If your Mercedes Benz trunk won’t close, what should you do? This article covers all the things you need to check, with solutions

Mercedes-Benz vehicles are known for their luxury and advanced features, but sometimes even the best vehicles can encounter issues.

One common problem that Mercedes owners might face is a trunk that won’t close, lock, or shut properly. This can be both an inconvenience and a safety concern if not addressed in a timely manner.

Mercedes Benz Trunk Won't Close

There could be several reasons why a Mercedes trunk won’t close, ranging from a simple setting adjustment to a more serious mechanical problem.

By understanding these causes, you can diagnose and possibly fix the issue without needing to visit a mechanic, saving you both, time and money.

In this article, we will explore the possible causes and solutions for a Mercedes-Benz trunk that won’t close.

Common Reasons for a Stuck Trunk Lid

Faulty Trunk Latch

Probably the most common reason for a Mercedes Benz stuck trunk lid is a faulty trunk latch. This can be due to a design flaw or simply wear and tear. In some cases, a bad trunk latch can prevent the trunk from closing, locking, or shutting properly.

To troubleshoot a faulty latch, first try pressing the green button located on the trunk lid, in some Mercedes-Benz models, this can be found inside the trunk. If this doesn’t help, it’s likely that the latch needs to be replaced.

Electrical Issues

Another possible reason why your Mercedes trunk might be stuck can be electrical issues within the vehicle. Potential problems may include a blown fuse, malfunctioning trunk release or faulty wiring.

Before assuming an electrical issue, check the fuse box for blown fuses. If you find a blown fuse, replace it and try opening the trunk again. This handy video shows you how you can locate the fuse box on your Mercedes.

Hindered Movement

Lastly, a stuck trunk lid may be due to hindered movement. This can happen if there is any physical obstruction preventing the lid from closing or if the hinges have become rusted or damaged.

If you notice any physical obstructions, remove them and try closing the trunk again. To tackle rusted or damaged hinges, lubricate them with an appropriate product, such as WD-40, and ensure they’re free from debris.

Troubleshooting Tips to Fix a Mercedes Benz Trunk That Won’t Close

Inspect the Trunk Lid and Latch

Start by examining the trunk lid and latch for any visible issues. Look for debris, misaligned parts, or broken components.

You may need to lubricate the latch mechanism with a silicone spray. Reference a repair guide or your vehicle’s manual for detailed instructions on your specific model.

Check for Electrical Problems

The trunk closing issue may be due to electrical issues as well. Check the e-trunk button for proper functioning. Examine wiring connections, and ensure there are no damaged or loose wires.

In some cases, a simple fuse reset can resolve the problem. Consult your manual for the correct fuse location, and try removing it for 15 seconds before reinstalling.

Test the Trunk Lid Actuator

A faulty trunk lid actuator may be the cause of your trunk not closing. To test it, disconnect the actuator and manually close the trunk. If the trunk closes without issue, the actuator likely needs replacement.

Refer to your vehicle’s manual or a repair guide for specific instructions on testing and replacing the actuator in your Mercedes Benz.

Examine Trunk Struts and Supports

Inspect the trunk struts and supports for any signs of wear or damage. Worn or damaged struts can prevent the trunk from closing properly.

If necessary, replace the struts to ensure the smooth functioning of your trunk.

Other Ways to Fix the Issue

When experiencing issues with your Mercedes-Benz trunk not closing, it’s essential to reach out to your local MB dealer. They can diagnose the problem, offer solutions, and provide support.

You may also consult an ASE-certified engineer about your trunk issue. They possess the necessary expertise and experience to assist you in the most reliable way.

If your Mercedes-Benz is under warranty, it’s advisable to take advantage of it! Check your warranty details and visit your dealership to receive expert assistance for your trunk issue.

Preventive Measures to Avoid a Stuck Trunk

Regular Maintenance of Trunk Parts

To prevent Mercedes-Benz trunk problems, regularly inspect the latch and other trunk components.

Faulty latches can cause the trunk to remain open. Lubricate the latch and hinges to ensure smooth operation. Check the trunk’s pump and windshield for proper functioning to avoid trapped water.

Weatherproofing the Trunk Area

Protect the trunk from elements to avoid rust or debris buildup. Start by cleaning the trunk and surrounding area thoroughly.

Apply a layer of weatherproof sealant on the trunk’s edges. This helps maintain the trunk’s form and prevent water seepage.

Operating the Trunk Carefully

Always operate your Mercedes-Benz trunk with care. We recommend closing the trunk gently and avoiding slamming, which can damage the latch and other parts.

Remember to check the trunk regularly for any visible signs of damage, and promptly address any issues you find.

Signs of a Faulty Trunk Latch

To effectively troubleshoot a trunk that won’t close, it’s crucial to identify the signs of a faulty trunk latch. Look out for indicators such as the trunk lid not securely latching, difficulty in locking or unlocking the trunk, or unusual noises when attempting to close it.

Additionally, if you notice the trunk popping open unexpectedly while driving, it could be a clear indication of a faulty latch. Being aware of these signs will help you diagnose the issue accurately and take appropriate measures to address it.

Steps to Reset the Trunk Release Button

In some cases, a malfunctioning trunk release button can cause the trunk to remain stuck or unresponsive. To troubleshoot this issue, you can try resetting the trunk release button.

Begin by locating the fuse box and identifying the fuse corresponding to the trunk release function. Remove the fuse for approximately 15 seconds and then reinsert it firmly.

This simple reset may resolve any electrical glitches and restore the proper functioning of the trunk release button.

However, it’s important to consult your vehicle’s manual or a repair guide for specific instructions and the correct fuse location, as it may vary depending on your Mercedes-Benz model.
