2017-2025 Honda Ridgeline Hard Tonneau Cover: Leaks, Recalls, and Buyer's Guide
This guide covers the common leak points, a critical safety recall, and what to inspect before buying a used OEM hard tonneau cover for a 2017-2025 Honda Ridgeline.
- A critical safety recall affects 2017-2020 models; the rear panel can detach at speed. Verify the recall fix (a tether strap) has been installed on any used cover.
- The cover is water-resistant, not waterproof. Expect minor leaks; major leaks suggest bad seals or improper installation.
- Installation is simple, requiring a T-50 Torx bit to swap factory tie-downs for new brackets, and takes under an hour.
- The main OEM accessory part number is 08Z07-T6Z-101F, which supersedes earlier versions. The numbers 74730-T6Z-A00/A90 refer to a component part, not the full kit.
Known Issues, Recalls, and Service Bulletins
Safety Recall: Panel Detachment Risk (2017-2020 Models)
Critical Safety Recall: Honda issued a recall for Genuine Accessory hard tonneau covers sold for 2017-2020 Ridgeline trucks (NHTSA Campaign: 20E068000 / Honda Recall: F8M). The recall addresses a defect where, if the cover is not properly secured, wind resistance at highway speeds can cause it to buckle, deform the hinges, and allow the rear panel to completely detach from the vehicle. A separated panel creates a significant road hazard, increasing the risk of a crash or injury for other drivers.
The Fix: The recall remedy, performed by dealers free of charge, involves installing a tether strap between the center and rear panels to prevent separation. Dealers also apply new warning labels and provide an updated user manual. When buying a used cover, it is essential to verify this recall work has been completed.
🎬 Watch: A detailed explanation of the panel detachment recallCommon Problem: Water Leaks
A frequent complaint from owners is water leaking into the truck bed. A Honda ServiceNews bulletin from March 2017 clarifies that the cover is designed to be water-resistant, not completely waterproof. Leaks are most common at the folding seams and in the front corners of the bed near the cab. In some cases, water can pool in the channel between the cover and the rear window, seeping in over time.
To minimize leaks, ensure the cover is installed correctly with the weather seals properly seated and not folded over. Some owners have found success by adding butyl tape or black silicone to the gaps in the front corners of the bed rails to create a better seal.

Aside from the critical panel detachment issue addressed in the recall, there are several other signs that a Ridgeline tonneau cover may be failing or in need of attention.
- Water in the bed: The most common symptom. While no cover is 100% waterproof, excessive water pooling in the bed after rain points to failing seals or improper installation.
- Damaged or deformed hinges: Check the hinges between the panels for cracks, stress marks, or bending. This was a primary concern in the recall.
- Worn weather seals: The rubber seals around the perimeter and between the panels can become cracked, brittle, or compressed over time, reducing their ability to keep water out.
- Fading or discoloration: The panel surfaces can become sun-bleached or faded over time from UV exposure, which is a cosmetic issue.
- Broken latch handles: The plastic handles used to unlatch the cover from the rear can feel cheap and may crack or break with use.
Buying a Used Cargo Cover: Inspection Checklist
A used OEM tonneau cover can be a great value, but careful inspection is key. The OEM cover is known for its sturdy build, but it has specific weak points to check.
- Confirm Recall Compliance: This is the most important step. Ask for proof or visually inspect for the recall tether strap connecting the center and rear panels. If the cover is from a 2017-2020 vehicle and lacks the tether, it is unsafe and should be avoided or have the recall performed.
- Inspect All Seals: Carefully check the rubber weather seals on the entire perimeter and between each folding panel. Look for dry rot, cracking, missing chunks, or areas that are permanently compressed. A flashlight can help you spot hardened or damaged sections.
- Check Hinges and Panels: Fold and unfold the cover several times. The motion should be smooth. Inspect the hinges for any signs of stress, cracks, or warping. Look at the top surfaces for any signs of delamination or deep gouges that could compromise the structure.
- Test the Latches: Operate the release handles multiple times. They should engage and disengage smoothly. Check the plastic handles for any cracks.
- Verify All Hardware is Included: A complete used kit should include the main cover assembly and the specific mounting brackets that replace the factory tie-down points in the bed. Missing these brackets will require purchasing them separately.

Prices for the Honda Ridgeline hard tonneau cover can vary significantly. Here is an estimated breakdown:

Installation Overview
Installing the OEM hard tonneau cover is a straightforward DIY job that typically takes less than an hour.
- Difficulty: 2 out of 5
- Tools Required: Ratchet, T-50 TORX bit, Torque Wrench. (Note: Some sources mention a T-30 bit, but T-50 is more commonly cited for the main bed bolts).
The basic process involves using the Torx bit to remove the six factory bolts and tie-down anchors from the sides of the bed. You then install the new, cover-specific mounting brackets in their place. Once the brackets are installed, the tonneau cover assembly is placed on the bed rails and secured to the brackets using clamps. No drilling is required. 🎬 See this step-by-step OEM installation walkthrough Final adjustments to the clamp tightness are important for ensuring the cover sits flat and minimizes water leaks.
Frequently Asked Questions (FAQ)
Is the Honda Ridgeline tonneau cover waterproof?
No, it is not 100% waterproof. Honda and owner experiences confirm that the cover is water-resistant, but some water may enter the bed during heavy rain or car washes, particularly near the cab and at the folding seams.
Does the tonneau cover have to be removed to fully open the in-bed trunk?
No, the OEM hard tonneau cover is designed to allow the in-bed trunk to open fully while the cover is closed. However, some aftermarket covers that use a rail system may slightly limit how far the trunk lid can open.
What part number is affected by the recall?
The recall specifically mentions Honda Genuine Accessory Tonneau Covers with part number 08Z07-T6Z-100F, sold for 2017-2020 Ridgeline trucks. However, because accessories are not always tied to a specific VIN, Honda notified all owners of these model years to have their truck inspected.
Can you drive with the tonneau cover partially open?
The cover is a tri-fold design that can be folded up and secured in an open position against the cab. However, the recall highlights the danger of driving if the cover is not *properly* secured in either the fully closed or fully open position. Always follow the instructions for securing the cover with its integrated straps and buckles before driving.
