SYMPTOMS
Trunk fails to stay closed after using the trunk button or the key fob remote to unlock the Trunk

ROOT CAUSE
Black Rotary Actuator (for electronic opening of the trunk) in the Trunk Latch Assembly loses it's return tension, resulting in the Silver Unlock Actuator to become stuck on open, thus the trunk latch won't "catch" and the trunk won't stay closed


WORKAROUND
This should help you use the electronic
1. Remove covers
2. Remove Latch (not necessary, but makes Step 3 easier)
3. Shave (little at a time) the part of the Black Rotary Actuator which holds the Silver Unlock Actuator from returning to normal position
4. Before you shave too much, test it.

FIX & COST
Replacing the latch assembly… $280 ish for parts. Another 20 - 30 bucks for labor
Latch assembly is a dealer only part. No After Markets

//2020 UPDATE: Folks in the comments say DIY replacement with $25-$30 aftermarket part is available.
