Symptoms
- Trunk doesn't click shut on the first try
- Trunk pops back open, sometimes while driving
- Dashboard may show a trunk-open or ajar warning
- Trunk may appear closed but not be fully seated
Likely causes
- CommonMisaligned trunk strikerThe pin the latch grabs can shift slightly out of position over time or after heavy use.
- CommonWorn or dirty latch mechanismOld grease, rust, or wear inside the latch can prevent a full, secure catch.
- PossibleObstruction in the trunk seal areaDebris or a shifted weatherstrip can prevent full closure.
- PossibleBroken latch assemblyInternal latch parts can wear out or break after years of use.
What to do
- Check for anything in the way along the trunk seal or latch area.
- Inspect the striker pin for visible misalignment with the latch opening.
- Clean and lightly lubricate the latch mechanism with a dry lubricant.
- Try closing the trunk firmly but don't force it if clearly misaligned, to avoid further damage.
- Have a shop adjust the striker position if cleaning doesn't resolve it.
- Do not drive with an unlatched trunk, since it can fly open; secure it temporarily with a strap only until it's repaired.

When to call a pro
See a shop if striker adjustment doesn't fix it, since a worn latch mechanism should be replaced rather than repeatedly forced shut.
Safety
Use caution
Do not drive with a trunk that won't latch securely, since it can pop open while moving and become a hazard to traffic behind you.
