Why Doesn’t the Trunk Lid Stay Open?

Imagine this: you open the trunk to load your shopping, and the heavy lid immediately drops, risking a hit to your head. Many car owners are familiar with this annoying issue. Why does the trunk lid refuse to stay open? Let’s look at the causes and solutions. You can also add style and recognition to your car by using tuning accessories, available in our wide product range.

Main causes of malfunction

The trunk lid is held by special mechanisms. Here are the key factors that lead to failure:

• Wear of gas struts (shock absorbers): Over time, the gas inside loses pressure and the pistons wear out. This is the most common cause – up to 80% of cases.
• Spring or torsion damage: In older car models, springs stretch or break under load.
• Corrosion and dirt: Moisture and road salt damage metal parts, blocking movement.
• Mechanical damage: Impacts, accidents, or overloading the trunk deform hinges and mounts.

How to diagnose the problem

Check it yourself:

1. Open the trunk and slowly release it — if it drops sharply, the struts are weak.
2. Inspect the dampers for oil stains or rust.
3. Check the hinges for play and squeaks.

Ways to fix it

• Replace the struts: Buy original or compatible parts. Installation takes 15–20 minutes.
• Clean and lubricate: Remove dirt and apply silicone grease.
• Professional repair: If the hinges are damaged, contact a service center.

Regular inspection will extend the mechanism’s life. Now your trunk will stay securely open.
