Common TruXedo Sentry CT Problems
1. Vinyl Separating from Slats

One of the most frustrating issues you might encounter with your TruXedo Sentry CT is the vinyl cover separating from the aluminum slats. This problem can leave your truck bed exposed and compromise the cover’s functionality.
Why It Happens
This separation usually occurs due to prolonged exposure to extreme weather conditions, particularly intense heat or cold. Over time, the adhesive binding the vinyl to the slats can weaken, causing the two components to come apart.
How to Fix It
If you’re facing this issue, here’s what you can do:
Clean the area: Use a mild soap and water solution to clean both the vinyl and the slat where separation has occurred.
Apply adhesive: Use a strong, weather-resistant adhesive designed for vinyl and metal bonding. Apply it carefully along the separated area.
Clamp and dry: Use clamps or heavy books to press the vinyl firmly against the slat. Allow it to dry completely according to the adhesive’s instructions.
Preventive measures: To avoid future separation, try to park your truck in a covered area when possible, especially during extreme weather.
Remember, if the separation is extensive or you’re not comfortable with DIY repairs, it’s best to contact TruXedo’s customer service for professional assistance.
2. Locking Mechanisms Breaking

A broken locking mechanism can be a major security concern, leaving your truck bed contents vulnerable.
Common Causes
Locking mechanisms often break due to:
- Excessive force when closing the cover
- Debris accumulation in the locking system
- Normal wear and tear over time
Solutions
Here’s what you can do if you’re facing this problem:
Inspect the mechanism: Check for any visible damage or debris that might be causing the issue.
Clean the lock: Use compressed air or a soft brush to remove any dirt or debris from the locking mechanism.
Lubricate: Apply a silicone-based lubricant to ensure smooth operation.
Replace if necessary: If the lock is severely damaged, you may need to replace it. Contact TruXedo for replacement parts or professional repair.
3. Poor Corner Stitching

Some users have reported issues with the stitching at the corners of the cover, which can lead to fraying or even tearing over time.
Why It’s a Problem
Poor corner stitching can compromise the cover’s integrity, allowing water to seep in and potentially damaging your cargo.
How to Address It
If you notice this issue:
Inspect the stitching: Carefully examine all corners of the cover for loose or fraying threads.
Temporary fix: For minor fraying, you can use a fabric sealant to prevent further unraveling.
Re-stitching: If you’re handy with a needle and thread, you might be able to reinforce the stitching yourself using heavy-duty, weather-resistant thread.
Professional repair: For extensive damage, it’s best to contact TruXedo or a professional upholstery shop for repairs.
4. Metal Shavings Falling Out When Rolled Open

Finding metal shavings in your truck bed when you roll open your TruXedo Sentry CT can be concerning and messy.
Causes of This Issue
This problem typically occurs due to:
- Misalignment of the cover’s components

- Manufacturing defects (in rare cases)
How to Resolve It
Follow these steps to address the metal shavings issue:
Identify the source: Carefully inspect the cover’s rails and moving parts to find where the shavings are coming from.
Clean thoroughly: Use a shop vac to remove all metal shavings from your truck bed and the cover’s components.
Lubricate moving parts: Apply a dry lubricant to reduce friction between metal components.
Check alignment: Ensure all parts of the cover are properly aligned. You might need to adjust the installation if misalignment is causing the problem.
Contact manufacturer: If the issue persists, reach out to TruXedo as this could indicate a more serious problem requiring professional attention.
5. Water Leakage, Especially at Front Corners

Water leakage can be a major headache, potentially damaging your cargo and causing rust in your truck bed.
Why It Happens
Water leaks often occur due to:
- Improper installation
- Worn or damaged seals
- Misalignment of the cover
Solving the Problem
Here’s how you can tackle water leakage:
Check the seals: Inspect all rubber seals for damage or wear. Replace any that are no longer effective.
Verify installation: Ensure the cover is properly installed and aligned with your truck bed.

6. Rubber Caps on Slats Popping Out of Place

Loose or missing rubber caps on the slats can affect the cover’s appearance and potentially its functionality.
Causes
This issue often occurs due to:
- Normal wear and tear
- Extreme temperature changes
- Improper handling when rolling the cover
Fixing the Problem
Here’s what you can do:
Reinsert loose caps: If the caps are just loose, you can usually push them back into place by hand.
Use adhesive: For caps that won’t stay put, apply a small amount of rubber adhesive before reinserting them.
Replace missing caps: Contact TruXedo for replacement caps if any have gone missing.
Preventive measures: Handle the cover gently when rolling it up or down to avoid dislodging the caps.
7. Cover Bouncing Excessively at Highway Speeds

If your TruXedo Sentry CT is bouncing more than it should when you’re driving at higher speeds, it can be both annoying and potentially dangerous.
Why It Happens
Excessive bouncing can occur due to:
- Improper tension adjustment
