Dodge Durango Liftgate Lock Actuator Guide for 2015-2023 Models
Is your Durango's power liftgate acting up, refusing to open, or making strange noises? This guide is for you.
- Common failure symptoms include the liftgate not opening, making a buzzing noise, or not latching securely.
- Replacement is a DIY-friendly task that can be completed in under two hours with basic tools.
- If the liftgate opens but won't stay up, the problem is the lift supports (struts), not the actuator.
- Verify the exact part number for your Durango's VIN, as multiple designs exist for this generation.
Is Your Durango's Liftgate Lock Actuator Failing?
A failing liftgate lock actuator on a 2015-2023 Dodge Durango can be a major inconvenience. The symptoms often start small and get worse over time. You might first notice an unusual noise or that it takes a couple of button presses to get the liftgate to respond. Eventually, it may fail completely.
Common Symptoms of a Bad Actuator:
- Liftgate Won't Open or Close: The most obvious sign is when the liftgate doesn't respond to the key fob, interior button, or exterior handle.
- Unusual Noises: You may hear a buzzing, clicking, or grinding sound from the latch area when you try to operate the liftgate, but the latch doesn't release.
- Intermittent Operation: The actuator might work sometimes and not others, often getting worse until it stops working altogether.
- Failure to Latch or Cinch: The liftgate may close but won't pull itself fully shut, leaving it ajar. This can trigger a "liftgate open" warning on your dashboard.
- Stuck Shut: In some cases, the mechanism fails entirely, and the liftgate gets stuck closed, requiring you to access the manual release from inside the vehicle.
Pro Tip: If your liftgate opens but won't stay up, the problem isn't the lock actuator. That issue is caused by weak or failing lift supports (gas struts), which are separate parts.

When replacing the liftgate actuator, you have two main choices: a new OEM part from Mopar or a new aftermarket part. For the 2015-2023 Durango, Dorman is a widely available aftermarket brand that produces direct-fit replacements.
OEM vs. Aftermarket (Dorman)
OEM Mopar: This is the original part your Durango was built with. It guarantees a perfect fit and original quality. However, it is also the most expensive option, with prices varying significantly depending on the exact part number for your vehicle's specific configuration.
Aftermarket Dorman: Dorman offers a more budget-friendly alternative. The company engineers its parts to match the fit and function of the original and states they undergo extensive quality testing. For many owners, this provides a good balance of price and reliability for a common repair like this.
Important: Several different latch assemblies were used across these model years. Always verify the correct part number for your Durango's specific build date and features before ordering.

Frequently Asked Questions
Can I replace the Durango liftgate actuator myself?
Yes, this is a DIY-friendly job for someone with basic mechanical skills. The process involves removing the interior liftgate trim panel, disconnecting a few electrical connectors, and unbolting the old actuator to install the new one. 🎬 Watch this step-by-step guide to replacing the locking latch. You will need a trim removal tool and a basic socket set.
Is there a recall for the liftgate lock on my 2015-2023 Durango?
No, there are no active recalls for the liftgate lock actuator on these models. There was a recall for 2021-2023 models related to the rear spoiler potentially hitting the roof, but it does not involve the lock mechanism. There is also a Technical Service Bulletin (TSB) for a small number of 2023 models for a striker alignment issue, not a faulty part.
How do I open the liftgate if the actuator is completely broken?
You will need to climb into the cargo area. On the interior trim panel of the liftgate, there is typically a small access cover. Prying this cover off will give you access to the manual release lever on the latch mechanism, allowing you to open the gate.

These terms are often used together. The lock actuator is the small motor within the latch assembly that specifically handles the locking and cinching. The term "liftgate motor" can sometimes refer to the larger power drive unit that physically raises and lowers the entire liftgate. The part that commonly fails and prevents opening is the lock actuator/latch assembly.
