we will analyze the structure of the trunk lid Almera G15, typical malfunctions and methods for eliminating them - from adjusting the gas stops to replacing the lock.

Model feature G15 (2012–2019) is that its trunk is equipped with gas shock absorbers, which lose their tightness over time, as well as plastic hinges that are prone to wear. If you notice that the lid begins to close with a bang, sags on one side, or requires effort when opening, this is a signal to action. We will tell you in detail how to diagnose the problem and fix it without contacting service.

Trunk lid arrangement Nissan Almera G15: key elements

trunk lid Almera G15 consists of several main components, each of which can fail:

• 🔧 Gas struts (shock absorbers) - keep the lid in the open position. Over time, they lose pressure, causing the lid to fall or open jerkily.
• 🔑 Trunk lock — mechanical or electrical (depending on the configuration). Often suffers from corrosion or wear of the cylinder.
• 🔄 Hinges and hinges - plastic or metal parts on which the lid is attached. They may become loose or crack.
• 🛠️ Sealing rubber — prevents the ingress of moisture and dust. Over time it becomes dull and cracks.
• 🎛️ Microswitch — signals the closed position of the lid (affects the operation of the trunk lighting).

B Almera G15 company gas struts are used Stabilus or Sachs (depending on the year of manufacture). Their service life is about 50–70 thousand opening/closing cycles. The hinges are attached to the body with four turnkey bolts 10 mm, and to the cover - with two bolts under Torx T30.

Important: in some trim levels Almera G15 was installed electric trunk lock, which is controlled from a button on the key or from the interior. If it breaks, the lid may be locked in the closed position.

Typical trunk lid malfunctions and their causes

Owners Nissan Almera G15 Most often they encounter the following problems:

Malfunction	Reason	Consequences
The lid sags on one side	Failure of one gas stop	Risk of damage to hinges or body if dropped
Creak when opening/closing	Worn hinges or lack of lubrication	Accelerated wear of the mechanism, discomfort during use
The lid does not lock in the open position	Breakage of both gas stops	Unable to use trunk without support
The lock cannot be opened with the key	Corrosion of the cylinder or wear of the mechanism	Trunk access lock
Pop when closing	Stops or hinges are out of adjustment	Risk of damage to seal and body

Gas stops break especially often in winter: at low temperatures, the gas inside the shock absorber is compressed, and the stop stops supporting the weight of the cover. If you notice that the trunk begins to close with force or “slams,” this is the first sign that the stops require replacement.

⚠️ Attention: If the trunk lid Almera G15 started to close with a bang, don’t ignore the problem! This can lead to deformation of the hinges or even cracks in the body in the trunk area. This is especially dangerous for cars with plastic loops (installed on earlier versions G15).

How to adjust the gas stops Nissan Almera G15

If the trunk lid begins to close too quickly or does not lock in the open position, first try adjusting the gas stops. To do this, you do not need to remove the cover - just tighten the fasteners.

Step by step instructions:

1. Open the trunk and secure it in the upper position (for example, resting it on a rack).
2. Inspect the gas strut mountings:
   • Lower fastenings - to the body (bolts under 10 mm).
   • Upper fastenings - to the cover (bolts under Torx T30).

Loosen the bolts on the problematic stop (usually 1-2 turns is enough).

Adjust the position of the stop so that the lid opens smoothly and locks in any position.

Tighten the bolts firmly 15–20 Nm (do not overtighten so as not to break the thread!).

If the adjustment does not help, it means that the gas stops have lost their tightness and require replacement. The service life of the original Stabilus stops for the Almera G15 is about 5–7 years, after which they begin to “sag”.

Both stops must be the same length

There are no traces of oil on the stops (a sign of depressurization)

The fastening bolts are not loosened

Replacing gas struts with Nissan Almera G15: step by step guide

If the adjustment does not produce results, you will have to replace the gas stops. For Almera G15 original parts fit Nissan 80510-BM00A (left) and Nissan 80510-BM00B (right), as well as analogues from Stabilus, Sachs or Febi.

Required tools:

• 🔧 Key on 10 mm (for bottom bolts).
• 🔧Bit Torx T30 (for top bolts).
• 🧤 Gloves (gas stops can be dirty).
• 🛠️ WD-40 (if the bolts are sour).

Replacement procedure:

1. Open the trunk and secure it in the open position (for example, with a wooden block).
2. Remove the plastic plugs from the hinges (if any) - they are secured with latches.
3. Unscrew the lower bolts securing the stop to the body (the key is on 10 mm).
4. While supporting the cover, unscrew the upper bolts (bit Torx T30) and remove the old stop.
5. Install the new stop in reverse order. Important: Do not confuse the left and right stops - they have different lengths and compression forces!
6. Check the operation of the lid: it should open smoothly and lock in any position.

The cost of the original stops is approx. 2,500–3,500 rub. for a couple. Analogues will be cheaper: 1,200–2,000 rub. for both. When purchasing, pay attention to stop length (original - 420 mm folded) and effort (must be 400–500 N).

⚠️ Attention: When replacing gas struts with Almera G15 Never remove both stops at the same time! The trunk lid weighs approx. 15–20 kg, and without support it may fall sharply, damaging the hinges or the body. Always change the stops one at a time, securing the cover with a support.

Eliminating creaking trunk lid hinges

Creaking sound when opening or closing the trunk Almera G15 is a common problem that occurs due to:

• 🔹 Lack of lubrication in the loops.
• 🔹 Corrosion of metal parts.
• 🔹 Wear of plastic bushings (in models with plastic loops).

To eliminate the squeak, follow these steps:

1. Clean the hinges from dirt and old grease using WD-40 or kerosene.
2. Apply new grease:
   • For metal hinges - lithium grease (For example, LIQUI MOLY LM 47).
   • For plastic bushings - silicone grease (not aggressive to plastic).

Open and close the lid several times to distribute the lubricant evenly.

If the squeaking does not go away, it may be worn out. plastic hinge bushings. In this case, they need to be replaced. For Almera G15 fit bushings from Nissan 80530-BM000 (set of 4 pieces). Cost - approx. 800–1,200 rub.

In advanced cases, the creaking may be caused by hinge deformation (for example, after an accident or careless opening). In this case, the hinge assembly will need to be replaced (the original article number is Nissan 80500-BM000 And 80501-BM000 for the left and right sides respectively).

What to do if a squeak appears after replacing the stops?

If the squeak occurs immediately after replacing the gas stops, most likely the problem is due to incorrect installation. Check:

1. Are the stops skewed (should be strictly vertical in the closed position).

2. Do the stops touch the body or cover when driving?

3. Are the hinges of the new stops sufficiently lubricated (sometimes they come without lubricant from the factory).

If everything is in order, but the squeak remains, try applying graphite lubricant to the rubbing surfaces of the hinges.

Replacing the trunk lock Nissan Almera G15

Trunk lock Almera G15 may fail for several reasons:

• 🔐 Wear of the cylinder (the key turns with difficulty or does not turn at all).
• 🔋 Corrosion of the mechanism (especially important for cars operated in regions with salty roads).
• 🔌 Electric drive breakdown (in configurations with a trunk opening button).

To replace the lock you will need:

• 🔧 Key on 10 mm.
• 🔧 Screwdriver with a flat tip.
• 🔧 New lock (original article number - Nissan 80520-BM000 for mechanical lock or Nissan 80520-BM010 for electric version).

Replacement instructions:

1. Remove the inner lining of the trunk lid (it is secured with plastic clips).
2. Disconnect the rod that goes from the lock to the opening mechanism.
3. Unscrew the two bolts securing the lock (the key is on 10 mm).
4. Remove the old lock and install the new one in reverse order.
5. When replacing a motorized lock, connect the power connector (it is located under the trim on the right side).

Cost of a new lock:

• Mechanical - 1,500–2,500 rub.
• With electric drive - 4,000–6,000 rub.

If the problem is only in the larva, it can be replaced separately (article number - Nissan 80525-BM000, price - approx. 800–1,200 rub.). To do this:

1. Unscrew the locking screw at the end of the cylinder (flat blade screwdriver).
2. Insert the key and turn it to the "unlock" position.
3. Pull the cylinder out of the lock body and install a new one.

Frequently asked questions about the trunk lid Nissan Almera G15

Is it possible to drive if one gas stop is broken?

Technically possible, but not recommended. The stop alone will not be able to support the weight of the lid, and it will sag or close abruptly, which can cause damage to the hinges or body. It is better to temporarily secure the cover with a rope or belt until you replace the stop.

Why did the trunk lid close with a bang?

This is a sign that the gas stops have lost their seal and are not holding the lid in the up position. When closed, it falls under its own weight, causing a bang. The solution is to replace the stops or adjust them (if they are still partially working).

How to lubricate hinges if they are hidden under plastic covers?

It is necessary to remove the plastic hinge plugs. They are attached with latches - pry them off with a flat-head screwdriver (carefully so as not to break them). After lubrication, reinstall the plugs, making sure they click into place.

What to do if the trunk lock is stuck in the closed position?

Try treating the larva first WD-40 and gently move the key. If this does not help, you will have to remove the trunk lid trim from the passenger compartment (by folding back the rear seat) and open the lock manually by pulling the rod. As a last resort, you can drill out the cylinder, but then it will need to be replaced.

Will gas struts from other Nissan models fit?

No, the stops are from Nissan Qashqai, X-Trail or Juke do not fit - they have a different length and force. For Almera G15 Only original stops should be used 80510-BM00A/B or their analogues with the same parameters (420 mm folded, force 400–500 N).
