I have the same issue. Lost a lure, bought the same lure and caught a bass but as soon as I brought him in land, the trilene slipped. Close call! I’ll be going back to palomar

I've had issues with Trilene knots slipping, but only on heavier test line.  With 10# line and below, the knot cinches down nice and tight.

I lost 3 last week on the 'improved trilene knot' on 10 lb hybrid line. I believe I wasn't cinching well. Got very frustrated and started cinching hard and after wetting the line and didn't have further issues. Been using this knot my whole life without issue so I was surprised. The line may have contributed. I may switch to Palomar, I use that on braid but never have on anything else. I was thinking it'd be easy to kink the line which may weaken it?

I have tried hundreds, if not thousands of Trilene (aka: double improved clinch) knots, and don't recall ever having them slip. I do carefully cinch them down, and then leave close to a 1/8" tag on them.

 

These days though, any time I would be tempted to use a Trilene knot, I now use the San Diego Jam knot, or sometimes if I really want to be certain a knot won't fail, the Double San Diego Jam gets the call.

 

My knot game is mostly the Alberto for braid to leader, Palomar for hooks and other terminal tackle, and the SDJ for other more expensive baits. I can get by most days with just those.

I'm a Palomar fan, but when my leader is getting short I will use a Trilene in order to save material;  on most knots, when I finish tying them, I will add a half hitch to cinch them down tight.  That is just a confidence thing for me.

The San Diego Jam can be tied to leave a very short tag in that situation too. It doesn't seem like it will until you cinch it up. 

I used the Trilene knot for years and started having issues with it when used with Yozuri Hybrid line. I switched to the uni and it fixed all the issues.
