Open Trunk??
I have an 09 C300
Twice now I have come out and found my car with the trunk open. My doors are all locked but the trunk open. I know if I push the trunk open button on my remote, it only opens the trunk but keeps the doors locked, however, I know didn't unknowingly push this button.
Anyone else have this issue?
I really like the car but the longer I have it, the more same old gremlins are showing up (slow reverse, rear wheel brake dust etc)
Thanks

J/K I think there is an emergency button(Green) inside the trunk that would pop the trunk open. Maybe that is jammed or activated somehow

This has been discussed previously. Your pants are too tight. When you bend over, you're pressing the open trunk button.
Happens to me now and again. I have a new nightly routine: look in the garage to see if the trunk is popped!

I wish it was that simple, I don't have my keys in my pocket and i'm pretty far away from car. That's whats strange about this, i wonder if another cars remote frequency is causing my trunk only to pop open, doors stay locked

I think it's you. I too have inadvertently pressed the trunk button when turning the key in the ignition slot. Too many times I've had to jump out and slam the lid closed.

Well, you never know when you might need to go somewhere 
Yes, sometimes I do that. But it's also true I keep them in a small straw basket and other things get dropped down on top of them. Whoops! The trunk just opened, again!
I think a slide switch would be a better approach ....

happened to me as well, my manager came to me and said, why is your trunk opened...I think if you have multiple keys in your pocket, the buttons might get pressed accidentally when you sit down...so far only once tho

By what is reported I'd say it's a transient fault occurring when the doors are locked by key. Have it checked next time you go for service (or sooner if you wish). It may be one of those things that is annoying and tough to locate, but they should do it readily.

It has happened to me before and this while i had laptops in the trunk. Anyway i did bring it to the dealer for a checkup but they couldnt find anything. Since then I keep my keys in the 5th pocket of my jeans or just in my bag. Haven't had any issue since. I am convinced that it is our own doing. Had the same thing happen with my old car (Accord) and that time thieves stole PS2 and bunch of bluetooth headphones

Have you tried the spare key? I would be surprised if it didn't work.
If it doesn't then you should absolutely be able to access it by folding down the backseat. Check behind the headrests on the back seats for a lever, button or handle.You may have to pull quite hard but it should work.
