It should be covered under warranty!

The key fob wouldn't open it, nor would the button on the trunk lid itself. I released it using the emergency release inside (by crawling in through the back seat opening) and shut it. Driving off, the warning came back on.

Upon getting home, the trunk still wouldn't open and the car was still convinced the trunk was ajar. After an inspection I found the culprit:



Cut wire. Notice how there's no loom or protection of any kind there? While it doesn't pass through metal (though it looks like it in the picture), it appears that over time the moving and folding of the wires as the trunk lid is opened and closed caused the wire to weaken, and it finally broke in half.

Today I drove it in to work to let a coworker who does electrical reconnect it - thus documenting the problem and avoiding any potential future warranty issues (thanks to Mike for fixing it, by the way!). As I was backing up into the bay though, he called out to say my reverse lights started flickering - and then they cut out entirely.



Following a repair of the wire, it and the rest were then taped up and covered in a section of wire loom, as they should have been from the factory. The reverse lights work again, the trunk opens as it should, and the warnings are gone from the cluster.

The rest of the wires were still in good shape but that one had had enough and split in two. So sedan owners, check to see if your wires are covered, and if not note that you could have a problem if one weakens like this one did.
Thanks to Twenty I inspected the trunk wiring and found a broken wire as well. The wiring is not protected other than electrical tape. Routing of the wiring is mediocre at best. How and where the wires are mounted puts undo stress on them every time the trunk is opened and closed. Poor design...

Hi Twenty,

I'm having the same issue with my trunk lid not opening. Thought it was the fuse or the key fob battery, but no luck there... Took it to my dealer and they couldn't find the problem...

Can't view the links to your photos that you posted (blocked at work), but I'll try viewing them when I get home.

And I'll start looking at the wiring as well...

Thanks,

Dave

I'm not sure if the wiring loom will do much anyway, my wiring has a tight bend in it which in your photos looks like the exact spot it broke.

Superlifted06FX4 Interesting. My trunk keeps popping every time I'm on the freeway. Very freaky at 70+ mph.
