General Motors introduced the Multi-Flex tailgate with the 2021 Chevy Silverado 1500, offering a Chevy-branded version of GMC’s MultiPro tailgate that includes the same capabilities and functions. However, the Multi-Flex tailgate can also result in damage when dropped on a ball hitch, as GM Authority covered previously. There is, however, a solution to this problem.
As a brief recap, the Chevy Silverado’s Multi-Flex tailgate includes an inner tailgate function that hinges the upper-most portion of the tailgate, thus allowing it to swing down and provide the user with things like a full-width step up into the bed, an inner gate load stop, and an inner gate work surface. However, if the inner gate is dropped with the primary gate already lowered and the vehicle is equipped with a ball hitch, then it could be damaged.
With that in mind, a recent post from GM TechLink outlines how to disable the inner tailgate from dropping in order to prevent any potential damage.
Looking at the Chevy Silverado Multi-Flex tailgate, we see two buttons located on the tailgate itself, including an upper button and a lower button. The lower button opens the primary gate, while the upper button opens the inner gate. Press both to open both gates at the same time.
To disable the inner gate, users can press and hold the upper tailgate button for three seconds. The key fob must by within three feet of the rear bumper for this to work. After three seconds, the taillights will flash, indicating that the inner tailgate has been disabled.
To reenable the inner gate function, once again press and hold the upper tailgate button for three seconds. The taillights will flash, indicating that the function is once again active.
As GM Authority covered previously, tailgatefix.com developed a product that also prevents the inner gate from dropping when a ball hitch is attached, with customers offered a manual override switch and an auto-engage override switch.
