A faulty latch

The users who complain about the Lomax Tonneau Covers mostly mention that its latch stops working after a moment. The latch stops fastening and makes it difficult to close.

Fortunately, repairing a faulty latch is quite easy. Simply adjust the tension plate to get a tighter grip.

Plus, while locking the latch, make sure you hear a clicking sound. It’s the only indication that your cover’s latch is locked completely.

Loose Grip

If you close the tailgate more often before fastening your bed cover, you may experience a loose grip on your bed cover.


If the side rails that usually hold the cover in place shift, the cover can cause a loose grip. It’s a huge source of headache for any vehicle owner. The reason is that they don’t get adequate protection from the loose grip tonneau cover.


The fastest way to solve this problem is by realigning the bed cover’s side rails. This way, you can considerably improve the latch grip.

If you installed your Lomax tonneau cover by yourself, realigning its side rails should be a simple task for you.

But if you installed the bed cover yourself, take it to the professional mechanic to realign it safely and successfully. Otherwise, you could damage your Lomax tonneau cover completely.

The Latch Pops out during driving the truck

It’s a serious problem with the Lomax tonneau cover as it can cause you to lose your cargo easily while driving.

After fixing the accumulation problem, identify and fix the leaks. Pour some water on the bed cover and mark the spots to indicate whether the water is leaking.


Buy some high-quality seals from an auto shop or hardware store that resemble the color of your bed cover and apply them to the bed.

After sealing, check whether or not the leaks are fixed. You can also go inside the truck’s bed to check the leaks properly. Still, if you discover leaks, reapply some sealant.

Squeaky Noises
