Symptoms
- Trunk/liftgate button does nothing
- Latch clicks but trunk doesn't pop
- Trunk opens manually with the key but not the button
- Power liftgate opens partway then stops
Likely causes
- CommonBlown trunk release fuseA dedicated fuse for the trunk or liftgate release can blow independently.
- CommonFailed trunk release solenoid or actuatorThe small motor that pulls the latch open can wear out over time.
- PossibleFaulty trunk release switch or buttonThe interior or fob button used to trigger release can fail.
- PossibleObstruction or misalignment preventing the latch from releasingA bent latch or something blocking it can prevent proper release even with power.
What to do
- Try all available methods to open it: interior button, key fob, and any exterior release button or handle.
- Check for a manual trunk release, often located in the trunk itself or driver's footwell, if button methods fail.
- Check the fuse box for a blown trunk/liftgate release fuse and replace with the correct amperage.
- Listen for a clicking or humming sound when pressing the release, which suggests the solenoid is trying but not fully releasing.
- Inspect the latch area (once open) for any visible misalignment or obstruction.
- Avoid forcing the trunk open with excessive force, which can damage the latch or body panel.
- Have a shop replace the trunk latch/solenoid assembly if it's confirmed as the failed part.
- Get the release switch tested if the solenoid seems to be receiving power correctly.
