Avoid Costly Repairs: How to Solve GMC Multipro Tailgate Problems

The introduction of the GMC Multipro Tailgate in 2019 came with a mixed reaction. 

While the feature was welcomed as a useful innovation, many quickly pointed out several design flaws.

First, the multi-pro feature allowed drivers six configuration positions and functionality, including the primary gate load step, a full-width step and more. 

However, owners of the GMC Sierra were quick to question the practicality of the lowest configuration.

This article will discuss the causes and fixes of the GMC Multipro Tailgate.

What is the Multipro Tailgate?

GMC Multipro Tailgate feature is a multifunction tailgate configuration setting that allows the driver to configure the tailgate to carry out various tasks.

The tailgate of your GMC consists of a primary gate and an inner tailgate hinged within the main tailgate.

Furthermore, the Multipro Tailgate feature allows the driver to manipulate these two tailgate panels to take different roles and shapes. It includes forming an entry step into the truck or forming a bed extender.

The GMC multi-pro tailgate has proven to be fancy, durable and functional in the trucking industry. 

.However, their tailgate has had major design flaws, and they may have even questioned the practicality of some of their designs.

Features of the GMC MultiPro Tailgate

1. Load- Stop feature

The load-stop feature prevents loads and cargo from sliding out of the truck. You can use this feature by folding the inside panel within the inner gate to an upright position. It will form a vertical stop barrier for your loads.

2. Step feature

When the primary and inner tailgate is released fully, it forms a 48” wide step granting easy access to the truck bed. The step is durable and rated to carry up to 375 pounds.

3. Inner-gate load-stop feature

The inner gate load stop features a two-layer design that allows drivers to load longer materials like plywood. In addition, the edges of the stops protrude upward, acting as a stop for longer items and preventing them from slipping from the truck. 

4. Lowered Tailgate

Unlike the previous design used by GMC, the Multipro design appears much closer to the ground to grant users full access to the truck bed with convenience. Extending your lean is unnecessary to access the further section of the truck bed.

What are the problems with GMC Multipro Tailgate?

A couple of issues are pointed out by GMC Sierra and Silverado drivers. Some problems appear more severe than others, while some are just technological misunderstandings.

Tailgate design issue

There is a poorly designed tailgate configuration, especially with the lowest or inner section of the tailgate.

Many truck lovers have a ball hitch installed to the bottom of their trucks for towing. If you drop your tailgate to the lowest configuration, it slams on the ball hitch and possibly damages the tailgate.

Possible FIX

GMC has responded by installing a sensor to the receiver, which prevents the inner section of the tailgate from opening if a ball hitch is installed. 

While this prevents damage to your tailgate, it doesn’t fix the design flaw and instead denies you access to the full feature of the tailgate. Most drivers are less satisfied with this improvement

Load Stop issue

Another design fault with the multi-pro tailgate is the load-stop functionality. This feature was designed to stop loads from rolling off the truck, especially on steep roads.

The design also allows you to use the full length of the truck. However, many have complained that the load stop doesn’t lock in place when you raise the load stop gate.

Possible Fix

You can easily purchase a load-stop lock online and install it on your GMC truck. Installation is very easy and won’t take up to a minute.

Water or snow leak

The space between the primary and inner tailgate allows water and snow to enter, causing water-related damage. This space was a result of the GMC welding process.

Possible Fix

You can purchase a GMC tailgate seal to prevent water or snow from accumulating in the space.

The tailgate seal is a long rubber seal that stretches across the crack from the two tail points. This solution is in no way, a permanent or ideal solution. 

Over time, even these seals will break or wear off over a long time, and you might have to purchase a new one.

Noise

The GMC Multipro Tailgate produces rattling and disturbing noises. These noises may develop from rust, especially if water enters the folding parameter.

Possible fix

The best fix is to apply caulking or lubricants around the tailgate parameter. You can reduce the vibration by installing a tailgate damper. A damper helps to absorb vibration and noise from the tailgate.

Electrical Issue

Electrical issues with the multi pro tailgate have also been reported. Sometimes, the tailgate may be unresponsive or even refuse to open. 

A wiring issue most likely causes this. To fix this, inspect the wiring connection for breakage or short-circuiting.

Also, sometimes the tailgate won’t open because they have been deactivated unknowingly to the driver. 

To fix this, locate the button at the handle of the tailgate. Press down the upper button for at least 5 seconds. You should see the tail light flash. The handles should be activated now.

Frequently Asked Questions (FAQ) 

How do you disable a GMC multi use tailgate?

To disable the inner gate of your GMC, press the upper button on the tailgate handle for at least 5 seconds. Ensure the key fob is close to the tailgate when doing this. The tail light should flash.

Final Thought!

The GMC Multipro tailgate feature is a functional and innovative improvement on the GMC trucks. 

But like all great cars, there is still room for improvement. The problems discussed above don’t change the fact that the GMC Sierra and Silverado are great trucks we love. 

We hope they continue to improve and resolve most of the issues discussed.
