A common problem we see often is that a Mercedes-Benz trunk won't stay closed. This is a problem with Mercedes-Benz cars that use a power trunk lid and can affect various models including C-Class, E-Class, S-Class models etc. 

The trunk won't stay close because the car loses the memory setting for the trunk. This is a problem that usually happens after the car battery dies or the battery gets replaced. Pressing the green trunk release button inside the trunk a few times will allow your trunk to close in most cases.

  1. Open the trunk all the way up. Open trunk all the way up
