Power trunk or liftgate won't open electronically

A power trunk or liftgate that won't open via button is usually a blown fuse, a stuck latch, or a failed switch, though it can often still be opened manually as a workaround.

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

  1. Try all available methods to open it: interior button, key fob, and any exterior release button or handle.
  2. Check for a manual trunk release, often located in the trunk itself or driver's footwell, if button methods fail.
  3. Check the fuse box for a blown trunk/liftgate release fuse and replace with the correct amperage.
  4. Listen for a clicking or humming sound when pressing the release, which suggests the solenoid is trying but not fully releasing.
  5. Inspect the latch area (once open) for any visible misalignment or obstruction.
  6. Avoid forcing the trunk open with excessive force, which can damage the latch or body panel.
  7. Have a shop replace the trunk latch/solenoid assembly if it's confirmed as the failed part.
  8. Get the release switch tested if the solenoid seems to be receiving power correctly.
