The trunk only open partially when I press the electric trunk opener button.

Hi, is this a liftgate? More than a trunk -- the liftggate does not go all the way up? I would suggest it's either seeing our experiencing restriction on its way up and causes it to stop. It could be the lift motor itself, or some other related physical restrictions of the tailgate. Hands on inspection is needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
