5 Common Mercedes Tailgate Problems (Explained): Solutions Included

Mercedes is a luxury car brand expected to be dependable in terms of performance and functionality. That is not always the case, however. Even Mercedes owners are bound to run into some problems.

Not to say that Mercedes vehicles are without flaws. In fact, they are far from it. However, if you own a Mercedes, you may encounter some tailgate issues.

It is critical to becoming acquainted with these issues so that you will know what to do if they occur to you.

We combed the internet and discovered that the following tailgate issues are common in most Mercedes vehicles. We’ve also included solutions to the problems.

1. The tailgate must be manually closed or opened.

The Mercedes tailgate’s automatic opening and closing feature is one of the best features ever added to this vehicle.

All you have to do is press the tailgate button on the key fob to open the tailgate. When you’re finished, you can close the trunk by pressing a button on the side.

After a while, This automatic function may fail, forcing you to manually open and close the tailgate.

Those accustomed to this impressive feature may find it extremely difficult to live without it. After all, if it was working previously and has now stopped, it should be repaired.

If the automatic opening and closing feature on your Mercedes tailgate isn’t working, you should first check the connection beneath the trunk.

When you press the key fob to open the tailgate, the motor receives the command and sends it to the locking mechanism via the wiring. Then your trunk opens.

This mechanism will not function if a fault is somewhere along the connection.

In most cases, the switch found in the manual tailgate handle is to blame. That switch could become stuck in the open position, disrupting the automatic opening feature.

Because it would already be open when you signaled it to open, examine the handle and try to press the microswitch until it frees up.

2. The Trunk Is Still Closed

Another common issue with the Mercedes tailgate is when the trunk remains closed while attempting to open it with the key fob. This is a common issue with all vehicles, not just Mercedes.

A trunk that remains closed can be problematic and inconvenient for anyone, especially if you use the trunk to load cargo regularly.

A faulty actuator is the most common cause of a trunk that refuses to open. An actuator is a device that regulates the trunk’s locking mechanism. If it’s dead, it won’t be able to open when you click on the fob.

There isn’t much you can do if your actuator is dead other than replace it. Actuators cannot be repaired, and in most cases, there is no need for a repair because actuators are relatively inexpensive. You can get one from a local auto parts store.

To ensure that the actuator is completely compatible, purchase one that matches the code of the existing one. You can also purchase one on eBay. If you are having difficulty reaching the location of the actuator, consult your manual for assistance.

There is one thing you must remember. If your actuator isn’t working, the tailgate won’t open from the inside.

It would be completely closed. If you can open the trunk from the inside, look into other options, such as a faulty switch.

3. Defective Latch

A faulty latch is another issue that has been widely reported, particularly among the ML versions. A latch is a device used to secure the tailgate. A faulty latch can cause problems in a variety of ways.

First, it may not tie the tailgate to the car at all. That means you will drive around with an open tailgate, which is risky and unsafe. Second, you may hear whirring noises from the latch when closing the tailgate.

Unfortunately, a broken latch will also necessitate replacement. Otherwise, it will be an annoyance for the rest of the vehicle’s life.

Repairing the latch, according to user feedback, never works. Even if you fix the whirring, the tailgate will still not latch.

To avoid this, take your Mercedes to the dealer and have the entire latching mechanism replaced. This could be expensive, especially if your car’s warranty has expired. However, it would be worthwhile to avoid the costs.

4. Inability to open the tailgate with the key fob

New technologies, at times, are fraught with complications. The ability to open a Mercedes with a key fob is a good example.

It was first introduced a few years ago. The majority of Mercedes owners well received this feature. Years later, however, there have been several complaints that the key fob does not always open the trunk.

Before you inspect the tailgate, if your key fob cannot open the trunk, check to see if the key fob’s battery is dead. It can be that simple at times. A dead key fob battery cannot open your Mercedes tailgate or doors.

Check to see if the fob can open the doors. If they cannot do so, you should replace the key fob’s battery. If the doors can be opened, but the tailgate is still resistant, the condition of the tailgate can be determined.

5. The tailgate will only open to a certain height.

This isn’t a major issue but a setting in most Mercedes vehicles. After some time, tailgates can reset themselves to their default settings. In other words, the tailgate may only open to a certain height.

If you become a victim of this, you do not need to look for any problems with the actuator or latches. The tailgate must be reset before it opens to the desired height.

Here’s a quick guide to resetting the tailgate and making sure it opens to the correct height.

First, make sure nothing is blocking the tailgate from fully opening. Mercedes has a safety feature that prevents it from fully opening if an object, such as a garage door or a tree, is in the way.

Pull the tailgate handle to reset the tailgate. Keep an eye on it as it opens, and wait for it to reach the desired height. Close the door at the desired height by pressing the closing button. The tailgate should come to a halt at that point.

When the tailgate is in that position, press and hold the closing button to store it. Two short-tone sounds should be heard. You have successfully reset the tailgate if you close it.

Give it a shot and see if it works. Your Mercedes tailgate should open to the height you specify.

These are the five most common Mercedes tailgate problems, as well as possible solutions. When you have a problem with your tailgate, In order to quickly solve the issue, it is essential to conduct a thorough analysis of it.

Considering how important access to your trunk is, a malfunctioning tailgate can be quite inconvenient.

Can Leaks Cause Mercedes Tailgate Issues?

Many people are unaware that a leak around your car’s trunk can cause tailgate problems.

When water enters the latching mechanism, actuator, and wires, the tailgates may not open or close normally. It’s a good idea to check the trunk for leaks.

Inspect the condition of the links if your Mercedes has been around for a while. Also, when washing the trunk, avoid using a lot of water.

Leaks are risky because they can cause corrosion. It’s not just the tailgate that needs to be considered.

When Do Mercedes Tailgate Issues Arise?

There is no set time frame for when these tailgate issues on your Mercedes may occur. However, they are most common in vehicles with over 100,000 miles. The effects of wear and tear on a vehicle become visible as it ages.

For example, the actuator may begin to malfunction, and the key fob battery may die. These are issues that you can expect to encounter during the life of your Mercedes.

Some of these issues, however, can occur with new vehicles. If your Mercedes is less than a year old, you can take it to the dealer and have the tailgate problem repaired under warranty. You will not be charged a single penny for the repairs and replacements.

Even if your warranty has expired, you can still take your vehicle to the dealer for tailgate repairs and replacements. You will receive expert assistance with your tailgate issues at the dealership.

The other option is to take the vehicle to a Mercedes mechanic. You can also try your hand at do-it-yourself repairs. These are typically less expensive but require some mechanical knowledge and experience.
