2023-2025 Colorado Tailgate: Decoding StowFlex, Camera Options, and Water Leaks

Decoding 2023-2025 Colorado Tailgate Variations

When replacing the tailgate on a 2023-2025 Chevrolet Colorado, you must match the features of the replacement part to your truck's original equipment. Using an incompatible tailgate can result in non-functioning cameras, warning lights, or features that simply won't work. The key differences are based on three main options:

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

StowFlex Tailgate: Latching and Water Intrusion Issues

The most widely reported problem with the 2023-2025 Colorado tailgate involves the optional StowFlex storage compartment. Many owners report two primary issues:

• Poor Latching: The latches for the storage lid may not engage properly, causing the lid to flop open, especially when the main tailgate is opened. Some owners have attempted to fix this by adjusting the hinges.
• Water Leaks: Despite being advertised as watertight, the StowFlex compartment is prone to significant water intrusion from rain and car washes. This leads to standing water inside the compartment and can cause rust on stored tools and recovery gear. Some owners have removed the drain plug entirely to prevent water from pooling.

As of mid-2026, there is no official recall or widely published TSB for this specific issue, but it is a well-documented complaint in owner forums.

Recall Notice (Silverado/Sierra HD Only): Tailgate Opens Unexpectedly

General Motors issued a safety recall (NHTSA Campaign Number: 24V060000) for certain 2020-2024 Chevrolet Silverado HD and GMC Sierra HD trucks equipped with power-unlatching tailgates. In these vehicles, water can intrude into the tailgate and short-circuit the electronic release switch, causing the tailgate to unlatch and open while the vehicle is in Park.

Symptoms of a Failing Tailgate

While the tailgate shell itself does not fail, its components can. Here are the most common symptoms:

• Tailgate is Heavy or Slams Down: This indicates a failure of the lift assist mechanism (RPO PPA). The internal torsion bar or external damper has likely broken or worn out.
• StowFlex Lid Won't Stay Closed: The latches for the storage compartment are misaligned, worn, or broken.
• Water Inside StowFlex Compartment: The weather seal around the storage lid has failed or is poorly designed, allowing water to enter.
• Rearview Camera is Black or Flickering: This can be caused by a failed camera, a damaged wiring harness inside the tailgate, or a loose connection at the main chassis harness under the truck.
• "Tailgate Ajar" Warning on Dash: If the tailgate is fully closed but the warning persists, the latch sensor switch is likely faulty or misaligned.
• Tailgate Won't Open: The handle mechanism, connecting rods, or the electronic latch release could be broken.

Buyer's Guide: What to Check Before Purchasing a Used Tailgate

Buying a used OEM tailgate is an excellent way to save money, but careful inspection is crucial to avoid getting the wrong part. Follow this checklist:

1. Confirm Vehicle Options: This is the most important step. Get the VIN from the donor vehicle and use an online VIN decoder to confirm its exact options (StowFlex, Camera System, Lift Assist). Do not rely on visual identification alone.
2. Inspect the Electrical Connector: Locate the main tailgate harness connector. Compare it to your old part. The shape of the connector and the number of pins must match exactly. A different pin count means the camera or latch features are incompatible.
3. Check for Physical Damage: Inspect the shell for major dents, deep scratches, and signs of rust, especially along the bottom edge and inner seams. Check for previous bodywork (uneven paint, filler).
4. Test Mechanical Components: Operate the handle. It should move smoothly and return to its position. If it's a StowFlex tailgate, test the storage compartment latches to ensure they click securely into place.
5. Examine the Camera Lens: If equipped, check the rearview camera lens for deep scratches, hazing, or condensation, which can obscure the image.
6. Ask About the Donor Vehicle: Inquire about the mileage and condition of the truck it came from. A tailgate from a low-mileage, accident-free truck is always preferable.

Cost Comparison

Replacing a tailgate can be expensive, especially if it includes paint work. Here are typical cost estimates:

Replacement Overview

Replacing the tailgate is a straightforward job that can be done with basic tools, but it requires two people to safely lift the tailgate.

• Difficulty: 2 out of 5
• Estimated Time: 1 hour (not including painting)
• Tools Needed: Socket set (10mm), Torx bit set (T20), trim removal tool, a moving blanket to prevent scratches.

Procedure Summary:

1. Open the tailgate and disconnect the support cables on both sides by releasing their retaining clips.
2. Support the tailgate and partially close it to about a 45-degree angle. Disconnect the main wiring harness located near the passenger-side hinge.
3. With a helper, lift the passenger side of the tailgate up and off its hinge pivot.
4. Slide the tailgate to the right to disengage it from the driver-side hinge slot.
5. Place the tailgate on a soft surface. Transfer the handle, camera, emblems, and top trim panel from your old tailgate to the new one.
6. Installation is the reverse of removal. Ensure the wiring harness is reconnected securely and test all electronic functions (camera, latch) before fully closing.
